Effects of BAs on mRNA levels of hepatic lipid metabolism-related genes in 42-day-old broiler chickens fed diets with different fat levels. A PPARγ; B ATGL; C LPL; D FAS; E ME; F ACC; G C/EPBα; H SREBP1; I AMPK; J CPT1; K PPARα; L FATP1; M ADPN; N ADPR1; O ADPR2. Data are presented as the mean ± SEM (n = 8). The P values in the top left corner of each panel represent the results of two-way ANOVA. PDiet < 0.05 indicates a significant effect of dietary fat level on the respective parameter, PBAs < 0.05 indicates a significant effect of BAs on the respective parameter, and PDiet×BAs < 0.05 indicates a significant interaction effect between dietary fat level and BAs on the respective parameter. *P < 0.05, **P < 0.01
