Resumo: The aim of this study was to estimate (co)variance components and genetic parameters from birth to yearling weight (550 days of age) in Guzerá cattle, using random regression models. Data set from animals (male and female) born between 1993 and 2011 belonging to ten farms in seven Brazilian States were used. The best-fit model considering direct and maternal genetic effect and permanent environmental animal effect were adjusted by fourth, third, and second order, respectively, using orthogonal polynomials of Legendre. The higher estimated values of direct heritability were observed in birth (0.88) and yearling weight (0.70). The genetic correlations were moderate to high magnitude, remaining up even with the increase in the ages gap. Key words: beef cattle; genetic correlations; heritability; orthogonal polynomials of Legendre.

Os dados utilizados são de animais (machos e fêmeas) nascidos entre 1993 e 2011 e pertencentes a dez fazendas de sete estados brasileiros. O modelo de melhor ajuste considerou os efeitos genéticos aditivos diretos e maternos e os de ambiente permanente do animal ajustado usando polinômios ortogonais de Legendre de quarta, terceira e segunda ordem, respectivamente. As maiores estimativas de herdabilidade diretas foram observadas para os pesos ao nascimento (0,88) e ao sobreano (0,70). As correlações genéticas foram de moderada a alta magnitude, mantendo-se elevada mesmo com o aumento da distância entre as idades. Palavras-chave: bovinos de corte; correlações genéticas; herdabilidade; polinômios ortogonais de Legendre. Universidade Federal de Goiás2017-03-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa CientíficaResearchapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/e-3956610.1590/cab18039566Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 18 (2017): Continuous publicationCiência Animal Brasileira / Brazilian Animal Science; v. 18 (2017): Publicação contínua1809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/e-39566/22681https://revistas.ufg.br/vet/article/view/e-39566/22682Copyright (c) 2017 Ciência Animal Brasileirainfo:eu-repo/semantics/openAccessFerreira, Jorge LuisBresolin, TiagoLopes, Fernando BritoGarcia, José Américo SoaresNepomuceno, Leandro LopesSchmidt, Aline BeatrizLobo, Raysildo Barbosa2023-06-07T18:48:26Zoai:ojs.revistas.ufg.br:article/39566Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:56:13.214464Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true
