What does the term "polled" mean in livestock?

In livestock terminology, the term "polled" refers specifically to animals that have never had horns and do not possess the genetic capability to grow them. This characteristic is common in certain breeds and has been selectively bred for various reasons, including safety and management ease. Polled livestock are often considered desirable because they pose less risk of injury to other animals and handlers.

Understanding this term is important for breeders and farmers, as it can influence breeding decisions and herd management practices. The other choices do not align with the definition of "polled"; for instance, simply having a large body size, being used for breeding purposes, or being defined by specific breed types does not capture the essence of what "polled" specifically denotes.
