Resumo: The objective of this study was to estimate the (co) variances and genetic associations between the visual scores of conformation and precocity at weaning and at yearling, respectively WC, WP and YC, YP with the characteristics of average daily gain (BWG: from birth to weaning and WYG: from weaning to yearling) and rate of weight gain (BWR: from birth to weaning and BYR: from weaning to yearling) for Angus cattle. The (co)variances components were estimated by multi-traits analysis using an animal model by Bayesian Inference Method, assuming a linear model for average daily gain and for rate of weight gain and a non-linear (threshold) for WC, WP, YC and YP. The a posteriori means for direct heritability were 0.12 (WC), 0.17 (WP), 0.15 (BWG and BWR), 0.17 (YC), 0.19 (YP) and 0.16 (WYG and BYR). The genetic correlation between the weaning and yearling scores with the direct effect for the average daily gain and rate of weight gain traits ranged from -0.05 to 0.60 for conformation and -0.15 to 0.60 for precocity; the genetic correlation of the scores with average daily gain and rate of weight gain presented similar behavior. Therefore, correlated response of equal magnitude is expected for scores, if the selection was directed to average daily gain or rate of weight gain.

Os componentes de (co)variâncias foram estimados por um modelo animal tetra-característica usando o Método de Inferência Bayesiana, assumindo um modelo linear para o ganho médio diário e velocidade de ganho de peso e um modelo não-linear (de limiar) para CD, CS, PrD e PrS. As médias a posteriori para a herdabilidade direta foram: 0,12 (CD); 0,17 (PrD); 0,15 (GMD e VD); 0,17 (CS); 0,19 (PrS) e 0,16 (GMS e VS). As correlações genéticas estimadas entre os escores à desmana e ao sobreano com o efeito direto para as caracteristicas de crescimento variaram de -0,05 a 0,60 para conformação e de -0,15 a 0,60 para precocidade; a correlação genética dos escores com ganho médio diário ou com velocidade de ganho de peso apresentou comportamento semelhante. Portanto, resposta correlacionada de igual magnitude é esperada para os escores, se a selação for direcionada para ganho médio diario de peso ou velocidade de ganho de peso.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em ZootecniaUFSMBRZootecniaAmostragem de gibbsCaracterísticas produtivasGado de corteMétodo de Monte CarloBeef cattleGibbs samplingMonte Carlo methodProduction traitsCNPQ::CIENCIAS AGRARIAS::ZOOTECNIAEscores visuais e associação com características de crescimento em bovinos da raça AngusVisual scores and association with characteristics of growth in cattle Angusinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisRorato, Paulo Roberto Nogarahttp://lattes.cnpq.br/6804416984369871Mello, Fernanda Cristina Bredahttp://lattes.cnpq.br/9702654931601290Boligon, Arione Augustihttp://lattes.cnpq.br/5203662694720338Cobuci, Jaime Araujohttp://lattes.cnpq.br/2682793411821068Pacheco, Paulo Santanahttp://lattes.cnpq.br/9700645244479913http://lattes.cnpq.br/7623648172038212Everling, Dionéia Magda500400000002400300300300300300300bb5914a5-24ef-4ddb-98d2-5e4c9314762beaccc870-be93-4e18-b612-5fec960ecf91e0b01437-76ad-4579-83d4-6cd084a3c44a49f50262-90ea-4b10-a5df-03d2eb09d9f5587e1bfb-0dce-483c-839a-e083e02dee461fcee2f4-a2da-4564-a5e6-62e4272487f4info:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALEVERLING, DIONEIA MAGDA.pdfTese de Doutoradoapplication/pdf4399846http://repositorio.ufsm.br/bitstream/1/4333/1/EVERLING%2c%20DIONEIA%20MAGDA.pdf93f8bbc6b5368ecf6ca5c708705ec10bMD51TEXTEVERLING, DIONEIA MAGDA.pdf.txtEVERLING, DIONEIA MAGDA.pdf.txtExtracted texttext/plain150520http://repositorio.ufsm.br/bitstream/1/4333/2/EVERLING%2c%20DIONEIA%20MAGDA.pdf.txta9c3c10d1e5d54ad1c082826de24971dMD52THUMBNAILEVERLING, DIONEIA MAGDA.pdf.jpgEVERLING, DIONEIA MAGDA.pdf.jpgIM Thumbnailimage/jpeg4843http://repositorio.ufsm.br/bitstream/1/4333/3/EVERLING%2c%20DIONEIA%20MAGDA.pdf.jpg8672bed8abd05fb878be675e9787f0e9MD531/43332022-08-11 12:47:05.396oai:repositorio.ufsm.br:1/4333Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2022-08-11T15:47:05Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false
