The Göttingen Minipig is a member of the species Sus scrofa domestica along with other domesticated swine.  The Göttingen Minipig is best known for its exceptionally small size and its very clean and well-characterized health status.  Development of this breed began in the late 1960s at the Institute of Animal Breeding and Genetics (Institut fϋr Tierzucht und Haustiergenetik) at the University of Göttingen, Germany, by crossbreeding the Minnesota minipig, the Vietnamese Potbelly Pig and the German Landrace pig.  Today the Göttingen Minipig is bred at four separate locations globally and is used in life-saving biomedical research all over the world.
