Overview of BVD (bovine viral diarrhoea) welfare significance and national eradication progress.
BVD eradication is a welfare programme with significant benefits for cattle populations. BVD causes reproductive failure, neonatal mortality, immunosuppression, and direct disease welfare harm. Persistently infected cattle shed virus continuously, compromising the welfare of herd-mates. National eradication programmes achieve welfare benefits at population scale that individual farm efforts cannot. Scotland's achievement of BVD-free status demonstrates what is achievable through coordinated national action.
