CTRL, control diet; CBS, cocoa bean shell diet; DT, dietary treatment; SD, sampling date; c, cis; t, trans; MUFA, monounsaturated fatty acids: DI, desaturase index.

^aTotal number of samples for each group equal to 44 (11 goats × 4 sampling dates).

^bProbability: ***P ≤ 0.001; **P ≤ 0.01; *P ≤ 0.05; ^†0.05 < P ≤ 0.10; ns, not significant (P > 0.05). The effect of the interaction between dietary treatment and sampling date (DT × SD) was not significant; therefore, significance is only presented for the main effects.

^cDesaturase indexes. DI₁₄: C14:1 c9/C14:0; DI₁₆: C16:1 c9/C16:0; DI₁₈: C18:1 c9/C18:0.
