Dehorning of cattle causes significant acute and chronic pain yet is widely practised for safety reasons. Evidence-based approaches including pain management and polled genetics offer better welfare outcomes.
Dehorning is a routine welfare compromise: performed to prevent injury, it causes significant pain in the process. The welfare calculus depends heavily on how the procedure is managed. Dehorning without pain relief causes severe and prolonged suffering; appropriate sedation, local anaesthesia, and analgesia dramatically reduce but do not eliminate pain. The best welfare outcome requires shifting away from the need to dehorn at all, through breeding polled animals. Polled genetics are available for dairy and beef breeds and can be incorporated into breeding programmes without significant production compromise. The transition to polled herds is gradual but represents a genuine long-term welfare improvement. In the interim, requiring mandatory pain management for all dehorning procedures is a minimum welfare standard that should be universally applied.
