Pig Castration: Welfare and Alternatives

Surgical castration of piglets is practiced to prevent boar taint in pork but causes pain that alternatives including immunocastration can avoid.

Key Facts

Surgical castration without analgesia is practiced on 70-80% of male piglets in the EU
Boar taint affects 3-5% of intact males and is detectable by sensitive consumers
Immunocastration using Improvac requires two injections but eliminates surgery
The EU intended to phase out surgical castration without anaesthesia by 2018 but this was not achieved

Welfare Considerations

Surgical castration without analgesia causes acute pain during the procedure and post-operative pain lasting days. Piglets that do not receive pain relief show behavioral changes including huddling, reduced activity, and vocalizations consistent with pain experience. Immunocastration provides equivalent boar taint control without surgical welfare costs but requires management changes.

What You Can Do

Support pork producers using immunocastration or raising intact males with slaughter at lighter weights
Advocate for mandatory analgesia for all surgical castrations that continue to be performed
Ask pork brands about their castration policy and transition timelines
Choose pork from countries that have moved away from surgical castration without pain relief
