Effects of parental dietary linoleic acid on the mRNA expression of hepatic lipid metabolism–related genes in domestic pigeon squabs. (A) mRNA expression of fatty acid synthase (FAS), (B) mRNA expression of acetyl-CoA carboxylase (ACC), (C) mRNA expression of carnitine palmitoyltransferase 1 (CPT1), (D) mRNA expression of acyl-CoA (ACO), (E) mRNA expression of peroxisome proliferator-activated receptor α (PPARα), and (F) mRNA expression of peroxisome proliferator-activated receptor γ (PPARγ). Control, control group; LA1%, 1% linoleic acid addition group; LA2%, 2% linoleic acid addition group; LA4%, 4% linoleic acid addition group. Values are means ± SEM of 6 squabs. a,b Means sharing no common superscripts differ significantly (Tukey test, P < 0.05).
