Abstract :ABSTRACT This study was carried out to determine the effects of various levels of Se insert ignore into journalissuearticles values(seleno-methionine); and Vit E supplementation at various levels on body weight gain insert ignore into journalissuearticles values(BWG);, feed consumption insert ignore into journalissuearticles values(FC);, feed conversion ratio insert ignore into journalissuearticles values(FCR);, carcass characteristics and serum, liver and pancreas concentrations of Se in broilers. A total of 360 1-d-old Ross-208 broiler chicks were divided into twelve groups of 30 birds. In this study, a starter diet containing 21% crude protein insert ignore into journalissuearticles values(CP);, 3006 kcal ME/kg and 0.13 mg/kg Se and a grower diet containing 19% CP, 3196 kcal ME/kg and 0.12 mg/kg Se were used. The chicks were fed either starter or grower diets supplemented with seleno-methionine insert ignore into journalissuearticles values(0, 0.25, 0.50 ve 1.00 mg/kg Se); and Vit E insert ignore into journalissuearticles values(0, 200 ve 400 IU/kg); for 42 days. Feed were given as ad libitum during the experiment. Dietary Se, Vit E levels and S*E interactions produced no signifi-cant effect on BWG, except for 2nd week, in the experiment. Ration S*E interactions had a significant effect on FC at the 2nd week insert ignore into journalissuearticles values(P 0.05);. But, dietary Se levels had a significant effect on rump weight, at the same time carcass, rump and breast+back weights were effected by dietary S*E inter-actions significantly insert ignore into journalissuearticles values(P<0.05);. Dietary Se levels had a significant effect on liver weight insert ignore into journalissuearticles values(P<0.01);, serum insert ignore into journalissuearticles values(P<0.05); and pancre-as insert ignore into journalissuearticles values(P<0.01); concentrations of Se.
