| Total lipid (TL), phospholipids (PLs) and fatty acids composition were determined in the muscles of black bone silky fowl (BSF) and other two common chicken breeds which were bred in the same feeding conditions. Among all the chicken groups investigated, the lowest content of total lipid (5.41%) and the highest content of phospholipids (0.55%) were found in BSF. 20 fatty acids in total lipid of BSF were quantified by GC-MS, and it was characterized with higher polyunsaturated fatty acids (PUFAs, 26.64%), essential fatty acids (EFAs, 20.17%) and arachidonic acid (AA, 3.21%) than that of other breeds. AA was found to be the dominant PUFA in phospholipids form all breeds, especially in phospholipids of BSF with the highest content up to 21.39%. During the testing of anti-fatigue and antihypoxic activities it was found that the total lipid of BSF had significant anti-fatigue, antihypoxic activities and capacity to depress the isoproterenol-induced oxygen consumption increase. These results indicate that BSF has better quality and functions in comparison with common chickens, and they could be used as a factor to verify the therapeutical efficacy of BSF which has long been used in traditional Chinese medicine.
