对150头母牦牛开展了牦牛细管冻精人工授精试验。试验结果显示：试验母牛在第一情期发情率63.33%,第二情期发情率50.00%,第一情期与第二情期发情差异性不显著﹙P〉0.05﹚。第一情期受胎率为53.95%,第二情期受胎率88.46%,第一情期与第二情期受胎率之间差异极显著﹙P〈0.01﹚;试验组母牛平均受胎率62.75%与对照组80.00%受胎率之间无差异（P〉0.05）。

150 female yaks were inseminated with frozen semen. The results showed that the estrus rate in first, second phase were 63.33% and 50.00% respectively. There is no significant difference between first phase and second phase （ P 〉 0.05 ）. The fertility rate in first, second phase were 53.95% and 88.46% respectively . There is significant difference between first phase and second phase （ P 〈 0.01 ）. There is no significant difference in fertility rate between 62.75% of experimental aroup and 80.0% of control group（P 〉0.05 ）.
