新疆生产建设兵团第七师124 团的畜牧业主要以发展养羊业为主,建成了以南非肉用美利奴羊罗米尼·希尔斯肉用羊养殖为主的种羊场,采用农区半放牧半舍饲方式进行规模化饲养.文章概述了该团绵羊品种现状、种质资源的利用情况和采取的改良措施,即应用胚胎移植、发情调控技术实行两年三胎,结合高效繁育配套技术,提高了品种繁育效率,加快了纯种繁育期限.
Research on efficient breeding technology in sheep for meat
The livestock production of the 124th Regiment of the Seventh Division of Xinjiang Production and Construction Corps mainly focuses on sheep farming,with an established breeding farm primarily raising South African meat-producing Merino sheep,known as Romney Marsh for meat production through a combination of semi-extensive and semi-intensive farming methods from local agricultural areas to achieve large-scale breeding.The article presents an overview of the current status of sheep breeds and the utilization of genetic resources within the regiment and proposes corresponding improvement measures which include the application of embryo transfer technology and estrus synchronization techniques to achieve three lambing cycles within two years.In addition,this paper suggests the way of utilizing high-efficiency breeding support technologies to enhance breeding efficiency and shorten the purification period of purebred breeding.
