Outdoor farrowing huts provide an alternative to farrowing crates, allowing sows to express natural behaviours while raising welfare and ethical consumer concerns about neonatal piglet mortality.
The farrowing crate debate exemplifies a direct welfare conflict between sow welfare and piglet welfare. Crates virtually eliminate crushing but severely restrict one of the most important behavioural motivations — nesting — at a time of peak reproductive stress. The evidence is clear that crates cause significant welfare harm to sows: chronic frustration, lameness from restricted movement, and inability to respond to piglet distress calls. Well-managed outdoor systems with appropriate hut design and bedding can reduce crushing to close to crate levels while vastly improving sow welfare. The welfare equation favours well-managed free-farrowing systems over crates when management is of sufficient standard.
