[Supplemental fat in the diet of horses...is it advantageous?].
Feeding fat-supplemented diets to horses has drawn considerable interest. One of the advantages of such diets is that the energy density is increased, so that less feed is needed to meet energy requirements. In addition, adding fat to the diet enhances the contribution of fat oxidation to energy production, thus sparing muscle glycogen. The 'spared' glycogen is available for energy metabolism when the acutely exercising horse reaches a point of oxygen deficit and must rely on anaerobic metabolism. This appears to be beneficial for both aerobic and anaerobic performance. Fats are readily digested by the horse. Vegetable oils are more palatable to horses than animal fats, but the palatability of fat-rich diets may decrease in the long term.
