摘　　要：对 2 0头秦川牛青年母牛 ( 1 .5岁 )和 1 0头秦川牛犊牛 ( 0 .5岁 )进行了“万力补”饲料添加剂饲养对比试验。犊牛试验结果为 :试验组犊牛平均日增重 32 5 g/d,对照组犊牛平均日增重32 0 g/d,试验结果表明用“万力补”饲料添加剂饲喂秦川牛犊牛效果不显著 ,在犊牛期可不予添加 ;青年牛试验结果为 :试验组水平 平均日增重 35 5 g/d,水平 平均日增重 494g/d,水平 平均日增重 5 0 0 g/d,对照组平均日增重为 - 5 0 g/d,试验结果表明用“万力补”饲料添加剂饲喂秦川牛青年母牛效果十分显著 ,生产中可予以采用 ;试验结果得出的理想添加量为每头牛每天添加“万力补”饲料添加剂 1 0 0Twenty Qinchuan heifers and ten Qinchuan calves were supplemented with MAGANPAC. Average daily gain of calves fed with or without MAGANPAC was 325 g/d and 320 g/d, which is not significantly different (P>0.05). Twenty Qinchuan heifers were divided into four groups. One was control group and other three groups were supplemented with MAGANPAC at different levels. Average daily gain of the control group and the supplemented groups was -50 g/d, 355 g/d, 494 g/d and 500 g/d, respectively, which demonstrated that MAGANPAC had significant effect on growth trait of Qinchuan heifer and the best dosage of MAGANPAC per cattle per day was 100 g/d.
