The article presents the main methods of diagnosis and control of the bovine leukemia virus currently used. The wide spread of the disease is due to a fairly easy transmission of the virus, the lack of early diagnosis, vaccination and treatment. Therefore, the problem of the spread of leukemia virus in cattle is very acute and is a pressing issue in animal husbandry, which requires a speedy solution. The purpose of the work was to improve the herd of cattle from leukemia virus through a set of measures. The studies were conducted in the peasant farm individual entrepreneur V.D. Zinchenko of the Kemerovo region on the black-and-white cattle. Measures to combat VLKRS consisted in the identification of sick and infected animals during routine diagnostic studies and their further exclusion from the herd. The results of the study showed a positive trend in the release of the herd from leukemia virus. Separate content of RID + animals, isolated breeding of heifers (from the number of offspring from sick and infected cows) for their phased replacement and further inclusion in a healthy herd, gives a significant reduction in the number of virus carriers and sick animals.
