What should you provide evidence of when assessing a horse's dietary habits?

Providing documentation of the types and amounts of food fed is essential when assessing a horse's dietary habits because it allows for a comprehensive understanding of the horse's nutrition and health needs. This information can help identify any potential deficiencies or excesses in their diet, which can directly impact their performance, well-being, and overall health.

Understanding the specific types of feed—whether grain, hay, supplements, or forage—and the quantities being consumed enables the assessor to make informed recommendations or adjustments to the horse's feeding regimen. By closely monitoring and documenting dietary intake, one can correlate feeding habits with the horse’s physical condition, behavior, and energy levels, which are crucial for maintaining optimal health and performance.

Other elements, such as exercise routines and veterinary visits, offer valuable insights but do not provide a direct view of the horse's nutritional intake. Equipment used may impact management but does not relate to the dietary habits being assessed. Therefore, focusing on the types and amounts of food fed is fundamental for proper dietary assessment.
