Pig Weaning Age and Welfare

Early weaning of piglets before 21 days causes welfare problems including post-weaning disease and behavioral stress.

Key Facts

EU regulations require minimum 21 day weaning age to protect piglet welfare
Some operations wean at 17-18 days causing increased disease and behavior problems
Post-weaning stress syndrome involves diarrhea, reduced intake, and immune compromise
Maternal milk provides immune factors and social comfort that abrupt weaning removes

Welfare Considerations

Piglets weaned before 21 days face abrupt removal from maternal milk and social contact at a physiologically vulnerable time. Immune function that depends on continued maternal antibody transfer is compromised. Post-weaning diarrhea causes dehydration and pain. The stress of abrupt social separation causes cortisol spikes affecting development. Later weaning at 28+ days improves piglet welfare outcomes substantially.
