Resumo: | This work was conducted in order to study the chemical composition, fatty acid profile, as well as the levels of n-3 and n-6 fatty acids and conjugated linoleic acid (CLA) present in the Longissimus muscle of Caracu and Caracu vs. Charolais genetic groups of cattle. This study was carried out at the Experimental Farm of the Agronomic Institute of Paraná, in southern Brazil. Twenty animals (10 Caracu – CAR and 10 Caracu vs. Charolais – CAC) were used, with an initial average age between 8 and 10 months. The young bulls were slaughtered at 450 kg and 18 months of age. The moisture and crude protein percentages were similar between the two genetic groups. However, the percentage of ash was higher in the CAC group. Conversely, total lipid levels was lower in the CAC group. The fatty acid profiles were similar for CAR and CAC bulls. Percentages of polyunsaturated fatty acids (PUFA) and n-6 were higher in the CAC group. The monounsaturated fatty acid (MUFA), saturated fatty acid, and n-3 percentages, as well n-6/n-3 and PUFA/MUFA ratios, were similar between CAR and CAC bulls. The 18:2 n-6, 18:2 c – 9 t – 11 and 20:3 n-6 contents (mg/g of total lipids) were higher in the CAR group. |

Este trabalho foi realizado para estudar a composição química, perfil de ácidos graxos e a quantificação dos ácidos graxos n-3, n-6 e ácido linoléico conjugado (CLA) no músculo Longissimus de bovinos inteiros dos grupos genéticos Caracu e Caracu vs. Charolês. Este estudo foi realizado na Fazenda Experimental do Instituto Agronômico do Paraná. Foram utilizados vinte animais (10 – Caracu – CAR e 10 Caracu vs. Charolês – CAC) com idade inicial de 8-10 meses. Os animais foram abatidos com peso médio de 450 kg e 18 meses. A percentagem de umidade e proteína total foram similar entre os dois grupos genéticos. Entretanto, a percentagem de cinzas foi maior no grupo CAC. Ao contrário, a percentagem de lipídeos totais foi menor no grupo CAC. O perfil de ácidos graxos foi similar entre os animais CAR e CAC. A percentagem de ácidos graxos poliinsaturados (AGPI) e n-6 foi maior para animais do grupo CAC. As percentagens de ácidos graxos monoinsaturados (AGMI), ácidos graxos saturados (AGS), n-3 e as razões de n-6/n-3 e AGPI/AGS foram similar entre os animais CAR e CAC. A quantificação dos ácidos graxos 18:2 n-6, 18:2 cis 9 trans 11 and 20:3 n-6 (mg/g of total lipids) foi maior em animais do grupo CAR.
