| Abstract : (567) fertilized eggs for Japanese quail Coturnix japonica were incubated in automatic incubator and injected (324) eggs from it into chorio-allantois membrane on the 7th embryo age by (0.1) ml of 1 and 1.5% vitamin E solution which had divided on 2 treatments (T2,T3) respectively and divided from it (T4,T5) respectively during eggs production season , on the other hand (243 ) remained eggs didn't inject and considered as control treatment (T1) and divided from it (T6,T7) during eggs production season .(T1,T2 and T3) were included on (9,6 and 6) replications respectively (27 eggs per replication),at hatching the raising (420) chicks according to divided treatments until the sexual maturity (6 weeks) after then the females were sorted only. The experiment was started at (8 weeks) for (3 months) by using (252) females were distributed on 7 treatments (T1: females of control group, T2 and T3: females that produced from in ovo injection by 1 and 1.5 % vitamin E respectively ,T4 and T5: females that produced from in ovo injection by 1 and 1.5 % vitamin E with addition in drinking water by 150 and 300 mg/liter respectively ,T6 and T7: females that produced from without in ovo injection by vitamin E with addition in drinking water by 150 and 300 mg/liter respectively) ,every treatment was included on (3) replications (12 females per replication) to study some productive traits of Japanese quail females. The results were revealed that take placing significant increase(p<0.05) in total mean for vitamin E treatments (T2,T3,T4,T5,T6 and T7) in mean of egg production (H.D) and in mean of egg weight ,significant decrease (p<0.05) in mortality perentage (%) and also in feed consumption with exception (T2),highly significant decrease (p<0.01) in feed conversion coefficient with exception (T2),dominance of (T5,T4) then (T3, T7 and T6) and then (T2) on (T1) in productive traits of females with generally dominance for all vitamin E treatments in most periods of experiment. | ||
