Six hundreds of one day old male broiler chicks (ROSS 308) were divided into 4 groups and 6 replications with 25 broilers/each. Total of 4 treatment groups of drinking water were performed; 1) control (without formic acid supplementation), 2) formic acid 0.01%, 3) formic acid 0.05% and 4) formic acid 0.10%. Adding formic acid into drinking water significantly decreased ph of the water. At the end of the experiment (42 days), adding formic acid at 0.01 and 0.05% not affected production performance compared to control group. Conversely, adding formic acid at 0.10% significantly depressed production performance (P<0.01). However, when compared with the control group, drumstick (% of live body weight) significantly increased by adding 0.05 and 0.01% formic acid (P<0.01). In addition, adding formic acid into drinking water induced E.coli counts of water (P<0.01), However, adding formic acid into drinking water slightly increased population of Lactobacillus spp. in digestive tract. This study suggested that adding formic acid in drinking water at 0.01 and 0.05% had no effect on production performance, increased portion of leg meat and tend to promote growth of beneficial bacteria population.
