a − cValues with different superscripts differ significantly (P < .05) in the same row; “a”, “b”, “c” indicate significant difference from each other while “ab” is not significant. Values are means ± SD (mg/g) for 10 laying hens per group.
Differences were tested by Duncan multiple range test. MUFA = monounsaturated fatty acids, PUSA = polyunsaturated fatty acids, SFA = saturated fatty acids.
