补饲添加剂提高牦牛产奶量试验

Feed Additive Experiment to Improve Milk Yield of Yaks

为的提高牦牛的产奶量,对麦洼牦牛(全奶和半奶)进行了为期6个月的补饲添加剂(矿物质十尿素)试验。结果表明,全奶牦牛和半奶牦牛试验组的挤奶量分别比对照组提高15.45和14.83%(P<0.01),尤其是试验后期更为显著。

Two experiments of providing feed additive to yak cow to improve milk yield were conducted with milking yak, which calved in this year, and semi—milking yak, which calved in the last year, for 6 and 5 months. The result showed that milk yield of treatment groups of milking yak and semimilking yak increased by 15.45 and 14.83% compared with each control groups respectively.
