Strain description
- Animals are docile.
- Females are good foster mothers.
- Mammary tumours are common in older females.
- Popular rat to function as foster parents in caesarean procedures.

- Originated in 1925 by Robert W. Dawley from a hybrid hooded male and a female Wistar rat. To Charles River in 1950 from Sprague Dawley, Inc.
- Charles River Breeding Laboratories obtained the stock after CRL had re- established an International Genetic Standard colony.
- Received as CD stock from Charles River Breeding Laboratories, (April 1999) as SPF stock. Passed directly into the SPF barrier after quarantine in flexible film isolator to verify SPF status.
- Stock strain is transferred to Ozgene ARC from Animal Resource Centre (ARC), Western Australia in 2023.
- Animal is a multipurpose model that can be used in fields such as toxicology (safety and efficacy testing), aging and oncology.
