Testing the need for an educational campaign for wounds with UK equine stakeholders

logistic and linear regression modelling, including farm and stallion as random effects, were used to investigate associations between maternal, gestational, and early-life exposures and race performance outcomes.Results: Overall, 76% (98/129, 95% CI: 68-82) of horses raced, making a median of 7 starts (IQR 4-11, range 1-23) and earning a median of 6,898 (IQR: 1712-17987, range 0-197,601).Increasing average daily turnout time (hours) in the first 6 months of life and age at weaning (days) were associated with increased odds of racing (OR 1.4, 95% CI:1.1-1.8 and OR 1.03, 95% CI: 1.01-1.05,p < 0.001, respectively).Age at weaning was also positively associated with the total number of runs by the end of the 3-year-old (0.09, 95% CI: 0.04-0.13,p < 0.001).Main limitations: Absence of training-related data; low study power for some exposure variables.Conclusions: Early-life turn out time and age at weaning are associated with later-life performance outcomes.This could be due to increased opportunity for positive musculoskeletal tissue adaptation and optimal rates of growth and development during a critical window of developmental plasticity.
