Abstract:	The present study was carried out to evaluate the effect ofdietary supplementation with α-tocopheryl acetate (a-TA) on α-tocopherol (α-Toc) content and lipid oxidation (TBA values)in fresh, cooked and scrambled eggs enriched with co-3 fatty acids. Four treatments were formulated from a basal diet containing4% linseed oil (L) or fish oil(F)with0 or 100 mg of a-TA/kg of feed. Dietary supplementation with 100 mg/kg a-TA significantly increased α-Toc content ofeggs. Fresh, cooked and scrambled eggs from F treatments showed lower α-Toc content than those from L and their processing significantly decreased the α-Toc content. Moreover, processing ofeggs significantly increase lipid oxidation. TBA values in cooked and scrambled eggs were significantly reduced when 100 mg a-TA /kg of feed were supplemented to the diet. Reduction ofTBA values caused by α-TA supplementation was more pronounced in eggs from F treatments (0. 72% C20:5 0)3,'7. 15% C22. 6 m3) than in those from L (8. 27%C18:3 ro3).
