Abstract
The current study was conducted to detect the pathological conditions of the congenital abnormalities of ovaries and uterine tubes of cows slaughtered at the abattoir in Sulaimani, Kurdistan Region-Iraq. The pathological conditions were subjected to a macroscopic and microscopic examination of 404 samples of female genitalia collected from slaughtered non-pregnant cows, during the period from February to September 2014 from the Qaragol slaughterhouse twice a week. The organs were observed macroscopically for pathological abnormalities and stained tissues with Haematoxylin and eosin. They were examined under microscope for determination of the type of lesion present in the organ. Among the 404 genitalia samples collected from the non-pregnant animals, 206 (51%) were found without gross pathological abnormalities and (with cyclic activity) and the 30 (7.43%) samples were found with gross congenital abnormalities of ovaries and uterine tubes. Detected lesions in the ovaries and uterine tubes included paraovarian cysts 3.21%, ovarian hypoplasia 1.98%, ovarian agenesis 0.50%, aplasia of uterine tube 0.99%, segmental aplasia of uterine tube 0.50% and accessory of uterine tube 0.25%. The histopathological sections of paraovarian cyst showed a single layer of tubal-type ciliated cuboidal epithelial cells resting on a thin layer of fibrous tissue, the section of ovarian hypoplasia showed lack of ovarian follicles and oocytes, which instead are replaced by bands fibrovascular stroma. The partial duplication of uterine tube was observed, which was about 6 cm from the uterotubal junction and extended distally for a distance of 4 cm that was found in right side of tracts. It was concluded that the paraovarian cysts were the most common congenital abnormalities of ovaries and uterine tubes in non-pregnant cows.
