摘要
为了探讨补饲对牦牛越冬的积极作用,在冷季对不同生长发育阶段(2岁、3岁及5岁以上)牦牛进行了放牧加补饲的育肥试验。结果表明:不同生长发育阶段的牦牛其试验组日增重极显著高于对照组(P<0.01),经济效益明显提高。
In order to investigate the fattening effect of supplementary feeding on yak in winter,the fattening experiment on the yak at the age of 2 years, 3 years and 5 years plus were carried out. The results showed that the yak daily weight gains in different ages were significantly higher than those of the control group in the cold season, and the economic benefits rised apparently.
