The paper presents an overview on experiments concerning a nutrition especially adapted to the physiological preconditions of the intestinal tract of the pig. The following aspects should be pointed out: 1) the pig is a selectively eating animal with enamelled teeth not suitable for intensive grinding but preferentially for squeezing. So pigs need a grinded diet of sufficient energy concentration. But a certain limit of crude fibre improves saliva production and the barrier function of the stomach; 2) an effective pH-decline is the basis of digestion in the stomach. This can be improved by a certain fibre content in the diet; 3) together with sufficient grinding, a restrictive feeding and a minimum hygienic quality helps to prevent microbial digestive disorders; 4) the integrity of the mucosa of the small intestine, its physiological development afterbirth and following the weaning process should be taken into account; 5) a high digestibility, the central role of essential nutrients for differentiation of the gut, the process of adaptation just after weaning should be taken into consideration; 6) it is shown that high digestibility in the small intestine together with a certain level of crude fibre improves the buffering capacity of ileal digesta flowing to the colon. This strategy helps to prevent the development of dysfermentations and the risk of colonic acidosis.
