Group farrowing systems allow sows to farrow together. Research into their welfare implications is informing next-generation farrowing system design.
Group farrowing represents a frontier in sow welfare research - allowing social behavior around parturition while protecting individual piglets. Early results suggest that well-designed group systems can achieve good outcomes for both sows and piglets. This area of welfare research is moving toward commercial application and represents the next generation of farrowing system design.
