利木赞牛生态适应性及其与鲁西黄牛的杂交效果

Study on the Ecological Adaptability and Hybriding Superiority of Limousin Cattle

文通过对利木赞种牛在鲁西北地区的生态适应性观察及其与兽西黄牛的杂交效果分析，认为（１）利木赞种牛在鲁西北地区适应性良好；（２）用利木赞种牛改良鲁西黄牛，其杂交后代在生长速度和体尺指标方面明显优于鲁西黄牛（ｐ＜０．０１）。

The ecological adaptability of France Limousin cattle in the North western Shandong was observed and its hybriding superiority with local Luxi cattle warealso analysed in this paper. The results show that show that:(1)The ecological adaptability of Limousin cattle is better;(2)Improving Luxi cattle by means of Limousin cattle,the hy-briding superiority of later generation is very significant(P<0.01).
