摘　　要：选择60头450kg左右的荷斯坦公牛,依据体重和类型随机分为3组,试验1组和试验2组分别使用不同的营养调控剂,基础日粮一致;对照组仅饲喂基础日粮。试验1组使用营养调控剂A,试验2组使用营养调控剂B,剂量均为100g/d。结果表明,使用2种不同营养调控剂配合基础日粮饲喂荷斯坦公牛,其正试期平均日增重分别为2.10和2.28kg,试验2组平均日增重明显高于对照组,差异显著(P<0.05);经济效益明显增加,试验1组和试验2组增重价值、育肥收入和日均收入都明显高于对照组,经济效益以试验2组为最佳。Sixty Holstein hulls of about 450 kg were divided into three groups according to weight and types, among them group one and two were fed with different nutritive regulating agents and uniform basal diet, and group three （control group） were only fed with basal diet. Group one was fed with nutritive regulating agent A at dosage of 100 g/d, and group two was fed with nutritive regulating agent B at dosage of 100 g/d. Results showed that after the group one and two were fed with different nutritive regulating agents and uniform basal diet, their average daily gains were 2.10 and 2.28 kg, respectively, among them the average daily gain of group two was significantly higher than that of control group; the value of weight gain, fattening income and daily average income of group one and two were all obviously higher than that of control group, and group two had the highest economic benefit.
