Castration of male lambs is practiced by the majority of sheep producers to prevent unwanted breeding and improve meat quality, but causes acute and prolonged pain that is frequently managed inadequately — representing one of the most prevalent routine welfare failures in sheep farming.
Castration without adequate pain relief causes unnecessary suffering on an enormous scale — millions of lambs experience this procedure annually in the UK alone, with variable pain management. The suffering is not brief: rubber ring castration causes prolonged pain lasting days as the scrotal tissue becomes necrotic. The argument that lambs are too young to experience this pain is definitively refuted by the behavioral and physiological pain indicators observed in affected animals. The barrier to better pain management is partly cost, partly training, and partly the normalisation of the procedure as routine and therefore unproblematic. Better standards, including mandatory pain relief requirements, are both achievable and would prevent significant suffering.
