US EditionSouth Dakota cattle producer discovers rare three-hoofed calf
- David Murphy discovered a rare three-hoofed calf during a routine calving check at his White, South Dakota operation.
- The calf's unusual condition is caused by a genetic defect called polydactyly, which Murphy had not encountered before.
- Veterinary pathologist David Steffen explained that polydactyly means extra digits and often results from a mutation occurring early in embryonic development.
- Steffen advised against breeding animals that show this condition, as they carry the genetic trait and have a high chance of passing it on to their progeny, highlighting the importance of reporting such cases.
- Lack of a centralized polydactyly reporting system in North America makes it difficult to assess its rarity, though research is expanding with more affordable DNA sequencing.
