摘　　要：[目的]研究不同的精料饲喂量对德宏高峰牛育肥效益的影响,为养殖户进行德宏高峰牛育肥合理使用精料饲喂量提供理论依据。[方法]将试验分为4个组,每组10头,按试验1组、试验2组、试验3组、试验4组分别以每头每天1.5 kg,2 kg,2.5 kg,3 kg精料进行饲喂,通过90 d育肥,分析得出效益最好的精料饲喂量组。[结果]结果表明,试验1组平均日增重0.64 kg,每天每头牛可获利7.40元;试验2组平均日增重0.712 kg,每天每头牛可获利8.02元;试验3组平均日增重0.748 kg,每天每头牛可获利7.57元;试验4组平均日增重0.779 kg,每天每头牛可获利6.96元。[结论]德宏高峰牛育肥按每头每天饲喂精料2 kg经济效益最好,即按体重1%左右给予精料育肥德宏高峰牛效益最可观。[Objective]The objective was to study the effect of different concentrate amount on the fattening benefit in Dehong humped cattle,and to provide theoretical basis for farmers to use the concentrate reasonably.[Methods]The experiment was divided into 4 groups,10 cattle pre each group.Each animal was fed with 1.5 kg,2 kg,2.5 kg and 3 kg concentrate every day for the groups as experiment 1,experiment 2,experiment 3 and experiment 4.And,the optimal concentrate amount was determined through 90 days fattening.[Results]The results showed that the average daily gain(ADG)of group 1 was 0.64 kg,and the profit was 7.40 yuan/herd/day;the ADG of group 2 was 0.712 kg,and the profit was 8.02 yuan/herd/day;the ADG of group 3 was 0.748 kg,and the profit was 7.57 yuan/herd/day;the ADG of group 4 was 0.779 kg,and the profit was 6.96 yuan/herd/day.[Conclusion]Feeding 2 kg concentrate/herd/day,the optimal economic benefit was gained,that was to say,the better benefit was to provide 1%concentrate of body weight in Dehong humped cattle.
