Pig Weaning Age and Welfare: The Case for Later Weaning

Pigs are weaned much earlier in commercial production than in natural conditions. The welfare implications of early weaning are significant for both sow and piglets.

Key Facts

Wild pigs wean piglets naturally at 12-17 weeks of age
Commercial weaning occurs at 3-4 weeks in most EU systems
EU Directive 2008/120 sets a minimum weaning age of 28 days with exceptions
Earlier weaning causes post-weaning diarrhoea, stomach ulcers, and stress in piglets
Sows return to oestrus faster after early weaning, increasing reproductive throughput
Later weaning at 5-6 weeks reduces piglet stress behaviours significantly

Welfare Considerations

Premature weaning causes multiple simultaneous welfare challenges for piglets. Separation from the sow, change of diet, and mixing with unfamiliar pigs within days create acute distress. Post-weaning stress syndrome involves gut inflammatory responses, diarrhoea, and sometimes gastric ulceration. Later weaning, while reducing reproductive efficiency, produces more developmentally robust piglets with better immune status and lower antibiotic requirements.

What You Can Do

Support pig producers moving toward later weaning ages
Advocate for minimum weaning age requirements to be raised in EU and UK legislation
Choose pork certified to standards requiring meaningful weaning protocols
