Surgical castration of male piglets to prevent boar taint causes significant pain, driving research into immunocastration and selective breeding alternatives with better welfare profiles.
Surgical castration of male piglets without anesthesia is one of the most common painful procedures in intensive pig farming. Even with pain relief, surgery causes acute pain and post-operative discomfort. Millions of piglets experience this procedure annually. Immunocastration with Improvac eliminates the need for surgery, providing equivalent product quality without surgical pain. The welfare case for transitioning to immunocastration is strong - it achieves the same commercial objective without the pain of surgery. Progress has been slow due to consumer reluctance and industry inertia, despite immunocastration's superior welfare profile.
