Composition of fatty acids in the muscle of black-bone silky chicken (Gallus gellus demesticus brissen) and its bioactivity in mice

Total lipid (TL), phospholipids (PLs) and composition of fatty acids were determined in the muscle of black-bone silky chicken (BSC) and two other common chicken breeds, Lingnan Yellow Chicken (LNYC) and Chongren Chicken (CRC). The lowest content of TL and the highest content of PLs were in the muscle of BSC. Twenty types of fatty acids were quantified in TL from BSC, and there were higher concentrations of polyunsaturated fatty acids (PUFAs), essential fatty acids (EFAs) and arachidonic acid (AA) in TL from BSC than in muscle from the other two chicken breeds. AA was found to be the dominant PUFA in PLs from all breeds, with the highest PUFA content in PLs from BSC. TL from BSC was found to have anti-fatigue and anti-hypoxic activities, and inhibit isoproterenol-induced oxygen consumption. These results indicate that BSC has superior quality and bioactivity compared with the other two chicken breeds.
