Farmed Pig Pain Management: Closing the Gap Between Science and Practice

Pain management for farmed pigs lags significantly behind companion animal medicine. Research is advancing but application remains inconsistent across the industry.

Key Facts

Castration, tail docking, and teeth clipping are performed on piglets in many countries without analgesia
The EU requires pain relief for surgical castration of pigs over 7 days old
Validated pig pain assessment tools including the Pig Grimace Scale allow objective pain scoring
NSAIDs like meloxicam reduce post-operative pain and improve production outcomes when used
Stockperson attitudes to pig pain significantly predict whether pain relief is actually administered

Welfare Considerations

The gap between available pain management options and their routine application in pig farming reflects a combination of economic pressure, regulatory inadequacy, and cultural attitudes that discount pig sentience. Piglets undergoing castration and tail docking without analgesia experience acute pain indistinguishable from that caused by equivalent procedures in other species. Post-procedure pain lasting hours to days without treatment is preventable. Training programs that change stockperson attitudes toward pig pain — rather than simply teaching protocols — are the most effective intervention for changing practice. Economic analysis consistently shows that pain management costs are offset by production benefits in most systems.

What You Can Do

Choose pork products from producers certified to use analgesia for all painful procedures
Support legislative campaigns for mandatory pain management in pig farming across all EU and US states
Advocate for Pig Grimace Scale training in veterinary and stockperson education programs
Reduce pork consumption overall, shifting remaining purchases to certified humane products
