Abstract: In present experiment,meat quality was analysed for randomly selected 120 day-old 10 chickens(♀:5,♂:5) from the same grazing conditions of Sizhou chicken and to provide scientific information for its exploitation. The results indicated that Sizhou chicken had excellent muscle tenderness,high dry matter,rich calcium,lower selenium and iron,moderate zinc. Oleic acid,linoleic acid,palmitic acid and stearic acid accounted for 92.20% in all of 11 fatty acids in chest muscle. Unsaturated fatty acids and essential fatty acids was 69.35% and 15.31%,respectively. Glutamic acid,aspartic acid,lysine and leucine accounted for 44.22% in all amino acids. Essential amino acids,palatable amino acids,sweet amino acids,aromatic amino acids,branched chain amino acids and antioxidant amino acid contents were 39.40%,26.18%,20.09%,7.06%,18.08% and 11.61%,respectively. Therefore,Sizhou chicken had excellent meat quality and good flavour.

Key words: Sizhou chicken; meat quality; mineral matter; fatty acid; amino acids
