Current through Register Vol. 35, No. 18, September 24, 2024
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.
