摘  要：
以引进的无角陶赛特羊、波德代及本地滩羊与小尾寒羊及蒙古羊不同杂交组合的后代(杂交一代、杂交二代及杂交三代)为研究对象,采用随机抽样的方法,对已培育出的西北肉用绵羊新品种群的部分杂交组合生长发育性状,在不同月龄通过测定体重体尺指标进行研究,探讨了培育新品种最佳的杂交组合模式。结果表明,杂种三代生长发育速度快于杂种二代,杂种二代生长发育速度优于杂种一代;三种杂交组合改良小尾寒羊及蒙古羊的效果都好,尤其是高代或三元杂交的经济效应更为显著。因此,选择理想型的三代或二代杂种羊进行横交固定培育新品种的技术方案是可行的。

摘  要：
In this study, the introduced meat sheep of foreign Poll Dorset, Borderdale and the local Tan sheep in contrast to the local Small-tail han sheep and Mongolian sheep hybrid combinations of different generations (F1, F2 and F3), by random sampling methods that have been breeded for new population of mutton sheep in northwest of China with growth and development of hybrid combination of traits that were measured at different ages to determine their body indices in order to analyze the crossbred effect in contrast to Small-tail han sheep and Mongolian sheep, which probe into optimal hybrid combinations of pattern for new population of mutton sheep in northwest of China. The result shows that the major productive performances of the three-crossbreed are all superior to the corresponding second-crossbreed and the second-crossbreed are all superior to the corresponding first-crossbreed respectively, which three hybrid combinations of different generations indicates the marked crossbred effect, particularly the economic effect for high generation or ternary crossbred is most significant. Therefore, it is feasible to scheme of new breeding population of mutton sheep which crossing fixed was selected ideally the three-crossbreed or second-crossbreed.
