The female of this kind of animal is called a "cow," the male is a "bull," and their offspring is a "calf."
Sometimes the term "cow" is used in a general way to refer to all kinds of cattle.
In some cultures, cattle are traded in exchange for goods. Sometimes they are used as gifts given to the parents of a young woman a man desires to marry.
