The aim of this study was to analyze the chemical composition and the fatty acids (FA) profile of broiler chicken (breast and thigh/on-thigh) fed diets containing 10 and 20% of barley and a control diet. The FAs were evaluated by gas chromatography. There was not a significant difference (p > 0.05) in the breast chemical composition. In the thigh/on-thigh cut, the ration containing 20% of barley reduced the ashes (p < 0.05). Regarding the saturated FA composition, only the breast myristic acid treated with 10% of barley was reduced (p < 0.05). None of the diets influenced the polyunsaturated (PUFA) and monounsaturated (MUFA) FA's content (p > 0.05). As for the ω6/ω3 ratio, the highest one was observed in the 20% barley fed animals, in both cuts, being considered the worst quality. It can be concluded that the 20% barley ration was worse than the others and the 10% barley ration was better than the control ration, especially when considering the saturated FA quantity that was reduced.293495503(2007) História da Agrária, , http://www.agraria.com.br/brasil/pagina.php?menu=comunicacao_noticia &banner=comunicacao&comunicacao_noticia=mostra_noticia&idnoticia =386, AGRARIA - Cooperativa Agrária Mista Entre Rios, Disponível em, Acesso em: DezembroAnderson, J.W., Hanna, T.J., Impact of nondigestible carbohydrates on serum lipoproteins and risk for cardiovascular disease (1999) The Journal of Nutrition, 129 (7), pp. 1475S-1466sFat (Crude) or Ether Extract in Animal Feed (1995) Official methods of analysis of AOAC international, (1), p. 17. , Association of Official Analytical Chemistry - AOAC., In, 16 ed.
