Which device operates as an electric dehorner?

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

Answer: (B)

Electric dehorner works by applying heat to the horn buds as it removes the horn tissue, cauterizing the area to seal blood vessels and help prevent regrowth. This makes it the appropriate choice when the question asks for a device that operates as an electric dehorner. The other tools are manual or surgical: a dehorning scoop or spoon is used to gouge out horn tissue by hand, a Barnes dehorner is a manual cutting instrument that removes horn tissue, and a scalpel is a surgical blade used for precise cutting without heat. Using the electric dehorner provides a faster, cauterized result when used correctly on young calves.
