^a,b In a row, means with common superscripts do not differ (p > 0.05); ¹ Dietary treatments: CON = a commercial broiler diet without Zn-bacitracin antibiotic growth promoter; ZnB = a commercial broiler diet with Zn-bacitracin antibiotic growth promoter; MinEnz = CON + protease + chelated minerals; MinEnzOrg = CON + protease + chelated minerals + fumaric and benzoic organic acids; MinEnzPro = CON + protease + chelated minerals + live Bacillus probiotic; ² ALT = alanine transaminase; ³ AST = aspartate aminotransferase.
