Pig Weaning Stress: Management for Welfare 2026

Weaning is one of the most stressful events in a commercial pig's life and management practices that reduce weaning stress directly improve welfare outcomes.

Key Facts

Commercial pigs are typically weaned at 21-28 days in the EU, much earlier than natural weaning at 12-17 weeks
Weaning involves simultaneous separation from the sow, dietary change and social regrouping
Post-weaning diarrhoea from E. coli is the most common disease consequence of early weaning stress
Pigs weaned earlier show more stress behaviour than those weaned later

Welfare Considerations

Weaning causes acute stress from maternal separation, mixing with unfamiliar pigs, environmental change and dietary transition. Welfare priorities include providing familiar pen mates at weaning where possible, maintaining a warm and draught-free nursery environment, offering transitional diets that are palatable and digestible, providing enrichment materials to reduce redirected behaviour, and monitoring closely for post-weaning diarrhoea.

What You Can Do

Support pork producers committed to later weaning ages and improved weaning management
Advocate for research into practical methods to reduce weaning stress in commercial pig production
Choose higher-welfare certified pork from producers with better weaning standards
Support development of evidence-based minimum weaning age standards in EU pig welfare legislation
