What kind of stomach does a horse have

Saliva acts as a lubricant to provide easier passage through the esophagus and buffers acid in the stomach. Once swallowed the bolus of feed moves from the esophagus to the stomach. The horse has the smallest stomach in relation to body size of all domestic animals.

Due to the small capacity, smaller, frequent meals are recommended. Very little absorption of nutrients occurs in the stomach. Once feed is released from the stomach it enters the small intestine.

In the small intestine a majority of non-structural carbohydrate starch , protein and fat is digested by enzymes and absorbed. Read more. Mycotoxins are toxic substances produced by fungus.

Again, feeding high-quality hay and feeds will help maximize digestion in your horse's upper gut as well as help ensure he'll receive adequate nutrients to meet requirements. Although the microbial fermentation in the horse's hindgut does not yield the same nutritional benefits as in the cow's rumen, it does serve several important functions: VFAs from fermentation of?

The hindgut is also the major site of water absorption. Some minerals are absorbed from the hindgut, including phosphorus and some electrolytes. The microbes also synthesize several B vitamins, and those? Hindgut Problems The hindgut can also be a source of? The microbial populations in the cecum and colon are fairly sensitive to pH, and changes in the acidity of the hindgut can have devastating results in the horse, such as colic. This explains why sudden changes in feed can result in colic in horses.

For example, when a horse gets into the feed room and eats a large quantity of grain, there will be a sudden influx of? Under normal conditions of small meals of grain, most of the sugars and starch are digested and absorbed in the upper gut. But if a horse is allowed to overeat grain or other feedstuffs high in soluble carbohydrates, the sugars and starch can overflow from the upper gut into the hindgut.

This causes the microbial population in the hindgut to shift from mostly fiber-fermenting microbes to more starch-fermenting? The starch-fermenting microbes produce excess gas and lactic acid, resulting in a decrease in pH, which overall may lead to colic and possibly laminitis.

Another problem in the hindgut is simply due to the architecture of the tube. At one point? This area is at high risk for impaction of digesta, and many impaction colics originate at the pelvic flexure.

Finally, unlike many other species, the horse's intestine is not held in place by membranes, so it can move about and actually twist around itself and possibly other organs, further increasing the risk of colic. When horses are in their natural situation, wandering on thousands of acres, grazing throughout the day and moving freely, their digestive systems work fairly well with small amounts of forage moving through pretty much all the time.

But with the demands and constraints placed on horses by people, good feeding management is required to keep our horses healthy and comfortable. And the farther we take them from their natural environment, the more management-intensive we have to be to keep them healthy. Now that you understand how the gut is designed to work, the feeding management rules in the box below should make sense.

There are many more feeding management practices and rules for horses than those listed, but again, now that you understand the fascinating equine gut, you will hopefully never have to memorize a rule again. Feed small meals often. This helps your horse's digestive tract work most efficiently, as well as reduces the risk of digestive disturbances, such as colic. Feed no more than about 0.

This helps reduce the risk of soluble carbohydrate overload to the hindgut. When using feeds lower in sugars and starch than grain, you can increase the amount fed in a meal. Feed at least 0. Adequate fiber is necessary to keep the microbial population healthy and maintain proper hindgut function. Make feeding changes gradually. Minor changes can be made over three to four days, and major changes may need to be spread over a few weeks. Only use feeds designed and labeled for horses.

Feeds designed for other species will not meet horses' specific nutrient requirements and may contain substances that are toxic to horses.

Never feed moldy feed or hay to horses. Horses are more sensitive to many substances than most other species due to their inability to regurgitate. It is also important to maintain stability of the microbial population in the hindgut.

Young worked at Farmland Industries, first as equine nutritionist and horse feed program manager, and later as a business consultant and professional development trainer for Farmland's local member cooperatives. During her stay in Texas, Dr. Young also served as a faculty member in the Equine Science Section of the Animal Science Department, teaching courses in equitation, training and horse management.

Young has worked as a trainer and riding instructor for more than 30 years, and continues to do so in the Kansas City area. Horses normally consume 2 to 2. However, it has been estimated that horses on pasture 24 hours a day, can consume up to 3.

As the dry matter and nutrient proportion derived from grain increases, horses will reduce their total dry matter intake. In addition, abrupt incorporation of grain into a horse's diet will increase the lactate concentration and lower the cecal and colonic pH from 6.

Colic In the mature horse, the exit and entrance to the cecum blind gut with a capacity of about litres or approximately gallons are separated by only about 2 inches. Feed Intake Horses normally consume 2 to 2. Make changes in feed slowly over a period of days and be careful about "topping the horses up" with grain prior to an event.
