Large Animal Regulatory Services in Crescent, OK
Moving livestock, selling animals, or meeting herd health requirements often means more than routine veterinary care. At HF Veterinary Services and Boarding Kennel, we provide USDA-accredited large animal regulatory services for cattle, horses, pigs, sheep, goats, llamas, and alpacas in Crescent, OK, and surrounding communities. We help commercial producers and hobby farms stay compliant with state and federal regulations while providing excellent care at a reasonable price.

Helping You Meet Regulatory Requirements
Regulatory veterinary services protect animal health and support the safe movement of livestock. Whether you’re transporting animals across state lines, preparing for a livestock sale, attending a show, or managing a food production operation, the right testing and documentation matter.
With more than thirty years of experience serving Oklahoma’s rural communities, our family-focused, mixed-animal practice works with producers, ranchers, and hobby farmers throughout Crescent, Guthrie, Kingfisher, Cashion, Hennessey, Edmond, and nearby areas. We explain requirements in plain language so you know exactly what your animals need.

Health Certificates (Certificates of Veterinary Inspection)
A Certificate of Veterinary Inspection (CVI), also called a health certificate, confirms that an accredited veterinarian has examined your animal and that it meets travel requirements.
Health certificates are commonly required for:
During your appointment, we’ll perform a physical examination, verify identification, and complete the required paperwork. Since regulations vary by state, scheduling ahead helps avoid delays.
Veterinary Feed Directives (VFD)
A Veterinary Feed Directive (VFD) is written authorization that allows certain medicated feeds to be used legally in food-producing animals.
If your cattle, pigs, sheep, or goats require medicated feed, we’ll determine whether a VFD is appropriate, explain current regulations, and provide the documentation you need. We also answer questions about recordkeeping and maintaining a valid veterinarian-client-patient relationship (VCPR).
Coggins Testing (Equine Infectious Anemia Testing)
Equine Infectious Anemia (EIA) is a contagious viral disease of horses. A Coggins test is the official blood test used to detect the disease.
Many boarding facilities, horse shows, sales, and interstate travel require a current negative Coggins test. We’ll collect the blood sample, submit it to an approved laboratory, and provide the official results as soon as they’re available.
Bang's Vaccination (Brucellosis Vaccination)
Bang’s vaccination protects eligible cattle against brucellosis, a disease that can affect livestock health and herd management.
As a USDA-accredited veterinarian, Dr. Hufnagel provides official calfhood brucellosis vaccinations, proper animal identification, and the required documentation to help producers meet state and federal regulations.
Official Calfhood Vaccination Program
The Official Calfhood Vaccination Program helps protect young cattle while supporting disease control efforts across the livestock industry.
Eligible calves receive the official vaccination, identification, and permanent records required through the USDA program. If you’re unsure whether your animals qualify, our team can help you determine the best timing for vaccination.
