Abstract :The aim of this study was to determine the effects of Vitamin E and organic or inorganic selenium sources combined with Vitamin E on growth performance and plasma and tissue glutathione peroxidase activity in broilers. A total of 168, one-day old female commercial broiler chicks (Hubbard strain) were randomly allotted to one control and three treatment groups, each containing 42 birds. All experimental groups were replicated three times with 14 chicks per replicate. Feed and water were supplied ad libitum during the experimental period. Four experimental diets were provided as follows: a. Basal diet without Vitamin E and any selenium sources, for the control group (control). b. Basal diet supplemented with 250 mg/kg Vitamin E for the treatment group 1 (Vit E). c. Basal diet supplemented with 250 mg/kg Vitamin E plus 0.2 mg/kg organic selenium for the treatment group 2 (Vit E+Or Se) d. Basal diet supplemented with 250 mg/kg Vitamin E, plus 0.2 mg/kg inorganic selenium for the treatment group 3 (Vit E+Inor Se). The experiment lasted 42 days At the end of the study, there was a difference (P<0.05) regarding body weight gain in the first (Vit E) and the second (Vit E+Or Se) treatment groups compared to the control group. Feed conversion ratio was more efficient (P<0.05) in the treatment group 2 (Vit E+Or Se) compared to the rest. Glutathione peroxidase activity in plasma (P<0.01), kidney (P<0.05), leg muscle (p<0.05), heart (P<0.01) and liver (P<0.01) elevated in all of the treatment groups compared to the control group. Liver glutathione peroxidase activity in the treatment group 2 (Vit E+Or Se) was higher than the rest. The results of this study indicated that, utilisation of organic selenium plus vitamin E in broiler diets was effective for improving the body weight gain, the feed conversion ratio, and plasma and tissue glutathione peroxidase activityKeywords : Broiler, glutathione peroxidase, performance, selenium, Vitamin E
