Risk factors for equine fractures in Thoroughbred flat racing in North America

Ontario Racehorse Death Registry, 2003–2015: Descriptive analysis and rates of mortality

“…This policy has now been reversed, with the introduction of additional, routine tests designed to optimise the amount of information extracted from every fatality and progressively reduce the number of casualties. Most previous investigations address primarily loss resulting from musculoskeletal damage or 'breakdown' [4,6,7,9,10,13,22,26,27,29,30,[44][45][46]. For this particular source of wastage, present results are comparable.…”

“…The previously observed relationship between sex and mortality rate [4,7,9,10], and predisposition of stallions to injury may be one reason why relatively few intact stallions race. In this study, stallions represented the smallest sex group for all three breeds.…”

“…Thoroughbred individual annual exercise risk was higher than for Sbs despite the overall greater 3 Rate/1000 breed race starts for the entire study period. 4 Rate totals/1000 breed race starts for the entire study period. early performance with a view to breeding opportunities and return on investment, emphasis on precocity is greatest for the Tb.…”

Epidemiology of race‐day distal limb fracture in flat racing Thoroughbreds in Great Britain (2000–2013)

“…Uncastrated male horses were at higher odds of distal limb fracture compared to geldings and females in the all starts model. Similarly, previous studies have identified male horses to be more likely to sustain a fracture , SDFT , die or be subjected to euthanasia than their female counterparts. Perkins et al .…”

“…These results are also similar to those from other studies completed in other populations although variation in modelling strategies make comparison across studies difficult. Age has been modelled as age at first start and/or current age or as career length . Wood et al .…”
