  • 158 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.

Effect Factors of Frozen Embryo Transfer in Dorper Sheep

Abstract: 158 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.
