Pestivirus

Pestivirus (also known as BVDV – bovine viral diarrhoea virus) causes abortion, ill thrift in young animals, diarrhoea and respiratory disease.

Pestivirus is widespread throughout the Australian cattle population. About 70% of herds are actively infected with the virus. Infection of susceptible animals can cause a variety of diseases, some not apparent until well after the initial spread of the virus in a herd.

Clinical signs that would lead a producer to suspect pestivirus include:

  • Early-term abortion or embryonic loss.
  • Temporary infertility.
  • Increased susceptibility to other diseases.
  • Weak, stunted or deformed calves.
  • Diarrhoea.
  • Respiratory disease.
  • Ill-thrift and wastage

There is an AgFact here, which lists various methods of control, including an annual vaccination (expensive) program.

Information on the required vaccination programme can be seen here
