Resumo: | The objective of this study was to evaluate the effect of three carbohydrate sources (corn, soybean hulls or wheat bran) in the diet on performance, carcass characteristics and meat and the components are not part of the carcass of steers finished on confinement. We used 24 steers, crossbred Charolais x Nellore, with initial age of 22 months of initial body weight 353.2 ± 10.6 kg. The animals were fed a diet with roughage: concentrate 40,2:59,8, and the volume consisting of sorghum silage. The daily intakes of DM and CP were not influenced by sources of carbohydrates. Animals fed soybean hulls had higher intake of NDF and ADF, whereas calves receiving corn consumed higher levels of NFC, and TDN ED. Animals fed corn or soybean hulls had greater weight gain and better feed conversion than steers receiving wheat bran. The slaughter weight was similar between the sources of carbohydrates, averaging 429.81; 433.18 and 430.46 kg for maize, soybean hulls and wheat bran, respectively. The weight cut sidecut was greater for steers fed corn diet compared with soybean hulls or wheat bran. The meat from the diet with soybean hulls had better flavor compared to the wheat bran. The loss of the cooking liquid and cholesterol content were higher in animals treated with maize as compared to those receiving soybean hulls or wheat bran. There was no effect of carbohydrate sources on the weights of vital organs and blood. The absolute and relative weights to the weight of empty body fat of the intestines and rumen were higher in animals fed with corn. The weight of the omasum was greater for the diet with wheat bran, while animals fed soybean hulls had higher absolute weight of kidney fat. |

Foram utilizados 24 novilhos castrados, mestiços Charolês x Nelore, com idade inicial de 22 meses e peso inicial de 353,2±10,6 kg. Os animais foram alimentados com dieta com relação volumoso:concentrado de 40,2:59,8, sendo o volumoso constituído de silagem de sorgo. Os consumos diários de MS e PB não foram influenciados pelas fontes de carboidratos. Animais alimentados com casca de soja apresentaram maiores ingestão de FDN e FDA, enquanto que os novilhos que receberam milho consumiram maiores teores de CNF, NDT e ED. Animais alimentados com milho ou casca de soja apresentaram maior ganho de peso e melhor conversão alimentar em relação aos novilhos que receberam farelo de trigo. O peso de abate foi similar entre as fontes de carboidratos, com médias de 429,81; 433,18 e 430,46 kg, para o milho, casca de soja e farelo de trigo, respectivamente. O peso do corte costilhar foi maior para os novilhos alimentados com milho em comparação a dieta com casca de soja ou farelo de trigo. A carne proveniente da dieta com casca de soja apresentou melhor palatabilidade em relação à do farelo de trigo. As perdas de líquidos à cocção e o conteúdo de colesterol foram maiores na carne dos animais tratados com milho em relação aos que receberam casca de soja ou farelo de trigo. Não houve efeito das fontes de carboidratos sobre os pesos dos órgãos vitais e de sangue. Os pesos absolutos e relativos ao peso de corpo vazio dos intestinos e da gordura ruminal foram maiores nos animais alimentados com milho. O peso de omaso foi maior para a dieta com farelo de trigo, enquanto que os animais alimentados com casca de soja apresentaram maior peso absoluto de gordura renal.Conselho Nacional de Desenvolvimento Científico e Tecnológicoapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em ZootecniaUFSMBRZootecniaCarcaça e carneConfinamentoConsumo de nutrientesCorpo vazioNutrição de ruminantesSubprodutos da agroindústriaAgroindustrial by-productsCarcass and meatConfinementEmpty bodyNutrient intakeRuminant nutritionCNPQ::CIENCIAS AGRARIAS::ZOOTECNIAFontes de carboidratos para terminação de bovinos de corte: desempenho e características da carcaça e da carneSources of carbohydrates for steers finishing: performance and carcass characteristics and meatinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisBrondani, Ivan Luizhttp://lattes.cnpq.br/5813089147720195Alves Filho, Dari Celestinohttp://lattes.cnpq.br/2140386505744337Neiva, José Neuman Mirandahttp://lattes.cnpq.br/9943029201484449Viegas, Juliohttp://lattes.cnpq.br/6750187644177333Peixoto, Luiz Antero de Oliveirahttp://lattes.cnpq.br/8354458929660920http://lattes.cnpq.br/1152835050307149Freitas, Leandro da Silva500400000002400300300300300300300734f41d9-cb39-4ca4-81e7-b1d776cdc0dbf9f719f8-266c-4e58-b53d-1089e333b4ebe5834d46-c91a-4bed-a42a-b8fbc60b47ef9f703545-6b53-4419-9500-786c180696460f2478af-db45-4dc0-9d7d-88088849fd6b47cf5e14-593c-4d2a-8428-f616a7cded1binfo:eu-repo/semantics/openAccessreponame:Repositório Institucional Manancial UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALFREITAS, LEANDRO DA SILVA (2).pdfTese de Doutoradoapplication/pdf1009851http://repositorio.ufsm.br/bitstream/1/4328/1/FREITAS%2c%20LEANDRO%20DA%20SILVA%20%282%29.pdfa72b4d444b99de41fd75d30577635dc2MD51TEXTFREITAS, LEANDRO DA SILVA (2).pdf.txtFREITAS, LEANDRO DA SILVA (2).pdf.txtExtracted texttext/plain274212http://repositorio.ufsm.br/bitstream/1/4328/2/FREITAS%2c%20LEANDRO%20DA%20SILVA%20%282%29.pdf.txt793ea296bd1d797f88d570fb0fbf724fMD52THUMBNAILFREITAS, LEANDRO DA SILVA (2).pdf.jpgFREITAS, LEANDRO DA SILVA (2).pdf.jpgIM Thumbnailimage/jpeg4855http://repositorio.ufsm.br/bitstream/1/4328/3/FREITAS%2c%20LEANDRO%20DA%20SILVA%20%282%29.pdf.jpgb62278a9a2e0afc62f29d2e2034465c3MD531/43282023-05-26 09:32:38.183oai:repositorio.ufsm.br:1/4328Repositório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestouvidoria@ufsm.bropendoar:39132023-05-26T12:32:38Repositório Institucional Manancial UFSM - Universidade Federal de Santa Maria (UFSM)false |
