Cows are the most common type of large domesticated ungulates. Cattle are raised as livestock for meat (beef and veal), as dairy animals for milk and other dairy products, and as oxen or bullocks that pull carts, plows and other implements. Other products include leather and dung for manure or fuel. Beef is the culinary name for meat from bovines, especially cattle. Its acceptability as a food source varies in different parts of the world. Some consider cattle the oldest form of wealth.
