Abstract: 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 groupⅠ, 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.
