摘要
对１９头健康牦母牛在发情期中阴道粘液的变化情况进行了研究，结果表明，在友情盛期，牦母牛阴道粘液ｐＨ值为７；１２±０．３１，阴道分泌物抹片镜检可见大量无核上皮细胞，少量有核上皮细胞，很少见白细胞，并有５２．６％牛只出现不同形状的粘液结晶；在发情末期，阴道粘液ｐＨ值为６．９７±０．２７，镜检可见上皮细胞减少，白细胞增多，粘液结晶出现率明显减少仅占３１．２％；受试１９头牦母牛中，受孕数１３头，受胎率为６８．４％，其中，１０头出现粘液结晶的发情牦母牛全部受孕（１００％），９头未发现粘液结晶的牛只仅受孕３头（３３．３％），二者差异极显著（Ｐ＜０．０１），由此看出，牦母牛在友情期中阴道粘液结晶的出现率与会胎率成正相关。该研究结果为准确判定牦母牛发情期，指导过时输精及提高杂交受胎率，提供了简便易行的方法和基础参考数据。
The study on changes of PH values ,crystals and cytology in vaginal mucus of 19healthy female yak in oestrus was carried out.The results showed that,in flourish of Yak′s oestrus,thepH value was 7.12±0.31 ,a large numberr of non-nucleated and a few nucleate epithelial cells of themucus were observed under the microscopo and the leueoeyte were rare,the vaginal mucus crystalswith various shapes were observed in 52.6%(10) experimental yak,in last stage of yak′s oestrus,thepH value of vaginal mucus was 6. 97±0. 27,with the increase of leucocyte,the epithelial cellsdecreased,the vaginal mucus crystals decreased obviously and were found only in 31.2%(5)experimental yak. 13 yak became pregnant in all 19 experimental yak and the conception rate was 68. 4%,in which all 10 yak with the emergence of vaginal mucus crystals became pregnant and only3 yak became.epregnant in 9 yak with no crystals,the difference was magnificent(p< 0. 01), thisresult showed that the einergence of vaginal mucus crystals of yak in oestrus was interrelated to theconception rate of yak positively.
