Cow

Cattle are raised as livestock for meat (beef and veal), as dairy animals for milk and other dairy products, and as draft animals (oxen / bullocks) (pulling carts, plows etc). Other products include leather and dung for manure or fuel. It is estimated that there are 1.3 billion cattle in the world today.

The gestation period for a cow is nine months. Breeding stock usually live to about 15 years (occasionally as much as 25 years). Cattle are ruminants which means that they have a digestive system that allows use of otherwise indigestible foods by regurgitating and rechewing them as "cud". The cud is then re-swallowed and further digested by specialized microorganisms in the rumen.

The cow is 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.
