Prognosis of the epizootic process of cattle leucosis was based on the biological balance of the stock volume in the populations of the specific specie (via natural or artificial reproduction) as well as on the parameters of incidences and intensively of affected animals, established in various Belarusian farms. The main criteria of the prognosis are the initial level of incidences, initial and final stages of infection of the population within a year and the percent of the stock reproduction. The mathematical models considered characterize the epizootic process of cattle leucosis as a dynamically developing system with ups and downs, deviations in the parameters of incidences, intensity of infection, number of healthy and ill animals, number of incoming and disappearing animals
