Castration of male cattle is routinely performed for management and meat quality reasons. The welfare evidence is clear: castration causes significant pain, and analgesia dramatically improves welfare outcomes.
Cattle castration welfare is one of the clearest examples of known effective welfare interventions that are inconsistently applied in practice. The pain of castration — acute during the procedure and extending days to weeks afterward through inflammation and healing — is now extensively documented. Effective pain relief is available and inexpensive: local anaesthesia for the procedure and NSAIDs for post-procedural inflammation reduce both acute and chronic pain significantly. Despite this, the majority of cattle castrations worldwide are performed without any analgesia. Age at castration is an additional welfare variable: younger calves experience less severe acute pain responses. Immunological castration — a vaccine-based approach — eliminates the pain of physical castration entirely and provides equivalent management benefits, but requires two doses and has faced adoption barriers from marketing and consumer perception issues.
