Cattle (colloquially cows) 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. Cattle 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, cattle are sacred. It is estimated that there are 1.3 billion cattle in the world today. The cow’s diet consists of grass and hay. In fact, the cow is one animal that has a complex stomach that allows it to digest grass. They chew the cud, meaning they re-chew the food that they’ve already eaten. The gestation period for a cow is nine months. A newborn calf weighs 25 to 45 kilograms (55 to 99 lb).
On average, a cow spends six hours eating and eight hours chewing its cud. Cows can live for over 20 years.
