Longissimus dorsi fatty acids composition of Bos indicus and Bos indicus x Bos taurus crossbred steers finished in pasture
Studies were carried out to evaluate the fatty acids composition of Longissimus dorsi muscle, with or without fat thickness, of Bos indicus and Bos indicus x Bos taurus crossbred steers finished in millet (Pennisetum americanum L.) or star grass (Cynodon plectostachyus Pilger) pasture systems with m...

| description | Studies were carried out to evaluate the fatty acids composition of Longissimus dorsi muscle, with or without fat thickness, of Bos indicus and Bos indicus x Bos taurus crossbred steers finished in millet (Pennisetum americanum L.) or star grass (Cynodon plectostachyus Pilger) pasture systems with mineral or mineral protein supplementation. Neither the treatment nor the genetic group had effect on meat fatty acids composition. The cut had effect on meat fatty acid composition. The meat without fat thickness had 11% of PUFA, 43% of MUFA and 45% of SFA. The meat with fat thickness had 5% of PUFA, 44% of MUFA and 50% of SFA. PUFA/SFA ratio was 0.10 and 0.25 and n-6/n-3 ratio was 0.80 and 1.27 for cuts with and without fat thickness.<br>O objetivo deste trabalho foi avaliar a composição em ácidos graxos do músculo Longissimus dorsi, com ou sem gordura de cobertura, de novilhos Bos indicus e mestiços Bos indicus x Bos taurus, terminados em pastagem de milheto (Pennisetum americanum L.) ou grama estrela (Cynodon plectostachyus Pilger), com suplementação mineral ou protéica e mineral. A composição em ácidos graxos da gordura intramuscular e da gordura de cobertura do músculo Longissimus dorsi foram analisadas por cromatografia gasosa. Não houve efeito do tratamento e do grupo genético sobre a composição em ácidos graxos da carne. Houve efeito de corte na composição em ácidos graxos da carne. A carne sem gordura de cobertura apresentou 11% de AGPI, 43% de AGMI e 45% de AGS. A carne com gordura de cobertura apresentou 5% de AGPI, 44% de AGMI e 50% de AGS. A relação AGPI/AGS foi de 0,10 e 0,25 e a relação n-6/n-3 foi de 0,80 e 1,27 para os cortes com e sem gordura de cobertura. |
