Flaxseed cake produced during flax oil production is rich in protein, and could be utilized in the production of omega-3 enriched eggs or value added eggs. But the presence of anti-nutrients in flaxseed cake adversely affects the bird and egg characteristics. Supplementation of pyridoxine may prove beneficial as noted by earlier research. In our study, we divided 30 layer birds into three groups and supplemented them with different combination feeds containing: (A) control ration, (B) fresh flax seed cake with pyridoxine and (C) fresh flax seed cake without pyridoxine. Crushed 2% flaxseed was also added to the flaxseed cake groups for deposition of sufficient omega-3 fatty acids into the eggs. Supplementation was given for a period of 4 weeks and egg as well as bird characteristics observed. Birds fed pyridoxine showed better incorporation of omega-3 fatty acids into the egg yolk. Supplementation of flaxseed cake with pyridoxine resulted in better yields of omega-3 eggs as well as improved health of layer birds.
