Dehorning and disbudding of cattle to prevent injury to other animals and handlers causes significant pain that can be substantially reduced through appropriate analgesia.
Cattle dehorning welfare is one of the clearest cases where welfare improvement is achievable, affordable, and evidence-based, yet adoption remains incomplete. Dehorning without anesthesia causes severe acute pain - studies using pain facial action units confirm this unambiguously. The combination of local anesthetic and systemic analgesia reduces welfare harm significantly and costs only a few dollars per animal. The alternative of breeding polled (hornless) cattle eliminates the need entirely. Regulatory mandates in New Zealand have shown that requirements for pain relief are achievable without industry disruption. The welfare gap between what is possible and what is practiced remains large in many jurisdictions.
