Table 3 Additive genetic parameters and heritabilities. Additive genetic parameters for the four traits are computed from model parameter estimates in Table 2 in Christensen et al. [1]. Concerning parameters \(\sigma_{g,p}^{2}\) and \(h_{p}^{2}\), we refer to Table 3 in Christensen et al. [1]. Variance for crossbred performance: \(\sigma_{g,c}^{2}\) computed using Eq. (8), covariance between purebred and crossbred performances: \(\sigma_{g,pc}\) computed using Eq. (9), correlation between purebred and crossbred performances: \(\rho_{g,pc}\), and heritability \(h_{c}^{2} = \sigma_{g,c}^{2} /(\sigma_{a,c}^{2} \overline{\delta G}_{c} \sigma_{d,c}^{2} + \overline{\delta D}_{c} \sigma_{l,c}^{2} + \sigma_{e,c}^{2} ),\)where \(\overline{\delta G}_{c}\) and \(\overline{\delta D}_{c}\) are averages of diagonal elements in matrices \({\mathbf{G}}_{c}\) and \({\mathbf{D}}_{c}\) in Christensen et al. [1], respectively. BF: ultra-sound recorded backfat thickness, CONF: overall conformation score, ADG: average daily gain, FCR: feed conversion ratio
