Alternative farrowing systems that allow sow movement while protecting piglets are being developed and trialed, representing an important welfare advance.
Alternative farrowing system development represents one of the most significant ongoing welfare advances in pig farming. The challenge is real: sows are heavy animals that can accidentally crush piglets when rolling or lying down, and this crushing mortality is significantly reduced by farrowing crates. However, the welfare cost to sows confined in crates is also real and significant. The resolution requires systems that protect piglets through design rather than sow confinement - appropriately dimensioned pen areas with heated piglet protection zones where piglets can retreat, flooring that provides grip for sows rising and lying, and bedding that allows nest-building behavior. Sweden's decades of experience with loose farrowing demonstrates that successful management is achievable. The farmer training required to manage loose farrowing systems effectively is an investment that pays welfare dividends for both sows and piglets.
