摘要:

杜泊羊是原产于南非的世界性著名肉用种羊,是优良的肉羊杂交生产终端父本,自引入中国以后,已分布于多个省(自治区、直辖市),对推动中国商品肉羊生产发挥了重要作用。作者通过对杜泊羊生长发育快、产肉性能好等种质特征的介绍,以及对中国不同地区引入杜泊羊后,分别与本地品种绵羊杂交后的F1代生长发育、产肉性能进行比较分析,发现杜泊羊作为父本与本地绵羊杂交后的F1代均表现出较强的杂种优势,可以作为中国培育肉羊新品种及杂交改良的优异父本品种。

Abstract:

Dorper sheep is native to South Africa, it is one of the world famous mutton sheep breeds, it is a good terminal male parent of mutton sheep hybrid production, after be introduced into China, it has been distributed in many provinces (municipality, municipalities directly under the central government), and has played an important role in promote the commercial mutton sheep production in China. In this paper, through introducing the rapid growth and development of Dorper sheep, good meat performance of germplasm characteristics, and by introducing Dorper sheep at different regions in China,the first filial generation of hybrid with local sheep varieties respectively compared with local sheep in growth and development, meat performance, we found that the first filial generation of Dorper sheep as male parent hybrid with local sheep all showed strong heterosis, and could be used as excellent male parent varieties of cultivate the new mutton sheep varieties and hybridization and improvement in China.

Key words: Dorper sheep; hybridization; growth and development; meat performance
