Domestic Cattle, often informally refered to as a Cow or Cows Aberdeen Angus is a beef cattle breed.
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.
Many species of oxen are still around. They are used for many purposes in China and in other developing countries.
