Resumo: | The objective was to evaluate fatty acids composition of the back fat in loin meat (Longissimus muscle) from Nellore and Canchim young bulls. The animals were finished at feedlot and received sugar cane diets with two concentrate levels (40 and 60% of dry matter). The concentrates were formulated with sunflower grains, corn, soybean meal, dry sugar cane yeast, urea and mineral mixture. The experimental design was a completely randomized design with a 2x2 factorial arrangement (genetic group x concentrate level), and the results were submitted to the variance analysis and means compared by Tukey test at 5% probability, when the interaction was significant. The loin backfat of Nellore bulls had higher concentration of conjugated linoleic acids than Canchim bulls (0.86 and 0.59%, respectively). On the other hand, the loin back fat of Canchim bulls had higher concentrations of estearic (17.07%) and linoleic acids (2.40%) and polyunsaturated fatty acids than Nellore bulls, that showed values of 13.47 and 1.44, respectively. The Nellore and Canchim loin back fat presents significant amounts of beneficial fatty acids to human health. Levels of 40 and 60% of concentrate in the diet did not alter the fatty acids composition of loin backfat. |

Os animais foram terminados em confinamento e alimentados com dietas contendo cana-de-açúcar e duas proporções de concentrado (40 e 60% na matéria seca). Os concentrados foram compostos por grãos de girassol, milho, farelo de soja, levedura seca de cana-de-açúcar, uréia e núcleo mineral. O delineamento experimental foi o inteiramente ao acaso, em esquema fatorial 2x2 (grupo genético x nível de concentrado), sendo os resultados submetidos à análise de variância e as médias comparadas pelo teste de Tukey a 5% de probabilidade, quando a interação foi significativa. A gordura de cobertura dos animais Nelore apresentou maior concentração de ácido linoléico conjugado do que a dos animais Canchim (0,86 e 0,59%, respectivamente). Por outro lado, a gordura de cobertura dos animais Canchim apresentou maior concentração de ácido esteárico (17,07%), linoléico (2,40%) e ácidos graxos polinsaturados do que a dos animais Nelore, que mostraram valores de 13,47 e 1,44%, respectivamente. A gordura de cobertura do contrafilé dos animais Canchim e Nelore apresenta quantidades significativas de ácidos graxos benéficos à saúde humana. Teores de 40 e 60% de concentrado na dieta não alteram a composição em ácidos graxos na gordura de cobertura.UEL2014-02-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa empírica de campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1277910.5433/1679-0359.2014v35n1p467Semina: Ciências Agrárias; Vol. 35 No. 1 (2014); 467-476Semina: Ciências Agrárias; v. 35 n. 1 (2014); 467-4761679-03591676-546Xreponame:Semina.
