Badgers, Bovine TB, and Welfare: Science, Culling, and Alternatives 2025

Keywords: badger welfare, bovine TB, badger culling, vaccination, bTB wildlife

The management of bovine tuberculosis (bTB) in the UK and Ireland has created one of the most contentious wildlife welfare debates in Europe. Badgers (Meles meles) are a wildlife reservoir of Mycobacterium bovis, and badger culling has been deployed as a bTB control measure in England since 2013. Welfare concerns with culling include the use of cage trapping followed by shooting, free shooting (with wounding rates estimated at 7-25%), and the stress of prolonged trap confinement. Scientific evidence on culling effectiveness is disputed: the Krebs trial found culling reduced cattle bTB by 19-28% in culled areas but increased it in surrounding zones (perturbation effect). Vaccination with BCG is an effective and welfare-positive alternative, reducing bTB prevalence in vaccinated badger populations by 70-74%. England introduced injectable BCG vaccination programmes alongside culling from 2019. An oral bait vaccine (BCG in fishmeal bait) under development would eliminate capture welfare issues entirely.
