Dr. Umesh Gaur, Kiran Singh

Abstract: In view of the changed observed in photoperiodic response system (PRS) of the birds it is aimed in the present investigation, to validate the effect of climatic factors under the influence of hormonal treatment. The investigation was carried out using female hormone (Estradiol Benzoate commercial available as estradiol).The hormone treatment is given in different doses as describe earlier using photosensitive, photostimulated and photo refractory birds.
