摘　　要：在海拔高度３４００～３７００ｍ的冬春草地上，修建牦犊牛暖棚舍，制作氨化秸秆，于１９９４年１２月到１９９５年２月对４６头１／４野血牦犊牛进行冷季夜间暖棚舍保温和补饲试验。试验群犊牛平均每天每头补饲氨化秸秆０．５８３ｋｇ。试验结果：经７６天试验，试验群犊牛体重平均增重６．４ｋｇ，日增重８４．７ｇ，对照群犊牛平均增重－３．５ｋｇ，日增重－４６．２ｇ，试验群犊牛比对照群多增重９．９ｋｇ，日增重多１３０．９ｇ，经ｔ检验，两组间日增重差异极显著（Ｐ＜０．０１）。每头可获经济效益３１．６１元。calves of 1/4 wild yak were used in a 76 day trial to observe the effect ofsupplementary feeding and greenhouse on growth of the animals from Dec of 1994 to Feb of1995 at 3400～3700 m altitude. All animals were grazed in day and given 0. 583kg ammoniat-ed barley straw in night. The average daily gain of experiment group was significently higher(84. 7g)than that of the control group(-46. 2g). The net profit for each animal is 31. 61Yuan RMB.
