Dairy Cattle (cow) Royalty-Free Stock Image

Cattle is a word for certain mammals that belong to the genus Bos. Cattle may be cows, bulls, oxen, or calves. Cattle are the most common type of large domesticated hoofed animals. They are a prominent modern member of the subfamily Bovinae. Dairy cattle are kept and raised specially for milking. Herds of cows are kept and are regularly mated with a bull, so that they produce calves. This keeps the milk supply going.
