Pig Pen Design for Natural Behaviour

Pen design profoundly influences the ability of pigs to express natural behaviours including rooting, social exploration, and rest, with design improvements delivering measurable welfare gains.

Key Facts

Pigs spend 50% of active time foraging and rooting in natural environments
Barren concrete pens with limited space suppress natural behaviour and increase aggression
Deep straw pens allow rooting, nest-building, and foraging behaviours
Raised platforms provide spatial complexity and reduce aggression in group-housed pigs
Outdoor systems with wallows allow thermoregulation and natural skin care behaviours

Welfare Considerations

Pen design that prevents natural behaviour causes frustration and psychological suffering. Evidence-based design improvements deliver measurable welfare gains at manageable cost.

What You Can Do

Support welfare standards requiring space, substrate, and complexity in pig housing
Advocate for straw-based systems or outdoor access in pig production standards
Raise awareness of pen design as a fundamental welfare determinant in pig farming
Support research into low-cost pen modifications delivering high welfare benefit
