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 kidney & liver function tests, serum protein and mineral profile among the treatment groups. And in case of lipid profile OAs supplementation showed significantly beneficial impact. The levels of serum profile parameters were in normal range, that suggesting good nutritional status of the birds in all the treatment groups. Salts of organic acids (OAs) could be safely supplemented as an alternative to antibiotic growth promoters (AGPs) in the commercial broiler diet to lower the risk of residues in the meat and to avoid the antibiotic resistance (if any) to the consumers without impair the serum profile and birds health.enVeterinary ScienceArticle
