摘　　要：目的本试验对小型猪进行超数排卵和早期胚胎回收技术进行试验研究。研究结果如下:PG+PMSG+HCG法对断奶母猪的同期发情率达100%,优于其对非哺乳期空怀母猪的72.73%的同期发情率,但二者平均排卵数显著性差异(P<0.05);屠宰冲胚和手术法冲胚,胚胎回收率分别为84.29%和76.92%,回收率差异显著(P<0.05),但头均回收胚数无显著性差异(P>0.05)。Miniture pigs were used for superovulation and the recovery of early embryo. The results of this paper were： the rate of synchronization of PG ＋ PMSG ＋ HCG on weaning pig was 100%, while the rate Of non- weaning pig was only 72.73, but there appearanced obviously distance on average ovulation number（ P 〈 0.05）; the recovery of early embryo of slaughter and surgery were 84.29 % and 76.92 % （ P 〈 0.05 ）, but no obviously distance on the number of recovery embryo（ P 〉 0. 05 ）.
