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

Popis výsledku v původním jazyce

The nutritional quality of meat from pigs of the indigenous Prestice Black-Pied pig (PB) and the three-breed commercial hybrid of Large White x Landrace x Large Whitesireline (CH) was compared using these indicators: contentof 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.
