摘　　要：试验结果表明 :在暖棚舍饲条件下 ,第 1组牦牛的绝对增重、相对增重分别比第 2组和对照组高 5 .9kg、4.94%和 3 1.44 %、2 6.5 9% ,第 2组比对照组高 2 5 .5 4kg和 2 1.65 % ,两处理之间同一放牧期牦牛的日增重之间差异极显著 (P <0 .0 1) ,处理内不同放牧期牦牛的日增重之间差异显著 (P <0 .0 5 ) ,而且牦牛的日增重与采食量之间呈极显著的线性回归关系Y =-aX +b ,(a >0 )。The experiment results showed that under hothouse feeding,absolute gain in weight and,relative gain in weight of the yaks in first group were 5.9kg,4.94% and 31.44kg,26.59% more than those of the yaks in second and control group,and ones of the yaks in second group were 5.54kg,21.65% and 0.4kg/head·d more than those of the yaks in control group,there was a greatly significant differences in daily gain of yaks between both treatment groups in same pasture period(P<0.01).but there was the significant difference in daily gain of yaks with same treatment in different posture period(P<0.05).And there was a greatly significant linear regression relation between gain and intake,Y=-aX+b,(a>0).
