If you’ve ever stood in your hay shed staring at a bale of clover hay, wondering if it’s safe for your horse, you’re not alone. Clover is a common legume found in pastures and hay fields, and it can be a nutritious option for horses. But it also comes with some unique risks that every owner should understand. Let’s break down everything you need to know about feeding clover hay to your horse, from its nutritional value to the potential pitfalls.
What Is Clover Hay and Why Do Horses Like It?
Clover hay is made from one of several clover species, most often red clover or white clover. It’s a legume, which means it’s higher in protein and calcium than grass hays like timothy or orchard grass. Horses tend to love the sweet taste of clover, making it a tempting choice for picky eaters. However, because it’s richer, you need to introduce it slowly and monitor your horse’s response. If you’re managing a horse that needs to limit its intake, a grazing muzzle can help control how much clover they consume in a pasture setting.
Nutritional Benefits of Clover Hay for Horses
Clover hay can be a valuable part of a balanced diet when fed correctly. It typically contains 12-20% crude protein, which is excellent for growing horses, lactating mares, or hard keepers. It also provides good levels of calcium and phosphorus, supporting strong bones and teeth. The high fiber content aids digestion, but because it’s more calorie-dense than grass hay, you’ll want to adjust grain rations accordingly. Always have your hay tested to know exactly what you’re feeding, especially if your horse has specific health needs.
Potential Risks of Feeding Clover Hay
While clover hay is generally safe, there are three main concerns: mold, slobbering, and photosensitization. Mold can develop in clover hay that’s baled too wet, leading to respiratory issues or colic. Slobbering, or excessive drooling, is caused by a fungus called Rhizoctonia leguminicola that produces slaframine. This isn’t toxic, but it can be messy and alarming. More seriously, some clover species can cause photosensitization, making your horse’s skin sensitive to sunlight and leading to sunburn on unpigmented areas. If you notice any of these signs, stop feeding the hay and consult your vet. Keeping a well-stocked horse first aid kit on hand is always a good idea for managing minor issues quickly.

How to Safely Introduce Clover Hay to Your Horse
Start by mixing a small amount of clover hay with your horse’s usual grass hay, gradually increasing the proportion over 7 to 10 days. Watch for any changes in behavior, manure consistency, or appetite. If your horse has a history of laminitis or metabolic issues, be extra cautious due to the higher sugar content in clover. Some horses are more sensitive than others, so individual monitoring is key. If you’re concerned about your horse’s weight or health, discuss the switch with your veterinarian before making changes.
Red clover hay can sometimes develop a black or dark brown mold that looks alarming but is often just a harmless saprophyte. However, any moldy hay should be avoided to prevent respiratory irritation. When in doubt, toss it out!
Signs of Clover Hay Problems to Watch For
Keep an eye out for excessive drooling, which can soak your horse’s hay and water. If you see this, remove the hay and offer fresh grass hay instead. Photosensitization appears as red, swollen, or peeling skin on white or pink areas of the face and legs. In severe cases, blisters may form. If your horse is out in the sun and you notice these symptoms, bring them into a shaded stall and call your vet. For daily care, using a gentle horse body brush can help you spot skin changes early during grooming sessions.
When to Avoid Clover Hay Altogether
Clover hay is not recommended for horses with certain conditions. If your horse has Cushing’s disease, equine metabolic syndrome, or a history of laminitis, the higher sugar and starch levels in clover can be risky. Pregnant mares should also be fed clover hay with caution, as some molds can cause pregnancy loss. For most healthy adult horses, though, clover hay can be a safe and nutritious option when sourced from a reputable grower and stored properly. Always inspect each bale for dust, mold, or off smells before feeding.
Feeding clover hay is a personal choice that depends on your horse’s individual needs. By understanding the risks and benefits, you can make a decision that supports your horse’s health and happiness.
