摘要
[目的]为了研究无角牦牛与有角牦牛的育肥效果,为无角牦牛的培育提供科学依据,[方法]本试验在青海大通种牛场开展了放牧补饲的育肥方式,并对其生长情况及育肥效果进行分析,[结果]通过146d的育肥,无角牦牛的总增重和平均日增重比有角牦牛的分别增加了1.78kg和12.2g。[结论]无角牦牛的育肥效果高于有角牦牛,若在完全舍饲条件下,将有助于无角牦牛发挥其遗传潜力。
[Objective]The aim of this work was to study the hornless yak and horned yak fattening effect,which will provide a scientific basis for the cultivation of hornless yaks.[Methods]This experiment were carried out grazing feeding fattening in Qinghai Datong cattle farm,and the growth and fattening effect were also analyzed.[Results]The results showed that compared to horny yak,the total weight gain and average daily gain of hornless yak increased by 1.78 kg and 12.2 g after 146 days,respectively.[Conclusions]Fattening effect of hornless yak was higher than the horned yak,and it would contribute to exerting genetic potential of hornless yaks under complete housing conditions.
