Which of the following is a common breed of hog that is all white?

The Yorkshire breed is well-known for its distinctive all-white coloration and its popularity in pork production. This breed is recognized for its excellent mothering abilities and high-quality meat, making it a preferred choice among farmers and breeders. The white color is a key characteristic of Yorkshires, which differentiates them from other breeds that might have different color patterns or markings.

In contrast, Duroc hogs typically have a reddish-brown color, while Pietrain hogs are recognized for their unique pattern that includes spots of black and white. Hereford pigs characteristically have an identifiable coloration that features a red body with white face markings. Therefore, the all-white coat of the Yorkshire clearly distinguishes it as the correct answer to the question regarding common hog breeds.
