What To Give A Horse With Diarrhea? (TOP 5 Tips)

In a healthy, well-hydrated horse, this will be two seconds or less. For mild diarrhea, you can add Pepto Bismol (bismuth subsalicylate) to your horse’s daily ration. Give this at about five ounces (10 tablespoons) at a time, but don’t overdo it.

) to your horse’s daily ration. Give this at about five ounces (10 tablespoons) at a time, but don’t overdo it. This is most easily given via a plastic dosing syringe.

What to do if your horse has diarrhea?

  • Fecal samples can reveal infectious causes,such as coronavirus,Salmonella,C.
  • Blood tests reveal hydration level,electrolyte balance,blood proteins,and pH.
  • Ultrasound can reveal thickened intestines,pinpoint specific segments of affected bowel,and identify abscesses,enlarged lymph nodes,or excess or infected fluids around the intestines.

What to feed a horse that has diarrhea?

To treat an adult horse suffering from diarrhoea, you should:

  1. Stable the horse.
  2. Feed good hay but no lush grass, which may exacerbate the problem, and provide plenty of water.
  3. Avoid feeding concentrates and consider the use of probiotics to encourage the growth of healthy gut flora.

What does it mean when a horse has runny poop?

Diarrhea may represent a simple digestive ‘upset’, e.g., following a sudden change in diet, when it causes no other significant illness. When caused by infection, intestinal parasitism or other significant gastrointestinal or metabolic abnormality, the horse may be clinically ill and need veterinary attention.

How can I firm up my horses poop?

If your horse’s manure is dull, dry or hard, he may be dehydrated, and you will need to increase his fluid intake immediately. If that’s the case, you can try soaking hay, pellets or cubes in water or provide him with a soggy bran mash.

How long can a horse have diarrhea?

Frequently, diarrhea may last for a day or two, resolve on its own, and you may never find the reason it occurred. But in some cases, it can be extremely acute and severe or become chronic and require ongoing treatment and vigilance.

How do you stop diarrhea in older horses?

Diet plays an important role in managing the loose manure. I try to keep the horse on a combination of beet pulp, well soaked hay cubes, and a complete senior diet, avoiding long-stem hay altogether. This can be challenging as it is often hard to keep weight on these guys.

What helps diarrhea in older horses?

Treating equine diarrhea Acute, severe cases are best treated in a hospital setting with access to intravenous fluids, along with acupuncture, probiotics, fecal transplants and antibiotics if needed. In some cases, the antibiotics are the cause of severe diarrhea and the treatment needs to be done without them.

Can worms in horses cause diarrhea?

Parasitic worms live in the intestines of horses and ponies. Small numbers of worms can be tolerated, causing no effect on well-being. Larger worm burdens can cause a range of problems including ill thrift, diarrhea, colic and death.

Will beet pulp help diarrhea in horses?

Beet pulp is good for horses with diarrhea. Beet pulp is often considered a good way to treat diarrhea in horses. To counter the effects of diarrhea, you need a feed that is high in fiber and dry content. This way, the excess liquid in the stomach that causes diarrhea becomes concentrated.

Can too much hay cause diarrhea?

When new hays are introduced, this can alter the microbial populations in the cecum and colon which can cause diarrhea. Make changes gradually over a one-to-two-week period. These include changing your horse’s forage or hay type, switching their concentrate source, or even adjusting mealtimes.

What is a good probiotic for horses?

Probios® Powder. Probios Powder is a probiotic supplement for horses and dogs that contains guaranteed levels of Lactobacillus plantarum, Enterococcus faecium, Lactobacillus casei, and Lactobacillus acidophilus. Probios is the world’s most widely recognized, researched, and used brand of DFM (direct-fed microbial).

Can horses get diarrhea from stress?

When a horse is stressed, they may produce more manure than usual in a short period of time and may also experience diarrhea. Horse diarrhea can also be caused by a poor diet, which is a common cause of stress in horses.

Can Dewormer cause diarrhea in horses?

However, deworming your horse can cause stress and a shift in the microbiome of the gut population. Often, this can result in digestive upset in the form of diarrhea, going off feed or mild colic.

Dealing With Diarrhea

You may be able to work through minor diarrhea on your own for a day or two if you follow our recommended remedies: The following products are credited: Pepto-Bismol, Ration Plus, Psyllium, Live Culture Yogurt, Saccharomyces, Bio Sponge Thinkstock Animal parasites, such as those that could be found in crowded fields of horses, are a common cause of diarrhea. If your horse exhibits any signs of dehydration or deterioration, call your veterinarian immediately. If you see any of the following symptoms: bloody diarrhea, profuse watery diarrhea, loss of appetite, fever, or a foal with diarrhea, contact your veterinarian immediately.

It is more difficult to keep your horse clean and dry in the warm weather, and it is even more difficult in the chilly weather to keep your horse clean and dry.

Whatever the reason of your horse’s diarrhea, there are certain fundamental care methods that you may employ to alleviate the situation:

  • Thoroughly clean the buttocks and hind legs of your horse.
  • Tails should be braided to keep long hairs out of any diarrheal fluids
  • Apply diaper-rash ointment or petroleum jelly to the affected region to keep it from becoming inflamed.

The First Steps It can assist you in reducing your horse’s feed intake. Continue to offer hay/roughage, but if you’re providing high-protein alfalfa, consider switching to a hay that is primarily grass. It is critical to ensure that your horse has access to enough of fresh water in order to prevent dehydration from occurring. Clean and refill water buckets and tubs on a daily basis. Any horse suffering from diarrhea should be isolated, both for the sake of preventing the spread of dangerous disease and so that you can keep track of how much fluid your horse is consuming (see below).

  • Pinching the skin around the neck or lightly pinching the skin around the eyelid is a quick and easy approach to check.
  • When a horse is dehydrated, the skin will remain puckered up for a period of time before eventually flattening.
  • Gums that are in good health are pink and wet to the touch.
  • This is referred to as CRT, which stands for capillary refill time.
  • If your horse has minor diarrhea, you can give him Pepto Bismol (bismuth subsalicylate) as part of his regular feed.
  • This is most conveniently administered with the use of a plastic dosage syringe.
  • This medication can be taken three to four times each day, depending on the individual.

To put it another way, if you don’t want to take the chance of impaction, don’t drug your horse and then turn him loose in a 20-acre pasture where you won’t know what his excrement looks like.

In addition to firming up manure and binding to some of the toxins generated by bacteria, such as the different clostridia, Bio-Sponge (di-tri-octahedral smectite) can be beneficial in certain diarrhea situations.

Activated charcoal may also be administered in order to aid in the absorption of poisons.

Psyllium, a supplement for sand colic, is also beneficial for diarrhea and feces-like discharge.

It is detrimental to feed it on a consistent basis since your horse will react and adapt to the increasing fiber content of psyllium with time.

Using probiotics to treat diarrhea problems has received a lot of attention in the medical community.

Many horses have benefited from Ration Plus.

You might also try Saccharomyces boulardii or live culture yogurt as alternatives (not all grocery-store products are live culture).

The idea here is to “seed” some beneficial bacteria into the stomach in order to reduce the quantity of poisonous bacteria in the gut, which may be the source of the diarrhea.

Even if you believe you are keeping your horse’s diarrhea under control and restoring his gut flora to normal, you should consider having a fecal sample tested for confirmation.

If you bring in a sample, be sure to bring in your deworming schedule records as well so that your veterinarian may make treatment suggestions.

When it comes to foals, you need to be on the lookout for Lawsonia, Clostridia, Rhodococcus, and Rotavirus.

Don’t resent having to collect the samples.

If the problem is parasites, you will need to modify your deworming program.

Deworming is frequently used as a first step in the treatment of many diarrheal illnesses, particularly when tiny strongyles are suspected.

Rotaviral immunizations are not included in the AAEP core vaccines, but if you have a problem on your farm, you should include them in your vaccination plan.

When working with foals, keep in mind the possibility of foal-heat diarrhea.

Don’t forget about your diet.

Simply reducing the amount of time spent on pasture may help to firm things up.

Many antibiotics have the potential to create bacteria in your horse’s stomach as a result of a shift in the bacteria in the horse’s gut.

NSAIDs (nonsteroidal anti-inflammatory drugs) are also known to cause diarrhea.

If you have one horse in the barn that has been diagnosed with Potomac horse fever, you must evaluate how and why that horse got exposed to the disease.

It is believed that the lights attract the insects that are implicated in the transmission of this ailment, although this has not been proven.

Diarrhea that is contagious It is necessary to take additional measures when your horse has been diagnosed with an infectious cause of diarrhea, such as Salmonella.

Isolate the horse as much as you possibly can.

Putting your other horses out during the day and then leaving the sick horse out in the same pasture at night is not going to assist the situation.

At the very least, dunk such instruments in a pail of disinfectant and put them out in the sun between horses if you are unable to do so.

If at all feasible, you should use gloves or thoroughly wash your hands before applying hand sanitizer to your hands.

It’s important to think about which horse will be next door if you don’t have enough stalls to put an empty one next to the sick horse.

Rubber boots are a must-have item for every horse person’s wardrobe.

If you don’t have access to a superior disinfectant, Clorox bleach will suffice.

Rather than continuing to treat symptoms, it makes much more sense in the long run, both for the health of your horse and your financial situation, to identify the underlying problem and then treat or eliminate it rather than merely treating the symptoms.

Start therapy as soon as possible with the recommendations provided below, but any signs of deterioration or dehydration necessitate veterinarian intervention. Cause-and-effect tests Treatments/Conditions

Diarrhea In Horses

Diarrhea is characterized by the generation of stools that are softer than normal in consistency. Equines’ normal excrement is generated in formed, non-offensive smelling, greenish-brown, semi-solid pieces that will break apart in the palm, showing varied degrees of fiber material according on the horse’s diet. Difficulty in forming stool varies from non-formed (‘cow-pat’) to liquid (like colored water), and there may be an objectionable smell associated with diarrhea. There are two types of liquid diarrhea: those that appear to be generated involuntarily in a projectile fashion (‘pipe stream’) and those that involuntarily flow down the hind legs (incontinence), resulting in the skin being scalded.

What is the significance of diarrhea?

Diarrhea is a rather frequent ailment in horses, and it is usually a transitory illness. The structure of the adult gastrointestinal system is such that disorders that affect the large bowel and cecum are more likely to result in diarrhea than conditions that affect other parts of the tract. Small intestinal problems can develop in foals before their big bowels are completely functional, which is usually before three months of age. When this occurs, foals can become extremely unwell very rapidly.

Equine clinical illness can result from infection, intestinal parasitism, or other serious gastrointestinal or metabolic disorder, and the horse will need to be sent to the veterinarian for treatment.

If your horse is suffering from diarrhea, consult your veterinarian.

What causes diarrhea in adult horses?

It is common for horses to heal before the reason of their adult equine diarrhea has been identified. ‘Regular’ bacteria of many different varieties are found in huge quantities in the horse’s intestines, particularly in the large intestines and cecum, and these bacteria are necessary for the horse’s normal digestive processes to take place. A abrupt change in food or antibiotic treatment might upset the natural ‘balance’ of these bacteria, causing digestion to become disrupted and diarrhea to ensue.

  1. Treatment with probiotics (discussed below) may aid in the rapid restoration of normalcy and, if administered early, before diarrhea occurs, may even be effective in preventing diarrhea.
  2. Salmonellosis (infection with Salmonella spp.
  3. Some symptomless carriers of salmonellosis first show signs of diarrhea after receiving antibiotics or being sent to the hospital for surgery.
  4. Only in rare cases may other bacteria, such as Clostridium spp., cause acute enteritis (inflammation of the small intestine), which can be deadly if not treated promptly.
  5. Horses suffering with intestinal parasites, the most serious of which is related with cyathostomiasis, are prone to diarrhea, especially in their younger and more debilitated counterparts.
  6. While encysted, they do not cause any difficulties, but during migration and, in particular, during emergence, they inflict significant damage to the lining of the large intestine, which can be fatal.
  7. As a result of the stress associated with long transportation in hot conditions, general anesthesia, and surgery, colitis (colon inflammation) may develop.
  8. Horses suffering from acute colitis are in critical condition and require intensive treatment.
  9. Lower-grade stress, such as ‘nervousness’ before a performance, can result in loose feces or even diarrhea in certain persons, as has been widely documented to occur in some individuals.
  10. Both of these conditions can cause damage to and dysfunction of the intestines, resulting in a failure of water absorption by and a loss of protein via the intestines, respectively (malabsorption syndrome).

This results in the production of watery feces and the increasing loss of weight in afflicted horses, which can be life-threatening in extreme cases.

How are the causes of diarrhea diagnosed?

The majority of the time, it is clear when a horse is suffering from diarrhea; nevertheless, pinpointing the reason is sometimes challenging. A veterinarian will perform a clinical examination and take a history, which will include information about the animal’s medical and worming history, the duration of diarrhea and dietary changes, exposure to stress, surgery, or other medical treatments, and any previous history of other illnesses, among other things. It is possible to collect blood and fecal samples for testing in the laboratory.

A rectal biopsy may be performed if it is deemed necessary.

If the condition is persistent or severe, it may be required to obtain large or tiny intestine biopsies, which can be done either by laparotomy under general anesthesia or laparascopically while the horse is still standing.

How is diarrhea treated?

Many instances of diarrhea in adult horses are caused by temporary digestive problems that do not necessitate treatment and resolve within a day or two after onset. If the diarrhea is severe or if the symptoms linger, medical attention should be sought. It may be important to begin treatment prior to obtaining a definitive diagnosis of the underlying cause. Green grass, rich feed, and antibiotic therapy are examples of symptomatic treatment that includes eliminating any evident cause or worsening issues such as excessive grass.

  • Always have a backup supply of drinking water free of electrolytes on hand in case the horse does not enjoy the flavored water as much as you do.
  • Activated charcoal, montmarillonite, bismuth subnitrate, codeine, and kaolin are examples of intestinal absorbents and anti-diarrheals that can be delivered through a stomach tube as needed to treat diarrhea.
  • Once the source of the diarrhea has been identified, a particular therapy should be implemented.
  • In addition, because they are frequently highly emaciated and secondary infections, these patients may want substantial nutritional (particularly protein) and hydration supplements, as well as antibiotic therapy.
  • In addition to these disorders, granulomatous enteritis and neoplasia are two others that require particular therapy and care.
  • As a result of the massive loss of fluid and electrolytes, along with the decreased digestion and absorption, and the increased protein loss caused by intestinal inflammation, it is possible to lose a significant amount of weight and become debilitated in a short period of time.

In this case, the horse is considered to be infected with a parasite. The poisons can cause irreversible damage to the big intestine blood supply, resulting in the death of the gut wall. As a result, these horses go into shock and die or require euthanasia very soon, despite therapy.

How is diarrhea prevented?

Diarrhea is best avoided by careful management, which includes the supply of high-quality pasture and feed, as well as the progressive introduction of new foods into the diet. It is vital to implement a strategic parasitic worm control program that is appropriate for the management situation, including twice-yearly (spring and fall) anthelmintic dosage that is targeted primarily at tiny strongyle worms (cyathostomes) and tapeworms, as well as other parasites. Contact with known carriers of Salmonella spp.

Although it is impossible to foresee which horses would develop diarrhea or colitis following stressful circumstances or situations such as competitions or surgery, it is always a good idea to be on the lookout for signs of these illnesses or situations in advance.

When should I call my veterinarian?

If your horse seems poorly (depressed, dehydrated, acting erratically or in pain), if the mucous membranes of the eyes and mouth are congested (red rather than pink), or if the diarrhea has continued for more than 2-3 days, you should contact your veterinarian.

The Scoop on Runny Poop: Diarrhea in Horses – The Horse

The physical (dys)function in question is a terrible and disgusting one. In addition, while it may be the cause of hysterical laughter among little children and the subject of snickers among adults, it is no laughing matter to horse owners. Whenever the gut fails to absorb electrolytes and water as it should, diarrhea ensues, and the electrolytes and water are allowed to escape out of the body as loose or watery stools. It can be either acute or chronic in nature. While certain varieties of horse diarrhea are not life-threatening if they are observed properly, others can be fatal if not treated promptly.

What Causes Diarrhea?

Diarrhea can be caused by a wide range of illnesses, some of which are not even connected to the digestive tract at all. While some horses have slight diarrhea when their food is altered, this is usually not a cause for concern. However, when poisons, sand, parasite larvae, and infectious agents like as germs and viruses are introduced, the situation becomes even more problematic.

Infectious Causes

Bacteria are a major cause of contamination. There are several ways that hazardous bacteria might enter the horse’s system. Sometimes something disturbs the balance of naturally occurring bacteria, causing “bad” bacteria to proliferate and eventually overpower the healthy bacteria. Salmonella and Clostridium species are the most often encountered bacterial pathogens. In Wellington, Florida, Dr. Peter Heidmann, DVM, of the Palm Beach Equine Clinic, states that the majority of Salmonella species are related with animals and birds.

  1. Horses can also have Salmonella and show no signs of illness, allowing them to spread the disease to one another,” he says.
  2. Clostridium difficile, which is found in the environment, gains a footing in the horse’s gut flora when the horse’s gut flora is imbalanced, which is frequently caused by the horse receiving antibiotics for another infection.
  3. The bacteria Clostridium perfringensis is a common cause of foal diarrhea in horses.
  4. Infections with Neorickettsia risticii, the causative agent of Potomac horse fever (PHF), are found in parasites that infect freshwater snails, caddisfly and may fly larvae, among other things.
  5. Neorickettsia was initially thought to be limited to the Potomac River region in Virginia and Maryland, but Heidmann believes it is endemic in other parts of the United States and suggests that you consult with your veterinarian regarding its incidence in your area.

As Nolen-Walston points out, “these horses develop high fevers when compared to horses suffering from other types of diarrhea,” and “while complication such as laminitis is always a serious possibility with any type of diarrhea,” she adds, “with Potomac horse fever, you often notice laminitis before you notice the diarrhea.” Coronavirus, which Nolen-Walston describes as “quite recently characterized in horses,” is frequently found herdwide, according to Nolen-Walston.

A very high temperature, moderate diarrhea, and/or colic are all possible clinical indications of the condition.

As Heidmann points out, “Coronavirus causes intestinal lining destruction and can lead horses to become quite ill.” In order for the body to reline the intestine, it must do so rapidly.

In contrast to bacterial infections, you can’t treat the organism directly since there aren’t any medications that are effective against coronavirus in horses.”

Inflammation and Toxicity

An NSAID toxicity, also known as right dorsal colitis (inflammation of the right dorsal colon or large intestine), is a condition that can occur after taking a particularly high dose or reacting adversely to an appropriate dose of non-steroidal anti-inflammatories (NSAIDs) such as phenylbutazone (Bute) or flunixin meglumine (Banamine). Specifically, Nolen-Walston explains that “the right dorsal colon gets swollen and ulcerated, which might induce moderate diarrhea and extremely low protein levels.” Chronic diarrhea is a symptom of inflammatory bowel disease (IBD), which arises when abnormal cells invade the lining of the small intestine, much as it is in humans.

A kind of cancer known as gastrointestinal lymphoma (GI lymphoma) occurs when lymphocytes (a type of white blood cell) enter the intestines.

As Heidmann points out, “sand is irritating to the intestinal lining and can cause harm due to its weight as well as abrasion.” When sand is cleared out of the intestine by restricting additional consumption and maybe employing psyllium to bond with the sand, the colon can typically re-establish its normal function and lining.”

Parasitic Causes

When little strongyle (cyathostomin) larvae burrow into the colon walls, a condition known as larval cyathostomiasis occurs. This cyclical phenomenon occurs in late winter to early spring, when they appear all at once and cause the horse’s gut walls to leak protein-rich fluid, producing diarrhea and low blood protein levels in the horse. Since it is the larvae that cause sickness rather than the adults,” Nolen-Walston explains, “a fecal egg count is not relevant for diagnosing the condition.” There is no relationship between the amount of larvae and the number of adult females who deposit their eggs.

The most effective therapy is moxidectin, which is the only dewormer that is guaranteed to kill the larvae.”

Causes in Foals

It is highly typical for foals to get heat diarrhea in the first week or two after birth, according to Nolen-Walston. “It appears to occur when the mare is in the process of giving birth to a foal, but no one is sure what is causing it,” she explains. These foals are alert and eating well, and the diarrhea is not severe at this time. If a foal owner notices that a foal has more watery fluid (rather than wet or liquid feces), or that a foal appears dull or has a fever, this is not consistent with foal heat diarrhea, and the owner should contact their doctor.” According to Nolen-Walston, Rhodococcus equiis an exceptionally prevalent pathogen in foals, with its most prominent symptom being lung abscesses.

Infected horses excrete Rhodococcus, although healthy foals can excrete the bacteria even if they do not have clinical illness.

Among foals, rotavirus is the most prevalent viral cause of diarrhea, particularly in foals between the ages of one week and two months.

According to the veterinarian, “(the foal) stops producing lactase, the enzyme that digests milk, which causes fluid to leak out of the body into the intestines, resulting in the foal becoming dehydrated.

The foal must be quarantined, and PPE (personal protective equipment for handlers) and biosecurity must be implemented.”

Self-Treat or Call in a Pro?

It is OK to reward oneself from time to time. Heidmann explains that a change in feed, such as switching from grass hay to alfalfa, is “not a major concern” and that the horse may have loose stools (also known as ‘cow plop’) but will still be healthy. If it persists for 24 hours or longer, or if the horse is unwell, we begin to be concerned that they are losing water, protein, and electrolytes through their feces,” says the veterinarian. That can be replaced by supportive treatment (your veterinarian supplying IV fluids to rehydrate the horse while also balancing electrolytes, injecting plasma to replace protein lost due to lack of absorption, and regulating pH).

“The most essential thing to understand about horses is that there are a handful of things that happen,” Nolen-Walston continues.

Therefore, any horse that has highly watery diarrhea should be evaluated that day, especially if the horse is dull, has a reduced appetite, or its gums are red or purple instead of the typical pink.”

Diagnosis: FrequencyImportance

The majority of the diarrhea cases at New Bolton are worked up by Dr. Nolen-Walston, who claims she is only able to isolate a particular pathogen in around half of the cases she encounters. “The most accurate testing,” Heidmann asserts, “is DNA testing utilizing PCR” (polymerase chain reaction testing). Even yet, there are a significant percentage of false negatives. It is upsetting for both customers and veterinarians since, in certain cases, determining the cause can assist steer treatment.

“It’s academically interesting for the veterinarian and emotionally fulfilling for the customer to know what the risk factors are for their horse in the future,” he continues, “but on a practical level, we treat diarrhea pretty much the same way regardless of the organism that could be there.” In some circumstances, however, the importance of diagnosis cannot be overstated.

“It may be necessary to rule out infectious causes in some cases.” Additionally, some causes, such as PHF, necessitate the administration of a specific medication that, if not administered, is far more likely to end in death.” Veterinarians can employ a variety of tests to detect the source of diarrhea in horses, depending on the clinical indications they observe:

  • The presence of infectious agents such as coronavirus, Salmonella, C. difficile, C. perfringens, andN. risticii, as well as R. equi and rotavirus in foals, may be determined from fecal samples. Blood tests indicate the amount of water in the body, as well as the electrolyte balance, blood proteins, and pH. Ultrasound can reveal thicker intestines, pinpoint particular parts of the diseased bowel, and detect abscesses, swollen lymph nodes, and extra or contaminated fluids around the intestines
  • However, it is not always effective. The results of a biopsy or an abdominocentesis (collecting abdominal fluid with a hollow needle for testing) might indicate abnormal cells or germs.

As a precaution, if the source of your horse’s diarrhea is infectious, Heidmann suggests isolating him and implementing biosecurity precautions for at least two weeks after the infection has resolved. Because both coronavirus and Salmonella are shed in feces, Nolen-Walston recommends using stall-cleaning instruments designed specifically for this purpose and disposing of manure without spreading it on fields.

Also, be certain that stall mucking is done with boots, gloves, and either a change of clothes or coveralls on the part of the caretaker.

Treatment Plans

Nolen-most Walston’s effective diarrhea therapy consists of three steps:

  1. Determine the causative agent and treat it accordingly. The majority of diarrhea patients require supportive care in addition to the diagnosis-specific therapies. Ensure that you are getting enough water
  2. Treatendotoxemia. When Gram-negative bacillus (rod-shaped) bacteria die, the cell walls of the bacterium become extremely poisonous to horses.

When a healthy horse’s stomach is functioning properly, there is generally enough endotoxin to kill 100 horses, but the gut has extremely tight connections, which prevent germs from leaking out, according to Nolen-Walston. The gut, on the other hand, gets inflamed when there is diarrhea, and connections can leak endotoxin into the bloodstream. In addition, “horses with endotoxemia have gums that range in color from bright pink to dark red or purple, with a purple line around their teeth, which is known as a toxic line,” she explains.

” They are treated with flunixin and other anti-endotoxic drugs in order to minimize the inflammation that is the cause of the organ damage caused by endotoxemia.” It is believed that endotoxin is responsible for the fever, rapid heart rate, and uncontrolled inflammation that affects various organ systems throughout the horse’s body.

“Although endotoxins do not directly cause laminitis, horses suffering from severe diarrhea and endotoxemia are more likely to develop organ failure, which begins in the feet.” “Laminitis is certainly the most prevalent cause that an equine colitis patient does not survive,” says the veterinarian.

According to Nolen-Walston, “We can also administer plasma from horses who have been vaccinated against endotoxin so that their antibodies will bind to and deactivate it,” she adds.

It “binds” the toxins and also binds the water, so the horse loses fewer fluids during the diarrheal episode, according to Heidmann’s findings.

Restoring Normal Gut Flora

“The stomach of a healthy horse generally contains enough endotoxin to kill 100 horses, but the gut’s tight connections prevent germs from leaking out,” Nolen-Walston explains. The colon becomes inflamed when someone has diarrhea, and connections can leak endotoxin into the bloodstream.” In addition, “horses with endotoxemia have gums that range in color from bright pink to dark red or purple, with a purple line around their teeth, which is known as a poisonous line,” says the author. ‘The white blood cell levels in these animals are quite low.’ In order to minimize the inflammation that contributes to endotoxemia’s organ damage, flunixin and other anti-endotoxic medicines are used.

In addition to low blood pressure and hemorrhages, these horses can suffer from liver malfunction, renal necrosis (tissue death), and shock, according to the veterinarian.

Treatment for endotoxemia can also be accomplished by administering endotoxin-binding medications (polymyxin B).

It is also possible to absorb toxins using charcoal or bentonite clay in powdered form (smectite clay; di-tri-octahedral smectite, commonly known as Bio-Sponge), which is administered through an endoscopy.

It “binds” the toxins and also binds the water, so the horse loses fewer fluids during the diarrheal episode, according to Heidmann, the manufacturer.


As disgusting as it may seem, fecal transfaunation has been shown to be useful in the treatment of various diarrhea patients, including C. difficile. According to Heidmann, “it is the process of collecting healthy horse dung, sifting it, and then delivering the substance to a sick horse.” “It’s not uncommon to observe foals consuming their moms’ feces. It’s an innate tendency for them to get the beneficial bacteria into their stomachs. We only perform this in the sickest patients, but it has been shown in certain circumstances to be connected with a reduction in clinical symptoms.”

Take-Away Message

Although this is not an exhaustive list, now that you are aware of the most frequent indications, causes, and treatments for diarrhea in horses, you will be able to better correctly determine the severity of your horse’s condition. However, it is always better to err on the side of caution. In Nolen-opinion, Walston’s “one of the most common mistakes rookie horse owners make is not treating diarrhea as seriously as they should.” “It has a considerably higher chance of becoming lethal in horses than it does in people.”

Diarrhea in Your Horse Can Be a Sign of a Serious Problem

It is possible that your horse’s health is being compromised if he is experiencing diarrhea or has overly loose feces. If the condition does not resolve within a day or so, you should consult with your veterinarian about it. When a horse has diarrhea, it can get dehydrated very rapidly, and dehydration can lead to colic, which is a potentially life-threatening gastrointestinal ailment. You may not be aware that the underlying cause of your horse’s diarrhea is a major health concern that is tough to diagnose on your own.

Why Do Horses Get Diarrhea?

It is important to note that diarrhoea is a symptom rather than a disease in and of itself, and it frequently suggests that something is wrong with a horse’s digestive tract. Horse dung is often a pile of strongly formed, circular “buns” or “road apples” that have been piled together. It is possible for the horse’s digestive system to be changed in some way, leading in aberrant motility and fluid absorption, resulting in dung that is mildly runny to extremely loose and watery in consistency. In severe circumstances, the loose manure may be forced out of the stall and end up coating the walls of the stall and everything else that gets in its way.

However, it can be exceedingly acute and severe in some situations, or it might become chronic and need continuous therapy and attention in others.

While the majority of incidents are not a major concern, diarrhea can be a sign of a more serious, perhaps life-threatening condition.

During extreme cases, the loose manure may be forced out of the stall and end up coating the walls of the stall and anything else that gets in the way. Sometimes diarrhea can persist a day or two and then go away on its own, and you will never be able to pinpoint the cause. Some instances are quite acute and severe, whilst others are chronic in nature, need continuous therapy and care. Diarrhea in horses is caused by a variety of factors. While the majority of incidents are not a major concern, diarrhea can be a sign of a more serious, perhaps life-threatening medical condition. In horses, diarrhea can be caused by a variety of factors, some of which are as follows:

You should investigate what else might be causing the diarrhea if it is not caused by anything clear that you know will pass (such as a small behavioral factor).

If your horse exhibits any of the following signs in addition to having watery manure, you should be concerned:

  • In the dung, there may be blood or mucous. Manure with a foul odor (in addition to the usual manure odor)
  • More than 24 hours of diarrhea is considered to be severe. “Projectile pooping” is a term used to describe the act of pooping into a projectile. Other signs and symptoms of colic
  • Increased warmth in the rectal cavity
  • Lethargy
  • Before the diarrhea started, there were signs of weight loss or other health concerns
  • Signs of dehydration (do a skin pinch test or a capillary refill test to determine this)
  • Gums that are pale in color
  • A lack of desire to eat


If your horse is suffering from diarrhea, you must first establish the severity of the problem. You may already be aware that your horse is scared when the farrier comes, when riding in the trailer, and when competing at horse shows. Running manure in these situations is unlikely to be an indication of disease, and things will return to normal after the stress has passed. Make certain that your horse is eating and drinking regularly if this is not the case. If the diarrhea has not subsided after 24 hours, contact your veterinarian, who will assist you in determining what is causing the diarrhea and putting your horse on the right medicine.

The horse’s veterinarian may also administer medicines to alleviate any gastrointestinal discomfort and to aid in the slowing of the horse’s digestion.

Antibiotics or other drugs may be prescribed for your horse, depending on what is causing the diarrhea in the first place.

Although it is difficult to completely avoid it, smart preventative actions may be taken, such as:

  • Avoid making frequent modifications to your feeds. Introduce horses to lush pastures in small increments. Store grains and concentrated food in a secure location so that horses that could escape are unable to assist themselves. Vaccinate your horse with the essential vaccinations as well as any additional vaccines that are recommended for your area.

If you have any reason to believe your pet is unwell, contact your veterinarian immediately. Always consult your veterinarian for health-related inquiries, since they have evaluated your pet and are familiar with the pet’s medical history, and they can provide the most appropriate suggestions for your pet.

How to Stop Diarrhea in a Horse

As a horse owner, checking the quality and consistency of your horse’s droppings becomes second nature to you as a matter of course. His fecal output is a good indicator of his intestinal health. Diarrhea is frequently caused by changes in hay or feed. A day of light diarrhea is not reason for alarm if food modifications have occurred; nevertheless, severe diarrhea or diarrhea caused by unknown causes need immediate veterinarian intervention. Identifying the source of diarrhea is essential to preventing it from recurring.

Equine Diarrhea Causes

It becomes second nature to you as a horse owner to check on the regularity and quality of your horse’s droppings. Intestinal health is indicated by the amount of fecal output produced. Changes in hay or feed are frequently the cause of diarrhea. When feeding modifications have occurred, a day of small loose bowels is not a cause for alarm; nevertheless, severe diarrhea or diarrhea caused by unknown causes requires immediate veterinarian intervention. Identifying the source of diarrhea is essential to stopping it.

Diarrheal Diagnosis

If your horse is suffering from diarrhea, your veterinarian can determine the source of the problem using a fecal culture and a rectal examination. She will collect blood samples in order to do a full blood count and serum chemical analysis. In the case of severe or chronic diarrhea, your horse may need to have belly X-rays or ultrasounds performed on him.

Abdominocentesis, often known as a belly tap, is a procedure that involves taking a fluid sample from the abdomen using a needle or catheter to help in the diagnosis of a medical condition.

Deworming Protocol

Comprehensive deworming may be necessary for horses suffering from chronic diarrhea. Consult your veterinarian about whether he should be treated with moxidectin or a “power pack” of fenbendazole for five days, regardless of whether he is current on his deworming regimen. Following that, ivermectin should be administered, as well as praziquantel to eliminate tapeworms from his system.

Medications and Supplements

Inquire with your veterinarian about whether a daily dewormer would be beneficial for your horse and whether it would help to halt the diarrhea. Probiotics and prebiotics can also be given to your horse in order to promote the growth of healthy intestinal flora in your horse’s digestive tract. Symptoms can be alleviated by using equine equivalents of kaopectate or bismuth. Certain digestive enzymes intended for equines may be beneficial in the treatment of diarrhea. Do not provide any of these drugs or supplements without first obtaining veterinarian approval, and do not administer them all at the same time.

Management Changes

If your horse has persistent, moderate diarrhea, simple management modifications, combined with treatment, may help to firm up his stools and make him more comfortable. If you reside in a sandy environment, you should supplement your dog’s diet with psyllium, which helps him move sand through his intestines more easily. Feed hay on a manger, on a mat, or in a tub, rather than directly on the floor. Turn your horse out as much as possible – ideally, all day, every day with shelter. Ascertain that he has constant access to fresh, clean water.

Ensure that your horse follows the deworming regimen prescribed by your veterinarian.

Severe Diarrhea

A combination of management modifications and therapy may be necessary if your horse suffers from chronic, moderate diarrhea. When living in a sandy environment, you should supplement your dog’s diet with psyllium, which helps him move sand through his intestines more easily. If possible, keep hay off the ground by placing it in a manger, mat, or tub. Provide as much time for your horse to be outside as possible; preferably 24 hours a day with shelter. Provide him with access to fresh, clean water at all times.

First aid: dealing with diarrhoea

  • It is determined by the quantity of water in a horse’s droppings how loose the droppings are, and minor bouts of diarrhoea are normally nothing to be concerned about. Whenever a horse gets disturbed or anxious, such incidents are common – for example, when the horse is being prepared to go to a show. Diarrhoea in an adult horse is unlikely to constitute an emergency if the horse is bright, healthy, and eating and drinking. However, if the diarrhoea persists for more than 48 hours, your veterinarian should be informed immediately. However, if an adult horse with diarrhoea becomes unwell – particularly if it exhibits indications of colic or laminitis, or if it develops a high temperature – you should seek medical attention promptly from your veterinarian. Any sort of diarrhoea in a foal should be reported to your veterinarian as soon as possible. The signs and symptoms to watch for If diarrhoea comes suddenly and is accompanied by the production of large quantities of loose droppings on a regular basis, a significant amount of fluid can be lost from the body very rapidly. Due to copious diarrhea, a horse can fast become dehydrated and lose more than 40 litres (10 gallon) of water and electrolytes in the course of a single day, if not more. As a result of such fast dehydration, a horse can get extremely unwell, with potentially deadly symptoms ranging from laminitis to renal failure. Because it produces significant gut inflammation as well as immediate pain and anguish, such acute diarrhoea is correctly referred to as ‘enterocolitis.’ Keep an eye out for indicators of dehydration, which include the following:
  • The skin tenting phenomenon occurs when you squeeze the skin and it does not return to its natural position, but instead remains pinched. Eyes that have sunk in
  • Mucus membranes that are dry and sticky
  • Urine production has been reduced.

If you have any of these symptoms, you may be very dehydrated. Maintain adequate fluids for the sick horse and urge it to drink, as well as contacting your veterinarian. It may be necessary to provide fluids and electrolytes through a stomach tube if your horse is severely dehydrated. If the situation is serious, an intravenous drip may be required. It is common for a sick horse with severe diarrhoea to require 50-80 liters of IV fluids each day, which necessitates the need for specialized nursing in an equine hospital.

What you should do in this situation If you have an adult horse that is suffering from diarrhoea, you should do the following:

  • Place the horse in a stable. In case it is infectious, keep it away from other animals to avoid spreading the disease. Good hay should be fed, but not lush grass, as this may worsen the condition
  • Lots of water should be provided. Avoid feeding concentrates and explore the use of probiotics to support the formation of healthy gut flora in order to prevent disease. Additionally, provide different buckets of electrolyte-infused water in addition to ordinary water
  • The horse’s temperature should be checked. Consult your veterinarian if it is elevated and the horse looks to be dehydrated and unwell. Look for signs of oedema (fluid buildup) under the abdominal button and on the lower limbs. Oedema can occur in severe diarrhoea episodes due to a decrease in blood protein levels, which can be fatal. In the event that you detect this symptom, you should contact your veterinarian immediately. Make sure you are following your worming regimen, since diarrhoea may be caused by parasites, and appropriate worm management will lessen the likelihood of issues. There is always a possibility that diarrhoea will spread to other horses or persons in the vicinity. As a result, it is important to practice extreme caution when it comes to personal hygiene and to confine the infected horse to a confined area away from all other animals. To prevent skin injury on the horse’s dock and buttocks, clean them thoroughly and apply petroleum jelly to them. Keep the tail clean by wrapping it in bandages.

What is the source of diarrhoea? There are numerous and diverse causes of horse diarrhoea. When a horse is ailing, a veterinarian may be unable to determine the cause of the problem solely by doing a clinical examination; samples are frequently obtained for diagnostic testing. It can be difficult to determine a specific reason, and it may be necessary to do many testing. The following are examples of potentially dangerous causes of diarrhoea:

  • The presence of infections, such as salmonella, that can be transmitted to other horses and people
  • Intestinal worms, particularly cyathostomes, are a common occurrence. Diversion of feed due to unexpected availability to lush grass or overfeeding concentrates
  • Dietary disturbance following a change in feed source
  • It is recommended to avoid the use of antibiotics, which can disturb typical healthy flora in the intestine and cause diarrhoea
  • Intestine tumors that grow inside the colon and interfere with normal gut function
  • Sand colic is a condition in which hungry horses on inadequate pasture consume sand, which destroys their intestines. For example, liver disease or heart failure are examples of internal organ dysfunction. When the body’s fat metabolism is disrupted, this is known as hyperlipaemia, and it is most typically found in ponies and donkeys. The term “peritonitis” refers to an inflammation of the digestive tract. Inflammatory response to some drugs, such as “bute”

Diarrhea in horses: The causes, treatments, and complications

Originally published in HORSE magazine (November 2004), this first aid piece is a follow-up to the original.


The bacteria that cause diarrhea are the most frequent pathogens – Salmonella and Clostridium difficile are two of the most commonly seen. Antibiotic usage has been linked to the development of Clostridium difficile in both humans and horses. While antibiotics are useful in killing bad bacteria, they can also kill good bacteria at the same time, upsetting the balance of flora in the body, according to internal medicine specialist Dr Peter Heidmann of the Palm Beach Equine Clinic in Wellington, Florida.

  1. It is possible that when a horse is put on antibiotics for whatever reason, such as a wound or an illness, that the beneficial bacteria in the intestines would be perturbed, allowing harmful bacteria, such as Clostridium difficile, to flourish.
  2. There are many different forms of salmonella, with the majority of them being suited to birds or cattle or other animals.
  3. Horses can also have salmonella and show no signs of illness, allowing them to spread the disease to one another.
  4. The bacteria that cause diarrhea are the most frequent pathogens – Salmonella and Clostridium difficile are two of the most common types.
  5. loading=”lazy” Salamonella and Clostridium difficile are among the most frequent bacteria that cause diarrhea.

  • Potomac Horse Fever is caused by a bacterium known as Neorickettsia risticii, which is carried by snails and transmitted by flies such as caddisflies.
  • The bacterium in caddisflies is picked up from streams during the warm weather months, and horses who come into contact with the flies or larvae may contract the illness and die.
  • Coronavirus is a virus that frequently causes diarrhea in humans.
  • The horse’s body must reline the intestine, and it does so fast, but it will take three to five days, during which time the horse may experience severe diarrhea as well as secondary illnesses.
  • Supportive care is the single most critical treatment for diarrhea, regardless of the underlying reason.

The organism itself, in contrast to bacterial infections, cannot be treated since there are no relevant medications available to treat coronavirus in horses.” On top of the viral causes of diarrhea, there are also mechanical factors to consider, such as the intake of loose sand, which can be a problem in particular areas.

Sand, in general, is irritating to the point that the body is unable to retain the fluid that it requires in the intestines.

When the sand is removed, the condition is typically resolved, and the gut is then able to re-establish a healthy lining.

Although toxic plants such as Oleander can be lethal if consumed in big quantities, little amounts of the plant can cause significant gastrointestinal irritation when consumed.

Difficulties with diarrhea have also been reported in horses exposed to other environmental pollutants, such as phosphate or pesticides.


Supportive care is the single most critical treatment for diarrhea, regardless of the underlying reason. Supportive treatment involves the administration of intravenous fluids to replace fluids lost, the administration of protein in the form of plasma to replace protein lost owing to lack of absorption, and the administration of electrolytes to maintain electrolyte balance. The next most critical step is to take steps to either re-establish healthy gut flora or to eliminate harmful bacteria from the body.

  1. In the early 2000s, the business Platinum Performance introduced a gastrointestinal health supplement called BioSponge® to the market.
  2. Toxins and water are bound together by the purified clay powder, which means the horse loses less fluid in their diarrhea as a result of the product’s binding properties.
  3. “While the efficiency of probiotics is quite varied, there are specific bacteria that are known to be connected with gut health,” Heidmann explains.
  4. The yeast used in old-fashioned breweries is also a species of Saccharomyces, but it is Saccharomyces cerevisiae, which is a distinct strain.

  • Jump to the Media In order to re-establish good flora, Heidmann recommends transfaunation, which involves collecting excrement from a healthy horse and purifying it before injecting it into a sick horse through tubing.
  • It replaces the beneficial ‘bugs’ that the horse is losing as a result of the diarrhea.
  • It is an innate tendency for them to get the beneficial bacteria into their stomachs.” We only do this in the most serious of circumstances, though.
  • “If we have salmonella or any other intestinal illness in people or dogs, we nearly usually put them on antibiotics,” he adds.
  • “There are a couple of exceptions to this rule.” Clostridium difficile is susceptible to antibiotics, with metronidazole being the most commonly used.
  • During the illness of the horse, and for a minimum of two full weeks after the infection has been clinically cleared, Heidmann suggests total isolation of the horse from other horses.
  • Molecular and DNA testing may be performed to ensure that the horse is free of illness, but he cautions that the testing process can be time-consuming and difficult.
  • According to the veterinarian, “there are occasions when the horse is shedding bugs but the tests do not pick it up.” Even though the most up-to-date standard of care is a DNA test known as PCR, it is still necessary to do many tests in order to obtain a positive result and a diagnosis.

“However, the safest course of action is to continue testing until you are confident.”


Heidmann warns of frequent consequences that might occur in severe diarrhea episodes, with laminitis being the most serious of them. When dealing with the sickest of horses, it is sadly not unusual for the veterinarian to successfully repair the intestines over a period of three to five days, only to discover that the feet have become extremely swollen as a result of toxins in the circulation. Whenever a horse’s intestine is damaged, the beneficial and harmful bacteria that are intended to be confined in the gut are able to ‘leak’ out into the bloodstream and become free in the abdominal cavity.

Another potentially life-threatening consequence is blood clotting.

It is possible that the horse could have trouble clotting or that they will become more susceptible to aberrant increases in clotting.

It can occur anywhere, but it most frequently occurs in the gut itself, where it is typically deadly.

Occasionally, the veterinarian will additionally administer anticoagulant drugs to the patient.

“The most telling symptom of a problem is its persistence,” Heidmann argues.

Fieber and tiredness are both immediate warning signals of a possible infection.

Most serious are those that have been burning for a day or two,” says the author.
