摘要: 通过对阿尔巴斯白绒山羊供体选择、同期发情、超数排卵、手术采卵、受体羊同期发情处理、手术移植等技术应用,探索了规模化阿尔巴斯白绒山羊胚胎移植技术的组装配套,以加快胚胎移植在养羊业生产中的推广与应用。总结了供体羊选择标准、供体羊同期发情海绵栓法应用经验。供体发情率达100%、利用率为98.33%、输卵管法平均回收胚胎13.9枚、平均可用胚胎10.2枚:受体发情率81.66%、鲜胚移植受胎率77.92%、产羔率105.78%、繁殖率79.28%。结果表明,使用配套技术进行绒山羊胚胎移植较适合目前养羊业种羊改良的生产实际,技术较成熟、稳定,可在农村牧区广泛推广应用。

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.
