Farmed Pig Nursery Phase Welfare

The nursery phase after weaning is one of the most stressful periods in a pig's life, with early weaning practices creating welfare challenges that affect both immediate and long-term health.

Key Facts

Commercial pigs are weaned at 3-4 weeks of age, far earlier than the natural 13-17 weeks
Early weaning causes intense distress - piglets vocalize and search for their mothers for hours
Post-weaning diarrhea from gut microbiome disruption kills many early-weaned piglets
Prophylactic antibiotic use in nurseries contributes to antimicrobial resistance
Enrichment materials like straw dramatically reduce post-weaning stress behaviors
Delayed weaning at 5-6 weeks significantly improves welfare outcomes
Tail docking and castration in the nursery phase cause acute pain and require analgesia
EU regulations require pain relief for tail docking but enforcement is inconsistent

Welfare Considerations

Early weaning in commercial pig production creates an acute welfare crisis at the start of every pig's life. Piglets are neurologically and immunologically unprepared for abrupt maternal separation at 3 weeks. The distress vocalizations and search behaviors documented in early-weaned piglets are distressing indicators of suffering. The gut disruption from early weaning predisposes to disease requiring antibiotic treatment, creating a welfare and public health double burden. Extending weaning age is one of the most evidence-backed welfare improvements available to the pork industry.
