Fatty acid profile of peripheral blood mononuclear cells from cows that received a control fat preparation (CON, n = 15) or 50 g/d (CLA-50, n = 15) and 100 g/d (CLA-100, n = 16) of a CLA supplement. Blood samples were taken after 70 and 140 days of supplementation and samples were pooled for each cow. Results are expressed as % of total fatty acid methyl esters, means ± standard error. p < 0.1 in italics and indicate tendencies. p <0.05 in bold and indicate significant differences, ab: different letters within a row indicate significant differences, p < 0.05, Tukey test.
^† Minor FA contain fatty acids which concentration is less than 1 % of all fatty acids except CLA.
^‡ includes CLA.
c = cis, t = trans, SFA = saturated fatty acids, MUFA = monounsaturated fatty acids, PUFA = polyunsaturated fatty acids, MC-FA = medium chain fatty acid.
