تأثير المجموعة الوراثية و مصدر دهن العليقة في الأداء الإنتاجي لأمهات طائر السلوى

Abstract EN

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.
