Variance components (VC) for milk yield of Holstein cows were estimated and the effects of increasing of the number of animals in the numerator relationship matrix (NRM) were evaluated on VC estimates obtained by REML and Bayesian inference via Gibbs sampling (GS). Data were obtained from herds in the states of Minas Gerais, São Paulo, Paraná, Santa Catarina, and Rio Grande do Sul. Two data sets were created for each state. In the first set, the NRM included only the […]
