The phase-out of gestation stalls for pregnant sows has been achieved in some countries but remains challenging globally, with implementation requiring alternative systems and producer support.
Gestation stalls prevent sows from performing basic natural behaviours including turning around, rooting and social interaction. The chronic frustration caused by this extreme confinement causes stereotypic behaviours like bar-biting in a large proportion of confined sows. Group housing with appropriate space, enrichment and feed management allows sows to express normal social and exploratory behaviours, representing a substantial welfare improvement. The management challenges of group housing are real but solvable with appropriate training and technology.
