SCFA: short chain fatty acids; MCFA: medium chain fatty acids; LCFA: long chain fatty acids; PUFA: polyunsaturated fatty acids; MUFA: monounsaturated fatty acids; SFA: saturated fatty acids; UFA: unsaturated fatty acids; 1 results are given as means of groups (n = 5 = subgroups); 2 Control, Cornus and CorOrThym represent groups of ewes fed a basal diet supplemented with corresponding plant extracts; 3 the Δ−9 desaturase activity indexes were calculated using the following four ratios: C14:1/C14:0, C16:1/C16:0, C18:1/C18:0 and C18:2cis9,trans-11/C18:1 trans11; 4 SEM = standard error of the mean. NS = not significant.
