What does the Commission veterinarian maintain a list of?

The Commission veterinarian is responsible for maintaining a list of horses that are deemed unfit to compete. This is a critical aspect of ensuring the safety and well-being of the horses during races, as well as maintaining the integrity of the racing event. Horses may be considered unfit due to various health issues, injuries, or the effects of medications that could hinder their ability to race safely. By keeping this list, the veterinarian informs trainers, owners, and racing officials about which horses should not participate, thus protecting both the animals and the overall competition.

In contrast, while the other options might relate to the management of horse racing, they do not fall under the specific responsibilities of the Commission veterinarian in this context. The veterinarian’s focus is primarily on the health status of the horses rather than race participation, medication logs, or past performance records. Therefore, the emphasis on maintaining a list of unfit horses is crucial for ensuring the safety and integrity of the races.
