Tracking the worldwide movement to end gestation crate confinement for breeding sows, examining documented welfare improvements and remaining challenges.
Gestation crates represent one of the most welfare-compromising systems in modern agriculture. Sows are highly intelligent, social animals who suffer profoundly from extreme confinement that prevents almost all natural behavior. The inability to turn around, exercise, or interact normally with other pigs causes chronic frustration, stereotypic behaviors, and physical deterioration. Research consistently shows that group housing systems, when well-managed, substantially improve sow welfare outcomes across behavioral, physiological, and health metrics.
