Pig Pain Management: Science and Practice

Pigs undergo numerous painful procedures on commercial farms — from castration and tail docking to surgical correction of injuries. Pain management practices lag far behind the science of pig pain and analgesia.

Key Facts

Castration of male piglets without analgesia is standard practice in most countries and is acutely painful — piglets show pain behaviors for hours afterward
The EU has set an aspirational target to end surgical castration, with immunological castration (Improvac vaccine) as the preferred alternative
Tail docking, performed to prevent tail-biting, is painful and addresses a symptom of poor welfare rather than its cause
Research shows pigs require both local anesthetic and systemic analgesics for adequate pain control during castration
Lameness, a significant pain source, affects approximately 15% of sows at any time but is routinely underdiagnosed and undertreated
Pain scoring systems validated for pigs are now available but are not widely used in commercial production

Welfare Considerations

Pain management in pig farming exists on a spectrum from near-total absence in conventional systems to genuine multimodal analgesia in leading welfare-certified operations. The gap between best practice and common practice represents enormous quantities of preventable suffering. Scientific evidence for the pain experience of pigs is clear and well-established; the gap is in implementation. Barriers include cost, skill requirements, time pressures on stockpeople, and a culture that has historically treated pig pain as less important than pig productivity. Regulatory requirements for pain relief during routine procedures, combined with farmer education and economic support, represent the most effective pathway to closing this gap.

What You Can Do

Support pork producers and certification schemes that require pain relief for all routine procedures including castration and tail docking
Advocate for your national agriculture ministry to mandate analgesia for painful piglet procedures
Support research and implementation of immunological castration alternatives that eliminate the welfare harm of surgical castration
Choose pork certified by high-welfare schemes like RSPCA Assured or Global Animal Partnership that include pain management requirements
