More than 100 horse feed manufacturers, veterinarians, students, and other industry professionals from more than a dozen countries recently attended the 17th Kentucky Equine Research Nutrition Conference held in Lexington, Kentucky. The multi-day meeting featured lectures by international authorities on feeding and management of sport horses in various disciplines such as endurance riding and three-day eventing. Topics included heart rate metrics, drug use guidelines and restrictions, antioxidant research, use of electrolytes for hydration and recovery, management of metabolic and muscle diseases, and the diagnosis and treatment of joint problems in equine athletes. Dr. Joe Pagan, president of Kentucky Equine Research, reviewed clinical studies that have revealed key facts about equine nutrition and exercise physiology. In many cases, this research has led to the development of nutritional products and supplements used by horses competing successfully at the Olympic Games level.
