This study evaluated the nutraceutical effects of organic Selenium and vitamin E supplementation on performance, egg quality and antioxidant protection of Japanese quails. Forty-two posture cages with six birds each were randomly set in seven treatments. Each treatment consisted of the addition of 200 IU of vitamin E/kg of feed and increasing levels of organic Selenium. Significant differences were found in α-Tocopherol deposition, enzymatic activity of glutathione peroxidase (GSH-Px) and oxidative bioindicator malondialdehyde (MDA) in egg yolk with vitamin E supplementation. We concluded that supplementing 200mg of vitamin E and 0.30 ppm organic Selenium did not affect bird performance, but improved egg quality and shelf life.

Keywords : α-Tocopherol; Glutathione peroxidase; Malondialdehyde.
