Likewise, microalgae may be cultivated for their advantageous fatty acid profile with notable enrichment in omega-3 (n-3) polyunsaturated fatty acids (PUFA) including arachidonic acid, docohexaenoic acid (DHA), eicosapentaenoic acid (EPA), and γ–linoleic acid. Microalgal biomass or oil may be supplied in the feed of ruminants to manipulate their milk fatty acid composition.
