To evaluate the nutritional value of Fengjing pigs (FJ) and their F1 hybrid generation, FJ, Duroc (American)×Fengjing pigs (DAF), Duroc (Norwegian)×Fengjing pigs (DNF), Pietrain×Fengjing pigs (PF) and Duroc×Landrace×Yorkshire pigs (DLY) were studied. After analyzing the amino acid and fatty acid nutritional indices, their nutritional values were thoroughly evaluated using principal component analysis. The results showed that the Σn-3polyunsaturated fatty acids were significantly higher in FJ and its hybrid combinations than in DLY, and the essential amino acid index (EAAI) was relatively high (86.32~90.66). Containing abundant characteristic amino acids, FJ exhibited the highest intramuscular fat content (4.77%), ΣPUFA (17.05%), and healthy fatty index (1.83). Among the different hybrid combinations, DNF had the highest characteristic amino acids content whereas DAF had the lowest atherogenic index (0.54) and thrombogenic index (1.31). PF exhibited the highest EAAI (90.66), nutritional index (20.63), and biological value (87.12), despite containing the least characteristic amino acids. Valine was identified as the first limiting amino acid of all five groups of pork samples. The order of comprehensive nutritional value score was: PF>DNF>FJ>DAF>DLY. In conclusion, FJ and its hybrid combinations are high-quality ingredients for PUFA intake, containing nutritious fatty acids and proteins, whereas PF is the hybrid combination with the highest comprehensive nutritional value.
