Assuming there's any truth to that story . . . I've heard some cows are fed magnets, which stay in (one of) their stomachs. The magnets attract & hold ferrous metal, preventing some kind of problem (Intestinal damage? Weird flavored milk? I wonder if this would cause cows to line up with the earth's magnetic field? Maybe the position of least discomfort?
