Dehorning

 

the artificial removal of horns or the prevention of their growth. Dehorning is primarily performed on cattle and rams to prevent injuries and to prevent diseases of the horns. In order to prevent horn growth in calves, various chemical substances, such as alkalis, sulfuric acid, and trichloride solution, are rubbed into the rudiments of the horns in the first three to 15 days after birth. In calves 30–60 days old, the rudimentary horn is excised with a tubular scalpel. In adult animals, a bloodless method is used in which a rubber ring is applied at the base of the horns; in 28–47 days, the horns atrophy and fall off. An electrical or wire saw can also be used, but this is not a bloodless method. Dehorning is contraindicated in the second half of gestation.
