Pig Weaner Management and Stress

Weaning is one of the most stressful events in a pig's life, causing simultaneous social, nutritional, and environmental disruption requiring careful management.

Key Facts

Weaning at 3-4 weeks requires rapid adjustment from milk to solid food
Post-weaning diarrhoea caused by enteric pathogens affects many weaned piglets
Mixing of unfamiliar piglets at weaning creates social conflict compounding other stressors
E.coli diarrhoea in newly weaned pigs responds to zinc oxide but antibiotic-free alternatives are needed
Later weaning at 5-6 weeks significantly reduces post-weaning stress responses

Welfare Considerations

Weaning imposes multiple simultaneous welfare challenges on piglets who must adjust to new food, new social groups, and new environments simultaneously. Later weaning, familiar groupings, and gradual dietary transition reduce the severity of weaning stress and associated welfare costs.

What You Can Do

Support welfare standards that require minimum weaning age above current legal minimum
Advocate for alternative post-weaning diarrhoea management that reduces antibiotic dependence
Choose pork from farms using later weaning and managed transition protocols
