Abstract
This study was conducted to evaluate the productive performance (Production period) of three genetic groups different with feather color White , Black and Desert when fed three diets with 3% from different oil sources compared with control diet (T1) namely: sunflower oil (T2) , vegetable fat (T3) and animal grease (T4). Two hundred fifty two females , each genetic group 84 females of 7 weeks age were used and distributed randomly to four treatments with 3 replicates per each treatment and every replicate had 7 females. The birds were reared in cages to 12 weeks (the data of first 2 wks. Were as a preliminary period) with ad-libitum feeding. The results revealed that the genetic group with white feather had a significant effect in : average egg number , egg production H.D. , feed consumption , shell with membranes weight and yolk diameter , While the desert birds showed higher live body weight. Also, the oil source had significant effect on the performance as the sunflower oil diet showed a significant effect in: live body weight , average egg number , egg production H.D. , feed consumption , feed conversion and albumen weight. While , there were no significant effect on egg weight. The interaction between genetic group and oil source showed significant effect on all production traits except egg weight.
