Investigation Into Predictors of Stallion Fertility and Associations With Oxidative Damage

Thoroughbred stallions are selected for breeding based on pedigree and racing success, often with fertility unknown. The outcome of a given breeding cannot be ascertained until 12-14 days post ovulation, meaning a lag in detection of stallion subfertility. Dismount samples are frequently analysed, post-coitus, for sperm concentration and motility, however, such analysis is highly affected by handling techniques. The purpose of this study was to investigate possible biomarkers of fertility in dismount samples, as well as management factors predictive of stallion fertility, allowing for future increased reproductive success.
