The Lamb/Kid Restraint, which consists of a size-adjustable holding tube and a work tray, is designed to make vaccinating, ear tagging, docking, castrating, etc., a one-person job. Simply sliding the animal into the tube frees both hands to perform whatever the task(s); the tray keeps supplies within easy reach. The device is available as either a pen panel-mounted model or a movable stand-mounted model.
