Which instrument is commonly used for dehorning cattle?

• A. Electric Dehorner
• B. Barnes Dehorner
• C. Dehorning Scoop or Spoon
• D. Newberry Knife

Answer: (B)

Barnes dehorner is the instrument designed specifically for removing horn buds in young calves, making it the most efficient and reliable tool for dehorning. It fits around the horn bud and allows a clean, controlled removal with minimal tissue damage, often paired with cautery to help prevent horn regrowth. This specialization makes it the best choice for the common dehorning task.

Electric dehorner uses heat to cauterize and remove horn tissue, which is effective in many settings but depends on electricity and technique. The dehorning scoop or spoon is a supportive tool used to remove horn tissue but isn’t the primary instrument for the initial removal. The Newberry knife is a general surgical blade used for incisions in various procedures and isn’t tailored to efficiently disbud or dehorn cattle.
