Scientific evidence on gestation crate alternatives provides clear guidance on how to improve sow welfare while maintaining productive farming systems.
Research on gestation crate alternatives has matured to the point where the welfare case for group housing is clear, and the practical challenges of implementation are well-understood. Sows in group housing systems with appropriate space, resources, and management express normal social behaviors, move freely, and show lower levels of chronic stress than those in individual confinement. The main challenge - aggression at mixing and resource competition at feeding - is addressable through well-designed management systems. Electronic individual feeding stations allow precise ration control without requiring individual confinement. Systems with adequate space, bedding materials, and escape routes manage aggression effectively. The countries that have completed the transition to group housing have demonstrated that productive, profitable pig farming is achievable without gestation crates, removing the economic justification for continued individual confinement.
