[Nutrition of young piglets in relation to weaning problems].

Weaning at the age of 3-4 weeks has great consequences for piglets. The consequences of the change from milk to solid food are discussed with regard to the supply of nutrients, the available enzyme capacity of the digestive tract, and the morphological and functional changes in the gut. A number of preventive measures are discussed, with a distinction being made between general measures, measures related to the composition of the diet, and measures related to specific additives. Future research should clarify the mechanism of action of specific additives and pay more attention to the uptake of nutrients in piglets in the period just after weaning.
