The combination of caustic substances in dehorning paste cauterizes tissue and prevents horn growth.
A long piece of wire is attached to two handles, then moved back and forth rapidly to saw through the horn base plus a ½-inch circle of skin.
In this method of dehorning, a hand saw is used to remove the horn along with a ½-inch ring of skin around the horn base.
An iron is heated to red hot, then held firmly to the horn bud for about 20 seconds, destroying the horn-producing cells and preventing further growth.
A keystone dehorner has two handles that move a blade downward against a plate or another blade, slicing through the base of the horn and surrounding skin.
In this dehorning method, a knife is used to cut away skin around and under the horn bud, surgically removing the horn from the base tissue.
A Barnes dehorner is a hinged, closed set of sharp scoops which is placed over the horn against the base and surrounding skin.
A circular blade is pushed into the skin around the horn bud, then rotated and tilted to gouge out the horn.
