Genomic evaluation has been successfully implemented in the United States, Canada,
Great Britain, Ireland, New Zealand, Australia, France, the Netherlands, Germany, and the …

A new technology called genomic selection is revolutionizing dairy cattle breeding. Genomic
selection refers to selection decisions based on genomic breeding values (GEBV). The …

Selection indexes have been extensively applied in the estimation of breeding value of dairy
cattle for single traits as well as for combinations of traits for selection purposes. Milestones …

Genetic parameters were estimated using relationships between animals that were based
either on pedigree, 43,011 single nucleotide polymorphisms, or a combination of these …

During the last decade, genomic selection has revolutionized dairy cattle breeding. For
example, Nordic dairy cows (Denmark, Finland, and Sweden) born in 2018 were> 90% sired …

Test-day traits are important for genetic evaluation in dairy cattle and are better modeled by
multiple-trait random regression models (RRM). The reliability and bias of genomic …

The objectives of this study were to investigate bias in genomic predictions for dairy cattle
and to find a practical approach to reduce the bias. The simulated data included …

Substantial increases of 3,500 kg of milk, 130kg of fat, and 100kg of protein per cow per
lactation have resulted from improvements in genetics, nutrition, and management during …

A genomic preselection step of young sires is now often included in dairy cattle breeding
schemes. Young sires are selected based on their genomic breeding values. They have …

The purpose of this study was to evaluate the accuracy of genomic selection in single-step
genomic BLUP (ssGBLUP) when the inverse of the genomic relationship matrix (G) is …
