Cows

Cattle were domesticated in humanity's neolithic past. They were and to this day are still raised for such things as meat, milk, and hides. Cows were used by ancients as the world's first draft animals. They aided in the neolithic agricultural revolution by allowing farmers to cultivate fields with plows. Cattle are usually raised on vast tracts of grassland, or ragneland unsuitable for farming. In modern times such procedures as eartagging, dehorning, vaccinating, and hoof care are conducted to make sure the cattle mantain their health. Selective breeding is done to ensure the healthiest and meatiest specimens. Cows are cited as responsible for 18% of the world's greenhouse gases.
