Section 100.025 - Classification of dairy heifer calves(1) As used in this section, "dairy heifer calf" means a female bovine animal, of a recognized dairy breed, at least 2 weeks and less than 4 months of age.(2) The owner of the herd of origin of any healthy dairy heifer calf may classify such calf as a "Wisconsin Blue Tag" dairy heifer calf by certifying that he or she is the owner of the herd of origin; that the sire of such calf is a registered purebred sire; and that the dam is of the same breed as the sire. Such certification shall be on forms prescribed by the department and shall include identification of the calf and its sire and dam, and such other information as the department requires. Dairy heifer calves so classified shall be identified by the owner of the herd of origin or the owner's agent by inserting a blue ear tag in the right ear and shall be accompanied by the certificate.(4) Blue ear tags for dairy heifer calves shall be purchased from the department. Each tag shall bear a distinctive serial number. No person shall possess or use, for identification pursuant to this section, ear tags which have not been issued by the department. Ear tag applicators and other supplies may be purchased from the department.(5) No person shall falsely execute any herd owner's certificate or falsely represent the identity or classification of any calves provided for in this section.1991 a. 201; 1993 a. 492.
