Horse folk refer to a "drawn up" horse as one with a sunken or shrinking flank or belly. The abdomen seems pushed up if the moist feed material dries up and shrinks. The contents of the intestine are in direct touch with the bloodstream. The colon is crucial to the horse's water balance. As the level of moisture in the diet decreases, so does the amount of liquid the colon absorbs from the digestive tract. This leads to increased amounts of feces (poop) being passed along.
The most common cause of a drawn-up horse is excessive dry matter in the diet. The volume of food consumed by a horse should be sufficient to meet its nutritional requirements but not so much that it causes bloat or diarrhea. A horse can lose water through respiration, sweating, urine, and feces. It is important that enough water is available for the horse to drink but not so much that it causes diarrhea. Diarrhea can lead to weakness and dehydration because you will be losing water through both urine and feces at an accelerated rate.
If your horse is eating a high-forage diet then it is likely that they are suffering from the "dried out" look. High-forage diets contain more fiber than other types of diets, which means that your horse has more work to do to digest it.
A horse's esophagus enters the stomach at a significantly lower angle than that of other animals. When your horse has indigestion or bloating, the stomach pulls on the valve, forcing it to stay closed. As a result, vomiting is almost impossible for horses. If you discover your horse vomiting, stop what you're doing and remove any food from his environment. Also, make sure he isn't suffering from pain or discomfort otherwise he might want to escape by throwing up.
If your horse is eating and acting normal but still throwing up, there could be another cause. For example, if he had something in his mouth when he threw up (such as a stick or piece of hay) then his throat would be damaged. In this case, call your vet immediately so they can take care of him.
Last but not least, don't panic! Indigestion is very common in horses and usually doesn't require medical attention unless you see signs of pain or discomfort. Simply stopping whatever caused the problem in the first place should be enough to fix it.
Horses, like humans, do not vomit. The reasons for this are tied to their physiology and anatomy. According to Equus magazine, the esophageal sphincter in horses is significantly stronger than in most other species, making it harder for it to open under rearward pressure from the stomach. This prevents horses from vomiting.
If a horse does puke, it's because something has gone wrong with its digestive system. The first thing to go wrong is the lining of the stomach itself. If it starts to wear away (as it does in some people who drink too much alcohol), food may be able to get into the muscle layer of the stomach, where it irritates and inflames it. This condition is called gastritis, and if it isn't treated it can lead to ulcers.
The next thing that goes wrong is having nothing to digest. Because horses don't have human digestive systems they are dependent on bacteria in their gut to break down food into nutrients that can be absorbed through the intestinal wall into the bloodstream. If these bacteria are unable to do their job, then food passes through the intestine undigested which can cause problems for the horse when he comes into contact with large amounts of it (for example if it lies around as manure).
Finally, there are two things that can stop a horse from throwing up: pain or being scared shitless.
Many horses become overly reliant on the bit because the rider does not demand enough impulsion or strength. In this scenario, you must "Power Up"! If there isn't enough energy, the horse is likely to be long in the body and the hind legs aren't below the body. This is referred to as being "strung out." When you give the command to walk, your horse should respond with a quick, eager gait. If it's not quick enough, increase the pressure on the reins until it is.
Horses can also become overweight or injured and need help getting back into shape. Or, they may simply be too old for their jobs and should be retired. Either way, you will need to work with your veterinarian to determine the cause of the problem before developing any treatment plans.
The horse's coccyx is represented by the tail. When you fall on your tailbone, you suffer a severe injury. The horse balances itself by using its tail. Movement keeps the tail flowing. If it was not for this wonderful appendage, many of them would be injured or even killed.
The horse has two types of muscles in its tail: smooth muscles and skeletal muscles. The smooth muscles control the movement of the tail. They are also responsible for its flexibility. The skeletal muscles help the horse maintain its balance. They are also used to signal its presence or absence in dangerous situations. For example, if a horse is about to be hit with a car's bumper, it will raise its tail to warn others.
Horses have three types of bones in their tails: dorsal, sacral, and caudal. The dorsal vertebrae protect the spinal cord. They are also involved in body support because they provide strength for the back. The sacral bones form the base of the spine. They are also important for balance because they connect to the ilium (an oval bone located between the legs) which helps the horse keep its center of gravity over its base. The caudal vertebrae end in sharp points that help the horse retain its balance when jumping or running.
