This experiment was conducted to investigate the effect of humic acid on fattening performance, carcass quality and some blood parameters of broilers. Therefore, a total of 160 day-old Ross 308 broiler chicks were assigned to 2 treatments with 4 replicates each containing 20 chicks. The treatment groups were employed: Control group (C) without additive and experimental group (H) supplemented with 2.5 kg ton(-1) humic acid. Experimental period lasted 42 days. There was no statistical difference in the cases of live weight, live weight gain, feed intake, feed conversion ratio, hot and cold carcass yield, ileum, cecum lengths, total intestinal weight, serum total protein, triglyceride, cholesterol scores among the groups of C and H. As a result, the values obtained by the addition of humates to broiler ratios are generally in a acceptable level.
