 affects young cattle. It most commonly occurs in the region of 

 the face and neck. Thick, bran-like crusts form over the scattered 

 areas of the skin and the hair drops out or breaks off. The

 animals and scrubbing the stalls, stanchions and walls with a 

 disinfecting solution. Grooming the infected animal should be 

 discontinued. This skin disease responds most readily to oint- 

 ments. Flowers of sulfur one part and lard ten parts is com- 

 monly used by stockmen. Sulfur-iodide ointment, or tincture 

 of iodine may be applied.
