Resumo: | The aim of this study was to verify the existence of interaction between age of dam effect and month of birth effect on weaning weight with the studied regions. Records of 333,259 Nelore animals from Brazilian Association of Zebu Breeds (ABCZ) were analysed. The analysis was carried out using the least squares method. Effects of year of birth, sex, farm and interactions between month of birth and region, and age of dam and region were considered. All effects included in the model affected significantly weaning weight. The Northwest, Center-west, Southeast and South regions were compared using Conditional Residual Model to verify differences on month of birth effect and age of dam effect. For all regions, month of birth effect and age of dam effect on weaning weight were statistically significant (P<0,01). The interaction between age of dam and region, and month of birth and region are an important source of variation on weaning weight. To increase the income and to facilitate the handling, breeding seasons should be established for each region. |

Foram analisados dados de 333.259 animais da raça Nelore, provenientes da Associação Brasileira de Criadores de Zebu (ABCZ). As análises foram realizadas usando-se a metodologia de quadrados mínimos. Foram considerados os efeitos de ano de nascimento, sexo, fazenda e as interações do efeito da idade da vaca e mês de nascimento com a região. Todos os efeitos incluídos no modelo afetaram significativamente o peso à desmama. Utilizando o método do Modelo do Resíduo Condicional, as regiões Nordeste, Centro-Oeste, Sudeste e Sul, foram comparadas duas a duas para verificar diferenças dos efeitos da idade da vaca ao parto e do mês de nascimento entre elas. Para todas as regiões o efeito da idade da vaca e do mês de nascimento sobre o peso ao desmame foi significativamente diferente (p<0,01). As interações dos efeitos estudados e região são importantes fontes de variação para o peso à desmama. Para aumentar o rendimento e facilitar o manejo, estações de monta devem ser estabelecidas para cada região.Editora da Universidade Estadual de Maringá2008-04-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/172410.4025/actascianimsci.v26i4.1724Acta Scientiarum.
