(d) Pseudorabies vaccine shall be used only with approval of the state veterinarian.
(3) If official depopulation is the approved herd cleanup plan, the plan shall:
(a) Be recommended by an official epidemiologist, approved by the state veterinarian and agreed to by the herd owner; and
(b) Require the premises to be cleared of breeding swine within two (2) months of the date of approval and cleared of all swine within eight (8) months of the plan approval date.
(4) If test and slaughter is the approved herd cleanup plan, additional tests shall be performed until all positive animals in the herd are identified and slaughtered.
(5) The official herd cleanup plan shall provide for the completion of all requirements set out in the cleanup plan within twenty-four (24) months of the plan approval date. Except, the state veterinarian may approve additional time, not to exceed ninety (90) days, for completion of all requirements set out in the plan.
(6) The herd cleanup plan may be changed or amended if approved by the official pseudorabies epidemiologist and the state veterinarian.
(7) If the owner of a pseudorabies infected herd does not develop an official herd cleanup plan, if the state veterinarian determines that the official herd cleanup plan has not or will not effectively eliminate pseudorabies from a swine herd, or if that approval or continuation of the official herd cleanup plan is unlikely to effectively eliminate pseudorabies from the herd, the board or its authorized agents shall order depopulation as provided by KRS 257.110.

(2) Feeder pigs from qualified pseudorabies negative herds with a valid Certified Feeder Pig Producer Card (CFPP), or herds with a valid Pseudorabies Surveillance Card (PS) may be moved without individual identification from an originating Kentucky farm to another Kentucky farm for purposes of feeding for slaughter if all feeder pigs on the recipient farm are from the same originating herd. Approval of the State Veterinarian and compliance with requirements of 302 KAR 20:210 shall be required before swine may be moved.
(3) Swine originating from a state which qualifies for Stage IV or V under the national program standards may enter Kentucky without a test unless a test prior to entry for exhibition or sale is required by the state veterinarian because there has been a break in Stage IV or Stage V status or there has been an exposure to pseudorabies.
Section 6. Indemnity. (1) State indemnity funds, if available, shall be paid in the following amounts for swine sent directly to slaughter:
(a) Twenty-five (25) dollars per head for all seropositive breeding swine if test and slaughter, voluntary depopulation, or a herd plan other than official depopulation or mandatory depopulation is the herd cleanup plan.

(b) If test and slaughter was the official herd cleanup plan, the herd shall have two (2) negative tests. The first test shall be no less than thirty (30) days after the last positive animal has been sold to slaughter. The second test shall be more than sixty (60) days after the last positive animal is sold for slaughter. The second test shall include all breeding swine; all other swine on the premises shall be randomly sampled.
(2) Other quarantined herds shall not be released until after a negative test, as directed by the official pseudorabies epidemiologist, and quarantine release approved by the state veterinarian.
