摘要
PMSG was used to study the follicular development and ovulation regularity of the sows.The results showed that the earlier copulation caused better ovulation effect after sows were injected PMSG,and the ovulation time of estrous sows centralized 12～63.5 h after accepting copulation.The observation of early embryos morphology showed that the embryos in the oviduct were in 2～4 cell stage,when entered womb,they were in 4～8 cell stage during 51～59.5 h and all of them entered womb during 71～83.5 h after the sows accepted copulation.
