摘　　要：采用引进的杜泊羊冷冻胚胎 ,以云南当地绵羊为受体进行胚胎移植。同期发情处理了 15 8只受体羊 ,同期发情率为 82 91% ;对 10 2只进行了胚胎移植 ,实际移植率为 77 86 % ,3个情期内移植妊娠率达74 5 % ;出生 6 8只 ,产羔率达 6 6 7%。分析表明 ,胚胎发育阶段及级别、卵巢黄体情况、以及胚胎移植技术熟练程度直接影响胚胎移植成功率 ;此外 ,受体羊的处理程序及移植后的饲养管理、移植时机的把握、移植季节以及胚胎冷冻及解冻方法也会影响杜泊羊移植妊娠率 ,进而影响产羔率。Yunnan local recipient ewes were synchronized,and 102 imported Dorper sheep embryos were thawed and transferred.The rates of synchronization and embryo transfer were 82.91% and 77.86%,respectively.Conception rate in the first three estrus cycles and birth rate was 74.5% and 66.7%,respectively.The results suggeste that the effect factors of frozen embryo transfer in Dorper sheep include stage and class of embryo and corpus luteum.Besides,personnel techniques of transferring affect conception and birth rate directly.Besides,protocol of transfer,recipient breeding and management,timing and reason of embryo transfer are important to Doper embryo transfer.
