Beef cattle are bred and raised specifically to provide meat or beef. "Steers" are the best type for this purpose because they can be kept in herds without fighting each other. "Heifers" are also often used for beef, especially those that are not suitable to be used in a breeding herd. The cows of beef cattle are used to give birth to and raise calves for meat. They are not usually used for milk, although some types of cattle, such as the Red Poll, Dexter or Red Devon (also known as the North Devon or Devon) are used for both. These type of cattle are called dual purpose breeds.
