Abstract: The objective of this study was to analyze the fatty acid content of ovine meat to two different breeds, Morada Nova and UB (Undefined Breed) from Northeastern Brazil. Ovine lipid used from animals raised on a farm at Quixadá-Ceará, ribs, loin, shoulder and leg. The lipid extraction was performed by the Folch method. The fatty acid analysis was conducted by Gas Chromatography coupled with Mass Spectrometry (GC/MS). The result of the variance analysis demonstrated that these was no correlation between genetic type and cut. Analyzing the fatty acid content of each cut, these were significant changes for C 14:0; C16:1; C18:0 and C18:2 fatty acids. In the Morada Nova breed, unsaturated fatty acid content was higher than of UB animals. The data obtained were compared with those published in other counties, verifying that ovine from cold climate regions present higher unsaturated fatty acid levels in the intramuscular lipid than those found in the present study with animals from northeastern Brazil.

Resumo: O objetivo deste trabalho é analisar o tipo de ácidos graxos da carne ovina consumida no Nordeste do Brasil de duas raças diferentes, Morada Nova e animais sem raça definida (SRD). Utilizou-se a gordura intramuscular de ovinos criados numa fazenda em Quixadá-Ceará, separando-se os cortes: costilhar, lombo, paleta e perna. A extração lipídica deu-se pelo método de Folch. Os ácidos graxos foram analisados por Cromatografia de Gás combinada à Espectrometria de Massa (CG/EM). O resultado da análise de variância demonstrou que não ocorreu uma correlação entre tipo genético e corte. No estudo isolado dos cortes foram verificadas alterações significativas para os ácidos graxos C 14:0; C16:1; C18:0 e C18:2. Na raça Morada Nova, o conteúdo de ácidos graxos insaturados foi mais elevado que dos animais SRD. Os dados obtidos foram comparados com os publicados em outros países, verificando-se que os ovinos de regiões de clima frio apresentam uma quantidade de ácidos graxos insaturados na gordura intramuscular maior que o encontrado no presente estudo com animais do Nordeste brasileiro MenosAbstract: The objective of this study was to analyze the fatty acid content of ovine meat to two different breeds, Morada Nova and UB (Undefined Breed) from Northeastern Brazil.

Napier grass (Pennisetum purpureum Schum.) is an important forage crop in tropical areas although little is known about its genome information, and few molecular markers have been developed for this species. This work aimed to check the viability of cross-species amplifi cation of microsatellite markers between pearl millet (Pennisetum glaucum) and Napier grass and to evaluate the genetic diversity among Napier grass germplasm accessions. Fifty-four microsatellite markers previously described in pearl millet were tested against Napier grass, and 30 markers (55.5%) showed successful cross-amplifi cation. From them, 18 microsatellite markers were selected to study the genetic diversity in the Embrapa Active Germplasm Bank of Napier Grass (Embrapa-BAGCE). A total of 180 alleles were identifi ed by these selected microsatellite markers in 107 Napier grass accessions and four pearl millet samples. The average similarity coeffi cient (Dice) calculated among the Embrapa-BAGCE accessions was 0.651, ranging from 0.254 to 1.0. Some accessions showed similarity coeffi cients equal to one, indicating that they have common progenitors or that they might be the same accessions with different denomination. To our knowledge, this work is the fi rst to describe microsatellite markers in Napier grass and represents a signifi cant advance regarding the use of molecular markers in this specieS |
