Housing cattle, sheep, and other livestock through winter raises welfare questions around space, ventilation, substrate, and social management that determine whether indoor periods harm or protect animals.
Winter housing welfare quality varies from excellent to very poor depending on housing design and management. Well-designed cubicle systems with appropriate neck rail position, rubber matting, and good lying space can provide comfortable rest. Poorly designed systems cause chronic lameness from concrete surfaces and competitive access to lying space. Overstocked yards with accumulated slurry cause foot rot and mastitis. Straw yards, when well managed, support natural behavioral expression. The critical variables are stocking density, substrate quality, and management attention.
