Bovine leukemia remains one of the most urgent viral diseases in veterinary medicine, and potentially dangerous for humans. The strategy of combating it is aimed at improving the existing measures and full recovery of agricultural enterprises. The quality of animal products is a priority in the field of food safety. The aim of the research was to develop effective antileukemic measures for the improvement of livestock farms in the Belgorod and Kemerovo regions. The proposed antileukemic measures are to increase the frequency of serological studies from 6-th months to the 2-3th months among animals in areas with poor leukemia in cattle, as well as to increase the sensitivity of immunodiffusion test (AGID) due to highly centrifigation of the tested samples and an increase in the temperature of incubation samples close to the physiological norm for animals. The improved technique of staging an immunodiffusion reaction (AGID) allows detecting an average of 12% more infected animals with BLV in comparison with the approved method of staging a serological reaction AGID. Intensive introduction of PCR diagnostics to identify the causative agent of bovine leukemia in young calves, after the neonatal age period, will allow detecting early infection of animals and adjusting the program of antileukemia measures in disadvantaged farms. The introduction of PCR diagnostics in calves in the postnatal period of development in permanently dysfunctional livestock farms will contribute to the recovery of young animals from cattle leukemia in dysfunctional farms. The proposed antileukemia measures for the improvement of livestock farms in the Belgorod and Kemerovo regions made it possible to develop effective preventive measures for disadvantaged farms, improving the epizootic situation in the regions. So, in 2021, it was possible to completely improve the permanently dysfunctional economy of the LLC « Pobeda» in the Belgorod region.
