N.J. Stat. § 4:5-10
When animals are slaughtered or otherwise disposed of as directed in section 4:5-9 of this Title, the value of the same may, at the request of the department or any person interested, be ascertained and appraised by any authorized agent of the department, or in cases where an agreement between the agent and the owner cannot be reached, by three disinterested freeholders resident in this State, one chosen by the agent, one chosen by the owner and the third by the first two at the expense of the owner, who shall make and sign a certificate thereof in the presence of a witness who shall attest the same.
The appraisement shall be made on the basis of the market value of the animals to be slaughtered immediately prior to the time of the discovery of the infection.
Such appraisal and disposal shall be carried out under such rules and regulations as may be prescribed by the board, which may prescribe a maximum payment for any animal or animals, and may authorize the condemnation of an entire herd of animals and compensation therefor, even though all of the animals in the herd are not infected, where the secretary determines that an entire herd or flock needs to be slaughtered to control a disease or prevent its spread to other animals. The total amount receivable by the owner from the net proceeds of the sale of the animal, plus indemnity, if any, from the Federal Government, and plus the indemnity from the State, shall not, however, exceed the appraised value of the animal or animals. The board may promulgate rules and regulations to authorize payment for any disposal cost determined to be necessary.
