The experiments examined the effects of changes in feed composition and were carried out in pigs. The effects of - changes in crude protein content and in the ratio of essential amino acids, with a constant energy level, - different quantities of lysin, treonin, and tryptophan in feed with different crude protein content and constant energy level, - different energy levels of fedd, in the first part of the fattening period, - different energy levels of feed, combined with different crude protein and different quantities of lysin, treonin, and tryptophan in fodders in the second part of the fattening period were studied.
