What type of feed is typically most beneficial for a horse's energy levels during work?

High-starch grains are typically the most beneficial for a horse's energy levels during work because they provide a concentrated source of carbohydrates. Carbohydrates are a primary fuel source for horses, particularly when they require bursts of energy for activities such as jumping, racing, or heavy training sessions. Grains like oats, corn, and barley are examples of high-starch feeds that can enhance a horse's stamina and performance during demanding tasks.

While high-fiber hay and fresh grass contribute to a horse's overall diet and digestive health, they are not as energy-dense as high-starch grains. Hay and grass contain mostly structural carbohydrates, which are important for digestive function but do not provide the quick energy needed for intensive work. Fruits and vegetables, although nutritious, typically do not offer the high energy levels required during physical exertion and should be considered more of a supplement rather than a primary energy source.
