Pig Pain Recognition and Management on Farms

Recognizing and responding to pain in pigs is a fundamental welfare obligation, yet pain remains systematically underrecognized and undertreated in commercial pig production.

Key Facts

Pigs have similar pain sensitivity to humans and experience both acute and chronic pain
Common painful procedures in pig farming include castration, tail docking, and teeth clipping, often without analgesia
The Pig Grimace Scale (PGS) enables reliable assessment of pain using facial expression analysis
Pain reduces feed intake, growth rate, and reproductive performance, creating economic incentives for treatment
Lameness affects 10-30% of pigs in many production systems and is frequently undertreated
EU regulations require pain relief for surgical procedures but enforcement and uptake vary significantly

Welfare Considerations

Pain is one of the most significant welfare issues in pig farming globally. The historical assumption that pigs feel pain less acutely than other animals has been thoroughly disproven by neuroscience, yet pain management remains inconsistent. A lame pig in a commercial barn may experience weeks or months of chronic pain before receiving treatment or being culled. Systematic pain recognition protocols and analgesic use are not merely ethical obligations but are also economically rational.

What You Can Do

Support certification schemes (RSPCA Assured, Certified Humane) that require pain management protocols
Choose pork from producers with documented analgesic use for routine procedures
Advocate for legislative requirements that make pain relief mandatory for all piglet procedures
Support research into alternatives to painful procedures like immunological castration
Ask retailers and food companies about their pig welfare standards regarding pain management
Reduce pork consumption overall to lower demand for high-volume, low-welfare production systems
