摘要
用体格健壮的10头装有永久性瘤胃瘘管的山羊,采用尼龙袋法对干苹果渣和加酶(3‰比例)苹果渣在瘤胃0,6,12,24,48,72h的降解品质进行研究。结果表明,苹果渣组和加酶组瘤胃粗蛋白质和干物质(DM)动态降解率差异不显著(P>0.05);48h酸性洗涤纤维(ADF)降解率差异显著(P<0.05);72h中性洗涤纤维(NDF)降解率差异显著(P<0.05),提示干苹果渣的蛋白质利用率较高,酶可有效提高苹果渣中纤维的降解品质。
A total of 10 able-bodied goats fitted with permanent rumen fistula were used in the present study, and were randomly divided into two groups, namely, Group Ⅰ dealing with dry apple pomace and Group II dealing with the apple pomace added 3 ‰ of compound enzyme. The degradation quality of Group Ⅰ and Ⅱ were determined at 0, 6, 12, 24, 48 and 72 h in rumen. The results showed that the dynamic degradation rates of crude protein and dry matter （DM） between Group Ⅰ and Ⅱ did not show significant difference （P 〉 0.05） ; the degradation rates of acid detergent fiber （ADF） at 48 h and neutral detergent fiber （NDF） at 72 h between the two groups were significantly different （P 〈 0.05 ）. All the results indicate that the protein utilization of dry apple pomace is very high; the degradation quality of fiber can be improved by adding compound enzyme in apple pomace.
