摘　　要：本试验通过不同补饲水平对28头3岁麦洼牦牛150d育肥效果测定,补饲组18头全期平均总增重67.73kg,平均日增重451.67g,相对增重率47%;高水平补饲的A组头平均增重比不补饲D组高34.5kg,日增重高230g,两项指标比对照组相对提高近70%。试验表明,在高寒牧区,暖季对牦牛进行适量补饲,能提高生长速度,使其提前出栏。In this study, we feed 28 Maiwa yak in four levels: three group supply feed in three levels and the forth group (CK) is not supply feed besides grazing. The average weight gain of three groups that supply feed is 67.73kg, the average daily weight gain is 451.67g, and the rate of relative weight gain is 47%. The average weight gain of the group (A) which with highest supply feed is more than the group (D) which not supply feed by 34.5kg and A has more daily weight gain than D by 230g. So, we can conclude that supply feed to yak in warm season can improve the growth rate of the yak and shorten the feeding time in alpine pasturing area.
