6月龄德本F_1和蓝本F_1牛生长发育性能研究

Study on the Development Performance of 6 Months DF_1 and BF_1 Crossbred

本研究对德国黄牛和比利时蓝牛与本地牛的杂交改良效果进行了测定。在粗放饲养管理条件下,6月龄德本F1和蓝本F1的生长发育性能比同龄本地牛均有显著提高。6月龄公牛的体重德本F1为177.45kg、蓝本F1为118.26kg,比本地牛的113.50kg提高56.46%(P<0.01)和4.52%(P>0.05);6月龄母牛的体重德本F1为156.81kg、蓝本F1为108.86kg,比本地牛的97.57kg分别提高60.77%(P<0.01)和11.49%(P>0.05)。

This paper had studied the performance that the native yellow cattle was improved by Gelbvich and Belgian Blue using frozen wheatstraw semen which was bought from the beef engineering center of Henan province in 2003 to 2006. And showed that the 6 months development performance of F1 crossbred of Gelbvieh or Belgian Blue were higher than the native＇s. The male body weight of F1 crossbred of Gelbvich was 177.45 kg,and the F1 crossbred of Belgian Blue＇s was 118.26 kg,and the native＇s was 113.50 kg. Simultaneously those females body weight were 156.81 kg and 108.86 kg and 97.57 kg resp.
