To improve the taste of pork,pigs must keep good physical shape. This convinced the Chinese farmer Huang Demin from the southern Chinese province of Hunan. He taught his pigs to jump from the tower.

Swimming and a few additional exercises improve the immunity of animals and improve meat quality. Farmer built a three-meter wooden platform at the pond near his sty in the county of Ningxia so that the pigs could dive every day. After these water treatments pigs appetite increases and they grow faster, says the farmer. Moreover, the farmer can sell his flying pig meat at a price three times higher than conventional meat. A tower of his own making has become a local landmark.
