Abstract
Six pony geldings were fitted with ideal cannulas and used in a 6 x 6 Latin square experiment. Diets consisting of 65% concentrate and 35% bermudagrass hay were fed at 12 h intervals. The concentrate contained 0, 5,10,15, 20 or 25% rendered animal fat. The ponies were fed at a constant intake throughout the experiment. The ponies were fed each diet for 1 0 d of adjustment followed by 4 d of collection during each period. Feces and ileal fluid were collected over the 4-d collection period. The collections from the ileum were taken 3X daily to represent each 2 h interval following feeding. The ileal fluids were composited on an equal volume basis into one sample per horse per treatment. Fifteen percent of the total feces within each collection period were saved for analyses. Feed and hay samples were also collected. The feed, hay and fecal samples were analyzed for dry matter, energy, crude protein, neutral detergent fiber and ether extract. The ileal samples were analyzed for dry matter and ether extract content. Upper and lower intestinal digestibilities were calculated from the change in ratio of nutrient to indigestible indicator. The fat added to the diet had no effect on the apparent digestibility of energy or crude protein. Apparent digestibilities of neutral detergent fiber
