| Abstract | ||
| The aim of this study was to investigate the effect of estradiol injection in The productive performance of female Japanese Quail in various stages of production . The study was carried on for the period 3112014 until 3112015 for 2-13 weeks old by using 216 hens randomly distributed on six treatment each one has three replicates. The results showed that experience periods of hormone estradiol has improved significantly from body weight and the weight increase (p<0.05) had no significant effect hormone estradiol in feed consumption, with a significant improvement in feed conversion ratio (p<0.05) Estradiol showed significant superior weights in females at maturity (p<0.05), results showed significant improvement (p<0.05) in egg production Got high moral improvement (p <0.01) for adjective Cumulative egg production and egg weight, and significant improvement (p<0.05) In the egg mass and the coefficient of food conversion, of specific traits of eggs happened significantly improved Treatments of estradiol injection (p<0.05) represented by weight and shell thickness, Haugh unit and yolk index. it got a significant increase (p<0.05) in the concentrations of hormone, in the treatments of estradiol injection in comparison with the two control treatment | ||
