Abstract: Disclosed herein is a device for holding the head of cattle, livestock, and the like while the head of the animal extends through plural vertical rails which are laterally translatable, such rails commonly being used today to serve as a barrier one side of which the animals can find, of which is the feeding area of the livestock. The rails are caused to constrict the animal's head preventing withdrawal of the head by being more closely spaced, and thereafter the device according to the present invention is applied by hooking two ends of a pivot member between two successive rails and applying a snout engaging device on the animal, the device including a lever for forcing the animal's head in a constrained and still position against the rails and the device so that successive operations such as dehorning, medicating or the like can be administered to the animal while the animal's head remains stationary.
