Pig Shelter Design for Outdoor Welfare

Well-designed outdoor shelter is essential for pig welfare, providing protection from weather extremes while supporting natural behaviour and reducing stress.

Key Facts

Pigs cannot sweat and rely on shade and wallowing to regulate temperature
Outdoor shelter must protect from rain, wind, and both heat and cold
Ark-style shelters provide effective year-round protection in most climates
Bedding depth of at least 30cm is recommended for thermal comfort in winter
Proper drainage around shelters prevents muddy conditions that cause welfare problems
Shelter placement should be on well-drained ground away from prevailing winds
Group-housed pigs need sufficient shelter space to avoid dominant pig exclusion

Welfare Considerations

Outdoor pig systems offer significant welfare advantages when shelter is adequate. Without proper shelter, pigs face sunburn, hypothermia, heat stress, and exhausting fights to access inadequate space. Shelter design failures are one of the most common welfare deficiencies in outdoor pig systems. When shelter is well-designed and properly maintained, outdoor pigs can express natural behaviours including rooting, social interaction and exploration that intensive indoor systems prevent.

What You Can Do

Ensure shelter meets minimum space allowances for your pig numbers and sizes
Add fresh dry bedding regularly especially in wet or cold weather
Site shelters to avoid prevailing wind and maximise natural drainage
Provide shade structures separately from sleeping areas in summer
Check shelters are accessible to all pigs including subordinate animals
Inspect shelter integrity after storms or high winds
Learn species-specific temperature requirements for the breeds you keep
