Corkscrew claw is most common in which breeds?

• A. Hereford
• B. Angus, Holstein
• C. Jersey
• D. Ayrshire

Answer: (B)

Corkscrew claw is a hereditary hoof deformity in cattle, with a stronger association to breeds that have been intensively bred for production. Holstein cattle, the classic high-production dairy breed, show a notably higher incidence of this condition, and Angus—though a beef breed—also has documented genetic susceptibility in some populations. Among the breeds listed, the combination that best reflects the breeds with greater reported risk is Holstein paired with Angus, making that option the most likely to be affected. Other breeds in the list have less consistent or lower reported association with corkscrew claw in standard veterinary references.
