Farmed Pig Castration Without Analgesia

Surgical castration of piglets without pain relief remains common in many countries despite available alternatives, causing preventable welfare harm at massive scale.

Key Facts

Approximately 100 million male piglets are surgically castrated in the EU annually
Castration is performed to prevent boar taint, an unpleasant flavor compound in meat of intact males
Most surgical castration in piglets is performed without local anesthesia or systemic analgesia
Pain during and after surgical castration is well-documented through behavioral and cortisol indicators
The EU has protocols for castration with pain relief including local anesthetic and NSAID
Immunocastration (Improvac) provides an effective alternative without surgery
Late-stage castration at market weight in intact males is used in some production systems
Norway has achieved production of intact male pigs without boar taint through management

Welfare Considerations

Surgical castration of piglets without analgesia causes documented acute pain through both the procedure itself and post-operative inflammation. The behavioral indicators of pain during castration - vocalization, struggling, and subsequent pain-related postures - are clear evidence of suffering. The scale of this welfare problem is enormous: hundreds of millions of piglets annually experiencing preventable pain from a procedure performed without pain relief. Effective analgesia protocols combining local anesthesia with systemic NSAIDs reduce pain significantly. Immunocastration alternatives eliminate surgical pain entirely. Production of intact boars without boar taint, while requiring management changes, is achievable in some systems. The welfare case for eliminating surgical castration without analgesia is supported by scientific consensus, with voluntary industry agreements in several countries.

What You Can Do

Choose pork certified under schemes requiring analgesia for piglet castration
Support legislation mandating pain relief for all surgical procedures in piglets
Reduce pork consumption to decrease demand from systems using castration without pain relief
Learn about immunocastration as a humane alternative to surgical castration
Advocate for retailer commitments to higher castration welfare standards in supply chains
Support research into production of intact males without boar taint as an alternative
