Which livestock species is known for having a "down" or droopy ear structure?

The most recognized livestock species with a "down" or droopy ear structure is swine. In pigs, the breed commonly associated with droopy ears is the Yorkshire, which is characterized by having ears that fall forward over their eyes. This ear structure can also be observed in other swine breeds, which gives them a distinct physical appearance compared to species like cattle, sheep, and poultry.

Cattle typically have upright ears, which are more mobile and help them to hear various sounds in their environment. Sheep may have ears that are less prominent at times but are not classified as droopy. Poultry, such as chickens, do not have ears in the traditional sense since they possess ear openings covered by feathers. Instead, they have combs and wattles, which are their distinguishing features. Understanding these differences helps clarify why swine are identified specifically for their droopy ear structure.
