Evaluation of Freeze-branding as a Marking Technique for Wild Swine

Adult and immature wild swine (Sus scrota) were marked using freezebranding. Irons were applied for various durations to determine the most appropriate branding time. Light-colored skin and a permanent hair loss were produced by iron application times of 100 to 120 sec for adults and 20 to 24 sec for immature animals. Marks were permanent and readable up to 100 m.
