Gestation crates for pregnant sows are among the most criticized practices in intensive animal agriculture. The global transition toward group housing systems represents significant welfare progress, though implementation challenges remain.
Gestation crate reform represents one of the most significant farm animal welfare policy advances of the past two decades. The welfare case against gestation crates is overwhelming: confining an intelligent, highly motivated animal in a space where she cannot turn around for most of her pregnancy causes frustration, muscle atrophy, bone weakness, and measurable psychological suffering. However, the transition to group housing is not without welfare challenges — sows in groups compete aggressively, and poorly managed group systems can produce welfare problems comparable to or exceeding crates. The key insight from welfare science is that group housing requires genuine management investment: appropriate group sizes, sufficient feeding stations, space that allows smaller individuals to escape dominant animals, and monitoring for injuries. When done well, group housing is substantially better; done poorly, it trades one welfare problem for another.
