It may flip forward, hook over the kidney, or even twist like a phone cord. This shift often leads to impactions and gas build up and cause more severe or prolonged pain. A tight colon twist can damage or kill the colon by stopping blood flow and oxygen availability. Large colon twists cause severe pain and illness as toxins enter the gut wall. This type of colic requires emergency surgery.
Older horses may get fatty tumors that can wrap around the small intestine and reduce blood flow. Parasites may move through the blood vessels and cause direct damage to the vessels and indirect damage to the gut. Colic may occur due to poor motility.
Poor motility may relate to infections in the gut or in the abdominal cavity. These horses often become sick due to toxins coming from the gut. If the process responsible for moving feed in the gut becomes disrupted, food may stop moving even if the path is clear. The gut will add fluid to the small intestine to try to move the food along.
If the gut continues to add fluid, the horse may become dehydrated and shocky. Overtime, fluid will back up into the stomach. Without relief, the stomach may burst. If poor motility occurs in the colon, gas will build up and lead to gas colic and maybe displacement. Walking can provide pain relief and encourage motility if your horse has cramps or is early on in colic.
Walking can also help prevent your horse from rolling. Rolling can injure you or your horse. A horse may become cast rolling in a stall or other small area. If your horse is uncontrollably thrashing, stay out of the way. Some types of colic are linked to fever. Horses with a fever are okay to walk while waiting for the veterinarian. Diseases such as pleuritis, tying up and laminitis may present signs similar to colic. Walking horses with these diseases will only make the disease worse.
In general, walk the horse if it makes them feel better. Stop walking if the horse seems worse or if you detect signs of rib pain, foot pain, or muscle pain. Never walk your horse or yourself to exhaustion. Mild, recently onset colic may improve by walking the horse, without a veterinarian. You should call a veterinarian if:. Your veterinarian may be able to determine how severe the colic is before arriving.
If safe, walk your horse to help motility and prevent rolling. Only walk if it makes your horse feel better, and never walk until you or your horse tire. Your veterinarian will assess your horse's heart status and identify signs of shock or toxemia.
Depending on your case, your veterinarian may then pass a nasogastric tube. This narrow, long tube runs from the nostrils to the stomach. This process can be a life-saving measure by preventing the stomach from bursting. Mineral oil and laxatives may relieve an impaction, and water can rehydrate your horse.
Both mineral oil and water can stimulate gut motility. A rectal exam allows your veterinarian to palpate the back half of the gut. Sometimes your veterinarian can feel an impaction. A rectal exam is always somewhat risky due to the potential of tearing the rectum. If the rectum tears, feces can enter the abdominal cavity and cause severe problems. A veterinarian should use a sedative or twitch for this exam.
Not every colic case needs a rectal exam. The test results can help determine if the horse needs surgery. If you take your horse to an equine hospital, a veterinarian may run blood work or perform tests such as ultrasound or radiographs.
Feed may add to an impaction. Grazing on a small amount of fresh grass may help stimulate motility. Your veterinarian may also have you walk your horse periodically to encourage motility.
Most cases will respond to this type of treatment within a few hours. Some horses may need additional fluids for rehydration or may need another exam. Your veterinarian may recommend a visit to a horse hospital equipped for abdominal surgery if the colic:.
Veterinarians will then decide if your horse needs surgery or continued treatment and close monitoring. Research suggests strategic parasite control is optimal; owners should contact their vets to design a program based on fecal egg counts and pasture management. Nonstrategic rotational deworming causes parasite resistance to anthelmintic parasite-killing drugs and is no longer recommended. DO take steps to reduce ingestion of sand. Keep hay off sandy surfaces by placing rations in a manger, cut-down garbage can or rain barrel ensuring there are no sharp edges , or on a cement pad or rubber mat swept clean of sand.
If your horse likes to pull his hay out of the container and eat it off the ground, lay mats around the container. DO check stool samples of horses prone to sand colic. Tap the bag and the sand will settle out in the lower corner.
If you get a negative, repeat the test three or four times over a three-day period to make sure. Keep your horse off sandy areas until the problem clears. DO consider gastric ulcer prevention methods for highly stressed horses or performance horses, per veterinary instructions, says Keenan. DO consider getting major medical not just surgical insurance to cover the costs of advanced medical and surgical care for your horse. It is not as expensive as you might think and can save you the stress of wondering where to come up with a large sum of money to save your horse.
Multiple smaller meals are generally better for the digestive tract than one or two large meals. No doubt about it, colic surgery is expensive. Be sure you discuss costs with veterinarians, even before going to the clinic.
You can also inquire about therapy options to keep costs down, she adds, as possible nonsurgical treatments are often available. Editor-in-Chief: Stephanie L. T he changes indicating colic were subtle but nevertheless concerning. Colic Fugaro, VMD, Dipl. While You Wait for Your Veterinarian. Keenan, DVM. If done incorrectly and the horse aspirates it into the lungs, he could die, warns Weatherly. Here are six feeding tips to reduce digestive upset: Provide an unlimited source of clean water.
Feed a consistent diet and make any changes slowly. Feed an appropriate hay and offer it free choice. Feed concentrates as small, frequent meals. Do not feed more than 4 pounds of concentrate per meal. Maintain a consistent daily feeding schedule. Its multi-pronged approach supports complete GI tract health, and reduces the risk of ulcers, digestive upset, and hindgut imbalances. Heading to the Equine Hospital for Colic Care.
DO trailer the horse , if possible, in a trailer without dividers. This reduces the chance of your horse getting cast under a partition, Weatherly says. However, many colicking horses trailer fine, and the confinement the divider provides seems to help.
This is something that needs to be thought through prior to an emergency. Administer medications correctly and follow the recommended protocol for the complete duration prescribed. If you have concerns, ask your veterinarian before making any changes. DO consider management changes if your horse has colicked before. Figure 4. Small intestine. The small intestine is attached by the mesentery, a thin membrane that allows the small intestine mobility in the abdominal cavity.
Impaction colic — the large intestine folds upon itself and has several changes of direction flexures and diameter changes. These flexures and diameter shifts can be sights for impactions, where a firm mass of feed or foreign material blocks the intestine including the cecum. Impactions can be induced by coarse feed stuff, dehydration or accumulation of foreign material like sand. Figure 5. Large intestine. Impaction colics are commonly located in the cecum and large intestine. Gas colic — all colics are associated with some gas build up.
Gas can accumulate in the stomach as well as the intestines. As gas builds up, the gut distends, causing abdominal pain. Excessive gas can be produced by bacteria in the gut after ingestion of large amounts of grain or moldy feeds.
A nasogastric stomach tube inserted by a veterinarian is used to relieve the pressure of the gas and fluid accumulation in the stomach. Spasmodic colic - defined as painful contractions of the smooth muscle in the intestines. Spasmodic colic has been compared to indigestion in people and is usually easily treated by a veterinarian. Over excitement can trigger spasmodic colic. Enteritis — inflammation of the intestine possibly due to bacteria, grain overload or tainted feed.
Horses with enteritis may also have diarrhea. Enteritis is often hard to diagnose and may present itself similar to displacement or impaction colics.
Treatment To give the proper treatment for colic, it is important to determine the cause, so that it can be corrected. The severity of the signs of colic is not necessarily indicative of the severity of the colic, and sometimes it is difficult to determine the exact cause and therefore the correct treatment.
For these reasons make sure to have a veterinarian evaluate your horse as soon as possible. Many cases of colic can be treated successfully with medication, while others involving severe impactions or twists may require immediate surgery. While you are waiting for your veterinarian, you should:.
Observe your horse and monitor vital signs as well as passing of any feces. Remove access to feed.
