Any idea what would start out as black spots ranging in size from pencil eraser to the size of your little finger on the backs of calves? Eventually the cattle lose some hair on their backs (maybe from rubbing). In the worst case, calves get sores on their backs and lose some hide. Screw eye spray seems to stop it for getting worse, but doesn't return the hide to the way it was. Calves don't lose their appetite or lose weight.
