This study aimed to investigate the effi ciency of 0.5 % humate supplementation in Japanese quails’ diet on performance, carcass and internal organs characteristics, bone ash, and revenue. A total of 80 quail, 10 day old, were divided into 2 groups (control and humate), 5 replicates with equal body weights. The control group was fed with unsupplemented basal diet and humate group was fed with 0.5% humate supplemented diet for 4 weeks. At the 14th and 28th day of the study live weight, live weight gain, feed intake and feed conversion ratio were determined. At the end of the study, weights and ratio of the edible internal organs (liver, heart and gizzard), carcass (hot and cold) weight and yield were determined in slaughtered quails’. Bone ash level was analyzed from left tibias of slaughtered quails. In humate group, live weight, live weight gain, feed conversion ratio and bone ash level were increased (P<0.05). Humate supplementation to diet, were positively affected the carcass weight (hot and cold) and yield, but were not affected the weight and ratio of edible internal organs (liver, heart and gizzard). In the economic evaluation, fattening performance was better than control group compared to humate group and provided 0.7 TL/quail (32.5 %) extra revenue. In the end of study, 0.5 % humate supplementation on diet of quail was concluded that be a correct decision due to positive effect on fattening performance and economical benefi ts
