International single-step SNPBLUP beef cattle evaluations for Limousin weaning weight.

ABSTRACT:

Background

Compared to national evaluations, international collaboration projects further improve accuracies of estimated breeding values (EBV) by building larger reference populations or performing a joint evaluation using data (or proxy of them) from different countries. Genomic selection is increasingly adopted in beef cattle, but, to date, the benefits of including genomic information in international evaluations have not been explored. Our objective was to develop an international beef cattle single-step genomic evaluation and investigate its impact on the accuracy and bias of genomic evaluations compared to current pedigree-based evaluations.

Methods

Weaning weight records were available for 331,593 animals from seven European countries. The pedigree included 519,740 a
