Like in La Grange de la Haute Vallée, hay is usually stored indoors in a dedicated place on farms, such as a hayloft. This precaution is necessary to avoid losses in dry matter and nutritional quality. The main factor in the deterioration of dry fodder is the absorption of moisture from the soil, responsible for the loss of nutrients. The process of hay bales distribution is another potential source of significant loss that the farmer can minimize. He can opt for a daily and individualized distribution of fodder that would reduce the quantity of hay rejected by the cows.
