摘要: 本文报道了以7只1-2岁莎能山羊(♂)×成都麻羊(♀)杂交山羊为试验动物,饲喂三个水平的牛鞭草(Hemarthriacompressa)混合日粮,进行产气法(HFT技术)和全收粪法测定有机物消化率的比较试验。结果表明,三个日粮全收粪法有机物消化率分别为57.53±1.80%、54.12±1.02%和49.20±1.61%;产气法测定的相应值为57.40±1.71%、53.26±1.20%和49.41±1.19%。两种方法测定结果经t验P>0.05,变异系数平均为2.76%和2.55%,表明产气法测定的结果是可靠的。

Abstract: It is reported that the organic matter digestibilities (OMD) of three different (OMD) of three different Hemarthria compressa mixturefeeds were comparatively measured by IN VIVO method and Hohenheim Forage Quality Test (IN VITRO) on 7 hybrid goats (Sannen×Chengdu Ma goat).The results showed that OMDs of 3 feeds by IN VIVO were 57.53±1.80%, 54.12±1.002% and 49.20±1.61%, by HFT were 57.40±1.71%.53.26±1.20% and 49.41±1.19% respectively.The mean CV 2.76% and 2.55% of OMDs tested by the two methods illustrated that HFT was reliable, (P>0.05).
