Resumo: | The objective of this study was to evaluate the effect of the genetic component on the phenotypic expression of productive traits of Nellore cattle submitted to the individual performance test. The data used came from 51 young bulls participating in the individual performance test of Nellore bulls held at the Capim Branco experimental farm of the Federal University of Uberlândia. The evaluated traits were weight and scrotal circumference standardized at 365 and at 450 days of age, the longissimus muscle area, and the backfat thickness. The expected progeny differences of the animals and the sires were considered to evaluate the contribution of the genetic component. Variance analysis was performed through the General Linear Model procedure of the Statistical Analysis System to verify the effects of the genetic groups on the productive performance. The progenies of bulls with greater genetic potential tend to present better productive performance. In conclusion, the use of genetically superior animals allows better zootechnical indexes to be obtained, reflecting higher gains in herd productivity.Keywords: beef cattle; breeding value; productivity, selection. |

Os dados utilizados foram provenientes de 51 touros jovens participantes da Prova de Desempenho Individual de Touros Nelore realizada na fazenda experimental Capim Branco da Universidade Federal de Uberlândia. As características avaliadas foram peso e perímetro escrotal padronizado aos 365 e aos 450 dias de idade, área de olho de lombo e acabamento de carcaça. Com o intuito de avaliar a contribuição do componente genético no desempenho produtivo dos animais foram consideradas as predições das diferenças esperadas na progênie dos animais e dos touros (pais dos animais). Para verificar os efeitos dos grupos genéticos sobre o desempenho produtivo foram realizadas análises de variância por meio do procedimento General Linear Model do aplicativo Statistical Analysis System. Verificou-se que os filhos de touros com maior potencial genético tendem a apresentar melhor desempenho produtivo. Concluiu-se que o uso de animais geneticamente superiores permite a obtenção de melhores índices zootécnicos refletindo em maiores ganhos em produtividade do rebanho.Palavras-chave: Bovinos de corte; produtividade; seleção; valor genético.Universidade Federal de Goiás2017-03-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa CientíficaResearchapplication/pdftext/htmlapplication/pdfhttps://revistas.ufg.br/vet/article/view/e-3052810.1590/cab18030528Brazilian 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:UFGporenghttps://revistas.ufg.br/vet/article/view/e-30528/22529https://revistas.ufg.br/vet/article/view/e-30528/22531https://revistas.ufg.br/vet/article/view/e-30528/22558Faria, Carina UbirajaraPereira, Cristiane de Fátimada Silva, Rosiane PereiraPessoa, Denis DouglasMagnabosco, Cláudio UlhôaLôbo, Raysildo Barbosainfo:eu-repo/semantics/openAccess2023-06-07T18:48:26Zoai:ojs.revistas.ufg.br:article/30528Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:56:05.755743Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
