The transition from farrowing crates to free farrowing systems requires training, pen design, and management changes to protect both sow and piglet welfare.
Transitioning to free farrowing without adequate training and pen design can initially increase piglet mortality, discouraging adoption. However, with appropriate training in supervision and intervention, piglet survival in free systems can match or exceed crated systems while dramatically improving sow welfare. Support programs providing training, pen design guidance, and economic assistance are critical for transition success.
