About Mud Fever

Mud Fever occurs mostly around the coronet, heels and pastern in horses but can also occur higher on the leg or belly.

Causes of Mud Fever

Mud Fever is caused by a bacterium known as dermatophilus congolensis which thrives in wet conditions and therefore the condition is more common during the winter months.

Symptoms of Mud Fever

The bacteria penetrates chapped, damaged or softened skin and the legs develop weepy sores which lead to scabs. In severe cases the leg may swell and the horse may develop lameness. Horses or ponies with heavy feather on the leg can be particularly prone to mud fever in extremely muddy conditions, as the hair becomes covered in wet mud and remains damp. Horses with white legs and pink skin are also more prone to Mud Fever.

Prevention of Mud Fever

Mud fever can be prevented by bringing the horse or pony in periodically to allow the legs to dry completely and brushing off all mud.

There are also a variety of barrier creams that can be applied to dry, clean legs to protect the skin to help prevent mud fever and leg wraps and bandages that can be worn in the field designed to help prevent Mud Fever.

Treatment of Mud Fever

To treat Mud Fever, clip the hair, clean the legs thoroughly and soften the scabs by applying a dilute antiseptic solution or wash the legs with an antibacterial shampoo. Gently remove the scabs, dry thoroughly and then treat the area with a Mud Fever product or by applying an antibiotic cream twice daily. In severe cases of Mud Fever where the leg has been swollen antibiotic treatment may be needed.

Once the Mud Fever has been treated the skin may remain tender and applying a soothing cream such as zinc or castor oil can ease this.
