摘要
利用日增重对生长牦牛在自由采食不同日粮时的能量代谢进行了估测。结果表明,当精料:小麦秸为28:72及48:52时,生长牦牛对日粮能量的代谢率分别为0.470±0.044和0.478±0.031,差异不显著(P>0.2)。
This experiment was carried out to estimate the energy metabolism from the formula according to daily gain(AG). The result showed that the metabolizability(q) of ration is 0.470±0.044 or 0.478±0.031 when animals are reared by two rations in which concentrate: wheat straw is 28:72 or 48: 52 respectively. No notable difference(p>0.2) is observed.
