This study was conducted to find the effect of feeding marine fish (1 and 2%) on egg yolk fatty acids, blood cholesterol and egg quality in laying hens. Forty five laying hens (Hisex), 20 weeks old, were divided into three groups (15 birds per treatment). The diets were formulated to meet the requirement of egg production. Two formulae of diets were prepared by inclusion of marine fishmeal (1 and 2%). Results revealed that feeding fish meal at a concentration of 1 and 2% in a basal diet of laying hens for two months resulted in significant elevation of poly unsaturated fatty acids and omega-3 FA, contents of egg yolk compared to the control group with no effect on production traits except the egg number and egg shell thickness. Fish meal had significantly reduced plasma total lipids, triglycerides, cholesterol and low density lipoproteins, while high density lipoprotein was increased. The results showed that inclusion of 1 and 2% marine fish improved egg quality, egg yolk fatty acids and blood cholesterol profile in laying hens.
