Horse Mud Fever Prevention Welfare

Mud fever (pastern dermatitis) is a painful skin condition exacerbated by wet conditions that is largely preventable with good management.

Key Facts

Mud fever is caused by Dermatophilus congolensis and other organisms in wet conditions
White-legged horses and those with feathering are more susceptible
Underlying allergies or chorioptic mange mites can complicate treatment
Prevention through pasture management and leg drying is more effective than treatment

Welfare Considerations

Mud fever causes painful cracked, weeping, and scabbing skin that worsens rapidly without treatment. Horses with severe mud fever show lameness and significant discomfort. Prevention through pasture management and leg care is far preferable to treating established cases.

What You Can Do

Rotate grazing to prevent muddy gateways and high-traffic areas
Check horses' legs daily during wet weather and dry them when possible
Seek veterinary advice early if mud fever develops rather than waiting
