The effect of pregnancy on body weight, liver weight, the serum lipid profiles and lipid profiles of the liver. (a) Body weight and liver weight during pregnancy or lactation. (b) Serum TC, LDL-c and HDL-c levels. (c) Serum TG and NEFA levels. (d–f) TG content, TC content and FC content in the liver normalized by liver tissue weight in grams (n = 9–12 per group). (g) First row: Representative gross morphology of the uterus. Second row: Representative gross morphology of the liver. Third row: Representative images of H&E-stained liver tissue (magnification, 200 ×). Last row: Representative images of oil red O-stained liver tissue (magnification, 400 ×). Each bar represents the mean ± SEM of the indicated variable. Statistical analyses were performed with one-way ANOVA. *P < 0.05, **P < 0.01 versus the V or P19 group; ns, not significant
