What is BVD?

What is Bovine Viral Diarrhoea?

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
