Which products and services should trainers be using in 2023?

Cavalor - ArtiTech

Low-grade inflammation is common in joints that perform. However, joint inflammation initiates a cascade of catabolic reactions that gradually degrade the cartilage and may result in lameness.

Cavalor - ArtiTech

During an extensive research program, Cavalor has designed a multi-ingredient nutraceutical that helps with protecting joints of equine athletes. The effectiveness of Cavalor ArtiTec has been documented by both in vitro and in vivo experiments and the overall efficacy in the treatment of lameness is supported by the results of a clinical pilot study.

The efficacy and especially the synergistic potential of the individual raw materials and botanical ingredients on inflammation, cartilage protection and repair has been studied over 7 years. These findings have led to the final formulation of Cavalor ArtiTec.

Combining botanical ingredients is a widely applied practice to compose effective products. The final result is believed to be of similar or better potency as that of a single herb. The advantage of using suboptimal efficacious dose levels of each botanical ingredient is reducing the risk of potential toxicities associated with the usage of single herbs.

In the follow-up of the results of previous studies, 7 candidate formulations were evaluated (in vitro) to further unlock the mechanism of action of these formulations and their efficacy. The influence on various biomarkers related to joint health and homeostasis were evaluated using primary human chondrocytes isolated from knee joints in various in vitro models. This study has led to the development of the final candidate formulation for evaluation in a combined mechanistic and efficacy horse specific joint inflammation model (Phase III).

In conclusion, Cavalor ArtiTec is a complete multi-ingredient nutraceutical with proven efficacy for optimising joint health in equine athletes. Cavalor ArtiTec delivers everything our equine ‘athletes’ deserve during periods of intense activity and stress.

Duggan Veterinary - ConfidenceEQ®

Pheromone communication has been at the heart of Duggan Veterinary Supplies expertise for over 40 years, and we are now pleased to announce the launch of the innovative equine appeasing pheromone, ConfidenceEQ®.

Duggan Veterinary - ConfidenceEQ®

A pheromone is a naturally occurring chemical that an animal produces used for intraspecies communication, which means that their presence automatically and predictably affects all members of the same species, regardless of age or gender.

Like many mammals, nursing mares naturally emit a calming pheromone that reassures their newborn foal. When the foal encounters unfamiliar situations and uncharted territory, this pheromone makes the foal feel comfortable, secure, and more self-assured, enabling them to better learn about their surroundings. ConfidenceEQ® is an identical replica of this horse appeasing pheromone. Numerous studies have been conducted since the equine appeasing pheromone was discovered, proving its effectiveness in reducing stress in conditions that occur frequently in horses of all ages.

Donal Duggan is delighted to add ConfidenceEQ® to the Duggan Veterinary Equine armoury, stating: “The ideal time to use ConfidenceEQ® is when you anticipate your horse will be exposed to something new which they may find stressful. ConfidenceEQ® helps reassure horses, helping them focus allowing them to use their own skills to cope with their surroundings and can be used to help build confidence in situations such as: Loading, travelling and recovery after arrival; Environmental changes (new yard, stabling) or competition environment; Social situations (weaning foals, meeting new horses); Dealing with loud noises (large crowds, thunderstorms, fireworks); Breaking young horses and introducing new exercises during training; Farrier, vet, or dental visits.”

Horses in these situations may show signs of stress such as pawing, vocalising, flared nostrils, kicking, lack of concentration, and resistance. These behavioural changes are due to an elevated cortisol level, which when prolonged, also triggers multiple physiological responses like increased heart rate and blood pressure, weakening of the immune system, cribbing, and digestive issues - all of which can develop into significant problems for owners, trainers, and veterinary practitioners.

ConfidenceEQ® is easy and quick to apply. There are no syringes, mixing food, pills or other uncomfortable application methods that can be difficult to administer or add stress to your horse. It takes effect in 30 minutes, lasts 2.5 hours, and can be reapplied as needed.

Freedom Health - Total Gut Health

Horses actively training and racing commonly struggle with digestive health, problems which manifest most obviously in gastric issues. Additionally, many racehorses experience concurrent hindgut problems less easily recognised. Not eating well, sudden changes in behaviour, resistant and mean attitudes, not fully using the body, and struggling to maintain weight and condition are a few of the problems that can be associated with hindgut health.

Freedom Health - Succeed

It’s important to actively manage the health of the horses’ entire digestive tract to stop the treat-and-repeat cycle and keep your horses in top condition. A healthy gut is a core requirement for a racehorse to perform to its full potential.

Unfortunately, training, travelling, racing, and breeding chronically stress the horse and especially the digestive tract. Management and feeding practices have changed beyond recognition over the last few decades. But the equine digestive tract remains the same, having been accustomed to a low-stress, nomadic lifestyle while consuming a high-fibre, trickle-fed diet. Modern husbandry practices and feeding grain-based feeds, further complicated by competition stresses, can be significant contributors to digestive issues. What, then, can you do for these horses?

Freedom Health - Total Gut Health

Support total digestive health by feeding SUCCEED® Digestive Conditioning Program™ once a day every day. SUCCEED maintains optimal digestive health in athletic horses naturally with science-based, human-food-grade quality, proven ingredients. It serves as an ongoing maintenance program for the health of the entire digestive tract.

Product trials available on a limited basis. Contact Sandra Hughes: shughes@freedomhealthllc.com.

SUCCEED® Digestive Conditioning Program™

The patented and proven SUCCEED formula delivers nutrients the body requires for GI anatomy and function. It provides a variety of benefits including:Oat Oil – specially extracted to preserve polar lipids which support nutrient absorption and bioavailability; Oat Flour – specially processed to preserve ß-glucan, a soluble fibre that provides support for a healthy immune system and a normal, healthy rate of feed transit through the GI tract; Yeast – a combination of a mannan oligosaccharide and a yeast ß-glucan help maintain a healthy, balanced hindgut and natural immunity; Amino Acids – provide fuel for muscles and support production of mucin, a necessary component of the mucus that lubricates and protects the gut lining.

“I have been using SUCCEED, and I couldn’t be happier with the results. You can visually see a big difference in the horses’ condition very quickly. I believe that it is really enabling their digestive systems.”

Plusvital - Racing Syrup

The globalisation of racing has eroded the margins of success between trainers. High performance is no longer guaranteed based on pedigrees. A study carried out on winning margins in racing suggests that the overall percentage difference between first place and second place  is 0.32%, the difference between first and third was 0.75%. Never before has optimising recovery and nutrition been as important in gaining percentages of improvement which can be the difference between winning and not. 

Plusvital - Racing Syrup

Days post-race or fast work the body recovers and adapts allowing the horse to become more oxygen efficient and physically stronger. Muscle recovery requires specific vitamins, minerals and amino acids to give the horse the best possible opportunity to maximise its full potential. This vital edge is optimised by correct nutrition. Supporting race horses' mineral and vitamin levels is critical to racing success today. 

Used for 47 years by global racing elite Plusvital Racing Syrup is formulated to provide 30 essential vitamins and minerals exceeding NRC recommendations. Key ingredients facilitate strength and recovery.  

B vitamins are an essential group of vitamins for a horse to perform at its best. The harder they work the higher the requirement for vitamin B is. B vitamins play a vital role in forming red blood cells, responsible for carrying oxygen to muscles allowing the horse to continue galloping at high intensity whilst removing carbon dioxide. When muscle has a high level of carbon dioxide the horse becomes tired and cannot finish the race.

Additional key ingredients include Vitamin E which reduces oxidative stress. Selenium neutralise free radicals supporting the immune system. Branched chain Amino acids and Threonine supports muscle recovery essential for strengthening. Zinc and biotin support cellular repair and hoof growth. Available in 2L or 5L Plusvital racing syrup supports your horse in pursuit of their performance goals.

Why Choose Pro-Dosa in 2023?
As we all know, horsemen are responsible for the management of horses’ health, wellbeing, and fitness, to ensure they can perform to the best of their ability on the racetrack, but at the same time, a racing stable must be a profitable business and each horse must be economically viable for their owners.  As a result, in 2023, more than ever, horsemen must ensure they are getting the best possible value from the products they purchase.

Pro-Dosa

Quite logically, horses under the added stress of hard work, transport, racing, competition, or illness have increased nutrient requirements.  Unlike people though, who often turn to food when under stress (think chocolate or chardonnay), horses tend to go off feed and drink less than they normally would.  Horses that fail to eat or drink well when travelling and racing will recover more slowly and will often perform below their best.  That is why many stables consider traditional, veterinary-administered, injectable pre-race/pre-travel treatments to be essential. Corrine Hills says “I originally developed Pro-Dosa BOOST, for horses in my own racetrack veterinary practice, as a more economical, less invasive, oral alternative to those treatments.”

Pro-Dosa BOOST is a complete, balanced multi-nutrient paste that I formulated to fill the gap between good daily nutrition and the increased requirements horses have when they are under stress. Pro-Dosa BOOST provides a practical way to deliver essential nutrients to horses that may not be eating or drinking enough, at those times, to support normal metabolism, performance, recovery, and heath.  

It contains a comprehensive range of water-soluble vitamins, trace elements, electrolytes, and amino acids in doses that reflect requirements established in scientific literature.  I have included them in readily usable forms, in good balance with each other, and in balance with the cofactors required for their absorption and function.”

Pro-Dosa International Ltd is GMP registered, demonstrating quality, safety, and security of the product from raw materials through to finished product.  Each batch of Pro-Dosa BOOST undergoes laboratory testing including complete quantitative analysis, demonstrating that each portion contains precisely what is on the label; microbial cultures, to ensure it is safe to feed; and Naturally Occurring Prohibited Substance screening.

SPILLERS™ - Perform & Restore Mash

Racehorses need optimum nutrition to help them fulfil their full potential which is why SPILLERS™ has launched their new SPILLERS Perform & Restore Mash. The mash soaks super-fast in under 2 minutes providing convenience especially when travelling and is designed to be fed daily to support optimum condition and recovery.  It’s been formulated to assist hydration and complement the replacement of electrolytes post exercise.  Re-hydrating quickly is important particularly for horses in high intensity exercise as they rely heavily on muscle glycogen (stored glucose) for energy metabolism and although it takes up to 72 hours for glycogen stores to be fully restored, replenishment will be slower in dehydrated horses. 

SPILLERS™ - Perform & Restore Mash

SPILLERS Perform & Restore Mash is a low starch, molasses free blend of highly digestible fibre and oil to support digestive health and includes probiotic live yeast alongside prebiotic MOS and FOS.  The mash offers a high level of the essential amino acid lysine to support muscle tone and topline and includes branch chain amino acids to support muscle synthesis post exercise. What’s more, it supplies powerful antioxidants including vitamin C to support respiratory health and natural, bioavailable vitamin E to support immunity, muscle health and an athletic performance. 

Finally, SPILLERS Perform & Restore Mash includes an appetising apple aroma which is released when soaking to encourage even the fussiest of fussy feeders. 

All SPILLERS feeds are BETA NOPS approved.

Fairfax - Better condition – better performance

Resolve to make 2023 the year you take a closer look at the exercise tack your horses wear on a daily basis – and follow the science when it comes to making choices that will improve performance.

Switching saddles could significantly improve a horse’s back health and movement, as well as reducing time off and vet bills this year. In scientific trials commonly-used exercise saddles (1/2 tree, 3/4 tree, and full tree) all caused areas of potentially detrimental high pressure. The Fairfax Exercise Saddle relieves pressure at a crucial point on the back (T13) so in gallop the hindleg is brought forward more and the quarters come further under the horse. The proven result is increased stride length and therefore more power.

If a horse is girthy or aggressive when being tacked up, consider the girth it wears on a daily basis. When straight girths were tested at gallop on a treadmill, the pressure was so high that the pressure mat was unable to record it. To achieve a significantly freer gallop with increased hindlimb extension, make the switch for 2023 to the Fairfax Race Exercise Girth which is shaped to avoid a peak pressure zone behind the elbow. It may also be an effective part of a multi-disciplinary approach in supporting horses with ulcers.

You could reduce or eliminate sore or rubbed withers this year by using a medical-grade closed-cell foam pad with a shaped central webbing spine. The Fairfax Race Exercise Pad provided superior pressure reduction without slipping in a pilot study where foam, gel and polyfill pads were compared. Gel pads increased pressure at the front of the saddle and those without a central spine (such as polyfill pads) slipped down onto the back at speed. In addition, using multiple polyfill pads does not relieve pressure – it increases bulk and instability. 

Scientists have proven that changing to a bridle that reduces pressure at the TMJ has a significant positive effect on the horse’s power, straightness and efficiency of stride. This is because the TMJ area is massively influential when it comes to locomotion. The Fairfax Race Bridle relieves pressure at the TMJ and other areas on the face resulting in improved front and hindleg range of motion. In addition, the Mexican grackle helps keep the bit stable in the mouth reducing sores and hanging associated with bridle pressure.

Bloomfields - Professional Raceline

This is the ultimate horsebox for young or difficult horses, stallions, & bloodstock.

Designed and precision engineered in the UK specifically for the transport of Bloodstock, the unmistakable & seamless Bloomfields Professional Raceline oozes class & elegance as well as its evident suitability for the industries demands.

Bloomfields - Professional Raceline

A twist to our popular Professional model, which has been a market leading design used by amateurs and professionals throughout the world for over 15 years, we have designed with the involvement of industry experts to meet the needs of the end user, comfort and practicality for both the travelling staff and the horses.

The Professional Raceline is fitted with our one piece composite floor. Sliding partition, wall, door and roof padding is fitted as standard for superior comfort of the horse. Our woven, thermally bonded panels, doubled with our captive design are, in our opinion, the strongest on the market, but for extra peace of mind we also add an aluminium kick board throughout the horse area.

Bloomfields have designed and developed a slam locking system for the individual doors to each horse. Knowing that some travellers can be difficult, this gives super easy exit and entry to the grooms area without needing to bend down in front of the horses. Our Double catch slam locks make shutting the doors effortless and safe plus super easy access to each horse for easy preparation.

A very popular option for the Professional Raceline is the exquisite sliding partition. Absolutely indispensable for transporters and studs who carry mares and foals. Effortlessly glide the full height partition to the far wall with one hand and back to the centre point when required, meaning there is no need for more than one person to alter the stalls. Our 4 point locking system adds superior strength when in the central position.

The seamless under-sprung ramp gives a progressive lifting pivot meaning opening and closing the ramp is effortless. We never use gas rams, meaning the weight of the ramp will not change from the day of purchase.

What sets the Raceline apart from any other is the careful consideration into the practicality of the grooms area and how it can be a useful and resourceful place for storing everything from tack to veterinary medication and water barrels. Thorough research was undertaken to maximise the use of the space in the grooms area, with this in mind we have the option of a washable removable Hammock that is, as standard, mounted securely on the bulkhead. This allows travelling staff to relax without taking up essential weight or space.

One of the main factors considered when designing the Raceline was to put preventatives in place for cross contamination, particularly in the racing industry this is essential, So we have, as standard, supplied individual storage compartments for racing equipment & feed etc.

With safety in mind, believed to be the safest way to travel horses, The horses are separated by means of a full height, grilled partition, head divider, two full height grilled access doors, eliminating the need for a breast bar. The professional Raceline comes fully padded with an oversized rear door and dual reinforced glass fibre and Coat-X coated wheel arch covers. 

With an expansive list of optional extras to suit almost any requirement, including the 4.5t crewcab option in 2023, the Bloomfields Professional Raceline is the first and only form of 2 horse transportation you’ll need.

Our Professional Raceline is used throughout the world by professional transporters and riders, proving the strength and durability is second to none.

Small wounds leading to synovial infections

Operating on a synovial infection wound.jpg

Article by Peter Milner

Most experienced trainers will know from bitter experience that a seemingly tiny wound can have a big impact if a horse is unlucky enough to sustain a penetrating injury right over a critical structure like a joint capsule or tendon sheath. Collectively, joints and tendon sheaths are called synovial structures, and synovial infection is a serious, potentially career-ending and sometimes life-threatening problem. 

A team of veterinary researchers from Liverpool University Veterinary School, published a study in Equine Veterinary Journal that examined factors influencing outcome and survival. This article was first published in European Trainer (issue 50 - summer 2015) but is being republished due to popular demand.

What is synovial infection?

Infection involving a synovial cavity, such as a joint or tendon sheath, is a common and potentially serious injury for the horse. The most prevalent cause is a wound, although a smaller proportion of cases result following an injection into a joint or tendon sheath, or after elective orthopaedic surgery to the area. Additionally, infection can occur via the bloodstream, particularly in foals that have not received enough colostrum.  Left untreated, the horse will remain in pain, and ongoing infection and inflammation can result in permanent damage. This can ultimately result in euthanasia on welfare grounds. 

What factors are important for horse survival?

synovial infections in Thoroughbred's.jpg

When a synovial infection occurs there is a huge inflammatory response, leading to swelling and pain. The horse usually shows severe lameness but following a good clinical examination, the cause is often quickly identified.  Prompt veterinary recognition of involvement of a joint or tendon sheath and aggressive treatment (involving flushing the affected synovial cavity and the correct use of systemic and local antibiotics) will often result in a good outcome for the horse.  Flushing removes inflammatory debris including destructive enzymes and free radicals, and it eliminates contaminating bacteria in most cases. This is performed most effectively by arthroscopic guidance (“keyhole” surgery) under general anaesthesia. Using a “scope” to do this is considered superior to flushing through needles because arthroscopy allows the inside of the problem area to be inspected, foreign material (for example, dirt or splinters of wood) to be removed, and any concurrent damage (such as damage to the cartilage or a cut into a tendon) to be evaluated. In addition, targeted high volume lavage is best achieved via arthroscopy. 

Survival following arthroscopic treatment of synovial sepsis is good – approximately 80-90% of adult horses undergoing a flush are discharged from hospital.  In foals, however, the figure is much lower, at around 55%, and this likely due to complicating factors such as concurrent sepsis involving multiple organs.  Our study, recently published in Equine Veterinary Journal, investigated what factors might be involved in determining survival to hospital discharge in 214 horses undergoing arthroscopic treatment for synovial sepsis. We used statistical modelling to evaluate the interactions with different factors at three key time points during the management of the condition at Liverpool Veterinary School, one of the leading UK referral veterinary hospitals. Information collected on admission to the hospital included when the horse was last seen to be normal, the cause of the infection, the degree of lameness present, and the level of white blood cells and protein in synovial fluid collected from the infected joint or tendon sheath. These lab tests are an important method which veterinarians use to determine how severe the infection is. Additional data collected included whether the surgery was performed out-of-normal working hours, if foreign material was present, the amount of inflammation present in the area, and whether any additional cartilage or tendon damage was found at surgery. Post-operative information gathered included what the levels of white blood cells and protein were in the synovial fluid after surgery and whether the horse needed further surgical treatment.

All horses in this study were greater than six months old and the majority had sustained a wound that communicated with a joint or tendon sheath.  Eighty-six per cent of the 214 horses admitted to the hospital survived to hospital discharge.  Of the 31 horses that did not survive, 27 were euthanised due to persistent infection or lameness.

An angry, protein-soup

A high level of protein in the synovial fluid of the affected joint or tendon sheath on admission and levels that remained high after surgery were strongly associated with a poor outcome and loss of the horse.  Protein concentrations are normally fairly low in a normal joint or tendon sheath, but protein leaks into the synovial cavity from surrounding blood vessels when inflamed. Protein is also produced by cells in the synovial cavity when they are activated in response to a severe insult such as infection. Protein clots trap bacteria in the joint, making it harder to remove infection. The protein soup also includes lots of inflammatory mediators such as enzymes and signalling molecules, and these cause further inflammation, tissue damage, and sensitise pain receptors in the synovial cavity magnifying the inflammatory response and increasing the pain experienced by the horse. Unchecked, this angry, inflamed environment can result in cartilage degeneration, bone damage, and adhesion (scar) formation. This fits well with another observation from this study linking the presence of moderate or severe synovial inflammation at surgery as a negative factor for survival. 

Small wounds can lead to big trouble

Interestingly, horses presenting with an obvious wound (as opposed to a small penetrating injury or no visible wound) were more likely to survive to hospital discharge. This may be due to the injury being noticed earlier and hence prompting earlier veterinary intervention. Alternatively, open wounds may allow drainage of inflammatory synovial fluid and lessen the detrimental effects of increased pressure within the joint as well as reducing ongoing exposure to inflammatory mediators. This finding highlights the fact that trainers should act promptly when faced with a wound – it is easy to underestimate just how much damage may be going on under the surface.

arthroscopic treatment of synovial sepsis.jpg

Horses undergoing surgical treatment of a joint or tendon sheath infection out-of-hours (for example in the middle of the night) were three times less likely to survive to hospital. Often, horses with a synovial infection arrive stressed and painful and not in an ideal state for having an anaesthetic. Early identification of an infection and appropriate management is important but stabilisation of the horse and preparation for surgery appear to outweigh any perceived benefits of undertaking immediate surgery.  This is borne out by the finding that time from initial injury to treatment was not associated with outcome and is in agreement with previous findings from other researchers. It is important to reiterate that prompt recognition and treatment of a horse with an infection in a synovial cavity is essential but that surgical management within 12-24 hours of diagnosis, so that the horse is in the best condition for undergoing anaesthesia, does not affect outcome. 

Do horses return to work after a synovial infection?

arthroscopic treatment of synovial sepsis.jpg

The big question that owners and trainers want to know is whether the horse will regain full function of the joint or tendon sheath after having an infection. Figures for return to function following surgical (arthroscopic) treatment for a synovial infection vary between 54-81%.  Various factors appear to relate to outcome but when looking at a predominately thoroughbred racing population, the statistic for return to training appears to be at the higher end of this range. Factors associated with failure to return to athletic performance include the presence of thickened inflammatory tissue (known as pannus) at the time of surgery and that may relate to the development of fibrous adhesions and scar tissue within joint or tendon sheath longer-term. Some structures are particularly likely to compromise future function, and horses with an infection of the navicular bursa in the foot following a nail penetration generally do worse. 

Take home message

Horses sustaining an infection to a joint or tendon sheath have a good chance of the infection clearing up and surviving the injury, with the likelihood of racing as high as around 80%.  Our key message for trainers from this study is that it is essential that they recognise early when an infection involves one of these structures and have a veterinarian fully evaluate the injury. Aggressive treatment is important and involves flushing the synovial cavity using a “scope” under anaesthesia to remove as much inflammatory and infective debris as possible.

Wobbler Syndrome and the thoroughbred

Wobbler Syndrome and the Thoroughbred Celia M Marr, Rossdales Equine Hospital and Diagnostic Centre, Cotton End Road, Exning, Newmarket, Suffolk, CB8 7NN  << BCET logo near the top>>  Wobbler Syndrome, or spinal ataxia, affects around 2%…

By Celia M Marr, Rossdales Equine Hospital and Diagnostic Centre

Wobbler Syndrome, or spinal ataxia, affects around 2% of young thoroughbreds. In Europe, the most common cause relates to narrowing of the cervical vertebral canal in combination with malformation of the cervical vertebrae. Narrowing in medical terminology is “stenosis” and “myelopathy” implies pathology of the nervous tissue, hence the other name often used for this condition is cervical vertebral stenotic myelopathy (CVSM).

Wobbler Syndrome was the topic of this summer’s Gerald Leigh Memorial Lectures, an event held at Palace House, Newmarket. Gerald Leigh was a very successful owner breeder and these annual lectures, now in their second year, honour of Mr Leigh's passion for the thoroughbred horse and its health and welfare. The lectures are attended by vets, breeders and trainers, and this year because of the importance and impact of Wobbler syndrome on thoroughbred health, several individuals involved in thoroughbred insurance were also able to participate.

Blindfolding the horse, exacerbates the ataxia and improves the accuracy of objective ataxia assessment.

Dr Steve Reed, of Rood and Riddle Equine Hospital, Kentucky and international leader in the field of equine neurology gave an overview of Wobbler Syndrome. Affected horses are ataxic, which means that they have lost the unconscious mechanisms which control their limb position and movement. Young horses with CVSM will generally present for acute onset of ataxia or gait abnormalities, however, mild ataxia and clumsiness may often go unnoticed. Trainers often report affected horses are growing rapidly, well-fed, and large for their age. It is common for riders to describe an ataxic horse as weak or clumsy. Sometimes, a horse which has been training normally will suddenly become profoundly affected, losing coordination and walking as though they were drunk, or in the most severe cases stumbling and falling. Neurological deficits are present in all four limbs, but are usually, but not always more noticeable in the hindlimbs than the forelimbs. In horses with significant degenerative joint disease, lateral compression of the spinal cord may lead to asymmetry of the clinical signs.

When the horse is standing still, it may adopt an abnormal wide-based stance or have abnormal limb placement, and delayed positioning reflexes. At the walk, the CVSM horse’s forelimbs and hindlimbs may not be moving on the same track and there can be exaggerated movement of the hind limbs when the horse is circled. Detailed physical examination may reveal abrasions around the heels and inner aspect of the forelimbs due to interference, and short, squared hooves due to toe-dragging. Many young horses affected with CVSM have concurrent signs of developmental orthopaedic disease such as physitis or physeal enlargement of the long bones, joint effusion secondary to osteochondrosis, and flexural limb deformities.

Radiography is generally the first tool which is used to diagnose CVSM. Lateral radiographs of the cervical vertebrae, obtained in the standing horse, reveal some or all of five characteristic bony malformations of the cervical vertebrae: (1) “flare” of the caudal vertebral epiphysis of the vertebral body, (2) abnormal ossification of the articular processes, (3) malalignment between adjacent vertebrae, (4) extension of the dorsal laminae, and (5) degenerative joint disease of the articular processes. Radiographs are also measured to document the ratio between the spinal canal and the adjacent bones and identify sites where the spinal canal is narrowed.

ABOVE L–R: Lateral radiographs can show the vertebral bones have an abnormal shape with flare of the caudal vertebral epiphysis (curved arrow) and extension of the dorsal laminae (straight arrow). Abnormal ossification of the articular processes and enlargement of the joints due to degenerative joint disease (arrows). Measuring the ratio of the spinal canal to the adjacent bone identifies narrowing of the spinal canal. In this case, the narrowing is dramatic due to mal-alignment of adjacent vertebral bones.

Dr Reed also highlighted myelography as the currently most definitive tool to confirm diagnosis of focal spinal cord compression and to identify the location and number of lesions. The experts presenting at the Gerald Leigh Memorial Lectures agreed that myelography is essential if surgical treatment is pursued. However, an important difference between the US and Europe was highlighted by Prof Richard Piercy, of the Royal Veterinary College, University of London. In Europe, protozoal infection is very rare, whereas in US, equine protozoal myeloencephalitis can cause similar clinical signs to CVSM. Protozoal myeloencephalitis is diagnosed by laboratory testing of the cerebral spinal fluid but there is also a need to rule out CVSM. Therefore, spinal fluid analysis and myelography tends to be performed more often in the US. Prof Piercy pointed out that in the absence of this condition, vets in Europe are often more confident to reach a definitive diagnosis of CVSM based on clinical signs and standing lateral radiographs.

Musculoskeletal injuries are an inherent risk of horseracing, and they are the primary cause of thoroughbreds failing to train and race, or even retiring altogether. In addition to the evident equine welfare concerns, racehorse injuries also have economic consequences and impact on jockey safety. The industry remains committed to investigating causes of injury and associated risk factors, which can inform strategies aimed at minimising their occurrence. Advancements in methods of identification, management, and prevention of musculoskeletal disease and injury in Thoroughbreds and improved training and racing environments to enhance the safety, health, and wellbeing of racehorses have long been strategic priorities of the Horserace Betting Levy Board (HBLB)’s veterinary research funding program in Great Britain.

In 2014, the HBLB funded a research team at the Royal Veterinary College in London to undertake a detailed study of injuries and other veterinary events occurring in flat racehorses on race day. The purpose of the project was to establish causes of fatal and non-fatal injuries occurring in British flat racing and to examine associated risk factors. The research also set out to measure heritability of common injury types and conditions, and to investigate genetic and environmental correlations between injury and race performance.

The study team had access to detailed race and performance data from all Thoroughbreds racing on the flat in Great Britain over a 14-year study period from 2000 – 2013. These were then linked to veterinary reports of injury or conditions attended to by a veterinary surgeon on race day over the same time period, provided by the British Horseracing Authority (BHA). Finally, extensive pedigree data were added to enable investigation of heritability of race day injury and genetic correlations between injury types, and between injury and performance.

Descriptive findings

The final 14-year dataset included nearly 68,000 horses making over 800,000 starts in around 77,000 flat races. The majority of races -- 67% of them -- were run on the turf, with 33% of races taking place on all-weather tracks.

Just under 8,000 veterinary events were recorded over the study period, from which an incidence of nine events per 1000 starts was calculated. The most common incidents requiring veterinary attention on the racecourse were soft tissue injuries other than tendon and ligament injuries, e.g. wounds, lacerations, or muscle strains. Unspecified lameness and respiratory conditions were also common, accounting for around a fifth of veterinary reports each. Less than 10% of veterinary events had a fatal outcome, and the overall incidence of fatality was 0.8 per 1000 starts. Although bone injury was cited in only 14% of the veterinary reports overall, they accounted for the vast majority (77%) of the fatalities.

All-weather racing

Racing on all-weather tracks traditionally carries a higher risk of injury than racing on turf, which was reaffirmed in the current analyses. Therefore, the researchers also specifically investigated risk factors for fatality, distal limb fracture, and epistaxis (nose bleeds) in all-weather racing. These analyses were restricted to the ca. 258,000 all-weather starts in the dataset and included additionally collected information from the racecourse clerks on surface types and maintenance. The fatality incidence in all-weather racing was 0.9 per 1000 starts. Distal limb fracture occurred in around 1 in 1000 starts and epistaxis in 1.6 per 1000 starts. Risk factors varied for each outcome, although some factors were similar across outcomes including the going, racing intensity, horse age, age at first start, and horse and trainer performance variables. Generally, older horses and those that had started racing at an older age were at higher risk of an adverse outcome although for fatality, older horses that had started racing as two-year-olds were at highest risk. This association may be due to accumulation of microdamage in bone, which increases with increasing age as an effect of exercise accumulation over time and can ultimately lead to failure.
