摘　　要：[目的]本研究为探讨不同方案诱导牦牛发情效果。[方法]选择放牧的母牦牛60头为试验牛。分2组,每组30头进行试验。其中试验1组带犊母牦牛12头,不带犊母牦牛18头,采用方案Ⅰ;试验2组带犊母牦牛14头,不带犊母牦牛16头,用方案Ⅱ处理。第一针注射黄体酮注射液,以治疗为目的,间隔10天肌注PG,第二天注射血促性素;结果第1组用方案Ⅰ处理后带犊、不带犊母牦牛发情率分别为42%(5/12)、56%(10/18),受胎率分别为60%、80%;第2组用方案Ⅱ处理后带犊、不带犊母牦牛发情率分别为86%(12/14)、100%(16/16),受胎率分别为65%、81%。[结果]表明,通过对牦牛进行冷季补饲,诱导发情及同期发情处理,使93%的母牦牛发情。[结论]方案Ⅱ是较为理想的同期发情处理方案。[Objective]In this study, we explored the effects of different schemes on yak oestrus induction. [Method]A total of sixty grazing female yaks were selected as test cattle. We divided them into two groups, each group had 30. Among them, 12 mother yaks with their baby and oher 18 mother yak without baby determined as Experiment 1, treated with scheme I ; 14 mother yaks with their baby and other 16 female yak without baby determined as Experiment 2, treated with scheme 11. The first needle injection of progesterone injection, treat for the purpose, every 10 days, inject PG in intramuscular, the next day inject blood-promoting sex hormone; We found that the rate of estrus was 42% （5/12）, 56% （10/18）, respectively; the conception rate was 60% and 80% , respectively, which was treated with group I ; the rate of estrus was 86% （12/14）and 100% （） 16/16）, respectively;the conception rate was 65% and 81%, repectively, which was treated with group Ⅱ [Result]Through this experiment,we could find that cold season feeding, induced estrus and synchronous estrus could make the 93% of the female yak estrus. [Conclusion]Scheme II was the ideal solution for oestrus synchronization.
