Adequate bedding is fundamental to the welfare of housed livestock, enabling comfortable lying, reducing lameness, and maintaining cleanliness, yet many systems provide insufficient bedding.
Lying comfort is one of the most direct and measurable welfare outcomes for housed livestock. Cows that cannot lie comfortably stand for longer, develop hock injuries, and show hormonal stress responses that affect reproduction and health. The link between bedding quality and lying behaviour is so well established that lying time monitoring is used as a welfare indicator in farm assurance systems. For pigs, bedding serves both comfort and behavioural needs: rooting and nest-building behaviours that cannot be expressed on bare concrete floors can be expressed in straw, significantly improving both physical and psychological welfare.
