Analysis on Fatty Acid Components in Muscle Tissues of the Hongshan Chicken

The muscle fatty acid content of the Hongshan chicken was determined. The results showed that oleic acid,linoleic acid,palmitic acid and stearic acid were the most of the muscle fatty acid composition and the unsaturated fatty acids(USFA) was the main part. Under the stocking model,between the male and the female of the Hongshan chicken,the fatty acid content of all kinds except monounsaturated fatty acids(MUFA) had no significant difference. In the Hongshan hen,the content of Polyunsaturated fatty acids(PUFA) and essential fatty acids(EFA) in stocking model was signigicantly higher than that in captivity conditions(P0.05) ,other fatty acids content had not significant difference(P0.05) . In capitivity conditions,EFA content of leg muscle and chest muscle of the Hongshan hen was significantly higher than that of lingnan yellow hen(P0.05) . Four types of samples,the content of PUFA and EFA in the leg muscle of the cage Hongshan hen or the Hongshan stocking hen were significantly higher than that in the chest muscle(P0.05) .
