Okla. Admin. Code § 35:15-17-1
The following words or terms, when used in this Subchapter, shall have the following meaning, unless the context clearly indicates otherwise:
"Affected herd" means a herd of cattle that has had a brucellosis reactor disclosed from an on-farm test or is the herd of origin of a market cattle identification brucellosis reactor from which a field strain Brucella abortus bio-variety has been isolated.
"Animals" means all bovine, dairy and beef breeds, and bison.
"Approved brucella vaccine" means a product that is approved by and produced under license of the United States Department of Agriculture for injection into cattle or bison to enhance their resistance to brucellosis.
"Cattle" means bison, dairy, and beef animals.
"Commuter herd" means all cattle under common ownership or supervision, that are located on one (1) or more premises in two (2) or more states and there is an interchange or interstate movement of animals between premises in those states as part of the normal farming, breeding or ranching operation without a change of ownership. A commuter herd agreement shall be completed and approval of commuter herd status shall be obtained from each chief animal health official of all states in which the herd resides.
"Domestic livestock" means those species of animals that have adapted to life in intimate association with, and provide advantage to man for use as food, fiber (furs and leather), labor and companionship. This adaptation usually involves the modification of growth or other traits through the provision of food, protection from enemies and selective breeding, thereby reducing the ability of that species to survive in the wild.
"Exposed animals" means animals that are part of a known affected herd or have been in contact with brucellosis reactors in marketing channels for periods of twenty-four (24) hours or periods of less than twenty-four (24) hours if the reactor has recently aborted, calved, or has a vaginal or uterine discharge. These animals are considered to be exposed regardless of the blood test results, and shall be placed under quarantine and restricted pending slaughter or testing after return to the herd of origin. These animals shall be identified with a hot iron letter "S" brand on the tailhead at least 2x2 inches prior to movement from the premise.
"Farm of origin" means a farm or other premises where the cattle to be shipped were born or have been kept for not less than four (4) months prior to the date of shipment and the premises within the four (4) months prior to the date of shipment have not been used to assemble cattle from any other premises.
"Feedlot" means a confined drylot area for finish feeding of animals on concentrated feed with no facilities for pasturing or grazing. The feedlot may not hold any test eligible animals of unknown status or "S" branded animals.
"Herd" means all cattle (genus Bos) and bison (genus Bison bison) under common ownership or supervision, that are grouped on one or more parts of any single premise (lot, farm, or ranch) or on two (2) or more premises geographically separated, but have had an interchange movement or contact. Contact shall be accepted as fact unless otherwise established by the owner and consistent with the findings of the epidemiologic investigation. Groups of animals under multiple ownership on common premises, such as community pastures, grazing association allotments, etc., shall also be considered as a herd. For brucellosis eradication purposes the herds shall include all other groups of animals owned by those persons unless the veterinary medical officer, based on an epidemiologic investigation, establishes that association has not occurred.
"Herd test" means a test that includes all animals over six (6) months of age except steers and spayed heifers. Breeding animals tested shall be identified with official identification.
"Individual herd plan" means a herd management and testing plan designed by the herd owner and a veterinarian of the Cooperative Brucellosis Eradication Program that will control and eradicate brucellosis from an affected herd and shall include a similar plan for determining the true status of suspects and preventing exposure to brucellosis within the herd.
"Official test" means any serologic or bacteriologic test recognized by and listed in the USDA Uniform Methods and Rules of Brucellosis Eradication or the Code of Federal Regulations. The official test sample shall be collected by an accredited veterinarian or an employee of the State-Federal Brucellosis Program. The test shall be conducted in an official State-Federal Brucellosis Laboratory or licensed and approved Auction Market Laboratory, or by an employee of the State-Federal Brucellosis Program in field situations. All tests shall be confirmed in an official State-Federal Brucellosis Laboratory.
"Official vaccinate" means a female bovine or bison animal vaccinated against brucellosis with an approved brucella vaccine between four (4) and twelve (12) months of age. All vaccination shall be conducted under the supervision of a federal or state veterinary official or accredited veterinarian. Vaccinated animals shall be permanently identified as vaccinates and reported at the time of vaccination to the appropriate state or federal agency cooperating in the eradication of brucellosis.
"Permit" means an official document (USDA VS Form 1-27 or comparable State Form) that is required to accompany "B" branded cattle, "S" branded cattle, and exposed cattle moved under official seal, issued by a veterinary services representative, state representative or accredited veterinarian that lists the official identification, USDA backtag, registration number, reactor tag number, owner's name and address, origin and destination, number of animals covered, and the purpose of the movement. If a change in destination becomes necessary a new permit shall be prepared. No diversion from the permitted destination is allowed. Copies of the permit shall be distributed in accordance with the instructions printed on the official document.
"Permit for entry" means a premovement authorization for entry of cattle into a state from the animal health official in that state. The authorization shall state the conditions under which movement may be made, and these conditions may be in addition to the requirements of the USDA Uniform Methods and Rules for Brucellosis Eradication (UM&R) and Code of Federal Regulations.
"Rodeo bulls" means sexually intact male cattle kept for the purposes of performances at rodeos, for exhibition purposes or for breeding to produce rodeo bulls, and shall include bulls changing ownership.
"S brand" means identification of animals by branding with a hot iron the "S" that is at least 2x2 inches and placed on the tailhead. "S" branding is required for suspect animals and movement of exposed animals from affected herds.
