DESCRIPTION:
Cow are the most common type of large domesticated ungulates. They are a prominent modern member of the subfamily Bovinae, are the most widespread species of the genus Bos, and are most commonly classified collectively as Bos primigenius. Cow are raised as livestock for meat (beef and veal), as dairy animals for milk and other dairy products, and as draft animals (pulling carts, plows and the like). Other products include leather and dung for manure or fuel. In some countries, such as India, Cow are sacred. It is estimated that there are 1.3 billion Cow in the world today. In 2009, Cow became the first livestock animal to have its genome mapped.
A milkmaid or milk maid is a girl or woman employed to milk cows. She also used the milk to prepare dairy products such as cream, butter, and cheese. The term is not a female equivalent of milkman and is now largely obsolete due to the use of automated milking machines in the modern dairy industry and because milking cows is no longer considered to be exclusively "women's work".
The expression "as smooth as a milk maid's skin" means exceptionally smooth. This phrase came about as a result of exposure to cowpox, which causes no serious symptoms, but does convey a partial immunity to the disfiguring (and often fatal) disease smallpox. Thus, milkmaids lacked the "pockmarked" complexion common to smallpox survivors. This observation led to the development of the first vaccination.
