  1. 1TBV t600, Φ 1 , Φ 2 and Φ 2 : true breeding values for t600, and parameters Φ 1 , Φ 2 , Φ 2 from the logistic growth curve. GEBV t600_I, t600_II, A, B and C: genomic breeding values for t600 estimated with method I and II and for parameters A, B and C from the Gompertz curve. Correlations are for all animals.
  2. 2The results shown here are higher than those presented to the QTLMAS workshop since an error in the implementation was found afterwards. Values presented at the workshop were 0.907 and 0.911 for the Pearson correlations of method I and II, and 0.886 and 0.891 for the Spearman correlations for methods I and II.
