Effect of Supplementation Different Levels of Vitamin E and Pumpkin Seed Oil to the Diet on Productive, Physiological and Reproductive Performance of Japanese Quail

Abstract

The principal goal of this study was to evaluate whether dietary vitamin E  and pumpkin seed oil would affect  the productive, physiological and reproductive performance of Japanese quail by using 120 birds at 22 weeks of age. The birds were randomly distribution into five dietary groups 24 birds each group contain three replicated pens, as follow: First group: kept on basal diet without any addition as control group, second and third groups were fed the basal diet supplemented with 150  and 200 mg/ kg vitamin E / kg of diet, fourth and fifth groups were fed the basal diet supplemented with 15 and 30 ml/kg pumpkin seed oil /kg of diet respectively. The results showed a significant improvement in egg production (H.D%), egg number, egg weight and egg mass produced for the vitamin E (200mg/ kg of diet) compared with the other groups. Additionally, the results showed that vitamin E (200mg/ kg of diet) significantly increased gonads relative weight , testes development,  egg characterizes and serum testosterone, estrogen, FSH and LH hormones compared with other groups. Also , the birds were fed on 15 and 30 ml seed pumpkin oil/ kg of diet were significantly increased in the most parameter compared with control group. It can be concluded that the addition of vitamin E (200 mg/kg of diet) and pumpkin seed oil (30ml of diet), had positive effects on gonads, testicular histology, egg production and serum testosterone, estrogen, FSH and LH hormones concentration.
