RESUMO
This work was conducted to study the effect of feeding diets containing 2-4% over and unheated oil with or without vitamin E supplementation on growth and reproductive performance of Japanese quail. A total of 288 one-day old Japanese quail were allotted into 9 groups. Quail of group 1 were fed on basal diet [BD] without any supplementation. Quail of groups 2 and 3 were fed on BD containing 2 and 4$ unheated oil. Quail of groups 4 and 5 fed the BD containing 2 and 4% over-heated oil. Quail of groups 6, 7, 8 and 9 were fed as groups 2, 3, 4 and 5, respectively, in addition to vitamin E supplementation [6 mg/kg diet during starting and growing periods and 12 mg/kg diet during the laying period]. From the results it was concluded that, the addition of 4% unheated oil and vitamin E to the used diet of quail improves their growth and reproductive performance
