"Breed differences in mortality provide pointers toward management strategies that could reduce mortality, enhance welfare, increase longevity, and reduce costs of participation," wrote the study authors. "Exercise-associated mortality, in particular, is clearly related to the nature and intensity of competition undertaken by the different breeds and may reflect the time different industries allow for preparation of young athletes." In the U.K., Sarah Rosanowski, PhD, PGDipl. VCS, and colleagues evaluated risk factors for race-day fatalities in flat racing (not jumping obstacles) Thorough- breds in Great Britain from 2000 to 2013 as part of her postdoctoral research at the Royal Veterinary College. 2 She's currently an assistant professor in evidence-based veterinary medicine for the Centre for Applied One Health Research and Policy Advice at the City University of Hong Kong's Jockey Club College of Veterinary Medicine and Life Sciences. The study included 806,764 race starts, 548,571 of which were on the turf. Out of 610 fatalities, 377 (61.8%) occurred on the turf. The incidence of race-day fatality during all flat racing was 0.76 per 1,000 starts, with 0.69 per 1,000 starts on turf and 0.90 per 1,000 starts on all- weather (synthetic) surfaces. This indicates that all-weather surfaces increase fatality risk, says Rosanowski, compared to turf. Her team divided fatality causes into three categories: ■ Musculoskeletal injuries (88.8%); ■ Nonmusculoskeletal injuries (10.3%); and ■ Related to both (0.9%). Of musculoskeletal-injury-related deaths, 75.5% were due to fractures, with tendon or ligament injuries, fetlock dislo- cation, and multiple injuries accounting for the rest. Of nonmusculoskeletal-injury-related deaths, 8.6% were due to vascular catas- trophe (any terminal event of vascular origin, such as cardiac issues or ruptured aortas); sudden death due to this cause is rare compared to musculoskeletal injury, says Rosanowski. They attributed a small proportion of deaths to epistaxis ( bleeding from the nostrils), lacerations, other soft tissue injuries, or multiple causes. Risk factors on both turf and all- weather tracks included a firmer (turf) or faster (all-weather) racing surface, longer race distance, wearing an eye cover such as blinkers for the first time, increased age, racing in autumn or summer, horses in their first year of racing, and high average performance scores (better- performing horses). An increased number of starts reduced a horse's odds of fatality. Auction races (restricted to 2- or 3-year- olds bought or sold at certain public auc- tions) had 1.46 times the odds of fatality as other race types. Turf horses running in Group 1 races (the highest-level stakes race) were 3.19 times more at risk.
