Your Mud Fever Questions Answered - Causes, Symptoms and Prevention

What is Mud Fever?

Mud fever primarily affects a horse’s lower legs, especially the pastern and fetlock areas. It presents as inflamed, scabby, or crusty skin, often accompanied by hair loss and oozing sores. In severe cases, swelling, heat, and pain can lead to lameness.

While the name implies a problem linked solely to mud, mud fever is actually a type of bacterial skin infection caused by Dermatophilus Congolensis, although fungal and other microbial infections can sometimes contribute. The bacteria thrive in damp, dirty environments and gain entry through skin cracks or abrasions.


Common Causes of Mud Fever

Several factors contribute to the onset of mud fever:

Wet and Muddy Conditions: Prolonged exposure to wet, muddy environments weakens the skin’s protective barrier.

Skin Damage: Scratches, nicks, or irritation caused by abrasive mud or vegetation can create entry points for bacteria.

Poor Hygiene: Unsanitary conditions in stables or fields can exacerbate the risk of infection.

Compromised Immune System: Horses with weakened immune systems may be more susceptible to infections.

Prolonged Bandaging: Keeping a horse’s legs bandaged for too long without airing them out can trap moisture and promote bacterial growth.

Excessive Washing: Over-washing the legs strips away natural oils, reducing the skin's ability to repel moisture.


Symptoms of Mud Fever

Recognizing the signs early can help prevent the condition from worsening:

  • Scabs or crusty lesions on the lower legs
  • Hair loss or matted hair around affected areas
  • Oozing or discharge from the skin
  • Swelling or heat in the affected limb
  • Sensitivity or pain when touched
  • Lameness in severe cases

Prevention Tips

Preventing mud fever involves a combination of good management practices and vigilant care:

Stable Management: Ensure stables are clean and dry. Remove manure and wet bedding regularly to reduce bacterial exposure.

Field Management: Rotate pastures and create dry-standing areas to minimise prolonged exposure to mud. Use gravel or mats in high-traffic zones.

Daily Checks: Inspect your horse's legs daily for signs of mud fever, especially in muddy weather.

Skin Protection: Apply waterproof barrier creams which are naturally antibacterial and antifungal to the pastern area before turnout.

Avoid Over washing: Only wash your horse's legs when necessary, and thoroughly dry them. Apply an antiseptic drying powder.

Boost Immune Health: A balanced diet and proper nutrition help maintain skin integrity and overall health.


Treatment for Mud Fever

If your horse develops mud fever:

Cleanse the Affected Area: Gently cleanse the area with a mild antiseptic solution like Quick-Silver Lotion Spray, avoiding scrubbing, as this can cause further irritation.

Dry Thoroughly: Pat the area dry and puff on some drying powder such as Flowers and Zinc Antiseptic Drying Powder to absorb any excess moisture.

Topical Treatments: Use an antibacterial and antifungal cream such as Mudbar Plus. Avoid using harsh substances that can further damage the skin.

Consult a Veterinarian: In severe cases or if the condition worsens, seek veterinary advice to ensure proper care and treatment.


Final Thoughts

Mud fever may be a common condition, but it is entirely preventable with the right care and attention. By staying vigilant, maintaining a clean environment, and protecting your horse from prolonged exposure to wet conditions, you can significantly reduce the risk of this troublesome skin ailment. A proactive approach ensures your equine companion remains comfortable and free from the pain and discomfort associated with mud fever.
