Clinical, laboratory, and morphological diagnosis of diseases in the oviducts and paraovarian structures of cows.

The objective of this research was to study the spread of diseases in the oviducts and paraovarian structures of cows diagnosed using clinical, laboratory, and morphological analysis methods. Rectal examinations of 283 cows were conducted on farms to study their reproductive function. A thorough morphological study of the reproductive organs was carried out and the ovaries and uterus were weighed and measured. The method to detect blockage of the oviducts involved filling the oviducts with air under excessive pressure and assessing the patency based on the pressure drop. During postmortem macroscopic examination of the reproductive organs of infertile cows, the most common diseases of the oviducts and pathology of paraovarian structures detected were hydrosalpinx (6.9%), cysts on oviduct walls (3.4%), ovarian-bursal adhesions (37.8%), cysts and adhesions in the mesovarian ligament and mesosalpinx (17.0%), cysts of the ovary network (3.4%), and serous inclusion cysts on the surface of the ovary (6.9%). Clinically pronounced pathology of the oviducts was detected in 2.5% of infertile cows. The proposed method for diagnosing obstruction of the oviducts made it possible to find the hidden pathology of these organs, which manifested itself in increased patency and relative and total obstruction.
