Normal = normal soybean meal diet, Low = low soybean meal diet; SEM = standard error of means; SBM = soybean meal; TP = total protein, ALB = albumin, GLOB = globulin, A/G = albumin/globulin, ALT = Alanine Aminotransferase, AST = Aspartate Aminotransferase, BUN = Blood Urea Nitrogen. Within a row, the mean values with different letters differ at p < 0.05.
