摘要
本试验采用尼龙袋技术测定了枯草期芨芨草叶片经碱处理后,饲料中性洗涤纤维(NDF)和酸性洗涤纤维(ADF)在绵羊瘤胃中的降解率。试验结果表明,用碱液浸泡芨芨草叶片12h,饲料NDF和ADF有效降解率分别为53.59%和48.78%,较原样提高25.68%和25.58%,差异极显著(P<0.01),浸泡12h与24h相比差异不显著(P>0.01)。
Nylon bag technique was used to investigate the effect of alkali treatment on the degradabilities in rumen of NDF and ADF in dry leaf of Achnatherum splendens.The results suggest that the effective degradability of NDF and ADF are 53.59% and 48.78% respectively by immersing the dry leaf of Achnatherum splendens. in lye for 12 hours, which are increased dramatically by 25.68% and 25.58% respectively(P<0.01) compared with the dry leaf of Achnatherum splendens.There are no significant difference in the degradability of NDF and ADF between the dry leaf of Achnatherum splendens immersed in lye for 12 hours and that of 24 hours(P>0.05).
