CON: control; LCLA: low conjugated linoleic acid; HCLA: high conjugated linoleic acid.
The data are expressed as the percentage of total identified fatty acids.
^aTotal SFA = sum of C12:0 + C14:0 + C16:0 + C18:0.
^bTotal MUFA = sum of C16:1 + C18:1n-9.
^cTotal n-3 PUFA = C18:3n-3.
^dTotal n-6 PUFA = sum of C18:2n-6 + C20:4n-6.
^en-6 : n-3 FAR = sum of (C18:2n-6 + C20:4n-6) ÷ (C18:3n-3).
^fTotal CLA = sum of cis-9, trans-11 CLA + trans-10, cis-12 CLA.
Data presented as mean with pooled SEM ( = 10). ^a,bMean values within a row with no common superscript differ significantly ( < 0.05).
