Descrição: dc.descriptionThe aim of this work was to evaluate different models in which the random effects of litter and maternal genetic (correlated or not with the direct additive genetic effect) were added in sequence to the direct additive genetic random effect. There were on farm records of 17,563 Landrace (LD) and 8679 Large White (LW) animal. The comparison of the models and significance levels of each effect added were determined by the Likelihood Ratio test. Variance components were estimated using the Restricted Maximum Likelihood method. For LD breed the best model included the direct and maternal genetic effects, besides the litter effect. For the LW breed the best model included the direct genetic and litter effects. Heritability estimates of average daily gain, off-test age, and number of days on test were, respectively, 0.28, 0.24, and 0.24 for LD breed, and 0.28, 0.27, and 0.23 for LW breed. The litter effect was between 0.08 and 0.12 for both breeds. The maternal effect in LD breed was of small magnitude (0.01 to 0.03). Correlations between direct and maternal genetic effects were null or negative.-
