EPIZOOTIC SITUATION ON BOVINE PARASITOSIS IN THE KALUGA REGION

The studies of the epizootic situation on parasitosis in cattle on a cattle farm in the Kaluga Region showed the infection in animals of different ages. The calves under 30 days of age were infected with Cryptosporidia, and the calves under 6 months of age were infected with Cryptosporidia, Eimeria, Buxtonella and gastrointestinal Strongylata. In young animals under one and two years of age, invasion of the digestive tract with Eimeria, Buxtonella and Strongylata was found. The cows and heifers were infected with Eimeria, Buxtonella, gastrointestinal Strongylata, Dicrocelia and Fasciola. In scrapings from the cage floors where calves under 6 months of age were kept, and the passage floors, Buxtonella cysts, Eimeria oocysts and gastrointestinal Strongylata eggs were isolated. In the premises for keeping young animals under 1 and 2 years old as well as heifers and cows, scrapings from the floors of stalls and passages were found to have Eimeria oocysts, Buxtonella cysts, gastrointestinal Strongylata eggs and Dicrocelia eggs. On the studied cattle farm, the epizootic process associated with parasitic protozoa, Eimeria, Cryptosporidia, Buxtonella and gastrointestinal Strongylata, is permanent due to the presence of all components of this process: the invasion source, transmission factors and susceptible animals.
