Ventilation assessment starter kit

Ventilation and appropriate air speeds are essential for cow health and productivity. Ventilation ensures the removal of dust, heat, moisture and noxious gases from the barn, while fast moving air helps mitigate heat stress in the summer. This paper outlines the recommended ventilation rates for nursing calves to milking cows, as well as discusses the ventilation de­sign requirements, the tools and equipment needed for a venti­lation assessment, and the methods for calculating ventilation rates and air speeds.
