Evaluation of differences in the quality of pork meat from Czech pig breeds based on nutritional value, energy value and amino acid score

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 ofintramuscular fat, protein, saturated fatty acids (SFA) and essential amino acids (EAAs). The protein content and energy value ofPB 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 inthe meat ofcommercial hybrid pigs. Leucine and lysine were the most predominant EAAs detected. Valine and leucine are the limiting AAs instudied meat asaprotein source for children at0.5–2years 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.
