Nose rings make it easy to handle the bulls.
Some bulls wear nose rings to make them easier to handle. An adult bull can be an extremely dangerous animal that poses a serious threat to its handlers, and wearing a nose ring increases the level of control over the bull, making it safer to be around. In fact, ranchers boast that a child can safely drive a bull with a nose ring, although testing this claim in the field is not recommended. Rings can also be used on other livestock, especially the ring.
The classic nose ring used on bulls is hinged for easy opening, insertion, and locking. It is installed when the animal is about eight months old, usually by a veterinarian who applies a local anesthetic to the nose before drilling a hole and then threading the ring closed. Nose tissue is very sensitive, so a light tap on the ring can be a powerful signal for the bull to use it.
For safety, the electrodes are usually attached to the ring and a halter, providing two methods of control. Two handles can be used for added security. When a bull is led by the nose, he tends to follow and is generally not inclined to attack his handlers. If a bull starts acting up, a strong pull will be used to remind him that the humans are in charge.
In addition to wearing permanent nose rings, bulls can also be controlled with bull or bulldog tongs, a form of clip used for temporary handling. These styles are also used to bring general cattle into the ring, allowing handlers more control without the need to install and maintain a permanent ring. Specialized weaning rings are also sometimes used to aid in the weaning process on farms where calves and their mothers are not separated.
Nose rings are normally installed by a veterinarian for safety reasons and for the health of the bull. The process involves creating a deep puncture wound in sensitive tissue, and correct placement of the ring is important. Anesthesia also helps keep the bull more comfortable while the ring is installed. The vet may need to return to check the fit and replace the ring if necessary. Multiple handles are also required for the placement of a ring, along with very sturdy restraints to hold the animal in place.
