Bovine Viral Diarrhoea

What is Bovine Viral Diarrhoea?

BVD is a viral disease that causes substantial losses on dairy and beef units due to reduced fertility. There are several effective licensed vaccines available in the UK which can be used for herd protection. However, it is important to remember that vaccines rarely offer the herd 100% protection so surveillance programs should be discussed with your farm vet to ensure that farm status is not compromised.

 

In an effort to eradicate this disease from farms across the UK there are some national schemes in place in Scotland, England, Wales and Northern Ireland - follow this link to read more about national schemes and how you can get involved.  National Milk Laboratories is an accredited laboratory for all of these schemes.

Prevention and management of BVD can involve:

  • General surveillance of bulk milks (dairy) and youngstock (beef and dairy) 
  • Vaccination
  • Tag and testing calves (including dead or dying)
  • Increased biosecurity between youngstock and adult groups
  • Double fencing boundaries between cattle farms
  • Safe disposal of aborted/stillborn calves

Options should always be discussed with the farm vet.

Individual milk tests can be performed on one milk sample through to a whole herd test. 

Bulk milk tests for BVD can be scheduled on an ad-hoc or quarterly basis.  No extra bulk sample necessary, the bulk samples held in the NML fridge can be used for testing. 
**Please note that the bulk milk antibody test can be affected by vaccine so it is important that if vaccinated herds are using this test option they monitor antibody levels quarterly to ensure the trend is level or falling.
