The College of Veterinary Medicine was renamed the Center for Veterinary Health Sciences with the approval of the OSU Board of Regents in September 2004 to indicate that its work and services are much broader than a college alone. The center includes the Oklahoma Animal Disease Diagnostic Laboratory, the Boren Veterinary Medical Teaching Hospital and the College of Veterinary Medicine. In addition to advanced services in clinical and diagnostic programs provided by the laboratory, the center's research extends to biomedical science and comparative medicine.
