摘要
新疆近交牛群体是利用1头本地母牛及其子代1头公牛为系祖,经过长期闭锁近交培育形成的近交系数很高的一个近交牛群体,是新疆维吾尔自治区的一个独特牛种质资源。为保护和合理利用这一宝贵遗传资源,在新疆塔城地区塔城市恰夏镇养殖户卢国昌牛场,新疆畜牧总站联合中国农业大学、新疆农业大学、石河子大学、塔城地区畜牧科技研究推广中心等单位开展了新疆近交牛群体实地调查和研讨。结果表明:该近交群体已克服近交衰退引起的生存力弱的问题,对当地恶劣的生存环境和粗放养殖条件能很好适应。并提出保护利用塔城近交牛群体的建议。
The Xinjiang inbred cattle group is an inbred cattle group with a high inbreeding coefficient formed by long-term closed inbreeding,using a native cow and its offspring and a bull as the line ancestor.It is a group of inbred cattle in Xinjiang Uygur Autonomous Region.And it is unique cattle germplasm resource.In order to protect and rationally use this precious genetic resource,at Lu Guochang cattle farm,a breeder in Qiaxia Town,Tacheng District,Xinjiang,Xinjiang Animal Husbandry General Station cooperate with China Agricultural University,Xinjiang Agricultural University,Shihezi University,and Tacheng Animal Husbandry Technology Research and Extension Center have carried out on-site investigations and discussions on inbred cattle in Xinjiang.The results show that this inbred group has overcome the problem of weak viability caused by inbreeding decline,and can adapt well to the harsh local living environment and extensive breeding conditions,and put forward suggestions for protecting and using Xinjiang inbred cattle.
