MORPHOFUNCTIONAL CHARACTERISTICS OF THE OVIDUCTS IN COWS WITH OVARIAN HYPOFUNCTION

Abstract

This article presents the results of a morphofunctional analysis of the egg ducts of cows suffering from ovarian hypofunction. Based on a comprehensive study, including morphological, histological and cytometric methods, it was found that when ovarian function is impaired, the walls of both ovaries thicken compared to normal parameters. At the same time, there is an increase in the area of cytoplasm and epithelial cell nuclei in the left oviduct, while in the right one there is a decrease. In general, the wall thickness of the left and right egg ducts increases by 51.87% and 89.6%, respectively, compared with similar parameters in clinically healthy animals. The mucous layer of the left and right oviduct is thickened by 90.9% and 64.7% compared to the norm. With hypofunction of the ovaries in cows, the area of cytoplasm and nuclei of epithelial cells of the integumentary epithelium in the left oviduct decreases by 1.94% and 16.97%, respectively, compared with similar indicators in clinically healthy animals. This is accompanied by a decrease in the functional activity of cells by 13.5%. At the same time, in the right oviduct, on the contrary, the cytoplasmic area increases by 22.5%, while the area of the nuclei decreases by 30.8%. At the same time, there is an increase in the functional activity of epithelial cells by 39.1%.
