Abstract:	The objective of the present study was to evaluate the evolution of α-tocopherol concentration in egg during time as a : response of dietary supplementation with 200 mg/kg diet of α-tocopheryl acetate, and the effect of dietary oil on this : parameter. Forty hens were randomly distributed into 2 treatments resulting of the supplementation of a basal diet containing 200 mg/kg α-tocopheryl acetate with 5% linseed oil or sunflower oil. α-Tocopherol concentration ofeggs was measured at 0, 4, 9, H, 19, and 50 days after inclusion of the experimental diets. α-Tocopherol concentration in egg increased after the fourth day of feeding, reaching its maximum level at 14 days (168 pg/g egg), after which it descended 10-12% until 19 days, remaining constant until 50 days (145 pg/g egg). No differences were observed between dietary oils in the deposition pattern of α-tocopherol.
