“The stable environment invariably presents challenges of dust, mould and proper ventilation,” says Susan Raymond, instructor of Equine Guelph’s Management of the Equine Environment online course. “Most horses are well equipped for living outdoors and thrive, provided certain provisions are met.” Dr. Raymond completed her PhD in investigating the effects of exposure of horses to mycotoxins. She has also been involved in air quality research, which provided practical recommendations to the horse industry on stable design and management.
