Cattlemen’s Congress Livestock Health Requirements


Please share this information with the accredited veterinarian issuing paperwork. If you have questions concerning Certificates of Veterinary Inspection or official identification, please contact the State Veterinarian’s Office.


  1. Certificate of Veterinary Inspection:

An official CVI issued within thirty (30) days prior to the Cattlemen’s Congress must accompany all animals and shall be available at all times to the representatives of the Animal Industry Services of the Oklahoma Department of Agriculture. ALL LIVESTOCK MUST BE ACCOMPANIED BY A CERTIFICATE OF VETERINARY INSPECTION (HEALTH CERTIFICATE), WHICH MUST BE CHECKED BEFORE UNLOADING. All CVIs must be validated (stamped) by Entry Gate Officials before animals are given stall or pen space in the barns. All animals must be free of any infectious, communicable, or contagious disease and if such a disease is found, it will be cause for removal of the animal(s) from the exhibition. For questions regarding CVI’s, official identification, or import requirements, please call Animal Industry Services at: 405-522-6141.

Cattlemen’s Congress will have a zero-tolerance policy on animals entering the facility with infectious, communicable, or contagious disease, which includes warts and ringworm. 


  1. Official Identification

All cattle moving interstate for exhibition or show events are required to have official individual identification ear tags present in the ear. To avoid potential problems, all U.S. cattle entering the show grounds will be expected to have a USDA Official ID ear tag present in the ear. This includes Oklahoma originating cattle. Official Identification must be listed on the CVI.

The following forms of identification are considered official:

  • RFID 840 or visual 840
  • Orange Metal Official, Calfhood Vaccinate (OCV/Bang’s) tag – if applied prior to November 4, 2024
  •  Silver Metal USDA tag – if applied prior to November 4, 2024


  •  For long eared cattle ONLY, such as Brahman, Santa Gertrudis, etc., a Registered Brand or Ear Tattoo are sufficient (copy of registration certificate with brand or tattoo listed is required to be displayed at entry)

Cattle without proper identification will not be allowed to enter the barns.  It shall be the responsibility of the exhibitor to find a veterinarian to apply official ID if it is not present upon arrival at the entry gate

Health Protection Guidelines

  1. Cattlemen’s Congress is dedicated to protecting the health and well-being of livestock on the premises. 
  2. If an animal becomes ill the owner/exhibitor should contact show officials immediately. 
  3. Any expenses incurred by the assistance of an on-site veterinarian shall be the sole responsibility of the owner of the animal. 
  4. Cattlemen’s Congress will not be held liable for deceased animals, the disposal of deceased animals, or animals which are humanely euthanized. In the unfortunate event of an animal perishing while on the fairgrounds or being humanely euthanized by a veterinarian, the owner (exhibitor) of the animal will be responsible for removing the animal from the facilities.
