The article is a review of literature and recommendation from weaned piglet nutrition problematics – how piglets are nourished in this critical period.This is a critical period in a piglet’s life, as it imposes not only a nutritional stress, but also a social stress induced by separation from the sow, a change of environment and a change of social hierarchy in the newly established groups of animals. After weaning, the feed ration changes, frequently bringing about changes in the piglet’s digestive tract, digestive disorders and diarrhoea. After weaning, piglets may experience temporary anorexia, stop eating or become more prone to intestinal infections. In addition, weaning also causes a change in the intestinal flora. If piglets are to enter rearing in optimal health condition, two basic tasks must be addressed: providing feed intake and avoiding piglet diarrhoea.
