Shrnutí: | The performance, carcass and meat characteristics and economic viability of Nellore cows and heifers feedlot finished during 40 or 60 days were evaluated. The experimental design used was completely randomized with treatments in a 2 x 2 factorial arrangement, with two female categories and two confinement periods. Twenty-two cows with 74.3 months and 22 heifers with 20.4 months were used. The experimental diet included corn silage and concentrate containing 18% CP and 74% NDT. In the 21-days adaptation period, cows showed much lower performance. The food consumption expressed as a percentage of body weight was higher in heifers, with average daily weight gain of 821 and 938 g, while cows practically maintained their weight with average daily weight gain of 62 and -291 g. Heifers were more efficient in feed conversion during adaptation. After the adaptation period, cows showed greater average daily weight gain, with similar feed conversion to heifers. The cold carcass yield was higher (p<0.04) in heifers, which also showed greater subcutaneous fat thickness (P<0.01) with the 40-day finishing, but with no difference to the 60-day finishing. The increase in the feedlot period provided a higher marbling content (P<0.01) in the Longissimus lumborum muscle in both categories, the increase being more evident in cows. The net profit from finishing the heifers was 47.2% higher (P<0.5) in relation to the profit obtained with the cows. |

Foram usadas 22 vacas com 74,3 meses e 22 novilhas com 20,4 meses. A dieta experimental foi formada de silagem de milho e concentrado contendo 18% de PB e 74% de NDT. No período de 21 dias de adaptação vacas apresentaram desempenho bem inferior. O consumo alimentar expresso em percentagem do peso corporal foi maior nas novilhas, com ganho de peso médio diário bem superior, 821 e 938 g, enquanto as vacas praticamente mantiveram o peso com ganho de peso médio diário de 62 e -291g. Novilhas foram mais eficientes na conversão alimentar durante a adaptação. Após o período de adaptação, as vacas apresentaram maior ganho de peso médio diário, com conversão alimentar similar às novilhas. O rendimento de carcaça fria foi maior (P<0,04) nas novilhas, que também apresentaram maior espessura de gordura subcutânea (P<0,01) na terminação de 40 dias, mas sem diferença na terminação de 60 dias. O aumento no período de confinamento propiciou maior teor de marmoreio (P<0,01) no músculo Longissimus lumborum em ambas categorias, sendo o aumento mais evidente nas vacas. O lucro líquido da terminação das novilhas foi 47,2% superior (p<0,5) em relação ao lucro obtido com as vacas.OutroporUniversidade Federal de GoiásPrograma de Pós-graduação em Zootecnia (EVZ)UFGBrasilEscola de Veterinária e Zootecnia - EVZ (RG)Attribution-NonCommercial-NoDerivatives 4.0 Internationalinfo:eu-repo/semantics/openAccessConfinamentoAdaptaçãoTerminaçãoVacasNovilhasFeedlotAdaptationFinishingHeifesCowsCIENCIAS AGRARIAS::ZOOTECNIA::PRODUCAO ANIMALTerminação de vacas e novilhas com diferentes períodos de confinamentoCows and heifers finished in the feedlot during different periodsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesis84500500500500613165reponame:Repositório Institucional da UFGinstname:Universidade Federal de Goiás (UFG)instacron:UFGLICENSElicense.txtlicense.txttext/plain; charset=utf-81748http://repositorio.bc.ufg.br/tede/bitstreams/6a386c15-f586-4f74-b100-008e6a3b8669/download8a4605be74aa9ea9d79846c1fba20a33MD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml; charset=utf-8805http://repositorio.bc.ufg.br/tede/bitstreams/84ec2ebc-5b7a-419f-9fa2-baba22ff1b44/download4460e5956bc1d1639be9ae6146a50347MD52ORIGINALDissertação - Bruno Monteiro Brandão - 2020.pdfDissertação - Bruno Monteiro Brandão - 2020.pdfapplication/pdf578273http://repositorio.bc.ufg.br/tede/bitstreams/31672528-508b-4f9c-9990-b1ef55d9abf4/download1a86eb0e8ced01da1a55635eeebd3f7bMD53tede/111562021-03-17 08:48:00.516http://creativecommons.org/licenses/by-nc-nd/4.0/Attribution-NonCommercial-NoDerivatives 4.0 Internationalopen.accessoai:repositorio.bc.ufg.br:tede/11156http://repositorio.bc.ufg.br/tedeRepositório InstitucionalPUBhttps://repositorio.bc.ufg.br/tedeserver/oai/requestgrt.bc@ufg.bropendoar:oai:repositorio.bc.ufg.br:tede/12342021-03-17T11:48Repositório Institucional da UFG - Universidade Federal de Goiás (UFG)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 |
