Estimation of genetic parameters for weaning and yearling weights in a composite population used to form the Purunã breed

ABSTRACT We aimed to evaluate the effects of sex and the linear and quadratic components of age of dam at calving, as well as apply a mixed model including maternal effect for the genetic evaluation of weaning (WW) and yearling (YW) weights. The phenotypic database was composed by Charolais, Caracu,...
