The current investigation was performed on 30 healthy slaughtered female turkey, the samples were processed for the histo-morphological examination.Whereas ovaries were dissected after catched and slaughtered birds directly. The morphological findings showed that, the ovaries of immature (6 months) and mature (one year) ages of turkey were located in the Coelomic cavity with pale to dark yellow color and irregular shapes resemble a bunch of grapes due to different sized follicles on its surface., at six months of age, the ovary was composed of an outer cortex and inner vascular medulla, there was a clear separation between them. The cortex enclosed ovarian follicles of different sizes. In addition, there were some large vacuolated cells known as thecal gland. Some small secondary follicles had vacuoles that resemble pre-antral follicles in primates and other birds. The ovarian medulla represented the inner vascular part of the ovary. At one year of age, the ovarian follicles showed an advanced stage of growth. The large growing follicles migrated to the ovarian surface and the covering ovarian epithelium became thinner. Postovulatory regressed follicle that resembles corpus luteum was observed. At six months: highly connective tissue fibers presented as collagen, elastic, reticular. Whereas connective tissue decreased at one year of age, so the age of laying and maturation in turkey is nearly at one year of age. This study showed the ovary of female turkey at one year of age contained ovarian follicles at advanced stage of growth and Postovulatory regressed follicle that resembles corpus luteum. So, the age of laying and maturation in turkey is nearly at one year of age.
