Social genetic effects for growth in pigs differ between boars and gilts

Table 4 Pearson correlations (standard errors in brackets) of predicted breeding values and corrected phenotypes for the univariate and the bivariate model based on 431 boars and 876 gilts

\(DBV_{{CLASSIC_{i} }}\) = direct breeding value for individual i from the classical model
\(DBV_{{SOCIAL_{i} }}\) = direct breeding value from individual i from the social genetic model
\(\sum SBV_{{SOCIAL_{j} }}\) = sum of the social breeding values of mates j
\(P_{{TOTAL_{i} }}\) = total phenotype of an individual calculated as: \(P_{{TOTAL_{i} }} = DBV_{{SOCIAL_{i} }} + \sum SBV_{{SOCIAL_{j} }}\)
^aCorrected phenotypes from univariate (u) and bivariate (b) models, respectively
^bP value tests if the correlation between the corrected phenotypes and \(DBV_{{CLASSIC_{i} }}\) is statistically different from the correlation between the corrected phenotypes and \(P_{{TOTAL_{i} }}\)
