Pig Weaning Stress Reduction Strategies

Weaning is one of the most stressful events in a pig's life. Evidence-based strategies significantly reduce the acute and chronic stress of weaning.

Key Facts

Weaning causes separation stress, dietary change stress, and social regrouping stress simultaneously
Post-weaning depression and anorexia are common welfare concerns
Providing creep feed before weaning familiarises piglets with solid food
Weaning in familiar groups rather than remixing reduces aggression stress
Oral enrichment in the post-weaning period reduces abnormal oral behaviours

Welfare Considerations

Pigs at weaning experience multiple concurrent stressors that cause significant acute and chronic welfare compromise. Managing each stressor - gradual feed transition, familiar social groups, enrichment, and adequate space - reduces the overall welfare impact. Increasing weaning age from the legal minimum to 28 or more days significantly improves welfare outcomes.

What You Can Do

Support welfare standards requiring management of multiple weaning stressors simultaneously
Advocate for increasing minimum weaning age above 21 days
Choose pork from farms with documented post-weaning management protocols
