Infection with BVD virus causes suppression of the immune system and can cause symptoms in multiple body systems. It affects reproduction and the unborn calf, and contributes to outbreaks of diseases such as pneumonia and scours (diarrhoea). A Persistently Infected (PI) calf can develop fatal Mucosal Disease.

Why participate

  • Costs resulting from the disease often go unrecognised as symptoms resemble common problems. In the Netherlands costs are estimated at between 21 and 412 euro per cow per year.
  • Persistently Infected cattle cannot be cured and will cause widespread infection.
  • Eradication will be cost-effective in any farm situation. 

What sampling is involved

  • Initial bulk tank milk scanning for BVD virus and BVD antibodies. In young stock this means antibody screening by blood sampling (QuickScan BVD): a combination of tests to indicate the status of your herd and the possible presence of PI calves. QuickScan BVD consists of RT-PCR on Bulk milk/ Ab-ELISA on Bulk milk/Ab-ELISA on blood of non- vaccinated animals aged 8-12 months.
  • Depending on the outcome, a farm can participate in a programme (4 routes possible) to become BVD-free.
  • Once a farm has eradicated BVD it will participate in a monitoring programme to maintain its BVD-free status

How you get advised

  • GD experts advise whether a custom QuickScan BVD is needed on your farm.
  • With these results, we will advise you on which of the 4 different routes to a BVD-free status is most suitable.
  • After eradication, your farm will be monitored and you will be supported to maintain a high BVD status. If your farm faces a new BVD infection, we will run a detection programme to re-establish your BVD-free status
