What Food Can Make a Horse Sick? Unveiling the Dangers in Your Horse’s Diet

Certain foods, while seemingly harmless, can cause serious illness in horses; understanding these risks is vital for every horse owner. Many common plants and improperly stored feeds contain toxins that lead to sickness, and it is important for horse owners to know what food can make a horse sick and how to prevent it.

Introduction: A Horse’s Delicate Digestive System

Horses possess a highly sensitive digestive system. Unlike humans or many other animals, they cannot easily vomit to expel harmful substances. This makes them particularly vulnerable to food-related illnesses. A seemingly innocent snack could trigger colic, laminitis, or even be fatal. Knowledge of potentially toxic plants and feed management is essential for preventing illness in horses. Knowing what food can make a horse sick empowers horse owners to proactively protect their equine companions.

Common Toxic Plants for Horses

Many plants common in pastures and hay fields can be toxic to horses. Proper identification and removal are crucial.

Ragwort: Contains pyrrolizidine alkaloids, which cause irreversible liver damage.
Oleander: Extremely toxic; even small amounts can be fatal.
Yew: All parts of the yew tree are poisonous, causing sudden death.
Bracken Fern: Can lead to vitamin B1 deficiency.
Nightshade: Contains alkaloids that affect the nervous system.
Buttercups: While not highly toxic, can cause mouth and gastrointestinal irritation if ingested in large quantities.
Red Maple: Especially toxic when wilted, causing hemolytic anemia.

Careful pasture management, including regular weed control and fencing off dangerous areas, is vital. It is critical to know what food can make a horse sick if it is a plant growing in your pasture.

Feed Storage and Mold Contamination

Improperly stored feed can become contaminated with mold, leading to the production of mycotoxins. Mycotoxins are poisonous substances produced by fungi and can cause a variety of health problems in horses, including:

Neurological problems: Including head pressing, circling, and seizures.
Liver damage: Leading to jaundice and other liver-related symptoms.
Digestive upset: Colic, diarrhea, and decreased appetite.
Immune suppression: Increasing susceptibility to infections.

Ensure feed is stored in a dry, well-ventilated area. Regularly inspect feed for signs of mold, such as clumping, discoloration, or a musty odor. Discard any feed that appears to be contaminated. Prevention is key!

Grains and Carbohydrate Overload

While grains are a common component of many horse diets, overfeeding or sudden introduction of high-carbohydrate feeds can lead to serious health problems.

Laminitis: Inflammation of the laminae in the hoof, causing extreme pain and potentially permanent damage.
Colic: Abdominal pain, which can range from mild discomfort to life-threatening obstruction.
Equine Metabolic Syndrome (EMS): A hormonal disorder characterized by insulin resistance and increased risk of laminitis.

Carefully monitor your horse’s weight and adjust their diet accordingly. Introduce new feeds gradually. Choose feeds with low starch and sugar content, especially for horses prone to laminitis or EMS.

Prevention and Management

Preventing food-related illnesses in horses involves a multifaceted approach:

Pasture Management: Regularly inspect pastures for toxic plants and implement weed control measures. Ensure access to clean water.
Feed Storage: Store feed in a dry, well-ventilated area. Discard any feed that appears moldy or spoiled.
Diet Management: Introduce new feeds gradually. Choose feeds appropriate for your horse’s age, activity level, and health status. Consult with a veterinarian or equine nutritionist to develop a balanced diet.
Early Detection: Monitor your horse for signs of illness, such as decreased appetite, colic, diarrhea, lameness, or neurological abnormalities.
Veterinary Care: Seek immediate veterinary attention if you suspect your horse has ingested a toxic substance or is showing signs of illness.

By taking proactive steps to protect your horse from potentially harmful foods, you can significantly reduce the risk of illness and ensure their long-term health and well-being. Always remember that what food can make a horse sick needs constant vigilance to prevent.

Frequently Asked Questions (FAQs)

Can horses eat fruit?

Yes, horses can eat certain fruits in moderation. Apples and carrots are popular treats. However, it’s important to remove any pits or seeds, as these can be toxic. Also, avoid overfeeding fruit, as the high sugar content can contribute to weight gain and increase the risk of laminitis. Always offer fruit in small quantities as a treat, not as a staple part of their diet.

Is it safe to feed horses lawn clippings?

No, it is generally not safe to feed horses lawn clippings. Lawn clippings can ferment quickly, leading to colic. They may also contain toxic plants, pesticides, or fertilizers. It’s best to avoid feeding horses lawn clippings altogether.

What are the symptoms of ragwort poisoning in horses?

Symptoms of ragwort poisoning can be subtle at first and may include weight loss, jaundice (yellowing of the eyes and gums), photosensitivity (sensitivity to sunlight), and neurological signs. Unfortunately, liver damage caused by ragwort is often irreversible.

How can I prevent my horse from eating toxic plants in the pasture?

Regularly inspect your pasture for toxic plants and remove them by hand or with herbicides. Consider fencing off areas where toxic plants are prevalent. Providing adequate forage can also reduce the likelihood of horses grazing on undesirable plants.

What should I do if I suspect my horse has eaten something poisonous?

Contact your veterinarian immediately. Do not attempt to induce vomiting. Provide your veterinarian with as much information as possible about what your horse may have ingested. Time is of the essence in these situations.

Are supplements always safe for horses?

Not necessarily. Some supplements may contain ingredients that are harmful to horses, or they may interact with medications. Always consult with your veterinarian before giving your horse any supplements. Choose reputable brands and follow the recommended dosage guidelines.

Can horses eat bread?

Bread is generally safe for horses in very small quantities, such as one slice as a treat, and should never be moldy. However, it offers little nutritional value. It is not recommended as a regular part of their diet. The starches may contribute to weight gain.

What is colic, and how is it related to food?

Colic refers to abdominal pain in horses. It can be caused by a variety of factors, including diet, stress, and dehydration. Certain foods, such as moldy hay or sudden changes in feed, can increase the risk of colic.

Is it safe to feed horses treats from my garden?

It depends on what is in your garden. Only feed items confirmed safe and in very limited quantities. Some common garden plants are toxic to horses. Research before feeding.

What is the risk of feeding horses haylage?

Haylage carries a risk of botulism. This is a paralytic disease that can be fatal. If botulism is suspected, urgent veterinary intervention is needed. The best preventative measure is to avoid feeding haylage.

How important is the quality of hay for horses?

Hay quality is extremely important for horses. Moldy, dusty, or weed-infested hay can cause respiratory problems, colic, and other health issues. Choose high-quality hay that is free from mold and weeds.

Can horses have allergies to certain foods?

Yes, horses can develop allergies to certain foods. Common food allergens include alfalfa, wheat, and soy. Symptoms of food allergies can include skin problems (hives, itching), respiratory problems, and digestive upset. Work with your veterinarian to identify and manage food allergies.
