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. 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 Oil should be mixed with sulphur powder for use on mud fever and other scabbinesses. 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.
