摘 要:阿勒泰羊是新疆阿勒泰地区的本地优势品种,在以往肉羊养殖产业发展中扮演十分重要的角色。由于地区无序杂交、近亲杂交或者种间滥交,使阿勒泰羊的生产能力呈现逐渐下降趋势。通过引进优质肉羊进行经济杂交,能在短时间内实现对本地羊品种的产量,同时还能提高肉羊的养殖效益。该文主要论述阿勒泰羊与萨克斯肉羊经济杂交的必然性,并提出具体的杂交利用技术。Altay sheep is the dominant local breed of Altay prefecture in Xinjiang and has played an important role in the development of meat sheep breeding industry in the past.The productivity of Altay sheep has been declining due to regional disorder,inbreeding,or interspecific promiscuity.Through the introduction of high-quality mutton sheep for economic crossbreeding,the yield of local sheep varieties can be realized in a short time,and the breeding benefit of mutton sheep can be improved.This paper mainly discusses the necessity of economic crossbreeding between Altay sheep and sax sheep,and puts forward specific crossbreeding utilization technology.
