Bulls have nose rings primarily as a safety and control measure. The nose is a sensitive part of the bull's body, so a ring pierced through the septum allows a farmer to lead or control the animal by applying gentle pressure or pulling on the ring. This causes discomfort to the bull if it resists, making it easier to handle large and often aggressive bulls safely. The ring can also help limit aggressive movements or be attached to a rope to prevent charging behavior. This practice is also used to help wean calves by using clip-on nose rings that discourage suckling. Nose rings are not for fashion but serve practical purposes in managing livestock behavior and safety during handling.
