Abstract: 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.
