Cattle are a bovine mammalian quadruped that were domesticated during pre-history as a source of meat and leather. Its excrement (when dry) is a useful fuel source. The female "cow" is also able to give milk and the male "bull" is often used as symbol for the property of strength. The word "cow" is also commonly used in the English vernacular to refer to any individual cattle. A calf is a sexually immature cow of either sex.
They are relatively placid and tend to herd for mutual protection. This provides labour opportunities for cowherds and milkmaids.
