Summary: The aim of this study was to evaluate the fatty acid profile of the meat of buffalo finished in creating Traditional Systems (ST) and Silvopastoral (SSP) with supplemental feeding. The experiments were performed in the Research Units Animal "Senator Álvaro Adolpho", silvopastoral system and "Dr. Philibert Camargo, "traditional system of creation, belonging to Embrapa Amazônia Oriental, Belém-Pará, Brazil. After the fattening period, eight months, the animals were slaughtered at a commercial abattoir and their carcasses identified, refrigerated for 24 hours. The Longissimus dorsi (kebabs) retained the right half carcass between the 12th and 10th ribs, was ground and stored for determination of acids in lipids extracted from samples and cold reading esters performed by gas chromatography. The experimental design was completely randomized, the data were evaluated by ANOVA and means were compared by 't' test at 5% significance level. The analysis of fatty acid profile reveals a statistical difference (P <0.05), only the percentage of myristic acid (C14: 0) and polyunsaturated fatty acids. In conclusion, therefore, that breeding systems and supplementation are not sufficient to indicate the use of either system, since it must be taken into account also the environmental, social and economic.
