Leukemia is a chronic infectious viral disease of a tumor nature. The disease is widespread in different countries of the world and is relevant for most regions of the Russian Federation. The purpose of the work is to study the epizootic situation of leukemia in cattle in livestock farms of the Central Federal District of the Russian Federation. A complex epizootological method and evidence-based epizootology methods were used in the work. Objects of research are dysfunctional points, sick cattle. The paper presents a comparative analysis of the epizootic situation for the period 2012–2016. In the analyzed period, a total of 470 dysfunctional points for leukemia were identified, which amounted to 29.59 % of the total number of dysfunctional points in the Russian Federation and 62908 animals with leukemia were registered, which amounted to 36.90 % of the total number of diseased animals in Russia. Despite the decrease in the number of cattle infected with leukemia in five subjects, and the absence of animals that died from leukemia in all 18 subjects of the Central Federal District of the Russian Federation during 2012–2016, the epizootic situation of leukemia in the whole region remains quite tense, which is explained by the failure to comply with the basic requirements of the state veterinary service regarding sanitary anti-leukemia measures, according to the “Rules for the Prevention and Control of Leukemia of Large R gatogo cattle “ (1999.).
