摘要
选择60头16月龄(420 kg左右)的纯种安格斯公牛,依据体重和类型随机分为3组,试验1组和试验2组分别用于添加不同的营养调控产品,基础日粮一致。试验1组添加营养调控产品Ⅰ,试验2组添加营养调控产品Ⅱ,剂量均为100 g/d。试验结果表明:在2种营养调控产品配合基础日粮饲喂,其正试期平均日增重分别为1.21 kg和1.16 kg。试验1组平均日增重明显高于对照组,差异显著(P<0.05),经济效益相当明显。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1组最佳。
Sixty black Angus bulls of16months(420kg)were divided into three groups according to their weight and types,among them group one and two were fed with different nutritional regulation products and uniform basal diet,and group three(control group)were only fed with basal diet.Experiment group one and two group were fed different nutritional regulation products on the uniform basic diet.The dose was100g/d.Results showed that the average daily gain weight of the two nutritional regulation products was1.21kg and1.16kg respectively.Test weight average daily gain one group was obviously higher than that of control group(P<0.05),and the economic benefits was fairly obvious.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 gained the best economic benefit.
