SFA, saturated fatty acid ; MUFA, monounsaturated fatty acid; PUFA,polyunsaturated fatty acid; Σ, total; UI, unsaturation index (the number double bonds per 100 fatty acid molecules)

Superscript letters indicate significant differences between the values derived for mouse (m), sheep (s) and cow (c) at a minimum P<0.05. n-3, n-6, n-9 denote the location of the first double bond from the methyl end of the molecule. Values are mean ± s.e.m. (N=4)
