摘要: In this study, we have demonstrated that using dry matter intake (DMI) phenotypes from multiple countries increases the accuracy of genomic breeding values for important trait, provided a multi-trait approach is used. Data Australia, Canada, Denmark, Germany, Ireland, Netherlands, New Zealand, United Kingdom and two institutions in States were combined to estimate prediction DMI models. The average accuracies was 0.44, ranged 0.37 (Denmark) 0.54 (the Netherlands). Enlarging dataset with unique does increase DMI. This stimulates further international collaboration.
