摘要：超數(shù)排卵和胚胎移植技術(shù)是擴繁優(yōu)良羊只的高新技術(shù)。該研究對2只供體和20只受體柴達木絨山羊母羊經(jīng)過同期發(fā)情和超數(shù)排卵處理，進行胚胎移植。結(jié)果表明，20只受體羊同期發(fā)情率達70.00%，供體羊產(chǎn)生12枚黃體，移植鮮胚9只羊，妊娠率達33.33%，產(chǎn)羔率達100.00%，羔羊成活率達100.00%。

Abstract： Superovulation and embryo transfer technology are high-tech for propagation excellent sheep. After 2 donor and 20 receptor chaidamu cashmere goat goats were treated for synchronization of estrus and superovulation， embryo transfer was carried out. The results showed that 20 the rate for synchronization of estrus among the 20 receptor goats was up to 70.00%； donors goat produced 12 pieces of corpus luteum； 9 goats were transplanted fresh embryo successfully； fecundation rate was 33.33%； lambing rate was 100.00%； and lamb survival rate was 100.00%.

Key words： Chaidamu cashmere goat； synchronization of estrus； superovulation； embryo transfer
