摘　　要：对青海高寒牧区犏牛挤乳量及乳成分进行了分析,并与同等饲养条件下的牦牛进行了比较。结果表明:1)不同地区犏牛挤乳量差异不显著(P>0.05);2)不同的产乳阶段两个地区犏牛挤乳量的变化趋势相同;3)犏牛挤乳量极显著高于牦牛挤乳量(P<0.01);4)犏牛乳脂与干物质低于对照组牦牛的含量,其它成份无显著差异。The milk yields and milk contents of pianniu were determined and the results were compared with that of yak under same feeding condition. It is concluded that： 1. There is no significant difference in milk yield of pianniu in different areas （ P〉0.05） ; 2. The trend of milk yield of pianniu in two different areas during different stages are similar; 3. The milk yield of pianniu is significantly higher than that of yak （ P〉0.05） ; 4. Fat and dry matter content of pianniu is lower than that of yak, and other contents show no significant difference among two groups.
