不同特征麦洼牦牛生产性能分析

Comparing the Production Performance between Maiwa Yaks with Different Coat Colors

针对各年龄段不同毛色外形特征的麦洼牦牛公母牛的体重、产奶量等生产性能进行对比分析。结果表明,弗洛型的体重高于粉嘴型,粉嘴型高于纯黑型,差异显著,初步判断弗洛型产肉性能高于麦洼牦牛;纯黑型的产奶性能最优,粉嘴型的其次,弗洛型的产奶性能最低,尤其是第三胎以后差异显著;粉嘴型其肉奶产量均比较均衡。

In this study, we compared the weight, milk production between Maiwa Yaks with different coat colors. The results showed the weights of Flo type are significant higher than the yaks with powder mouth, whose weights are significant higher than the pure black yaks. It infers that Flo type＇s meat performance is higher than any other tested yaks. On the contrary, taking the milk performance into account, the pure black yaks yielded highest milk while the flo type has the lowest milk production, especially after the third child.Generally, powder mouth yaks possessed a relative befitting meat and milk yield.
