摘　　要：本研究从2017年4月开始,在西藏拉萨市当雄县郭庆村牦牛养殖合作社将40头2岁试验组牦牛以半舍饲方式补饲养殖、10头对照组牦牛以传统放牧养殖,进行了为期1年的对照试验。结果表明,补饲可显著提高牦牛越冬时的保膘效果。根据市场规律,屠宰旺季即当年10月,补饲牛相对自由放牧牛仅平均增重15.4kg,带来平均每头616元的额外收入。本研究表明,牦牛半舍饲补饲可缓解冷季掉膘,减少其带来的损失,并增强牦牛越冬能力,从而增加牧民收入。This study began in April 2017.In the yak breeding cooperative of Guoqing Village,Dangxiong County,Lhasa City,Tibet,a one-year controlled trial on the 2-year-old yaks was conducted.In the trial,40 yaks of experimental group were fed by supplemented half-feeding,and 10 yaks of control group were fed by traditional free-grazing.The results showed that supplemental feeding could significantly improve the preservation effect of yak during winter.According to the market rules,in the slaughter season(October of that year)the supplemental half-feeding yak only gained more15.4 kg on weight by average,compared with the free-grazing,resulting in an average income of 616 yuan per head.This study showed that supplemental half-feeding could alleviate the losing weight in cold season,reduce the loss it caused,and enhance the survival ability of yak,thus increase the herders′ income.
