Abstract: The matching assembly of embryo transfer technology on Alpas white cashmere goats has been explored to accelerate the application and popularization of embryo transfer in sheep husbandry by applying technologies such as donor selection, estrus synchronization, superovulation, surgical egg collection, estrus synchronization processing on receptor sheep and surgery transplantion. The selection standard of donor sheep and application experience in sponge-boh method of estrus synchronization on donor sheep were summarized. The estrus rate of the donor reached to 100 %1 the utilization rate was 98.33 % and 10.2 embryoes on average were available in the 13.9 embryoes on average reclaimed by the fallopian tube method. The estrus rate of receptor was 81.66 %, the fresh embryo transfer pregnancy rate was 77.92 %, the lambing rate was 105.78 % and the reproductive rate was 79.28 %. The conclusion implied that it was suitable to use the matching technology of embryo transfer on goats for the production situation of the breeding sheep improvement on sheep husbandry at present, and the technology was more mature and stable and could be applied and popularized widely in the rural and pastoral areas.
