Bull calves intended for breeding are sometimes nose-ringed in order to facilitate easy handling of the bull. Nose rings are commonly used as a means of control and training for bulls. They are attached to a rope or chain that can be pulled to lead the bull or to control its movements. The nose ring helps to calm the animal and prevent it from becoming aggressive or difficult to handle. Additionally, nose-rings may be used to help identify individual animals or to prevent them from damaging fences or other objects.
