On a pig farm in Thuringia (Germany), data from 775 sows of 5 different genetic constructions were recorded from birth until exit. Based on live weight gain and lateral back fat thickness measured at selection (around 180th living day), statistical relations were analyzed in regard to the influence of both factors on reproduction performance. There are no uniform results in regard to their influence, from our investigations nor in literature references. Different races, stable systems, methods and equipment of measurement cause partly opposite statements about the influence of live weight gain and lateral back fat thickness on reproduction performances of sows. Based on these investigations an influence of genetic construction could be ascertained, because the stable system, equipment and method of measurement were uniform. As a result, a partly significant influence of genetic construction on living performance of sows could be verified.
