西夏本三元杂交牛生长发育研究

Growth and Development Study of Hybrids of Simmental, Charolais and Yubei Yellow Cattle

测定、分析了西夏本三元杂交牛(公41头、母35头)、西黄F_1(公34头、母34头)和豫北黄牛(公34头、母38头)初生-24月龄体尺、体重生长发育,结果表明,西夏本杂种牛生长发育快,各月龄体尺、体重显著大于豫北黄牛,比西黄F_1也有明显提高。利用三元杂交进行肉牛生产是一条有效途径。

The growth and development indicators including the body size and weight from birth to 24 month old of hybrids of Simmental×Charolais×Yubei yellow cattle(SCY) (bulls 41, cows 35), F_1 genera- tion of Simmental×Yubei yellow cattle(SY) (bulls 34, cows 34) and Yubei yellow cattle(bulls 34,cows 38) were measured in this study. The results showed that the development and growth of the hy-brids of SCY were significantly more than that of SY F_1 and Yubei yellow cattle for the body size andweight in every month. It is concluded that three breeds hybridization is an effective way of beef produc-tion.
