Best Age for Dehorning in Calf
Best age of dehorning/disbudding in calf is:
- 3-10 days — Correct Answer
- 10-20 days
- 20-30 days
- 30-40 days
Explanation:
Correct Answer: 3-10 days
The best age for dehorning/disbudding in calves is before 10 days old (3-10 days). Up to this time, the horn button does not attach to the skull, making the procedure less painful and easier.
Methods of Dehorning
- Chemical method: KOH (Caustic Potash) is applied to the horn bud
- Electrical method: Electric dehorner at 1000°F for 10 seconds
- Mechanical method: Clipper saws or rubber bands
Why Other Options Are Wrong
- 10-20, 20-30, 30-40 days: After 10 days, the horn button begins to attach to the skull, making dehorning more difficult, painful, and risky. The procedure should be done as early as possible.
