In a farm deep in the southern region of China lives a pig that is as heavy as a polar bear.

The 500-kilogram (1,100-pound) animal is part of a herd that is being bred to become giant swine. At slaughter, some of the pigs can sell for more than 10,000 yuan ($1,400), over three times higher than the average monthly disposable income in Nanning, the capital of Guangxi province, where the farm's owner, Pang Cong, lives.

While Pang's pigs may be an extreme example of the lengths farmers are going to fill China's swelling pork shortage problem, the idea that bigger is better has been spreading across the country, home to the world's most voracious consumers of the meat.
