摘　　要：采用睾丸减数分裂分析方法，对犏牛的精子发生受阻情况进行研究，并讨论了其受阻原因．结果表明，犏牛精子发生存在各个时期的生殖细胞，但从精母细胞开始以后逐级受阻，其精子生成效率比牦牛及普通牛分别低１３～１５个百分点和１７～１９个百分点，仅为０．０９％With meiotic chromosome sample of testis,the prevention of spermatogenesis in Pien Niu is observed and analysed.It is found that spermatogenesis exist in all stages of spermatogenic cells,but the spermatogensis is gradually prevented from primary spermatocyte to spermatial.The spermatogenic efficiency is only 0.09%,which is 13～15% lower than that of yak and 17～19% lower than that of cattle.
