Pig Immunocastration: Welfare Alternative to Surgical Castration

Immunocastration offers a welfare-improved alternative to surgical castration for controlling boar taint in male pigs intended for pork production.

Key Facts

Surgical castration without anaesthesia is prohibited in the EU from 2022, requiring alternatives
Immunocastration uses two injections to suppress testicular function temporarily without surgery
Immunocastrated pigs retain production advantages of intact males until the final weeks before slaughter
Consumer acceptance of immunocastration has been a barrier to adoption in some markets

Welfare Considerations

Immunocastration avoids the welfare cost of surgical castration while controlling boar taint. Its adoption is a welfare advance, though the two-injection protocol requires skilled handling. The welfare of intact males - typically better than castrates in growth and feed efficiency - is preserved until close to slaughter.
