| 英文摘要 | P>the effect of dietary methionine (met) levels on endogenous n and amino acids (aa) flows at different part of the digestive tract of growing goats was determined using a 15n isotope dilution technique. three goats (25 +/- 2.5 kg) were fitted with the ruminal, duodenal and ileal cannulae and allocated to three dietary treatments in a 3 x 3 latin square design. the dietary treatments consisted of a total mixed ration containing three levels of met (0.15%, 0.25% and 0.35%) respectively. it was found that at 0.15% met level, the lowest flow in endogenous n and total aa at the duodenum and ileum occurred. the endogenous n secretion contributed to 26% and 23% of the duodenal and ileal total n flows, respectively, and the proportions were not affected by the dietary met levels. the duodenal and ileal flows of endogenous total aa were 11.1, 11.8, 11.3 g/d and 2.9, 3.9, 4.1 g/d respectively. the average real digestibility of n was 65%, 87% and 95% in the forestomach, intestine and whole digestive tract respectively. |
