A total of, 126 laying hens (20 weeks of age) were distrubuted randomly to seven dietary treatments Each treatment included three replicate pen (6 hen/pen) and were fed one of the following diet : (T1) treatment one (Control) which represent comparison diatery that free from Omega-3 source, T2 and T3 were supple mented with 1, 0.5 % flaxseed oil, T4 and T5 were added with 1, 0.5% fish oil and T6 and T7 were provided with 0.5, 1% walnut oil. Results revealed that there are no significant differences between treatments in the averge of egg production, cumulative egg number, feed conversion ratio. Significant differences were observed among treatments in the average of egg weight. The treatments T2, T3, T6 and T7 were showed superior as compared with the others. On the other hand, the mean average of egg masswas showed superiority in the T3, T4, T6 and T7 treatments in comparison to other.
