Analysis of infection and incidence of leukemia in cattle

Abstract

This article analyzes the epizootic situation of leukemia of beef and dairy cattle in the farms of the Smolensk region. Laboratory diagnostic blood tests, which revealed infected and sick animals over certain years, played an important role in the study of the epizootic situation.
Along with this, we have studied the manifestation of the epizootic process of bovine leukemia in the Smolensk region. All this was later used to carry out effective work on the prevention and control of bovine leukemia.
The analysis data given in this article allow us to conclude that the disease of bovine leukemia in the region is gradually decreasing, and from 2017 to 2020 there is a more active decline. The most favorable epizootic situation for leukemia is in breeding and commodity farms for the cultivation of cattle. At the same time, the veterinary service is actively working to eliminate leukemia among cattle belonging to the population. Diagnostic studies on hematology to identify sick animals with leukemia have declined markedly, especially in recent years. This is due to both a decrease in the number of livestock and the elimination of the disease in many farms.
The livestock of cattle is annually subjected to routine serological studies, while the discharge of infected animals is still noted. As a result, there is a source of infection in the territory of the region among animals susceptible to it and the epizootic situation for leukemia among cattle remains unfavorable.
