Abstract: Broiler breeders were allocated at random to one of seven experimental diets containing graded levels of supplementary vitamin E (0, 20, 40, 60, 80, 100 and 120 IU kg-1 diet) between 26-35 weeks of age. Egg production, egg weight, fertility, livability and hatchability (30 and 35 weeks of age) were not influenced by the level of vitamin E in the breeder diet. But birds receiving 40 IU of vitamin E kg-1 diet had higher hatchability of fertile eggs compared to 0 and 20 IU of vitamin E kg-1 groups at 35 weeks of age (90.79 vs. 85.09 and 86.60%, respectively). Dietary levels of vitamin E did not affect antibody titer (IgG) against Newcastle disease virus at 35 weeks of age. Antibody titer of day old chicks from hens receiving 60 IU of vitamin E kg-1 were higher (p≤0.05) than chicks from hens fed 0 and 20 IU of vitamin E. At 35 weeks of age (not at 31 weeks of age), Hugh units of eggs were higher (p≤0.05) in hens fed 40, 60, 80, 100 and 120 IU of vitamin E kg-1 compared to 0 IU of vitamin E kg-1 (87.06, 92.21, 93.89, 93.25, 94.61 and 93.09, respectively). Age had negative effect on Hugh units of eggs (p≤0.01). The results of this experiment suggest that the vitamin E requirement of broiler breeders for persisting of hatchability may be 40 IU kg-1 and for maximizing passive transfer of antibody from breeder to progeny may be higher.
