Disbudding and dehorning are among the most painful routine procedures in cattle farming. Understanding why these procedures are performed and how welfare can be improved reveals important principles of farm animal care.
Disbudding and dehorning without anaesthetic causes measurable and significant acute pain. The hot-iron disbudding procedure burns through sensitive horn bud tissue with direct nerve involvement. Behavioural pain indicators including ear flicking, head shaking, and vocalisation are observed consistently. Post-operative sensitivity and inflammation cause ongoing discomfort for days. The availability of local anaesthetic and meloxicam pain relief makes the continuation of these procedures without pain management difficult to justify, particularly given the modest additional cost. Breeding programmes producing polled (hornless) cattle address the root cause of the problem and are progressing through both conventional breeding and gene editing approaches.
