^a–cValues within a column with different letters differ significantly (P < 0.05).

¹NC: negative control group received corn-soybean meal diet without any challenge and additives; PC: positive control group received NC diet inoculated with E. coli without any additives; AMP: PC received group supplemented with 20 mg antimicrobial peptide/kg diet; Antibiotic: PC received group supplemented with 45 mg antibiotic (bacitracin methylene disalicylate)/kg diet.

²SEM: standard error of means (results are given as means (n = 12) for each treatment).
