Horse Mud Fever Prevention and Management

Pastern dermatitis (mud fever) is a painful skin condition in horses caused by prolonged exposure to wet, muddy ground.

Key Facts

Mud fever is caused by bacteria including Dermatophilus congolensis
It affects the lower limbs, causing scabs, swelling, and lameness
White-legged horses are more susceptible due to reduced skin pigmentation
Prevention requires managing pasture to avoid standing water and mud
Treatment involves gentle cleaning, antibacterial treatment, and keeping legs dry

Welfare Considerations

Mud fever causes significant pain, lameness, and secondary infection when untreated. In wet climates horses are particularly vulnerable during winter. Good pasture management, rotation, and early treatment protect horses from this avoidable condition.

What You Can Do

Implement track systems or hard standing to reduce mud exposure
Inspect horses' legs daily in wet conditions for early signs of mud fever
Consult a vet promptly if scabs, swelling, or lameness appear
