Castration of male cattle is widely practiced to control behaviour and improve meat quality, but the procedure causes significant pain and welfare harm without adequate analgesia.
Cattle castration without pain relief is a significant welfare concern. Evidence from cortisol and pain behaviour studies shows sustained pain lasting 24-48 hours after all castration methods. Pain management with local anaesthetic and NSAIDs is effective and inexpensive relative to animal value. Adoption of mandatory analgesia for castration is growing in welfare standards.
