Gastric ulcer
Problems with a horse’s stomach, especially ulcers in the stomach, are an increasingly common and growing problem. The vast majority of horses today have stomach problems and even ulcers in the stomach. A horse can develop an ulcer in a very short time!
A horse’s stomach is relatively small, about 8-15 liters. Also, the function of a horse’s stomach is very different from that of many other animals.
In predators, for example, the stomach serves as a repository for food. They eat a large meal, the prey, in 1x. In predators, therefore, the stomach is an important part of the digestive process.
In horses, the stomach is only a kind of conduit between the esophagus and the small intestine. Horses in nature eat throughout the day, so the stomach is set up for constant activity.
The wall of the stomach is lined with mucous membrane and is divided into 2 parts. The lower part is very glandular (the glandular part) and therefore has a lot of protection. However, the upper part of the stomach is very glandular (the squamous part), it has only a thin layer of cells and therefore little protection.
