In today’s industry where seconds mean the difference between 1st and “also ran” at the track, our equine athletes must retain a competitive edge. Renewed interest in research about the performance horse’s nutrient needs has allowed horsemen to feed the athletic horse more scientifically than ever before to maintain that edge. Horses can be selected, bred, managed and fed as athletes. However, because knowing the horse’s individuality and nutrient needs is very important, the horseman’s skill in feeding the horse will never be totally replaced, no matter how precise the feeding recommendations.
