The Rhinehart Electric Dehorner will do a good dehorning job on any calf that does not have a horn larger at the base that the inside of the Dehorning ring (7/8 in to 5/8 in tapered inside diameter.) Dehorning should be done as soon as the horn button can be located. The younger te calf, the less effort and time required for a good dehorning job. A) The Dehorner should be applied for at least 10 seconds to make sure ALL horn cells in hair line around the horn base are killed. B) A dry scab will form over the seared area. The scab and horn button will later drop off. This will take several weeks. Let it heal off - don't pull it off. C) Electric dehorning is preferred over other methods. It is safe, fast and efficient. Dehorn calves as soon as horn button can be located - the younger the calf the better.
