[Importance of stable gastrointestinal microflora in growing animals]

A zysbiosis can be caused by food constituents. Food portions with 40% rye for chickens release a destabilisation of the gut flora. This can be prevented by effective stabilizers. Early weaned piglets harbour high numbers of E. coli in their ileum and jejunum content. These become decreased by about three tens powers by affective gut flora stabilizers. Simultaneously the body mass rises considerably without an increase of the food consumption with reference to the living mass. Partially, the ergotropic effect of the gut flora stabilizers is attributed to the smaller expense for the immune defence. Therefore, a new hypothesis for the growth stimulating effect of ergotropics for early weaned piglets is created.
