Stem Cell Therapy - the improved diagnostics available to treat lameness

Article by Jackie Zions (interviewing Dr. Koenig)

Prevention is the ideal when it comes to lameness, but practically everyone who has owned horses has dealt with a lay-up due to an unforeseen injury at some point. The following article will provide tools to sharpen your eye for detecting lameness, review prevention tips and discuss the importance of early intervention. It will also begin with a glimpse into current research endeavouring to heal tendon injuries faster, which has obvious horse welfare benefits and supports horse owners eager to return to their training programs. Dr. Judith Koenig of Ontario Veterinary College (OVC) spends half of her time as a surgeon and teacher with a strong interest in equine sports medicine and rehabilitation, and the other half as a researcher at the OVC.

Lameness is a huge focus for Koenig, whose main interest is in tissue healing. “I think over the past 20 or 30 years we have become very, very good at diagnosing the cause of lameness,” says Koenig. “In the past, we had only radiographs and ultrasound as a diagnostic tool, but by now most referral centres also have MRI available; and that allows us to diagnose joint disease or tendon disease even more. We are much better now [at] finding causes that previously may have been missed with ultrasound.” 
Improvements in diagnostics have resulted in increased ability to target treatment plans. With all the different biologics on the market today, Koenig sees a shift in the management of joint disease with more people getting away from steroids as a treatment.

The following list is excerpted from Equine Guelph’s short course on lameness offered on TheHorsePortal.ca. It outlines the different diagnostics available:

When asked for the latest news on research she has been involved in, Koenig proclaims, “I'm most excited about the fact that horses are responding well to stem cell treatment—better than I have seen any response to any other drug we have tried so far!”

Koenig has investigated the use of many different modalities to see if they accelerate tissue healing and has studied which cellular pathways are affected. Two recent collaborative studies have produced very exciting findings, revealing future promise for treating equine osteoarthritis with stem cell therapy.  

In a safety study, Koenig and her team at the Ontario Veterinary College have shown equine pooled cryopreserved umbilical cord blood, (eCB) MSC, to be safe and effective in treatment of osteoarthritis.  

“These cells are the ones harvested from umbilical cord blood at the time of foaling and then that blood is taken to the lab and the stem cells are isolated out of it,” explains Koenig. The stem cells are then put through a variety of tests to make sure they are free of infectious diseases. Once given a clean bill of health, they are expanded and frozen. 
The stem cells harvested from multiple donors of equine umbilical cord blood [eCB, (kindly provided by eQcell), MSC] were compared to saline injections in research horses. “This type of cells is much more practical if you have a cell bank,” says Koenig. “You can treat more horses with it, and it’s off the shelf.” There were no systemic reactions in the safety study. Research has also shown no different reactions from sourcing from one donor or multiple donors.  

In the second study, 10 million stem cells per vial were frozen for use in healing OA from fetlock chips in horses that were previously conditioned to be fit. After the fetlock chip was created, exercise commenced for six more weeks, and then osteoarthritis was evaluated by MRI for a baseline. Half the horses were treated with the pooled MSC stem cells, and the control group received saline before another month of exercise. Then MRI and lameness exams were repeated, and arthroscopy was repeated to score the cartilage and remove the chip.

Lameness was decreased and cartilage scores were improved in the group that received stem cell therapy at the time of the second look with arthroscopy.

Many diagnostics were utilised during this study. MRIs, X-rays, ultrasounds and weekly lameness evaluations all revealed signs of osteoarthritis in fetlock joints improved in the group treated with (eCB) MSCs. After six weeks of treatment, the arthroscopic score was significantly lower (better cartilage) in the MSC group compared to the control group. 

“Using the MRI, we can also see a difference that the horses treated with stem cells had less progression of osteoarthritis, which I think is awesome,” says Koenig. “They were less lame when exercised after the stem cell therapy than the horses that received saline.”

This research group also just completed a clinical trial in client-owned horses diagnosed with fetlock injuries with mild to moderate osteoarthritis changes. The horses were given either 10 million or 20 million stem cells and rechecked three weeks and six weeks after the treatment. Upon re-evaluation, the grade of lameness improved in all the horses by at least one. Only two horses presented a mild transient reaction, which dissipated after 48 hours without any need for antibiotics. The horse’s joints looked normal, with any filling in the joint reduced.
There was no difference in the 18 horses, with nine given 10 million stem cells and the other nine 20 million stem cells; so in the next clinical trial, 10 million stem cells will be used.

The research team is very happy with the results of this first-of-its-kind trial, proving that umbilical cord blood stem cells stopped the progression of osteoarthritis and that the cartilage looked better in the horses that received treatment. The future of stem cell therapy is quite promising!
Rehabilitation
Research has shown adhering to a veterinary-prescribed rehabilitation protocol results in a far better outcome than paddock turn out alone. It is beneficial for tendon healing to have a certain amount of controlled stimulation. “These horses have a much better outcome than the horses that are treated with just being turned out in a paddock for half a year,” emphasises Koenig. “They do much better if they follow an exercise program. Of course, it is important not to overdo it.”

For example, Koenig cautions against skipping hand-walking if it has been advised.  It can be so integral to stimulating healing, as proven in recent clinical trials. “The people that followed the rehab instructions together with the stem cell treatment in our last study—those horses all returned to racing,” said Koenig.  

“It is super important to follow the rehab instructions when it comes to how long to rest and not to start back too early.”

Another concern when rehabilitating an injured horse would be administering any home remedies that you haven't discussed with your veterinarian. Examples included blistering an area that is actively healing or applying  shockwave to mask pain and then commence exercise.

Prevention and Training Tips
While stating there are many methods and opinions when it comes to training horses, Koenig offered a few common subjects backed by research. The first being the importance of daily turnout for young developing horses.  

Turnout and exercise
Many studies have looked at the quality of cartilage in young horses with ample access to turn out versus those without. It has been determined that young horses that lack exercise and are kept in a stall have very poor quality cartilage.
Horses that are started early with light exercise (like trotting short distances and a bit of hill work) and that have access to daily paddock turnout, had much better quality of cartilage. Koenig cited research from Dr. Pieter Brama and similar research groups.

Another study shows that muscle and tendon development depend greatly on low grade exercise in young horses.  Evaluations at 18 months of age found that the group that had paddock turnout and a little bit of exercise such as running up and down hills had better quality cartilage, tendon and muscle.  

Koenig provides a human comparison, with the example of people that recover quicker from injury when they have been active as teenagers and undergone some beneficial conditioning. The inference can be made that horses developing cardiovascular fitness at a young age stand to benefit their whole lives from the early muscle development.

Koenig says it takes six weeks to regain muscle strength after injury, but anywhere from four to six months for bone to develop strength. It needs to be repeatedly loaded, but one should not do anything too crazy! Gradual introduction of exercise is the rule of thumb.

Rest and Recovery
“Ideally they have two rest days a week, but one rest day a week as a minimum,” says Koenig. “I cannot stress enough the importance of periods of rest after strenuous work, and if you notice any type of filling in the joints after workout, you should definitely rest the horse for a couple of days and apply ice to any structures that are filled or tendons or muscles that are hard.” 

Not purporting to be a trainer, Koenig does state that two speed workouts a week would be a maximum to allow for proper recovery. You will also want to make sure they have enough access to salt/electrolytes and water after training.

During a post-Covid interview, Koenig imparted important advice for bringing horses back into work methodically when they have experienced significant time off.
“You need to allow at least a six-week training period for the athletes to be slowly brought back and build up muscle mass and cardiovascular fitness,” says Koenig.  “Both stamina and muscle mass need to be retrained.”

The importance was stressed to check the horse’s legs for heat and swelling before and after every ride and to always pick out the feet. A good period of walking is required in the warmup and cool down; and riders need to pay attention to soundness in the walk before commencing their work out.

Footing and Cross Training
With a European background, Koenig is no stranger to the varying track surfaces used in their training programs. Statistics suggest fewer injuries with horses that are running on turf. 

Working on hard track surfaces has been known to increase the chance of injury, but delving into footing is beyond the scope of this article.

“Cross training is very important,” says Koenig. “It is critical for the mental and proper musculoskeletal development of the athlete to have for every three training days a day off, or even better provide cross-training like trail riding on these days." 

Cross-training can mitigate overtraining, giving the body and mind a mental break from intense training. It can increase motivation and also musculoskeletal strength. Varied loading from training on different terrain at different gaits means bone and muscle will be loaded differently, therefore reducing repetitive strain that can cause lameness.

Hoof care
Whether it is a horse coming back from injury, or a young horse beginning training, a proficient farrier is indispensable to ensure proper balance when trimming the feet. In fact, balancing the hoof right from the start is paramount because if they have some conformational abnormalities, like abnormal angles, they tend to load one side of their joint or bone more than the other. This predisposes them to potentially losing bone elasticity on the side they load more because the bone will lay down more calcium on that side, trying to make it stronger; but it actually makes the bone plate under the cartilage brittle.  

Koenig could not overstate the importance of excellent hoof care when it comes to joint health and advises strongly to invest in a good blacksmith. Many conformational issues can be averted by having a skilled farrier right from the time they are foals. Of course, it would be remiss not to mention that prevention truly begins with nutrition. “It starts with how the broodmare is fed to prevent development of orthopaedic disease,” says Koenig. Consulting with an equine nutritionist certainly plays a role in healthy bone development and keeping horses sound.

Noel George and Amanda Zetterholm - The anglo-swedish duo taking French racing by storm

Article by Katherine Ford 

Training partnerships are now firmly established in racing. Father and son (or daughter), husband and wife, or experienced trainer and long-standing assistant; these entities are now regularly seen in Europe and beyond. The association of George & Zetterholm Racing, one of the newest names in the French jumps trainers’ column, doesn’t fit in any of the usual categories but has already proven its efficiency in less than a year of operation.
Twenty-four-year-old Noel George, who found his way to France during Covid, is a former amateur rider and the son of Gr. 1 winning British trainer Tom George; whereas dynamic Swedish-born Amanda Zetterholm boasts a wealth of experience in a variety of capacities in racing and bloodstock around the world. The pair have no background together, and a chance remark has seen them launch as one of France’s most exciting training operations. 

“We knew each other, but that was all; and it was (fellow Chantilly trainer) Tim Donworth who suggested we set up together,” explains Amanda. “Noel wanted to train in France, but of course it is complicated to set up here, so it was a good opportunity to do it in partnership. I told Noel I’d found this yard I love, so we went to visit it together, and he said he’d love to train here. I bought the yard exactly a year ago, in September 2022”.

Creating a masterpiece

Amanda and Noel each bring their own talents to the partnership, “I’m the Louvre, and he’s Thomas Gainsborough”! Amanda’s marketing background shines through with her metaphor illustrating that she provides the solid base for Noel to fulfil his role as “the artist” with the horses. 

Growing up in Sweden, Amanda Zetterholm enjoyed riding and show jumping but didn’t have any involvement in racing until studies took her to Australia, where she spent time with David Hayes and Matthew Ellerton. “My first job in racing was with agent Damon Gabbedy, who taught me a lot about the breeding side. Then I went to South Africa and spent three years with Mike de Kock, which was a great experience—between Dubai, England and South Africa. He is very avant-garde”.

In 2013, Amanda was recruited by the Aga Khan Studs as commercial executive and has fulfilled a variety of roles for the famous operation. She currently balances the burgeoning training career with work for the Aga Khan Studs but is soon set to devote herself fully to George & Zetterholm Racing. “I’ve spent 10 wonderful years with the Aga Khan Studs, but I will finish at the end of the year; I can’t do both. They’re very proud of what I’ve achieved”.

Add to these achievements a successful amateur riding career on the flat, a stint as Goffs French representative and an instrumental part in the setting up of the stable of former partner David Cottin, with whom she has two young sons, Winston and Clovis, plus success in buying young jumping stock to sell on, which has set her up financially to be able to buy the Chantilly yard; it is clear that Amanda is not shy of a challenge or a busy schedule. 

Well-defined roles

“We passed the trainers’ licence together, and the idea was always that Noel wanted to do his training regime. He’s on the track every morning with the horses. I’m out here maybe three times a week currently, but that will change once I finish with the Aga Khan Studs. We both discuss and do the entries. We’re on the same wavelength, and I would say I am a very easy partner. I have a lot of experience, and I don’t feel I have anything to prove.

“In France, there is so much paperwork. I deal with the business side, the staff and the logistics; and I do the communication with the owners, which I love. I don’t feel the stress that Noel feels with the owners as he is the one who has directly prepared the horse, so I can be more relaxed. I am there to reassure them and make sure that they have a good day out. We are very complementary. Noel is a very confident person. You need to be confident to be a good trainer because the horses feel the confidence, and the owners too. He passes that confidence on to everyone”.

Living the dream in France

Noel George displays a confidence which belies his years, and in France he has found an opportunity to fulfil a dream that he had not imagined possible. “Since I left school, I aimed to train flat horses because I didn’t see economically and business-wise how it could work training jumpers in the UK”. After a year with Graham Motion in the USA and summer holidays with Sir Mark Prescott and Joseph O’Brien, Noel George has learnt from some of the best on the flat. 

The French connection came about by coincidence, although there is family history across in Chantilly as father Tom George spent time with the pioneering François Doumen in the days of The Fellow, whetting his appetite for cross-Channel raids. “I remember when Dad always used to come over with runners and then Halley won the Gp. 1 Maurice Gillois. I wasn’t there that day but I remember it—Dad built his new kitchen because of it! That stuck in my mind, that the French prize money is amazing… I was meant to be going to Australia as an assistant, but then Covid happened and French racing started before anywhere else; so I moved over to work for Fabrice Chappet”.

Noel didn’t speak French when he arrived but learnt quickly—thanks to language apps, Chappet’s former assistant, and now young trainer Xavier Blanchet, as well as being motivated to communicate when chasing a few French girls!

During the period with Classic-winning Chappet, Noel oversaw a string of horses running under a provisional licence for his father Tom. “I was giving orders to Dad’s horses on the same gallops, and it was a help that I knew the farrier, the feed suppliers etc”.

Provisional training operations in France are restricted to three months, but the experience served to reiterate the financial sense of racing in France but also the accompanying bureaucracy.

“I eventually passed the trainers exams, which aren’t easy! It’s not just knowing the language, it’s knowing all the anatomy of the horse, in French, the employment laws, how to write a payslip—all the different taxes… For that, having Amanda is a huge asset because I can focus on training the horses and she does all that complicated stuff”.

Noel is also full of praise for his father Tom. “He’s a great source of advice for me; I ring him whenever I have a question. We couldn’t do it without him. He’s put his neck on the chopping block by pushing a lot of the horses over here, and it seems to be paying off”.

Top-class training grounds

Another huge advantage for George & Zetterholm Racing is their stable and accompanying facilities. The yard, on the outskirts of the village of Avilly-St-Léonard, has already sent out three winners of France’s feature Grand Steeple-Chase de Paris as former owner Christophe Aubert was responsible for Line Marine (2003) and Mid Dancer (2011 & 2012). 

This is part of France Galop’s huge Chantilly training domain, but being slightly out on a peaceful limb compared with the more famous locations of Chantilly, Gouvieux, Lamorlaye and Coye-la-Forêt, it has all the benefits of a private establishment. “We can’t praise France Galop enough for all they do for us,” says Amanda. “When the English owners come over, they just can’t believe it, and even Noel’s dad has his own amazing facilities; but he has to run it all himself. This area of Avilly has been almost dormant for several years and so the France Galop teams are very keen to revive it and make improvements”. 

In concrete terms, this means that Noel and Amanda, having the only active stable in the vicinity, have exclusive use of extensive schooling facilities and gallops. “We’ve got cross-country, steeplechase fences and hurdles. They are a little bit smaller than the racecourse ones, but I don’t think you have to jump big in the mornings. It’s better if they’re a bit smaller as they give the horses confidence. We tell the France Galop staff the days when we will be schooling and they make sure everything is prepared”.

Noel adds, “The training centre is incredible, and we are so well looked after by France Galop who really want to help us. They give the horses the best chance possible. We have a 2000m sand gallop through the forest, which we use daily; then there’s a big 2000m sand circle which isn’t watered but in the winter it’s very good for the youngsters—it’s like a racecourse! We have to go to Chantilly to use the grass, but I think it does the horses good to go on the lorry”.

Schooling is an integral part of training jumpers in France; and Noel admits, “I’ve watched videos of how Macaire and Nicolle do all the French schooling and we’ve mixed it with the English way; and it seems to be working”.

The French policy of regular schooling has been adopted, and here again, the French system offers benefits. “The likes of James Reveley, Felix de Giles, Nicolas Gauffenic, and Kevin Nabet will be in nearly every Wednesday. It’s not like in England where the jockeys might be riding up north or down south and are less available for schooling. The horses, especially the older ones over from England, love it. It gives them a change, especially with the different steeplechase obstacles like the bullfinch the bank, the white wall… And as we don’t have the hills they have in England, it is good for fitness”.

“The horses jump more in races here. In a two-mile hurdle in England, they jump eight small hurdles; whereas round Auteuil over two miles, they jump 12 mini-English fences. If you lose two lengths at a hurdle here, it makes such a big difference as the next hurdle comes much quicker than in England. Jumping is very important”.

Making financial sense

Jumping is important, but prize money is even moreso; and in less than a year of operation, the stable has already earnt plenty. “We’ve had 100 runners for 800,000€ in prize money, so that’s 8000€ per runner which is a great statistic. French racing is very lucrative,” says Amanda, while Noel emphasises the point further: “The very fact that a horse can be in training and not cost money is a huge benefit. The number of horses that pay for their training fees in England is very few; whereas if your horse isn’t paying your training fees here, you probably need to think about moving it on. It’s an incredible way to be and a massive advert for French racing. It just takes the pressure off everything”.

Capacity is maybe the only source of pressure currently for George & Zetterholm Racing. The yard has 25 boxes and 14 turn-out paddocks, with a further 15 boxes rented nearby and a barn with 16 more stables under construction at the yard. “We are limited in space, and we want to focus on quality rather than quantity,” says Amanda; although Noel’s ambitions have no limits. 

“The dream eventually would be to compete with the top trainers in the championship, but we want to race on both sides of the channel. I’m English. I’ve grown up in England, and we’ve got English owners; so our dream is to win big races in England too. I can’t see why we can’t do that training here. We have amazing grass gallops; we can do racecourse gallops at tracks like Compiègne, so we can get them as ready as anyone in England. Cheltenham is quicker to access for us on the lorry than it is for Gordon Elliot and Willie Mullins; and Kempton is closer to us than Pau”!

Again, the support from Tom George will be key, as horses will spend a few days at his Down Farm in Slad near Cheltenham to acclimatise and school over British obstacles. 

“I can understand why Britain is not a priority for many French trainers, as there is so much money to be won here; but we have owners that are buying horses to win on big days and they want to win at the big meetings. When we do get on the boat, hopefully we will bring a few winners back for France, with English owners and English and Swedish trainers”! 

Lower limb anatomy and how it can be conditioned for racing

Article by Adam Jackson MRCVS 

Better understanding the appropriate levels of exercise and training while the horse’s body grows and develops has been a topic of research for many years. Although it has been shown that young, growing horses are well-suited to adapt to conditioning, it is vital that continued research is performed in order to develop thoughtful and strategic training methods to promote healthy, fit and sound horses with long careers and lives.  

Horses’ limbs consist of dozens of muscles, bones, tendons, ligaments, and joints that allow the horse to move as well as support its body weight. The limbs function to provide thrust and movement while absorbing impact and bearing weight.  Most of the horse’s weight is supported by the fore limbs, while the propulsion of the horse is provided by the hind limbs. In addition, the horse has two apparatuses referred to as the stay apparatus and suspensory apparatus. The stay apparatus allows major joints in the limbs to lock so that the horse may rest and relax while standing. The suspensory apparatus is designed to absorb shock, carry the horse’s weight, and prevent the overextension of joints. Finally, the hooves are important structures that maintain support and traction as well as provide additional shock absorption.  

Since the cardiovascular system provides blood supply throughout the body, by responding to various stimuli, it can control the velocity and amount of blood carried through the vessels, thus, delivering oxygen, nutrients, hormones, and other important substances to cells and organs in the body.  It plays a very important role in meeting the body’s demands during exercise, stress, and activity.  

Exercise is used to increase the body’s ability to withstand repeated bouts of similar exercise with less impact.  With a strong and healthy cardiovascular system, there is an improved ability of the musculoskeletal system receiving oxygen, thus, allowing muscles to better their capacity to use oxygen and energy.  However, the adaptation period for each of these physiological systems do differ as the cardiovascular system adapts faster compared to the musculoskeletal system. This is often an overlooked consideration when developing training programmes for horses. 

It is important to understand the various functions, structures, and adaptive processes of the horse’s musculoskeletal system such as bone, articular cartilage, tendons, and ligaments in order to develop appropriate training regimens. 

Bone has many important roles that involve locomotion, the storage of minerals (especially calcium and phosphate), soft tissue and vital organ protection, and the support and containment of bone marrow. Bone is a specialised connective tissue, and together with cartilage forms the strong and rigid endoskeleton.  The bone is continuously altering through two processes called bone modelling and bone remodelling, involving four cells referred to as osteoclasts, osteoblasts, osteocytes and bone lining cells.  

Osteoblasts secrete bone matrix in the form of non-mineralised osteoid, which is then mineralised over a few weeks to form a bone matrix.  Osteoclasts are involved in resorption of bone as this process occurs faster than the formation of bone. When the bone surfaces are not in the development or resorption phase, the bone surface is completely lined by a layer of flattened and elongated cells termed bone-lining cells.  Osteocytes are derived from osteoblasts and are highly specialised to maintain the bone matrix.  They are designed to survive hypoxic conditions and maintain biomineralisation of the bone matrix.  Osteocytes also control osteoblastic and osteoclastic activities allowing bone remodelling.

The function of bone modelling is to alter and maintain shape during growth. As the horse grows and develops, bone modelling occurs with the acquisition and removal of bone.  While the young horse grows and develops, bone modelling allows the bone to endure strains from everyday work and exercise. The adult skeleton undergoes a minimal amount of bone modelling. Due to the presence of the high frequency of bone modelling in young horses, their skeletal strength is highly influenced by strains to their bones during exercise and daily use. With this knowledge, it has been concluded and confirmed that short-term dynamic exercise of an adolescent can lead to beneficial changes to its bone morphology.  

Bone remodelling is a different process, in which old and damaged bone is renewed, which enables the bone to respond and adapt to changing functional situations. Bone remodelling is usually a coordinated relationship between bone resorption and bone formation. This process occurs throughout the horse’s life with the renewal of primary, damaged or old bone. Osteoclasts absorb old and damaged bone, and the osteoblasts form new bone and lay down new bone matrix until the earlier absorbed bone is replaced. In those animals with musculoskeletal disease or damage, there is an imbalance of osteoblast and osteoclast activity. With the knowledge that osteoblast activity to make new bone takes months whilst osteoclast activity of removing old and damaged bone only takes a few days to two weeks, bone that is being repaired is at a high risk of further injury as bone removed has not been completely replaced.   Multiple studies have shown that exercise while growing can provide lifelong benefits; however, it must be done with care and knowledge.

In addition, many studies have shown that exercise of a dynamic nature in moderate distances, such as that achieved in the pasture or prescribed short-distance high-speed work is beneficial to musculoskeletal development and may prevent injuries when entering race training. It has also been observed that long slow work does not increase bone strength. Below is a summary of the young horse response of the various types of exercise.

Articular cartilage is a highly specialised connective tissue found in joints with the role of providing a smooth, lubricated surface of articulation and to help transmit loads with a low amount of friction. The articular cartilage is a hyaline cartilage (flexible and strong tissue providing a smooth, slippery surface) with a dense “ExtraCellular Matrix” (ECM) consisting of specialised cells called chondrocytes, collagen and proteoglycans. These components help to retain water in the ECM that is required for the joints mechanical properties. As age increases, hydration of the matrix does decrease, resulting in stiffness. Chondrocytes are residential cells in articular cartilage that play a role in the development, maintenance, and repair of the ECM. They do respond to a variety of stimuli, including mechanical loads, growth factors, hydrostatic pressures, piezoelectric forces (formation of electric charge with force). Because of the lack of blood vessels, lymphatics, and nerves as well as being a harsh biomechanical environment, there is a limited capacity to heal and repair. In addition, chondrocytes have limited potential for replication, thus, have limited healing capacity; and chondrocytes survival depends on an optimal chemical and mechanical environment.  

Maintaining joint health is vital, which requires the preservation of healthy cartilage tissue. Inactivity of joints is detrimental to articular cartilage; thus, regular movement of joints and dynamic loads is needed to provide a normal articular cartilage structure and function. Biochemical responses of the cartilage to exercise are not nearly as well known compared to bone. While the confinement of young horses stunts joint development, excessive straining of cartilage can also reduce joint development. It has been observed that pasture access was optimal for the development of joints and the confinement or excessive sprint exercise (12–32 sprints of 40 metres for 6 days a week for 5 months) causes detrimental effects on the joint and may be deemed as unnatural exercise.  It is also thought that exercise is needed well before two years of age to allow cartilage thickening as well as the avoidance of confinement. It can be concluded that further studies are required with respect to level of exercise and type of exercise in order to achieve healthy cartilage tissue as there is clearly a fine line between frequency and intensity of exercise.  

Tendons and ligaments are distinct but closely related tissues that have unique and important roles in musculoskeletal function and musculoskeletal disease. Tendons and ligaments are dense, fibrous connective tissues that connect muscle to bone or bone to bone, respectively.  These tissues transmit mechanical forces to stabilise the skeleton and allow body movement.  Tendons and ligaments consist mainly of collagen type I as well as small amounts of collagen III, IV, V, and VI. There are also various proteoglycans in tendons and ligaments that both organise and lubricate collagen fibre bundles. The elasticity of tendons and ligaments is due to the large amount of type I collagen. During locomotion, the tendon decreases energy cost to the horse by acting as a spring to store and release energy while stretching and recoiling in the stance and swing phases of each stride. Tendons and ligaments have blood vessels and nerves that allow the homeostasis and response to injury.  

Tenocytes are tightly regulated by a series of growth factors and transcription factors that allow the synthesis, maintenance, and the degradation of the tendon extracellular matrix. Tendons are elastic, but tearing may occur if there is excessive loading on the tendon and the repair of collagen is a slow process. In addition, tendons have crimp morphology where the tendons buckle in a state of relaxation and act as shock absorbers.  Unbuckling of the tendon occurs during loading.  This crimp morphology may be disturbed if an injury occurs and also is reduced in older horses.  

Due to the variation of activity of tenocytes in foals and young horses, it has been observed that both a lack of exercise and excess of exercise can impair tendon make-up and subsequent functionality. With the current data and research that has been gathered, it can be concluded that if horses take advantage of spontaneous exercise when in the paddocks (which they often do), the developing tendons may benefit and be at a lower risk of injury when racing training starts. 

Conclusion

It is clear that further research is needed in order to ascertain the optimal amount and type of exercise that is needed in order to provide a strong musculoskeletal system and functional performance. However, it has been shown that prescribed exercise during the growth of the horse can increase the longevity of the horse’s health and performance. It has been observed that confinement and the lack of loading can result in weaker tissues and the loss of function of none, tendons, ligaments and articular cartilage.  However, it must also be recognised that medical attempts to alleviate pain so that a horse can continue to train through an injury can greatly increase tissue damage which is detrimental to the horse’s health and career. It is far more beneficial to provide an adequate amount of time for the injury to heal, thus, putting the horse’s health and wellbeing as a top priority.  

Nutritional Perspective

Bone development in yearlings from the sales ring to racing

Article by Des Cronin B.Ag.Sc, MBA

Maintaining the equine skeleton is vital to ensure optimal development of the young growing horse, minimise risk of injury in the performance horse, and promote longevity and soundness.

The skeletal development and health of a young horse begins in utero and ensuring the broodmare receives the correct intake of key nutrients will be critical to the growth of the unborn foal. Producing high-quality milk places a significant drain on the mineral reserves of the mare. Maintaining mineral intakes during peak lactation is vital to ensure the foal receives the best nutrition to support the rapid skeletal development in the early weeks and months of growth. During this time, bone formation, body size, and muscle mass greatly increase. Risk of defective bone and related tissue formation increases with one of more of the following:

• Poor diet with the incorrect balance of energy and nutrients in the daily ration

• Inadequate amounts of calcium (Ca) and phosphorus (P)

• A reversed Ca:P ratio

• Low zinc (Zn) or copper (Cu) in the diet

• Low Vitamin D

Feeding a young horse for a maximum growth rate is undesirable because bone hardening lags greatly behind bone lengthening. At 12 months old, the young horse could reach about 90 to 95 per cent of its mature height but only about 75 per cent of its mature bone mineral content.

Ideally, young horses should gain weight at a rate that their developing bones can easily support. Growing bones and connective tissues don’t have the strength to support rapid weight gain from overfeeding, especially energy. Rapid weight gain can also make other skeletal anomalies worse. In these cases the risk of developmental orthopaedic disorders (DOD) and unsoundness increases.

DOD and unsoundness can also occur during uneven growth. For example, switching an underfed, slow-growing horse to a good diet that allows quick growth (compensatory growth), increases the risk of DOD. Foals between the ages of 3 and 9 months of age are at greatest risk of DOD.

Fresh forages, for example grazed grass, usually provide enough major minerals such as calcium (Ca) and phosphorus (P) for the growing horse. However, there can be significant variation in calcium and phosphorus levels in all forages but particularly preserved forages (hay and haylage). Forage analysis should always be undertaken to determine mineral composition. 

For young fast-growing horses, the diet must supply the quantities of calcium and phosphorus needed for normal bone formation. In terms of Ca:P ratio, the ratio must be positive in favour of calcium. Horses are much more tolerant of high-dietary calcium than other species. For practical purposes, a good guideline would be to keep the ratio Ca:P between 1.5 to 1 and 2.5 to 1.  Grains (e.g., oats) contain 10 per cent of the calcium level found in typical forages. Grains are poor sources of calcium, both in terms of the amount of calcium supplied and their effect on Ca:P ratio in the diet. Where grains are fed, supplementation will be necessary to balance the diet.  

While some forages may contain adequate calcium and phosphorus, they will typically supply less than 20 per cent of the daily requirements for trace elements. Supplementation of trace elements will generally be necessary to support normal bone development.

Where concentrates are fed (especially low levels), supplementation may still be necessary to balance the overall mineral and trace element intake. Nutritional advice should be sought to ensure the horse's diet is correctly balanced.

To meet the carefully balanced requirements of key minerals, it is advisable to supplement the daily rations of growing horses and young horses entering training with an appropriate nutritional product. 

Make sure that the supplement used contains the correct ratio of calcium and phosphorus, as well as other key nutrients such as vitamin D and chelated trace elements (copper, manganese, and zinc) to support normal bone development.

Supplementing branch chain amino acids in the diet ensures that growth is maintained. Lysine plays a key role when protein concentrations in the body are low. Vitamin A supports collagen formation, which is a key component of the supportive structures of joints (tendons and ligaments). Vitamin D3 is added to enhance calcium absorption.

Although growth rates slow after the age of two, they are still juvenile in their skeletal development with some growth plates, such as the shoulder and stifles, yet to completely close. Although they may look like fully grown adults, it is still important to meet nutritional requirements especially if starting training and work. With the addition of exercise and training, a young horse's nutritional needs change.  The added forces from groundwork on the long bones and increased requirements of other nutrients like electrolytes need to be considered. 

Finally, horses all grow and develop at different rates because of factors such as genetics. Some youngsters will need  more support for longer periods of time than others, so it is important to manage accordingly.

Who should be dictating the Rules of Racing - the racing industry or government?

Article by Lissa Oliver

Regular readers of this publication will already be well aware of racing’s social licence and the efforts required to ensure the sport’s popularity with the public and, essentially, the wellbeing of our participants. EU legislation is increasing in strength in addressing equine welfare in general, but in Germany in particular, laws coming down from the government are impacting many racing yards. 

The law introduced last year regarding minimum paddock time for all horses is one such notable problem. As Belgian trainer Guy Heymans points out, “Turnout for horses every day is not the same as the requirement for horses to remain in paddocks. If I understand correctly, the demand is not just turnout; they mean that the horses are in a paddock for a certain period of time every day. It’s OK for me, but a trainer with 20 horses or plus in training will probably not have enough paddocks, and it is difficult to keep such a horse in shape. Of course it is a plus for horses to spend a short time in the paddock, but when they demand horses stay permanently in paddocks, it is impossible to bring a horse to top form.” 

Not every trainer may agree with that, and some have enjoyed great success ‘training from the field’, but it is a matter of personal choice and methods, as well as having the luxury of such choice. It isn’t so much about making our own decisions on equine welfare in particular, which we would all prefer to embrace as much as we can; but it’s more about the practical ability to do so and the apparent gulf between those setting the rules, and now laws, and those who have to apply them in daily practise. 

“There are some countries lagging a bit behind in welfare, and I would be happy to see more legislation coming in,” says Irish trainer Amanda Mooney. “We just have to learn to adapt and work with it. Sweden has a very high standard of welfare and a very good aftercare service. Horses aren’t just sold on and rehomed; they’re put out on loan—the same as the Godolphin Lifetime Care programme. I think more could be done for aftercare.”

Germany has the strictest animal welfare legislation worldwide and is the only country in the EU to have integrated animal welfare into its constitution. German law could be the crystal ball into the rest of European racing’s future. In 2018, horses were no longer allowed to run in a tongue-tie, as a result of animal welfare concerns. Rüdiger Schmanns, director of racing for German Racing, said at the time, "In all other equestrian sports in Germany the use of tongue-ties is banned—racing was the last equine sport which allowed tongue-ties. With growing animal welfare activities, especially in Germany, there was no possibility of allowing the use of tongue-ties to continue."

This year, stricter whip rules were adopted; and any jockey who uses the whip six times in a German horse race could expect an 84-day ban under the new penalty system. The number of strokes of the whip allowed per race has been cut from five down to three, and the length of bans for going more than one over the limit can now be measured in weeks and months, rather than days.

 “This looks extreme but will hopefully not occur,” said Rüdiger Schmanns. “The animal health pressure is high in Germany. We would like to have harmonised rules regarding the whip at least in the whole of Europe, but that seems to be a long way off as the differences in England and Ireland compared to France and Germany are still quite big.”

At least those rules are coming down from racing’s governing bodies, assisted by Boards of selected professionals representing all industry stakeholders. In theory, the Rules of Racing should be a suitable compromise agreed by all for the betterment and progression of the sport. But what happens when Rule changes have not involved industry stakeholders? When changes come from government level they may not always be the desired result of consultation with racing’s professionals. 

The Rules of Racing have historically been set down by industry participants to govern the sport in a fair manner. The earliest known example is quite literally set in stone and dates to the earliest part of the first century, some 2,000 years old. Professor Hasan Bahar’s 2016 discovery at an ancient Roman racecourse in Turkey—the oldest existing tablet describing the rules of horseracing—illustrates a keen sense of fairness in the sport. Prof. Bahar points out, “It says that if a horse comes in first place in a race, it cannot participate in other races.” A winning owner was also forbidden from entering any other horses into an event’s subsequent races, presumably to give others a chance at glory, Prof Bahar suggests. “This was a beautiful rule, showing that races back then were based on gentlemanly conduct.”

It also highlights the origins of the sport’s governance, replicated in Britain by the next earliest-known Rules of Racing set by The Jockey Club in 1750. The Rules were dictated by racehorse owners to preserve and progress their racing and breeding interests. Even prior to a rule book, in 1664, it was King Charles II who personally wrote The Rules of the Newmarket Town Plate. According to Whyte's History of the English Turf (1840), King Henry VIII passed a number of laws relating to the breeding of horses. Racing was a self-governing institution, more to the point, one governed by racehorse owners.

Nevertheless, governments haven’t always been keen for that arrangement to continue. The British Jockey Club was formed in 1750, specifically to create and apply the Rules of Racing in the wake of a decade of Parliamentary opposition to the sport. There are few racing nations left where the original governance of a Turf Club or Jockey Club hasn’t transitioned into a State-funded corporate body.

Parliamentary opposition to the growth of horse racing in the 1740s focused on the damaging effect of gambling. Three hundred years on, no other sport has entangled itself so constrictively with gambling. Racing’s economy is no longer based on the revenue of racehorse owners, and the sport is answerable to the holders of the purse strings.

While researching a quote from former Member of Parliament Sir Clement Freud, who claimed that “horse racing is organised purely to generate taxes,” the transcript of an interesting House of Lords debate surfaced. Though dated February 1976, the facts, figures, and sentiments quoted could as easily place it in 2023, which makes for a sorry commentary on British racing.

The establishment of a Royal Commission on Gambling led to Sir Clement Freud remarking on the “large number of otherwise non-viable racecourses kept open to ensure sufficient races being run, even as the financial rewards to the owners and trainers declined to the point where most could barely cover their expenses.”

During the House of Lords’ debate on the matter, Lord Newall observed, “The income from betting is believed to reach the optimum level with two meetings every day with staggered starting times. After this, the same money apparently chases after more horses.” And perhaps initiating an argument that continues to this day, Lord Gisborough pointed out, “There has been, and often is, criticism of the value of the Pattern race prizes, but these few races at the top of the pyramid of racing are the necessary incentives to encourage breeding of the best animals, the very capital of the industry. It would not help racing in the long run if the value of the Pattern prizes were to be spread over the rest of racing. They provide the vital opportunity for the best horses of the world to be matched together, without which the best British horses would have to race more abroad to prove their value for breeding purposes.”

Perhaps we digress here, but the relevant points of 40 years ago, 300 years ago and, indeed, 2,000 years ago are summed up by The Lord Trevethin Oaksey, who explained, “What you need is honourable, fair-minded, unbiased men who are answerable to nobody but themselves, and who have as much experience as possible of the problems involved.”

And therein lies the modern problem, with racing dependent upon gambling revenue and accountable to the betting operators and the taxpayer. Self-governance is fast becoming a thing of the past, but the bigger problem is being given the necessary time and finances to adapt.

In our 2021 winter issue, German trainer Dominik Moser warned, “We have so many new rules and many more rules being introduced for next year. All horses must spend a number of hours out in the paddock each day, and they must be assessed by a vet before going into training. I have paddocks for my horses, but I don’t currently have enough for all of them to be out every day, so I have to build more paddocks. My aim is that all of my horses will be able to go out from after they have finished training at 1pm until the evening. The training centres, such as Cologne, will have a big problem, because there is not enough space for the number of paddocks needed. 

“These rules are coming directly from government, not from Deutscher Galopp. I like that we think more about the horses; we have recently been thinking more about the people, the jockeys and staff. The horse had stopped being our number one concern. This is the right way, but the rule is not easy to adapt to; we haven’t been given time to prepare.”

Christian von der Recke agrees wholeheartedly with the reasoning behind the legislation and tells us, “From day one, our horses go to the paddock; and I am sure that is part of the success. They enjoy more variety and have less stomach ulcers. More exercise is the key to success.” However, von der Recke has a large private facility at his disposal, with ample paddock space, denied to those trainers based at training centres. 

One such centre is Newmarket, where John Berry reasons, “It's clearly preferable to turn one's horses out for part of the day rather than have them confined in their boxes for 23 hours a day or more; but some people prefer not to do so, often because of not having either the time nor the space to do so. Just common sense says it's better for them mentally, and physically too; but each to his own.

“I'd actually regard not gelding horses as a far bigger concern as regards horses' mental well-being than lack of freedom, but that's by the by. Obviously, some colts have to remain colts to ensure the survival of the species, but only a tiny percentage are required for stud duties; and keeping the others as colts rather than gelding them is just nuts. Sexual frustration must be at least as great a cause of anguish for horses as frustration at lack of liberty. 

“I'd have thought if a government wanted to do something to increase the sum of equine happiness, addressing this issue might be more appropriate, but obviously it would be hard to frame the laws satisfactorily.

“Obviously in utopia every horse would have access to freedom and to companionship (although the latter isn't always a good idea with colts), but life isn't utopian. Similarly, it would clearly be a good idea if every dog could have a life where he can have a run off the lead every day, every school would have good sports facilities, and every community would have good recreation and leisure facilities. But we can't even manage to achieve that with humans, so I'd be surprised if the government thought that this was a worthwhile way to direct its energies.”

British government’s current distraction is reforming gambling legislation, which is creating anxiety and even panic among the racing community. Once again, it’s social licence and a need to enforce ‘protection’ that attracts government attention, with affordability checks upsetting punters and threatening horse racing's revenue.

In Ireland, that same focus is the driving force behind the Gambling Regulation Bill, which proposes a ban on televised gambling advertising between 5.30am and 9pm, which of course affects a large portion of advertising on live horse racing coverage. As a result, Racing TV and Sky Sports Racing have threatened to pull their racing coverage in Ireland, stating that their service will become "economically unviable.”

This no longer comes down to welfare or integrity within the sport. Do we protect the vulnerable or protect our own interests, even in the knowledge our interests conflict? We may try to excuse our decision, but further down the line, as more attention is put on the sport, will we really be able to defend our corner?

Ryan McElligott, CEO Irish Racehorse Trainers Association, announced in reaction to the bill, "If Racing TV determined it was no longer viable to broadcast in Ireland, then Irish racing disappears off our screens. That would be detrimental to the whole industry. 

"There are plenty of owners who don't get to go racing as much as they would like, but it's very easy to watch their horses run should they not make it. If you take that away, I think that would put a huge dent in the sport's appeal and also demand from an owner's point of view. It would put us at a huge disadvantage when compared to other jurisdictions.

"We're talking about subscription channels, and it is a requirement that you are over the age of 18 to buy a subscription to a package like Racing TV. These dedicated racing channels exist behind a paywall, so there is already a safeguard there.

“Every facet of the industry is wholly supportive of gambling regulation which protects vulnerable people. This is not a deliberate move to damage the sport; this would be an unintended consequence. It is hugely concerning for the industry."

In Britain, owners have already very publicly left the game as a result of the Gambling Act Review White Paper financial risk checks. All betting operators have a social responsibility to create a safe environment, and how much money a client can afford to spend on gambling is a key part of the safe environment.

Secretary of State for Culture, Media and Sport, Lucy Frazer KC, described the White Paper as “consumer freedom and choice on the one hand, and protection from harm on the other” while stating in the House of Commons in April: “With the advent of the smartphone, gambling has been transformed: it is positively unrecognisable today, in 2023, from when the Gambling Act was introduced in 2005. Temptation to gamble is now everywhere in society, and while the overwhelming majority is done safely and within people’s means, for some, the ever-present temptation can lead them to a dangerous path. When gambling becomes addiction, it can wreck lives: shattered families; lost jobs; foreclosed homes; jail time; suicide. These are all the most extreme scenarios, but it is important to acknowledge that, for some families, those worst fears for their loved ones have materialised. Today we are bringing our pre-smartphone regulations into the present day with a gambling White Paper for the digital age.”

More and more, we can expect legislation to encroach on the racing industry and force us to face moral dilemmas. Racing jurisdictions are doing their best to be seen by the public to be doing their best for equine welfare. Currently, Ireland has a very basic 28-page “Our Industry, Our Standards” guide to equine welfare; France has a very comprehensive 139-page “Charter for Equine Welfare,” based upon the official EU Paper; Germany has a 44-page “Animal Welfare in Equestrian Sport Guideline”; and Britain has “A Life Well Lived,”—a 130-page welfare strategy. Sweden, renowned throughout other racing nations for its top-class welfare, relies on a website to provide current guidelines and information. 

The EU Discussion Paper on Equine Care, adopted so well by France Galop in its charter, has multiple language versions and informative images, making it a simple solution for those countries lagging behind. It is also of visual appeal to those outside of the sport seeking reassurance. We may not consider them to be relevant, but they are proving to be the most important players in rulemaking.

TopSpec Trainer of the Quarter – Stuart Williams

Article by Lissa Oliver

“A conjurer of a trainer. One who can transform an apparently moderate animal into a frequent winner.” Thus quoted Timeform, and we can only concur as we award our TopSpec Trainer of the Quarter to Newmarket-based Stuart Williams for a truly remarkable upgrade of the Godolphin cast-off, Quinault.

Joining Williams from Charlie Appleby in February this year, the three-year-old gelding had only one previous run to his name, when finishing last in a 2022 novice race. Quinault’s first run for Williams saw him place third and earn an official rating of 47. His record for 2023 now reads an impressive seven wins from 10 starts to date, including a straight run of six wins in handicap company, which took him to the brink of an historic record, hardly disappointing when breaking the run with a third in the Shergar Cup Sprint at Ascot. However, it was back at Ascot that Quinault did manage his seventh win in the bet365 Handicap in September, taking his official rating to 97.

“I’m pleased to say he has come out of the race in good form. He’s a very tough horse, and he’s got loads of talent as well,” says Williams, singling out apprentice jockey Luke Catton as instrumental in his development. “Luke has done a fantastic job settling him. The horse was just a runaway when he arrived—he would just bolt. 

“We trained him on a treadmill for the first two months—so he never left the yard—before we slowly started to introduce him to Newmarket Heath. There’s a lot of work gone into him. 

"He’s always had talent; it’s just been a case of letting the horse know it and letting him use it. He’s always been fast, and he’s bred to get further; so as long as we can keep him settled in his races, that’s a route we’ll look to go with him. He's fairly straightforward to ride—he just jumps and goes.”

Williams, who took out his licence in 1993, is based on Hamilton Road in Newmarket, conveniently backing onto the racecourse side training grounds. Diomed Stables has 72 boxes, including 60 newly refurbished American barn-style boxes with climate control and six grass turnout paddocks. Williams also has a sand ride for light exercise of his horses, as well as an equine solarium.

He is a great believer in the benefits of swimming, and his horses use the nearby equine swimming pool on a regular basis to help improve fitness without putting excessive strain on their legs.

Williams has been involved in racing since he was a child—his father having been a jockey, and in his formative years worked for Bill O’Gorman, Ron Sheather and Alex Scott, as well as Bart Cummings in Australia. He also spent time working in France and Norway before taking out his own licence. In 2011, he received what he acknowledges as ‘the highest recognition’ from his peers when he was voted president of the National Trainers Federation.

Williams feels it might now be time to step Quinault up to stakes company after his latest win; and the once 47 to now 97 rated gelding certainly gives the impression there’s plenty more to come.

Dangers of inbreeding and the necessity to preserve sire lines in the thoroughbred breed

Inbreeding is the proportion of the genome identically inherited from both parents.

Inbreeding coefficients can be estimated from pedigrees, but pedigree underestimates the true level of inbreeding. Genomics can measure the true level of inbreeding by examining the extent of homozygosity (identical state) in the DNA of a horse. A mechanism to examine genomic inbreeding for breeding purposes has yet to be developed to be used by all breeders but once available, it must be considered as a tool for breeders.

Breeding of potential champion racehorses is a global multi-billion sterling or dollar business, but there is no systematic industry-mediated genetic population management.

Inbreeding in the modern thoroughbred

The thoroughbred horse has low genetic diversity relative to most other horse breeds, with a small effective population size and a trend of increasing inbreeding.

A trend in increased inbreeding in the global thoroughbred population has been reported during the last five decades, which is unlikely to be halted due to current breeding practices.

Ninety-seven percent of pedigrees of the horses included in a recent study feature the ancestral sire, Northern Dancer (1961); and 35% and 55% of pedigrees in EUR and ANZ contain Sadler’s Wells (1981) and Danehill (1986), respectively.

Inbreeding can expose harmful recessive mutations that are otherwise masked by ‘normal’ versions of the gene. This results in mutational load in populations that may negatively impact on population viability.

Genomics measured inbreeding is negatively associated with racing in Europe and Australia. The science indicates that increasing inbreeding in the population could further reduce viability to race.

In North America, it has been demonstrated that higher inbreeding is associated with lower number of races. In the North American thoroughbred, horses with higher levels of inbreeding are less durable than animals with lower levels of inbreeding. Considering the rising trend of inbreeding in the population, these results indicate that there may also be a parallel trajectory towards breeding less robust animals.

Note that breeding practices that promote inbreeding have not resulted in a population of faster horses. The results of studies, generated for the first time using a large cohort of globally representative genotypes, corroborate this.1,3

Health and disease genes

It is both interesting and worrisome to consider also that many of the performance-limiting genetic diseases in the thoroughbred do not generally negatively impact on suitability for breeding; some diseases, with known heritable components, are successfully managed by surgery (osteochondrosis dessicans, recurrent laryngeal neuropathy, for example), nutritional and exercise management (recurrent exertional rhabdomyolysis), and medication (exercise induced pulmonary haemorrhage). This unfortunately facilitates retention of risk alleles in the population and enhances the potential for rapid proliferation of risk alleles if they are carried by successful stallions.

Types of inbreeding

Not all inbreeding is bad. Breeders have made selections for beneficial genes/traits over the generations, resulting in some inbreeding signals being favoured as they likely contain beneficial genes for racing. Importantly, examination of a pedigree cannot determine precisely the extent of ‘good’ and ‘bad’ inbreeding. This can only be determined from DNA analysis.

Historic inbreeding (arising from distant pedigree duplicates) results in short stretches of DNA identically inherited from sire and dam. 

• This may be considered ‘good’ inbreeding.

• It has no negative effect on racing.

• The horse may be carrying beneficial mutations that have been maintained from distant ancestors through breeders’ selection.

Recent inbreeding (arising from close pedigree duplicates) results in long stretches of DNA identically inherited from sire and dam. 

• This may be considered ‘bad’ inbreeding.

• It is negatively associated with racing.

• The horse may be carrying harmful mutations that have not yet been ‘purged’ from the population.

Obviously, in terms of breeding, it’s always possible to find examples and counterexamples of remarkable individuals; but the science of genetics is based on statistics and not on individual cases.

Sire lines

Analysis of the Y chromosome is the best-established way to reconstruct paternal family history in humans and animal species. The paternally inherited Y chromosome displays the population genetic history of males. While modern domestic horses (Equus caballus) exhibit abundant diversity within maternally inherited mitochondrial DNA, until recently, only limited Y-chromosomal sequence diversity has been detected.

Early studies in the horse indicated that the nucleotide variability of the modern horse Y chromosome is extremely low, resulting in six haplotypes (HT). However, this view has changed with the identification of new genetic markers, showing that there is considerably more genetic diversity on the horse Y chromosome than originally thought. Unfortunately, in thoroughbreds, the male gene pool is restricted, with only three paternal lines remaining.

The Institute of Animal breeding and genetics of the Veterinary Medicine School at Vienna applied fine-scaled Y-chromosomal haplotyping in horses and demonstrated the potential of this approach to address the ancestry of sire lines. They were able to show the microcosmos of the Tb-clade in the thoroughbred sire lines. 

It is interesting to note that more than half of the domestic horses in the dataset (76 of 130) have a Y chromosome with a thoroughbred ‘signature’. These includes thoroughbreds, standardbreds, many thoroughbred-influenced breeds (warmbloods, American quarter horses, Franches-Montagnes, a Lipizzan stallion and the Akhal-Tekes).

The General Stud Book shows that thoroughbred sire lines trace back to three founding stallions that were imported to England at the end of the 17th century. 5 Now, the heritage of the thoroughbred sire lines can be better understood using Y chromosome information. It is now possible to clearly distinguish sublines of Darley Arabian, born in 1700 (Tb-d) and Godolphin Arabian, born in 1724 (formerly Tb-g, now Tb-oB3b). The third founder, Byerley Turk, born in 1680, was characterised by the Tb-oB1 clade. According to pedigree information, only few of the tested males trace back paternally to Byerley Turk, which are nearly extinct.

There are now 10 different Y chromosome sub-types known in the thoroughbred. Two come from the Godolphin Arabian, five come from Byerley Turk, and three come from Darley Arabian.

Even if genetic analysis shows that there was an error in the stud book recording of St Simon’s parentage and that horses descending from St Simon should be attributed to the Byerley Turk lineage, probably 90% of the current stallions are from the Darley Arabian male line. So, there is a true risk that we could lose a major part of the Y chromosome diversity.
Conclusions and solutions

We should do everything we can to ensure that thoroughbreds are being sustainably bred and managed for future generations. With the breeding goal to produce viable racehorses, we need to ask ourselves, are we on track as breeders? 

If inbreeding is negatively affecting the chances of racing and resulting in less durable racehorses, will this continue to affect foal crops in the future? How can we avert the threat of breeding horses that are less able to race? If the ability to race is in jeopardy, then is the existence of the thoroughbred breed at risk? 

International breeding authorities are studying the situation and thinking about general measures allowing the sustainability of the breed.

Breeders

What can individual breeders do to produce attractive foals that are safe from genetic threats? How do you avoid the risk of breeding horses that are less fit to race? 

There is no miracle recipe, and each breeder legitimately has his preferences.

An increasingly important criteria for the choice of a stallion is his physical resistance and his vitality, as well as those of his family. It is often preferable to avoid using individuals who have shown constitutive weaknesses, or who seem to transmit them.

The use of stallions from different male lines can make it possible to sublimate a strain and better manage the following generations. The study of pedigrees must exceed the three generations of catalogue pages.

In the future, genomics—the science that studies all the genetic material of an individual or a species, encoded in its DNA—will certainly be able to provide predictive tools to breeders. This is a track to follow.

Trainers

Trainers should be aware of the danger of ‘diminishing returns,’ where excessive inbreeding occurs. Today, when animal welfare and the fight against doping are essential parameters, it is obvious that trainers must be aware of the genetic risks incurred by horses possibly carrying genetic defects.

Together with bloodstock agents, trainers are the advisers for the owners when buying a horse. Trainers already know some special traits of different families or stallions, but genomic tools might become essential for them too.

Air Quality and Air Pollution’s Impact on Your Horse’s Lungs

There’s nothing like hearing a horse cough to set people scurrying around the barn to identify the culprit. After all, that cough could mean choke, or a respiratory virus has found its way into the barn. It could also indicate equine asthma. Yes, even those “everyday coughs” that we sometimes dismiss as "summer cough" or "hay cough" are a wake-up call to the potential for severe equine asthma. 

Formerly known as heaves, broken wind, emphysema, chronic obstructive pulmonary disease (COPD), or recurrent airway obstruction (RAO), this respiratory condition is now called severe equine asthma (sEA). These names reflect how our scientific and medical understanding of this debilitating disease has changed over the years. We now consider heaves to be most comparable to severe asthma in people.

But what if your horse only coughs during or after exercise? This type of cough can mean that they have upper airway irritation (think throat and windpipe) or lower airway inflammation (think lungs) meaning inflammatory airway disease (IAD), which is now known as mild-to-moderate equine asthma (mEA). This airway disease is similar to childhood asthma, meaning  that it can go away on its own. However, it is still very important to call your veterinarian out to diagnose mEA. This disease causes reduced athletic performance, and there are different subtypes of mEA that benefit from specific medical therapies. In some cases, mEA progresses to sEA.

Equine Asthma and  Air Quality
What does equine asthma have to do with air quality? A lot, it turns out. Poor air quality, or air pollution, includes the barn dusts—the allergens and moulds in hay and the ground-up bacteria in manure, as well as arena dusts and ammonia from urine. Also, very importantly for both people and horses, air pollution can be from gas and diesel-powered equipment. This includes equipment being driven through the barn, the truck left idling by a stall window, or the smog from even a small city that drifts nearly invisibly over the surrounding farmland. Recently, forest-fire smoke has been another serious contributor to air pollution. 

Smog causes the lung inflammation associated with mEA. Therefore, it is also likely that air pollution from engines and forest fires will also trigger asthma attacks in horses with sEA. Smog and smoke contain many harmful particulates and gases, but very importantly they also contain fine particulate matter known as PM2.5. The 2.5 refers to the diameter of the particle being 2.5 microns. That’s roughly 30 times smaller than the diameter of a human hair. Because it is so small, this fine particulate is inhaled deeply into the lungs where it crosses over into the bloodstream. So, not only does PM2.5 cause lung disease, but it also causes inflammation elsewhere in the body including the heart. Worldwide, even short-term exposure is associated with an increased risk of premature death from heart disease, stroke, and lung cancer. This PM2.5 stuff is not trivial!

In horses, we know that PM2.5 causes mEA, so it’s logical that smog and forest-fire smoke exposure could exacerbate asthma in horses, but we don’t know about heart disease or risk of premature death.

Symptoms, Diagnostic Tests and Treatments

Equine asthma manifests with a spectrum of symptoms that vary in severity and the degree of debilitation they cause. Just like in people with asthma, the airways of horses with mEA and sEA are “hyperreactive.” This means that the asthmatic horse’s airways are extra sensitive to barn dusts that another horse’s lungs would just “ignore.” The asthmatic horse’s airways constrict, or become narrower, in response to these dusts. This narrowing makes it harder to get air in and out of the lungs. Think about drinking through a straw. You can drink faster with a wider straw than a skinnier one. It’s the same with air and the airways. In horses with mEA, the narrowing is mild. In horses with sEA, the constriction is extreme and is the reason why they develop the “heaves line”; they have to use their abdominal muscles to help squeeze their lungs to force the air back out of their narrow airways. They also develop flaring of their nostrils at rest to make their upper airway wider to get more air in. Horses with mEA do not develop a heaves line, but the airway narrowing and inflammation do cause reduced athletic ability.

The major signs of mEA are coughing during or just after exercise that has been going on for at least a month and decreased athletic performance. In some cases, there may also be white or watery nasal discharge particularly after exercise. Often, the signs of mEA are subtle and require a very astute owner, trainer, groom, or rider to recognise them.

Another very obvious feature of horses with sEA is their persistent hacking cough, which worsens in dusty conditions. “Hello dusty hay, arena, and track!” The cough develops because of airway hyperreactivity and because of inflammation and excess mucus in the airways. Mucus is the normal response of the lung to the presence of inhaled tiny particles or other irritants. Mucus traps these noxious substances so they can be coughed out, which protects the lung. But if an asthma-prone horse is constantly exposed to a dusty environment, it leads to chronic inflammation and mucus accumulation, and the development or worsening of asthma along with that characteristic cough.

Accurately Diagnosing Equine Asthma

Veterinarians use a combination of the information you tell them, their observation of the horse and the barn, and a careful physical and respiratory examination that often involves “rebreathing.” This is a technique where a bag is briefly placed over the horse’s nose, causing them to breathe more frequently and more deeply to make their lungs sound louder. This helps your veterinarian hear subtle changes in air movement through the lungs and amplifies the wheezes and crackles that characterise a horse experiencing a severe asthma attack. Wheezes indicate air “whistling” through constricted airways, and crackles mean airway fluid buildup. The fluid accumulation is caused by airway inflammation and contributes to the challenge of getting air into the lung. 

Other tests your veterinarian might use are endoscopy, bronchoalveolar lavage, and in the specialist setting, pulmonary function testing. They will also perform a complete blood count and biochemical profile assay to help rule out the presence of an infectious disease. 

Endoscopy allows your veterinarian to see the mucus in the trachea and large airways of the lung. It also lets them see whether there are physical changes to the shape of the airways, which can be seen in horses with sEA. 

Bronchoalveolar lavage, or “lung wash” is how your veterinarian assesses whether there is an accumulation of mucus and inflammatory cells in the smallest airways that are too deep in the lung to be seen using the endoscope. Examining lung wash fluid is a very important way to differentiate between the different types of mEA, between sEA in remission and an active asthma attack, and conditions like pneumonia or a viral lung infection. 

Finally, if your veterinarian is from a specialty practice or a veterinary teaching hospital, they might also perform pulmonary function testing. This allows your veterinarian to determine if your horse’s lungs have hyperreactive airways (the hallmark of asthma), lung stiffening, and a reduced ability to breathe properly. 

Results from these tests are crucial to understanding the severity and prognosis of the condition. As noted earlier, mEA can go away on its own; but medical intervention may speed healing and the return to athletic performance. With sEA, remission from an asthmatic flare is the best we can achieve.  As the disease gets worse over time, eventually the affected horse may need to be euthanised.

Management, Treatment and Most Importantly—Prevention
Successful treatment of mEA and sEA flares, as well as long-term management, requires a multi-pronged approach and strict adherence to your veterinarian’s recommendations.

Rest is important because forcing your horse to exercise when they are in an asthma attack further damages the lung and impedes healing.  To help avoid lung damage when smog or forest-fire smoke is high, a very useful tool is your local, online, air quality index (just search on the name of your closest city or town and “AQI”).  Available worldwide, the AQI gives advice on how much activity is appropriate for people with lung and heart conditions, which are easily applied to your horse. For example, if your horse has sEA and if the AQI guidelines say that asthmatic people should limit their activity, then do the same for your horse. If the AQI says that the air quality is bad enough that even healthy people should avoid physical activity, then do the same for you AND your horse. During times of poor air quality, it is recommended to monitor the AQI forecast and plan to bring horses into the barn when the AQI is high and to turn them out once the AQI has improved.

Prevent dusty air. Think of running your finger along your tack box – whatever comes away on your finger is what your horse is breathing in. Reducing dust is critical to preventing the development of mEA and sEA, and for managing the horse in an asthmatic flare. 

Logical daily practices to help reduce dust exposure:

• Turn out all horses before stall cleaning

• Wet down the aisle prior to sweeping

• Never sweep debris into your horse’s stall

• Use low-dust bedding like wood shavings or dust-extracted straw products, which should also be dampened down with water

• Reduce arena, paddock, and track dust with watering and maintenance

• Consider low-dust materials when selecting a footing substrate

• Steam (per the machine’s instructions) or soaking hay (15–30 minutes and then draining, but never store steamed or soaked hay!) 

• Feed hay from the ground

• Feed other low-dust feeds

• Avoid hay feeding systems that allow the horse to put their nose into the middle of dry hay—this creates a “nosebag” of dust

Other critical factors include ensuring that the temperature, humidity and ventilation of your barn are seasonally optimised. Horses prefer a temperature between 10–24 ºC (50–75 ºF), ideal barn humidity is between 60–70%. Optimal air exchange in summer is 142 L/s (300 cubic feet/minute). For those regions that experience winter, air exchange of 12–19 L/s (25–40 cubic feet/minute) is ideal. In winter, needing to strip down to a single layer to do chores implies that your barn is not adequately ventilated for your horse’s optimal health. Comfortable for people is often too hot and too musty for your horse! 

Medical interventions for controlling asthma are numerous. If your veterinarian chooses to perform a lung wash, they will tailor the drug therapy of your asthmatic horse to the results of the wash fluid examination. Most veterinarians will prescribe bronchodilators to alleviate airway constriction. They will also recommend aerosolised, nebulised or systemic drugs (usually a corticosteroid, an immunomodulatory drug like interferon-α, or a mast cell stabilisers like cromolyn sodium) to manage the underlying inflammation. They may also suggest nebulising with sterile saline to help loosen airway mucus and may suggest feed additives like omega 3 fatty acids, which may have beneficial effects on airway inflammation. 

New Research and Future Directions

Ongoing research is paramount to expanding our knowledge of what causes equine asthma and exploring innovative medical solutions. Scientists are actively investigating the effects of smog and barn dusts on the lungs of horses. They are also working to identify new targeted therapies, immunotherapies and other treatment modalities to improve outcomes for affected horses.

Conclusion

Both mild and severe equine asthma are caused and triggered by the same air pollutants, highlighting the need for careful barn management. The alarming rise in air pollution levels poses an additional threat to equine respiratory health. Recognising everyday coughs as potential warning signs and implementing proper diagnostic tests, day-to-day management practices and medical therapies are crucial in combating equine asthma. By prioritising the protection of our horse’s respiratory health and staying informed about the latest research, we can ensure the well-being of our equine companions for years to come.

Gastric ulcers in racehorses – what trainers should know

Article by Dr Michael Hewetson

Why are gastric ulcers so important in racehorses?

Gastric ulcers are very prevalent in racehorses, with between 52% and 93% of horses in active training affected. This is significant, because gastric ulcers can impact both the horse's performance and its overall health and welfare, which in turn can have financial and competitive implications for their owners, trainers, and the racing industry as a whole. 

Gastric ulcers can affect a horse's performance by causing abdominal discomfort and reduced appetite. This can lead to changes in stride length and decreased energy levels that may impact their racing performance. Horses with gastric ulcers may also exhibit changes in behaviour, such as nervousness, aggression, or reluctance to train or race, which again, can affect their overall performance and temperament. If left untreated, gastric ulcers can lead to more serious health concerns such as colic, potentially requiring costly medical intervention and downtime for the horse. But most importantly, gastric ulcers are a welfare issue for the Thoroughbred racing industry, and with growing public scrutiny on the industry, ensuring the well-being of racehorses is a priority, and addressing gastric ulcers promptly should be considered part of responsible horse management. This requires a close working relationship with your vet, who will be able to give you expert advice about diagnosis, treatment, and management of this frustrating disease. 

Understanding gastric ulcers

FIGURE 1

Equine gastric ulcer syndrome (EGUS) is a general term used to describe erosions and ulcers of the horse’s stomach and is similar to the term peptic ulcer disease in people. Unlike people however, the horse is unique in that the stomach lining (mucosa) is divided into an upper squamous and a lower glandular portion (figure 1); and it is important to realise that there are differences between these two regions with respect to how these lesions develop, their prevalence, associated risk factors and response to treatment. Therefore, when referring to EGUS, your vet may use the terms Equine Squamous Gastric Disease (ESGD) and Equine Glandular Gastric Disease (EGGD) to clearly distinguish the anatomical region of the stomach affected. 

FIGURE 2

There does not appear to be a clear relationship between the presence of squamous disease and glandular disease, and the fact that both conditions may occur concurrently in the same horse does not indicate that they are associated. In the case of squamous disease, the cause of the ulcers is well understood, with a variety of managemental risk factors (e.g. increase in exercise intensity, low roughage/high starch diet, stall confinement) contributing to an increase in the exposure of the squamous mucosa to acid. The squamous mucosa is not normally exposed to acid. As such it is inherently susceptible to acid injury, and with prolonged acid exposure, ulcers may develop (figure 2).

FIGURE 3

In contrast to squamous disease, the cause of glandular disease is poorly understood. The glandular mucosa is fundamentally different from the squamous mucosa in that it is exposed to a highly acidic environment under normal physiological conditions. As such, it is only when there is a breakdown of the normal defence mechanisms that protect the glandular mucosa from acidic gastric contents that glandular disease occurs. While ulcers are most commonly seen with squamous disease, horses with glandular disease rarely present with ulcers. Rather, the lesions are more consistent with an erosive inflammatory gastritis and can vary widely in their appearance (figure 3). There is a now evidence to suggest that stress, both psychological (e.g. multiple riders or caretakers; confinement; stress associated with transport and competition) and physiological (e.g. increases in the total amount and frequency of exercise without adequate rest periods) may increase the risk of glandular disease in horses. This may be due to a variety of mechanisms including a reduction in the mucus coating and blood supply to the glandular mucosa; both of which compromise the gastric barrier, resulting in acid injury.

The prevalence of gastric ulcers appears to vary with age, use, stage of training, as well as the region of the stomach affected. The prevalence of squamous disease is consistently highest in performance horses, with 52-93% of Thoroughbred racehorses found to be affected. The prevalence of glandular disease is less well reported, however up to 47% of Thoroughbred racehorses may be affected. 

Why are racehorses so susceptible to gastric ulcers?

It is most likely because of their unique management when compared to most other horse populations; and the intensity of exercise that is inherent of racing competition. For example, it has been shown that the risk of squamous disease increases with an increase in the intensity of exercise and the duration of time at work. Strenuous exercise causes an increase in intra abdominal pressure associated with contraction of the abdominal muscles1. This results in compression of the stomach, and exposure of the sensitive squamous mucosa to acidic gastric content (acid splash). Strenuous exercise has also been shown to cause an increase in a hormone called gastrin, which stimulates acid production in the stomach. 

Several factors associated with management have also been shown to increase the risk of squamous disease, many of which are imposed on racehorses at the commencement of training or during racing competition. These include a high starch/low roughage diet, intermittent fasting, stall confinement, transport, intermittent access to water and administration of hypertonic solutions of electrolytes. In fact, exposure to a combination of a high starch diet, stall confinement and strenuous exercise has been shown to induce ulcers in as little as 7 days; and intermittent fasting is so effective at inducing ulcers that it is used as a model for squamous disease in experimental studies. Thoroughbred racehorses are also exposed to many of the risk factors for glandular disease, most notably, multiple riders or caretakers; confinement; and stress associated with transport and competition.

How do you know if your horse has gastric ulcers and how might they affect performance?

A variety of clinical signs may suggest that a horse has gastric ulcers, however there is currently very little evidence to support a direct association between any of these signs and the presence or absence of ulcers seen on gastroscopy. This is likely because most of the clinical signs are non-specific and are often very subjective. This is complicated further by the fact that horses with gastric ulcers may not demonstrate clinical signs and if they do, the signs do not necessarily correlate with the severity of the lesions seen on gastroscopy. Clinical signs suggestive of gastric ulcers should therefore always be interpreted with caution, and most importantly, gastroscopy should always be performed to confirm the disease (figure 4).

In racehorses, gastric ulcers have been associated with poor appetite, poor body condition, changes in behaviour (including an aggressive or nervous attitude), post prandial colic, stereotypic behaviour and resentment of girthing. Any one of these clinical signs can potentially have an indirect effect on performance (for example, through reduced appetite or interruption in training), but the big question is if gastric ulcers themselves, in the absence of other clinical signs, have an effect on performance. Despite the fact that it is a well entrenched ’fact’ amongst trainers that gastric ulcers have a direct effect on poor performance or reluctance to train, there is surprisingly little evidence in the literature to back this up. This may be in part due to the difficulties in excluding the many confounding factors that might influence poor performance (e.g. lameness, respiratory disease etc.). 

The mechanism by which gastric ulcers may affect performance has not been identified but is likely to be related to epigastric pain. In people, epigastric pain is defined as pain localised to an area below the sternum and above the umbilicus and is common in athletes with gastro-oesophageal reflux disease (GERD). Acid reflux onto the sensitive squamous mucosa of the oesophagus during exercise causes a “burning sensation” that gets worse with increasing exercise intensity and has been shown to affect performance. Horses with squamous gastric disease have similar lesions to those causing GERD in human athletes, and the problem is likely to be exacerbated by the fact that the squamous mucosa extends from the oesophagus into the upper one-third of the stomach and is not protected by an oesophageal sphincter. Interestingly, a recent study in human athletes suggested that GERD may be associated with increased abdominal pressure during exercise, a mechanism that I have already alluded to in the equine athlete. How exactly epigastric pain impacts on athletic performance in the horse is a matter of ongoing speculation. One theory is that it may affect stride length. It has been shown that horses with gastric ulcers have a reduced stride length when galloping, likely due to abdominal discomfort. Stride length and lung ventilation are mechanically coupled in the galloping horse, and therefore, reduced stride length will result in decreased oxygen uptake, thus limiting aerobic capacity during peak exercise.

How are gastric ulcers treated and what can you do to prevent them?

Let’s turn our attention now to the treatment of gastric ulcers. Because there is currently little evidence to suggest an association between clinical signs and the presence or severity of gastric ulcers, treatment should always be based on gastroscopic evidence of ulcers. Some trainers may still choose to commence treatment based entirely on clinic signs without gastroscopy and assess for a clinical response. I would caution against this approach, as it can be costly if the horse does not have ulcers, and gastroscopy is still going to be necessary to conclusively rule out gastric ulcers if clinical improvement is not seen with treatment.

Treatment of gastric ulcers will vary depending upon the severity and the location of the ulcers and your vet will be able to give you advice on the best approach. In most cases treatment consists of management and dietary modification in conjunction with the use of proton pump inhibitors which suppress acid production. Oral omeprazole is the drug of choice and is currently the only licensed drug for the treatment and prevention of gastric ulcers in horses in the UK and Ireland.   

Administering oral omeprazole on an empty stomach can improve the bioavailability of the drug. This can be achieved practically by administering it first thing in the morning at least 1 hour prior to feeding. This ensures the stomach will be empty as horses eat very little during the night even if they have access to forage. 

The duration of treatment will depend on the location of the lesions, with squamous disease tending to heal faster than glandular disease. In most cases, your vet will prescribe oral omeprazole for 3-4 weeks and then the requirement for additional medication will be determined following a repeat gastroscopy. In the case of glandular disease, oral omeprazole is often combined with sucralfate, which adheres to the damaged mucosa, providing a physical barrier while also stimulating mucus secretion, both of which reduce potential exposure to acid. Omeprazole is a controlled drug, and therefore needs to be withdrawn prior to competition. The BHA published detection time for oral omeprazole is ≤ 48hrs, so withdrawal of the drug 3-5 days before competition would be prudent. There is, however, some concern that the requirement for withdrawal times might influence the efficacy of oral omeprazole treatment in racehorses. Many vets report reoccurrence of squamous disease following discontinuation of treatment with omeprazole, often within as little as 3 days, and this was demonstrated in a recent study comparing withholding periods for oral omeprazole treatments in racing Thoroughbreds6. The authors reported a squamous disease prevalence of 83% in horses after a “2 clear days'' recommended withholding period for oral omeprazole, which was an increase from 25% of horses with squamous disease before the recommended withholding period, and they theorised that ‘rebound acid secretion’ may be implicated. This phenomenon occurs following the discontinuation of proton pump inhibitor drugs such as oral omeprazole, and is linked to a loss of negative feedback from gastric acid during treatment that causes an increased secretion of the hormone gastrin that can persist for up to 2-4 days after the last dose of omeprazole has been administered. This results in a short period of increased gastric acid production when treatment is stopped. Whilst nothing can currently be done about the required withdrawal periods during racing, strict management practices should be implemented for the 2-4 days following cessation of omeprazole treatment to mitigate against development of squamous gastric disease. This could include ensuring provision of adequate roughage during this time, avoiding fasting or withholding water, and perhaps limiting exercise or transport if possible.

Additional management and dietary adaptations which may help prevent gastric ulcers and can be implemented longer term in a racing yard include free choice access to roughage (and if not, ensuring that roughage is provided at intervals of no more than 4-6 hours); turn out into a paddock with good quality grazing where possible; a low starch/high fat diet (or alternatively, smaller concentrate meals more frequently); reduction/avoidance of any potential stressors; and provision of regular rest days. Where possible, training schedules should be adjusted so that they occur later in the day when enough roughage has been consumed to ensure that there is a mat of roughage in the stomach to buffer acid in the upper squamous portion and to reduce acid splash during exercise. Alternatively, a handful of palatable chaff should be fed 20 minutes prior to exercise. 

Numerous supplements are marketed for prevention of gastric ulcers, however there is currently very limited evidence to support their use.

The Gerald Leigh Memorial Lectures 2023

The Gerald Leigh Memorial Lectures, is an annual  gathering devoted to the racing industry and the health and wellbeing of the horses involved.  

This year, equine veterinarians, researchers, students and industry professionals from around the world attended the event, held June 8, 2023, at the historic Tattersalls Sales in Newmarket, England.  

There were insightful and informative lectures that educated the attendants but also instigated a healthy, lively debate on the health and welfare of the training and competing of horses. The underlying theme that was present during the whole event was all members of the conference had a deep passion and commitment to continuously progress and improve on managing the welfare and wellbeing of the horses in the industry, both on and off of the track.  

Two very special guest speakers, Sir Mark Prescott and Luca Cumani, wonderfully illustrated these sentiments as they described their reflections on the improvement and enhancement of horse safety.  

Horse racing may be regarded as an elite sport, and all activities involving horses have an element of risk. All stakeholders in the racing industry must continuously work to ensure that the risks are minimised in order to reduce the number of injuries and fatalities that may occur in training and on the racecourse.  There are now well-publicised concerns regarding the acceptability of exposing horses to risk in racing.  These lectures and all of the attendees embraced the values of the public will so that there can be continued acceptance of horse sports.   

Reducing the incidence of fractures in racing 

Christopher Riggs of The Hong Kong Jockey Club clearly outlined the various strategies to reduce the risk of fractures in racehorses. There are two principal strategies that may used to reduce the incidence of severe fractures in horses while racing and training:

1. Identifying extrinsic factors that increase risk and take action to minimise them. 

An example would be investigating different racing surfaces in order to determine which may provide the safest racing surface. However, studies have provided limited evidence and support for subtle extrinsic factors.

2. Identifying individuals that are at increased risk and prevent them from racing or minimise that risk until the risk has subsided.  

There are many research routes that are being undertaken to identify those horses that may be at a higher risk of fractures. There are investigations involving heritability and molecular studies that may provide evidence of genetic predisposition to fracture. However, Dr. Riggs explained that further understanding of the relationship between genetic, epigenetic and environmental factors is required before genetic screening is likely to be of practical use.  

Pre-race screening of horses by diligent clinical examination is poor at reducing the incidence of fracture. Dr. Riggs described another strategy that may assist with a clinical examination that is the use of biomarkers in blood and urine.  

Unfortunately, the precision to be of practical value has so far remained relatively unrewarding.  Wearable technology that records biometric parameters, including stride characteristics, has shown some promise in identifying horses that are at increased risk of fracture; although Dr. Riggs explained that this work requires further development.  

Finally, Dr. Riggs described both the use and current limitations of  diagnostic imaging in identifying pre-fracture pathology in order to identify a horse at imminent risk of fracture.  He conceded that further knowledge of the significance of the range of abnormalities that can be detected by imaging is incomplete.

Dr. Riggs concluded his lecture by expressing that the implementation of  diagnostic imaging to screen  “high-risk” horses identified through genetic, epidemiology, biomarkers and/or biometrics may be the best hope to reduce the incidence of racing fractures. This field can be advanced with further studies, especially of a longitudinal nature.

Professor Tim Parkin of Bristol Veterinary School discussed the need for further investment in welfare research and education. One avenue of investment that should be seriously considered is the analysis of data related to (fatal) injuries in Thoroughbred racing over the last 25 years.  

It was expressed, with the abundance of data that has been collected, that some risk factors would be relatively simple to identify. An encouraging example in the collection and use of data to develop models in predicting and potentially preventing injury has been conducted by the Hong Kong Jockey Club funded by the Hong Kong Jockey Club Equine Welfare Research Foundation. This may provide an opportunity to pilot the use of risk profiling to contribute to decision-making about race entries.  In addition, the results of the pilot study combined with other sources of data may encourage race authorities to mandate the collection of veterinary and training data in order to help in risk mitigation.

Horse racing is an international sport, and there are different governing bodies that ensure racing integrity. However, the concept of social licence equestrian sports and Thoroughbred horse racing continues to gain significant public attention.  Therefore, racing governing bodies are increasingly aiming to provide societal assurances on equine welfare. 

Dr. Ramzan of Rossdales Veterinary Surgeons provided an eloquent and clear message during his lecture that race yard veterinarians and trainers are instrumental in ensuring good horse health and welfare and reducing serious injury of the horse both while training or racing, which will provide sufficient trust and legitimacy from the public and society.  This feasible goal can be reached with good awareness of members involved in the care and training of each individual horse and conveying this information and any concerns to their veterinarian.  The veterinarian can also contribute by honing their knowledge and skills and working closely with yard staff in order to make appropriate and better targeted veterinary intervention.   

In the last two decades, there has been an incredible evolution and exciting developments in diagnostic imaging in the veterinary profession. It is believed that these technologies can provide a significant contribution to helping in mitigating fracture risks to racehorses on the course and in training.  

Professor Mathieu Spriet of University of California, Davis, described how these improvements in diagnostic imaging has led to the detection of early lesions as well as allowing the monitoring of the lesions’ evolution.  

He continued by explaining the strengths and limitations of different imaging modalities such as computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET).  Being one of the leaders in the use of PET in equine veterinary medicine, he presented further insight on how this particular modality provides high-resolution 3-D bone scans while being very sensitive to the identification of bone turn-over prior to the development of structural changes and allowing one to distinguish between active and inactive processes when structural changes are present.  

He concluded his impressive lecture by providing evidence with amazing PET images that the role of imaging is not merely for diagnostic purposes to characterise clinical abnormalities, but can also be used as a screening tool in certain horse populations for fracture risk assessment or for the monitoring of lesions to provide clearance for racing. 

Fractures, due to bone overloading rather than direct trauma occur commonly in Thoroughbred racehorses and are the leading cause of euthanasia on the racecourse. Despite many changes to race conditions, the number of catastrophic fractures has remained relatively static, with approximately 60 horses a year having a fatal fracture during a race in the UK.  

Against this backdrop, there have been great developments in the diagnosis and treatment of fractures in the last 40 years. Prevention of racecourse and training fractures would be ideal so the development of efficacious techniques to screen horses at risk may reduce the incidence and preserve social licensing.  

One technique discussed by Dr. Ian Wright of Newmarket Equine Referrals was to help mitigate the impact of racecourse fractures, which would be acute immobilisation of racecourse fractures, thus, reducing associated pain and anxiety while optimising clinical outcome and reducing on course fatality rates. Because of our increased understanding of fracture pathogenesis and their associated biomechanics, effective fracture immobilisation has been made possible. The majority of fractures that occur in flat racing and between obstacles in jump racing, are a result of stress or fatigue failure of the bone and not associated with trauma.  

In addition, fractures seen on the racecourse are often found in the same specific sites (i.e., metacarpal/metatarsal condyles and the proximal sesamoid bones of the fetlock) and have repeatable configurations. With this understanding and knowledge, racecourse veterinarians can optimally immobilise a fracture in a logical and pre-planned manner.  

As Dr. Wright expressed, this allows the fracture patient to have reduced pain and anxiety and enable the horse to be moved from the course comfortably so that it can be further examined. Ultimately, this allows the veterinarian and all stakeholders to make effective and judicious decisions for the sake of the horse’s welfare and wellbeing. As Dr. Wright concluded, this benefits both horses and racing.

Dr. Debbie Guest of the Royal Veterinary College discussed a different approach in mitigating the risk of fractures during training and racing by developing novel tools to reduce catastrophic fractures Thoroughbreds. Because it has been found that some horses are more inherently predisposed to fractures than other horses, Dr. Guest and her team have developed a genome-wide polygenic risk score so that one can potentially calculate an individual horse’s risk of fracturing during training or racing compared to the population as a whole.  

This strategy may contribute in identifying genetically high-risk horses so that additional monitoring of the patients can be exercised during their careers and also leading to fracture risk, which are found to be the cause of approximately half of these incidents.  

The system of using DNA testing to identify biological processes that may or may not be present ultimately leading to fracture risk may be a powerful tool in lowering the risk of catastrophic fracture and requires further research and application.

Cardiac events & sudden cardiac death in training and racing

In racehorses, sudden death that is associated with exercise on the racetrack or during training is a serious risk to jockeys and adversely affects horse welfare and the public perception of the sport. It is believed 75% of race day fatalities result from euthanasia following a catastrophic injury. The other 25% of fatalities is due to sudden deaths and cardiac arrhythmias are found to be the cause of approximately half of these incidents. The lectures focused on this area of concern by providing three interesting lectures on cardiac issues in the racehorse industry.  

Dr. Laura Nath of the University of Adelaide, explained the difficulties in identifying horses that are at risk of sudden cardiac death. It is believed that part of the solution to this difficult issue is the further development and use of wearable devices including ECG and heart rate monitors.  

With the use of these technologies, the goal would be to recognise those horses that are not progressing appropriately through their training and screen these horses for further evaluation. This course of action has been seen in human athletes that develop irregular rhythms that are known to cause sudden cardiac death with the use of computational ECG analysis, even when the ECGs appear normal on initial visual inspection.  

Knowing that ECGs and particularly P-waves are used as a non-invasive electrocardiographic marker for atrial remodelling in humans, Dr. Nath recently completed a study on the analysis variations in the P-wave seen on ECGs in athletic horses and found that increases of P-waves in racehorses are associated with structural and electrical remodelling in the heart and may increase the risk of atrial fibrillation (cardiac event).

Dr. Celia Marr of Rossdales Veterinary Surgeons continued the discussion of cardiac disease in both the training and racing of horses. Unfortunately, cardiac disease knowledge does lag compared to musculoskeletal and respiratory diseases when considering the causes of poor performance in racehorses. Due to the fact that cardiac rhythm disturbances are fairly common, occurring in around 5–10% of training sessions in healthy horses in Newmarket and over 50% of horses investigated for poor performance, Dr. Marr expressed the need for further research and investigation in this area.  

In addition, this research needs to determine if there is indeed a link between heart rhythm disturbances and repeated episodes of poor performance and sudden cardiac arrest. ECGs and associated technologies are helpful, but there are limitations such as the fact that rhythm disturbances do not always occur every time the horse is exercised.  Therefore, it would be of great value that a robust criterion is established when evaluating ECGs in racehorses. The Horserace Betting Levy Board has provided funding for investigation by initially exploring the natural history of paroxysmal atrial fibrillation (self-correcting form) to understand risk factors and predict outcomes for affected horses.

Continuing the theme of the lectures on irregular heart rhythms and associated sudden cardiac death (SCD) in training and racing, Professor Kamalan Jeevaratnam described his exciting research in using artificial intelligence (AI) to identify horses at increased risk of developing irregular rhythms that may cause SCD.  

AI is an exciting and rapidly expanding field of computer science that is beginning to be implemented in veterinary medicine. With funding by the Horserace Betting Levy Board and the Grayson Jockey Club Research Foundation, Professor Jeevaratnam of the University of Surrey, has piloted three novel algorithms that help predict horses with rhythm abnormalities through the analysis of horses’ ECGs.  

It was acknowledged that further research is required to develop this technology by using data collected from multiple sources, but the initial results are promising in the development of an useful AI tool to identify horses at risk of SCD and prevent catastrophic events, thus, ensuring the welfare of the horse in racing.

Conclusion

The Gerald Leigh Memorial Lectures was a thoroughly successful and enjoyable event attended by a variety of different members of the horse racing industry. Not only did the lecturers provide interesting and valuable information but also excitement for the future of racing.  It was very clear that all the lecturers and attendees were passionate and committed to the racehorse welfare and wellbeing as well as retaining the social licence for an exciting sport. 

Shared ownership

It has always struck me—as someone with a keen interest in most sports—that the lack of harmonisation around various rules and issues such as interference, jockey’s weights, and doping isn’t helpful as racing remains such a puzzle to most of the world.

This is evident too in the area of shared ownership, of syndicates, racing clubs and the developing area of micro share groups.

Never has it been more important for racing to attract fresh blood, with its core support ageing and the sport barely causing a ripple in mainstream media. Shared ownership is a foolproof mechanism for unearthing new acolytes because emotion and feeling will trump catchy slogans or slick promotional videos every time. If you want converts, having them in the parade ring as part of the inner circle and seeing their horse run and contend or win is your best bet.

Piers Winkworth, racing manager of Kennet Valley Thoroughbreds, summed it up well after Dragon Leader maintained his 100 per cent record from three runs by landing the £147,540 first prize in the Goffs UK Harry Beeby Premier Yearling Stakes at York’s prestigious Ebor meeting in August.

Dragon Leader with Ryan Moore up wins the 2023 Premier Yearling Stakes at York’s prestigious Ebor meeting in August.

“This is what syndicates are all about really—having cracks at these ultra-valuable sales handicaps with modestly bought horses,” Winkworth noted. “Dragon Leader, a £45,000 Donny yearling, goes and wins the big race by some distance under Ryan Moore. It was thrilling for all of our owners. We had about 16 people up at York to see him, and there were great celebrations after the race”.

Johnny Murtagh has participated in many such celebrations, having had a hefty number of syndicates at Fox Covert Stables since he took out a licence to train at the conclusion of a stellar riding career.

The Curragh-based conditioner secured his first Gp. 1 triumph with Fitzwilliam Racing’s Champers Elysees in 2020, and bagged his first Classic the following season when Sonnyboyliston swooped to score in the Comer Group International Irish St Leger for Kildare Racing Club.

This season, Murtagh has had runners for 11 syndicates, saddling winners for six of them. So enamoured is he with shared ownership that he has just launched a new racing club, Racing Revolution, more of which anon.

“There’s nothing better than coming back into the ring and seeing people who never thought they’d ever own a horse so happy”, reports Murtagh.

“We’ve been very lucky with Fitzwilliam. They ended up winning a G.p 1. We now have the likes of the Brunabonne Syndicate—lads from where I grew up. They’ve been so lucky with Mashhoor. He won a couple of big races (including at Gp. 3 level), brought the lads to York and Ascot, and ran on all the big days”.

The idea of the racing club came out of Mashhoor’s Listed triumph on Tattersalls Irish 2000 Guineas day at Curragh Racecourse in May. In particular, it was the reaction of Tommy Dowd, a celebrated former Gaelic footballer who led Meath to All-Ireland glory in 1996, that resonated.

“Tommy Dowd picked up the Sam Maguire as captain of Meath and he said, ‘This is the same feeling as that.’”

Dr Paull Khan, secretary-general of the European and Mediterranean Horseracing Federation summarises the overall situation brilliantly.

“In many countries (in and outside our region), racing is struggling to maintain its popularity and relevance, as societal practices and preferences shift,” notes Khan.

“Broadening the base of racehorse ownership may well prove a key weapon in countering this trend. Quite simply, the more people that have an involvement in owning a racehorse, the more our sport becomes embedded in society.

“For racing authorities, the challenge is not limited to promotion. Appropriate Rules of Racing must underpin such activity, which allow for and define co-ownership options.

“But there is also a potential downside, in that the creation of ownership entities which encompass large groups of individuals brings with it increased risks of incompetent or, yet worse, fraudulent management. Any examples of people suffering bad experiences, which are not satisfactorily dealt with, are likely to gain much publicity and have the effect of putting off future owners. So the final aspect to which racing authorities must give thought is the need for effective regulatory oversight, to minimise this risk”.

What follows is something of a potted overview of the situation in Europe, thanks to a number of different stakeholders from governing bodies to trainers and plenty more in between. 

BRITAIN

Establishing a new syndicate isn’t laborious in Britain, and only the manager/syndicator must register as an owner. The members do not have to register, but an updated list of members must be provided to the BHA as well as the percentage share held by each one.

Racing clubs are focussed entirely on the experience of ownership but without having any equity in the horse or share in whatever proceeds it accrues while racing. Members pay an annual fee to enjoy most of the other benefits of ownership, on race day and while in training. Once again, only the person setting up or running the club must register.

Micro share groups are becoming more visible and are a very cheap way to become involved in racing as a tiny percentage of a share, normally a fraction of 1 percent , can be acquired for as little as £40. Like racing clubs, they are primarily experiential, though members are owners and are entitled to the equivalent cut of any money accumulated.

All forms of shared ownership in Britain are subject to a code of conduct that includes specific mandatory clauses in each written contract. Transparency and protection are the key tenets of the code. The BHA has committed to auditing a proportion of syndicate/racing club/micro share contracts to ensure compliance.

George Baker’s ‘Have horse, will travel,’ mantra has always made him attractive to shared ownership groups. The Robins Farm trainer has saddled winners all over the world and is as good a host as he is a trainer.

The Surrey-based conditioner has his own racing club, the George Baker Racing Club, which provides all the perks of an involvement in racehorses, including open house visits, parade ring passes, regular communication, picnics at Royal Ascot and Glorious Goodwood, and even a share in a prize money. 

Baker joins Andrew Balding and Harry Eustace as trainers for the MyRacehorse fractional share group, making a big splash on this side of the Atlantic and having initially enjoyed stupendous success when established in America by Michael Behrens.

The relationship with MyRacehorse began with Get It and Watchya racing in Bahrain; and the ambition was rewarded by the former being awarded a victory after the winner on the day was disqualified due to a positive sample.

“The key point here is making racehorse ownership accessible to absolutely everybody in the way that it has been for a few years now and obviously in Australia, where the big syndicates have had massive success”, Baker declares. 

“Like our horse (Get It) at Wolverhampton (on September 7) that won the Racing League race—a share in him was £45. The wonderful thing about a share at whatever level [is] the horse becomes your horse, regardless of whether you’ve paid a million pounds or forty pounds. 

“We all know it’s the way forward because we’ve just got to get as many people as we can into this game, and of course you hope that some of them become more heavily involved in the sport and that it evolves to a longer association; but the most important thing is showing racing as a viable means of enjoyment”.

A degree of suspicion has lingered around micro share operations, but Baker is happy to go to bat for MyRacehorse. 

“I can’t speak for any of the other micro share entities, though obviously I’ve heard rumours of numbers not quite stacking up or that horses worth ‘x’ have been marketed for ‘x + y + z’; but that’s not something I can be quoted on because I haven’t had intimate involvement or knowledge.

“I know from the MyRacehorse perspective, they are wholly transparent and very keen to be treated as you would treat a security in the stock market. They want to create a secondary market so people can trade in and out of their shares. 

“People demand absolute transparency and absolute integrity and from my experience, clearly that’s what MyRacehorse have based their brilliant business on in America and Australia; and they’re trying to bring the same criteria here. And that’s absolutely correct. I don’t want to be involved with any organisation or micro share entity where there’s a level of suspicion around the numbers. And that’s why MyRacehorse is creating a niche and an attractive market”.

Baker returns to Get It and Wolverhampton to ram home his point about the impact feeling a winner can have regardless of financial outlay.

“There was one of the guys in the winner’s enclosure who’d won a share that night in a race card competition that MyRacehorse had organised with the Racing League. And there he is in the winner’s enclosure being photographed with (jockey) Paul Mulrennan and the horse. The guy was almost in a state of shock, but he was absolutely loving it”.

IRELAND

Ireland is among the most proactive European jurisdictions for the promotion and growth of multiple ownership. Figures from 2022 indicate that the number of syndicates increased by 24 per cent to 825, comprising 8,030 people. 

The number of racing clubs increased by 6 per cent, comprising 1,683 members. 

People can join existing syndicates or racing clubs or establish their own. Syndicates in Ireland comprise 3–100 people, while racing clubs can have an unlimited number of members.

The above figure for syndicates also includes the evolving fractional ownership model, with MyRacehorse having horses in training with Joseph O’Brien and Michael O’Callaghan.

“It is a great way to dip your toe in the water and see if it is the pastime for you,” says HRI’s owner development manager, Amber Byrne of shared ownership, who adds that plenty with the means to indulge in sole ownership prefer syndicates as a means of spreading their risk or because they derive more enjoyment from them.

HRI maintains a register of racehorse owners and can void or suspend owner registrations. The onus falls on the agent to ensure the syndicate/club and its members complies with the rules of racing, HRI directives, owner eligibility policy etc. Unlike the BHA, they do not have a specific code of conduct in place but advise that all syndicates and clubs provide them.

Agents must be registered as full owners and provide necessary ID, bank details etc., while a full list of membership including addresses and contact details and shares held must be supplied and continuously updated. Syndicates/clubs must declare if they are selling shares publicly and declare the maximum number of shares available in a particular horse. 

Jack Cantillon, founder of the hugely popular Syndicates.Racing, says HRI has it just right in terms of regulation and oversight.

“We recently registered in France, and it took over a month for our application to be successfully processed; so we should be thankful for how quick it has been for us to do so in Ireland”, Cantillon relates. “We also are registered in New York, and they even wanted my fingerprints before we got over the line! Ireland strikes a balance of enough protections while not over burdening with ridiculous red tape.

“Syndicates are the backbone of building the pipeline of ownership of racehorses throughout the world”, he continues. “We’ve had incidents of people taking a €200 share as their first share in a racehorse and progressing to owning horses worth €100,000 on their own. It’s an amazing journey to see in full sight and something that’s incredibly rewarding”.

Syndicates.Racing has enjoyed spectacular success in a short period in both codes, with runners and winners at a host of major meetings and venues, including graded-winning mares Cabaret Queen and Grangee. Their trainers include Willie Mullins, Joseph O’Brien, Henry de Bromhead, Jessica Harrington, Gavin Cromwell, Peter Fahey, John McConnell, Jack Davison and the aforementioned Johnny Murtagh. They also have horses in training in Britain and America.

“We have been blessed with over a thousand owners that have gotten involved in Syndicates.Racing since its inception and bringing so many of them to the winner’s enclosure has been a hugely rewarding thing… If you do have a positive experience, there’s very few more rewarding experiences of intimate involvement that you can get in any sport”.

As mentioned earlier, Murtagh is such a believer in the benefits of shared ownership that he has just launched his own racing club.

“You’d love people to have a good experience of racing. They’re going to be racing, but they’re going to see behind the scenes as well—even things like a horse being shod or going through the stalls; the ins and outs of JP Murtagh on a weekly basis with a horse ready to run. You’ll have a morning on the gallops, a few get-togethers. I think there’s going to be a great take-up and plenty of entertainment.

“There’s a bit more work, but I only speak to the racing manager and they keep everyone else informed. You’re going to have to employ somebody to take videos and keep it updated every day. I want people to see what’s going on and to feel part of it.

“You like to promote the game as best you can and show it in a good light and maybe in a way that people with some bit of interest want to see more and you never know what it leads to. One fella might say, ‘I enjoyed that; can you buy me a horse?’ Rather than jumping into it straight away, they get a good feel.

“I think it’ll work. We’ve a good horse, and we’ve a plan for the horse. We have everything in place, ready to go. I think people will like to be part of it.

While there is “a bit involved” in setting Racing Revolution up, “Murtagh found HRI very helpful. Ireland’s governing body is full square behind shared ownership as a means of growing the sport and industry.

“The promotion of shared ownership is central to our domestic marketing strategy”, Byrne emphasises. “Syndicates and clubs are key in introducing the ownership concept. We see it as an affordable entry stage into ownership and a way for those interested in racing to get closer to the action and behind-the-scenes access.

“For the most part our domestic marketing promotion concentrates on highlighting multiple ownership. There is no other sport that allows the kind of access that ownership offers and allows fans to get fully immersed in a sport that they love”.

Cantillon sees one area of potential improvement.

“I think we as an industry should invest in a comprehensive customer relationship management system for our owners. We should take advantage of affordable technology available to improve owner experience tenfold. Send a special deal to owners on their birthday, invite them back to the anniversary of their winner last year, issue tickets digitally so there’s no mix-ups at the gate. It’s simple stuff but makes a huge difference”.

FRANCE

Syndicates are known as ecurie de groupe in France, which translates directly to racing stables but are generally known as racing clubs. They are not to be confused with the experiential model of racing clubs in Britain and Ireland and which do not exist in France.

Neither are there any micro share companies, though there have been some initial discussions with MyRacehorse.

“It is certainly an interesting model, one which is full of potential in France,” outgoing managing director of France Galop, Olivier Delloye tells us.

There are 44 syndicates in operation in France, and that figure—while low and down on the 72 recorded in 2014—will increase “in the coming months” according to France Galop’s marketing and ownership development manager, Raphaël Naquet. Ecurie Team Spirit, Shamrock Racing, Ecurie Vivaldi, Ecurie Brillantissime, and High Heels Racing Stable are among the flourishing factions; and there are links to several syndicates on the France Galop website.

As Jack Cantillon touched on, the process of registering a syndicate is more arduous in France than elsewhere. Irish native Timmy Love, who is a colleague of Naquet’s in the ownership development wing of France Galop, concedes that point but insists that this is due to the law of the land rather than the racing regulator.

“Setting up a racing club is probably slightly more bureaucratically heavy than what it would be in Ireland or in England, but that’s just the nature of the French system”, Love asserts. “It’s not a reflection on France Galop. It’s just in France (by law); there is quite a rigorous administration system. It’s quite demanding, but it’s to protect the people already within the sport or those trying to come into it.

“It’s by no means rocket science to get set up over here. Once you get all your different documentation together, it’s no more difficult than anywhere else. You just need slightly more documents in the first place”.

The syndicates must be registered as a company, and that means articles of association, declarations of the company, certificates of incorporation are required to establish the company’s eligibility. Once that is done, the usual proof of identification for the agent running the syndicate is required.

Every member of an ecurie de groupe has an owner’s card that entitles them to the exact same benefits as a sole owner. These include being allowed to bring four guests to every meeting at all the France Galop racecourses, with no exclusions. Being able to do that on Prix de l’Arc de Triomphe day is a phenomenally attractive perk as a syndicate member. 

The provincial tracks are not bound by general rule as regards to how many people are allowed to attend per owner card or runner, but according to Love, they are generally very hospitable.

“For example, I know Middleham Park (Racing) had a winner in Cagnes-Sur-Mer over the winter (Brave Emperor), and the racecourse was very good to the members of that syndicate that travelled over. That is just to give one example, but there are lots of country tracks that look after their owners extremely well”.

France Galop is considering being more proactive in going out into the marketplace to sell the benefits of syndicates as an ownership option. 

“We can see more and more shared ownership is more attractive. It makes the sport more accessible, so it’s certainly something we’re considering; and now we have a good base of racing clubs that are well set up and having a bit of success. It’s becoming an easier product to market”,

French trainers are not as enamoured with shared ownership as their British and Irish counterparts, however, as illustrated by Hélène Hatchiguian of the Association des Entraîneurs de Galop, the French trainers’ association.

“We have more and more owner agreements, but mainly for shared ownership, because having a racehorse is a cost. The consequence is that we have less horses in training,” Hatchiguian observes.

“For a trainer, it is easier and better to have one owner per horse, but now we have less of these owners and more shared ownership. It represents more work for the trainer, and more time (to communicate, for invoicing etc.). If trainers do not have time for it, they need to employ someone to do this job.

“When some shared owners do not pay their training fees, we can appeal to France Galop, the horse cannot run, and it is penalising other owners. In the future, it will be necessary to change the rules: if one or more shared owner does not pay, the horse can still run but the money won by the horse is not paid to the owner but to the trainer’s account”.

GERMANY

Christian von der Recke is cut from the same cloth as George Baker. Land and sea borders are no impediment to the multiple-champion jumps trainer travelling and running horses.

He says running a proper syndicate is difficult in Germany and points us in the direction of Lars-Wilhelm Baumgarten. A former sports agent (with Grand Slam winner Angelique Kerber among his clients), now breeder and board member of Deutscher Galopp, Baumgartner founded Liberty Racing with his wife Nadine and realised a lifetime ambition when Fantastic Moon won the Deutsches Derby in Liberty silks.

Members are glorying in the anticipation of a tilt at the Breeders’ Cup and/or the Japan Cup at present – wherever there is good ground - after the Sarah Steinberg-trained son of Sea The Moon recorded a decisive victory in the Qatar Prix Niel. Some hefty offers came in for the German-bred colt after the romp at ParisLongchamp but they have been rejected by shareholders and he will continue to race for Liberty.

“I worked as a sports agent all over the world and was a lot of times in Australia and saw the syndicates there,” Baumgartner explains. “I decided to sell my company and do what I want—horses, poker, real estate, and coaching. I started breeding and was on the board of German Racing, and I saw the problem: less owners, less breeders.

“I started eight years ago with my partnership ownership, only with two or three friends. We had a lot of success together. Then I decided to make my three- or four-people ownership syndicate bigger and started in 2020, to bring all my owner and breeder know-how to bring more people to horses. That was in my mind, but also in my mind was to win bigger, not just to buy handicap horses for people. We wanted to buy stayers with stamina from good German families for the Classic races, the Derby, the Oaks, and the Leger. 

“The idea was that new people can dream and be part of the bigger races. That was the main vision for Liberty Racing. Nadine and I started with 12 shareholders and four horses. The next year, we had 22 shareholders in four horses and then 30 in five horses. This year we will buy 10 to 12 horses with 90 or 100 owners.

“It’s not easy with the German tax situation. We have a lot of law restrictions to bring money together. It’s not like in England and America. They have more share culture, but we did it. We created a good contract, and we have the okay from the government to do it, and so we started”.

Deutscher Galopp is very helpful, Baumgartner tells us, not least than when he brought 50 people to shout on Liberty Racing’s two Derby runners.

There are more racing clubs in Germany than syndicates, but Liberty Racing is a poster child for the latter model with its professionalism and specific departments to cater for acquisitions, financials, social media, and so on.

“German racing was a closed shop. We have to open it. At the moment, we have 1,800 horses in training. That’s not good. We have to find 1,000 new shareholders in horses, and then we find 100, 200 horses more for trainers to train”.

ITALY

Former top trainer and now flourishing bloodstock agent, Valfredo Valiani, is looking forward to attending all the major European sales in the coming weeks and months, but he won’t be buying for Italian syndicates.

“Italian people usually don’t like syndicates, and it’s something that never took off in Italy,” Valiani remarks. “When I used to train, I tried myself with a couple of friends to set up a few syndicates for a few horses. We had results with the horses. We went up to six partners. But Italians are pretty individual. We’re not used to doing syndicates in anything and especially in racehorses. 

“It’s not that easy to register a syndicate over here. You’re going to need all the papers for every single partner in the syndicate. So it’s really tough. And then, just the representative is allowed to get to the parade ring. 

“We need syndicates because Italian racing is not flying, especially in quality; and when you get a few people together, of course you have more money to spend and more power, and you can look for better horses.

“We do have one syndicate, which is named Equos. It’s very public because it belongs to somebody that runs the only racing paper in Italy. But nobody emulated that, so far at least. Italians are proud to be THE owner, and they don’t feel like being ONE of the owners. There are horses in partnership, but it’s not the norm.”

SCANDINAVIA

Norway does have company-regulated syndicates, but there are some operating on a private level.

“The main reason is that Norwegian rules and regulations do not allow ownership of racehorses to be defined as a business,” says Marianne Ek of the Norwegian Jockey Club. “It has to be taxed as private. This means that there are no incentives for companies to offer this service.

“The industry is constantly working towards our politicians to try to change this, but no luck so far.

“This does not mean that we don’t have syndicates and shared ownerships, but they are set up either by the owners themselves or the trainers.”

In Sweden and Denmark, syndicates are allowed to trade as businesses. Also, there are some companies that specialise in putting syndicates together and running them for a fee. 

CONCLUSION

As noted at the start, this is by no means a thorough investigation of shared ownership from the perspective of all stakeholders in all regions—lengthy and all as it is.

It is evident though that while some jurisdictions are more open to shared ownership than others, for a variety of reasons, there is a growing acknowledgement that for trainers, and thus the industry, the model has far more upside than any perceived negative once all stakeholders are protected by watertight regulation and rigorous oversight.

Make it as easy as possible, and make it attractive. After that, the smiles will go miles.

Smaller nations - the challenges facing trainers in Denmark, Poland and Spain

In the last issue, we featured a table of champion trainers and jockeys across Europe, compiled by Slovakia’s Dr Marian Surda. In this one, we have selected three of those champion trainers—those of Denmark, Poland and Spain—and tried to find out a little more about them and what it is like to be at the top of the training tree in their respective countries. While there is plenty of positivity and success to report, the challenges of sustaining viable businesses in the ‘smaller’ racing nations of our region, even for those at the top of their profession, are evident. It is a salutary finding that two of the three are looking to move on from the countries in which they have made their names.

Of our chosen trio, Guillermo Arizkorreta was the most highly ranked (by earnings), finishing 7th of 19 with earnings of €886,250 achieved through 61 winners at a strike rate of 19.3%. Niels Petersen not only finished 9th with his €311,537 in Denmark, but he also finished 8th as champion in Norway, with a further €443,856. And Cornelia ‘Conny’ Fraisl, one of only two females on the list, came in at No 14, earning €131,791 from her 50 wins in Poland.There are many similarities between the three. All happen to be of a similar ‘vintage’, being in their late 40’s or 50’s. 

Denmark has the fewest horses in training but has ready access to those trained in neighbouring Sweden and Norway. The number of trainers among whom these horses are divided are roughly comparable, as are the numbers of their owners. There is some disparity in prize money, with Poland some way adrift of the other two countries. None has a thriving thoroughbred breeding industry, producing limited numbers of foals and therefore relying on foreign-bred imports and foreign-trained runners to achieve the near-identical average field sizes of eight runners per race.

Denmark has one thoroughbred-only track (Copenhagen’s Klampenborg) and three dual gallop and trotting courses. In Poland, Sluzewiec—the main track at the country’s capital—is joined by three others, including Wroclav (where most Polish jump races are run) and the seaside track at Sopot. Spain has four traditional tracks, headed by La Zarzuela in Madrid and, in addition, has three beach racecourses and two ‘pop-up’ tracks.

NIELS PETERSEN

Niels Petersen can claim a unique achievement among current European trainers, in that he is Champion Trainer not only in Denmark, but also in Norway. While Petersen was born and raised in Denmark, he has lived in Norway for the past 25 years, from which base he has stewarded a stellar training career. He has earned the title of multiple champion trainer in all three Scandinavian countries, with combined annual prize money often exceeding €1M and peaking at around €1.7M. Over the years, he has garnered 788 winners in Scandinavia, at a strike rate of around 16%.

Petersen is a prolific winner of Scandinavia’s richest race, the Group III Stockholm Cup International. Square de Luynes ran up a hat-trick of wins.from 2019 to 2021, and Bank of Burden was a four-time victor in a long career. “My most consistent horse was probably Bank of Burden, but my best horse has been Square du Luynes. The Racing Post called him ‘Frankel of the Fjords’”!

Asked for his view of the best trainers in Europe, he says, “People like to say it’s a numbers game, and of course it is, and I know they have the firepower; but the way Aiden O’Brien and John Gosden place their horses, and the level they maintain year after year is just amazing and fantastic to watch. And I greatly admire Karl Burke. To have bounced back and actually raised his game, as he has, after all he’s been through…”.

As for the riders: “Frankie Dettori is special, of course, and I think William Buick, whom I know very well, is a fantastic jockey”. And turning to racetracks: “Ascot and Longchamp are absolutely fantastic tracks, and here in Scandinavia, Bro Park is very level and fair”.

Petersen’s move to Norway was by way of circumstance, not planning. Having completed his education and military service, he worked in Baden-Baden, (alongside friends who included jockey William Buick’s father) for a couple of years, before returning to his homeland, where he suffered a serious riding accident. Forced to seek work opportunities which did not involve riding, his knowledge of the German language came in handy, and he was asked to accompany Scandinavian-trained horses when they raced in Germany. There he met a Norwegian trainer who invited Petersen to join him in Norway to help train his jump horses.  

Last year and the year before, Petersen operated a satellite yard in Denmark, (just as once he did also in Sweden). Around 15 of his 55 horses were based at Klampenborg racecourse, and in both those years he claimed the Danish championship. However, despite that success, adverse exchange rate movements have led him to abandon the Danish base. “The Danish customers actually preferred to put the horse up with me in Norway. I haven’t lost any clients, and all their horses I have with me in Norway now.” 

Petersen is quick to praise the integrated race planning across the Scandinavian nations, making it practicable for trainers to map out campaigns for their horses. So, for example “if you have an outstanding miler, you can target all the big mile races, more or less.”

Securing owners in any one country is challenging enough—how does Petersen approach the task of finding owners in three countries? He is clear that the trainer’s job is not simply to train the horses—the social component is also vitally important. For example, the path to Dubai for its Carnival is a well-trod one—its purpose for Petersen being as much to enrich social relations with and amongst his owners as the pursuit of prize money. 

“I’ve got to make people enjoy the hobby I can provide them with. You do sacrifice a lot of time in doing that. But when you’ve sat on the beach and shared a bottle of wine in your swimming trunks, you become better friends!” 

The travel and the socialising place a premium on having excellent staff back at base and has been fortunate to have had a long-standing assistant in the business in the shape of his elder sister. “I make sure that my staff are well paid, and I’m strict in observing proper working hours. It has become more difficult to find good staff, but word of mouth has ensured we have an excellent team, including a number from South America”.

Petersen has noticed a reduction in horses in training in all three countries. “I’m a bit pessimistic as to the future of racing here, especially in Norway, because our government is not supporting the industry at all. It classifies it as a hobby and, unlike in Sweden and Denmark and elsewhere, you cannot own horses as part of a business. It means owners have to pay 25% VAT on top of imports, which they can’t get back.”  

Dubai’s allure is, of course, all the greater in the contrast it provides to the long, harsh Scandinavian winters. Petersen rues the fact that, from November to April, the Scandinavian climate renders virtually impossible the effective preparation of horses and, despite his huge success there, he has an eye out for opportunities abroad. “I would like to say I’m not looking for something outside, but I am. I live and breathe Scandinavian racing, but do I see myself here in five years’ time? I don’t think so. I don't see myself being here in five years’ time. I'm only 51 years old—not even at my peak—and I want the opportunity to challenge myself where I know I should be: on the bigger international scene”.

Until then, Scandinavia has given Petersen many special memories. What was his best day? “In Denmark, on Derby Day 2021, I had runners in seven races, and I won all seven of them!” If Square de Luynes was ‘Frankel of the Fjords’, then, after that ‘magnificent seven’, one could almost be forgiven for dubbing Niels Petersen ‘Frankie of the Fjords’.

CONNY FRAISL 

Fraisl’s rise to the top in Poland has been meteoric. Her first year with a public trainer’s licence was as recent as 2020, when, with 44 winners, she finished second in the trainers’ table. Two years later, she was crowned Champion, with 50 winners. Fraisl is alone among our trio in concentrating almost exclusively on Arabian, rather than thoroughbred racing.

“I was born in beautiful Salzburg, Austria”, she explains. “My grandparents had a little farm and, when I was three, my dad bought me my first pony. It was a ‘typical’ stubborn Shetland Pony; and once I’d landed on the ground several times, I asked my dad to ‘sell this pony and buy me a guinea pig’!”

But the lure of riding returned a decade later. “Close to the place I lived, there was a training stable for trotters where I spent every free afternoon, all my holidays from the age of 13. Racing always was fascinating for me. Flat racing In particular but, due to the fact that there was no flat racing stable in my area, I stayed the next seven years with trotters. But I always had an eye on flat racing and, in 1996, when I moved from Salzburg to Vienna, I was finally close to a racetrack where regular flat races were held. So, I made contact with one of the trainers, started to ride regularly in daily training there, gained my amateur licence and bought my first own racehorse.”

“I had the possibility of riding work in Florida for several weeks, and I could learn a lot about starting young horses there. During my earlier days in the trotting stable, I learned a lot about intensity of training, interval training, feeding and the general needs of racehorses”.

As an amateur, Fraisl notched up around 25 winners in Austria and Hungary, where she rode for two seasons for different trainers. Turning professional in 2006, she has amassed 208 winners in the saddle to date, riding in countries as far afield as Malaysia.

For her training career, Fraisl moved to Poland, her then-partner’s homeland, where she set up a private breeding and training facility in Strzegom, not far from Wroclav. “At the beginning, we had in training only homebred horses, thoroughbreds. Step by step, one by one, came some Arabians from Austria, Germany, Sweden.... and when they started to win more and more races. Owners from different countries recognised the job we were doing and sent us more and more Arabian horses to be trained in Poland. Today, she has some 80 boxes and 40 places for youngstock. She is an advocate of turnout for horses’ well-being.  “Twenty-five huge grass paddocks can be used all year round and all of our horses—including the racehorses—enjoy several hours outside every day. This is the most positive aspect for mental health. We also have an indoor arena and a horse walker as well as many possibilities to ride out into fields and forest to create the most individual training for our horses as possible”.
These days, Fraisl continues to ride out for nearly all the lots. “This is the best possibility for me to see how the horses in training work, how they behave—simply to ‘feel’ them”.

However, in Fraisl, we find another champion trainer wanting to move on from the country of their triumphs. “Actually we are dramatically reducing the number of our horses, and we are not accepting new horses and owners. The reason is that I am leaving Poland soon and will stop my job as a trainer here”. 

Fraisl cites a multitude of reasons for this bombshell decision which, she says, she has taken after lengthy consideration. “The number of foreign Arabian horses—as we mainly have them in training—is also getting smaller and smaller. This means that we are forced to enter three, four or five horses from our stable together in one race, or that race will be cancelled. This makes no sense for us and our owners any more”.  

Stagnant prize money and rising costs (of staff, transport, feed, bedding and veterinary and blacksmith services) are another factor. In addition, “there is a big lack of work riders. Most trainers work with a handful of enthusiastic amateurs, mainly young girls, who come to ride some lots before school or study or during holidays”. Fraisl also rues the talent drain of the best jockeys in Poland to other countries. She claims that drug and alcohol misuse is a real issue amongst riders and also that black-economy practices are common in the capital, with staff being employed without legal papers or insurance. “We have all our staff employed on a legal basis, and this is why we are the most expensive stable in Poland. We are already tired [of] explaining to the potential new owners why the prices of others are much lower—that's why we finally decided to close our training stable”.

These points were put to the Polish Jockey Club (PJC) racing secretary and the EMHF executive council member, Jakub Kasprzak. Kasprzak points to the fact that Poland is not alone in facing economic challenges, with high inflation being experienced generally across the continent. “It is true that prize money has not risen for some years, but it still compares favourably with that in, for example, Czechia or Slovakia. We are currently trying to support breeders and owners of Polish-bred horses. We have put in place a five-year programme to help this group of people. Ms Fraisl’s yard has 95% foreign-bred horses, so she is unable to participate in that programme. We have been paying transport only to horses to travel to Sopot (just four days’ racing per year) because there are no horses in training within 100km of that racecourse.”

“It is true that Polish riders, of all levels of ability, will often seek happiness abroad. But a shortage of racing staff is something that is being experienced throughout Europe. We are now seeing many staff coming from countries such as Kyrgyzstan and Kazakhstan. However, I don’t recognise her point about insurance and illegal workers. Every rider MUST have official insurance to be licenced. We at the PJC are very exacting about it. And as to drug and alcohol problems, every rider has a medical control before the start of a race. If the medical officer sees anything incorrect, he will report it to the stewards. Two years ago, one rider was suspended for one year for being drunk on race day”.

Where will Fraisl relocate to? “Time will tell. I hope to find a nice place where I can continue my work with Arabian horses.” 

Fraisl has not been averse to sending horses abroad to compete ‘whenever it makes sense’. Indeed it has been the forays abroad that have provided her with her most treasured racing memories. “As key moments, I would mention the experience [of taking] part and finishing fifth in the UAE President Cup - UK Derby in Doncaster this year with Bahwan and especially our first Group winner last year in Jägersro, Sweden. For me as a trainer, this was the first Group race abroad. For our young stable jockey it was the first big chance to ride a Group race and show his talent abroad so we said ‘let's go and try’. We had no idea how the colt would do on a dirt track and without the whip (in accordance with the rules in Sweden). In the event, it was the first Group win for me as trainer, for our jockey, and for the breeder....it was an unforgettable day for all of us”.

GUILLERMO ARIZKORRETA

One man has enjoyed a stranglehold on the Trainers’ Championship in Spain for over a decade. Guillermo Arizkorreta first topped the table in 2012 and has remained there ever since. 

By contrast with the other featured trainers, Arizkorreta trains at shared facilities, with some 25 others, at the La Zarzuela racetrack, very close to Madrid. It helps contain costs and has in turn contributed to the fact that Arizkorreta’s owners have enjoyed an enviable return on their annual costs, of over 75%. “It is very easy for the trainer. The owner pays €200/month to the racecourse, and it includes stabling, water supply, electricity, use of gallops, etc. Overall, having a horse in the yard costs around €1500/month, all included. It means that it is not that difficult to cover the cost of having a racehorse. On average, my horses have earned €13.500/year since I started”.

His operation supports some 70 horses in training and a workforce of around 25. “We have very nice staff, from many countries: Germany, Chile, Czech Republic, Italy, Nicaragua, Bolivia. As everywhere, there is a shortage, and it is not easy to find good riders. We have around 17 full-timers who work approximately 40 hours a week, a couple of part-timers, and some jockeys who are self-employed. The staff that work full-time work one weekend in two and the same for the evening stables. The basic wage for a full-time rider is around €19.000/year”.

“I started in a pony club in Oiartzun (close to San Sebastian) which was owned by a racehorse owner. There I met (four-time French Champion jockey) Ioritz Mendizabal, who had a keen interest in racing; and we started to ride racehorses in our local track in San Sebastian. From then on, I started following Spanish racing, and afterwards I started to follow racing and breeding around the globe, which became my passion”.

Arizkorreta singles out three key events in his rise to the top. “First, being able to compete in the FEGENTRI series as an amateur rider opened my eyes, and I was lucky to ride in many countries. Secondly, after finishing my degree, I spent nearly six years working as [an] assistant in the UK to Mr Cumani and in France to Mr Laffon Parias; and I learned a lot with them. 

“Lastly, Madrid racecourse was closed between 1996 and 2005, and I was lucky to be ready to start my career at the same time as the racecourse reopened. I was known as an amateur rider in Spain, and all the background from my experience abroad helped me a lot to get some clients in very exciting times”.

“We have won 878 races from 4,450 runners. In Spain, we have won all the major races and probably our biggest achievement abroad was to win a Gp3 and a Gp2 on the same weekend in Baden Baden in 2021”.

Loyal support from some of the country’s biggest owners has been a hallmark of Arizkorreta’s career. “I have a good bunch of owners. The majority of them have been with the yard for a long time. At the moment, we have around 20 different ownership entities—33% sole ownership and the rest partnerships. The majority of them used to come racing when they were children and have a good knowledge of the sport”.

Arizkorreta has not been shy of campaigning his horses abroad and has reaped healthy rewards, capped by that dual Group-winning day in Germany. “Since I started, I have always tried to race as much as possible abroad. We have had 112 winners abroad—mainly in France, but we have also won in Dubai, Germany, Morocco and Switzerland; and we have had runners in Saudi, Sweden, UK, and Italy”.

“I feel we have done pretty well abroad, and in the right races, our horses are usually competitive”.  

The trainer has much that is positive to say about racing in his country. “Madrid Racecourse is our ‘shield’, classified, as it is, as a monument. It is a fabulous racecourse, with lovely stands, a good turf track and a good crowd of people every meeting. It is very close to the city centre and is a track definitely worth visiting. Prize money could be better for the big races but in general is good, especially for the low-grade races. Being close to France helps us find suitable races for some horses”. 

As to what could be improved, Arizkorreta would welcome improved planning of the race programme and greater unity between trainers, jockeys, and owners to “push in the same direction and to improve the basics of our industry”. And financial structures also mean that there is not the opportunity to access horse walkers or equine swimming pools.

All in all for Arizkorreta, the future, if not stellar, looks stable. “I think in five years’ time we will be in a similar position. Things could be much better but, realistically, with politicians not giving us the tools to develop the betting and our industry; it is hard to imagine an improvement in the short term. We need them to make a long-term plan for racing and breeding and to consider it as an industry that can create wealth and employment in many areas. Since 2005, the ruling government has helped us with prize money, which covers nearly all the races run in the year; and I see no reason why it should change, especially in Madrid.     

“We have some lovely racecourses, which are always attended by a good crowd. In our biggest racecourse in Madrid, the weather is usually lovely, and it is becoming very popular in the city. There is scope to improve in many areas, and I can see it being one of the nicest racecourses in Europe. San Sebastian needs more support from the local government, but it is a historic racecourse in an amazing city. And I hope Mijas racecourse will reopen at some point”! 

It was heartening to find that at least one of our ‘smaller nations’ champion trainers shows no signs of wishing to leave the country. 

Amy Murphy – Thinking Outside the Box

Article by Katherine Ford

“I’m a bit choked up; this horse means the absolute world to me…” Amy Murphy was close to tears at Auteuil in March as she welcomed stable stalwart Kalashnikov back into the Winners’ Enclosure with Jack Quinlan aboard. It was a first success in almost four years for the ten-year-old, although the intervening months had seen the popular gelding performing creditably at Graded level in campaigns interrupted by injury. Connections pocketed €26,680 for the winners’ share of the €58,000 conditions hurdle; but the satisfaction far surpassed the prize money. 

“An awful lot of blood, sweat and tears have gone into getting him back, but don’t get me wrong: if at any point we thought that he wasn’t still at the top of his game, we’d have stopped because he doesn’t owe us anything.” Runner-up in the Supreme Novices’ Hurdle at the 2018 Festival and a Grade 1 winner at Aintree the following season, Kalashnikov put Amy Murphy—with her refreshing enthusiasm and undeniable horsemanship—on the map from the start of their respective careers. 

“He is very much a people’s horse. He was campaigned from the early days at the highest level, and he had some real good battles as a young horse; and I think that those types of horses that don’t go down without a fight, people lock onto them and follow them.”

From veterans to juveniles

Equuis Photography / Jason Bax

While the achievement of keeping a ten-year-old on form and identifying a winnable race at Auteuil for his French debut is considerable, the success was all the more notable as it came just three days after Myconian had earned connections €15,000 for victory in the Prix du Début at Saint-Cloud—the first juvenile contest of the Parisian season. It is rare to find a trainer with success at both ends of the age spectrum, in two different disciplines, but when you add in the fact that Amy Murphy had crossed the Channel to complete this unusual double, it demonstrates a laudable versatility. 

“We try and work with everything we get sent. We’re in a fortunate position where we’ve got the best of both worlds with lots of lovely young horses; but Kalashnikov, Mercian Prince and some of the old brigade have been with us since we started. I started training six years ago, and they were two of the first horses in my yard so they’ve been a big part of my career and still are.” 

Twelve-year-old Mercian Prince has racked up a total of 13 wins for Amy since arriving in her fledgling yard from France in 2016, with three of these coming in the past 12 months and including one in Clairefontaine last summer. As with Kalashnikov, patience has reaped rewards with this veteran. 

“Mercian Prince is very tricky to train at home—he has a mind of his own, and everything’s got to be on his terms. We do lots of different things with him. He will go three or four times during the year to the beach at Holkham, which is about an hour down the road. It keeps him mentally active. I’m a big believer in freshening them up. I like to string a couple of races together and then give them a week or ten days out in the field at the farm—things like that. It’s fine if you’ve got two-year-olds and it’s a short-term game; but with older horses that you know are going to stick around, you’ve got to keep them fresh.”

From pony-mad to the youngest trainer in Newmarket

Ambitious and determined, Amy Murphy spent her childhood on her father’s Wychnor Park Stud in Staffordshire. “My dad bred National Hunt horses as a hobby. I always had ponies and hunted and showjumped until I was about 16; then I started riding out for local trainers and got bitten by the racing bug. I spent all of my weekends and holidays riding out for as many people as would let me in. My dad wouldn’t let me leave school without any qualifications, so I went to Hartpury College and did a diploma in equine science. The day after that finished, I was in a racing yard.” 

After a stint with Nicky Henderson, Amy’s now-characteristic adventurous spirit led her to Australia and an educational season with Gai Waterhouse. “Australia was where I learnt more about spelling horses. Their horses will only have three or four runs together and their seasons are split up so they can campaign them with breaks in between the different carnivals. Gai is obviously brilliant with her two-year-olds and does lots of stalls work with them, and that was another important thing I learnt with her.” 

On returning to the UK, Amy joined Tom Dascombe as pupil assistant at Michael Owen’s Manor House in Cheshire, which opened the doors to France for the first time, overseeing his satellite base in Deauville during a summer. Her racing education was completed with four years at Luca Cumani’s stable in Newmarket before setting out on her own in 2016, at age 24—the youngest trainer in Newmarket. 

“One of the biggest things I learnt from Luca was making sure a horse is ready before you run. As you become a more mature trainer, you relax more into it; you learn that patience pays off. If you think something needs a bit more time or something’s not quite right, then nine times out of ten, you need to be patient.” 

Patience is a virtue

Amy with Pride Of America & Lemos with Miss Cantik.

Amy Murphy may have learnt patience with her horses, but she is impatient with a system that she has had to seek and find alternative campaigns for her horses due to low prize money in the UK. “As William Haggas said to me the other day, I’ve got off my rear end and done something about the situation.” She continues, “It’s very hard to make it pay in England, sadly, so it’s either sit here and struggle or do something outside the box.” 

Amy’s first Stakes success came in France in just her second season training, thanks to £14,000 breeze-up purchase Happy Odyssey, winner of a juvenile Listed contest at Maisons-Laffitte and who quickly added more profit by selling for €300,000 at Arqana’s Arc Sale just days later. “From very early on, we’ve targeted France. To start with, it was just the black-type horses; but once I got to know the programme a bit better, we started to bring a few of the others across too.”

The ”we” referred to includes Amy’s husband, former Brazilian champion apprentice Lemos de Souza, whom she met when working for Luca Cumani and who now plays a vital role at Amy’s Southgate Stables. “He’s a very good rider and a very good judge of a horse, and is a great asset to have with the two-year-olds. It’s nice having someone to work with and bounce ideas off. He has travelled all over the world—Dubai, Japan, Hong Kong—for Luca Cumani with all of his good horses.”

French flair

Tenrai & Jade Joyce.

Last year, the pair widened their horizons further with the decision to take out a provisional licence in France, renting a yard from trainer Myriam Bollack-Badel in Lamorlaye. “We were going into the complete unknown. My travelling head girl Jade Joyce was based out there along with another girl; and we basically sent out twelve horses on the first day and between them, they had a fantastic three months. The two-year-olds were where our forte lay and what we tried to take advantage of, whereas we had never had horses run in handicaps in France. So, we had to get the older horses handicapped, and the system is completely different. 

Amy with racing secretary, Cat Elliott.

There were plenty of administrative errors early on, as my secretary Cat Elliot was doing everything from in Newmarket; so there were plenty of teething problems and plenty of pens being thrown across the office… For example, I didn’t know you couldn’t run a two-year-old twice in five days, so I tried to declare one twice in five days … little things like that. It was all a learning process, like going back to square one again.”

The operation was declared a resounding success, with eight wins and 15 placed runners during the three-month period, amassing a hefty share of the €276,927 earned by the stable during 2022 in France. Among the success stories, juvenile filly Manhattan Jungle was snapped up by Eclipse Thoroughbred Partners after two wins at Chantilly and Lyon Parilly and was later to take Murphy and team to Royal Ascot, the Prix Morny and the Breeders’ Cup. Meanwhile, another juvenile filly, Havana Angel, earned black type in the Gp.3 Prix du Bois, entered Arqana’s Summer Sale as a wild-card and changed hands for €320,000. 

The sole regret is that France Galop only allows trainers one chance with the provisional licence. “We tried to apply again this year but sadly got turned down. Moving over full time is not out of the question in the future.” 

Vive la Difference

During her stint at Lamorlaye, Amy had the chance to observe some of the French professionals; and although she stresses, “I wasn’t up at Chantilly so didn’t get to see the likes of André Fabre…,” she also notes, “The gallops men would be very surprised by how quick our two-year-olds would be going regularly. The French seem to work at a slower pace, whereas we are more short and sharp; and we use the turf as much as we can. We would work our two-year-olds in a last piece of work with older horses to make sure that they know their job.” 

Impressed by the jumps schooling facilities in Lamorlaye, Amy was also complimentary about other aspects of the training centre. “I like the way that you can get the stalls men that work in the afternoon to come and put your two-year-olds through in the morning. That’s all very beneficial to both the horse and to the handlers because they know each other. Another big thing which I love over in France is that when the turf is too quick, they water it so that you can still train on it in the mornings, even at the height of the summer.”

Even without the provisional licence, Amy Murphy’s name is still a familiar sight on French racecards. At the time of writing in late May, her stable has earned €117,446 in prize money and owners’ premiums in 2023, from 18 runners of which four have won and eight placed. 

To reduce travel costs, organisation is key. “I had a filly that ran well in a €50,000 maiden at Chantilly recently, and she travelled over with a filly that ran and won at Saint-Cloud three days later. They were based at Chantilly racecourse for the week and moved across to Saint-Cloud on the morning of the race and then came home together on Friday night. It takes a bit more logistics but financially it makes sense to send two together.” As for the owners, they have made no complaints about seeing their horses race further afield. “Plenty of my owners have been over to France; they love it. I haven’t had one person say they don’t want to go to France yet, anyway!”

Defending an industry

Closer to home, a subject dear to Amy’s heart is horse welfare and the image of racing. On her social media accounts, she promotes the cause and has invited the public to visit her stable to see for themselves the care that racehorses are given. “I’ve had a couple of contacts but nowhere near as many as I’d like. As an industry, we have to show that this image that so many people have of racing is just not true. The only way we can do that is by getting people behind the scenes and letting them see just how well these animals are loved and cared for by all of the girls and guys in the yards. Events like the Newmarket Open Day, when we get thousands of people in to visit the years, are the kind of thing that we need to keep pushing. I want to be in this sport for a long time, so I want to do anything I can to help promote it.” 

With advocates like Amy and a generation of motivated young trainers, the sport of horse racing can count on some highly professional, hard-working and modern ambassadors, in the UK, France and beyond. 

Assessment of historical worldwide fracture & fatality rates and their implications for thoroughbred racing’s social licence

Article by Ian Wright MRCVS

Racing’s social licence is a major source of debate and is under increasing threat. The principal public concern is that racing exposes horses to significant risk of injury including catastrophic (life-ending) injuries of which fractures are the commonest cause. The most recent studies in the UK indicate that fractures account for approximately 75% of racecourse fatalities. Recent events highlight the need for urgent stakeholder discussion, which necessarily will be uncomfortable, in order to create cogent justification for the sport and reliant breeding industry.

A necessary prelude to discussion and debate is an objective assessment of risk. All and any steps to reduce risks and mitigate their impact are important and must be embraced by the horseracing industry (and quite possibly all other horse sports). To begin this, a here and now assessment is important: put simply, does the price paid (risk) justify the benefit (human pleasure, culture, financial gain, employment, tax revenue, etc). Objective data provides perspective for all interested parties and the voting public via their elected representatives, who ultimately provide social licence, with other welfare issues—both human and animal—on which society must pass judgement. 

The data in Tables 1 to 12 report a country by country survey of fracture and fatality rates reported in scientific journals and documented as injuries/fatalities per starters. It may be argued that little of the data is contemporary; the studies range from the years 1980 to 2013. However, the tabulated data provided below is the most up to date that can be sourced from independently published, scrutinised scientific papers with clear—albeit sometimes differing—metric definitions and assessable risk rates.

In assimilating and understanding the information, and in order to make comparisons, some explanatory points are important. The first, and probably the most important, is identification of the metric. Although at first glance, descriptor differences may appear nuanced, what is being recorded massively influences the data. 

These include fatality, catastrophic injury, fracture, orthopaedic injury, catastrophic distal limb fracture, fatal musculoskeletal injury, serious musculoskeletal injury, and catastrophic fracture. The influence of the metric in Japanese racing represents the most extreme example of this: ‘fracture’ in the reporting papers included everything from major injuries to fragments (chips) identified after racing in fetlocks and knees, i.e. injuries from which recovery to racing soundness is now an expectation.  At the opposite pole, studies in other countries document ‘catastrophic’, i.e. life-ending fractures which have a substantially lower incidence. The spectrum of metric definitions will all produce different injury numbers and must be taken into account when analysing and using the data. 

Studies also differ in the methods of data collection that will skew numbers in an undetermined manner. Some only record information available at the racecourse, others by identifying horses that fail to race again within varying time periods, horses requiring hospitalisation following racing, etc. The diagnostic criteria for inclusion of horses also vary between reports: some document officially reported incidents only, some are based only on clinical observations of racecourse veterinary surgeons, while others require radiographic corroboration of injuries. 

From a UK perspective, the data is quite robust in concluding that risks differ significantly between race types. The majority of fractures that occur in flat racing, and between obstacles in jump racing, are the result of stress or fatigue failure of bone. They are not associated with traumatic events, occur during high speed exercise, are site specific and have repeatable configurations. In large part these result from a horse’s unique athleticism: in the domesticated species, the thoroughbred racehorse represents the pinnacle of flight-based evolution. Fractures that result from falls in jump racing are monotonic—unpredictable, single-event injuries in which large forces are applied to bone(s) in an abnormal direction. 

This categorisation is complicated slightly as fatigue failure at one site, which may be bone or supportive soft tissue, can result in abnormal loads and therefore monotonic fracture at another. The increased fracture rate in jump racing is explained in part by cumulative risk. However, it is complicated by euthanasia of horses with injuries with greater post injury commercial value and/or breeding potential that might be treated. Catastrophic injuries and fatality rates in NH flat races are most logically explained by a combination of the economic skew seen in jump racing and compromise of musculoskeletal adaptation.

Racing surface influences both injury frequency and type. Studies in the UK have consistently documented an increased fatality rate and incidence of lower limb injury on synthetic (all weather) surfaces compared to turf.  Although risk differences are clear, confounding issues, such as horse quality and trainer demographic, mean that the surface per se may not be the explanation. In the United States, studies reporting data from the same geographic location have produced mixed results. In New York, these documented greater risks on dirt than turf surfaces; while a California study found no difference, and a study in Florida found a higher risk on turf. A more recent study gathering data from the whole of the U.S. reported an increased risk on dirt surfaces. Variations in the nature of injury between surfaces may go some way toward explaining fatality differences.

Much has been done to reduce recognisable risk factors particularly in jump racing; but in the UK, it is likely (for obvious data supported reasons) that it will come under the greatest scrutiny. The incidence of fractures and fatalities in flat racing are low, and the number of currently identified risk factors are high. Over 300 potential influences have been investigated, and over 50 individual factors demonstrated statistically are associated with increased risk of catastrophic injury. 

The majority of fractures occurring in flat racing (and non-fall related fractures in jump racing) are now also treatable, enabling horses to return to racing and/or to have other comfortable post-racing lives. 

The common public presumption that fractures in horses are inevitably life-ending injuries is a misconception that could readily be remedied. An indeterminate number of horses are euthanised on the basis of economic viability and/or ability to care for horses retired from racing. On this point, persistence with a paternalistic approach is a dangerous tactic in an educated society. Statements that euthanasia is ‘the kindest’ or ‘best’ thing to do, that it is an ‘unavoidable’ consequence of fracture or that only ‘horsemen understand or know what is best’ can be seen as patronising and will not stand public scrutiny. 

At some point, data to distinguish between horses euthanised as a result of genuinely irreparable injuries and those with fractures amenable to repair will become available. Before this point is reached, the consequences require discussion and debate within the racing industry.

Decisions on acceptable policies will have to be made and responsibility taken. In its simplest form, this is a binary decision. Either economic euthanasia of horses, as with agricultural animals, is considered and justified as an acceptable principle by the industry or a mechanism for financing treatment and lifetime care of injured horses who are unlikely to return to economic productivity will have to be identified.  The general public understands career-ending injuries in human athletes: These appear, albeit with ongoing development of sophisticated treatments at reducing frequency, in mainstream news. 

Death as a direct result of any sporting activity is a difficult concept in any situation and draws headlines. Removal of the treatable but economically non-viable group of injuries from data sets would reduce, albeit by a currently indeterminate number, the frequency of race course fatalities. However, saving horses' lives whenever possible will not solve the problem: it will simply open an ethical debate viz is it acceptable to save horses that will be lame? In order to preserve life, permanent lameness is considered acceptable in people and is not generally considered inhumane in pets. Two questions arise immediately: (i) How lame can a horse be in retirement for this to be considered humane? (ii) Who decides? There is unquestionably a spectrum of opinion, all of which is subjective and most of it personal. It will not be an easy debate and is likely to be complicated further by consideration of sentience, which now is enshrined in UK law (Animal Welfare (Sentience) Act 2022); but it requires honest ownership of principles and an agreed policy.

For the avoidance of doubt, while the focus of this article and welfare groups’ concerns are on racecourse injuries, those sustained in training follow a parallel pathway. These currently escape attention simply by being, for the most part, out of sight and/or publicity seeking glare. 

Within racing, there is unquestionably a collective desire to minimise injury rates. Progress has been made predominantly by identification of extrinsic (i.e. not related to the individual horse) risk factors followed by logical amendments. In jump racing (monotonic fractures), obstacle modification, re-siting and changing ground topography are obvious examples of risk-reducing measures that have been employed. 

In flat racing progress has involved identification risk factors such as race type and scheduling, surface, numbers of runners, track conditions etc which have guided changes. However, despite substantial research and investment, progress in identification of intrinsic (ie relating to the individual horse) risk factors is slow. While scientifically frustrating, a major reason for this is the low incidence of severe fractures: this dictates that the number of horses (race starters) that need to be studied in order to assess the impact of any intervention is (possibly impractically) high. Nonetheless, scientific justification is necessary to exclude a horse from racing and to withstand subsequent scrutiny.

Review of potential screening techniques to identify horses at increased risk of sustaining a fracture while racing is not within the scope of this article, but to date none are yet able, either individually or in combination, to provide a practical solution and/or sufficiently reliable information to make a short-term impact. It is also important to accept that the risk of horses sustaining fractures in racing can never be eliminated. Mitigation of impact is therefore critical. 

When fractures occur, it is imperative that horses are evaluated to be given the best possible on course care. This may, albeit uncommonly be euthanasia. Much more commonly, horses can be triaged on the course and appropriate support applied before they are moved to the racecourse clinical facility for considered evaluation and discussion. The provision of fracture support equipment to all British racecourses in 2022 marked a substantial step forward in optimising injured horse care.

Neither racing enthusiasts nor fervent objectors are likely to change their opinions. The preservation of social licence will be determined by the open-minded majority who lie between: it is the proverbial ‘man on the street’ who must be convinced. The task of all who appreciate horse racing's contributions to society and wish to see it continue is to remain focussed on horse welfare, if necessary to adjust historical dogmas, absorb necessary costs and to encourage open, considered, honest (factually correct) risks versus benefits discussion.

Warsaw finally hosts EMHF assembly and stewards' conference

Article by Paull Khan

It’s just possible that the main benefit of the EMHF to its racing administrator members is the social dividend. Many of us have been involved for a dozen years or more, and the bonds that have developed within our network allow easy and unhesitating communication whenever some international issue or other should crop up in our racing lives. This column’s regular reader will know that the EMHF seeks to enrich our members’ education by moving our biannual meetings around the region and combining them with attending the races in the host country. In this issue, following a successful gathering in Poland, we try to convey a little of the flavour of an EMHF General Assembly reunion.

Back in 2019, when we gathered in Oslo and memorably celebrated Norway’s exuberant May 17th National Day celebrations, it was announced that, the following year, we would reconvene in Warsaw. That was not to happen, due to COVID, and the next two years were Zoom affairs. When the pandemic’s grasp began to ease, the Polish plan was back on the table— only for the conflict in neighbouring Ukraine to put an end to those hopes. Ireland manfully stepped in to host us at The Curragh in 2022; and so, when our party—of 48, from 19 countries—finally descended on the Polish capital on the middle weekend of May, there was a palpable feeling of relief.

By common consent, it was worth the wait.

Following the pattern introduced in Ireland, the event was split across two days. The first afternoon was devoted to all the things that one associates with a General Assembly: financial, membership and administrative matters, together with updates, from each member country present, on the state of racing in their respective nations, as well as from various relevant committees and sister organisations. The hosts also gave a colourful account of the rollercoaster that is the history of racing in their homeland.

We were pleased to welcome, once again, representatives of the European Federation of Thoroughbred Breeders’ Associations (EFTBA) and the European and African Stud Book Committee (EASBC). Because the EMHF has long taken the view that we in the equine sector should avoid operating in isolation, and instead benefit from cross-fertilisation of knowledge and ideas, these organisations, together with the European Trotting Union (UET) and European Equestrian Federation (EEF), are standing invitees to our General Assemblies.

After an excellent dinner that evening at the elegant Rozana restaurant in the Konstancin area of the city, our second morning was wider in its scope, and the floor was given to a number of experts who presented on a range of matters of current interest or concern. 

Police involvement in French racing

Those who followed the high-profile rape allegations against Pierre Charles Boudot or the arrests of the Rossi trainer brothers might have been struck and intrigued by the closeness of the involvement of the French police. Henri Pouret, EMHF executive council member for France, explained how there is a branch of the national French police force—the Service Centrale Courses et Jeux—dedicated to racing and gaming matters. No licenced or registered participant in French racing—be they owner, trainer, jockey or breeder—is allowed to participate unless their registration is authorised by the ‘racing police’. Then, once registered, if such an individual becomes subject to judicial proceedings, the racing police may require France Galop, or its trotting equivalent, Le Trot, to withdraw or suspend their licence. This is not just a theoretical power—on no fewer than 25 occasions did they do just this in the course of last year.

It is only for the past three years that doping a racehorse has been a criminal act in France. It seems likely that the racing police will play an ever more central part in the regulation of French racing.

FEGENTRI and the International Pony Racing Championship

With EMHF’s formation last year of the European Pony Racing Association (EPRA) and the launch in 2023 of FEGENTRI’s Junior Championship, never has there been a more opportune time to explore and develop the relationship between the amateur and professional communities in European racing. It was therefore a pleasure to receive FEGENTRI’s secretary-general, Charlotte Rinckenbach, to explain the work and relevance of her organisation.

FEGENTRI, the international federation of gentlemen and lady riders, has a history that stretches back to 1955. It is therefore longer established, not only longer  than the EMHF, but also longer than both the IFHA and the Asian Racing Federation. It organises amateur races around the world, across four main championships, and prides itself on providing a distinct and effective route by which to involve people in our sport from diverse walks of life.

FEGENTRI Junior is the first international pony racing championship of its kind. It has started in a modest way, with four countries each fielding two young riders, aged between 14 and 16 years. (The competition, which has the full support of the EPRA, is open to those of 12 years and over; but no-one younger than 14 was chosen this year). Their level of experience varies greatly—some have only ridden in a dozen races; others have 150 rides and over 50 winners under their belts. These eight trail-blazing youngsters have the wonderful opportunity of riding competitively in Florence, Bro Park, Chantilly, Livorno and Kincsem Park. And who’s to say that, from amongst them, we will not see a champion of the future?

Gene doping and its implications for EMHF members

‘Gene doping is not a rumour anymore’, was the stark opening warning from Dr Kanichi Kusano of the Japan Racing Association, one of the world’s experts in this sphere. He explained that the abuse of genetic therapies is a major threat to racing’s integrity. In the worst-case scenario, the heritable genome of a thoroughbred would be changed through genetic modification at the breeding stage—of the eggs, sperm or embryo. The good news is that, in this race, the ‘good guys’ are up with the pace, and already there are out of competition (OOC) tests for gene doping that are being deployed. 

Smaller countries, without extensive resources to direct towards research or detection, were advised to prepare by ensuring their rules adequately outlawed the practice and to publicise and start a programme of deterrent sample collection, followed by OOC testing as soon as the leading racing nations offer a suitable commercial service.

The World Pool

Tallulah Wilson, UK Tote Group’s head of international racing, spoke of the burgeoning impact of the World Pool and how EMHF countries could get involved through the World Tote Association (WoTA). World Pool, the Hong Kong-based system for commingling bets placed on key international races, is only four years old; but it has already demonstrated that races selected for inclusion enjoy a startling increase in pool betting turnover. 

Higher liquidity attracts the high-rollers and creates a virtuous circle from which the participating racecourses benefit, potentially boosting prize money. However, legislative restrictions in Hong Kong mean that the races included do not number in the thousands, or even hundreds. Just 25 race days, predominantly in Britain and Ireland, will form the 2023 roster. While this number is growing, the prospects of most EMHF member countries having a race included in the near term are only distant (although fresh ground has been broken this year through the inclusion—as a single race from a different country within a World Pool Day—of the German Derby).

However, Wilson’s message was that ‘everyone is welcome’ within WoTA. Member countries’ Tote operators were encouraged to apply to join, opening up the possibility of their punters being able to bet into the commingled World Pools and earning that pool operator and its racing industry a slice of the take-out.

Racing to school and National Racehorse Week

For over 20 years, a British programme has been introducing racing to schoolchildren, presenting aspects of their school curriculum through the lens of a visit to a racecourse, training yard or stud. John Blake, CEO of Racing to School, spoke of 16,000 children who attended such a course last year, instilling in many of them a positive sentiment towards the sport, which may hopefully translate in time into ownership or professional involvement. 

The third National Racehorse Week in Britain will take place in September, when racing yards and stud farms will open their doors to welcome members of the public. Over 10,000 took up the offer last year, of whom one-fifth were new to racing. 

At a time when our sport’s public image is under increasing pressure, these positive interactions with the public are initiatives which many member countries could look to replicate.

Racing at Sluzewiec 

With the business affairs completed, it was off to the races. The approach to Sluzewiec Racecourse is through a proud avenue of mature trees, and the whole expansive site was lush and green. The stands were indeed grand, completed, with unfortunate timing, in 1939—just before the onset of war. An attractive feature of the main grandstand is a sloping, stepless zigzag by which one ascends and descends from floor to floor. It makes for a photogenic feature—ideal for the fashion catwalks that are sometimes staged there.

The EMHF Cup was run over a mile for unraced three-year-olds worth €3,200. It attracted a field of eight runners. The winner, Sopot was one of only two Polish-breds, taking on horses foaled in Great Britain, France, Czech Republic and Ukraine.

The nine-race card was worth a total of €24,000. A mixed programme comprised thoroughbred, trotting and Arab races, from 1300m (6 1/2f) up to 2400m (1 1/2m). No race attracted fewer than seven runners and the largest field was 11. Interestingly, in an apprentice race, for riders who had ridden fewer than 25 winners, the whip was not allowed to be carried, let alone used.

Horserace betting is not ingrained in Polish society, and there was little evidence of avid form study, or raucous cheering. However, the crowd’s demographic was a revelation: it was hard to spot a grey hair, with patrons almost exclusively families or young adults. It made for a beguilingly relaxed atmosphere.

Our horizons have been broadened by the experience of witnessing racing in such diverse settings across the EuroMed region as Waregem, (Belgium), La Zarzuela (Madrid, Spain), Kincsem Park (Budapest, Hungary), Casablanca (Morocco), Leopardstown and The Curragh (Ireland),  St. Moritz (Switzerland), Bro Park (Sweden),  Hamburg (Germany), Marcopoulo (Athens, Greece),  Bratislava (Slovakia), Les Landes (Jersey, Channel Islands), Pardubice (Czech Republic), Ovrevoll (Oslo, Norway), Veliefendi, Istanbul and Izmir (Turkey), Cheltenham (Great Britain) and now Warsaw. 

Seeing the sport flourish in such varied surroundings brings home the need to do all we can to preserve racing in every country in which it currently takes place. Singapore’s decision to draw the curtain down on horseracing was such dispiriting news.  A broad and thriving base to our pyramid enriches us all.

First  EuroMed Stewards’ Conference

Few things in international racing excite as much comment and criticism as comparing decisions taken by stewards around the world. There is a constant cry for consistency in the rules that apply to the running of a race, in the way stewards interpret both the races and the rules, and in the levels of penalty handed down. Harmonisation of such matters is a real challenge, not least because there is nobody in horse racing that sets world rules; each national racing authority sets its own. But that is not to say that substantial efforts are not made constantly to improve things in this area. It is the very raison d’etre of the International Federation of Horseracing Authorities’ (IFHA’s), International Harmonisation of Racing Rules Committee (IHRRC), and is also the subject of much of the discussion at the International Stewards’ Conferences (ISC) that the IFHA has staged, roughly every two years, around the world. 

But these meetings must limit the numbers of delegates in attendance, and it is in practice that only the major racing nations benefit from being party to the discussions. For this reason, it was decided to stage a Stewards’ Conference for the EuroMed region and to welcome all EMHF member countries—large and small. This suggestion, proposed by Germany, was picked up with enthusiasm by Britain. Thus, it came to be that the day after the General Assembly, the BHA’s Brant Dunshea chaired the inaugural EuroMed Stewards’ Conference, which attracted a pleasing turnout of 30 delegates from 12 countries.

Joining from Australia via Zoom was Kim Kelly, who has for many years chaired both the IHRRC and ISC; he set the scene and placed this gathering into its global context. There followed a range of presentations, including the following.

Competency-based training programme

The job of the steward is high-profile, highly-charged and perpetually subject to criticism from both the media and the public. The BHA’s Cathy O’Meara described how Britain has recently introduced a competency-based training programme to ensure that its stewarding workforce, along with all raceday teams, is (and remains) up to the job. Through a combination of interactive on-line learning, shadowing, mentoring and more, stewards learn, and are then assessed on, race reading, the rules, enquiry training and report writing. And, once initial competencies are met, the learning journey is not over. All stewards will be required to complete continued professional development, where half of the content relates directly to their roles and half to general industry-related issues such as equine and human welfare. A next step will be to develop a module for the use of those in the industry, such as trainers and the general public. The BHA also has plans to offer to receive stewards from smaller racing nations to assist in their development.

Illegal betting

The EMHF’s equivalent in the Asian and Oceanian region, the Asian Racing Federation (ARF) and, in particular, Hong Kong, is on the front line in a battle against illegal betting. The ARF has established a Council on Anti-Illegal Betting and Related Financial Crime; and its chair, Martin Purbrick, joined us by video conference.

The stark facts are that illegal betting is growing much more quickly than legal betting and already represents the majority of online betting. Aside from the fact that illegal betting makes no contribution to racing, nor to society at large, through taxation, it is also intrinsically linked to race-fixing and organised crime. While Asia may be the historic hotbed of this activity, Purbrick cautioned that Asian illegal betting has already expanded into Europe.

Online betting is no respecter of national boundaries, and if we are to be successful in this war, it will require a joined-up, cross-border and multi-agency approach, involving governments, racing authorities, gambling authorities and the police. But we cannot leave it to these organisations alone—it is incumbent upon all of us to be aware of the risks of race manipulation and to whistle-blow if ever we encounter it.

Virtual stewards’ room

This column (April 2020) described a novel system of remote stewarding, witnessed by the author in Johannesburg. It looked forward to a day when Stewards are situated at a central location, away from the track, from which they communicate with the principals on-track and view video footage. This might be widely adopted, promising more consistent application of the rules and the opportunity for smaller countries to outsource their stewarding function to larger countries.

The Conference heard how this brave new world might just have moved a step closer. The BHA reported on a system first trialled in 2020 and prompted by the COVID outbreak. The pandemic created a situation in which there was a real risk of stewards being unavailable due to a requirement to isolate. In response, assistant stewards began working remotely, through video conferencing from their homes, but initially without access to the full range of views available to the stewards on-course. The BHA then set about developing a hub, away from the racecourse, which offered the full range of race replays. While it was considered there was still the need to have a senior person on the course, the hub provided resilience against absence, allowed stewards to officiate at afternoon and evening meetings on the same day, etc.

The trial has now been rolled out in Britain, such that all assistant stewards have the option to work from home, improving their work/life balance. Around 25 percent of fixtures are covered by the technology, and it is planned to expand this further in the future.

Anti-doping activities

It has long been appreciated that trainers, when racing in different jurisdictions, should, as far as is practicable, be assured of facing similar treatment regarding medication control. To that end, the European Horseracing Scientific Liaison Committee (EHSLC) was set up over 30 years ago and continues to lead on this area of racing administration in our region. The Conference heard how the EHSLC (which is comprised of the chief veterinary officer/anti-doping manager from the member countries, representatives of the national laboratories, which carry out regulatory work for those countries, specialist pharmacologists and senior administrators from the racing authorities)  has generated a significant amount of data relating to common use medications and has published detection times for many substances. The science underlying these data is rigorous and the subject of considerable review and has often been accepted by the wider global racing community, forming the basis of international screening limits.

Feedback on the inaugural EuroMed Stewards’ Conference has been universally positive, and there is much enthusiasm to make this a regular event, perhaps again being staged alongside our General Assemblies.

Train, Race, Recover and Repeat – How targeted nutrition can support the recovery process to optimise performance

Article by Dr Andy Richardson BVSc CertAVP(ESM) MRCVS

Introduction

Horses evolved as herd-living herbivores with a digestive tract designed to cope with a near continuous dietary input of forage in the form of a wide range of plant species. A large hindgut acts as a fermentation vessel where gut microbiota (predominantly a mix of bacteria, protozoa and fungi) exist in harmony with the horse in order to digest the fibre rich plant material.

Fibre is important to the horse for several reasons. The digestion of fibre releases energy and other key nutrients to the horse. Fibre also acts to provide bulk in the digestive tract, thus helping maintain the passage of faecal material through the system. Fibre also acts like a sponge to absorb water in the gut for release when required.

As horses became domesticated and used for work or sporting purposes, more energy-dense feeds in the form of cereal grains were introduced to their diet, as simple forage did not provide for all the caloric requirements. Cereal grains are rich in starch, which is an energy-dense form of nutrition. However, too much starch can cause problems to a digestive tract that remains designed for a pasture-based diet. The issues that can be caused by the trend away from a solely pasture-based diet can be digestive, behavioural or clinical.

Nonetheless, the combination of forage and cereal-based concentrates remains the mainstay approach for the majority of horses in training today, in order to maximise performance. A great deal of research and expertise are utilised by the major feed companies to ensure that modern racehorse concentrate feeds provide adequate provision of the major nutrients required and minimise unwanted effects of starch in the diet.

This article aims to discuss some scenarios where targeted or supplemented nutrition can act to help overcome some of the nutritional challenges faced by the modern horse in training, as they “Train, Race, Recover and Repeat.”

Equine Gastric Ulceration Syndrome (EGUS)

EGUS occurrence in racehorses is well documented, with prevalence shown to be over 80% in horses in training (Vatistas 1999). With a volume of approximately 2–4 gallons (7.53–15 litres), the stomach in horses is relatively small compared to their overall size due to its functional role in accommodating trickle feeding that occurs during their natural grazing behaviour. 

As a horse chews, it produces saliva, which is a natural buffer for stomach acid. When the horse goes for a period of time without chewing, the production of saliva ceases, and stomach acid is not as effectively neutralised. The lower half of the stomach is better protected from acid due to its more resistant glandular surface. The upper, or squamous, region does not have such good protection, however, and this can be a problem during exercise when acid will physically splash upwards, potentially leading to gastric ulceration.

In practice, this can presentrepresent a challenge for horses in training. Typically, they will be fed a concentrate-based feed in the early morning that stimulates a large influx of acid in order to help digest the starch. This may be followed by a period without ad-lib access to hay, thus reducing the amount of saliva subsequently produced to act as a buffer. When the horse is subsequently worked, there is a risk of acid damaging the upper squamous region of the stomach. There is some evidence to suggest that the provision of hay in advance of exercise may act like a sponge for the acid, as well as helping form a fibrous matt to minimise upward splash.

Gastric ulceration can go undetected in horses in training and may not lead to any obvious clinical signs. In other horses, it can lead to colic, poor appetite, dull coat and behavioural changes. In both scenarios, it is likely that the ulceration will have an impact on their performance, with decreased stride length, reduced stamina and inability to relax at speed all being possible consequences (Nieto 2009). Gastric ulceration can therefore have a significant impact on the ability of a horse to perform optimally day in day out in a training environment. This is exacerbated when ulceration leads to a reduction in appetite, with the obvious downside of a reduction in calorie intake leading to condition loss and further drop in performance.

This is an area where targeted nutrition has been clinically proven to play an important role. Ingredients such as pectin, lecithin, magnesium hydroxide, live yeast, calcium carbonate, zinc and liquorice have all been studied as having beneficial effects on gastric ulceration (Berger 2002, Loftin 2012, Sykes 2013). It is likely that a combination of the active ingredients will be most efficacious, with benefits noted when the supplement is added to the feed ration to help neutralise acid and form a gel-like protective coating on the stomach surface.

The daily administration of a targeted gastric supplement can be an important part of daily nutrition of the horse in training, alongside the use of pharmaceuticals such as omeprazole or esomeprazole when required.

Sweat loss

Horses have one of the highest rates of sweat loss of any animal, with sweat being comprised of both water and electrolyte ions such as sodium, potassium, chloride, magnesium and calcium. Therefore, it is not surprising that horses in training are at risk of unwanted issues should sweat loss not be replaced.

It is also worth noting that transportation can also lead to excessive sweat loss, with studies showing sweat rates of 5 litres per hour of travel on a warm day (van den berg 1998).

If the electrolytes lost in sweat are not adequately replaced, a drop in performance can result, as well as clinical issues such as thumps, dehydration and colic.

Electrolytes play key roles in the contraction of muscle fibres and transmission of nerve impulses. Horses without adequate electrolyte levels are at risk of early onset fatigue that may result in reduced stamina. It is also worth noting that horses that train on furosemide will have higher levels of key electrolyte losses, so will require targeted support to help maintain performance levels (Pagan 2014).

There is also evidence to suggest that pre-loading of electrolytes may be beneficial (Waller 2022). For horses in daily work, the addition of electrolytes to the evening feed will not only replace losses but also help optimise levels for the following day’s travel or race. The benefit of providing electrolytes with feed is that it will minimise the risk of the electrolyte salts irritating the stomach lining, which can occur if given immediately after exercise on an empty stomach. Feeding electrolytes when the horse is relaxed back in the stable will also allow them to drink freely, with the added benefit that electrolytes will stimulate the thirst reflex when they are relaxed, ensuring they are adequately hydrated for the following day.

Products should be chosen on the basis of adequate key electrolyte provision as not all products will provide meaningful levels of all the key electrolyte ions.

Muscle soreness

The process of muscle breakdown and repair is a normal adaptive response to training. This process can lead to inflammation and soreness or stiffness after exercise. In humans, there is a well-recognised condition called Delayed Onset Muscle Soreness (DOMS).

Further research is required to fully understand the impact of DOMS in horses. DOMS is the muscular pain that develops 24–72 hours after a period of intense exercise. There is no pain felt by the muscles at the time of exercise, in contrast to a ‘torn muscle’ or ‘tying-up’ for example.

In humans, DOMS is thought to be the result of tiny microscopic fractures in muscle cells. This happens when doing an activity that the muscles are not used to doing or have done it in a more strenuous way than they are used to.

The muscles quickly adapt to being able to handle new activities, thus avoiding further damage in the future; this is known as the “repeated-bout effect”. When this happens, the micro-fractures will not typically develop unless the activity has changed in some substantial way. As a general rule, as long as the change to the exercise is under what is normally done, DOMS are not experienced as a result of the activity.

In practice, avoiding any post-exercise muscle soreness in a training programme may be unavoidable, as exercise intensity and duration increases. Horses are far from being machines, so there is a fine balance between a programme that gets a horse fit for purpose without some post-exercise muscle discomfort. Physiotherapy, swimming and turnout will all likely benefit horses experiencing muscle discomfort. Whilst non-steroidal anti-inflammatories will always have their place for horses in training, one area of advancement is the use of plant-based phytochemicals to support the anti-inflammatory response (Pekacar 2021). These may have the benefit of not leading to unwanted gastrointestinal side effects and not having prolonged withdrawal times, although this should always be checked with any supplement particularly with the recent update regarding MSM on the BHA prohibited substance list.

Exercise will also lead to a process of muscle cell damage caused by oxidative stress. This is an inflammatory process and recovery from oxidative stress is key to allow for muscle cell repair and growth. Antioxidants are compounds that help recovery and repair of muscle cells following periods of intense exercise. The process of oxidative stress in muscle cells can lead to muscle fatigue and inflammation if left unsupported. Antioxidant supplementation in the form of Vitamin E or plant-based compounds can help protect against excessive oxidative stress and support muscle repair after exercise (Siciliano 1997).

Conclusion

Nutritional management of horses in training is a complex topic, not least as every horse is an individual and so often needs feeding accordingly. Whilst there is a lot of science available on the subject, the ‘art of feeding’ a racehorse—something that trainers and their staff often have in-depth knowledge of— remains an incredibly important aspect. Targeted nutritional supplements undoubtedly have their place, as discussed in, but not limited to, the scenarios above. 

Veterinarians, physiotherapists, other paraprofessionals and nutritionists all play a role in minimising health issues and maximising performance. In the quest for optimal performance on the track, nutritional support is one of the cornerstones of the ‘marginal gains’ theory that has long been adopted in elite human athletes. There is no doubt that racehorses themselves are supreme athletes that live by the mantra of Train, Race, Recover, and Repeat.

Thermoregulation in horses

Article by Adam Jackson - MRCVS

Exertional heat illness (EHI) is a complex disease where thoroughbred racehorses are at significant risk due to the fact that their workload is intensive in combination with the high rate of heat production associated with its metabolism.  In order to understand how this disease manifests and to develop preventative measures and treatments, it is important to understand thermoregulation in horses. 

What is thermoregulation?

With continuous alteration in the surrounding temperature, thermoregulation allows the horse to maintain its body temperature within certain limits.  Thermoregulation is part of the greater process of homeostasis, which is a number of self-regulating processes the horse uses to maintain body stability in the face of changing external conditions.  Homeostasis and thermoregulation are vital for the horse to maintain its internal environment to ensure its health while disruption of these processes leads to diseases. 

The horse’s normal temperature range is 37.5–38.5°C (99–101°F).  Hyperthermia is the condition in which the body temperature increases above normal due to heat increasing faster than the body can reduce it. Hypothermia is the opposite condition, where the body temperature decreases below normal levels as the body is losing heat faster than producing it.   These conditions are due to the malfunction of thermoregulatory and homeostatic control mechanisms.

Horses are colloquially referred to as warm-blooded mammals—also known as endotherms because they maintain and regulate their core body, and this is opposite ectotherms such as reptiles.  The exercising horse converts stored chemical energy into mechanical energy when contracting various muscles in its body. However, this process is relatively inefficient because it loses roughly 80% of energy released from energy stores as heat. The horse must have effective ways to dissipate this generated heat; otherwise, the raised body temperatures may be life threatening.

Transfer of body heat

There are multiple ways heat may be transferred, and this will flow from one area to another by:

1. Evaporation 

The main way body heat is lost during warm temperatures is through the process of evaporation of water from the horse’s body surface. It is a combination of perspiration, sweating and panting that allows evaporation to occur.

Sweating is an inefficient process because the evaporation rate may exceed the body heat produced by the horse, resulting in the horse becoming covered and dripping sweat. This phenomenon occurs faster with humid weather (high pressure).

Insensible perspiration is the loss of water through the skin, which does not occur as perceivable sweat. Insensible perspiration takes place at an almost constant rate and is the evaporative loss from skin; but unlike sweating, the fluid loss is pure water with no solutes (salts) lost. The horse uses insensible perspiration to cool its body.

It is not common for horses to pant in order to dissipate heat; however, there is evidence that the respiratory tract of the horse can aid in evaporative heat loss through panting.

2. Conduction

Conduction is the process where heat is transferred from a hot object to a colder object, and in the case of the horse, this heat transfer is between its body and the air.  However, the air has poor thermal conductivity, meaning that conduction plays a small role in thermoregulation of the horse.   Conduction may help if the horse is lying in a cool area or is bathed in cool water.  

The horse has the greatest temperature changes occurring at its extremities, such as its distal limbs and head.  The horse can alter its blood flow by constricting or dilating its blood vessels in order to prevent heat loss or overheating, respectively. 

Interestingly, the horse will lie down and draw its limbs close to its body in order to reduce its surface area and to control conduction. There also have been some adaptive changes in other equids like mules and burros, where shorter limbs, longer ears and leaner bodies increase its surface area to help in heat loss tolerance.

3. Convection 

Convection is the rising motion of warmer areas of a liquid or gas and the sinking motion of cooler areas of the liquid or gas.  Convection is continuously taking place between the surface of the body and the surrounding air. Free convection at the skin surface causes heat loss if the temperature is low with additional forced convective heat transfer with wind blowing across the body surface.

When faced with cold weather, a thick hair coat insulates and resists heat transfer because it traps air close to the skin; thus, preventing heat loss. Whereas, the horse has a fine hair coat in the summer to help in heat loss.

4. Radiation

Radiation is the movement of heat between objects without direct physical contact.  Solar radiation is received from the sun and can be significant in hot environments, especially if the horse is exposed for long periods of time.  A horse standing in bright sunlight can absorb a large amount of solar radiation that can exceed its metabolic heat production, which may cause heat stress. 

How the horse regulates its body temperature

The horse must regulate its heat production and heat loss using thermoregulatory mechanisms.  There are many peripheral thermoreceptors that detect changes in temperature, which leads to the production of proportional nerve impulses. These thermoregulators are located in the skin skeletal muscles, the abdomen, the spinal cord and the midbrain with the hypothalamus being instrumental in regulating the internal temperature of the horse.   A coordinating centre in the central nervous system receives these nerve incoming impulses and produces output signals to organs that will alter the body temperature by acting to reduce heat loss or eliminate accumulated heat.  

The racehorse and thermoregulation

The main source of body heat accumulation in the racehorse is associated with muscular contraction.  At the initiation of exercise, the racehorse’s metabolic heat production, arising from muscle contraction, increases abruptly.  The heat production does alter the level of intensity of the work as well as the type of exercise undertaken.  

During exercise, the core body temperature increases because heat is generated and the horse’s blood system distributes this heat throughout the body. Hodgson and colleagues have theorised and confirmed via treadmill studies that the racehorse has the highest rate of heat production compared to other sporting horses. In fact, the racehorse’s body temperature can rise 0.8°C per minute, reaching 42.0°C. But what core temperature can the horse tolerate and not succumb to heat illness and mortality?  The critical temperature for EHI (exertional heat illness) is not known, but studies have demonstrated that a racehorse can be found to have core temperatures between 42–43°C without any clinical symptoms. Currently, anecdotal evidence is only available, suggesting that a core temperature of 43.5°C will result in manifestation of EHI with the horse demonstrating central nervous system dysfunction such as ataxia (incoordination).  In addition, temperatures greater than 44°C result in collapse. 

Heat loss in horses

A horse loses heat to the environment by a combination of convection, evaporation and radiation, which is magnified during racing due to airflow across the body. However, if body heat gained through racing is not minimised by convection, then the racehorse’s body temperature is regulated entirely by evaporation of sweat. This evaporation takes place on the horse’s skin surface and respiratory tract.  

The horse has highly effective sweat glands found in both haired and hairless skin, which produces sweat rates that are highest in the animal kingdom.   Efficient evaporative cooling is present in the horse because its sweat has a protein called latherin, which acts as a wetting agent (surfactant); this allows the sweat to move from its skin to the hair.

Because of the horse’s highly blood-rich mucosa of its upper respiratory tract, the horse has a very efficient and effective heat exchange system.  Estimates suggest this pathway dissipates 30% of generated heat by the horse during exercise.  As the horse exercises, there is blood vessel dilation, which increases blood flow to the mucosa that allows more heat to be dissipated to the environment. When the respiratory tract maximises evaporative heat loss, the horse begins to pant. Panting is a respiratory rate greater than 120 breaths per minute with the presence of dilated nostrils; and the horse adopts a rocking motion. However, if humidity is high, the ability to evaporate heat via the respiratory route and skin surface is impaired. The respiratory evaporative heat loss allows the cooling of venous blood that drains from the face and scalp. This blood may be up to 3.0°C cooler than the core body temperature of 42.0°C. And as it enters the central circulatory system, it can significantly have a whole-body cooling effect. This system is likely an underestimated and significant means to cool the horse.

Pathophysiology of EHI  in the thoroughbred

Although it is inconsistent to determine what temperature may lead to exertional heat illness (EHI), it is known that strenuous exercise, especially during heat stress conditions leads to this disease.  In human medicine, this disease is recognised when nervous system dysfunction becomes apparent.  There are two suggested pathways that lead to EHI, which may work independently or in combination depending on the environmental factors that are present during racing/training.

1. Heat toxicity pathway

Heat is known to detrimentally affect cells by denaturing proteins leading to irreversible damage.  In general, heat causes damage to cells of the vascular system leading to widespread intravascular coagulation (blood clot formation), pathologically observed as micro thrombi (miniature blood clots) deposits in the kidneys, heart, lungs and liver.  Ultimately, this leads to damaged organs and their failure.

Heat tissue damage depends on the degree of heat as well as the exposure time to this heat. Mammalian tissue has a level of thermal damage at 240 minutes at 42°C, 60 minutes at 43°C, 30 minutes at 44°C or 15 minutes at 45°C.  This heat damage must be borne in mind following a race requiring suitable and appropriate cooling methods, otherwise inadequate cooling may lead to extended periods of thermal damage causing disease. 

The traditional viewpoint is that EHI is caused by strenuous exercise in extreme heat and/or humidity.  However, recent studies have revealed that environmental conditions may only cause 43% of EHI cases, thus, suggesting that other factors are involved.

2. Heat sepsis pathway

In some instances. a horse suffering from EHI may present with symptoms and clinical signs similar to sepsis like that seen in an acute bacterial infection. 

A bacterial infection leading to sepsis causes an extreme body response and a life threatening medical emergency.  Sepsis triggers a chain reaction throughout the body particularly affecting the lungs, urinary tract, skin and gastrointestinal tract.

Strenuous exercise in combination with adverse environmental conditions may lead to sepsis without the presence of a bacterial infection— also known as an endotoxemic pathway—causing poor oxygen supply to the mucosal gastrointestinal barrier. Ultimately, the integrity of the gastrointestinal tract is compromised, allowing endotoxins to enter the blood system and resulting in exercise-induced gastrointestinal syndrome (EIGS).

However, researchers have observed that EHI in racehorses is unpredictable as EHI may develop in horses following exercise despite “safe” environmental conditions.  Even with adequate cooling and resuscitative therapies, tissue damage that occurs demonstrates that thermoregulatory and inflammatory pathways may vary, and hyperthermia may be the trigger but may not necessarily be driving the condition.

Diagnosis of EHI

The diagnosis of EHI is based on the malfunctioning of the central nervous system.

Initially, hyperthermia reduces the blood flow to the cerebrum of the brain, leading to a decrease of oxygen to that area—also known as ischemia. As a result, the clinical signs are:

• Extreme restlessness

• Confusion

• Substantial headache

If this hyperthermia continues, then the blood-brain barrier (an immunological barrier between circulating blood that may contain microorganisms like bacteria and viruses to the central nervous system) begins to leak plasma proteins, resulting in cerebral oedema (build up of fluid causing affected organ to become swollen). If treatment is not initiated at this point, then neuronal injury will result especially in the cerebellum.

EHI follows and involves serious CNS dysfunction.  The clinical signs associated with EHI are:

• Delirium

• Horses unaware of their surroundings

The final stage of EHI occurs when the swollen oedematous brain compresses vital tissue causing cellular damage. The clinical signs of end-stage EHI are:

• Collapse

• Unconsciousness

• Coma

• Death

Definition of EHI

EHI most commonly occurs immediately after a race when the horse is panting, sweating profusely and may be dripping with sweat. The most reliable indication of EHI is clinical signs associated with the dysfunction of the central nervous system in the presence of hyperthermia. Researchers have provided descriptions of levels of CNS dysfunction, ranging from level 1 to level 4.

Level 1 – The earliest recognizable signs of CNS dysfunction

The horse becomes restless, agitated and irritable. There is often head nodding or head shaking. The horse is difficult to restrain and will not stand still.  Therapeutic intervention such as cooling can resolve these clinical signs, but if the horse is inadequately cooled then the disease can escalate. 

Level 2 – Obvious neurological dysfunction

Often misdiagnosed as colic symptoms, the horse becomes further agitated and irritable with the horse kicking out without any particular stimulus present. This stage is dangerous to all handlers involved as the horse’s behaviour is unpredictable. 

Level 3 – Bizarre neurological signs

At this stage, the horse has an altered mentation appearing vacant, glassy-eyed and “spaced-out”.  In addition, there is extreme disorientation with a head tilt and leaning to one side with varying levels of ataxia (wobbly).  It has been observed that horses may walk forward, stop, rear and throw themselves backwards.  It is a very dangerous stage, as horses are known to run at fences, obstacles and people. Horses may also present as having a hind limb lameness appearing as a fractured leg with hopping on the good limb.  These clinical signs may resolve with treatment intervention.

Level 4 – Severe CNS dysfunction

There is severe CNS dysfunction at this stage of EHI with extreme ataxia, disorientation and lack of unawareness of its surroundings. The horse will continuously stagger and repeatedly fall down and get up while possibly colliding with people or objects with a plunging action. Unsurprising, the horse is at risk of severe and significant injury.  Eventual collapse with the loss of consciousness and even death may arise.

Treatment of EHI

In order to achieve success in the treatment of EHI, it is imperative that there is early detection, rapid assessment and aggressive cooling. The shorter the period is between recognising the condition and treatment, the greater the chance of a successful outcome.  In particular settings such as racecourses or on particularly hot and humid days, events must be properly equipped with easily accessible veterinary care and cooling devices. It is highly effective if a trained worker inspects every horse in order to identify those horses at risk or exhibiting symptoms. 

If EHI is recognised, veterinary intervention will be paramount in the recovery to prevent further illness and suppress symptoms. It will be important to note any withdrawal periods of any non-steroidal anti-inflammatories (NSAIDs) and analgesics before returning to racing. There are a number of effective ways to cool the horse with easily accessible resources.

Whole body cooling systems

Cooling the horse with ice-cold water is an effective way to draw heat from the underlying tissues. In addition, cooling the skin redistributes cooled blood back to the central circulatory system thus reducing thermal strain with the cooling of core body temperature.

The system that works best for horses due to its size is spray cooling heat transfer. It is ideal to have two operators to spray either side of the horse. It is recommended to begin at the head and neck followed by the chest and forelimbs then the body, hind limbs and between the legs. Spray nozzles are recommended to provide an even coverage of the skin surface.   

Dousing is another technique in which horses are placed in stalls and showered continuously until the condition resolves. Pouring buckets over the entire body of the horse is not recommended as most of the water falls to the ground, thus, not efficient at cooling the horse. 

Because most horses suffer from EHI immediately after the race, the appropriate location for inspection, cooling systems and veterinary care should be in the dismounting yard and tie-up stalls.  There must be an adequate supply of ice to ensure ice-cold water treatment. 

When treating a horse with EHI, there must be continuous and uninterrupted cooling until the CNS dysfunction has disappeared. 
When the skin surface temperature decreases to 30°C, cutaneous skin vessels begin to disappear; CNS function returns to normal, and there is the normalisation of behaviour. Cooling can be stopped, and the horse can be walked once CNS abnormalities have resolved. It must remain closely monitored for a further 30 minutes in a well-ventilated and shaded region. It is important that they are not unattended.

Scraping sweat off of the horse must only be done if the conditions are humid with no airflow.  However, if it is hot and there is good airflow, scraping is unnecessary because the sweat will evaporate.

Cooling collars

During strenuous exercise, there is a combination of heat production in the brain, reduced cerebral blood flow, creating cerebral ischaemia as well as the brain being perfused with hot blood. It is believed that cooling the carotid artery that aids in blood perfusion of the brain might be a strategy to cool the brain. A large collar is placed on either side and around the full length of the horse’s neck and is cooled by crushed ice providing a heat sink around the carotid artery; and it is able to pump cooled blood into the brain. 

Another possible benefit of this device is the cooling of the jugular veins, which lie adjacent to the carotid arteries.  The cooled blood in the jugular veins enter the heart and is pumped to the rest of the body, hence, potentially cooling the whole body. In addition, it is thought that the cooling of the carotid artery causes it to dilate, allowing greater blood flow into the brain. 

Provision of shaded areas

Shaded areas with surfaces that reflect heat, dry fans providing air flow and strategically placed hoses to provide cool water is an important welfare initiative at racecourses in order to minimise risk of EHI and treat when necessary. 

Conclusion

The most effective treatment of EHI is the early detection of the disease as well as post-race infrastructure that allows monitoring of horses in cooling conditions, while providing easily accessible treatment modalities when they are needed.  

Evaluating the horse’s central nervous system dysfunction is essential to recognise both the disease as well as monitoring the progression of the disease. CNS dysfunction allows one to define the severity of the condition. 

Understanding the pathophysiology of EHI is essential. It is important to recognise that it is a complex condition where both the inflammatory and thermoregulatory pathways work in combination. With a better understanding of these pathways, more effective treatment for this disease may be found.

A new mission for Criquette Head

Article by Katherine Ford

Five years after retiring as a trainer, the handler most famous for the Arc double of Trêve wintered in the Bahamas where she devoted herself to caring for her mother Ghislaine during her final months. A figure in French and international racing and bloodstock alongside her late husband Alec, Ghislaine Head was influential in the running of the Haras du Quesnay. Her colours were carried notably by Arc heroine Three Troikas and homebred Prix du Jockey-Club winner Bering; and she passed away peacefully at age 95 in early June.

Horses were far away in the flesh during this time in the Bahamas but still close to Criquette’s heart and very present in her mind. “When would be a convenient time for a chat?” I texted Criquette Head to arrange this interview. The reply pings back, “You can call me at 11.30am French time; I get up at 5am (EST) here every day for my first lot.”

So it is 5.30am in the Bahamas, and Criquette is in fine form as ever with plenty of ideas to discuss. “I’m always wide awake at this time. I can’t get it out of my system. Of course there are no horses here, just water and boats.” When Criquette retired, she announced a plan to sail across the Atlantic in her yacht, named Trêve. However, in typical altruistic style of the former president of the European Trainers Federation, the adventure has been on hold. “My boat is here, but I haven’t done the crossing yet. I will do it one day, but for the moment, my priority is taking care of my mother. I will stay at her side as long as she needs me.” 

While she had no physical contact with horses in the Bahamas, and no imminent trans-Altantic sail to prepare for, Criquette has been devoting time and energy recently to the association CIFCH (Conseil Indépendant pour la Filière des Courses Hippiques, or Independent Council for the Racing Industry), which she created with long-time friend and associate Martine Della Rocca Fasquelle some three years ago and now presides. 

Senator Anne-Catherine Loisier & Martine Della Rocca Fasquelle.

“The idea came about because I found that our politicians didn’t understand the racing world. I said to myself that as I have some spare time, I would create a little association, and I would try to ask our politicians, those who vote for our laws in the National Assembly or the Senate, to understand what racing means. We are completely separate from any official organisation, and we don’t interfere with France Galop or Le Trot (French harness racing authority). I just want to show the decision makers what racing is all about. I have met a lot of people and invited them to the races. That’s all… I try to make them realise the importance of the racing industry, and the reactions have been very positive.”

An eclectic membership 

The CIFCH counts 140 parliamentarians among its membership and supporters, which is a varied panel composed of racing and non-racing people, from a wide professional spectrum. 

As Martine Della Rocca Fasquelle explains, “Our aim is to share ideas and knowledge, and everyone contributes what they can, depending upon their area of expertise.” Criquette adds, “We wanted to surround ourselves with competent people who are all volunteers. They all like horses, not necessarily racehorses but the horse in general, and the association works in favour of the entire equine sector. The VAT issue is an important one for the CIFCH. If we manage to reduce the rate for equine activity to 10%, the entire horse industry will reap the benefit.”

A key supporter is Senator Anne-Catherine Loisier, vice-president of the CIFCH and who notably assisted in opening the doors of the National Assembly for a meeting with French mayors. Criquette continues, “A year ago, we wrote to all the mayors in France with a racecourse in their municipality with a questionnaire, and most of them very kindly replied to us. However, it’s a shame that the mayors with some of our most important racecourses didn’t respond. We asked them about the economic importance of the racecourses for their municipality; and then we organised a meeting at the National Assembly, which was very productive.” Martine Della Rocca Fasquelle adds, “This was the first time that mayors have been heard singing the praises of racing. We were surprised as we received reactions from very high up, including Emmanuel Macron, who congratulated us for the results of the racing industry.”

Spreading the word

Senators Sonia de la Prôvoté and Valérie Letard and spouses with Criquette Head, Prix de l'Arc de Triomphe 2021.

The CIFCH compiled the responses from 27 mayors, representing communes ranging from Chantilly and Cagnes-Sur-Mer, several municipalities in the West of France (which is a hive of activity for both trotting and gallop racing, training and breeding), to the homes of tracks organising just one or two meetings per year, into an album “Une Ville, Un Hippodrome: les maires ont la parole.” (towns and racecourses, in the words of their mayors). The brochure, which has been distributed to members and interested parties, is an advocacy of the benefits of racing to local communities. 

Naturally, Isabelle Wojtoviez, mayoress of Chantilly, underlines the significance of the racecourse and training centre for the town, “It is impossible to imagine Chantilly without horses. The animal is at the centre of our economy, a pillar of our history and a vital tourist attraction...” 

Bertrand de Guébriant, mayor of 5,000-inhabitant Craon in the West of France, where the racecourse hosts 10 meetings for a mixture of jumps, flat and trotting action, says, “Craon is one of the most popular provincial tracks in France, and we welcome 25,000 people for our ‘Trois Glorieuses’ festival each year, making it a major tourist attraction. The notoriety of our racing means that the town has a riding centre and a nearby training centre for employment with horses, whose most famous graduate is certainly (leading jump jockey) Clément Lefebvre. During racing periods, Craon enjoys visibility in the media, and finally, the community receives a share of pari-mutuel turnover, which is a real plus for our budget.”

With 80 meetings per year in the three disciplines, the racecourse at Cagnes-sur-Mer plays an important role in the town’s economy. And with its Côte d’Azur coastline, charming old town and proximity to Nice, it already has plenty of advantages.

Mayor Louis Nègre explains, “The image of Cagnes-sur-Mer is intimately linked to the racecourse, especially on an international level. The opportunity for visitors to enjoy racing in a spectacular environment overlooking the Mediterranean represents a unique experience, which contributes to tourists returning to the town. The economic activity connected to the racecourse and training centre is important year-round, while hotels, restaurants and the property markets benefit notably from racing during otherwise quiet periods of the season (during the winter flat and jumps meetings).”

Senator Anne-Catherine Loisier, vice-president of the CIFCH with Criquette Head and Deputy Géraldine Bannier, vice-president of the CIFCH.

The virtuous pari-mutuel model

For Criquette and her fellow CIFCH members and supporters, it is vital to spread positive messages such as these in order to preserve the favourable French system. “Racing has a colossal impact on the economic and environmental state of our country, and this is thanks to our PMU system which must be protected at all costs; however, I get the impression that it is being destroyed. When I see that (online betting operator) Ze Turf has been bought by (lottery and sports betting operator) La Française des Jeux, I fear that racing punters may be tempted away to bet on poker or other markets. We need the PMU and its financial input, which represents our livelihood and that of our regions, our studs and stables. My aim is to valorise and protect this ecosystem which is an example across Europe. France has by far the highest prize money in Europe, and that needs to be preserved. Our system also brings money in for the state; it’s a win-win system. Indeed during the Covid pandemic, the PMU registered good results because the football and all other activity was stopped. We were lucky that the state understood the need for racing and breeding activity to continue. This is a good demonstration of the importance for government to understand the depth of the racing activity and that it is not just a sport like football, for example.”

Racing across Europe and further afield is faced with issues of perception, either from the general public or government representatives. “An association like the CIFCH would have a role to play in other countries,” says Criquette, “but things are more complicated in nations with bookmakers. If you look at the rising powers in world racing nowadays, such as Hong Kong and Japan, they have adopted the pari-mutuel model. I think that the World Pool is a very good concept, which can contribute to promoting the tote system and help racing to raise its level on a global scale.”

“The CIFCH doesn’t get involved in specific debates such as the whip. Personally, I am in favour of limiting the number of strokes, but we must be careful not to overreact. Those who are against racing are people who have never been close to a horse at the races or in training; and one of the missions of the CIFCH is to demonstrate that horse welfare is at the centre of our profession. We are pleased to show newcomers behind the scenes and the quality of care which racehorses receive.”

Opening doors for future owners

After a series of visits, debates and conferences with decision-makers, the CIFCH is set to widen its contacts further in 2023, when a major focus for the committee will be a two-day event in June in Normandy, aimed at business people and potential owners. 

Criquette explains, “We will invite entrepreneurs and business people who have nothing to do with racing to come and spend time at a stud farm and training centre in Normandy. Like a lot of people today, all they know about horses is that they have four legs, a head and a tail… Throughout my career I always welcomed people into my stable to discover the horses, and the reactions were invariably positive. Many of these [people] went on to become owners, not necessarily with me; and I was always pleased to see them develop their interest. I was brought up to be very open and welcoming, and now [that] I have free time, I want to continue to help people find out more about racing.”

Always renowned for her generosity with time and explanations, Criquette inherited these and many other qualities from her late father, the great breeder and trainer Alec Head who passed away last summer at age 97. 

Criquette and fellow CIFCH members at a meeting in Chantilly, 2021.

“He has left us with a fantastic legacy, and I owe him my success. He always loved his profession and defended the racing industry; and along with Roland de Chambure, he was a precursor in opening up the market with the USA. One thing which struck me when I was younger was that he used to say, ‘You should always try to read your horse. Once you have understood your horse, then the horse will tell you what they are capable of’. I used to say the same thing to all the young assistants who came to work with me and who are now trainers. I told them to pick just one horse and ignore the 80 others; study that one horse, and then tell me what they observed as the horse developed. For me, that is the basis of training. Like people, no two horses are the same, and so you cannot follow the same recipe with them all. You can lose horses by rushing them, and during my era, we were fortunate to have plenty of time. Last year, once again, the examples of Flightline and Baaeed proved that it can be beneficial to wait.”

The family dynasty continues

Criquette’s brother Freddy Head called time on his illustrious training career last year, and the family name is now represented in the profession by his son, Classic-winning Christopher and daughter Victoria. “Papa would have been very proud to see Victoria win her first race recently, and Christopher’s success. Christopher spent time working alongside his father, and two years with me, and Victoria worked for much better trainers than me! She was with Gai Waterhouse, Aidan O’Brien and André Fabre, as well as with her father. We have (French racing channel) Equidia in the Bahamas, so I’m often in front of my TV at 6am here! I keep an eye on everyone, not just my family…” 

In addition to owning horses or shares with a range of trainers in France and former assistant David Menuisier in the UK, Criquette also maintains her interest in breeding, despite the heart-wrenching sale of the family’s celebrated Haras du Quesnay last year. 

“There were a lot of us—five including my mother—and we didn’t all have the same ideas, so it was a family decision to sell. I love breeding, so I will continue with five broodmares. My grandson Fernando (Laffon-Parias) wants to be an agent and is interested in breeding, so this year I planned all the matings with him. I did consider buying a farm myself, but finally my mares will stay at the Quesnay as the new owners are taking in boarders and have kept on all the old staff under manager Vincent Rimaud. So, I decided to stay, and I will enjoy returning to the stud. It will be a very different feeling for me to visit, with no pressure or concerns about managerial issues. I will just be able to go and admire my mares and foals!”

As ever, with Criquette, the love of horses shines through in her words. “We talk endlessly about the people involved with the horses, which is logical in a way, but in the end, everything depends upon the animal. At all levels, whether in breeding, training or racing, the horse always has the last word.” If Criquette has her way, this would also be true for politics! 

What does it take to become a trainer?

Article by Lissa Oliver

While each year we seem to lose many established trainers, often due to financial reasons, the training ranks continue to welcome fresh new faces—many of them particularly young. Those already struggling to make a living might question why, yet a certain amount of optimism is a prerequisite for embarking on any career within the thoroughbred industry.

Are the licencing bodies doing enough to equip new trainers for the reality of the career ahead? Is that even a question we should be asking, given that in most other industries an entrepreneur is free to start up a business as they please? What do our governing bodies consider to be the basic requirements necessary to apply for a trainer’s licence?

Deutscher Galopp manages to encapsulate exactly what is needed to consider applying for a trainer’s licence, pointing out the need for an excellent knowledge of racehorses and the world of horseracing; a capacity for management and personnel management; a mastery of professional relations, particularly with owners; a capacity for analysis in order to develop the performance of his or her horses; a technical and strategic sense; and a great geographical mobility. 

Indeed, few Germany-based trainers would argue with the latter—smaller yards frequently needing to chase prize money in France due to the dominance at home of the larger stables. Interestingly, the traits of coolness and self-confidence are also listed—food for thought, perhaps.

In Germany, the licensing process doesn’t appear to be as bureaucratic as in Britain, for example, with no minimum age or experience criteria or detail of finances required. Deutscher Galopp has bundled its diverse training offerings and further education programme in its own academy—The Deutscher Galopp Academy—which aims to offer and conduct seminars and further education and training in horse racing for all interested groups, even racegoers.

The prerequisite for working as a professional trainer in Germany is completion of the Horse Management Masters examination in the horse racing training section at the Academy. The aim of the course is to acquire the necessary knowledge to run a training company independently, to masterfully carry out the work that occurs there, and to properly educate and equip the trainees for the profession of racehorse trainer. “That course can last a year or more, and not everybody is automatically qualified; the government decides who will be able to take part,” explains Rüdiger Schmanns, director of racing.

France also places emphasis on a robust pre-training course, and candidates must have at least two years’ experience in a racing yard. The Ecole des Courses Hippiques (AFASEC) is the benchmark training organisation for all horse racing professions, with five campuses throughout France as close as possible to the largest training centres. New France Galop Rules in relation to applying for the French trainer’s licence are due to come into effect later this year and are therefore included here. 

The Trainer’s Course serves for both trotting and racing candidates, but the modules are specific to each specialty. The acquired knowledge is considered essential for starting out as a professional trainer in France. Of the maximum of 14 places, seven are reserved for racing applicants. The France Galop licensing department ultimately decides who qualifies for access to the 175-hour training, which takes place over a five-week period in May and June annually. The course fee is €2,275, and candidates must successfully complete a two-hour pre-selection examination on their horse racing knowledge at least six weeks prior to the course.

The bulk of the course is online, with 10 days (70 hours) of in-person classes, including two days of written and oral examinations. The six modules cover accounting and management; hygiene, horse health and equine welfare; social legislation; professional regulation; communication and business development; and human resources, management, awareness of labour law and preventive measures against moral and sexual harassment in the workplace. The candidate must obtain a mark of at least 10 out of 20 in each of these subjects.

Training Licence Requirements

The British Horseracing Authority (BHA) relies on a very stringent criteria for those who may apply for a training licence, which reflects the similar training provided by AFASEC. Applicants are required to demonstrate competence and capability to train; access to appropriate training facilities; security of tenure for the premises from which they wish to train; a minimum of three horses in training; compliance with relevant health and safety responsibilities; ability to provide full details of their employment status; compliance with all relevant employment responsibilities; ability to appropriate Public Liability Insurance and, where appropriate, Employers' Liability Insurance; necessary financial resources available; and that they are otherwise in all the circumstances suitable to hold a licence and are deemed ‘fit and proper’.

This means applicants must have a minimum of five years’ experience in a training establishment, including at least two years in a responsible and senior position—preferably as an assistant trainer in a successful racing yard. Alternatively, a track record as a permit holder with at least three wins with a reasonable spread of horses, or having run a Point-to-Point yard for at least two years and having trained a minimum of 10 Point-to-Point/Hunter Chase wins with a reasonable spread of horses.

Applicants must have attained the Level 3 Diploma in Work Based Racecourse Care and Management (WBD) and successfully completed Modules 1, 2 and 3 of the training programme held at the British Racing School or the Northern Racing College. They must also attend a one-day training seminar for potential trainers at Weatherbys’ offices.

Furthermore, the yard and facilities must pass inspection. If the applicant is to train horses for the Flat, he or she will be expected to have access to gallops of six furlongs, including four furlongs straight, within hacking distance of the stables and facilities for schooling horses through starting stalls. National Hunt trainers must have access to gallops of six furlongs within hacking distance of the stables, at least one plain fence and one open ditch with wings, over which two horses are able to school alongside one another, and at least two flights of hurdles with wings, over which two horses can school alongside, as well as access to ‘nursery facilities’, such as poles.

The BHA takes into account the financial track record of the applicant and assesses the likely financial soundness of the proposed training business. A recognised financial reference must show the applicant to have available working capital or overdraft facilities of at least £40,000. A projected profit and loss account and a cash flow projection of the training business for the first 12 months must be provided.

To become a trainer in Ireland, applicants must be at least 21 years of age with a minimum of two years’ experience working in a racing yard. Alternatively, the holder of a rider’s licence with an acceptable number of rides for the same period, or a registered Point-to-Point handler with an acceptable number of runners, may also be eligible to apply. 

Applicants to the Irish Horseracing Regulatory Board (IHRB) Head of Licensing are required to successfully complete an assessment to establish prior knowledge of the industry in order to qualify for the Pre-Trainer’s Course. The assessment consists of practical, oral, and written elements. The Pre-Trainer’s Course is held twice a year, in spring and autumn, over a three-week period and delivered via a blended approach of sessions online and in-person. 

Following successful completion, a stable inspection is then carried out by the IHRB on the proposed training establishment. The stable inspection report and application, together with all relevant documentation, is assessed by the Licensing Committee, who then arranges an interview with the candidate. The Licensing Committee ultimately decides  whether a licence is granted. The successful completion of the assessments and Pre-Trainers’ Course does not guarantee the issuing of a licence.

If we look at the smaller racing nations, the reliance on courses for trainers remains much the same. In the Czech Republic, for example, an applicant has to successfully graduate from the specialised course for trainers organised by the Czech Jockey Club. He or she must also have graduated at an apprentice training centre for horse breeding, horse racing or equestrian sport; have a school-leaving certificate from secondary school and at least 10 years’ experience in a racing yard; graduated from agricultural university or veterinary university and have at least two years’ experience in a racing yard; or graduated from another type of university and have at least five years’ experience. The Trainer’s Course is organised by the Czech Jockey Club every few years when enough requests from interested people warrant it. Karin Luftmanová tells us that it is also quite common to attend a course in Slovakia, and vice versa.

Interestingly, in Portugal, where the LPTG Professional License Commission is the only entity for issuing a trainer’s licence, applicants must be over 25 years of age and express a wish to try to make the training of racehorses “a permanent and paid activity”. They begin with an obligatory internship, to be completed successfully, with a minimum duration of six months with a foreign trainer, or 12 months with a national trainer. The League's Professional License Commission is made up of four members of the Board, designated by the racing director of the Technical Commission (CT), who has the ultimate say in granting the licence.

The work and knowledge involved in gaining a trainer’s licence is worth noting. In the general sphere of horse racing, the skills and qualifications of a trainer are not widely known or publicised. The public still tends to think in terms of retiring trainers simply handing over the reins to someone with experience, without considering exactly what that experience entails. 

In contrast, media coverage of jockey schools and stable staff apprenticeships are a staple, with those same opportunities commonly going out to schools to encourage school-leavers to embark on a racing career. In the wider world, we think nothing of having to go through various levels of higher education, and the Trainers’ Courses available throughout Europe could be viewed as akin to postgraduate degrees. Should our governing bodies be presenting the professional trainer’s pathway to schools and universities?

Certainly, as the racing world focuses on social licence and presenting itself in a fit way to a growing urban public, no longer in touch with agricultural roots and working animals, more should be made of the strict requirements to train. More to the point, trainers deserve fitting credit for their accomplishment in receiving and retaining their trainer’s licence. It is, indeed, a postgraduate degree to be proud of.

7 Simple Rules for Parasite Control in Racing Yards

Article by James Gibbons

When Benjamin Franklin wrote, in 1789, ‘in this world nothing can be said to be certain, except death and taxes’, he could, perhaps, have added another certainty to his list – worms in horses. Unlike most other infectious diseases of horses, such as strangles or influenza—which infect a small number of horses relative to the entire horse population at any one time—worms are present in almost all horses all of the time.  This fact leads to two obvious conclusions: first, it is not possible to eradicate parasites and the threat of parasitic disease from our horses; second, worm control is vital in any environment where horses are kept.  

The threat posed by intestinal worms to racehorse performance has long been recognised by horsemen the world over. For many years, regular treatment with anthelmintic drugs (‘dewormers’) was the mainstay of worm control in racing yards, as it was in most in areas of horse breeding and production. The emergence of resistance to these deworming drugs (referred to as ‘anthelmintic resistance’), in the last 10 years in particular, has meant that such regular treatments may no longer be effective and may in fact make the resistance situation in the yard or farm worse. With this in mind, it is important that we consider how best to control worms while preserving the efficacy of the few deworming drugs available to us. This can be achieved using control programs comprised of drug- and non-drug control measures. This article sets out seven points/rules to consider and implement when developing such a worm control programme for racing yards. 

1. Know your enemy

It is not possible to draw up a parasite control program without considering which worms it is you are trying to control. The three main types of worms we are concerned with are strongyles (large and small redworms), ascarids (roundworms) and tapeworms. The role of tapeworms in equine intestinal disease is debated, but they appear to be linked to certain forms of colic when present in high numbers. Notably, there is no evidence of age-related immunity to tapeworms. Ascarids are a cause of disease in foals primarily and yearlings and so are likely to be of less concern in most racing yards. However, unlike redworms, which are transmitted almost exclusively at grass, ascarids can be transmitted in the stable; and ascarid eggs survive for years in the environment so that a single infected animal can infect other young horses for years to come.  

Redworms are the most important parasite of horses and are found in horses of all ages where they can cause anaemia, weight loss, ill-thrift and diarrhoea. Large redworms can burrow into the walls of blood vessels that supply blood to the gut causing a very severe form of colic.  Small red worms can lie dormant in the gut wall for extended periods then emerge en masse to cause an acute shock-like syndrome with severe diarrhoea, which is often fatal.  

Faecal egg count (FEC) testing will identify if redworms or ascarid eggs are present in your horse’s droppings and this, in turn, tells you that the adult worm of that species is present in your horse’s gut. Tapeworm eggs can be detected by FEC testing, but it is not the most reliable method for their detection as the shedding of these eggs is not consistent. As redworms are the most relevant worm present in most yards, most of the information in this article relates specifically to the control of redworms rather than ascarids or tapeworms.

2. Know your horses’ risk

All trainers pride themselves on their knowledge of almost every aspect of their horses’ anatomy and physiology, but not all could tell you which of their horses are at greater or lesser risk of worms. As mentioned above, all horses are likely to carry some worms, but the adult worm burden and the number of worm eggs shed in faeces is far greater in younger horses than in mature stock.  Most horses between the ages of 5 and 15 years will have a lower worm burden, and a lower risk of parasitic disease, than horses below this age due to a degree of age-related immunity. Foals and yearlings can carry particularly high worm burdens and shed large numbers of eggs into the environment to infect other horses. 

It follows that any yard with yearlings—two- or three-year-olds—will need a comprehensive worm control programme; while yards with older stock may get away with less strenuous controls. Horses over the age of 15 may also have higher worm burdens. And while these are unlikely to be in training, they may be used as a riding horse or companion animal and act as a potential source of infection for the string.

3. Know your yard’s weak points

It is not unusual for our lab to get a call from a racehorse trainer wishing to express their disbelief that the faecal egg count test from their horses has tested positive for redworm eggs despite their horses having no access to grass. In these situations, careful questioning as to how the yard operates will usually reveal the use of turn-out paddocks for a short period at some point during the week. Invariably, these are shared, often quite small, paddocks which host many horses over time; and so they are more likely to be contaminated with worm eggs.  

While the intention is for the horse to get ‘a pick of grass’, it may be that it is more ‘a pick of worms’ they are getting in such paddocks! As part of a worm control plan, it is important to first identify high-traffic areas, which may be a pinch-point for worm transmission.  Once identified, the key to reducing the worm burden on such paddocks is ideally through the removal of droppings. This can be a labour-intensive exercise, but it only needs to be done twice weekly rather than daily. And there are now more automated methods for cleaning paddocks than the more traditional wheelbarrow and spade!  

4. Identify high shedders 

FEC testing not only tells you what type of worm is present in your horse’s droppings but also how many eggs there are per gramme of faeces.  Repeated FEC testing allows you to build up a picture of the shedding patterns of the horses within your stable. Horses in racing yards should have FEC testing carried out every three months. It is generally accepted that the shedding of worm eggs in horses follows the 80/20 rule; that is, 20% of the horses shed 80% of the eggs.  

If these high shedders in the group can be identified, then targeted treatment of them may be more beneficial (and cost-effective) than blanket treatment of the entire group.    Horses with a strongyle egg count in excess of 250 eggs per gramme (EPG) on repeated testing may be considered high shedders and require more frequent egg counts and treatment.  It is important to state that this figure of 250EPG is not absolute, and the threshold above which animals are considered high shedders or requiring treatment should be set in conjunction with your vet. Worm eggs are not distributed evenly within the droppings, so when collecting samples for FEC testing, make sure to take at least three faecal balls—each from a different area of the pile. 

FEC testing can only detect egg-laying adult worms, but the egg count is not a reliable indicator of the adult worm burden of the horse, i.e. a horse with a high FEC does not necessarily have a greater worm burden than a horse with a lower FEC; but the horse with the high FEC is more significant in terms of worm transmission to other horses. Immature worms that may be present in the horse are not detected by FEC testing. In recent years, new tests have been developed that can detect antibodies to tapeworms and small redworm in blood and/or saliva. These tests are a useful addition to any worm control programme. Regardless of the type of test used, dewormers are still necessary as part of any worm control programme, in foals and yearlings in particular, but also in high-risk environments, and in order to control the disease risks posed to horses of all ages by large strongyles.  

5. Know which drugs work

While it might seem like there is an endless range of deworming products for horses on the market, the number of active ingredients in these products is very limited with only four drugs (fenbendazole, ivermectin, moxidectin and pyrantel) available for the treatment of redworms and ascarids. With such limited availability, and no prospect of new worm treatments entering the market anytime soon, it is vital that we use the existing drugs judiciously so as to preserve their effectiveness into the future.  

The threat posed by anthelmintic resistance is very real. Already fenbendazole resistance in redworms is widespread, and ivermectin/moxidectin resistance in ascarids is becoming more common. This means that there are only one or two effective treatments remaining for these resistant worms. While thoughts of anthelmintic resistance may not keep any racehorse trainer awake at night, we do expect that the deworming treatments we use to be effective, not least because they cost quite a lot of money!  The only way to determine if our treatments are indeed effective is to carry out a faecal egg count reduction test (FECRT). 

This test follows on from the FEC test; any horse with a FEC of 500EPG or more should be treated with a dewormer and have a follow-up FEC carried out 10–14 days after that treatment. The percentage reduction in egg numbers is calculated and should be greater than 90–95% (depending on the drug). Reductions less than this are suggestive of a resistance problem. Because of the existing resistance situation, FECRTs should be carried out before using fenbendazole to treat redworms or ivermectin/moxidectin to treat ascarids. Equally, if you have any suspicion that a deworming product is not working effectively in your yard, then a FECRT for that drug should be carried out to investigate this.   

6. Don’t overtreat

Aside from the risk of anthelmintic resistance development and the significant costs incurred by frequent or blanket deworming of all horses in the yard, such treatments can have other effects on the horse, which may ultimately impact performance. Research has shown that anthelmintic administration is associated with a decrease in the diversity and abundance of certain bacteria in the horse’s gut, which may impact digestion and other metabolic processes. 

In humans, changes in the composition of the gut bacterial population have been shown to impact physiology, immunity and behaviour; and, while the structure of the gut may differ greatly between human and horses, there is no reason to believe the equine gut bacteria do not play a similarly important role in horse health. In recent years, the role of parasites in human health has been revaluated. And while they are still recognised as an important cause of disease, it is also accepted that they can play a beneficial role in the development of immunity and the prevention of some diseases. While we don’t have similar evidence of a benefit to horse health from parasites, it is not impossible that such benefits do really exist.  

A study of standardbred trotters in Denmark in 2011 found that horses with higher egg counts had better race finishing position than those with lower egg counts. So,  the presence of parasites does not always lead to poor performance! It was standard practice, in some racing yards, to deworm horses every eight weeks, but this seems excessive when one considers the biology of the worms involved. The small redworms take approximately eight weeks to develop to maturity in the horse, while the large redworms take approximately six months to do so. Treatment every eight weeks could only be justified if there were evidence of overwhelming worm exposure on an ongoing basis—something which is unlikely in a modern racing yard. Even if that were the case, other non-pharmaceutical controls would be necessary to get the situation under control.

7. Manage new arrivals

One of the challenges of worm control in a racing yard is the constant turnover of horses with some leaving the yard for rest or recovery from injury, others returning from such breaks and new horses joining the yard. When a horse leaves the yard, they leave the worm control programme as well. Evem if the yard’s deworming programme is followed while they are away, the risk factors in their new environment may be totally different and require an entirely different approach to treatment. More worrisome, the arrival of new horses or the return of others also risks the introduction of new or resistant parasites to the yard. In order to minimise this risk, all new arrivals should be isolated, tested and treated. Ideally, all new arrivals would be isolated for two weeks while a FECRT is carried out to ensure treatment has been effective.  

This may not be practical in all yards, but an isolation of period of at least three days after deworming should be observed to ensure all worms are shed before the horse joins the group. Treatment without isolation is not recommended as treated horses can shed viable eggs for a few days after deworming. There may be a temptation to let horses out to turnout paddocks for exercise or grass during the isolation period, but we have seen cases where this has led to the introduction of new parasites to the yard despite the horse being treated before it was turned out.   

There was a time when parasite control in racing yards was relatively simple and relied primarily on the regular use of deworming drugs. As with many aspects of horse racing, what was once considered acceptable is no longer so. Effective parasite control is not as simple anymore, and an overall plan designed to meet the needs of the individual yard is required. That is not to say that any trainer should be daunted by the prospect of drawing up such a plan. The seven points discussed here provide a basis to work from and your vet and laboratory are well placed to assist in building on this.  

Equine Neck CT: Advancing diagnostic precision in racehorses

Article by Rachel Tucker MRCVS

Introduction

When considering neck disorders in the racehorse, we most commonly think of severe conditions such as acute neck trauma and cervical vertebral myelopathy (Wobbler Syndrome). These represent the most severe end of the scale of orthopaedic and neurologic injury to the neck; and a diagnosis, or at least prognosis, is usually clear. However, neck conditions encompass a far wider range of clinical presentations. 

Horse positioned in ct scanner

At the milder end of the scale, signs may be subtle and easily missed, whilst still being responsible for discomfort and reduced performance. The recent ability to perform a computed tomography (CT) scan of a horse’s neck represents a major advancement in our ability to diagnose neck conditions. Timely and accurate diagnosis allows efficient and targeted treatment, the ability to plan schedules and improvement in welfare through the provision of appropriate treatment and earlier return to function. 

In neurologic cases, an accurate diagnosis facilitates risk management for both the horse, their handlers and riders, while improving safety for all.  As conditions and injuries of the neck are being better characterised using CT, new medical and surgical treatment options are being developed, giving the potential for improved outcomes and fewer losses from the racing industry. 

This article summarises how CT is being increasingly used by vets to diagnose conditions of the neck and how it is revealing previously unknown information and providing exciting new treatment opportunities. 

Presentation

Conditions of the neck can cause a range of signs in the horse, which are wide-ranging in their presentation and variable in their severity. The manner in which these conditions present depends on which anatomical structures are affected. Issues affecting the bones, joints and/or soft tissues of the neck can all cause neck pain, which can manifest in a number of ways. Cases of neck pain can be severe, resulting in a horse with a rigid, fixed neck carriage, an unwillingness to walk and struggling to eat, perhaps due to a traumatic event. Neck fractures are thankfully uncommon but can be catastrophic. 

More moderate signs might be displayed as a stiff neck, with reduced range of movement and resentment of ridden work. There may be pain on palpation of the neck and changes in the neck musculature. Increasingly, we are seeing horses with far more subtle signs, which are ultimately revealed to be due to neck pain and neck pathology. Typically, these horses might have an acceptable range of motion of their neck under most circumstances, but they suffer pain or restriction in certain scenarios, resulting in poor performance. This may be seen as tension through the neck, resisting rein contact, a reluctance to extend the neck over fences, or they may struggle on landing. 
Riders might report a feeling of restriction or asymmetry in the mobility of the neck. In addition, these horses may be prone to forelimb tripping or show subtle forelimb lameness. 

Any condition, which causes injury or disease to the spinal cord or nerves within the neck, also causes a specific range of neurologic signs. Compression of the spinal cord is most commonly caused by malformations or fractures of the cervical vertebrae, or enlargement of the adjacent articular process (facet) joints. This results in classic ‘Wobbler’ symptoms, which can range from subtle weakness and gait abnormalities, through to horses that are profoundly weak, ataxic and uncoordinated. This makes them prone to tripping, falling, or they may even become recumbent. 

Peripheral nerve deficits are uncommon but become most relevant if they affect the nerves supplying the forelimbs, which can result in tripping, forelimb lameness, or local sensory deficits. This lameness might be evident only in certain circumstances, such as when ridden in a rein contact. This lameness is difficult to pinpoint as there will be no abnormality to find in the lame limb, indeed a negative response to nerve and joint blocks (diagnostic analgesia) will usually be part of the diagnostic process.

Horses can present with varying combinations and severities of neck pain, neurologic signs and peripheral nerve deficits, creating a wide range of manifestations of neck related disease. 

Diagnosis

A diagnosis of neck pain is based on careful static and dynamic clinical examination and may be supported by seeing a positive response to treatment. Neurologic deficits are noted during a specific neurologic assessment, which includes a series of provocation tests such as asking a horse to walk over obstacles, back up, turn circles and walk up and down a hill. Confirming neck pathology as the cause of signs can be difficult. Until recently, radiography has been the mainstay imaging modality. Radiographs are useful for assessment of the cervical vertebrae and continue to play an important role in diagnosis; however the complex 3-dimensional shape of these bones, the large size of the neck and an inability to take orthogonal (right-angled) x-ray views means that this 2-dimensional imaging modality has significant limitations. High quality, well-positioned images are essential to maximise the diagnostic potential of radiographs. 

A turning point in our diagnostic ability and understanding of neck dysfunction has been the recent adaptation of human CT scanners to allow imaging of the horse’s neck. A number of equine hospitals across the United Kingdom and Northern Europe now offer this imaging modality. We have been providing this service at Liphook Equine Hospital since 2017, with over 150 neck scans performed to date.

The CT procedure

A computed tomography (CT) scan combines a series of x-ray images taken from different angles around the area of interest to create a 3-dimensional volume of imaging data. This data is presented as a grayscale image which can be viewed in any plane and orientation. It provides excellent bone detail, and post processing techniques can provide information on soft tissue structures too. Additional techniques can be employed such as positive contrast myelography to provide greater detail about soft tissue structures. Myelography delineates the spinal cord using contrast medium injected into the subarachnoid space and is indicated in any case showing neurologic signs suggestive of spinal cord compression. 

Neck CT is performed under a short general anaesthetic. Scans without myelography typically take less than 20 minutes to complete. The entire neck is imaged, from the poll to the first thoracic vertebra. The procedure is non-invasive and low risk, with anaesthetic-related complication presenting the main risk factor to the procedure. We have not encountered any significant complications in our plain CT scan caseload to date. Horses showing ataxia, weakness and incoordination (Wobbler’s), undergo CT myelography which adds around 20 minutes to the procedure. These horses are exposed to a greater level of risk due to their neurologic condition, the injection of a contrast agent and the increased chance of destabilising a more severe lesion during the procedure.

CT is revealing more detailed information about ways that spinal cord compression can occur in Wobbler cases, about compression of spinal nerves resulting in forelimb gait deficits and precise detail about fracture configurations. It gives us detailed images of articular process joint disease, intervertebral disc disease, developmental conditions and anatomic variations. It is also revealing information about rare diseases such as vertebral abscesses or spinal neoplasia. As our caseload and confidence in the imaging modality grows, we are learning more about the value of CT in examining more subtle neck conditions. We are also bringing the benefit of a more accurate diagnosis, allowing precise targeted treatment and a better ability to provide a prognosis about outcomes—likely progression or safety factors. CT myelography allows circumferential imaging of the spinal canal and yields significantly more information than traditional x-ray myelography. As a result, we hope to enable better case selection of horses that may benefit from Wobbler surgery, with the goal of resulting in improved success rates of the surgery.

Innovations in treatment

New treatment options are emerging as a result of our more accurate diagnoses of neck pathology. Of the first 55 horses which underwent neck CT at our hospital, we were surprised to discover that 13 (24%) had some form of osteochondral fragmentation within the articular process joints of their neck. Some of these horses were young Thoroughbreds, bred to race but showing Wobbler signs. These tended to have convincing CT evidence of type 1 CVM (Wobbler Syndrome) and osteochondrosis affecting their neck. Others had fragments which were larger and more discrete, with evidence of articular process joint enlargement/arthritis but no other bony lesions. These horses were typically older and of a range of breeds and uses. 

In those horses presenting with signs of neck pain but no neurologic deficits, surgical removal of these fragments was proposed. Following further consideration and cadaver training, we have begun to offer this surgery for horses that fit the appropriate criteria and have surgically accessible fragments.  We have performed arthroscopic or arthroscopic-assisted fragment removal from eight articular process joints in six horses to date. No intraoperative or postoperative complications have been encountered; and five of six horses showed complete resolution of neck pain. In the sixth horse, full recovery was not anticipated due to the presence of additional neck pathology, but partial improvement occurred for two years.  Fragment removal has relieved signs of neck pain and stiffness and caused improved performance in these horses. 

Two procedures that are emerging to treat spinal nerve root impingement are a targeted peripheral nerve root injection and a keyhole surgical procedure to widen the intervertebral foramen. Nerve root injection is performed in the standing sedated horse under ultrasound guidance. Surgery is performed under anaesthesia, using specialised minimally invasive equipment to widen the bony foramen using a burr. This surgery is in its infancy but offers an exciting treatment option.  

Additionally, CT gives us the ability to better plan for fracture repair, undoubtedly improving our case selection for Wobbler surgery; it more accurately guides intra-articular injection of the articular process joints. 

Summary

Computed tomography is transforming our ability to diagnose conditions of the horse’s neck. The procedure is low risk and now widely available in the UK and other parts of Europe. It is driving the innovation of novel treatment options with the goal of improving outcomes and reducing losses to conditions of the neck. Our CT findings are posing new questions about neck function, pain and neurologic disease and is an active area of ongoing research.

Anatomy of the cervical vertebrae

The neck vertebrae of the horse

The neck consists of seven cervical vertebrae which form a gentle S-shaped curve to link the skull at the poll to the thoracic vertebrae of the chest. Its primary functions are to protect the spinal cord, support the heavy weight of the head and to allow a large range of movement so that a horse can monitor his environment and run at speed, both being vital to this prey species. 

The first (atlas) and second (axis) cervical vertebrae are highly adapted to allow head mobility. The third to sixth vertebrae are very similar in shape, whereas the seventh is shortened as it starts to show similar features to the vertebrae of the thorax. The typical cervical vertebra consists of a cylindrical column of bone (vertebral body) articulating with adjacent vertebrae via an intervertebral disc. 

Running along the upper surface of this bony column is a bony canal created by the vertebral arch. This canal protects the spinal cord and associated structures that run through the centre. Above and to the side of the spinal canal sit the paired articular processes and below; and to the side sit the transverse processes. These are bony prominences to which muscles attach. The soft tissues of the neck are complex and intrinsically linked to the forelimbs and entire axial skeleton.  

The articular processes also form the articular process joints (facet joints) which create an additional two joints between each vertebra. Although highly adapted, these joints are similar to others in the body consisting of cartilage-lined surfaces, a joint capsule and joint fluid. The joint surfaces are oval in shape, approximately 3-4cm in diameter and sit at an oblique angle to the neck. They provide important additional support and mobility to the neck.
