Cattle (colloquially cows) are large domesticated ungulates. They are the most widespread species of the genus Bos, most commonly classified as Bos primigenius. Cattle are raised as livestock for meat (beeg 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 formanure or fuel. In some countries, such as India, cattle are sacred. It is estimated that there are 1.3 billion cattle in the world today. In 2009, cattle became the first livestock animal to have its fenome mapped.
