Badger Culling for Bovine TB: Welfare Evidence and Controversy

Badger culling to control bovine tuberculosis is one of the most contested wildlife management policies in the UK. Understanding the welfare and scientific evidence is essential for informed advocacy.

Key Facts

Badgers are a wildlife reservoir for bovine tuberculosis (bTB), a disease causing significant welfare harm to cattle and economic losses to farmers
The UK government has licensed culling of badgers in high-incidence bTB areas since 2013 — culling is conducted by shooting free-running badgers at night
Scientific debate continues about the contribution of badger-to-cattle transmission versus cattle-to-cattle transmission as primary drivers of bTB persistence
The Independent Scientific Group on Cattle TB (Krebs Report) concluded that "badger culling can make no meaningful contribution to the control of bTB in Britain" — a conclusion contested by government scientists
Perturbation — dispersal of surviving badgers from culled areas — may temporarily increase bTB spread as dispersed badgers contact new cattle herds
Badger vaccination using BADGERVAC has shown efficacy in field trials — a four-year vaccination programme can reduce bTB incidence in vaccinated badger populations
Wounded but unrecovered badgers — those injured but not killed by shooting — represent a significant welfare concern that is difficult to monitor in free-shooting operations

Welfare Considerations

Badger culling welfare involves two distinct animal populations: the badgers being killed, and the cattle affected by bTB. Badgers shot at night using free-shooting operations experience variable outcomes — quick death when shots are well-placed, but protracted suffering when animals are wounded but escape. Wound rates in culling operations have been estimated at 20-25% by independent monitors, representing a substantial welfare concern for a protected species being killed under licence. The welfare case for vaccination over culling is strong on badger welfare grounds alone: vaccination protects badgers without killing or injuring them. The case for vaccination versus culling on bTB control grounds is more contested, though the evidence base for culling effectiveness is weaker than government messaging suggests.

What You Can Do

Support the Badger Trust and Wildlife Trusts campaigns for badger vaccination programmes as a welfare-superior and potentially equally effective alternative to culling
Engage with your MP on the evidence base for badger culling policy and advocate for increased investment in cattle vaccination — currently in development — as the long-term solution
Donate to Badger Trust legal challenges to culling licences where culling methods do not meet welfare standards
Support independent monitoring of badger culling operations and transparent reporting of wound rates
Advocate for improved cattle biosecurity and movement testing as the primary bTB control strategy, reducing dependence on wildlife culling
Raise awareness of the contested scientific basis for badger culling — public understanding of the evidence quality matters for democratic accountability of the policy
Support wildlife-friendly farming practices that reduce badger-cattle contact rather than eliminating badger populations through culling
