Farm Pig: Mucking Out and Hygiene Welfare

Hygiene management through regular mucking out is fundamental to pig welfare, preventing disease, reducing ammonia, and providing clean lying areas.

Key Facts

Pigs are naturally clean animals that will designate specific dunging areas away from lying and feeding areas
Well-designed pens with separate lying and dunging areas are easier to keep clean
Accumulation of slurry in lying areas increases disease risk and ammonia exposure
Solid floor pens require more frequent mucking out than slatted systems
Cleanliness of lying areas is assessed in welfare audits using body soiling scores

Welfare Considerations

Hygiene is a basic welfare requirement for pigs - forcing them to lie in their own excrement is contrary to their natural preferences and causes disease through faecal-oral transmission and skin irritation. Well-designed pens that accommodate the pig's natural tendency to dung away from lying areas, combined with appropriate mucking out frequency, provide the clean environment pigs prefer and need.

What You Can Do

Design pen layouts that encourage separation of lying and dunging areas
Muck out lying areas at frequencies appropriate to stocking density and pen design
Monitor body soiling scores as a welfare indicator of hygiene management
Review pen design and management if body soiling is persistently high
Include hygiene assessment in regular welfare audits
