Resumo: | Thirty eight (38) castrated male goats were used to evaluate carcass tissue and regional composition. Animals were raised under extensive range conditions, in two family units, in the 2nd sub-district of Palmas, Bagé, State of RS, Brazil, localized within the area known as Alto Camaquã Territory. Twenty (23) animals born during June/July 2008, and were slaughtered in June 2009, with approximately 11-12 months of age. Fifteen (15) animals born in March/April 2009 were slaughtered in December 2009, with approximately 8-9 months of age. Carcasses were separated longitudinally in two halves. Afterwards six cuts were obtained: foreleg, hind-leg fluctuating ribs, fixed ribs, neck and breast, each one being weighed, to calculate the proportion in relation to the corrected cold carcass weight. Different cuts obtained were frozen for later tissue evaluation. Foreleg and hind-leg were defrosted and dissect to determine muscle tissue composition, bone, subcutaneous fat, inter-muscular fat and other tissues. Each resulting tissue was weighed and its proportion calculated in relation to the corrected weight. Data were submitted to variance analysis (proc. GLM). Results demonstrated significant differences (P<0.05) between the age of slaughter in carcass regional components, whereas foreleg and hind-leg tissue composition did not differ significantly for the majority of the variables analyzed. However, 8-9 months goats showed greater relation for muscle:fat in foreleg compared to 11-12 months animals. Thus, naturalized goats of the Alto Camaquã Territory, grown extensively and slaughtered in December, or slaughtered in June with 11-12 months age, presented different tissue and regional composition in carcasses. Therefore, it is not recommended to include these two group types in a same meat brand (indication of quality) classification. |

Parte destes animais (23) nasceu entre os meses de junho e julho de 2008 e foi abatido em junho de 2009, com aproximadamente 11-12 meses de idade. O restante dos animais (15) nasceu entre os meses de março e abril de 2009 e foi abatido em dezembro do mesmo ano com, aproximadamente, 8-9 meses de idade. Após o abate as carcaças foram divididas longitudinalmente em duas metades. Posteriormente, foram obtidos seis cortes: paleta, perna, costelas flutuantes, costelas fixas, pescoço e peito, sendo cada um deles pesado e calculada sua proporção em relação ao peso da meia carcaça fria corrigido. Os diferentes cortes obtidos foram congelados para posterior avaliação tecidual. Os cortes de paleta e perna foram submetidos a descongelamento e dissecados, para determinação da composição tecidual em músculo, osso, gordura subcutânea, gordura intermuscular e outros tecidos. Cada tecido que compunha os cortes foi pesado e sua proporção calculada em relação ao peso do corte corrigido. Os dados foram submetidos à análise de variância (procedimento GLM). Os resultados demonstraram que foram encontradas diferenças significativas (P<0,05) entre idade de abate nos componentes regionais da carcaça, enquanto que, no que se refere à composição tecidual da paleta e da perna não foram encontradas diferenças significativas na maior parte das variáveis analisadas. Porém, cabritos aos 8-9 meses tiveram maior relação músculo:gordura na paleta que os cabritos aos 11-12 meses. Deste modo, cabritos naturalizados do Território Alto Camaquã , criados em sistema extensivo, abatidos em dezembro com 8-9 meses e abatidos em junho com 11-12 meses de idade apresentam carcaças com composição regional e tecidual distintas, não sendo recomendado estarem em uma mesma marca de carne.application/pdfporUniversidade Federal de PelotasPrograma de Pós-Graduação em ZootecniaUFPelBRFaculdade de Agronomia Eliseu MacielCarneGorduraMúsculoRendimento em cortesSistema extensivoMeatFatMuscleCuts yieldingExtensive systemCNPQ::CIENCIAS AGRARIAS::ZOOTECNIAComposição regional e tecidual da carcaça de cabritos naturalizados do Alto Camaquã de diferentes idades.Carcass tissue and regional composition of naturalized goats from the Alto Camaquã region at different ages.info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFPel - Guaiacainstname:Universidade Federal de Pelotas (UFPEL)instacron:UFPELORIGINALDissertacao_Luciane_Silva_Martins.pdfapplication/pdf555347http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2586/1/Dissertacao_Luciane_Silva_Martins.pdf0b7fbb035e111d7955facc7abe839ff2MD51open accessTEXTDissertacao_Luciane_Silva_Martins.pdf.txtDissertacao_Luciane_Silva_Martins.pdf.txtExtracted Texttext/plain75264http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2586/2/Dissertacao_Luciane_Silva_Martins.pdf.txtf71a190ffa1361cdcc9bd5016cfa6cceMD52open accessTHUMBNAILDissertacao_Luciane_Silva_Martins.pdf.jpgDissertacao_Luciane_Silva_Martins.pdf.jpgGenerated Thumbnailimage/jpeg1356http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2586/3/Dissertacao_Luciane_Silva_Martins.pdf.jpg6d5a2fe3b460a1e998fe0d559ed339d5MD53open access123456789/25862022-11-29 10:31:57.473open accessoai:guaiaca.ufpel.edu.br:123456789/2586Repositório InstitucionalPUBhttp://repositorio.ufpel.edu.br/oai/requestrippel@ufpel.edu.br || repositorio@ufpel.edu.br || aline.batista@ufpel.edu.bropendoar:2022-11-29T13:31:57Repositório Institucional da UFPel - Guaiaca - Universidade Federal de Pelotas (UFPEL)false |
