The Role Vitamins Play in the Diet
Vitamins are a key part of the diet for racehorses and although the clinical signs associated with an overt deficiency or excess of one vitamin or another are rare, we should not presume that the level of vitamins provided in the diet is optimized for performance. Horses are, generally speaking, quite tolerant of sub-clinical deficiency or excess with regards to vitamins, and the margin of acceptable intake to prevent health issues is therefore relatively wide in most cases. However, maintenance of health is a separate issue compared to optimal performance, which is the ultimate target for horses in training.
