Effects of dietary butyrate supplementation on expression of PGC-1α in both mRNA (A) and protein (B) levels in LT muscle of finishing pigs. RT–PCR and western blotting were conducted to determine the mRNA and protein expression of PGC-1α, respectively. β-actin was used as a control. Control, basal diet; Butyrate, basal diet with 0.3 % sodium butyrate. Data are the means ± SEM, n = 8. *P < 0.05; **P < 0.01.
