桃園種豬在台灣養豬事業中曾佔有重要地位，過去傳統上常以餿水、蕃薯藤、剩飯菜餵飼豬隻，因此飼養時間長且背脂厚，致民間日益棄養而有絕種之虞。92年桃園豬保種計畫開始進行皺紋觀察，桃園豬出生一日、一週與一月齡仔豬身體皮膚光滑，臉部眼框周圍已有明顯且固定的放射狀皺紋，與一日齡杜洛克及藍瑞斯仔豬臉部平滑比較有明顯差異。二月齡桃園豬額頭皺紋由放射狀直條型改為漩渦狀塊狀型皺紋，且隨日齡增加皺紋逐漸加深加大，呈老態狀。出生一日齡桃園仔豬尾部開始出現圈狀皺摺，直到二月齡尾部圈狀皺摺開始增多且紋路明顯。一月齡桃園豬腹部下垂呈圓球狀，二月齡腹部下垂明顯，至三月齡開始部分桃園豬腹部有幾近垂地情況，且背凹出現，四月齡體型加長但體高較洋種豬短，且背凹明顯。

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.
