摘 要:杜泊羊(Dorper sheep)和萨福克羊(Suffolk sheep)是国外著名的肉用绵羊品种,具有生长发育快、产肉性能高、肉质优良等优点,是生产优质肉羊的终端父本品种,自引进我国后,已在全国各地被广泛推广应用,助推了我国肉羊产业的发展。利用杜泊羊和萨福克羊与国内本地绵羊杂交生产的F1代羔羊不仅初生个体大、生长速度快,而且胴体重、屠宰率及净肉率等产肉性能也明显提高,优于本地绵羊品种,对本地绵羊品种具有较好的改良作用,杂种优势明显。笔者对以杜泊羊和萨福克羊分别作为父本,与国内不同肉用品种绵羊进行二元杂交后F1代的生长发育情况、屠宰性能及杂交的产羔性能进行归纳、总结和分析,以期为利用杜泊羊和萨福克羊改良我国商品肉羊品种的研究提供理论依据。Dorper sheep and Suffolk sheep are famous foreign meat sheep breeds.With rapid growth and development,high meat production performance,excellent meat quality and other advantages,they become the end product of high-quality meat sheep.Since their introduction into China,they had been widely promoted and applied throughout the country,which has boosted the development of China's meat sheep industry.The F1 generation lambs produced by crossbreeding Doper sheep and Suffolk sheep with domestic mutton sheep not only have large newborn individuals and fast growth rate,but also have significantly improved carcass weight,slaughter rate,net meat rate and other meat production performance,which is superior to local sheep breeds.It has better improvement effect on local sheep breeds,and has obvious heterosis.The growth and development,slaughtering performance and lambing performance of Duper sheep and Suffolk sheep and domestic mutton binary hybrid offspring were summarized and analyzed in this paper,in order to provide a theoretical basis for the study of improving commercial meat sheep by using Duper sheep and Suffolk sheep in China.
