子宫内输精技术在绵羊生产中的应用研究

Applied Research of Intrauterine Insemination Technology on Sheep Production

对绵羊腹腔镜子宫内输精技术的输精时间、输精部位进行了研究,并在实践应用中对该技术加以改进和完善,进一步验证了子宫内输精优点和输精的可操作性。试验结果表明：诱导发情的母羊在撤栓后54 h,同期发情母羊在撤栓后60 h,采用双侧子宫角深部输精,输精效果最好,受胎率可达60%～80%。

The time, the part and the effective number of sperm of laparoscopic intrauterine insemination technology were studied and this technique was perfected in the productive practice. The advantage and operability of intrauterine insemination have been validated. The results indicated it was better to insenminate 54 h after pessary removal for ewes of induced oestrus and 60 h after pessary removal for ewes of synchronized oestrus for bilateral uterine horn, the conception rate of ewes with frozen semen was 60-80.
