An experiment was conducted with 240 day old commercial broiler chicks to evaluate the effectiveness of replacing antibiotic growth promoters with organic acid salts on the production performance. Treatment diets were supplemented with lincomycin HCl (4.4 ppm), bacitracin methylene disalicylate (BMD; 50 ppm), each two levels (ppm) of calcium propionate (1000, 2000) and coated sodium butyrate (500, 1000) either alone or in combination (1000+500) with control. The results showed that there was no significant difference in body weight, body weight gain, cumulative feed intake, FCR and livability among the treatment groups. However, the calcium propionate (2000) group had the highest body weight gain with 6.48% more than lower levels (1000). Improved EEF and COP were observed in organic acid treated groups. Calcium propionate and coated sodium butyrate could be safely supplemented as an alternative to antibiotic growth promoters (AGPs) in the commercial broiler diet without affecting the production performance.
