摘  要:
选用9只体况良好,体重23~25kg的2岁安装有永久性瘤胃瘘管、十二指肠瘘管和回肠瘘管的内蒙古白绒山羊半同胞羯羊进行试验,试验采用随机区组设计,3个组试验羊灌注相同水平氨基酸、不同水平的葡萄糖,使进入绒山羊十二指肠的各种氨基酸(日粮氨基酸+灌注氨基酸)达到M 85+C15(即85%的肌肉和15%的绒毛氨基酸模式)的理想氨基酸模式,1、2、3组的代谢葡萄糖水平分别为35.56、55.56和70.56g/d。结果表明;本试验条件下,随代谢葡萄糖水平的提高,NEAA及EAA中Lys、ArgI、lu、Val、Phe的表观消化率降低,2、3组明显低于1组(P<0.05);2、3组之间差异不显著(P>0.05)。

摘  要:
Nine wethers of Inner Mongolian white cashmere(IMWC) goats(23~25kg) with the same father,fitted with permanent cannulas in the rumen,at the proximal duodenum and terminal ileum were used to investigate the effect of dietary MG levels on AA digestion and absorption in the small intestine of IMWC goats.The treatments were three MG levels in a diet with M85+C15 ideal amino acid pattern,which were 35.56(group 1),55.56(group 2)and 70.56g/d(group 3),respectively.The results showed that the average apparent digestibility of Lys,Arg,Ilu,Val and Phe of EAA and NEAA in the small intestine significantly decreased with dietary MG levels increased(P<0.05),but had no significantly difference between group2 and group 3(P>0.05).
