Method R Estimates of Additive Genetic, Dominance Genetic, and Permanent Environmental Fraction of Variance for Yield and Health Traits of Holsteins
TL;DR: Fractions of variance accounted for by additive genetic, dominance genetic, and permanent environmental effects for milk, fat, and protein yields; somatic cell score; and productive life were estimated from Holstein data used for national genetic evaluations.

Improvement of Prediction Ability for Genomic Selection of Dairy Cattle by Including Dominance Effects
TL;DR: For yield traits, including additive and dominance effects fit the data better than including only additive effects; average correlations between estimated genetic effects and phenotypes showed that prediction accuracy increased when both effects rather than just additive effects were included.
Bayesian models with dominance effects for genomic evaluation of quantitative traits.
Robin Wellmann,Jörn Bennewitz +1 more
TL;DR: A general hierarchical Bayesian model for genomic selection that can realistically account for dominance is introduced and several submodels are proposed and compared with respect to their ability to predict genomic BV, dominance deviations and genotypic values by stochastic simulation.

TL;DR: Assessment of additive and dominance variance components for fertility and milk production traits of genotyped Holstein and Jersey cows in Australia found that including dominance in the model was not consistently advantageous, but accuracy of prediction of phenotypes was slightly increased.

TL;DR: Estimated dominance variance was substantial for most of the analyzed traits and Exploitation of dominance variance in assortative matings was promising and did not appear to severely compromise additive genetic gain.

A simple method for computing the inverse of a numerator relationship matrix used in prediction of breeding values
TL;DR: In this article, the inverse of a numerator relationship matrix is needed for best linear unbiased prediction of breeding values, and a simple method for computing the elements of this inverse without computing the relationship matrix itself is presented.

An Extension of the Concept of Partitioning Hereditary Variance for Analysis of Covariances among Relatives When Epistasis Is Present.
TL;DR: The present paper shows the subdivision of the epistatic variance into components and gives the distribution of these epistatic components in the covariances or correlations between relatives.

The Effects of Inbreeding on the Lifetime Performance of Dairy Cattle
TL;DR: The effects of inbreeding were cumulative, and effects on lifetime profit functions were relatively larger than the effects on lactation traits, and registered cows had higher levels of in breeding and larger standard deviations than did grade cows.

TL;DR: Proper procedures were developed for animal model evaluation of dairy cattle for milk, fat, and protein yields as well as evaluation for fat and protein percentages as a function of yield evaluations.

Genetic Evaluation of Length of Productive Life Including Predicted Longevity of Live Cows
TL;DR: Inclusion of yield for projection increased heritability at 36 mo substantially but decreased genetic correlation with complete longevity information, which will allow predicted records to be used in longevity evaluations, similar to the procedures that allow predicted 305-d yields to be included in yield evaluations.
