Someone please help me – I have no idea what to do and am getting quite desperate!! My boy (fully feathered h/w cob) suffers badly from mallenders/mud fever, he gets horrible scabs behind his knees (fronts only, hinds have so far been clear). He is on strict pig oil and sulphur regime (applied every two weeks since October to all four legs) which seems to help a bit in that most of the scabs (but not all) fall off. When the scabs get very bad I have also applied aromaheel which also seems to help a bit though makes a right mess of the feather and is difficult to apply. However, no matter what I do the scabs keep on returning and seem to be getting worse each time. So far my boy has been sound but lately I have noticed that he has started getting some heat in his legs where the scabs are. His hair has also stopped growing in the scabby bits (though you can only notice it by lifting the feather on top) and he seems more impatient during his fortnightly oil applications, though whether this is due to pain or boredom I am not sure. Does anyone have any other suggestions as to what I should do to stop/treat the scabs or am I fighting a losing battle? The scabs are limited to behind his knees only, his legs and heels are otherwise clear so it’s no ordinary mud fever as he hardly gets a spot of mud on him these days with all the oil dripping down his legs!
