Current through Reg. 50, No. 187; September 24, 2024
If infection is disclosed in swine herds, one of the
following plans shall be selected for eradicating the disease and for
subsequently qualifying the herd for Validated Brucellosis-Free status, if
desired. Infected herds under test for area validation status shall also choose
one of these plans to eradicate brucellosis from the herd.
(1) Plan 1: Infected commercial herds.
(a) The entire herd shall be disposed of for
slaughter as soon as practicable.
(b) All buildings and equipment and as much
of the hog lots as possible shall be thoroughly cleaned and
disinfected.
(c) Replace with stock
from validated or negative herds, if possible, placing them on clean ground
that has been free of swine for at least 30 days.
(2) Plan 2: Infected purebred herds desiring
to retain valuable blood lines.
(a) Separate
pigs from sows at 28 days of age or younger, and isolate.
(b) Market infected herd for slaughter as
soon as practicable. Infected sows shall not be rebred and shall be slaughtered
as soon as possible. Complete isolation of infected animals is required. The
separated weanling pigs form the nucleus for establishment of the
brucellosis-free herd.
(c) Test
gilts to be used for the following season about 30 days before breeding. Save
only gilts which are negative and breed these only to negative boars.
(d) Retest gilts after farrowing and before
moving them from the individual farrowing pens or crates. Should reactors be
found, they should be segregated from the remainder of the herd and slaughtered
as soon as possible. Only pigs from negative sows should be selected for
breeding gilts.
(e) Repeat this
process until the herd is negative. The herd is eligible for release from
quarantine upon passing three consecutive negative tests 60 to 90 days apart,
with the first test not less than 30 days after removal of the last
reactor.
(3) Plan 3:
Herds with light infection (only a few reactors and where no clinical signs of
brucellosis have been noted).
(a) Remove
reactors for slaughter.
(b) Retest
the herds at 30-day intervals, removing reactors for slaughter until entire
herd is negative.
(c) This plan
shall be abandoned if the herd is not readily freed of infection.
(d) A herd is eligible for quarantine release
upon passing three consecutive negative tests 60 days
apart.
