| 摘 要： | 本试验利用１６０头繁殖力正常的黄牛研究体外和体内解冻西门塔尔牛精液的授精效果。试验组８０头黄牛用从液氮罐中取出的细管直接配种，对照组用常规的体外解冻方法输精。结果表明，试验组所配的８０头黄牛有６０头妊娠，第一情期受胎率为７５％，比对照组提高１６．３％，因此利用体内解冻法可大幅度提高黄牛受胎率，值得大力推广。

| Abstract: | One hundred and sixty yellow cattle with normal reproductivity were used to study the insemination results of thawing semen in vivo and in vitro. 80 cattle was inseminated with semen straw from liquid nitrogen jar, the other 80 cattle in control group was inseminated by general semen thawing method. The result showed that the pregnancy rate in first estrous cycle of treatment group was 75%, and increased by 16.3% compared with control group, the in vivo thawing method could increase pregnancy rate of yellow cattle and worthy of large scale extension. |
