Antiepizootic measures for bovine leukemia in farms of the Smolensk region

Abstract

Currently, diagnostics of infected animals is carried out by several methods: immunodiffusion reaction (RID), enzymelinked immunosorbent assay (ELISA), polymerase chain reaction (PCR), hematological, clinical, pathomorphological studies and bioassays. The effectiveness of antiepizootic measures carried out in the region's farms is in direct proportion to the volume and scale, on which the epizootic situation of leukemia depends. The article describes anti-epizootic measures carried out among beef and dairy cattle in the farms of the region. Based on the results of serological studies for 2019, a map-scheme was compiled, which reflects all the territories where animals infected with the leukemia virus, patients with leukemia and disadvantaged points were identified. The map clearly shows the spread of leukemia separately by administrative districts and in the whole region. The epizootic situation of bovine leukemia on the territory of the Smolensk region among livestock in farms of all forms of ownership was determined.

To determine the epizootic situation, a full analysis of veterinary and laboratory reports for 2019 and previous years was carried out. In comparison, we used the results of research and a schematic map for 2016.

The work carried out helped to study and compare the epizootic situation, the development of the epizootic process, the effectiveness of previous and current measures, to study the experience of improving the health of disadvantaged areas, to establish the causes of repeated infection of livestock leukemia in previously healthy farms.

The analysis of the epizootic situation and anti-epizootic measures for bovine leukemia in the Smolensk region was carried out in order to study the epizootic process and to properly organize work on improving farms from leukemia.
