Abstract
ABSTRACT The objective of this study was to examine the effects of enriching the diet with Omega-3 fatty acids on the productive performance, yolk fatty acid profiles, oxidative stability, blood biochemistry, and immune system of laying hens. Enriching the diet with Omega-3 improved egg production and FCR (P < 0.05). Docosahexaenoic acid (DHA) and total omega-3 fatty acids in the yolk increased linearly with Salomega level (P < 0.05). Serum cholesterol and triglyceride decreased, but HDL content increased parallel to the Salomega level in the diet (P < 0.05). The MDA level in the yolk of bird eggs of the 3 or 4% Salomega treatment was higher than the MDA level of the control group (P < 0.05). In conclusion, the enrichment of laying hens’ diet with 3 and 4% salomega can enhance egg production, elevate the levels of Omega-3 fatty acids, and decrease the oxidative stability of yolk lipids.
