Organizational Unit
Veterinary Diagnostic and Production Animal Medicine
The mission of VDPAM is to educate current and future food animal veterinarians, population medicine scientists and stakeholders by increasing our understanding of issues that impact the health, productivity and well-being of food and fiber producing animals; developing innovative solutions for animal health and food safety; and providing the highest quality, most comprehensive clinical practice and diagnostic services. Our department is made up of highly trained specialists who span a wide range of veterinary disciplines and species interests. We have faculty of all ranks with expertise in diagnostics, medicine, surgery, pathology, microbiology, epidemiology, public health, and production medicine. Most have earned certification from specialty boards. Dozens of additional scientists and laboratory technicians support the research and service components of our department.
Organizational Unit
Veterinary Clinical Sciences
The mission of the Veterinary Clinical Sciences Department and the Veterinary Medical Center is to be strong academically, to provide outstanding services, and to conduct research in the multiple areas of Veterinary Clinical Sciences. Our goals are to teach students in the multiple disciplines of Veterinary Clinical Sciences, to provide excellent veterinary services to clients, and to generate and disseminate new knowledge in the areas of Veterinary Clinical Sciences. Our objectives are to provide a curriculum in the various aspects of Veterinary Clinical Sciences which ensures students acquire the skills and knowledge to be successful in their chosen careers. We also strive to maintain a caseload of sufficient size and diversity which insures a broad clinical experience for students, residents, and faculty. In addition, we aim to provide clinical veterinary services of the highest standards to animal owners and to referring veterinarians. And finally, we strive to provide an environment and opportunities which foster and encourage the generation and dissemination of new knowledge in many of the disciplines of Veterinary Clinical Sciences.

Traditional ovariectomy techniques for heifers (e.g. colpotomy) have adverse effects ranging from hemorrhage to mortality. Electrosurgical bipolar vessel sealing devices offer a superior ligation of ovarian pedicle and associated structures. In ruminants, standing flank laparotomy has been used for abdominal visibility. We performed ovariectomy in 2 companion beef heifers via a unilateral flank approach, combined with electrosurgical ligation. Surgeries were performed in standing animals, under local anesthesia, with no observed short- or long-term adverse effects. This technique is worth considering for cases where the security of electrosurgical ligation combined with the accessibility of a flank laparotomy are desired. Additional research is needed to determine the viability of the technique for cattle of various ages and breeds.
