摘　　要：试验比较了不同粗纤维含量颗粒料对奶公犊牛育肥的经济效益。结果表明,粗纤维含量较高组的犊牛日增重较高、总产出及纯收入更大;相同颗粒料组内,体重较大组的犊牛增重相对较多。说明日增重及纯收入与颗粒料中粗纤维含量呈正比。The economic benefits of fattening dairy male calves with different coarse fiber content granules were compared.The results show that the higher the crude fiber content in pellet feed,the higher the daily gain of calves,the greater the total output and net income.For the same pellet feed group,the weight gain is relatively higher in larger group.It shows that the daily gain and net income are proportional to the crude fiber content in pellet feeds.
