Aged Rodent Colonies Handbook

Optional Services

NIA rodents are tattooed on the tail with the month and year of birth. Aged animals are often more sensitive to the stress of anesthesia and surgery and it is not unusual for some mortality during or directly after surgery. When surgical procedures are requested on animals from the NIA aged rodent colonies, the customer is responsible for the cost of the surgery directly to the contractor performing the services, regardless of the outcome. The order must include a PO or credit card for the Contractor to bill for the optional services.

Charles River Laboratories (CRL) implants AVID Microchips as an independent service, at a total cost of $21.90 per animal. Surgical procedures are also provided by CRL as independent services and prices are on pages 32 and 33 of the CRL Research Models & Services catalog.
