“…SD refers to the acute collapse or fatality of an apparently healthy horse possessing no clinical signs of injury or poor health, occurring during or soon after a race (Boden et al, 2005; Lucke, 1987; Physick‐Sheard & Slack, 2020). While musculoskeletal injuries reportedly account for 63%–74% of all SDs (Bimson et al, 2022; Boden et al, 2005, 2006; Clegg, 2011; Hitchens et al, 2019), cardiorespiratory disorders have also been reported to account for 56%–81% of SDs on race days (Boden et al, 2005; Lyle et al, 2011; Navas de Solis et al, 2018). Given the practical and social implications on racehorse and jockey safety, the racing industry continues to make efforts to minimise and prevent the occurrence of SDs.…”
