Large Animal Resources Division of Animal Research and Training Core

The Department of Surgery’s Large Animal Resources Division of Animal Research and Training Core, led by Kyha Williams, DVM, provides expertise and support for large animal-based investigations and training. Services provided include performing and providing technical expertise for research and training related large animal procedures. The Core offers services to investigators within and outside of the Duke Department of Surgery. 

Currently, supported species include non-human primates (various species), cattle, sheep, swine, dogs, and rabbits. The Core also supports skills and techniques courses open to fellows, visiting scholars, residents, mid-level and laboratory personnel, medical students, faculty, and college students from Duke and outside institutions both nationally and internationally. The Core has access to six dedicated operating rooms, including one operating room designed with six tables to accommodate large teaching classes, through the Duke Department of Laboratory Animal Research (DLAR)’s Vivarium. The Core owns and maintains its own equipment, including anesthesia machines, monitoring devices, instruments, ultrasound, cardio bypass equipment, and more.
