本试验旨在研究食叶草的营养价值及其在肉羊瘤胃中的降解特性,为食叶草在反刍动物饲粮中的应用提供依据.在采用化学分析法测定食叶草常规营养成分含量的基础上,采用尼龙袋法,以装有瘤胃瘘管的3头成年肉羊为试验动物,测定食叶草中4种常规营养成分在2、4、6、12、24、36、48 h时的瘤胃降解率和降解参数.结果表明:新鲜食叶草中初水分含量为91.12％,食叶草干物质(DM)中有机物(OM)含量达到96.99％,粗蛋白质(CP)、粗脂肪(EE)含量分别为31.43％和2.45％,中性洗涤纤维(NDF)、酸性洗涤纤维(ADF)含量分别为31.75％和25.45％,钙(Ca)、磷(P)含量分别为0.51％和0.40％.食叶草DM、CP、NDF、ADF 48 h的瘤胃降解...

This study aimed to investigate the nutritional value and ruminal degradation characteristics of protein grass in sheep,in order to provide a theoretical basis for its application in ruminant diets.Chemical analysis methods were conducted to determine the conventional nutritional component contents of protein grass.In addi-tion,the rumen degradation rate and degradation parameters at 2,4,6,12,24,36 and 48 h of 4 conventional nutritional components in protein grass were measured with 3 rumen-cannulated adult mutton sheep(n=3)u-sing nylon bag met...
