This study was designed to investigate the effects of vitamins A and E and Se supplementation on reproductive performance and some mineral parameters in ewes, and birth weight, growth and survival rates of their lambs. Four groups (A, B, C, D) were formed and fed a vitamin A and E and Se supplemented diet according to the following protocol. Group A (Control) was fed pasture + concentrate + trefoil hay, Group B (Vitamin A) was fed pasture + concentrate + trefoil hay + vitamin A (15000 IU/kg), Group C (vitamin A+E+Se) was fed pasture + concentrate + trefoil hay + vitamin A (15000 IU/kg), E (250 mg/kg), Se (0.3 mg/kg) and Group D (vitamin E+Se) was fed pasture + concentrate + trefoil hay + vitamin E (250 mg/kg), Se (0.3 mg/kg).
