What characteristic is common in Hampshire hogs?

Hampshire hogs are notably recognized for their distinct coat pattern, specifically their black body with a white belt around their shoulders. This characteristic is a defining breed trait and helps to differentiate them from other pig breeds. The white belt provides an easily identifiable appearance, which is important in both breeding and market contexts.

The other options do not accurately represent the Hampshire breed. While large ears can be a trait seen in various pig breeds, Hampshire hogs typically have medium-sized erect ears. Furthermore, red coloration is characteristic of other breeds, such as Durocs, rather than Hampshires. The term "urgent temperament" does not apply universally to the Hampshire breed and is not a recognized characteristic used in identifying or describing this breed. Therefore, the black body with a white belt stands out as the defining and prominent characteristic of Hampshire hogs.
