BVD (Bovine Viral Diarrhoea):

Bovine Viral Diarrhoea (BVD) is a disease of cattle that causes a wide range of cattle health problems such as abortion, infertility, respiratory and gut disorders among other problems. In 2010 Scotland embarked upon a BVD eradication programme which is successfully reducing the incidence of disease.

PI (Persistently Infected):

PIs shed large amounts of virus throughout their lives and are the main source of infection. BVD testing is crucial in controlling the disease as PIs often appear healthy. Watch the video and learn more about what makes an animal a PI or transiently infected with BVD

PI Locator:

The ScotEID webpage listing holdings (CPH) of all herds that have had BVD virus positive animals, i.e. transiently or persistently infected with BVD in the herd for more than 40 days.

'Risky’ Animals:

Include:

imported cattle from outwith Scotland
untested animals purchased from non-breeding herds
untested animals from a BVD (Not Negative herd)

These animals cannot leave the herd without an individual BVD Negative or Assumed Negative status. and must be BVD virus tested within 40 days of joining the herd.
