| [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. 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.
