Expression profiles of the lipid metabolic genes during dry period, early lactation, and peak of lactation. The expression levels of lipid metabolic genes are shown based on FPKM values; the genes are divided into SREBPs and PPARα (A), lipid transport (B), lipogenesis (C), cholesterol metabolism (D), fatty acid transport (E), and fatty acid oxidation (F) categories; and the differentially expressed genes are labeled with an asterisk.
