Housing design profoundly shapes livestock welfare through its effects on space, air quality, light, noise, substrate, and social dynamics across species and production systems.
Barn design is a welfare determinant that persists for decades once built, making welfare-conscious design at the planning stage critical. Air quality management including ammonia levels, dust, and humidity directly affects respiratory health. Flooring — slatted, solid, or bedded — determines lying comfort, cleanliness, and foot health. Natural lighting including UV exposure is important for bone health and normal behavioural rhythms. Design that incorporates welfare requirements as primary specifications rather than afterthoughts consistently delivers better animal welfare outcomes at comparable cost.
