Taoyuan pig had ever played an important role in Taiwan’s swine production. Traditionally the pig was raised by kitchen waste, potato, and vine sweet and due to a longer raise period, pigs had a thicker back fat. Therefore the pig was eliminated gradually and faces a risk of extinct. In the Taoyuan pig conserve project of 2003, the formation of wrinkle has been observed and showed that the forehead of Taoyuan piglet at birth already had significant wrinkles compared with Duroc and Landrace of the same age, and the wrinkle type was observed from radiant straight to zigzag curve by growth. The tail of Taoyuan piglet at birth showed circular wrinkle, besides the number and depth were gradually increased from the 2nd month. Taoyuan piglet on the 1st month already had a fallen abdomen, and the transformation of fallen belly became more obvious by raising. While Taoyuan pig was three months old, the sunken back was generated and the belly was nearly touched to the ground.
Key Words: Taoyuan pig, Wrinkle observation.
