Resumo: The objective of this study was to evaluate the meat and carcass characteristics of feedlot steers finished in different individual spaces. We used 48 steers, with average initial age and weight of 20 months and 243.4 kg, respectively. The animals were placed in collective stalls and distributed into treatments according to the available individual space, 2.5; 5.0 and 10 m2. The diet contained roughage:concentrate relation of 39:61 (dry matter basis). Individual spaces did not influence hot and cold carcass weight, means of 226.0 and 222.1 kg, respectively, as well their respective carcass dressing, 58.5 and 57.0 kg/ 100 kg live weight. For all treatments, the carcasses showed the minimum fat thickness required, 3 mm, being similar among the different individual spaces evaluated. The weight and percentage of commercial cuts, the absolute weight and the tissue participation in the carcass were similar among the individual spaces. The pH and temperature in Longissimus dorsi and Recto femoralis muscles were not altered by individual spaces. Color, texture, marbling, and the meat sensorial characteristics (tenderness, juiciness and palatability) were not influenced by different individual spaces. The shear force showed mean of 5.06 kgF/cm3. The number of lesions, location and time of occurrence was not influenced by different individual space. The individual space for feedlot steers during finishing did not influence carcass and meat characteristics, when slaughtered at 24 months of age.KEYWORDS: animal welfare; carcass dressing; carcass lesions; restrict space; tenderness.

Foram utilizados 48 novilhos, com idade e pesos médios iniciais de 20 meses e 243,4 kg, respectivamente, confinados em baias coletivas, distribuídos nos tratamentos conforme o espaço individual disponível, 2,5; 5,0 ou 10 m2. A dieta continha relação volumoso:concentrado de 39:61 (base na matéria seca). Os pesos de carcaça quente e fria, médias de 226,0 e 220,1 kg, respectivamente, e seus rendimentos, 58,5 e 57,0 kg/ por 100 kg de peso vivo, citados na mesma ordem, não foram influenciados pelo espaço individual disponível. Para todos os espaçamentos avaliados, as carcaças apresentaram espessura de gordura mínima exigida, 3 mm, sendo similar entre os diferentes espaçamentos avaliados. O peso dos cortes comerciais da carcaça e seus rendimentos, como também o peso absoluto e a participação dos tecidos que compõem a carcaça foram similares entre os diferentes espaços individuais. Os valores de pH e temperatura nos músculos Longissimus dorsi e Recto femoralis não foram afetados pelos espaçamentos individuais. Cor, textura, marmoreio e as características organolépticas da carne não foram influenciadas pelos espaçamentos utilizados. A força de cisalhamento apresentou valor médio de 5,06 kgF/cm3. O número de lesões, local e tempo de ocorrência das mesmas não foi influenciado pelos diferentes espaços individuais. O espaço individual na terminação de novilhos em confinamento não influenciou as características da carcaça e da carne, quando abatidos aos 24 meses de idade.PALAVRAS-CHAVE: bem-estar animal; espaço restrito, lesões na carcaça, maciez, rendimento de carcaça.Universidade Federal de Goiás2013-06-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionresearchAvaliado por paresPesquisa científicaapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/2270310.5216/cab.v14i2.22703Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 14 No. 2 (2013); 185-198Ciência Animal Brasileira / Brazilian Animal Science; v. 14 n. 2 (2013); 185-1981809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/22703/14519https://revistas.ufg.br/vet/article/view/22703/14520Cattelam, JonatasBrondani, Ivan LuizAlves Filho, Dari CelestinoSegabinazzi, Luciane RumpelCallegaro, Alisson MarianMichelon, Jozianeinfo:eu-repo/semantics/openAccess2013-06-28T13:39:56Zoai:ojs.revistas.ufg.br:article/22703Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:57.695327Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true
