With proper ventilation, you are protecting the animals, the building and the quality of milk produced. Light Windows are essential in a closed barn. They permit sunlight for warmth and drying and provide a source of vitamin D for the animals. Well-lighted barns usually are kept cleaner. In summer, open windows are important for air movement.
Loose housing is an old system with many desirable features.
With plenty of bedding, the manure pack for a goat herd can be kept fairly clean and dry. Heat produced within the pack makes a warm bed. There is ample exercise area and an opportunity for the goats to move around. This type of housing, however, presents a few problems. A built-up manure pack, even though dry on the surface, releases a lot of moisture into the barn air.
