Bovine diarrhea virus (BDV) is a highly contagious viral disease of cattle characterized by damage to the gastrointestinal tract. The causative agent of VDK is an RNA virus from the Flaviviridae family.
The virus is transmitted by the fecal-oral route through infected food, water, and care items. Cows of all ages and sires are susceptible to VDK. The incubation period ranges from 2 to 8 days.
The main clinical signs of VDK are: diarrhea of varying severity, decreased appetite and productivity. Cows experience miscarriages and the birth of non-viable young animals. Mortality in the acute form of VDK can reach 90%.
The diagnosis is made based on clinical signs and laboratory results. Treatment is symptomatic. For specific prevention of VDK, inactivated vaccines are used. Nonspecific prevention includes veterinary and sanitary measures.
