Farm-type procedures may be performed at the agricultural center. Surgical procedures on wild animals, both major and minor may be performed in the field but aseptic principles must be followed. Cost savings is not an acceptable justification for multiple major survival surgeries on any animal. If such impairment develops after a surgery, that animal cannot be used for another recovery procedure. If the second major procedure is non-survival, this is not considered to be multiple major survival surgery.
Examples are laparoscopy, superficial vascular cutdown, and percutaneous biopsy.
A dedicated surgical facility is not required for such procedures, however, the surgical area should be clean and aseptic techniques must be observed. For minor survival surgery procedures, there is no prohibition against multiple procedures. Good professional judgment should be used to limit the number of minor surgical procedures performed on a single animal. It is often not possible to have a fresh pack of sterile instruments available for repetitive rodent surgeries. Thus, resterilization or decontamination procedures must be available.
