Mud fever, more formally known as pastern dermatitis, is an extremely common concern for UK horse owners, particularly through the wetter autumn and winter months, and while management and prevention are the primary defences, nutrition plays a genuine supporting role worth understanding.
Mud fever develops when the skin around the lower limb, particularly the pastern area, becomes compromised, often through prolonged exposure to wet, muddy conditions that soften and weaken the skin's natural protective barrier. Once this barrier is compromised, opportunistic bacteria and other organisms, including Dermatophilus congolensis, can establish infection, leading to the characteristic scabbing, soreness and sometimes swelling associated with the condition.
Prevention through good management remains the primary line of defence. This includes minimising prolonged standing in wet, muddy conditions where practical, ensuring legs are properly dried rather than left wet after washing, and using appropriate barrier products on at-risk areas during particularly challenging weather, particularly for horses with known sensitivity or a history of mud fever.
Nutritionally, supporting overall skin health and resilience gives the skin a better foundation to withstand environmental challenges, even though nutrition alone cannot prevent mud fever in genuinely high risk conditions without appropriate management alongside it.
Zinc plays an important role in skin health and wound healing processes generally. Chelated zinc, a form that is more readily absorbed than some other zinc sources, is often included in products targeting skin and coat condition for this reason, supporting the skin's natural ability to maintain its protective barrier function and recover from minor irritation or abrasion.
Horses with naturally sensitive skin, those prone to recurring mud fever despite good management, or those living in particularly challenging wet conditions may benefit from additional nutritional support specifically targeted at skin resilience, used alongside, never instead of, sensible management practices.
It is worth being clear that nutrition is a supportive measure rather than a treatment for active mud fever. Once mud fever has developed, appropriate veterinary guidance on treatment, which may include gentle cleaning, topical treatments and in some cases prescribed medication for more severe or persistent cases, remains essential. Nutritional support is most valuably viewed as part of a longer term strategy to support skin resilience and potentially reduce recurrence, rather than an active treatment once infection has taken hold.
Mud Manager, formulated with chelated zinc, is designed to support healthy skin from within as part of this broader approach, working alongside good management practices rather than replacing the need for them, particularly for horses prone to recurring skin sensitivity during challenging wet weather periods.
