Abstract
The effects of feeding menhaden, flax, palm, or sunflower oils with to‐copherols to laying hens on the internal quality of eggs during 40‐days storage were examined. Dietary tocopherols increased (P < 0.05) the tocopherol content of eggs. Addition of tocopherols increased (P < 0.05) the Haugh unit at 40‐days storage in menhaden, flax, and palm oil eggs. Dietary tocopherols increased (P < 0.05) the content of 20:5 n‐3 and 22:6 n‐3 in menhaden oil eggs. At 40‐days storage, the TBA values in menhaden oil eggs were reduced (P < 0.05) by dietary tocopherols. Storage decreased (P < 0.05) 8‐tocopherol in the flax and sunflower oil eggs. Yolk pH increased during storage (P < 0.05).
