Total means of egg weight and yolk diameter (Tables 2 and 3) showed a significant effect (p < 0.01) of feeding flax seed, with treated hens produced the heaviest eggs and highest yolk diameter when compared to control hens.
Dietary flax seed at levels of 2 % (T1) and 4 % (T2) did not differ significantly from control group as regards total means of yolk height, although there was clear trend for this trait to be higher in T1 and T2 as compared with control group (Table 4). However, T3 group surpasses C group with relation to this trait, while there were no significant differences among T1, T2, and T3 groups.
The effect of inclusion flax seed into the quail diet on yolk weight was presented in Table 5. The date obtained showed that total means of yolk weight of quail groups received diet supplemented with flax seed at levels of 4 % (T2) and 6 % (T3) were higher (p < 0.01) with
