Genetic correlations between days to first calving and scrotal circumference and weight at 12 months of age in a Canchim beef cattle herd



Genetic correlations between days to first calving and scrotal circumference and weight at 12 months of age in a Canchim beef cattle herd



Proceedings of the 8th World Congress on Genetics Applied to Livestock Production, Belo Horizonte, Minas Gerais, Brazil, 13-18 August, 2006: 03-65



The objective of this study was to estimate the genetic correlation of days to first calving (DFC) with scrotal circumference (SC) and body weight (BW) at 12 months of age, in a Canchim beef cattle herd. Analyses of DFC were done with (DFCP) and without (DFC) the females which did not conceive during the breeding season, using REML. The statistical models included fixed effects and additive direct random effect for all traits, and maternal permanent environment random effect for SC and BW.
