The horse's stomach is very small compared to the large size of this animal. It has a capacity of 7 to 15 liters and represents only about 8% of the entire digestive system. This means that it can empty in just 20 minutes and thus explains why the horse eats almost all day long if it has the opportunity.

Furthermore, unlike humans, where the stomach only produces hydrochloric acid when there is food to digest, the horse's stomach produces it continuously (whether the stomach is empty or not). It can produce up to 72 liters of acid in just 24 hours. Only the production of saliva can naturally reduce the acidity level of its stomach. And again, unlike us who have the power to salivate simply by looking at or thinking about our favorite dish, the horse's system, on the other hand, only salivates when it has food in its mouth and is chewing. Hence the importance of feeding the horse frequently since this physiological peculiarity makes it susceptible to stomach ulcers.

It is now easier to understand that in horses, small, very frequent meals are essential to respect their digestive physiology and therefore, to maintain a healthy digestive system. This is why in nature, horses eat for 16 to 20 hours a day, and sometimes even more...
