N.M. Admin. Code § 21.30.6.10

Current through Register Vol. 35, No. 17, September 10, 2024

Section 21.30.6.10 - VOLUNTARY NEW MEXICO T.foetus FREE HERD CERTIFICATION REQUIREMENTS - MAY BE AN INDIVIDUAL HERD, RANCH, GRAZING ASSOCIATION OR FEDERAL LAND PERMITEE

A. Breeding bulls.

(1) All non-virgin breeding bulls shall be tested annually for T.foetus for the three (3) years following the adoption of this rule.

(2) During the three year inception period, all non-virgin breeding bulls with changes of ownership, leased, rented or otherwise, shall be tested for T.foetus within sixty (60) days prior to such change unless consigned direct to slaughter. The test will be completed and test results known prior to the time a bull is physically transferred to the receiving premises or herd.

(3) Negative T.foetus bulls will be identified with the official New Mexico negative T.foetus tag described in the identification section of this part.

(4) All slaughter bulls removed from the herd will be tested for T.foetus. The test may be performed at a slaughter facility if prior arrangement with a veterinarian and an appropriate agreement with the slaughter facility management is made.

(5) Bovine females added to a certified herd shall not originate from a known T.foetus infected herd. Female herd additions must originate from a New Mexico certified T.foetus-free herd or qualify in one of the following categories:

(a) calf at side and no exposure to other than known negative T.foetus bulls;

(b) checked by an accredited veterinarian, at least one hundred twenty (120) days pregnant and so recorded;

(c) virgin; or

(d) heifers exposed as virgins only to known negative T.foetus infected bulls and not yet one hundred twenty (120) days pregnant.

(6) Records must be maintained for all tests including all non-virgin bulls entering the herd and made available for inspection by an accredited veterinarian or state animal health official.

(7) Following successful completion of the three-year testing requirement, the participating entity shall receive a T. foetus-free certification from the New Mexico state veterinarian's office. Annual re-certification will require documented evidence that all male herd additions were virgin or that non-virgin breeding bulls added to the herd had three (3) official negative T.foetus tests within sixty (60) days prior to commingling with female bovine and that all slaughter bulls removed from the herd have been negative for T.foetus prior to or at slaughter.

(8) A herd in which a bull has a confirmed T. foetus infection will be classified as a positive T.foetus herd and shall be removed from the "free" status. The herd will be quarantined until positive T. foetus bulls are sent to slaughter and all other bulls in the herd test negative to three (3) consecutive official T.foetus tests at least seven (7) days apart. The third T.foetus test will be completed within twelve (12) months of the initial T.foetus confirmation in the herd and will be conducted after the bulls have had breeding exposure to the cow herd. The bulls will be removed from the cow herd at least seven (7) days prior to the official T. foetus test. If more than twelve (12) months have passed since confirmation of T.foetus in the herd, the state veterinarian may require additional T.foetus testing prior to release of quarantine. The initial negative T.foetus test is included in the three (3) negative tests.

B. A non-tested, non-virgin bull that commingles with a herd that holds or is actively working toward the New Mexico certified T.foetus-free status, by fence breach or any commingled situation, shall obligate the owner of the non-tested bull to test the bull from one to three times at the option of the state veterinarian in consultation with the owner and veterinarian of the negative herd.

C. A bull from a herd which holds a current or has pending a T.foetus-free certification and which commingles with a non-tested herd, shall undergo one to three official T.foetus test(s) prior to return to his herd of origin. Shall such test be positive, all bulls from both herds may be subject to testing. The state veterinarian in consultation with the herd owner and herd veterinarian will determine the appropriate number of tests and number of bulls to be tested.
