1 c = cis; t = trans; SFA = saturated fatty acids; MUFA = monounsaturated fatty acids; PUFA = polyunsaturated fatty acids. 2 BCFA = branched chain fatty acids. 3 LC-PUFA = long chain—polyunsaturated fatty acids. 4 alt RBH ALA = alternative rumen biohydrogenation of α-linolenic acid. 5 SCFA = short chain fatty acids. 6 OCFA = odd chain fatty acids. 7 RBH = rumen biohydrogenation. Values > |0.60| are highlighted using bold.
