Dehorning methods vary by age of animal and stage of horn development. Disbudding methods such as caustic paste and hot-iron can only be used in calves under two months of age, before the horns attach to the skull. Mechanical dehorning methods can be used on horns at any stage of development. Each method has advantages and disadvantages. Producers should consult their veterinarians to determine the dehorning method that’s best for the animal and the operation.
