BVD (bovine viral diarrhoea) is one of the most common and costly diseases in New Zealand cattle.
In New Zealand, about 15%-20% of dairy herds and 65% of beef herds are infected with BVD virus. Around 80% of New Zealand dairy and beef herds have had exposure to BVD virus at some point in time.
BVD has been shown to cause scouring and ill thrift in young cattle. In adult cattle, BVD is associated with reproductive losses, reduced milk production and elevated milk somatic cell count.
The effects of BVD virus on fertility and on the unborn calf are profound, including low in calf rates, abortion, stillbirths, birth of “dummy calves” and the birth of persistently infected (PI) carriers of BVD virus. PI cattle are responsible for the maintenance of BVD virus infections and managing PIs is critical to BVD control.

CONTROLLING BOVINE VIRAL DIARRHOEA (BVD)
Control of BVD has never been simpler. Thanks to new lab tests and effective BVD vaccination, BVD programmes can be easily set up to control and eradicate BVD on your farm.
TOOLS TO CONTROL BVD INCLUDE:
Testing and culling to:
Determine your herd’s current BVD disease status
Identify PI cattle for culling
Diagnose and correct a breakdown in control early, to minimise any harm
It is essential to protect your herd from the introduction of the virus. Measures include:
Testing all new stock coming onto the farm, e.g. service bulls and herd replacements
Improving fencing where necessary to prevent introduction from neighbouring cattle
Biosecurity without vaccination can be difficult and costly to achieve. Vaccination with Ultravac® BVD offers reliable insurance against PI’s and BVD losses.
Vaccination with Ultravac BVD is recommended to:
Prevent disease in young stock, calves are generally vaccinated from 3 months of age
Protect breeding stock by annual revaccination
Prevent foetal infection and the birth of PI’s (Persistently Infected or carrier calves)
