Open AccessImproving selection decisions with mating information by accounting for Mendelian sampling variances looking two generations ahead
Breeding programs are judged by the genetic level of animals that are used to disseminate genetic progress. These animals are typically the best ones of the population. To maximise the genetic level of very go...

Open AccessIntegration of beef cattle international pedigree and genomic estimated breeding values into national evaluations, with an application to the Italian Limousin population
International evaluations combine data from different countries allowing breeders to have access to larger panels of elite bulls and to increase the accuracy of estimated breeding values (EBV). However, intern...

Open AccessEfficient large-scale single-step evaluations and indirect genomic prediction of genotyped selection candidates
Single-step genomic best linear unbiased prediction (ssGBLUP) models allow the combination of genomic, pedigree, and phenotypic data into a single model, which is computationally challenging for large genotype...

Open AccessInternational single-step SNPBLUP beef cattle evaluations for Limousin weaning weight
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 us...

Open AccessImpact of genomic preselection on subsequent genetic evaluations with ssGBLUP using real data from pigs
Empirically assessing the impact of preselection on genetic evaluation of preselected animals requires comparing scenarios that take different approaches into account, including scenarios without preselection....

Open AccessInvestigating the impact of preselection on subsequent single-step genomic BLUP evaluation of preselected animals
Preselection of candidates, hereafter referred to as preselection, is a common practice in breeding programs. Preselection can cause bias and accuracy loss in subsequent pedigree-based best linear unbiased pre...

Open AccessImpact of sub-setting the data of the main Limousin beef cattle population on the estimates of across-country genetic correlations
Cattle international genetic evaluations allow the comparison of estimated breeding values (EBV) across different environments, i.e. countries. For international evaluations, across-country genetic correlations (

Open AccessEffects of alleles in crossbred pigs estimated for genomic prediction depend on their breed-of-origin
This study investigated if the allele effect of a given single nucleotide polymorphism (SNP) for crossbred performance in pigs estimated in a genomic prediction model differs depending on its breed-of-origin, ...

Open AccessGenomic prediction based on data from three layer lines: a comparison between linear methods
The prediction accuracy of several linear genomic prediction models, which have previously been used for within-line genomic prediction, was evaluated for multi-line genomic prediction.
