¹ The complete FA datasets (mole/day and g/100 g) are reported in Additional file 1 (Tables S6 and S7).

²Effect of day.

³ Fatty acid with carbon length 4÷14 (except 11)/tot FA (except 16:0 and 16:1).

⁴ Fatty acid with carbon length >16 (included 11 and 15)/tot FA (except 16:0 and 16:1).

⁵ ACE corrected (Additional file 1, Table S6).

⁶ACE corrected without considering odd chain FA (11:0, 15:0) (Additional file 1, Table S6).

⁷ Overall Δ⁹ desaturase index, calculated from (14:1 c9 + 16:1 c9 + 18:1 c9 + 18:2 c9, t11)/(14:0 + 14:1 c9 + 16:0 + 16:1 c9 + 18:0 + 18:1 c9 + 18:1 t11 + 18:1 c9, t11)

^a,b,c denote P < 0.05
