Cows are mainly farmed for their milk, which is taken from the farm by refrigerated tankers and brought to a factory. There, the milk is pasteurized by heating it to 71 degrees Celsius for 15 seconds to kill bacteria before being bottled or packaged for sale. Dairy cows need to have a calf each year to produce milk for human consumption. The calves are either raised as future dairy cows or for beef production.
