What Is Selenium?

Selenium is a trace mineral that is found not only in the soil, but also in some foods and in water.

This vital mineral helps to improve equine immunity and ensure that your horse has a healthy metabolism.

All horses need to have selenium in their diet, but since it is a micro mineral it is often difficult to ensure that they have enough selenium in the foods they eat. 

When your horse does not have enough selenium in their diet, it can negatively affect their growth and even cause additional health problems.

Signs of a Selenium Deficiency

It’s important to be aware of the signs and symptoms that your horse may have a selenium deficiency. This will allow you to address the issue right away and minimize any negative consequences.

Some of the most common signs that your horse is deficient and in need of selenium supplementation include muscle weakness, diarrhea, anorexia, and retained placenta.

Even if your horse isn’t showing physical problems, it doesn’t mean that they are not suffering from a selenium deficiency.

A lack of selenium can also express itself as an inability to resist and fight off disease, increased time for muscle recovery, and even poor fertility.

This means that you need to be aware of the health of your horse and be willing to act quickly if you suspect a selenium deficiency.

How Does Selenium Help to Keep Your Horse Healthy?

Selenium helps to improve the health of your horse in a number of ways.

Not only does it boost your horse’s ability to produce antibodies, which will increase their immune system, but it also helps your horse’s reproduction and growth.

Boosts in growth and reproduction will manifest themselves as improved overall daily health and better and healthier pregnancies.

When your horse has enough selenium in their diet, they will be able to help prevent damage to the membranes of their cells, as well as improved vitamin E retention in their bodies.

Together, vitamin E and selenium work to reduce the risk of your horse suffering from muscle problems, such as exertional rhabdomyolysis syndrome and white muscle disease.

With this in mind, supplementing selenium and vitamin E can have a tremendous positive impact on your horses overall health and performance.
