HSSGBLUP: a single-step SNP-BLUP genomic evaluation software adapted to large livestock populations.

Abstract : In France, current dairy and beef cattle genomic evaluations are based on multi-step approaches. Preselection of genotyped animals generates biased estimated breeding values and genetic trends. Single Step GBLUP evaluations are being implemented to solve this issue, with the development of a software fitting the French bovine evaluations requirements: - Large populations (up to 20 million animals) - Hundreds of thousands of informative genotyped animals - Genetic Groups - Multiple traits evaluations, possibly with maternal genetic effects and heterogeneous variances - Inclusion of effects of QTL or causal variants - Inclusion of foreign phenotypic information for international populations (Holstein, BSW)
