The addition of lysine, methionine and threonine to the "ideal protein" diet in the low-protein diet contributed to increased protein deposition in the body of piglets due to protein-synthesizing activity. The optimal level and ratio of essential amino acids in low-protein diets provides an increase in the efficiency of the use of amino acids for the synthesis and deposition of proteins in the body of piglets. Based on the results of assessing the metabolism of proteins in the body and their turnover in piglets (♂ Landrace × ♀ Large white) during the period of intensive rearing from 20 to 50 kg of live weight at an average daily gain of 500 g, the following norms for the concentration of nutrients in 1 kg of compound feed are proposed: 12.42 MJ exchange energy; 120.6 g crude protein; 9.10 g lysine; 5.90 g methionine + cystine; 6.09 g threonine at a lysine level of 0.73 g per MJ of metabolizable energy.
