“…For conventional multistep genetic evaluations, the drawbacks for instance of biased or inaccurate predictions for genotyped animals, the absence of gain in accuracy for ungenotyped animals, and incompatibility between EBVs for genotyped and ungenotyped animals (Bermann et al, 2022), undermine the prediction performance of the multiple-step method and may yield lower accuracy compared with ssGBLUP that includes both genotyped and ungenotyped animals simultaneously in a single genetic evaluation. In this study, we improved the prediction performance of the multistep method with Absorption approach, which achieved similar accuracy as ssGBLUP and in general lower bias.…”

“…With extensive research and the development of efficient computing algorithms to solve the challenges that limit the practical implementation of ssGBLUP, for instance metafounder approach (Kudinov et al, 2020; Legarra et al, 2015) and the use of the J factor (Belay et al, 2022; Stranden et al, 2022) to improve the compatibility between genomic and pedigree information, ssGBLUP has become the most popular methodology for genetic evaluations including genotyped and ungenotyped animals and has been successfully implemented in almost all livestock populations (Bermann et al, 2022). However, even though ssGBLUP took over the multistep method as the most chosen genetic evaluation methodology, the multistep method may show merits for instance the more straightforward extension of the method to variable selection models.…”

“…Genomic information is valuable for selecting low‐heritability traits and is widely employed in animal breeding programs. Currently, the single‐step genomic best linear unbiased prediction (ssGBLUP) is the most popular method for genetic evaluations of populations with both genotyped and non‐genotyped animals (Bermann et al, 2022).…”

“…This is two-step procedure. Recently, single-step genomic BLUP combining information on both genotyped and non-genotyped animals is widely implemented (Lourenco et al, 2020;Mäntysaari et al, 2020;Bermann et al, 2022).…”
