La valorisation des prairies remarquables du Parc Naturel Régional de Lorraine : Un nouveau débouché économique dans la filière foin

Abstract : On the territory of the Regional Natural Park of Lorraine, meadows are called "remarkable" by their important flora and fauna biodiversity. European aid not being sufficient, the Park has proposed to set up a hay industry to hay meadows from the Park has high added value and could meet the expectations of equine industries, pet stores and zoo. A study allowed us to report on hay quality criteria. The bibliographic analysis and the field trips have assessed the potential risks of toxicity and quality criteria met. The only risk of toxicity is due to the presence of autumn crocus. Safety from this analysis is low, this first work will be supplemented by other studies. The completed quality criteria are the following: long strands, percentage grasses, broadleaf weeds and legumes, fiber loaded, reasonable protein concentration levels in suitable minerals. One of the most important criteria is a dust-free hay. The woolly velvet grass, a plant with high hairiness, produces dust by drying and is present on an average of 19% in the analyzed plots. It is, however, not possible to state that hay will be very dusty because we do not know the amount of dust produced from this plant. The various works carried out during this study allowed us to start a test marketing in 3 pet stores in Lorraine, starting in September 2015.
