Inclusion of Dietary Defatted Microalgae Dose-Dependently Enriches ω-3 Fatty Acids in Egg Yolk and Tissues of Laying Hens.

Background: The potential for dietary microalgae to enrich eggs of laying hens with ω-3 (n-3) fatty acids, and the mechanisms involved, are unclear.

Objectives: The aim of this study was to determine the effects and molecular regulation of a defatted Nannochloropsis oceanica microalgae (DNOM) biomass on the enrichment of the eggs and tissues of laying hens with ω-3 fatty acids.

Methods: Fifty Shaver-White Leghorn hens (46 wk of age, body weight: 1.

Creating ω-3 Fatty-Acid-Enriched Chicken Using Defatted Green Microalgal Biomass.

This study was to create an ω-3 (n-3) fatty-acid-enriched chicken product using defatted green microalgae (DGA, Nannochloropsis oceanica) biomass out of biofuel research. Hatching Ross broiler chicks were fed a corn-soybean meal diet containing 0 (control), 2, 4, 8, or 16% DGA for 6 weeks (n = 6 cages/diet). The DGA inclusion resulted in a linear (p < 0.
