Regular bowel movements are essential for a healthy digestive system, ensuring waste is efficiently expelled from the body. In horses, irregular bowel movements pose a significant risk of life-threatening colic.
When the stomach and intestines are not functioning optimally, or if feed is indigestible, feces can accumulate in sections of the intestine, leading to constipation or difficulty in defecation. If left unresolved, constipation can develop into impaction or bowel obstruction, a critical condition requiring urgent veterinary attention.
In cases of equine constipation, horses often struggle to pass manure, leading to hard, dry feces or a noticeable reduction in the frequency of defecation. [1] Constipation can result from inadequate water intake, poor diet, lack of exercise, or underlying health issues.
Constipation in horses requires prompt veterinary assessment since prolonged or severe cases can lead to serious complications, including colic. Understanding the causes, symptoms, and prevention strategies can help horse owners maintain their horses’ digestive health and overall well-being.
As a horse owner you likely know that monitoring your horse’s manure is an important way to assess their health. But what should you do if your horse is having trouble pooping? Constipation in horses can arise for many reasons from simple dietary changes to more serious underlying issues. When a horse can’t poop or strains to pass manure, it’s crucial to address the problem quickly.
In this comprehensive guide, we’ll cover the signs of constipation in horses common causes and steps you can take to gently encourage a bowel movement. With some helpful tips and natural remedies, you can get your horse’s manure moving again and avoid potentially dangerous complications.
What is Normal Pooping for Horses?
To start, it helps to understand what normal pooping looks like for a healthy horse. On average, horses pass manure around 6-12 times per day. The feces should have a semi-firm, moist consistency and medium brown color.
Signs your horse is pooping normally include:
- Producing manure several times daily
- Passing poop that is well-formed and moist
- Showing ease and comfort passing manure
- No signs of straining or discomfort
Deviations from their normal pooping pattern warrant a closer look. Monitor quantity, consistency, and your horse’s comfort level to catch issues early.
Common Causes of Constipation in Horses
When a horse can’t poop or strains to pass manure, it signals constipation. Here are some top reasons horses get “backed up:”
- Dehydration – Inadequate water intake leads to dry, hard feces that don’t pass easily.
- Poor quality hay – Overly coarse, stemmy, or dusty hay is harder to digest.
- Inadequate chewing – Dental issues prevent proper breakdown of feed particles.
- Lack of exercise – Reduced gut motility causes manure to accumulate.
- Medications – Some drugs like NSAIDs slow intestinal transit time.
- Discomfort/pain – Abdominal or rectal pain inhibits normal pooping.
- Sand accumulation – Ingested sand collects in the colon, causing impactions.
Figuring out the underlying cause, through diet analysis, exams, bloodwork, etc. helps target solutions.
Signs Your Horse is Constipated
Catching equine constipation early provides the best opportunity for quick resolution. Here are common indicators:
- Noticeable decrease in manure output
- Hard, dry, small feces
- Visible straining/pushing with no results
- Stomping feet, swishing tail, pacing
- Infrequent bowel movements
- Increased lying down due to discomfort
- Reduced appetite or interest in food
- Mild colic symptoms
Don’t hesitate to call your vet if symptoms persist or your horse shows signs of pain/discomfort.
Encouraging a Bowel Movement Naturally
For mild constipation, simple at-home remedies can get things moving again. Always consult your vet before giving your horse any new supplements or medications. Natural options include:
- Increase exercise to stimulate gut motility
- Provide unlimited fresh, clean water
- Add water to feed to increase moisture intake
- Offer bran mash to soften dry manure
- Add 1-2 tablespoons oil to feed to lubricate feces
- Feed soaked beet pulp to add moisture to digestive tract
- Try gentle abdominal massage to stimulate bowels
- Consider probiotic supplement to support healthy gut flora
Patience and gentle encouragement of natural elimination is ideal. However, contact your vet if no improvement in 12-24 hours.
When to Call the Vet About Constipation
While mild constipation may resolve on its own, more serious cases require veterinary intervention. Call your vet right away if your horse shows:
- Straining or discomfort without passing manure
- No bowel movement for over 24 hours
- Loss of appetite for 12+ hours
- Colic symptoms like flank watching or kicking at belly
- Distended, swollen abdomen
- Dullness, lethargy, or depression
Your vet can check for underlying illness and provide medical treatment as needed, such as IV fluids, laxatives, pain management, or sand-clearing agents. Don’t delay in severe constipation cases.
Preventing Constipation in Horses
An ounce of prevention is truly worth a pound of cure when it comes to equine constipation. Help minimize your horse’s risk with these proactive measures:
- Provide unlimited access to fresh, clean water
- Feed a high-quality diet with ample roughage
- Schedule regular dental exams
- Ensure regular exercise and turnout
- Monitor for signs of discomfort or pain
- Limit medications that slow GI motility
- Consider psyllium or beet pulp for added fiber
- Use probiotics to support healthy digestion
- Practice consistent parasite control
By being vigilant and responsive when changes arise, you can help your horse stay happy, healthy, and “regular” for years to come. Paying close attention to diet, hydration, exercise, and manure habits is key. If in doubt, call your trusted veterinarian right away. With prompt care, your horse can get back on track.
Signs of Constipation in Horses
Constipation in horses occurs when there is difficulty in passing manure due to slow or impaired movement of digested material through the intestines.
Recognizing constipation in horses involves observing various physical and behavioral signs. Key indicators include: [1][2][3][4]
- Tenesmus (straining): This is characterized by the horse straining to defecate despite producing little or no feces. The horse may exhibit repeated, forceful attempts to pass manure, which can cause discomfort and distress. Tenesmus often indicates irritation or obstruction in the rectum or lower gastrointestinal tract.
- Reduced Fecal Output: A noticeable decrease in the amount or frequency of manure passed is a common sign of constipation. The horse may produce less manure than usual or have fewer bowel movements per day.
- Abdominal Discomfort: Horses with constipation often show signs of abdominal pain (colic), such as restlessness, kicking at the belly, or shifting weight. This discomfort is due to the buildup of feces and pressure within the intestines, which can cause the horse to appear uneasy or agitated.
- Distended Abdomen: Swelling or bloating of the abdomen can occur as a result of fecal accumulation. The abdomen may appear enlarged and tense, which is a visible sign of gastrointestinal distress and may indicate an obstruction or severe constipation.
- Frequent lying down: The horse may lie down more frequently than usual as a response to abdominal pain or discomfort. This behavior, often seen as an attempt to find relief, can be accompanied by periods of restlessness or getting up and lying down repeatedly.
- Reduced Appetite: A decrease in a horse’s interest in food or reluctance to eat can be a sign of constipation.
Trauma, Tumours or Surgery
The horse’s gastrointestinal tract can narrow due to trauma, tumors, or previous surgery, restricting the normal flow of feed material. [4]
Trauma from injury or severe inflammation can cause scarring that reduces the intestinal space, impeding digestion. Tumours, or neoplasia, may develop within or near the intestines, blocking or compressing them. [15]
Surgeries on the gastrointestinal tract can lead to scar tissue or adhesions, bands of fibrous tissue that form between internal organs or the abdominal wall after surgery, which narrow the intestines.
These narrowed areas can create blockages, leading to impaction. Horses with these conditions may face ongoing digestive issues, requiring careful monitoring, dietary adjustments, and sometimes further surgical intervention.
Other possible causes of equine constipation include: [4][16][17][18]
- Foreign Materials: Ingested foreign objects can cause physical blockages in the gastrointestinal tract, leading to constipation. Materials may include bailing twine, hay nets, bedding, sand, or fibers from feed sacks.
- Pain After Foaling: After foaling, mares often experience abdominal and pelvic pain, which can reduce their willingness to defecate. This discomfort can lead to straining or reluctance to pass manure, contributing to constipation.
- Medications: Certain medications can affect intestinal motility and contribute to constipation.
- Not Eating: When horses do not eat enough, their digestive system may lack the necessary bulk to stimulate normal bowel movements.
Impaction colic is closely linked to constipation in horses, occurring when a blockage forms in the intestines due to the buildup of feed material, sand, or other indigestible substances. Blockages disrupts the normal passage of digestive contents, leading to significant pain and discomfort. [6]
Horses suffering from impaction colic typically show signs of abdominal pain, such as pawing, rolling, or frequently lying down. They may also exhibit reduced manure production, reluctance to eat, or changes in behavior. [4]
If left untreated, impaction colic can lead to severe complications, including intestinal damage or rupture, making it a potentially life-threatening condition. The risk of a horse developing constipation or impaction can be greatly minimized with proper management. [4]
Effective treatment for constipation in horses involves a multifaceted approach depending on the severity of the condition and the needs of the horse. Promptly addressing constipation offers the best chance of preventing complications like impaction colic.
Administering fluids is a primary treatment for constipation. Fluids and electrolytes can be given orally, intravenously (IV) or through a nasogastric tube to help rehydrate the horse and soften the fecal material in the intestines. [4]
Rehydration is essential for restoring proper bowel function and easing the passage of impacted material. Fluid therapy also helps maintain hydration and electrolyte balance, which is critical for normal gastrointestinal motility. [19]
