¹ This column presents the mean value of high-fat groups from the contrast between low-fat group and four high-fat groups
² The low-fat group is excluded from the statistical analysis of fat sources
³ Each treatment contained 8 replicates (n = 8)
^* Significant differences between fat levels are marked with an asterisk in the low-fat column (P ≤ 0.05)
^a–d Significant differences between the fat sources are marked with different superscripts (P ≤ 0.05)
