Evaluation of protein and energy values of Saccharina using ileorrectostomized pigs

Two experiments were conducted to study ileal and total tract digestibility in pigs given levels of 0, 10 and 20% of enriched sugar cane meal (Sacchar ina) in diets based on maize and soybean meal. In trial 1 or 2, three ileor rectostomized or six intact pigs weighing 53 or 55 kp were randomly alloted to three diets according to a single or duplicated 3 x 3 Latin square desi gn. A significant decrease in ileal and total tract digestibility of nutrie nts and energy Nas found on increasing the Saccharina in the diet. The cont ribution of the large intestine to the digestion of diets ranged from 13.4 to 15.5% of the energy that disappeared in the digestive tract. Ileal and t otal tract digestibility of N (39.9 and 45.4%) and energy (27.5 and 37.1%) from Saccharina as calculated by difference indicated that the inclusion of Saccharina in the diet had a depressing effect on ileal digestibility and on total tract digestibility.
