See Table S1 in supplementary material for the complete FA composition including minor FA results. ¹ Data were expressed as the mean of the five replicates from each dietary treatment (). ² Standard error of the mean. ³ values obtained by ANOVA (). Values in bold were significant (). Differences between dietary treatments found with Scheffé’s post hoc test were noted in the same row as .
