<P> Pigs are farmed in many countries , though the main consuming countries are in Asia , meaning there is a significant international and even intercontinental trade in live and slaughtered pigs . Despite having the world 's largest herd , China is a net importer of pigs , and has been increasing its imports during its economic development . The largest exporters of pigs are the United States , the European Union , and Canada . As an example , more than half of Canadian production ( 22.8 million pigs ) in 2008 was exported , going to 143 countries . Older pigs will consume eleven to nineteen litres ( three to five US gallons ) of water per day </P>
