Immunocastration using Improvac is a welfare-superior alternative to surgical castration that prevents boar taint in entire male pigs.
Surgical castration without pain relief is among the most widespread and severe welfare harms in pig production globally. Immunocastration eliminates this suffering while managing boar taint. Welfare standards should require either pain-relieved surgical castration, immunocastration, or entire male production. No case exists for routine unanaesthetised surgical castration.
