NS not significant, SD standard deviation

^{a, b, c}Group means (M) with different superscript letters within rows and within the same zinc level significantly differ (Tukey test, p < 0.05)

^dANOVA after ln transformation of the data

^eThe sum of saturated fatty acids (SFA) includes small amounts of 14:0 (<0.6 mol%) and 21:0 (<0.5 mol%)

^fThe sum of monounsaturated fatty acids (MUFA) includes small amounts of 16:1 (about 1.2 mol%), 20:1 (<0.1 mol%) and 22:1 (about 0.8 mol%) in the case of the CT groups, and 20:1 (0.2 mol%) and 22:1 (about 1.0 mol%) in the case of the SF groups
