Abstract: VILLAMOR, CARMELITA IRA, University of the Philippines at Los Bafios, April, 1982. Changes in Rumen Composition in Goats Fee Ipil-ipil (Leucaena Leucoce hales Lam de Wit.) Leaves and Farm-By-Products. Major Professor: Dr. Perla L. Lopez. Sixteen intact female goats were used in a completely randomized design to determine the digestibility of rice straw, ipil-ipil, sugar cane bagasse and dried sugar cane tops. Significantly higher DM intake was obtained with dried ipil-ipil leaves compared with all the other farm by-products (P‹ 0.05). Values obtained for TDN and DE were 55.35% and 2435 kcal, respectively, for rice straw; 55.69% and 2167 kcal, for dried ipil-ipil leaves 62.25% and 3832 kcal for sugar cane bagasse and 50.41 % and 2715 kcal for dried sugar cane tops. Significantly higher DE was obtained for the sugar cane by-products (P<0.05). A separate digestion trial was conducted to determine the digestibility of four ipil-ipil based rations with practically the same level of crude protein and total digestible materials. Four fistulated female goats were rotated in a 4 x 4 latin square design with four treatments and four periods (replicates). Each dietary treatment was made up of 40% concentrate mixture and 60% roughage material, one with pure dried ipil-ipil leaves and the remaining three with an equal proportion of dried ipil-ipil leaves and rice straw, sugar cane bagasse and, sugar cane tops. Significantly higher DM digestibility and TDN values were obtained in the rations containing ipil-ipil and sugar cane by-products (P<0.05). Digestible energy and gross energy digestibility were also significantly higher in rations in which farm by-products were incorporated. Peak of total volatile fatty acid concentration was noted one hour after feeding which was accompanied by the lowest level for pH and vice versa. Significantly higher VBC were obtained with diets 1 and 4 (P40.05) with maximum counts at an hour after the afternoon feeding and minimum counts just an hour before feeding. Total protozoal count was significantly higher in Diet 3 (P40.05) showing decreasing trend following ingestion of feed.Levels of total nitrogen and nitrogen-fractions except urea-nitrogen were not significantly different in all four rations. Increases in non-protein nitrogen, ammonia-nitrogen and urea nitrogen were noted immediately following ingestion of feed. The reverse trend was noted with true proteins in the rumen.
