Hanford Miniature Swine


    • Hanford Labs started developing the Hanford miniature swine in 1958 in Richland, WA with two Palouse gilts and one Pittman-Moore boar; later addition of more Pittman-Moore and Swamp hog from Louisiana further reduced the size.
    • Selection occurred at 140 days of age for fitness, skin and hair color, conformation, thickness of hair coat, and demeanor.
    • Battelle Memorial Institute acquired the herd in the mid-1960’s and introduced Yucatan into the foundation stock.
    • Charles River Laboratories assumed the breeding of the Hanford in 1982 at Wilmington, MA.
    • The colony was moved to Pittsfield, NH in 1983.
    • Sinclair BioResources acquired the Hanford herd in 2002 and moved the colony to Columbia, MO.
    • The colony is closed and fully-pedigreed


    • Well-adapted to the laboratory environment
    • Looks like traditional farm pigs
    • Used predominantly as a dermal toxicology model
    • White skin and haircoat make them excellent for dermal studies
    • Lack of fat makes them a good model for surgical studies
    • Heart size and collateral blood flow very similar to human hearts makes them an excellent cardiovascular mode
