(A) Herd shall mean all cattle
(genus
Bos), bison, including calves under
common ownership or supervision, whether geographically separated or not,
except steers and spayed heifers.
(B) Whole Herd Vaccination. Vaccination of
all female cattle except spayed heifers over eight (8) months of age with a

thirty (30) days after vaccine is administered. The test schedule shall be
consistent with the schedule used in non-vaccinated herds.
(C) Individual herd plans shall mean an
approved brucellosis control program of the herd under quarantine for the
purpose of eliminating brucellosis from the herd, preventing spread to other
herds and preventing reintroduction after the herd has become free of
brucellosis. The individual herd plan shall be developed by the herd owner, the
owner's veterinarian, if requested by the owner, and the district veterinarian.
The individual herd plan shall be reviewed by the state veterinarian or his/her
designated representative and must be adhered to in order to be eligible for
indemnity payments.

3. All contact/adjacent exposed

Contact/adjacent herds shall be tested within one hundred twenty (120) days
after the affected herd is released from quarantine.
4. Individual herd management plan
requirements shall be met except when a designated brucellosis epidemiologist

expense to the owner, however, owners are to provide for handling of their
cattle.
