nose ring

A nose ring is a ring made of metal designed to be installed through the nasal septum of pigs (to prevent them from rooting) as well as domestic cattle, usually bulls. In pigs, nose rings are alternatively installed through the rim of the nose. Nose rings are often required for bulls when exhibited at agricultural shows. There is a clip-on ring design used for controlling and directing cattle for handling. Nose rings are used to encourage the weaning of young calves by discouraging them from suckling.
