The importance of the study of the chicken’s genital apparatus coincides from an economical point of view with the acquirement of one of the main avian products for which this bird is selected: the egg. In birds only the left ovary and oviduct are developed. The mature ovary has a grape-like shape, suspended form the ceiling of the abdominal cavity, immediately under the cranial extremity of the kidneys. The oviduct is long and flexuous, leading from the ovary to the cloacae. Material and Methods: The research was carried out on the ovaries and oviducts harvested from 15 chickens of various ages (56 to 126 days) that were dissected using common techniques in the Comparative Anatomy Laboratory of the FVM Cluj-Napoca. The samples were also histologically prepared and examined using regular optical microscopy. Results and Conclusion: Following the examinations, the have noticed that in the first group age, the ovary has a smooth surface, at 98 days, its surface becomes uneven, while at 126 days, it completes its development, acquiring its classical grape-like shape. The 56 days and 98 days old oviduct cannot be divided into segments; only the 126 days old oviducts displays macro and microscopic segmentation. In conclusion, results indicate that the ovary and oviduct of chickens reach maturity at the ages of 126 days, when the birds become ready to produce eggs.
