The Gottening Research pig

The Gottening Research pig, known in the USA linked to The Juliani.2. Population history The Göttingen Minipig is a relatively young composite breed. Its development started in the 1960’s through an initiative of Prof. Fritz Haring and his co-workers (especially Prof. Ruth Gruhn and later Prof. Peter Glodek) at the former Institute of Animal Breeding and Genetics
of the Georg-August University Göttingen, Germany. The development of the breed was inspired by the existence of similar miniature breeds, like the Minnesota Minipig, in the United states, and from the beginning aimed at developing an experimental model animal for medical and pharmacological research. The development of the breed started in 1960 with an import of three male and two female Minnesota Minipigs from the Hormel Institute in Austin, Minnesota (USA).
The Minnesota Minipig itself is a composite breed which was developed at the Mayo-Clinic in Rochester, Minnesota by Professor Winters from the Hormel Institute in Austin, Minnesota. The development was started in 1949, based on black Guinea hogs from Alabama, feral boars from the Pacific island of Catalina, and PineyWoods “rooters” from Louisiana. In 1957 animals of the Ras-n-Lansa breed from the  island of Guam, with strongly expressed dwarfism, were introduced to reduce size (Beglinger, Becker, Eggenberger, & Lombard, 1975). It is
interesting to note that two out of four founder breeds of the Minnesota Minipig are island-based strains, making use of the evolutionary phenomenon of so-called island dwarfism, reflecting the observation  Journal of Pharmacological and Toxicological Methods 62 (2010) 221–226 ☆ The opinions expressed in this paper are those of the authors and not necessarily

The Minnesota Minipigs were reciprocally bred with three male and four female Vietnamese potbelly pigs from the Wilhelma Zoo in Stuttgart, Germany. The resulting population was spotted and phenotypically strongly affected by the (undesired) characteristics of the potbelly pigs. To widen the genetic basis four additional Vietnamese female potbelly pigs were imported in 1965 from the Friedrichsfelder Zoo in East Berlin, leading to a smaller and less coloured pig (Glodek & Oldigs, 1981).
It was soon realised that for many applications, especially in dermatology and growth/muscle studies, a leaner (less potbelly-type) pig with white skin would be desirable. For this purpose, genetics of commercial German Landrace pigs were introduced by artificial insemination during the years 1965 to 1969. At that time, separate lines of coloured and white minipigs were established. Glodek and Oldigs (1981) reported that the proportional representation of the three original breeds in the white line 1969 was 60% Vietnamese
potbelly pigs, 33% Minnesota Minipigs and 7% German Landrace.

The link to the Juliani where the first colored pigs produced and some where introduced to the pet trade, Later on they decided to introduced the white gene of the german Landrace resulting in the white Gottenings used today for lab research.
