Shoreview, Minn. - Many calf barns rely on natural ventilation to provide clean, fresh air to calf pens. But, as the weather cools down and winter approaches, there can be a tendency to close the doors, windows and curtains on the calf barn in an effort to reduce drafts. Preventing cold air from blowing on calves can help keep calves warm, but when buildings are closed proper air exchange to keep calves healthy through the winter months can be prohibited.
Winter calf barn ventilation
The goal for wintertime ventilation is to have a minimum of four interior air exchanges per hour in calf barns, which can be provided by a positive pressure ventilation system.
