Abstract :ABSTRACT This study was carried out to determine the effects of various levels of Se (seleno-methionine) and Vit E supplementation at various levels on body weight gain (BWG), feed consumption (FC), feed conversion ratio (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 (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 (0, 0.25, 0.50 ve 1.00 mg/kg Se) and Vit E (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 (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 (P<0.05). Dietary Se levels had a significant effect on liver weight (P<0.01), serum (P<0.05) and pancre-as (P<0.01) concentrations of Se.Keywords : Broyler, doku, performans, selenyum, Vit E.
