The nutritional quality of meat from pigs of the indigenous Prestice Black-Pied pig (PB) and the three-breed commercial hybrid of Large White × Landrace × Large White_sireline (CH) was compared using these indicators: content of intramuscular fat, protein, saturated fatty acids (SFA) and essential amino acids (EAAs). The protein content and energy value of PB and CH meat were 20.12% and 22.56%, and 426.77 kJ·(100 g)^–1 and 443.01 kJ·(100 g)^–1, respectively. The lowest fat content (1.33%) and SFA content (0.33%) were found in the meat of commercial hybrid pigs. Leucine and lysine were the most predominant EAAs detected. Valine and leucine are the limiting AAs in studied meat as a protein source for children at 0.5–2 years of age. The compositions of AAs in PB and CH pork fully meet the protein needs of children over 2 years of age and adults. The calculated amount of pork meat provides the required daily intake of AAs and ensures 5–8% energy for children and 8–11% energy for adults at moderate physical activity. In general, the meat of Prestice Black-Pied pig and of the commercial hybrid showed the high nutritional value and quality and it can be recommended for consumption in the diet by children and adults.
