摘　　要：采用放置CIDR结合注射PMSG方法分别在春季和冬季对154只受体山羊进行同期发情处理,并在发情后第7天进行胚胎移植.结果表明:处理羊只春冬两季的同期发情率分别为90.54%和75.00%;有效发情率分别为81.08%和60.00%;妊娠率分别为61.67%和45.83%;产羔率分别为75.00%和54.17%,差异均极具有统计学意义(p<0.01);春季和冬季发情羊排卵并形成功能黄体的比率分别为89.55%和80.00%,差异不具有统计学意义(p>0.05).说明季节对山羊同期发情和胚胎植移效果有一定的影响,但对已发情的羊只形成功能黄体比率影响不明显.In spring and winter,154 receptor goats were disposed by synchronization of estrus with progesterone-containing intra-vaginal sponges（CIDR）plus PMSG method,and embryo transfer was performed on the seventh day after estrus.The results showed as follows：synchronized estrus rate in spring and winter were90.54% and 75.00%,respectively（P〈0.01）.And the rate of effective estrus were 81.08% and 60.00%,respectively（P〈0.01）.And the rate of pregnancy were 61.67% and 45.83%,respectively（P〈0.01）.And the rate of lambing were 75.00% and 54.17%,respectively（P〈0.01）.The ratio of estrus goats ovulation and formation of functional corpus luteum in spring and winter were 89.55% and 80%（P〈0.05）.Thus indicating the season has certain influence on the goat estrous synchronization and embryo transfer effect,but the estrous goats form a functional corpus luteum ratio was not affected.
