"The investigation was based on a data set from six pig sire breeds with 11039 station-tested purebred, 65313 field-tested purebred and 17004 field-tested crossbred animals. Four four-trait animal models were studied: (i) without crossbred information, without genetic groups (cb-gg), (ii) with crossbred information, without genetic groups (CB-gg), (iii) without crossbred information, with genetic groups (cb-GG), (iv) with crossbred information and with genetic groups (CB-GG). The total breeding value (TB value (TBV) was calculated from daily gain on field and valuable cuts on station. For comparing the prediction accuracy of the different models, the mean square root of the prediction error variance was expressed in standard deviations of the distribution of predicted breeding values. The model cb-GG was the best one. The introduction of genetic groups in the basic model cb-gg had a greater impact on ranking boars than the introduction of crossbred information."@en .
