Which dehorning method is NOT preferred for cattle two months of age or younger?

• A. Caustic paste
• B. Electric dehorner
• C. Horn punch
• D. Scoop dehorner

Answer: (D)

In very young calves, the aim is to destroy horn tissue while minimizing trauma to a still-developing skull. A scoop dehorner works by scooping out horn tissue, which creates a relatively large wound and can be too aggressive for calves two months old or younger. Their skulls are thin and the horn buds are small, so using a scoop poses a higher risk of skull injury, brain damage, or excessive tissue damage. More suitable options for this age include caustic paste, which chemically destroys horn tissue without cutting; an electric dehorner, which uses heat to halt horn growth quickly and with controlled tissue removal; or a horn punch, which surgically removes the horn bud tissue in a precise manner with proper restraint and analgesia. Because of these safety considerations, the scoop dehorner is not preferred for calves this young.
