Current through Register Vol. 35, No. 18, September 24, 2024
A.
Commingled grazing. All non-virgin bulls commingling in grazing
associations or multiple permittee allotments or leases, shall have the
official T. foetus bull test conducted annually prior to turn
out. A new official test will be required each time the bull(s) enter a
different grazing association or multiple permittee allotment or lease. If a
bull is found positive, the entire bull population present on the allotment or
lease, regardless of ownership, will be required to have an official T.
foetus test conducted. All positive bulls shall be identified with the
official New Mexico livestock board "N" fire brand or NMLB approved method, and
be sold for slaughter only. All test negative bulls belonging to the same
owner(s) will be required to have a second negative test prior to turn out and
a third negative official test after the bull(s) are removed from the grazing
association or multiple permittee allotment or lease.
B.
Positive T.
foetus
bull & herd. Any confirmed T.
foetus bovine and its herd (as defined by state animal health
officials) shall immediately be placed under quarantine and will continue under
quarantine until the following rules are completed.
(1) Positive T. foetus bulls
shall be identified with the official New Mexico livestock board "N" fire brand
or other NMLB approved method.
(2)
Positive T. foetus bulls shall be quarantined and sent
directly to slaughter or to public livestock market for slaughter only.
Positive bulls may be required to move on a NMLB approved method. Confined
feeding may be allowed provided bulls are "N" branded.
(3) All other bulls in a positive T.
foetus herd shall test negative to three consecutive official
T. foetus tests at least seven days apart. The third
T. foetus test will be completed within 12 months of
T. foetus confirmation in the herd and will be conducted after
the bulls have had breeding exposure to the cow herd for a minimum of 65
consecutive days. A shorter breeding season must be approved by the state
veterinarian, and be provided for in the herd management plan. The bulls will
be removed from the cow herd at least seven days prior to the official
T. foetus test. If more than 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.
(4) If a disease
management plan has not been developed and activated within 45 days of
confirmation of T. foetus infection in the herd, all bovids,
except steers and spayed heifers, will be required to go directly to slaughter
upon leaving the ranch.
(5) Any
bull entering a quarantined premise will be required to test negative prior to
re-introduction to its herd of origin.
C.
Reproductive bovine females from a
positive T. foetus herd.
(1) Females over 12 months of age (not known
to be virgin heifers) from a positive T. foetus herd may be
sold direct to slaughter or quarantined on the premises of origin. Individual
females may be released from quarantine when either all requirements of
Paragraph 3 of Subsection B of 21.30.6.11 NMAC have been met or the cow(s) has
a calf at side with no exposure to other than known negative T.
foetus bulls since parturition, has documented 120 days of sexual
isolation or is determined by an accredited veterinarian to be at least 120
days pregnant. Heifers known to be virgin at the time of turnout or heifers
exposed only to known negative T. foetus bulls and not yet 120
days pregnant are allowed unrestricted movement.
(2) Open females shall be sold to slaughter
or held in isolation from all bulls for 120 days. Any female sold to slaughter
through a livestock market shall be identified with an official New Mexico
positive T. foetus tag or NMLB approved method during the
quarantine period.
(3) Breeding by
artificial insemination is allowed during the quarantine period and cows
confirmed by an accredited veterinarian to be at least 120 days pregnant as
well as cows documented to have 120 days sexual isolation will be released from
quarantine.
(4) If a disease
management plan has not been developed and activated within 45 days of
confirmation of T. foetus infection in the herd, all bovids,
except steers and spayed heifers, will be required to go directly to slaughter
upon leaving the ranch.
D.
Regulatory action.
(1) Any stray non-virgin bull of unknown
T. foetus status, or from a positive T.
foetus herd, that enters the land of a neighboring premise, and may
have commingled with the herd on that premise, will be quarantined until the
bull(s) has one or more official T. foetus test(s) conducted.
A NMLB livestock inspector shall be involved in the interaction.
(2) The test(s) shall be the responsibility
of the bull(s) owner. The conditions of the quarantine and the number of tests
will be determined by the state veterinarian.
E.
Neighboring facilities of a positive
T. foetus herd.
(1)
All facilities that share a common boundary with a positive T.
foetus herd will be notified by the NMLB and will be required to test,
due to the fact that T. foetus is a regional disease, and all
neighbors testing will facilitate a more rapid regional eradication. Certified
New Mexico T. foetus free herds in compliance with the
provisions of
21.30.6.10
NMAC, will be exempt from testing, as well as instances where the state
veterinarian has determined such testing to be unnecessary based on
epidemiological investigation. This requirement will be reevaluated by the
working Trichomoniasis committee every two years.
(2) Any exposed herds found positive upon
testing will be designated as a positive T. foetus
herd.
