The fatty acid composition was determined on the lipids extracted from chicken muscles (breast, thigh, leaflet muscle in breast, neck), skin, and internal organs (gizzard, heart, spleen, liver). Samples were obtained from "Yamato" and "Broiler" type chickens that were raised in the experiment station. Five of saturated fatty acids (C14:0, C16:0, C18:0, C20:0, C24:0), 5 of monounsaturated fatty acids (C15:1, C16:1, C18:1, C20:1, C24:1) and 5 of poly-unsaturated fatty acids (C18:2, C20:3, C20:4, C22:4, C22:5) were detected by using a gas chromatograph-mass spectrometer. The distribution of 7 kinds of fatty acids (C14:0, C16:0, C16:1, C18:0, C18:1, C18:2, C20:4) which exist more than the other fatty acids were investigated. As the results, the predominant fatty acids of lipids were C18:1, C16:0, C18:0, C18:2, and C20:4 acids. Particularly, C18:1 and C16:0 acids were abundant in breast, thigh, leaflet muscle in breast, neck, skin, and gizzard, on the contrary C20:4 acid was more in heart than in others. The fatty acid composition between "Yamato" and "Broiler" was similar in all positions.
