Resumo: | The objective of this work was to evaluate the temperament of Canchim calves using different methods, to compare these methods, and to determine the most suitable for commercial use. The temperament of 1,831 calves was evaluated at 15 days after weaning by visually analyzing movement, tension, breathing, vocalizing, and kicking. Measurements were taken at 10 and 20 s after the calf entered the scale. The reactivity score was determined electronically, and flight speed was measured after the calf left the scale. The results of the principal component analysis showed that the first component explained 40.27% of total variation. Positive correlations were found for tension at 10 and 20 s, movement at 10 and 20 s, and reactivity score, with correlation coefficients ranging from 0.60 to 0.88. Temperament and reactivity scores presented moderate correlations of 0.25 and 0.35, respectively, with flight speed. However, kicking had no correlation with any variable. No differences were observed for reactivity measured at 10 or 20 s. The visual evaluations of movement and tension or of reactivity through an electronic device can be used for temperament evaluation of Canchim calves. |

O temperamento de 1.831 bezerros foi avaliado 15 dias após a desmama, tendo-se analisado visualmente deslocamento, tensão, respiração, vocalização e coice. As medidas foram feitas aos 10 e 20 s após o bezerro entrar na balança. A reatividade foi determinada eletronicamente, e a velocidade de saída foi medida após o bezerro sair da balança. O resultado da análise de componentes principais indicou que o primeiro componente explicou 40,27% da variação total. Foram verificadas correlações positivas para tensão aos 10 e 20 s, deslocamento aos 10 e 20 s, e reatividade, com coeficientes de correlação de 0,60 a 0,88. Os escores de temperamento e reatividade apresentaram correlação moderada de 0,25 e 0,35, respectivamente, com velocidade de saída. No entanto, coice não se correlacionou com nenhuma variável. Não foi observada nenhuma diferença para reatividade medida aos 10 ou 20 s. As avaliações visuais de deslocamento e tensão ou da reatividade por dispositivo eletrônico podem ser utilizadas na avaliação de temperamento de bezerros Canchim.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraEmpresa Brasileira de Pesquisa Agropecuária (Embrapa)Marcondes, Cintia RighettiSouza, Vanessa Aparecida Feijó deBugner, Ana Luisa PaçóOliveira, Fábio da RozaMaffei, Walsiara EstanislauRibeiro, Andrea Roberto Bueno2023-12-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/27526Pesquisa Agropecuaria Brasileira; V.58, Jan./Dec., 2023: Publicação contínua em volume anual; e03350Pesquisa Agropecuária Brasileira; V.58, Jan./Dec., 2023: Publicação contínua em volume anual; e033501678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/27526/15260Direitos autorais 2023 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2023-12-14T19:05:00Zoai:ojs.seer.sct.embrapa.br:article/27526Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2023-12-14T19:05Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
