[ Method] Two FSH dosages （240 and 300 I U）, two seasons （April- June and October- December）, and two treatment frequencies （one or two times） were used to induce super-ovulation in goats. [ Result] Both average ovulation point and number of transferable embryos were significantly different between the goats given 240 IU FSH and those given 300 lU FSH （average ovulation point, 10.12 vs 15.55; number of transferable embryos, 8.82 vs 13.15） at the 0.05 level. Both average ovulation point and number of transferable embryos were also significantly different between April -June and October- December （ average ovulation point, 9.05 vs 15.55; number of transferable embryos, 7.05 vs 13.15） at the 0.05 level. Super-ovulation effect was not significantly different between the two treatment frequencies. [ Conduslonl The FSH dosages and seasons have significant impact on super-ovu- lation, but repeat super-ovulation does not have the same impact.展开更多
