Resumo: | This study aimed to evaluate the carcass quantitative characteristics, tissue composition of carcass cuts and meat quality of lambs receiving sunflower seeds in the diet. Twenty-one lambs 7/8 Ile de France 1/8 Ideal, not castrated, with initial body weight of 17 kg were housed in individual pens and distributed in three diets (0,7.5 and 15% of sunflower seeds inclusion) in a completely randomized design in 3 x 2 factorial arrangement (three diets and two carcass cuts). At the end of the experimental period, the animals were slaughtered; weights and hot and cold carcass yields and commercial and biological carcass dressing were collected. The carcasses were split lengthways and left half carcass divided into six anatomical parts. The leg and loin were removed for evaluation of tissue composition, meat color, water holding capacity, cooking losses and shearing force. Difference was detected in the commercial carcass yield; with higher value (46.82% of total weight) for carcasses of lambs fed without sunflower seeds when compared with carcass yield (44.11%) of lambs fed with 15% of sunflower seed inclusion. The proportion of muscle and total fat, as muscle:fat ratio were affected (P<0.05) by feeding, with higher quantity of muscle (63.15%) and less fat (16.63%) in the leg and loin cuts of lambs fed without sunflower seeds. In the leg was observed higher proportions of muscle (67.27%), muscle:bone ratio (4.08) and muscle:fat ratio (4.92) when compared with the loin cut. The water retention capacity and shearing force of Longissimus lumborum muscle showed better results when compared with Semimembranosus muscle. The inclusion of sunflower seeds in the diet of feedlot lambs increased the fat deposition in carcass cuts, however did not affect the other parameters of meat quality. |

Foram utilizados 21 cordeiros 7/8 Ile de France 1/8 Ideal, não castrados, com peso corporal médio inicial de 17 kg, alojados individualmente e distribuídos em três dietas (0, 7,5 e 15% de grãos de girassol na ração) em delineamento experimental inteiramente casualizado decomposto em modelo fatorial 3x2 (três rações e dois cortes de carcaça). Ao final do período experimental, os animais foram abatidos, obtendo-se os pesos e rendimentos de carcaça quente e fria, além dos rendimentos comercial e biológico da carcaça. As carcaças foram seccionadas longitudinalmente e a meia-carcaça esquerda dividida em seis partes anatômicas, sendo retirado o lombo e a perna para avaliação dos componentes teciduais e características de cor, capacidade de retenção de água, perdas por cocção e força de cisalhamento. Houve diferença para rendimento comercial, com maior valor (46,82%) para carcaças de cordeiros recebendo ração sem inclusão de grãos de girassol em relação ao rendimento de carcaça (44,11%) de cordeiros alimentados com 15% de grãos de girassol. As proporções de músculo e gordura total, assim como a relação músculo:gordura foram influenciadas (P<0,05) pela ração, com maior quantidade de músculo (63,15%) e menor de gordura (16,63%) nos cortes perna e lombo de cordeiros que não receberam grãos de girassol. No corte perna foi observado maiores proporções de músculo (67,27%), relação músculo:osso (4,08) e músculo:gordura (4,92) quando comparado ao lombo. O músculo Longissimus lumborum apresentou maior capacidade de retenção de água e menor força de cisalhamento em relação ao músculo Semimembranosus. A inclusão de grãos de girassol na ração de cordeiros em confinamento aumentou a deposição de gordura nos cortes da carcaça, porém não afetou os demais parâmetros qualitativos da carne.UEL2013-08-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1178610.5433/1679-0359.2013v34n4p1925Semina: Ciências Agrárias; Vol. 34 No. 4 (2013); 1925-1934Semina: Ciências Agrárias; v. 34 n. 4 (2013); 1925-19341679-03591676-546Xreponame:Semina.
