The results showed significant improvement in T3,T4 and T5 as compared with T2 and T1 (control) in most productive parameters included hen day egg production, egg weight, egg mass and feed conversion ratio. As well as significant improvement in live body weight for T1, T3, T4 and T5 over T2. No significant differences among treatments were found in feed intake during all production periods.
