Abstract: To study the optimal process of superovulation and improve the efficiency of embryo transfer, one of the factors influencing effects of superovulation in Boer goat, methods of superovulation, times of superovulation, methods of insemination, season of superovulation and parity of donor were studied in this trial. The result showed that the different methods had a significant effect on superovulation (P<0.05). The mean number of viable embryos in second and the rate of viable embryos in first repeat superovulation were significantly more than that of donors without treatment (P<0.05). Methods of insemination, season of superovulation and parity of donor did not affect the results of superovulation significantly (P>0.05).
