Disentangling the dynamics of energy allocation to develop a proxy for robustness of fattening pigs
There is a growing need to improve robustness of fattening pigs, but this trait is difficult to phenotype. Our first objective was to develop a proxy for robustness of fattening pigs by modelling the longitudi... (Source: Genetics Selection Evolution)

Approaching autozygosity in a small pedigree of Gochu Asturcelta pigs
In spite of the availability of single nucleotide polymorphism (SNP) array data, differentiation between observed homozygosity and that caused by mating between relatives (autozygosity) introduces major diffic... (Source: Genetics Selection Evolution)

Genomic prediction based on selective linkage disequilibrium pruning of low-coverage whole-genome sequence variants in a pure Duroc population
Although the accumulation of whole-genome sequencing (WGS) data has accelerated the identification of mutations underlying complex traits, its impact on the accuracy of genomic predictions is limited. Reliable... (Source: Genetics Selection Evolution)

The mRNA-lncRNA landscape of multiple tissues uncovers key regulators and molecular pathways that underlie heterosis for feed intake and efficiency in laying chickens
Heterosis is routinely exploited to improve animal performance. However, heterosis and its underlying molecular mechanism for feed intake and efficiency have been rarely explored in chickens. Feed efficiency c... (Source: Genetics Selection Evolution)

Interpreting single-step genomic evaluation as a neural network of three layers: pedigree, genotypes, and phenotypes
