| 摘 要： | 试验选用3头装有永久性瘤胃瘘管的4岁1/2野血大通牦牛作为试验动物，同时运用尼龙袋法和体外产气法评定青海当地燕麦青干草营养价值。结果表明，燕麦青干草中粗蛋白质含量为7.17%，粗脂肪含量为2.23%，中性洗涤纤维含量为54.86%，酸性洗涤纤维含量为29.15%；72 h干物质降解率产气法测定值为87%，尼龙袋法测定值为80.56%；估测得出燕麦青干草有机物质消化率89.30%，代谢能为13.99(MJ/kg DM)。用尼龙袋法测定的燕麦青干草的干物质降解率在4、6、8 h均略高于体外产气法测定值， 12、24、36、48、72 h测定的干物质降解率均略低于产气法测定值，但差异均不显著（P＞0.05）。对2种方法测定值作相关性分析，得出r＝0.98，表明这2种方法所测定出来的数据正相关。

| Abstract: | 3 yaks,4 years old,with permanent rumen fistula,which had 1/2 wild blood,were chosen to assess nutritional value of Qinghai local oat hay with in vitro gas production method and nylon bags method.The result showed that in oat hay,the content of CP was 7.17%,EE was 2.23%,NDF was 54.86%,ADF was 29.15%;dry matter digestibility of oat hay in 72 h which was measured by in vitro gas production method is 87%,by nylon bags method was 80.56%.We estimated that the digestibility of ODM was 89.30%,ME was 13.99 MJ/kg DM... |
