Nosological Features of Infectious Abortions in Cows

Abstract

Providing the country's population with high-quality products is a priority task of modern animal husbandry. However, there are a number of problems in the industry that prevent obtaining quality products of animal origin in the required volume. The intensification of dairy farming and the increase in milk productivity of cows is often accompanied by a metabolic disorder, which reduces the body's resistance, contributing to the development of immune-deficiencies, which increase the susceptibility of animals to infectious diseases, some of which have an abortive form of manifestation and, accordingly, the consequence is a lack of offspring and potential income due to abortions. Abortion in cows should be considered not only as a gynecological problem, but also as an economic one, because animal husbandry accounts for more than 38% in the structure of gross agricultural products of the country and the lack of keeping of young animals significantly affects the development of the livestock industry. This publication is devoted to the results of the nosological profile of infectious abortions in cows on the territory of Ukraine, among which 64% of cases are infectious agents - 41.4% of bacterial origin and 22.6% of viral origin. The most frequent factors of bacterial etiology of abortions in cows are leptospira, coxiella, salmonella, mycoplasma, campylobacter, chlamydia, toxoplasma and listeria, and the most common viral ones are flavo-virus, gamma-herpesvirus and alpha-herpesvirus.
