Is limiting equine performance influenced by high levels of dust in the respiratory system of equine that dangerous for horses?
At the highest levels of performance, limiting aerobic capability can massively affect results. Every effort should be made to reduce dust exposure. Long-term investment into providing stabling design that culminates in the reduction of the aerosolization of inhalable particles and clearing of particulates should be considered and careful planning into natural ventilation and storage of forage and bedding should be taken. Only low dust content forage should be fed and when not available soaking or steaming can be useful. Deep littering bedding may be a useful strategy in reducing dust aerosolization.
Environmental monitoring using real-time monitoring is useful in identifying dust levels, however, BZ monitoring will be more accurate in calculating dust inspired by the horse. Less invasive methods of monitoring in the BZ need to be investigated.
