The Effect of Preselection on the Level of Bias and Accuracy in a Broiler Breeder Population, a Simulation Study

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Many breeding programmes have to perform preselection, as genotyping and phenotyping all potential breeder candidates is often not a feasible option. There is need to understand how preselection affects the quality of the genomic estimated breeding values (EBVs) at final selection and thereby can affect genetic progress.

Practical Considerations When Using Mendelian Sampling Variances for Selection Decisions in Genomic Selection Programs

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The purpose of this work was to test the application of selection criteria that consider the genetic variances of future generations. This has not been done previously in numerically large livestock breeding programs based on estimated rather than assumed known marker effects.

Genomic Diversity of U.S. Katahdin Hair Sheep

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In the late 1950s, Katahdin hair sheep were developed as a composite breed of medium size and moderate prolificacy, with potential to express resistance to gastrointestinal nematodes. With increasing popularity and the recent adoption of genomic prediction in their genetic evaluation, there is a risk of decreasing variation with selection ...

Multiple Trait Bayesian Analysis of Partitioned Genetic Trends Accounting for Uncertainty in Genetic Parameters. An Example With the Pirenaica and Rubia Gallega Beef Cattle Breeds

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Genetic trends are a valuable tool for analysing the efficiency of breeding programs. They are calculated by averaging the predicted breeding values for all individuals born within a specific time period. Moreover, partitioned genetic trends allow dissecting the contributions of several selection paths to overall genetic progress. These trends

A Similarity Matrix for Preserving Haplotype Diversity Amongst Parents in Genomic Selection

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In genomic selection, balancing genetic gain with the preservation of genetic diversity is a critical challenge, requiring innovative approaches to parent selection. Traditional methods risk losing valuable genetic diversity by not fully accounting for the complex patterns of haplotype distribution.
