The farrowing period is one of the most welfare-critical times for sows and piglets. Alternatives to farrowing crates that protect piglets while allowing sow movement are being developed and adopted.
Farrowing crates were introduced to reduce piglet crushing losses, but impose severe welfare costs on sows: complete restriction of movement, inability to perform nesting behaviour, and social isolation. Research demonstrates that sows are highly motivated to build nests before farrowing and experience significant frustration when prevented from doing so. Free farrowing systems — using protected areas, anti-crush bars, and good nest design — have been shown to achieve comparable piglet survival with substantially better sow welfare. The transition requires investment and management skill but is technically feasible. Consumer pressure and legislative change are both driving the industry toward adoption.
