From Pig

The Duroc are a breed of pig that had its origin in the eastern United States and in the Corn Belt.

Durocs have considerable variation in color. An acceptable color may range from a very light golden, almost yellow color, to a very dark red that approaches mahogany. The red is a very practical color that suits pork producers, and since it is a solid color there is not concern about fancy points of proper markings. Durocs have a medium length and slight dish of the face. The ears should be drooping and should not be held erect.
