Pig Pain Assessment and Management in Veterinary Practice

Pain assessment in pigs has advanced significantly with validated tools enabling more appropriate analgesic use in commercial and veterinary settings.

Key Facts

Pigs undergo painful procedures including castration, tail docking, and tooth clipping routinely without analgesia in many production systems
The Piglet Grimace Scale and Composite Pain Scale for Pigs are validated tools for pain assessment
Meloxicam is the most commonly used analgesic for pigs but is frequently underused due to cost and prescription requirements
Research shows piglets given analgesics during and after castration show normal behavior sooner and gain weight faster
EU regulations require pain relief for castration after 7 days of age but not before - creating a welfare gap in younger animals

Welfare Considerations

Pain in pigs is real, measurable, and routinely undertreated in commercial production. Regulatory requirements for analgesia during painful procedures are inconsistent and often poorly enforced. Veterinary practitioners working with pigs face barriers including cost resistance from producers, limited approved products, and cultural normalization of pain in pig production. Evidence that analgesic use improves production parameters alongside welfare outcomes provides an economic argument that should overcome resistance. All painful procedures should be accompanied by appropriate pre- and post-procedure analgesia.

What You Can Do

Support campaigns for mandatory analgesia with all painful procedures in pig production
Choose pork certified to standards requiring pain relief for castration and other procedures
Advocate for elimination of surgical castration through immunocastration or entire male production
Support veterinary professional education on pain recognition and analgesic protocols in pigs
Ask farmers and retailers about analgesia protocols for routine procedures in their pork supply chains
