Comment améliorer la qualité sanitaire des fourrages pour réduire les pathologies respiratoires équines ?

Abstract : Dust, moulds, pollen and endotoxins occurring in forage are considered to be among the main etiological agents of equine pulmonary disease. An experiment based on forage harvested from permanent grassland in Lower Normandy showed that certain cultivation practices (balinghay with 75% dry matter content) or even rain after cutting increase the amount of dust and fungal spores (mainly toxigenic fungus such as Aspergillus fumigatus) breathed in by horses. Alternatively, barn drying, haylage and propionic acid used as a preservative help control dust and mould when weather conditions prevent harvesting hay with 85% dry matter content. The analysis of single-species and commercial forage used to feed horses suggests that carefully selecting flora when sowing grassland could also help overcome this problem.
