¹ Values are means of six replicates per treatment. Fatty acid content is based on freeze-dried condition. Group C = controls, Group MM = melatonin implanted in May group, Group MJ = melatonin implanted in June
² SFA = saturated fatty acid
³ MUFA = monounsaturated fatty acid
⁴ PUFA = polyunsaturated fatty acid
^{a, b} Mean in the same row with different superscripts are significantly different (P < 0.05)
