[Dehorning of calves using the Leister-Ghibli hot air pistol].

The present study was concerned with the applicability and efficiency of the Leister-Ghibli hot-air gun used in disbudding calves. The tool was used in thirty-three calves averaging an age of seven weeks. Subsequently, none of the calves showed growth of horns. When the burning time is 20-25 seconds, the depth effect of the hot air is mainly limited to the epidermis and, at the same time, suffices to prevent the growth of horn.
