SEM, standard error of the mean; ANOVA, analysis of variance; TBILI, total bilirubin; CRE, creatinine; UN, urea nitrogen; ALP, alkaline phosphatase; ALT, alanine aminotransferase; AST, aspartate aminotransferase; TP, total protein; ALB, albumin; GLU, glucose.

¹⁾Data are the means of six replicates of one pig per pen.

^abcMeans within the same column lacking a common superscript letter differ (p<0.05).
