The horse is unique in that most of the digestion of their feed occurs in the hindgut through the process of fermentation with the help of billions of naturally occurring bacteria and protozoa (together known as microbes). The cecum and large colon
Where does fermentation of fibrous feeds occur in the horse?
Equine Digestion Step 4: Fiber Fermentation & Energy Production in the Hindgut . The hindgut is composed of the cecum, colon and rectum. The cecum and colon together can hold up to 32 gallons of fibrous material that slowly ferments over 2-3 days.
Are horses cecum fermenters?
The microbial fermentation occurs in the digestive organs that follow the small intestine: the large intestine and cecum. Examples of hindgut fermenters include proboscideans and large odd-toed ungulates such as horses and rhinos, as well as small animals such as rodents, rabbits and koalas.
Where are Roughages fermented in a horses digestive tract?
Modified monogastrics go through the same process: Food starts at the mouth, then goes through the esophagus, stomach, small intestine, and large intestine to the cecum . The cecum is where fermentation occurs. Here nutrients are taken from the food and then it goes through the rectum and out of the body.
How do horses absorb water?
The large intestine is the primary site of fibre digestion and net water absorption. Significant amounts of phosphorus are also absorbed from the large intestine. Many factors such as rate of passage, processing of feeds, level of intake, work and maturity of plant may influence digestive ability.
Why horse is not ruminant?
Horses are not ruminant animals. Ruminant animals have four compartments within their stomach that digest their food in stages. Horses only have one compartment in their stomach which means they do not fall within the ruminant category.
Where is the transition from midgut to hindgut?

What does the cecum do in horses?
The equine cecum serves as a storage site for water and electrolytes . Fiber consumption can increase water consumption, and the extra water is held in the cecum until absorption. The additional water adds some weight to your horse, but it helps replace crucial electrolytes lost from heavy sweating.
What is the purpose of the cecum?
The main functions of the cecum are to absorb fluids and salts that remain after completion of intestinal digestion and absorption and to mix its contents with a lubricating substance, mucus . The internal wall of the cecum is composed of a thick mucous membrane, through which water and salts are absorbed.
What is a hind gut?
: the posterior part of the digestive tract also : intestine.
Does a horse have four stomachs?
People often wonder how many stomachs does a horse have, but the horse is a non-ruminant herbivore . Non-ruminant means that horses do not have multi-compartmented stomachs as cattle do. Instead, the horse has a simple stomach that works much like a human’s.
Why are horses called hindgut fermenters?
The horse is a hindgut fermenter, meaning that the large intestine is the site of fermentation of ingested fiber . ... Since the bacterial and protozoal flora of the hindgut are geared for fiber fermentation, the large intestine is susceptible to upset if it receives large amounts of undigested sugars.
Do horses have a monogastric digestive system?
They are grazing animals with digestive systems designed for constant consumption of plant food. Unlike most other herbivores, the digestive system of the horse is considered monogastric rather than ruminant. Digestive organs include the stomach, small intestine and large intestine.
Why can’t horses throw up?
Horses have a band of muscle around the esophagus as it enters the stomach. ... Horses almost physically can’t because of the power of the cut-off valve muscle . Normally, USA Today concludes, if a horse does vomit, it is because its stomach has completely ruptured, which in turn means that the poor horse will soon be dead.
How many stomachs does a horse have?
Horses have a non-ruminant monogastric digestive system. Thus, horses only have one stomach . Horses can quickly graze large areas but are not as efficient at extracting energy from the food as ruminants that chew the cud. Cows and other ruminants have complex multichambered stomachs.
What is a horse digestive system called?
The equine gastrointestinal tract can be divided into two main sections: the foregut and the hindgut. The foregut consists of the stomach and small intestine while the hindgut or large intestine is made up of the cecum and colon.
