Abstract
High-grain diets for the exercising horse were compared with diets which provided 15% of the total caloric intake from either vegetable oil or a highly fermentable fibre source (beet pulp).
Blood glucose was lower (P < 0.05) in the FAT-fed horses during the 3 h post feeding as compared to either CONTROL or FIBRE-fed horses. Insulin was lower (P < 0.05) in the FAT-fed both post feeding and throughout exercise. Cortisol was lower (P < 0.05) in the FAT than the CONTROL-fed during exercise. Following exercise, the FAT-fed drank more water (P < 0.01) than either CONTROL or FIBRE-fed. Substituting 15% of DE as vegetable oil had a greater effect on metabolic response to exercise than a 15% substitution of beet pulp.
