摘　　要：选取80只母山羊,随机分为对照组和2个试验组,对照组为经产母山羊子宫颈输精;试验Ⅰ组为初产母山羊腹腔镜输精;试验Ⅱ组为经产母山羊腹腔镜输精,比较腹腔镜输精技术对山羊繁殖性能的影响。结果表明,经产母山羊腹腔镜输精后的受胎率为76.67%,子宫颈输精后的受胎率为60.00%,差异不显著;经产母山羊腹腔镜输精后的产羔率和成活率分别为2.22只/母羊、82.35%,与子宫颈输精的产羔率和成活率(分别为1.83只/母羊和75.77%)差异不显著;初产母山羊腹腔镜输精后的产羔率为1.46只/母羊,显著低于经产母山羊腹腔镜输精的产羔率(2.22只/母羊)。说明腹腔镜输精技术对经产母山羊的繁殖性能有一定的积极效果,但在山羊生产中广泛推广应用仍需加强研究。To study the influence of laparoscopic artificial insemination on reproductive performance of goat, 80 healthy ewes were randomly divided into control group and two experimental groups. In the control group, cervical insemination was used for multiparous ewe; in the experiment group Ⅰ, laparoscopic artificial insemination was used in primiparous ewe; and the experiment group Ⅱ, laparoscopic artificial insemination was used in multiparous ewe. The results showed as follows, the conception rate of laparoscopic artificial insemination and cervical insemination in multiparous ewe and the control group was 76.67% and 60.00% , respectively; and the difference was not significant. The lambing rate and survival rate of laparoscopic artificial insemination in multiparous ewe was 2.22 goats/ewes and 82.35% , respectively, which showed no difference to the cervical insemination for multiparous ewe（1.83 goats/ewes and 75.77% ）. The lambing rate of laparoscopic artificial insemination of primiparous ewe was dramatically decreased compared with the laparoscopic artificial insemination of multiparous ewe.The effective of laparoscopic artificial insemination was positive for the reproductive performance of multiparous ewe, but it needed further research for popularization and application in goat production.
