What physical characteristic sets apart Duroc Swine?

• A. All black coloration
• B. Red color with erect ears
• C. White body with black spots
• D. Black with a white belt

Answer: (B)

The distinguishing physical characteristic of Duroc Swine is their red color and erect ears. This breed is known for its reddish-brown coloration, which can vary from light to dark shades but is predominantly recognized as a rich red. The erect ears add to their unique appearance and are a notable feature that helps in identifying them among other swine breeds.

In contrast, the other options describe characteristics of different breeds. For instance, all black coloration is typically associated with breeds like the Berkshire or the Landrace, whereas the white body with black spots describes the Spot or similar breeds. The black with a white belt is a trait of the Hampshire breed. Thus, the distinct red color coupled with the erect ears serves as the identifying hallmark of Duroc Swine.
