Pig Immunocastration Welfare Benefits

Immunocastration offers an alternative to surgical castration or producing entire males, with significant welfare and product quality implications.

Key Facts

Surgical castration without analgesia is banned in several EU countries but still widespread
Immunocastration uses a vaccine to suppress gonadal function before slaughter
Vaccinated boars show reduced aggressive and sexual behaviors similar to surgically castrated pigs
Immunocastrated pigs show better welfare indicators during the growing period compared to surgical castrates
Consumer acceptance is the primary barrier to wider immunocastration adoption

Welfare Considerations

Surgical castration without analgesia causes acute pain and prolonged wound discomfort. Immunocastration avoids this suffering while reducing boar taint issues and maintaining welfare during growth.

What You Can Do

Support pork from farms using immunocastration or producing entire males with management
Advocate for mandatory analgesia requirements wherever surgical castration continues
Choose pork certified by schemes that eliminate or minimize castration-related suffering
