Some farmers put rings (called choat rings if I spelled that right) in their pigs noses to stop them from rooting in the dirt. The rings are C shaped when open and sharpened at both ends, they are applied with a specalized tool that clamps the ring closed onto the edge of the hogs nose and the result is that it is painful if they try to root at the ground. Rooting in the dirt can potenially lead to parasights and the passing on of disease .
