Dehorning of cattle causes significant pain and is one of the most common welfare-relevant procedures in beef and dairy farming. Alternatives and welfare standards are advancing.
Cattle dehorning is one of the most common painful procedures in livestock farming, performed on millions of animals annually with inadequate or no pain relief in many jurisdictions. The acute pain of disbudding or dehorning without anaesthesia is severe and well-documented — calves show elevated cortisol, behavioral pain indicators, and immune effects that persist for days. The welfare solution is not eliminating horn management, which reduces injuries to other animals and workers, but ensuring adequate analgesia through local anaesthetic and NSAIDs for every procedure. EU regulations now require pain relief for disbudding, and other jurisdictions are following. The development of polled genetics through traditional breeding or gene editing offers the prospect of eliminating the need for dehorning entirely — a welfare advance that removes the procedure from farming practice.
