This study was conducted to evaluate the effect of acetic acid and diet energy on productive performance and intestinal microflora in 216 day-old broiler chicks. Chicks were divided to 2 parts and each part was split into 9 groups (12 birds) after six days. The first and second parts of chicks were fed by control (N) and high energy (H) diet, respectively. Each of the amounts of 0 (A0), 0.7(A0.7) and 1.4 (A1.4) acetic acid were added to diets of three groups of both parts in 3 replicates. A bird of each group in the day 18, 28 and 38 was slaughtered and its ileosecal contents were picked. CFU/g of Coliforms, E. coli and lactobacillus of samples were determined. The results showed that the lowest feed conversion ratio was achieved by 1.4% acetic acid (P<0.05). There was intraction effect of time and acetic acid on CFU/g of Coliforms and E. coli (P<0.05). On day 38, CFU/g of Coliforms obtained by 0.7 and 1.4 % acetic acid was lower than 0% acetic acid (P<0.05). CFU/g of E. coli with 0.7 % acetic acid, achieved on day 28 was higher than on day 38 (P<0.05). The lowest CFU/g of lactobacillus was obtained with 0% acetic acid (P<0.05). Conclusion, the addition of acetic acid up to 1.4% to diet of broilers can improve feed conversion ratio, enhance the growth of lactobacilli and prevent the growth of Coliforms and E. coli in the digestive contents.
