The effect of adding two organic acids(formic acid, acetic acid). with broiler drink water was tested to evaluate their efficacy on the their performance and health Groups treatment consumed amounts of feed that are greater than the control but for The results in the six trials showed superiority of the feed conversion ratio and the final weight of broiler in the two groups that was added complex to its drink water, compared to the control with significant differences at 0.05. There was no significant difference between the replicates of each trial on its own while the results of laboratory parasite testing of samples litter showed that the number of oocysts in the litter was the lowest in the treatment groups with significant differences compared to the control.
