Hornless cattle can be helpful because they pose less risk of injury to other animals and handlers. However, they may also be more vulnerable to predators and have limited defense mechanisms in some environments.
The Polled (Hornless) trait is caused by a dominant allele in domestic cattle. From the standpoint of many breeders the trait is a very favorable one, eliminating the need for dehorning andresulting in fewer injuries when new cattle are mixed into a herd. In cattle (even domestic varieties) that have to fend for themselves on the open range/in the wild, hornless cattle could be at a distinct disadvantage if they need to defend themselves from predators. A hornless bull, in the wild would be at a distinct disadvantage in a fight for dominance and the right to breed if the other male has horns.
