Owner Compliance to an Environmental Management Protocol for Severe Equine Asthma Syndrome

Severe equine asthma (SEA) syndrome is a chronic recurrent respiratory disease, common among adult horses. The disease occurs in genetically susceptible individuals after their exposure to organic dust. Thus, environmental management has proved essential in controlling airway challenge and disease exacerbation. This is a demanding process that can only be achieved through the horse owners’ cooperation. One year after initial diagnosis of SEA in a group of 39 horses, owner compliance to an environmental management protocol was evaluated. The overall compliance to the protocol was poor and the horses’ clinical health and need for pharmacological management was related to the successful implementation of the environmental recommendations provided on disease diagnosis. •Dry hay feeding is an important trigger factor and is associated with increased cough frequency.•Owner compliance to environmental management can be challenging but is essential for severe equine asthma syndrome remission.•Lack of compliance to environmental management is associated with disease exacerbation and the need for pharmacological treatment.
