Bovine Viral Diarrhoea (BVD) causes reproductive failure, immunosuppression, and death in cattle. National eradication programmes in Scandinavia and Scotland have demonstrated major welfare benefits.
BVD causes enormous welfare suffering through reproductive losses, immunosuppressed animals susceptible to multiple diseases, and persistently infected calves born with neurological problems. National eradication programmes have demonstrated that sustained systematic effort can eliminate the disease and the welfare suffering it causes.
