Weaner Pig Welfare After Separation

The period after weaning is one of the most stressful in a pig's life and carries significant welfare risks.

Key Facts

Piglets in commercial systems are weaned at 3-4 weeks compared to 12-17 weeks in natural conditions
Post-weaning diarrhoea is the most common disease of weaner pigs and causes significant mortality
Mixing litters at weaning creates fighting that compounds the stress of separation
Feed transition at weaning from milk to solid feed causes gut health challenges
Providing creep feed before weaning reduces the shock of dietary transition

Welfare Considerations

Weaning at 3-4 weeks in commercial pig production is significantly earlier than natural weaning, creating a cluster of simultaneous welfare challenges. Separation from the sow causes acute distress. Mixing with unfamiliar piglets causes fighting. The dietary transition from milk to solid feed causes gut health problems. Environmental change from farrowing accommodation to nursery housing is stressful. Each of these challenges alone is significant — their simultaneous occurrence creates a welfare risk period that requires careful management to minimise suffering.
