Corkscrew claw is most common in which combination of breeds?

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

Answer: (D)

Corkscrew claw is a hereditary claw deformity in cattle, so certain breeds are naturally more predisposed to it. Dairy cattle tend to show higher rates of this condition, and among dairy breeds, Holsteins are the most commonly affected due to their large numbers and strong genetic ties within production-oriented lines. Angus is a widely kept beef breed that is often found in crossbreeding programs with Holsteins in commercial herds, so the combination of these two breeds represents the pairing where the trait is most frequently observed. The other breeds listed are either primarily beef with lower reported prevalence for this specific issue or are less commonly implicated in the typical herds where corkscrew claw is tracked, making the Angus–Holstein pairing the best fit for where this condition is most commonly seen.
