Virgin bulls

A virgin bull is a bull less than 18 months of age in which one permanent central incisor teeth is in wear and that has never been commingled with breeding females. Virgin bulls, other than exhibition and rodeo bulls, brought into this state or transferred within the state, shall, in addition to any other required documentation, be accompanied by a certification of virgin status signed by the owner of the bull, or the owner’s representative or a duly authorized Veterinarian. Certification shall include the bull’s individual identification. If the virgin bull was acquired from an individual other than the original breeder then a certification of virgin status signed by the breeder and each prior subsequent owner of the bull, or their representative must also accompany the bull. This certification can be stated on the CVI or can be an official state form that accompanies the CVI and sent to our office.

Virgin Bull Statement
“ I certify that these bulls have not been exposed to female breeding animals since weaning.”

  1. All samples to be submitted for testing for Trichomoniasis shall be drawn by a certified accredited veterinarian and testing performed by an approved laboratory.
  2. Approved Tests are those that have been approved by a laboratory that is accredited by the American Association of Veterinary Laboratory Diagnosticians (AAVLD) using approved protocols and supplies.  The Polymerase Chain Reaction test (PCR) is the official test. Up to 5 samples may be pooled if requested.  The pooling must occur at the laboratory.  The tests must be conducted no more than 60 days prior to entry of the bull into this state and 90 days for transfer within the state, provided that the bull has not been comingled with female cattle.
  3. A positive result on any test shall immediately cause the bull to be classified as a Trichomoniasis infected bull subject to the restrictions set out in these regulations.
  4. A second PCR test to confirm the presence of Trichomoniasis may be requested in the event of a positive result on a test, but the request for the confirmatory test must be made within 5 days of notification of the positive test result.
    1. If the confirming PCR test comes back negative then one more negative test shall be conducted for the bull to be considered negative for Trichomoniasis and be moved as a negative bull.
    2. If the confirming PCR test comes back positive then the bull shall be considered to be infected and subject to the restrictions set out in these regulations.
  5. Bulls being tested for Trichomoniasis shall be kept separate from female cattle at all times during the entire test period and from the completion of the test until importation into this state or transferred to another herd within the state
  6. All positive test results for Trichomoniasis shall be reported to the state veterinarian within 24 hours after receipt of the results. When a positive test result is received the treating veterinarian shall consult with the state veterinarian on the first business day after receipt of the test results to determine a plan of action regarding the herd of the animal testing positive.
