¹Values are means of four replicates. Values in a row that do not have the same superscript are significantly different at based on Tukey’s multiple range test. ²Pooled S.E.M.: pooled standard error of means. ³. ⁴. ⁵. ⁶Liver redness value was assessed visually by using the color card (SalmoFan™, DSM, Netherlands). ⁷NEFA: nonesterified fatty acid. ⁸HDL-C: high-density lipoprotein-cholesterol. ⁹LDL-C: low-density lipoprotein-cholesterol.
