What does the racing secretary maintain a list of regarding female horses?

The racing secretary maintains a list of stallions that have covered the fillies or mares because this information is essential for breeding records, which help ensure the proper management and tracking of horse lineage. Understanding which stallions have serviced specific mares is crucial in the racing industry for various reasons, including maintaining bloodline integrity, assessing breeding effectiveness, and planning future breeding strategies. This data becomes valuable not just for the breeders but also for trainers and owners who need to understand the genetic potential of the horses they are working with.

While the breeding schedules of horses, birth records, and race performance results are critical aspects of horse racing management, they are typically kept in separate registries or files and not specifically maintained by the racing secretary in the context of this question. The emphasis on stallion coverage highlights the direct relationship between breeding activities and the respective registrations within the racing community.
