Area of Science:

  • Equine Nutrition
  • Animal Science
  • Sports Nutrition

Background:

  • Performance horse nutrition requires careful consideration of energy, protein, and vitamin E.
  • National Research Council (NRC) updated energy requirements for racehorses in 1989, which recent studies support.
  • Factors influencing energy needs highlight the importance of monitoring horse body weight and composition.

Purpose of the Study:

  • To discuss optimal nutrition for performance horses.
  • To evaluate current recommendations for energy, protein, and vitamin E intake.
  • To explore the impact of dietary components on exercise physiology and health.

Main Methods:

  • Review of existing literature on equine nutrition and exercise physiology.
  • Analysis of National Research Council (NRC) guidelines and recent research findings.

Related Experiment Videos

  • Discussion of dietary strategies for energy, protein, and vitamin E supplementation.

    • Main Results:

    • Energy requirements for racehorses have been reasonably updated by the NRC; body weight and composition are key indicators.
    • A balanced diet including carbohydrates, fiber, fat, and protein is crucial; excessive protein may impair performance.
    • Current vitamin E recommendations (80 IU/kg) may be higher than necessary for preventing exercise-induced peroxidation but could be relevant for immune function.

    Conclusions:

    • Dietary energy, protein, and vitamin E management significantly impacts performance horse health and athletic capability.
    • Supplemental histidine or carnitine offers limited benefits for horses on conventional diets.
    • Further research is needed to fully understand the role of vitamin E in equine neurological conditions and immune response.
