摘要
随机从牛场中抽取试验动物 1 .5岁杂交一代公牛 3头和母牛 3头 ,1 .5岁左右本地母牛 3头 ,三月龄左右的杂交一代黄牛和本地黄牛各 3头 ,不分公母 .其中杂交一代为利木赞冷冻细管精液与本地母牛通过人工授精配种后的后代 ,对它们进行体质测量和估重 ,结果表明 :杂交一代在体质状况方面明显优于本地黄牛 .体高、腰高、坐骨高均比本地黄牛高 ,胸围明显比本地黄牛大 ,体斜长也比本地黄牛长 ,管围也明显比本地黄牛大 .通过公式 :活重 =[(胸围 ) 2 ×体斜长 ]/ 1 0 80 0 ,对体重进行计算比较 ,杂交一代牛的体重明显重于本地黄牛 。
We pick out ox from the field as experiment animals. There are six hybrids of first generations(three bull and three cow )and three native ox which are the age about one and a half years old . Also there are three hybrids of first generations and three native ox which are the age about three months old (not consider the sex ). The first generation of hybrid ox are bred by the freezing slender pipe seminal fluid of Li Mu Zan and native ox.We measured their physique build and reckoned their weight . The results show that the first generation of hybrid ox are higher than the native ox in the height of body ,waist and sciatic ,and are superior to the native ox in the round of chest and the length of the body .We can get the weight through heave=(chest measurement)~2 × the length of body/10 800.We can get the result that the weight of the first generation heavier than the native ox .It is consistent with former results of research.
