Abstract
Bovine enzootic leukemia (EBLV) remains an acute problem for animal husbandry in many regions of Russia. Based on this, the goal was set: to study the epizootic situation of bovine leukemia in the Republic of Dagestan. The material for the study was taken from the official source of the Veterinary Committee of the Republic, as well as supplemented with our own serological blood tests for bovine leukemia virus (bovine leukemia). Laboratory tests for the detection of antibodies to BLV in RID were carried out according to the "Guidelines for the diagnosis of bovine leukemia" (2000). Research results: the spread of BLV has been established in some municipal districts and urban districts throughout the republic. In 2023, from all veterinary laboratories (stations), serological studies were conducted in the amount of 1101,689 animal blood samples for BLV. Of the animals studied, antibodies to the BLV antigen in RID were obtained in 2,778 (0.25%) samples. A high percentage of animal HCV infection was detected in the following districts and cities: Kizlyarsky – 2% (388), Tlaratinsky – 1.3% (341), Botlikhsky – 1.2% (450), Babayurt – 1.1% (188), Gunibsky – 0.8% (228) and in Makhachkala – 0.9% (180). In 16 districts and in Khasavyurt, the percentage of infection of animals with BLV was at the level of 0.3% or lower. We obtained 440 animal blood samples from sample farms, which were examined in the RID. 37 (8.4%) animal blood samples gave a positive result for BLV. Thus, the general epizootic situation in EBLV remains relevant, but the prevalence of BLV among animals is decreasing in the republic.
