Free-stall dairy housing design profoundly affects cow welfare. Evidence-based design standards for stall dimensions, flooring and ventilation can dramatically reduce suffering in housed cattle.
Free-stall dairy housing design is a major determinant of cow welfare and is often poor in practice. Stalls that are too short, too narrow or lack adequate bedding force cows to adopt abnormal postures when lying, increasing hock injuries, knee abrasions and lameness. Cows that cannot lie comfortably spend less time lying, which is associated with elevated stress, reduced milk production and poorer immune function. The difference between a well-designed and poorly designed free-stall barn can mean the difference between herds with 15% lameness and herds with 35% lameness — representing hundreds of animals in unnecessary chronic pain on each farm. Investment in stall refurbishment and deep sand bedding delivers measurable welfare and financial returns.
