摘　　要：为了研究安徽省野生芭茅草在肉牛瘤胃中的降解规律,在安徽太湖地区开展试验,测定了芭茅草部分营养成分的含量,并采用尼龙袋法测定了芭茅草的干物质(DM)、有机物(OM)、粗蛋白(CP)、中性洗涤纤维(NDF)和酸性洗涤纤维(ADF)在瘤胃6、12、24、36、48、72 h的动态降解率。结果表明,芭茅草DM、OM、CP、NDF和ADF的含量(干基)分别为98.15%、93.62%、6.51%、68.07%和38.93%,有效降解率分别为36.26%、35.37%、43.34%、29.19%和25.93%,芭茅草可作为肉牛优良粗饲料。In order to study the degradation law of wild Miscanthus floridulus in the rumen of beef cattle in Anhui Province,this experiment was carried out in Taihu of Anhui Province.The content of some nutrients in M.floridulus were determined.The dynamic degradation rates of dry matter(DM),organic matter(OM),crude protein(CP),neutral detergent fiber(NDF)and acid detergent fiber(ADF)in rumen at 6,12,24,36,48 and 72 h were determined by using nylon bag method.The results showed that the content of DM,OM,CP,NDF and ADF(dry matter basis)were 98.15%,93.62%,6.51%,68.07%and 38.93%respectively.And the effective degradation rates were 36.26%,35.37%,43.34%,29.19%and 25.93%respectively.
