Abstract

       Omega-3 fatty acids (n-3 FA) are known to possess beneficial effects on human health especially the long chain members (>20C; VLC n-3 FA). High-α linolenic acid flaxseed oil (FLAX oil) is known to be the richest plant source with n-3 FA (58% ALA vs 50% in regular flaxseed oil). Broilers and layers were fed FLAX oil in order to assess their ability to enrich the breast tissues with n-3 FA. In the broilers experiment, FLAX oil was added at a level of 2.25% of the diet while in laying hens, was added at 4% of the diet. The growth performance was not affected by the dietary treatments in both broilers and layers. The fatty acid profile of the liver was affected by the dietary treatments where the total n-3 FA was higher in laying hens, but the total VLCn-3 FA was greater in broilers.
