What does the small intestines do in a horse?

The small intestine in a horse plays a crucial role in digestion and nutrient absorption. It is where the majority of digestion occurs, breaking down feed components like carbohydrates, proteins, and fats. The small intestine also absorbs essential nutrients, such as amino acids, fatty acids, and vitamins, which are vital for the horse's overall health and energy. Typically, the small intestine is about 70 feet long, allowing for ample surface area for nutrient absorption.
