The physical design of dairy cow housing profoundly influences welfare outcomes, with cow comfort principles providing evidence-based guidance for welfare-positive design.
Dairy cow housing design directly determines the welfare outcomes achievable in housed systems. Cubicle dimensions that are too short prevent normal lying behaviour and force cows to lie with legs protruding into the passage. Inadequate mattress depth causes pressure sores and knee abrasions. Feed barrier designs that allow head locking or cause neck injuries prevent adequate daily feeding time. Poor lighting makes stockperson detection of early illness difficult and may disrupt cattle circadian rhythms. The investment in welfare-positive housing design — wider cubicles, deeper mattresses, appropriate feed barriers, and good lighting — pays returns in reduced lameness, improved lying time, and lower disease incidence. Housing design is a welfare decision that has decades of impact.
