Pig Nursery Welfare: Critical Care in the Early Growth Phase

The nursery phase after weaning is a high-stress period for piglets that profoundly affects their welfare and long-term health. Management during this phase has been identified as a key welfare priority.

Key Facts

Commercial pigs are typically weaned at 21 days — far earlier than natural weaning at 13-17 weeks
Early weaning causes immune stress, gut microbiome disruption, and psychological distress
Post-weaning diarrhea causes significant mortality and suffering in nursery pigs
Enrichment materials reduce tail-biting risk by 30-40% in nursery pigs
Belly nosing and rooting are stereotypic behaviors indicating welfare deficits

Welfare Considerations

Weaning is among the most stressful events in a pig's life. Piglets are separated from their mother, moved to an unfamiliar environment with new pen-mates, and must transition from milk to solid food — all simultaneously. The immune, digestive, and psychological stress this causes is well-documented. Welfare improvements include later weaning age, providing enrichment materials like straw or chains, ensuring consistent pen temperature, and feeding wet mash rather than dry pellets to ease the dietary transition.
