Laparoscopic endoscopic insemination is also called uterine horn insemination, which is mainly used in sheep farms of a certain scale for regular large-scale breeding of ewes. One time of ram semen collection can inseminate 10-20 estrus ewes. Through the synchronized estrus technology, the ewes can be in estrus regularly, inseminated regularly, and give birth to lambs regularly, which is beneficial to the feeding and management of lambs.
