What tool is specifically used for removing horns from cattle?

The tool specifically designed for removing horns from cattle is known as a dehorner. This instrument is specially crafted to safely and efficiently remove horns, minimizing stress and discomfort to the animal when performed correctly. Dehorners can come in various forms, such as scoop dehorners, which remove the horn and some surrounding tissue, and electric dehorners, which use heat to cauterize and remove the horn. This makes them essential for livestock management, as proper dehorning can help prevent injury among animals and handlers, and may reduce the risk of bruising during transport.

Other tools listed serve different purposes. Clippers are primarily used for trimming hair or fur, not for horn removal. Shears are cutting tools that might be used for various cutting tasks, but they are not tailored for handling horns specifically. A drench gun is used for administering liquid treatments or medications to livestock and does not relate to horn removal at all. Hence, the dehorner stands out as the correct choice for its specialized function in horn management for cattle.
