摘　　要：本研究对30头怀孕母牦牛妊娠后期153 d的"燕麦青干草+营养舔块"补饲试验,整个试验期内试验组与对照组(自然放牧)牦牛体重差异不显著(P>0.05),但所产犊牛初生重13.05 kg与11.50 kg的差异极显著(P<0.01)。The test of supplementary feeds using ＂green oat hay plus animal nutrition blocks＂ was carried out on thirty pregnant cows of late pregnancy（after 153 days）.The results indicated that the difference of weight between treated groups and control group were not significant（P〉0.05） during whole experiment period.But the difference of the birth weight of yak calves（13.05 kg and 11.50 kg） were very significant（P〈0.01）.
