Edwin Lauprecht

Edwin Karl Heinrich Lauprecht (born September 7, 1897 in Bremen , † July 7, 1987 in Göttingen ) was an important German animal breeding scientist.

Live and act

As the son of a pharmacy owner and later a farmer, he was taught at grammar schools in Bremen and Jever , took part in the First World War, then worked in his father's farms and studied agriculture at the University of Göttingen from 1919 to 1920 . This was followed by two practical years at Klostergut Beuren and as a milk control officer in the Jeverland Herdbook Association. In 1922 he still passed the Abitur examination. He then continued his studies in Göttingen and graduated in 1923 as a qualified farmer. In 1925 he became an assistant, later a senior assistant at the Institute for Animal Breeding and Dairy Management in Göttingen. Here he received his doctorate (according to the certificate) in 1927 with a zootechnical subject at the Faculty of Mathematics and Natural Sciences, to which all agricultural institutes belonged from 1922, for Dr. phil. (This title was still valid because of earlier membership in the Philosophical Faculty). The focus of his scientific work under Prof. Jonas Schmidt was investigations into the inheritance of colors and shape features in farm animals as well as crossbreeding experiments in pigs with comparisons of the performance between F1 animals and their parents. He also worked in the head office of the German Society for Zuchtungskunde (DGfZ), which was located in Göttingen at the time, and began editing two specialist magazines.

In 1930, Lauprecht completed his habilitation in Göttingen with a topic on Trakehner horses for the subject of agricultural animal breeding , then became a private lecturer, in 1936 an extraordinary (non-civil servant) extraordinary professor and from 1939 (civil servant) an extraordinary professor for this area. He now also dealt with questions of feeding and keeping farm animals. From 1939 to 1941 Lauprecht did military service as a clerk for animal breeding in Belgium and northern France . Afterwards, at his own request, he switched to the Kaiser Wilhelm Institute (KWI) for Animal Breeding Research in Dummerstorf near Rostock, where he became head of the cattle breeding department and arranged for crossings between Jersey and German Lowland cattle to control the inheritance of the amount and ingredients in cow's milk examine. At the University of Rostock, he also held lectures on general animal breeding and cattle breeding as an adjunct professor of animal breeding at the Faculty of Agriculture .

After the end of the Second World War and the threatened occupation of Mecklenburg by the Red Army, the Dummerstorf cattle herd was relocated to Lower Saxony. Lauprecht set up - together with Jonas Schmidt and then alone as acting head - in Mariensee near Neustadt am Rübenberge a new test farm as a West German successor to the KW Institute for Animal Breeding Research, which in 1948 became part of the Max Planck Society as the Institute for Animal Breeding and Animal Nutrition Mariensee / Trenthorst received (head: Prof. Max Witt ). Mariensee is now part of the Friedrich Loeffler Institute . Lauprecht was now head of the animal breeding and pet genetics department. Until 1967 he dealt with the influence of environmental factors on the performance characteristics of farm animals as well as with the relationships between various useful performances and their proportions of heredity. He was significantly involved in the development of new genetic-statistical methods for more precise breeding value estimation and had a separate department for population genetic evaluations set up at the Institute for Animal Breeding in Göttingen. In addition, as early as 1957, he developed a method for using special echo sounders (ultrasound from non-destructive material testing) to measure fat and muscle thickness - a method that is still used today as a performance test for estimating the meat content of live pigs before they are used for breeding and thus for Selection is used.

After retiring, Lauprecht moved back to Göttingen and died there at the age of 90.

Appreciation

With his investigations and results, Lauprecht has created scientific forerunner in the fields of applied population genetics in breeding and performance testing of farm animals. He was able to convincingly explain difficult genetic relationships to breeders and thus contribute significantly to the transfer of new knowledge into zootechnical practice. He promoted the fruitful cooperation between science and practice within the framework of the advisory board of the German Society for Zuchtungskunde (DGfZ), was editor for 20 years and then on the editorial committee of the specialist journal Züchtungskunde as well as co-editor of the yearbooks for scientific and practical animal breeding including breeding biology . From 1962 he headed the committee for genetic-statistical methods in animal breeding within the DGfZ and actively worked as a German delegate in the commissions for domestic animal genetics and for pig production of the European Association for Animal Breeding (EVT). Lauprecht was one of the most important German animal breeding scientists of his generation.
