Herbivorous Digestive System of Horses: How Does It Work?

When it comes to the animal kingdom, horses are known for their herbivorous diet. Unlike carnivores or omnivores, horses have a unique digestive system that allows them to efficiently process and extract nutrients from plant matter. In this section, we will explore the intricacies of the herbivorous digestive system of horses and understand how it works.

The Mouth and Teeth

The digestive process begins in the mouth of a horse. Equipped with strong and sturdy teeth, horses are capable of grinding down the tough and fibrous plant material. Their front teeth, known as incisors, are used for biting off grass and other vegetation, while their back teeth, known as molars, are responsible for grinding the food into smaller particles. The saliva produced in the mouth helps to moisten the food, making it easier to swallow.

The Stomach

Once the food is chewed and swallowed, it travels down the esophagus and enters the horse’s stomach. However, unlike humans and other monogastric animals, the horse’s stomach is relatively small in relation to its body size, accounting for only about 10% of the total digestive capacity. This means that the stomach has a limited role in the digestion of plant material.

The Small Intestine

The majority of the digestion in horses occurs in the small intestine, which is approximately 70 feet long and has three main sections: the duodenum, jejunum, and ileum. Here, the food mixes with digestive enzymes and bile produced by the liver and pancreas, which break down carbohydrates, proteins, and fats into smaller molecules that can be absorbed by the body.

The Cecum and Large Intestine

After passing through the small intestine, the remaining undigested food enters the cecum, a large fermentation chamber located at the junction of the small intestine and large intestine. The cecum is responsible for the breakdown of fibrous plant material through the fermentation process, aided by bacteria and other microorganisms. This allows horses to extract nutrients from the cellulose present in plants, a task that is impossible for humans.

From the cecum, the digesta moves into the large intestine, which consists of the colon and rectum. The large intestine’s main function is to absorb water and electrolytes from the digesta, further concentrating the waste material. The fermentation process continues in the colon, where bacteria continue to break down remaining fiber.

The Expulsion of Waste

Finally, the waste material, now mostly composed of indigestible fiber and bacteria, is formed into fecal pellets in the rectum. These pellets are then excreted through the anus, completing the digestive process.

In Summary

The herbivorous digestive system of horses is a highly specialized and efficient mechanism for extracting nutrients from plant matter. From the mouth to the large intestine, each part of the digestive system plays a crucial role in breaking down and absorbing the necessary nutrients. Understanding how the digestive system works in horses helps us better care for these magnificent creatures and ensure they receive the proper nutrition they need to thrive.


Is a horse a herbivore?

Yes, horses are herbivores. They primarily eat grass, hay, and other plant-based foods. Their digestive system is designed to process and extract nutrients from plant material.


In conclusion, the horse is indeed a herbivore, meaning it primarily consumes plant-based food. Their digestive system is specifically designed for processing and deriving nutrients from grass, hay, and other vegetation.
