Abstract :An attempt was made to determine the effects of selenium and vitamin E supplementation on thyroid hormones in lambs. Sixteen Akkaraman lambs were used and divided equally into four groups. One group was used as a control. Second group was fed with selenium insert ignore into journalissuearticles values(sodium selenite, 0.3 mg kg -1 feed);. Third group was fed with vitamin E insert ignore into journalissuearticles values(DL-a tocopheryl acetate, 250 mg -1 feed); and fourth group was fed with selenium insert ignore into journalissuearticles values(sodium selenite, 0.3 mg/ kg -1 feed); + vitamin E insert ignore into journalissuearticles values(DL-a tocopheryl acetate, 250 mg kg -1 feed); supplemented diet. Serum selenium, vitamin E and plasma thyroxine insert ignore into journalissuearticles values(T 4 ); and tri-ioda-thronine insert ignore into journalissuearticles values(T3); were measured at Ist, 5th, 10th weeks. Levels of T3 were slightly increased and both levels of T4 and ratio of T4/ T3 were slightly decreased when vitamin E, selenium and vitamin E plus selenium were supplemented to the diets of lambs. The levels of serum vitamin E were significantly higher insert ignore into journalissuearticles values(p
