Last Updated on May 22, 2022

As a horse owner or carer, it is important to know what your horse is eating when he is out grazing. But is clover bad for horses if you’ve got a lot of it?

You will find a range of different grasses and plants in your fields, and not all of them are good. Let’s find out everything you need to know about clover and horses!

Is Clover Good For Horses?

Clover can be found in many horse paddocks, as this plant is widespread in wild areas. It self-seeds easily and is also commonly included in horse pasture seed mixes.

A moderate amount of the right types of clover is beneficial to the grazing land and also the horses that eat it. Clover fixes nitrogen in the soil from the air, allowing other plants to access this essential nutrient. Clover is a high-quality forage material for horses, with high levels of protein.

Whilst many people assume that horses just eat grass and hay, they benefit greatly from grazing a mix of grasses and other plants. Clover can be a useful part of this mix, and it is recommended that horse pasture should consist of up to 20% clover.

Is Clover Good For Horses

There are many different types of clover available, but there are only two that are normally fed to horses: the common red and white clovers. These are the types that are widely naturalized around the world, found growing in wildflower meadows and on grass verges.

So, if your paddock contains around one-fifth of red and white clover, this is a sign that you have good grazing land. But this doesn’t mean we are in the clear when it comes to clover, as these plants can still cause problems in horses!

So, what happens if you have other types of clover or a lot of clover? Can red and white clover ever become a problem? Let’s find out!

Is Clover Bad For Horses?

When it comes to grazing horses on land with clover, there are two problems that can occur. One of these is relatively mild, but the other can be very serious. This means it is important to know about the clover on your land, so you can take the appropriate steps to keep your horse safe.

Why is clover bad for horses? Here are the two main reasons:

  • Clover And Slobbers In Horses

Horses grazing on red and white clover will occasionally develop a condition called slobbers. This is caused by a mold that grows on clover in cool wet conditions and often occurs in the fall. The mold can also occur in hay that contains dried clover.

When a horse has slobbers, it produces a huge amount of excessive saliva. This causes the horse to drool constantly, leading to the name ‘slobbers’.

Slobbers are not normally a life-threatening problem for the horse, but it is essential to ensure that the horse has an adequate supply of water to ensure they do not become dehydrated.

To reduce the risk of slobbers, do not allow your horse to access pasture land that is rich in clover during the fall months.

  • Alsike Clover Toxicity In Horses – Is Clover Bad For Horses

Whilst red and white clover are relatively safe for horses to eat, alsike clover can cause debilitating and life-threatening health problems. The toxin in alsike clover has not been identified, although it is thought that the problems may arise as a result of different types of mold.

When horses eat alsike clover, this can have serious detrimental effects that may not be reversible. There are two main conditions caused by alsike clover – photosensitization, and big liver syndrome.

Photosensitization causes the skin of the horse to become extremely sensitive to UV light, causing sunburn to happen with only small amounts of sunlight. These lesions can be very sore, especially if they become infected.

Big liver syndrome is more likely to occur with long-term exposure to alsike clover. The cells of the liver are gradually destroyed, causing it to lose vital functions. Liver failure is often fatal in horses, and the effects of long-term alsike clover toxicity can be irreversible.

Alsike clover can be recognized by its distinctive flowers, which are dark pink at the base and lighter at the top. If you find this type of clover on your land, you should seek advice from an agricultural specialist to find out how to eliminate it.

Summary – Is Clover Bad For Horses

So, as we have learned, if clover is bad for horses depends on the type of clover you have and how much of it is available. Clover benefits grazing land by fixing nitrogen in the soil and can be an important part of your horse’s diet. However, some types of clover can cause health problems in horses, so it is important to check what you have growing on your land.

Why Do Horses Drool After Eating Clover?
