绵羊腹腔镜人工授精技术在哈萨克羊上应用效果研究

Study on the Effect of Sheep Laparoscopic Artificial Insemination on Kazae Sheep

在哈萨克羊肉用新品系培育过程中,通过利用绵羊腹腔镜输精配种技术开展特克赛尔羊与哈萨克羊杂交选配试验,以期探究绵羊腹腔镜输精配种技术在哈萨克羊上的应用效果,为今后哈萨克羊肉用新品系培育和绵羊育种提供参考。本试验共同期发情处理哈萨克羊母羊195只,总发情率94%,完成腹腔镜输精配种179只,其中冻精配种100只,鲜精配种79只,平均怀胎率达到82%。结果表明:利用绵羊腹腔镜人工授精技术,在哈萨克羊繁育和品种改良上使用冻精和鲜精配种均具有较好的效果,可进行广泛推广。

In order to explore the application effect of sheep laparoscopic insemination onKazake sheep,the crossbreeding test of Texel mutton sheep and Kazake sheep was carried out by using sheep laparoscopic insemination technology in the breeding process of Kazake mutton sheep,aiming atproviding reference for the breeding of Kazakemutton sheep and sheep breeding in the future.In this experiment,195 Kazake ewes were oestrus in the same period,the total oestrus rate was 94%,179 of them were inseminated by laparoscope,100 of them were inseminated by frozen semen,79 of them were inseminated by fresh semen,the average pregnancy rate was 82%.The results showed that the application of frozen semen and fresh semen in the breeding and breed improvement of Kazake sheep had a good effect and could be widely used.
