The Adaptive Characteristics of Cholesterol and Bile Acid Metabolism in Nile Tilapia Fed a High-Fat Diet

Figure 1

Effects of HFD on growth performance, organ indices, serum lipid profiles, and liver health in Nile tilapia after 4-week and 8-week feeding trials. (a) Body weight ( tanks, 30 fish/tank); (b) survival rate (SR, tanks); (c) condition factor (CF, ); (d) mesenteric fat index (MFI, ); (e) hepatosomatic index (HSI, ); (f, g) triglyceride (TG) and free fatty acid (FFA) in serum (); (h, i) total cholesterol (TC) and free cholesterol (FC) in serum (); (j) low-density lipoprotein cholesterol (LDL-C) in serum (); (k, l) serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) enzyme activities (). Data are represented as ; asterisks indicate the differences between the C and HFD groups in the same feeding trial, , , ; hash symbols indicate the differences between 4-week and 8-week feeding trials of the same lipid level diet, ^#, ^##, ^###; C: control diet; HFD: high-fat diet. . . . .
