Highlight of significant differences (p < 0.05) ± S.E.M. in fatty acid composition, at 180 days-old, between pigs born from sows treated or not with hydroxytyrosol and linseed oil during pregnancy (groups T, n = 20, and C, n = 17, respectively). Complete data are offered in Supplementary Tables S13–S21.
