What physical trait, required by the Welsh Black Cattle Society, relates to horn presence?

Answer

Natural polling (hornlessness)

Adherence to specific phenotypic standards is crucial for registering a Welsh Black calf with the Welsh Black Cattle Society. While the coat must be predominantly solid black (with minor exceptions for white on the head, udder, or scrotum), a key required physical marker is natural polling, meaning the animal must be hornless. This adherence to specific physical markers, including hornlessness, is the mechanism used by breed societies to maintain the distinct identity of the Welsh Black subset within the larger Bos taurus umbrella.
