1

Data are means of 16 egg samples per each treatment.

2

n−6 PUFA biosynthesis pathway enzyme activity (Δ6-desaturase, elongase, and Δ5-desaturase) was calculated as ratio of 20:4 n−6 to 18:2 n−6.

3

n−3 polyunsaturated fatty acid biosynthesis pathway enzyme activity (Δ6-desaturase, elongase, and Δ5-desaturase) was calculated as ratio of 20:5 n−3 to 18:3 n−3.

4

Microalgae (Aurantiochytrium limacinum) fermentation product, as a source of docosahexaenoic acid (DHA).

5

Coextruded full-fat flaxseed and pulse mixture (FFF, 1:1 wt/wt), as a source of α-linolenic acid (ALA).
