Pig Castration Alternatives and Welfare

Surgical castration of male pigs causes pain and distress, driving demand for humane alternatives.

Key Facts

Surgical castration is performed to prevent boar taint - an unpleasant odour in pork from intact males
EU Castration Agreement targeted elimination of surgical castration without anaesthesia by 2018 but progress has been slow
Immunocastration using the Improvac vaccine prevents boar taint without surgery
Some genetics and feed regimes allow earlier slaughter before boar taint develops
Pain relief during and after surgical castration is required under EU animal welfare law

Welfare Considerations

Surgical castration without pain relief causes acute pain and distress and is a significant welfare problem across global pig production. Immunocastration and breed/management solutions that avoid castration entirely are increasingly viable and should be supported over continued reliance on surgical methods.

What You Can Do

Support pork from producers using immunocastration or entire male production systems
Ask retailers about the castration methods used in the pork they sell
Advocate for mandatory pain relief in any remaining surgical castration
Support Compassion in World Farming campaigns on pig castration welfare
