Abstract The purpose of this paper was to study the difference in fatty acid contents in muscles of Qinghua, Chahua 2 and white feathered broilers. Intramuscular fat was extracted by the chloroform-methanol method, methylated and detected by high performance gas chromatography for the contents of 18 fatty acids. The results showed that palmitic acid (C16:0), stearic acid (C18:0), oleic acid (C18:1 n-9c) and linoleic acid (C18:2 n-6c) were the most dominant fatty acids in chicken muscles for the three breeds. The content of saturated fatty acids (SFA) in the breast muscle of male Qinghua broilers was significantly higher than in the breast muscle of male white feathered broilers (P < 0.05), and the content of essential fatty acids (EFA) in the breast muscle of male Chahua 2 broilers was significantly higher than in the breast muscle of male Qinghua broilers and male white feathered broilers (P < 0.05). The contents of SFA and unsaturated fatty acids (UFA) in the breast muscle of female Qinghua broilers and female Chahua 2 broilers were significantly higher than in the breast muscle of female white feathered broilers (P < 0.05), and the content of EFA in the breast muscle of female Chahua 2 broilers was significantly higher than in the breast muscle of female white feathered broilers and female Qinghua broilers (P < 0.05). SFA content in the thigh muscle of male Chahua 2 broilers was significantly higher than in the thigh muscle of male broilers from the other breeds (P < 0.05), and the contents of EFA and UFA in the thigh muscle of male Chahua 2 broilers and male white feathered broilers were significantly higher than in the thigh muscle of male Qinghua broilers (P < 0.05). SFA content in the thigh muscle of female Qinghua broilers was significantly higher than in the thigh muscle of female white feathered broilers (P < 0.05), but not significantly different from Chahua 2 broilers. The contents of monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA) in breast and thigh muscles were different among broiler breeds. To sum up, although different from one another, the fatty acid composition of muscles from the three broiler breeds could meet the requirements for human health.
