Colic in Horses

What is Colic in Horses?

The word “colic” in horse terms simply means abdominal pain. The source of the pain could originate from any location within the horse’s abdomen, from the intestines to an organ such as the stomach or liver. Most commonly, colic occurs due to part of the intestines becoming impacted or from being in an abnormal placement within the abdomen.

Colic is one of the most common emergencies seen in horses, which is why it is very important to understand what it is, the common colic signs, and what to do.

Types of Colic

马have long gastrointestinal tracts that are mostly unattached inside the horse's abdomen. This can lead to colic due todisplacementorentrapmentfrom part of the intestinal tract moving to a location inside the abdomen that is abnormal.

• Impaction colic

• Gas colic

• Spasmodic colic (overexcitement of intestinal contractions)

• Enteritis/infection

• Strangulation

Symptoms of Colic in Horses

马experiencing colic may exhibit the following signs:

• Looking at sides

• Biting or kicking flank

• Pawing the ground or air

• Laying down and/or rolling

• Fecal balls small, dry, or not produced

• 食欲不振

• Change in drinking behavior

• Increased heart rate

• Abnormal breathing

• Sweating

• Restlessness

• Dullness or lethargy

• Tacky or dry gums

• Abnormal colored gums

Causes of Colic in Horses

马may colic for a wide variety of reasons, depending on a number of factors and predispositions, such as age and lifestyle. For example, a geriatric horse is more likely to colic due to a mass causing a strangulation of the intestines, which leads to a blockage of the gastrointestinal tract. Young horses are more likely to colic due to an impaction from worms if they have not beendewormedappropriately.

Risk factors that could lead to colic include:

• Changes in diet (grain or hay)

• Changes in routine or exercise

• Weather changes

• Geriatric horses

• Young horses

• High parasite infestation

• Sand ingestion

• Overweight

• High grain diets/low forage

• Long periods between forage/feeding

• Decrease in water intake

• Dental issues

• Long-term use of non-steroidal anti-inflammatory medications

• Stress

How Veterinarians Diagnose Colic in Horses

Your veterinarian will be able to diagnose colic based on history, exam findings, and diagnostic tests. The most common signs a veterinarian will look for to diagnose colic will be signs of abdominal pain along with an elevated heart rate. The veterinarian will also want to pass a nasogastric tube through the horse's nose to the stomach to check for any reflux or backup of fluid that can signify intestinal blockage.

Another important diagnostic the veterinarian will want to perform is rectal palpation. By palpating through the rectum, the veterinarian is able to assess several organs and feel for any abnormalities, including an intestinal blockage or impaction.

Further diagnostic tests that may be recommended. Anabdominocentesisis performed to obtain fluid from the abdomen in order to assess for intestinal damage. An ultrasound may be used to look at internal organs. Lastly, a complete blood count and blood chemistry may be performed to evaluate organ function and inflammation.

Treatment of Colic in Horses

In order to appropriately treat a horse for colic, the underlying medical cause for the colic symptoms must be identified. Medical treatment may be performed at the farm, or it may be recommended to take the horse to a hospital for further evaluation, 24-hour care, and possible surgery.

Medical treatment for colic may include non-steroidal anti-inflammatory medication such as banamine (flunixine meglumine) to alleviate pain and inflammation. The administration of fluids, electrolytes, and/or mineral oil via the nasogastric tube placed in the horse's stomach may also help. If the horse does not improve with medications or treatments given on the farm, then hospital or surgical care may be required for treatment.

Colic surgery requires the horse to go under general anesthesia and have abdominal exploratory surgery to find and potentially fix the cause of the horses' colic symptoms. Colic surgery may not be possible for all horses due to the ability to get a horse to a hospital in a short amount of time and cost. Colic surgery can average between $5,000-$10,000 depending on the complications and severity of the colic. In severe colic cases, the recommendation may be euthanasia due to the horse having a very poor to guarded prognosis of recovery.

Recovery and Management of Colic in Horses

Recovery and management of colic all depends on the severity and medical reason for the colic episode. If the colic episode was minor and able to be resolved with minor medical treatment on the farm, the horse may be back to their normal lifestyle within a few days. If the horse required hospitalization and surgery, it could take weeks to months to recover. Typically, after a colic episode, the veterinarian will implement a slow refeeding schedule to make sure they have completely recovered and are not showing any more colic symptoms before they are allowed to go back to their normal feeding and exercise program.

Prevention of Colic in Horses

Reduce your horse’s risk of developing colic with the following recommendations:

• Access to fresh water at all times

• Pasture turnout

• Avoid feeding on the ground in sandy areas

• Feed grain and any type of pelleted feed only when necessary

• Monitor for colic symptoms especially during feed, exercise, or routine changes

• Routinedental careat least once a year by the veterinarian

• Routine parasite prevention: fecal egg count 1-2 per year as recommended by veterinarian along with a routinedewormingprogram

• Monitor any horses that have colicked previously, broodmares for the first two months after foaling, as well as horses taking any nonsteroidal anti-inflammatories such as bute or banamine
