An alternative interpretation of residual feed intake by phenotypic recursive relationships in dairy cattle

open access: yesJDS Communications, 2021
There has been increasing interest in residual feed intake (RFI) as a measure of net feed efficiency in dairy cattle. Residual feed intake phenotypes are obtained as residuals from linear regression encompassing relevant factors (i.e., energy sinks) to ...

SNP Data Quality Control in a National Beef and Dairy Cattle System and Highly Accurate SNP Based Parentage Verification and Identification

open access: yesFrontiers in Genetics, 2018
A major use of genetic data is parentage verification and identification as inaccurate pedigrees negatively affect genetic gain. Since 2012 the international standard for single nucleotide polymorphism (SNP) verification in Bos taurus cattle has been the

On the Breeds of Cattle—Historic and Current Classifications [PDF]

open access: yesDiversity, 2011
Classification of cattle breeds contributes to our understanding of the history of cattle and is essential for an effective conservation of genetic diversity. Here we review the various classifications over the last two centuries and compare the most recent classifications with genetic data.

Genetic benefits of genomic selection breeding programmes considering foreign sire contributions

open access: yesGenetics Selection Evolution, 2019
Background In modern dairy breeding programmes, high contributions from foreign sires are nearly always present. Genotyping, and therefore genomic selection (GS), concern only a subpopulation of the breeding programme’s wider dairy population.
