Abstract

Abstract
Background: Up-to-date figures on early losses of Thoroughbreds from the racing industry can inform strategies to improve retention and incentivise traceability of Thoroughbreds during this early life period.
Methods: Data on Thoroughbred mares bred in 2013–2014 and training, racing and sales information of their live offspring were analysed. The proportions and 95% confidence intervals (95% CI) of the entire 2014–2015 United Kingdom and Ireland foal crops that entered training, raced, were imported and/or exported between birth and the end of their third year of life, as well as the racing performance of these horses as 2- and 3-year-olds were described.
Results: A total of 20,661 mares produced 28,282 live foals. Of them, 47.2% (95% CI: 46.7–47.8; n = 13,354) entered training by the end of their third year of life. Of these, 10,595 (79.3%; 95% CI: 78.7–80.0) raced at least once. Around 20% (n = 5712) of horses were exported by the end of their third year of life, of which 3526 (61.7%) had been in training. The overall mortality during the study period was 7.6% (n = 2123).
Conclusion: A considerable proportion of Thoroughbreds had not entered training by 3 years of age but of those that had, the proportion that raced at least once was high. Further research is needed to establish reasons for premature losses from the industry
