Mange in Horses

Causes of Mange

Mange is caused by very small mites on the skin of horses. The insects may either live on the surface or a short way underneath the surface of the skin. Not all mites are the same. The kind of mite on the horse’s skin is related to the affects. The mites that cause the condition are known as:

• Chorioptic mites affect the feet, legs and knees of horses. Mange however is most often observed below knee level. There is some evidence that these mites are more common in large draft horses.

• Psoroptic mites affect the skin near the hairy regions such as the tail and mane. This can obviously lead to hair loss which is why horses with these mites are probably the most unsightly of all. Horses in the U.S. however are believed to be exempt from this type of mange because it has already been eradicated in the country.

• Demodectic mites primarily affect the head region. Mange of this type is considered rare and resistant to treatment.

• Sarcoptic mites are responsible for the most contagious version of mange. The mites can affect nearly every part of the horse’s body and can even promote the occurrence of a secondary infection.

Symptoms of Mange

The most obvious symptom of the condition is intense itchiness. The skin on the affected areas will become red and will form scabs, cracks, crusts and oozing sections. Hair loss may also follow especially if the mites congregate near the head region.

Because of the irritation caused by these mites, horses will attempt to get rid of them. They may bite their skin or kick themselves near the affected region. This can complicate the condition. The skin may be injured further by the horse’s actions, leaving planet of openings for invading bacteria.

Treatment of Mange

Isolation is always part of mange treatment. This is because the mites can easily transfer from one horse to another. Aside from isolating the horse itself, all other tools and equipment that have been in contact with an mangy horse should be kept away from other horses. This includes grooming kits and tools.

There are a number of different products available that claim to be able to treat mange. If you are unfamiliar with any of the available products, consult a veterinarian first. Treatment often comes in the form of topical chemical applications that have to be administered in regular intervals. Skin that comes loose because of mange may have to be manually taken off.

Prevention of Mange

Like other pests, it isn’t always possible to completely eliminate mites. Regular grooming however and prompt isolation are top keys to preventing the spread of the condition to other horses. Ask your vet too about horse shampoos and grooming products that may discourage mite infestations.
