| 摘 要： | 对青南地区和环湖地区的西杂和荷杂公牛与牦牛杂交所生犏牛的生长发育进行了测定,并与同龄牦牛进行比较,结果表明:初生、6月龄、18月龄、30月龄荷杂犏和西杂犏所有体尺体重指标均极显著的高于对照组牦牛(P<0.01);初生、6月龄、18月龄荷杂犏和西杂犏体重均无显著差异(P>0.05);犏牛初生体重大于牦牛,生长发育快,杂种优势明显,至18月龄,两种犏牛平均体重比牦牛高51.05 kg;到30月龄时,两种犏牛平均体重比牦牛高90.0 kg,比牦牛体重高出51.50%。

| Abstract: | The growth and development of two kinds of hybrid cattle recrossed with yak(Holstein or Simmental♂×Yellow Cattle♀= Hybrid Male♂×yak♀) in south Qinghai and Surrounding Qinghai Lake Region was determined,and the parameters were compared with that of yak at the same age.The results show that: 1) the body size and body weight of the hybrid show a significant difference with that of yak(P<0.01);2) the body weight of newborn,six month old,18 month old show no significant different(P>0.05)between two kinds o... |
