Abstract Organic acids have exhibited great potential as an antibiotic replacement and as an additive work tremendously for health maintenance of broiler chicken. To explore more about organic acids, a total of 900 day-old broiler chicks (Cobb-500) were procured from a local hatchery and distributed into 9 treatment groups having 5 replicates of 20 birds each; duration of the biological trial was of 35 days. Group T1 served as control group without any dietary supplementation. Other groups T2 and T3 were boosted with different levels (125 g/ton and 250 g/ton) of enramycin (antibiotic), T4, T5, and T6 were supplemented with different levels (2 kg/ton, 3 kg/ton, and 4 kg/ton) of ammonium formate and ammonium propionate, and T7, T8, and T9 were fed with different levels (2 kg/ton, 3 kg/ton, and 4 kg/ton) of calcium formate and calcium propionate. The findings declared significant improvement (P < 0.05) in body weight gain and FCR in groups T3, T5, and T9 while feed intake was not affected. Carcass evaluation depicted significantly better (P < 0.05) dressed and eviscerated weight along with carcass yield (T5, T7, T8, T9). Broilers fed organic acid supplemented diet had significantly lower (P < 0.05) total bacterial count (T3, T5, T8, T9) and positively improved (P < 0.05) villi length (T5, T6, T9) as compared with control group. However, total protein, globulin, HDL, and LDL levels were determined to be non-significant (P > 0.05) among different organic acids treatments. Hence, organic acids can be utilized as a better replacement for antibiotics. Supplementation of organic acids at a dose rate of 3 kg/ton and 4 kg/ton is recommended for efficient performance of broilers. Keywords Antibiotics . Broilers . Growth performance . Gut health
Introduction The aim of poultry production is to attain maximum growth and better feed conversion ratio (FCR), with optimum bird’s performance during the whole rearing period. A balanced diet with effective feed additives is necessary for efficient growth and production of the poultry industry. Utilization of specific feed additives results in better production and effective feed conversion to some extent (Khan and Iqbal 2016; Çetingül
