Pig Weaning Stress Management Strategies

Weaning piglets from the sow is a major welfare event requiring careful management of nutritional, social and environmental transitions simultaneously.

Key Facts

Piglets are typically weaned at 21-28 days in commercial systems
Natural weaning would occur at 13-17 weeks
Early weaning causes gut changes increasing disease susceptibility
Post-weaning diarrhoea is a major health and welfare problem
Mixing unfamiliar piglets at weaning causes aggression and fighting
Providing familiar bedding and gradual diet transition reduces weaning stress

Welfare Considerations

Weaning represents a triple stressor for piglets - simultaneous removal from the sow, nutritional transition from milk to solid feed, and social mixing with unfamiliar animals. Commercial weaning at 3-4 weeks is significantly earlier than biological norm, creating welfare challenges requiring substantial management to mitigate. Welfare-focused producers use longer lactation periods, provision of creep feed before weaning, and keeping litters together post-weaning.

What You Can Do

Support welfare schemes that allow longer suckling periods where feasible
Choose pork products with verified welfare credentials on weaning management
Advocate for research into management strategies reducing weaning stress
Support legislative changes requiring later minimum weaning ages
