Routine farm procedures on pigs including castration and teeth clipping are performed without pain relief on most farms. Understanding the welfare case for analgesia drives important policy debates.
The routine performance of painful procedures on millions of piglets without analgesia represents one of the most significant preventable welfare failures in modern animal agriculture. Castration causes acute and chronic pain - even proponents of the practice acknowledge the pain, which is why they argue for analgesia. The cost of providing local anesthetic or effective pain medication at the time of castration is modest relative to the total cost of pig production. The industry's resistance reflects not genuine cost impossibility but prioritization of operational speed over animal welfare. The alternatives - immunocastration, use of entire males, or at minimum pain relief before surgical castration - are all viable and could be implemented with modest changes to production systems.
