Abstract

The article presents the material on the study of clinical and morphological indicators of endometrial glandular-cystic hyperplasia in cows. It has been established that the share of endometrial hyperplasia glandulocystica in cows accounts for 11.4% of the total number of chronic uterine diseases. Most often, this pathology is diagnosed in cows 120 or more days after calving with an annual milk production of 6000-7000 kg. Glandular-cystic hyperplasia of the endometrium is most typical of the animals of the Red-Motley and Simmental breeds with loose keeping. Endometrial hyperplasia glandulocystica is characterized by a thickening of the uterine wall up to 6.5±0.28 mm, the presence of a cavity in the uterine horns of 3.4±0.19 mm, follicular cysts in the ovaries with a diameter of 42.5±2.8 mm. Endometrial hyperplasia glandulocystica is characterized by an increase in the height of the cells of the covering epithelium up to the height of prismatic one, growth of the uterine glands with the expansion of their lumens, an increase in height and vacuolization of the glandular epithelium. In case of glandular-cystic hyperplasia, uterine glands account for 28.6%, blood vessels – 12.3%, covering epithelium – 5.7%, which is by 1.88-1.97 times more, compared to clinically healthy animals. The height of the cells of the covering epithelium in case of this pathology is higher by 13.1%, the height of the epithelial cells of the uterine glands – by 23.4%, the thickness of the endometrium – by 1.38 times, which indicates endometrial hypertrophy.
