The physical environment of farmed animals determines their daily experience. Designing spaces that enable natural behaviour is one of the most impactful ways to improve farm animal welfare.
The physical design of livestock housing determines whether animals can perform their behavioural repertoire or are constrained to a minimal existence of eating, drinking, and lying. Natural behaviour in cattle includes walking, exploring, and social interaction at distance — these require space. In pigs, rooting and manipulation require substrate. In hens, dustbathing requires dry particulate material; nesting requires secluded nest boxes; perching requires elevated structures. Environments that provide these resources enable positive welfare states; barren environments guarantee their absence. Welfare-positive design is achievable at reasonable cost and creates conditions for animals to have something approaching good lives.
