Abstract:

This study was conducted to compare the contents of amino acids and fatty acids in the muscles of Nixi chickens and Wuliangshan Black-boned chickens.44 Nixi chickens and 44 Wuliangshan Black-boned chickens were chosen and breast muscle and leg muscle samples were collected to measure the content of 17 amino acids and 18 fatty acids. The results showed that the content of Glu in the muscle of the two kinds of chickens was the highest,followed by Asp and Lys, the lowest content was Cys. The essential amino acid (EAA) content and essential amino acid ratio (EAA/TAA) of Wuliangshan Black-boned chickens was extremely significantly higher than Nixi chickens (P < 0.01). However,the content of aromatic amino acids (especially Glu) was extremely significantly lower than Nixi chickens (P < 0.01). The fatty acids in the two kinds of chickens were mainly consisted of oleic acid, palmitic acid,linoleic acid,stearic acid and arachidonic acid,and the rest of the fatty acids were lower. The content of total fatty acid,polyunsaturated fatty acids, unsaturated fatty acid and essential fatty acid of Wuliangshan Black-boned chickens were extremely significantly higher than Nixi chickens (P < 0.01).
