Pig Oil is a useful, traditional method of controlling mud fever in horses and ponies by helping to create a barrier to wet conditions around the legs and preventing cracked heels.
Pig Oil also prevents the feathers snapping due to wet & muddy conditions - the 'Bog Burn'. Also lice dislike greasy environments so they are less likely to infest your horses legs.
Pig oil is a mineral based oil that includes liquid paraffin.
Pig Oils uses on mud fever and other scabbinesses. Mix the oil with some sulphur powder. Make it in to a paste of the consistency of custard and massage on to the scabs. In a few days they will be gone. To prevent mud fever, make a very thin mixture and get it right up next to the skin.
