A total of 42 weeks old 198 Cobb 500 birds were randomly assigned to 18 deep litter pens (10 females and 1 male per pen) and were supplemented for two months of period. Broiler breeders were randomly assigned to three treatments and six replicates. The control group (T0) received only water. The birds from treatment 1 (T1) and treatment 2 (T2) were supplemented with 10 mg L-1 pure vitamin E and 50 mg/1 L Selenium with vitamin E. The lowest (p < 0.05) hatchability (77%) was recorded from T0 treatment and the highest (p < 0.05) hatchability (88%) was recorded from T1 treatment .The lowest (p < 0.05) fertility (86%) was recorded from T0 treatment and highest (p < 0.05) fertility (93%) was recorded from Ti treatment. The lowest (p < 0.05) growth performance (87%) was recorded from To treatment and the highest (p < 0.05) growth performance (98%) was recorded from T1 treatment. There were no significant differences of total egg production, weekly average feed conversion ratio and weekly average weight gain of broiler breeders between three dietary treatments (p > 0.05). In conclusion the hatchability, fertility and performance of broilers were increased by dietary supplementation on said amount of selenium supplementation (50 mg L-1) than pure vitamin E (10 mg L-1).enAnimal SciencesAgricultureAnimal ProductionAnimal Production TechnologyOther
