羊腹腔镜子宫角人工输精技术

采取人工授精技术可极大提高羊的生产性能，增加优秀个体所占比例，加快选育速度；可有效利用具有最优遗传性状的公羊，快捷而有效的增加优秀种羊的推广面与覆盖度；减少种公羊饲养管理费用与死亡率；防止因交配而感染疾病，提高母羊的受胎率。目前，研究人员在新鲜精液的基础上，又开发出了冷冻精液输精，冷冻精液可减少养殖场种公羊的饲养数量，控制养殖场的公母比例，大幅降低养殖成本，提高养殖场的经济效益。作者介绍了阴道输精技术及腹腔镜子宫角输精2种常用输精技术，同时简述了其优缺点；阐述了腹腔镜子宫角输精技术的各项操作流程及操作过程中的注意事项和术后护理等，旨在为腹腔镜子宫角输精技术提供理论依据及在实践过程中提供技术支持。

Research Progress on Laparoscopy Artificial Insemination of Uterine Horn in Sheep

The adoption of artificial insemination technology can greatly improve the production performance of sheep,increase the proportion of excellent individuals and speed up the breeding,and can make effective use of the ram with the best genetic traits to increase the extension surface and coverage of excellent breeding sheep quickly and effectively.It can greatly reduce the breeding cost and mortality of breeding rams,prevent diseases infected by mating,and improve the conception rate of ewes.On the basis of fresh semen,frozen semen has been developed which can reduce the number of rams and the feeding cost of breeding farms,and control the ratio of males to females.The author briefly introduced the operation of two kinds of artificial insemination in sheep (abdominal mirror uterine horn insemination and vagina artificial insemination),and described the advantages and disadvantages of the two techniques.This paper expounds the operation flow,matters needing attention and postoperative nursing of abdominal mirror uterine horn insemination,in order to provide theoretical basis and technical support for abdominal mirror uterine horn insemination.
