Pig Pain Management: Advancing Analgesia in Commercial Pork Production

Pain management in commercial pigs lags behind companion animal veterinary practice. Evidence-based analgesia protocols for routine and emergency pain are transforming welfare outcomes.

Key Facts

Common painful conditions in pigs include lameness, tail biting wounds, castration, farrowing complications, and injury from fighting
NSAIDs (meloxicam, flunixin) are effective for pig pain management but require prescription and veterinary oversight in most countries
Surgical castration of piglets without analgesia remains common in many countries despite EU requirements for anesthesia from 2022
Lame sows are significantly under-identified and undertreated — locomotion scoring identifies only the most severely affected individuals
Pain in pigs manifests behaviorally (reduced activity, changed posture, altered feeding) rather than through vocalization alone
Validated pig pain assessment tools including facial action coding systems are enabling more objective pain identification

Welfare Considerations

Pain management in commercial pigs requires overcoming multiple barriers: the stoic nature of pigs that masks pain expression, the cost and logistical challenges of veterinary analgesia at scale, the knowledge gap about pain assessment, and the economic pressures of low-margin production. Progress is being made on multiple fronts: validated pain assessment tools enable systematic identification of painful individuals; regulatory requirements for anesthesia during castration are expanding; herd health programs incorporate pain monitoring; and NSAIDs are becoming more widely used for routine procedures. The welfare impact of better pain management is substantial — lame sows, injured tail-bitten pigs, and post-surgical animals all benefit significantly from appropriate analgesia. The economic case for pain management includes reduced productivity losses from untreated pain and improved food conversion in comfortable animals.

What You Can Do

Support pork producers and certification schemes that require analgesia for all painful procedures including castration
Advocate for mandatory analgesia requirements for pig castration in all countries
Support immunocastration (Improvac) as a welfare-positive alternative to surgical castration
Encourage veterinary engagement in herd pain assessment and analgesia protocol development
Choose pork from certified welfare schemes that include explicit pain management requirements
