The mulching of the barn is an essential mission of a dairy farmer like Alain André, the manager of La Grange de la Haute Vallée in Albepierre-Bredons. By its frequency and the quantity and nature of the straw used, it ensures the quality of the cattle's litter. Beyond the comfort and cleanliness of the animals, adequate mulching prevents mammary inflammations related to humidity, bacterial proliferation, and the persistent presence of excrements.
