Horn Welfare in Cattle: Dehorning and Polled Genetics

Dehorning of cattle causes acute and chronic pain and is performed on millions of animals annually, while polled (naturally hornless) genetics offer a welfare-positive alternative that is increasingly available.

Key Facts

Approximately 60% of dairy cattle in the UK are dehorned or disbudded as calves
Disbudding with caustic paste or hot iron causes acute pain lasting hours to days
Local anaesthesia is required by UK law for disbudding over 2 weeks of age
NSAID analgesia significantly reduces post-procedure pain but is inconsistently used
Polled genetics for major dairy breeds are commercially available and are improving
Complete transition to polled cattle would eliminate the need for dehorning

Welfare Considerations

Disbudding without adequate analgesia causes acute severe pain that persists for 24-48 hours. Even with anaesthesia and NSAIDs, pain is not fully controlled. The routine nature of the procedure should not obscure its welfare impact: it is a painful procedure performed on millions of calves annually. Transition to polled genetics represents the only route to completely eliminating this welfare harm rather than merely reducing it.

What You Can Do

Support breed society development and promotion of polled genetics
Advocate for mandatory pain relief protocols for all dehorning and disbudding
Choose dairy products from farms committed to transitioning to polled herds
Support research demonstrating equivalence of polled and horned genetics for productivity
Donate to organisations promoting polled genetics as welfare improvement
Engage with farm assurance schemes to strengthen pain management and polled genetics requirements
