General Information

What is BVD?

BVD is a viral disease of cattle caused by BVD virus. Infection can result in a wide range of clinical signs including:

  • Reproductive problems, including failure to conceive, abortion and birth defects
  • Calves that survive infection during early pregnancy are born persistently infected (PI) with the virus
  • PI cattle may develop a fatal condition called mucosal disease
  • Most PI cattle die before 2 years of age- either from mucosal disease or other illnesses
  • Weakening of the immune system, leaving cattle more susceptible to other infections, particularly scours and pneumonia in calves
