For more comprehensive strategies to prevent this, PetMD discusses how maintaining clean stables and paddocks can reduce the occurrence.

Understanding the Nature of Horses

Knowing the innate characteristics of horses provides the initial step towards comprehending coprophagy. Spend some time analyzing the basic, yet vital, components that symbolize a horse’s nature.

  1. Selective grazing: Horses, being natural foragers, spend a significant portion of their day grazing. This behavior makes them selective feeders, focusing mainly on grasses while avoiding the less desirable or potentially toxic plants. An example, horses might munch on lucerne or Timothy grass, yet ignore ragwort or bracken.
  2. Herd-oriented animals: Horses are herd-oriented creatures. They live in groups and establish a hierarchical system within their herd. This social order impacts their behavior, with younger or lower-ranking members mimicking the actions of the dominant ones. For example, if one horse begins to display coprophagy, there’s a chance others in the herd may copy their leader’s behavior.
  3. Curious nibblers: Horses exhibit an unusual but inherent trait of being curious nibblers. They frequently use their mouths to investigate their environment. Anything new or different noticed, such as a pile of fresh dung, could pique a horse’s curiosity enough to provoke a taste test.
  4. Digestive system’s design: Remarkably, horses’ digestive systems can extract a second round of nutrients from their waste. They have a unique digestive system, unlike humans or carnivores, enabling them to extract essential nutrients even from feces, given their high fiber content.
  5. Coping mechanism: Studies suggest that horses often resort to coprophagy under stress or lack of adequate nutrition. For instance, a horse confined in a stall without sufficient hay may try to satiate its appetite by eating its droppings.

Through understanding these inherent characteristics of horses, their seemingly odd behavior of eating poop begins to make sense. It’s a direct outcome of their selective grazing habits, herd dynamics, curiosity, digestive system, and coping mechanisms. The next section explores these reasons in more detail to further explain this peculiar horse behavior.

Investigating the Phenomenon: Why Would a Horse Eat Poop?

Investigating the Phenomenon: Why Would a Horse Eat Poop?

Several factors contribute to the phenomenon of a horse consuming feces. Often, it might be due to a nutritional deficiency, particularly a possible lack of fiber. Equines, being natural grazers, require a high-fiber diet for optimal gut health. Reduced intake of roughage like hay or grass may prompt them to satisfy this need through coprophagy. Just as a golfer needs proper equipment and nutrition to perform well in golf, horses require a balanced diet to maintain their health and prevent undesirable behaviors.

Additionally, boredom and limited social interaction can trigger this behavior. Horses, known for their herd instinct, thrive in social interactions and constant engagement with their surroundings. When confined to a solitary environment with minimal stimuli, they might develop unusual habits out of boredom, much like a person confined indoors might start playing basketball to pass the time.

Further, gut discomfort can also precipitate this act. Equines boast a delicate and complex digestive system and any gastrointestinal distress could lead them to eat poop. Parasitic infestations also drive horses towards feces consumption, given these parasites often reside within feces. Proper hats and coats can help protect horses from external parasites during outdoor activities.

Your horse may also indulge in this behavior out of curiosity or mirroring action. Young foals are particularly prone to it as they try to comprehend their environment, sometimes copying their mothers or herd mates. What they derive from this act is a dose of microorganisms essential for a healthy gut, particularly crucial during the foal’s early days. Whether preparing for camping trips or tending to the stables, understanding this behavior is essential for maintaining equine health.

Finally, coprophagy could be a reflection of your horse coping with stress. Changes in their living conditions, sudden weaning, or transition to a new feed could emotionally strain the horse, leading to this unusual response.

More often than not, a horse’s feces-eating behavior can be managed effectively by addressing the underlying triggers promptly. Ensuring a nutritionally rich diet, providing ample social interaction, maintaining gastrointestinal health, and minimizing stress can potentially dissuade your horse from engaging in coprophagy.

Health Implications of Horses Eating Poop

Health Implications of Horses Eating Poop

Addressing coprophagy promptly in horses isn’t just a matter of curbing an unpleasant habit, it’s vital for the animal’s health. Eating poop in horses bears implications that range from minor discomfort to serious health issues. Ultimately, the impact on health depends on the underlying cause of this behavior.

Nutritional deficiencies, one of the primary triggers of coprophagy, can lead to a host of issues. For instance, a vitamin or mineral imbalance, potentially due to insufficient or improper diet, can result in weakened immune systems, poor growth, skin problems, and even neurological issues in severe cases.

Horses partaking in poop eating due to social isolation or boredom may exhibit signs of anxiety. Anxiety itself can cause gastrointestinal problems such as ulcers, potentially escalating already tenuous health conditions.

Furthermore, a horse indulging in feces consumption because of gut discomfort might have its condition worsened. The presence of harmful bacteria or parasites in the poop can exacerbate gastrointestinal distress, ultimately leading to conditions like colic or even laminitis.

Parasitic infestations, another cause of this eccentric behavior, pose direct health dangers. A horse feeding on the feces of an infected horse can become a new host for the parasite, curtailing the animal’s overall wellbeing.

While the action of a horse eating poop isn’t typically life-threatening, certain conditions such as intestinal blockages and infectious diseases can take a serious toll if left unchecked. Understanding the roots and implications of this behavior is essential for owners to provide horses with optimal care. It’s important to consult with a veterinarian if your horse exhibits coprophagy, ensuring its health isn’t at risk.

Mitigating the Situation: How to Prevent Horses from Eating Poop

To effectively mitigate the situation and dissuade your horse from eating feces, there are several methods you can employ.

First, ensure a balanced diet for your horse. This involves providing high-quality hay, adequate minerals, and vitamins. A horse with nutritional deficiencies often resorts to eating feces. You might think about investing in commercial horse feeds that offer a complete and balanced ration. Make sure that your horse always has access to freshwater.

Second, address any social isolation or boredom the horse may experience. Horses are social animals and isolation can lead to stress and abnormal behavior, including eating feces. Inclusion in a group setting or herd can often alleviate this issue. Providing stalls with visual access to other horses or pastures with other horses can help resolve this. Remember to keep your horses intellectually engaged by offering toys, rotating pastures, or training routines.

Third, proper parasite control should be enforced. Fecal tests can identify any existing parasitic infestations. Deworming is usually prescribed if parasites are detected. This can prevent your horse from consuming feces that might contain parasite eggs.

Fourth, maintain a clean environment for your horse. Prompt removal of manure from stalls and pastures will lessen the opportunity for coprophagy.

Lastly, consult with your horse’s veterinarian. They might recommend dietary changes, or in some cases, administer medication if a physical discomfort is causing your horse’s coprophagy. Monitor your horse daily for any abnormal behavior and seek prompt veterinary assistance if needed.

By addressing underlying issues associated with your horse’s coprophagy and maintaining a proactive approach, you can prevent this behavior and ensure the well-being of your horse. These strategies can also contribute to long-term equine health.

Remember, it’s essential to recognize the signs, understand the triggers, and implement preventive measures to keep your horse healthy and prevent them from eating feces.

Cases of horses consuming feces indicate it’s no rare behavior. Numerous incidents involve horses of different breeds, ages, and backgrounds. Let’s explore two such instances.

  1. Four-Year-Old Quarter Horse: This horse, known for its docile nature, started displaying coprophagy after being shifted to a smaller pasture with a fewer companions. Despite receiving sufficient food and water, it began eating fecal matter, indicating possible social isolation or boredom. Addressing the social factors (more outdoor time, interaction with other horses) ultimately resolved the behavior.
  2. Older Draft Mare: This draft horse presented an interesting case. Already past her prime years and suffering from arthritis, she indulged in coprophagy in her paddock. Despite a balanced diet catered according to her age and condition, the mare exhibited this behavior. A vet check-up revealed the presence of internal parasites. After initiating a targeted parasite control program, her coprophagy subsided.

These case studies highlight that horses eat poop due to a range of reasons, which often extends beyond dietary needs. Remember, understanding the underlying causes enables prompt behavioral rectification, thus safeguarding your horse’s health.


So you’ve seen that horses eating poop isn’t as bizarre as it first seems. It’s a behavior driven by various factors – be it nutritional needs, social isolation, boredom, or even internal parasites. It’s crucial to remember that understanding the root cause is key to addressing this issue effectively. So next time you see a horse engaging in coprophagy, you’ll know it’s not just about diet. It’s a call for help, signaling that something might be off. Be it a change in diet, a need for companionship, or a vet checkup for parasites, your prompt response can help maintain your horse’s health. After all, prevention is better than cure, especially when it comes to the well-being of your equine friend.
