If the method of appraisal prescribed by § 47-13-380 is unsatisfactory to the owner, within twenty-four hours after receipt of notice from the State Veterinarian, the owner may file with the State Livestock-Poultry Health Commission a protest stating under oath, to the best of his knowledge and belief, the animal is not infected with tuberculosis or glanders. If the animal is killed an autopsy must be held by three experts who must be graduate veterinarians of a recognized college. One must be appointed and paid by the owner, one must be appointed by the State Veterinarian and paid by the State, and one must be the State Veterinarian or his assistant. These three experts shall appraise the animal before it is killed at its actual cash value, and if the autopsy shows the animal is free entirely from the disease, the cash value of the animal immediately before the killing must be paid to the owner by the State, less the value of the carcass.
