What does a horses cecum do?

What is the purpose of the equine cecum?

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 function of the ileum and cecum?

The ileum, or last part of the small intestine, enters into this large organ, which can hold up to 8 gallons of material. The cecum takes up much of the right half of the abdomen, reaching from the pelvic inlet to way up along the rib cage. The equine cecum serves as a storage site for water and electrolytes.

Why does a horse need a ileum?

The additional water adds some weight to your horse, but it helps replace crucial electrolytes lost from heavy sweating. The ileum expels food material into the cecum, using contractions and vascular distension to prevent any backflow.

What is the function of the equine cecum?

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.

How does a horse’s diet affect the cecum?

The horse’s diet provides the microbes in the cecum with an energy resource unusable by the horse. In turn, the end products of the microbes’ metabolism provide the horse with an energy resource. When a horse’s diet changes, so does the composition of the microbes in the cecum.

What is the function of the cecum and large intestine in horses?

Function and Health of the Horse’s Cecum and Large Intestine. The horse’s digestive system is made up of several organs, each of which provides an important function in digesting and utilizing the nutrients that are in the feed and forage ingested by the horse.

What is ileus in horses?

Disruption of this intricate interaction leads to stasis of aboral movement of food material, also called ileus. Unfortunately, this is a common and often fatal problem in the horse. A variety of prokinetic agents have been used in the horse with variable success.

What is the function of the large intestine in a horse?

The mature horse’s large intestine makes up more than half of the total volume of the digestive tract, is important for microbial digestion of food and is a major reservoir for water. The foal and growing horse have undeveloped cecal and colonic digestion as compared to the adult horse.

Can erythromycin be used to treat ileus in horses?

In the equine patient with ileus, erythromycin may be a useful prokinetic drug. Currently, it is most commonly used for treatment of cecal impactions (64). However, before making any assumptions, it is important to further elucidate the mechanism of action of erythromycin in the horse. Additional studies, including clinical trials, are needed.

What do bacteria do in the cecum of a horse?

Some bacteria in the cecum are capable of decarboxylating amino acids, which provide a source of nitrogen for the horse. (Bailey) Certain bacteria are also able to create vitamins, such as vitamin B, for the horse’s use.

What is the function of the cecum in a horse?

The cecum of the horse performs the same functions as the rumen of the cow and sheep and is the major area of microbial digestion. Microorganisms present in the cecum are capable of digesting fibrous feed producing a major energy source, the volatile fatty acids.

Why dissect the equine GI tract?

In this three part series we dissect the equine gastrointestinal (GI) tract to gain a better understanding of the digestive process and learn how we should keep our horses, and what feeding management we should follow to maintain optimal (digestive) health in our horses.

What happens when your horse’s cecal bacteria die?

As these bacteria die, they release endotoxins that enter the bloodstream and can cause severe issues with your horse. Even a planned change from an all- or mostly forage diet to a fair amount of grain will cause a shift in cecal bacteria and pH.

What is the largest portion of the horse’s digestive system?

The largest portion of the horse digestive system is the large intestine. After ingesta passage from the cecum, it enters the large intestine, specifically the large colon.

What is the best drug for ileus in horses?

When humans are given dopamine as a drug therapy, ileus is a side effect. It appears that antidopamine medications can block this. In a small study of horses with the condition, the drug metaclopramide, which blocks the effects of dopamine, was shown to be effective in the treatment of ileus.

What happens after colic surgery on a horse?

Complications are particularly frustrating to equine surgeons. It is very hard to help a horse come through a difficult colic surgery, only to see it succumb in the postoperative period. One of the worst of these complications that can kill horses is called postoperative ileus (lack of gut motility).

How is ileus characterized in humans?

In humans, when using the duration of clinical signs for classification, ileus can be characterized as either adynamic (30), resulting from short-term alterations of gastrointestinal motility, or paralytic, when motility is lost for longer than 72 h (31).

What is postoperative ileus in horses?

One of the worst of these complications that can kill horses is called postoperative ileus (lack of gut motility). Scientists aren’t exactly sure what causes it, or why one horse will recover from surgery while another will develop ileus following the same surgical procedure.

What goes through a horse’s stomach first?

Anything the horse eats goes first to the stomach and then to the small intestine. Material not digested in the small intestine passes through the ileo-cecal orifice into the cecum and then to the large intestine.

Can you give erythromycin to horses?

Erythromycin can be toxic to smaller animals like guinea pigs, rabbits, gerbils, and hamsters, and therefore, should not be given to them. Similarly, this antibiotic should not be prescribed for cattle or adult horses.

What is the best antibiotic for rheumatoid arthritis in horses?

Antibiotics such as erythromycin, clarithromycin, and azithromycin can be used to treat R. equi infection in horses, but they can also result in potentially serious side effects such as diarrhea and overheating (hyperthermia). Resistance of the bacteria to some antibiotics (macrolides) has also been reported.

What is Rhodococcus equi in horses?

Rhodococcus equi is a bacterium that lives in the soil and can cause pneumonia in young (1 to 6 months old) foals. In rare cases, immunodeficient adult horses and humans can also become infected.
