1 Values are means of 12 samples with 2 birds per replicate. ab Mean value within a role with no common superscript differ significantly (p < 0.05). CON = the control group, AT = the antibiotic (zinc bacitracin), BA = benzoic acid, AL-H = high level amylase, AL-H = high level amylase, AL-L = low level amylase. UA = uric acid, AKP = alkaline phosphatase, iNOS = inducible nitric oxide synthase, CK = creatine kinase, LDH = lactate dehydrogenase, SEM = standard error.
