Nutritional problems of every category of pigs are presented in this paper. Nutrition of pigs is in constant changes adapting to the improvements of genetics potential as well as to the very severe ecological demands. As far as piglets just weaned are concerned, the nutrition problem is solved by means of adequate mixture with additives so that performance at this stage is remarkably increased. Nutritional problems of pregnant and lactating sows are analyzed. In pregnancy it is attempted to involve in practice cheap mixtures low in concentration of nutrients, while the needs of lactating animals are constantly increasing. As for fattening animals, a significant improvement is expected in the period to come if a multiphase feeding system is applied. At the same time such a system gives an opportunity to use rationally liquid by-products of the food processing industry with the maximum adaptive possibilities to the needs of pigs.
