ВЛИЯНИЕ ПАТОЛОГИЧЕСКИХ ИЗМЕНЕНИЙ ПРИ СКЛЕРОЗЕ ЯИЧНИКОВ НА МОРФОФУНКЦИОНАЛЬНЫЕ ПОКАЗАТЕЛИ ЯЙЦЕПРОВОДОВ У КОРОВ

Abstract

The article presents the research findings of the effect of pathological changes caused by ovarian sclerosis on the morphofunctional parameters of oviducts in cows. The primary reason for symptomatic infertility in cows is functional disorders of the ovaries. The epithelial tissue of the reproductive organs in animals plays a vital role in their reproductive function. Histological and morphological changes in a cow's uterus are closely connected to changes in the ovaries. Specifically, ovarian sclerosis can disrupt the functional activity of the uterine horn's epithelial cells. When studying the morphofunctional state of oviducts damaged by ovarian sclerosis in cows, we found histological and morphofunctional changes therein associated with changes in the ovaries. The left ovary was more often sclerotized than the right one. The total wall thickness of the left and right oviducts in the setting of ovarian sclerosis thickened compared to the norm. In this scenario, the submucosa in the left oviduct measures 22.3% below the standard thickness, whereas in the right one, it is notably thicker by 38.4%. The muscular layer of the left and right oviducts is thicker than norm by 38.7% and 104.2% respectively. The area of protoplasm and the nuclei of the surface epithelium in the left oviduct decreased by 12.95% and 22.2%, respectively, compared with the norm. The functional activity of the surface epithelium cells in the left oviduct damaged by ovarian sclerosis was lower than that in clinically healthy cows.
