The horse’s digestive system has a great influence on the diet of the horse, their digestive system will affect the choice of food, time to eat, what to eat, their eating habits, and other related issues.

Tooth system

A horse’s teeth are fully developed, usually around the age of five, it has between 36 and 44 teeth in adulthood. Consists of 12 incisors in front of the mouth, suitable for biting or plucking to eat. There are 24 teeth used to chew, 12 premolars and 12 molars at the back of the mouth, commonly called canines or molars. The formula for their teeth is: 3.1.3-4.3 and During a grazing life, their teeth wear down, wear out of the teeth, change tooth shape, it is possible that the rate of wear and tear of the teeth is also influenced by diet and care.

From 13 to 32% of the horse, both the male and the female have “wolf teeth” teeth, which are not related to canines. Some horses, both male and female, will also develop 1-4 very small teeth in front of the molars, called wolf teeth, which are usually removed because of the need to place the brace. ) into that place. It is a gap between the incisors and molars where the mount is located directly on the gums, used to tie the reins to control the horse. Their teeth formula is nearly perfect, with incisors for cutting to gnaw food, and molars for crushing food that grow behind the crevices.


Horses are herbivores that feed mainly on coarse fibrous foods such as grass. When necessary, they also eat other plant foods, such as leaves, fruit, and bark, but are usually herbivores, not cuttings or leaves. Horses are non-ruminant animals, so they have only one stomach, like humans, but human horses can digest cellulose (the main ingredient in grass). Horses have a relatively small stomach but a very long gut which facilitates a constant flow of nutrients. Horses are herbivores with a digestive system adapted to herbivorous and plant fodder, consumed at regular intervals throughout the day.

Unlike ruminants, with their complex systems of stomachs, the equine decomposes cellulose in the “cecum”, a part of the colon, which is up to 22 meters long, losing only to the intestine. cattle, but the cecum is a bottom sealed bag, about 1m long and 0.2m in diameter can hold 30 liters of water. Thanks to the bacteria in the cecum, helping to increase food memo, making the horse digest easily. Horses are not ruminant though they also eat grass like cattle, because they do not have a four-compartment stomach, and the cecum is arranged in a straight pocket in the abdominal cavity, so it is often called a horse’s intestine, only one stomach. But unlike humans, horses have the ability to digest cellulose.
