Disentangling the dynamics of energy allocation to develop a proxy for robustness of fattening pigs
CONCLUSIONS: Results of this study show that selection for robustness, based on estimated breeding values for environmental variance of the allocation coefficients to growth, can be considered in breeding programs for fattening pigs.PMID:37936078 | DOI:10.1186/s12711-023-00851-w (Source: Genet Sel Evol)

Across-country genetic and genomic analyses of foot score traits in American and Australian Angus cattle
CONCLUSIONS: This study presents comprehensive population structure and genetic and genomic analyses of foot scores in US and AU Angus cattle populations, which are essential for optimizing the implementation of genomic selection for improved foot scores in Angus cattle breeding programs. We have also identified candidate genes associated with foot scores in the largest Angus cattle populations in the world and made recommendations for genomic evaluations for improved foot score traits in the US and AU.PMID:37919645 | PMC:PMC10621155 | DOI:10.1186/s12711-023-00850-x (Source: Genet Sel Evol)

Approaching autozygosity in a small pedigree of Gochu Asturcelta pigs
CONCLUSIONS: Parameters characterizing homozygosity may not accurately depict losses of variability in small populations in which breeding policy prohibits matings between close relatives. After BP adjustment, the performance of FROH and FHRR was highly consistent. Assuming that an increase in homozygosity depends only on pedigree depth can lead to underestimating it in populations with shallow pedigrees. An increase in pairwise homozygosity computed from either FROH or FHRR is a promising approach for characterizing autozygosity.PMID:37880572 | PMC:PMC10601182 | DOI:10.1186/s12711-023-00846-7 (Source: Genet Sel Evol)

Combined single-step evaluation of functional longevity of dairy cows including correlated traits
CONCLUSIONS: A CSS evaluation is an efficient tool to improve FL. It allows a proper combination of information on functional traits that influence culling. In contrast, because of the strong selection intensity on young bulls for functional traits, the benefit of such a "combined" evaluation of functional traits is more modest for these males.PMID:37880580 | PMC:PMC10601146 | DOI:10.1186/s12711-023-00839-6 (Source: Genet Sel Evol)
