Mud fever, also known as pastern dermatitis, is a common skin condition affecting horses, particularly during wet and muddy conditions. It is caused by bacteria that thrive in damp environments, leading to painful sores and irritation on the lower legs. If left untreated, it can cause significant discomfort and lameness in affected horses.
Causes of Mud Fever
Mud fever is primarily caused by prolonged exposure to wet and muddy conditions, which soften the skin and make it more vulnerable to bacterial infection. The main culprit is Dermatophilus congolensis, a bacterium that thrives in damp environments. Other contributing factors include:
Constant wetting and drying of the skin
Trauma or cuts on the pasterns, allowing bacteria to enter
Poor stable management and hygiene
Weakened immune system
Recognising the Symptoms
Early detection is key to managing mud fever effectively. Look out for the following signs:
Redness and inflammation of the skin on the lower legs
Crusty scabs and oozing lesions
Matted hair around affected areas
Swelling and tenderness
Lameness in severe cases
Treatment and Management
If your horse develops mud fever, early intervention is crucial. Here’s how you can manage and treat it:
Clean the Affected Area – Gently wash the leg with an antibacterial solution and pat dry.
Remove Scabs Carefully – Softening the scabs with warm water and mild antiseptic can help remove them without causing further irritation.
Apply a Topical Treatment – Use antibacterial and soothing creams to promote healing and prevent further infection.
Keep the Area Dry – Avoid prolonged exposure to wet and muddy conditions.
Monitor for Improvement – Regularly check for any worsening of symptoms and consult a vet if necessary.
Preventing Mud Fever
Prevention is always better than cure. Here are some effective ways to reduce the risk of mud fever:
Improve Drainage in Paddocks – Ensure fields have good drainage to minimise mud accumulation.
Use Protective Boots or Bandages – These can help protect the lower legs from excessive moisture and mud.
Regular Grooming – Keep your horse’s legs clean and dry.
Stable Management – Provide dry bedding and a clean environment to reduce exposure to bacteria.
Boost Immunity – A healthy diet and regular vet check-ups can help keep your horse’s immune system strong.
Final Thoughts
Mud fever is a manageable condition with the right care and preventive measures. By maintaining good stable hygiene, monitoring your horse’s legs regularly, and taking proactive steps to prevent excessive moisture exposure, you can significantly reduce the risk of mud fever and keep your horse comfortable and healthy throughout the wetter months.
