Cattle Dehorning Welfare: 2025 Evidence and Practice

A 2025 welfare evidence update on cattle dehorning and disbudding, including pain management requirements, polled genetics alternatives, and regulatory progress.

Key Facts

Dehorning and disbudding cause significant acute and chronic pain in cattle — unanaesthetized dehorning is among the most painful routine husbandry procedures in livestock farming.
Disbudding (destroying the horn bud in calves under 2 months) is less painful and heals faster than dehorning mature cattle — early disbudding with appropriate analgesia is current best practice.
Local anaesthesia (cornual nerve block) reduces acute pain during the procedure but post-procedural pain (lasting 4-24 hours) requires NSAIDs such as meloxicam for effective management.
UK and EU regulations now require licensed veterinary involvement for dehorning older cattle — but calves under 2 months can still be disbudded by trained farmers with anaesthesia under vet prescription.
Polled (naturally hornless) genetics offer the permanent solution — genomically selected polled bulls now provide equivalent production performance to horned genetics in beef and dairy breeds.
The Polled movement: UK, EU, and New Zealand dairy industries have set targets of 50%+ polled herds by 2030 — reducing the need for painful disbudding across millions of animals.
Without any pain relief, disbudding causes cortisol levels 10x baseline for 4+ hours — evidence that is driving regulatory tightening across the EU and UK.

Welfare Considerations

Cattle dehorning causes substantial, preventable pain. The long-term solution is polled genetics — selecting hornless cattle eliminates the need for the procedure entirely. In the interim, all disbudding must use both local anaesthesia and post-procedural NSAIDs. Farmers, vets, and breed societies all have roles to play in accelerating the shift to polled animals.

What You Can Do

Advocate for mandatory pain relief (local anaesthesia + NSAIDs) for all cattle disbudding
Support polled genetics programs in dairy and beef breeds to eliminate the need for dehorning
Choose certified higher-welfare dairy and beef products that require pain relief for disbudding
Donate to Farm Animal Welfare Council research on accelerating polled genetics adoption
