Résumé
A nose ring is inserted into the nose of an animal. Nose rings are used to control bulls and occasionally cows, and to help wean young cattle by preventing suckling. Nose rings are used on pigs to discourage rooting. Some nose rings are installed through a pierced hole in the nasal septum or rim of the nose and remain there, while others are temporary tools.
Historically, the use of nose rings for controlling animals dates to the dawn of recorded human civilization. They were used in ancient Sumer and are seen on the Standard of Ur, where they were used on both bovines and equines. There are theories that the rod-and-ring symbol are a shepherd's crook and a nose rope.
Calf-weaning nose rings are anti-suckling devices. These nose rings (usually made of plastic) clip onto the nose without piercing it, and are reusable. They provide an alternative to separating calves from their mothers during the weaning period. They have plastic spikes which are uncomfortable for the dam when her calf presses against her udder, causing her to reject the calf's efforts at suckling. Use of calf-weaning nose rings reduces the stress of weaning by separating it into two stages. First, the calf is weaned from suckling milk — this stage usually lasts up to 14 days. Then later the calf is separated from its dam. Weaning nose rings are also available for sheep and goats.
The nose ring assists the handler to control a potentially dangerous animal with minimal risk of injury or disruption by exerting stress on one of the most sensitive parts of the animal, the nose. Bulls, especially, are powerful and sometimes unpredictable animals which, if uncontrolled, can kill or severely injure a human handler.
Control of the bull may be done by holding the ring by hand, attaching a lead rope to it, or clipping on a bull staff or bull pole. A rope or chain from the ring may be attached to a bull's horns or to a head-collar for additional control. A short length of chain or rope may be left hanging loose from the ring of an aggressive bull, so when he ducks in a threatening manner the bull will step on the chain and be deterred from attacking.
