When preparing ear marks used by being attached to ears of livestock for identification of livestock, multiple-digit livestock registration number (CN) is printed on at least one face of each ear mark and a farm number (FN) in least necessary digits according to a desired number for ease of livestock identification in each farm is magnified and printed. The magnified farm number (FN), which is printed by being extracted from a random part of the relative livestock registration number (CN), can be generated efficiently from the livestock registration number. |
