Farm animal genetic diversity is required to meet current production needs in various
environments, to allow sustained genetic improvement, and to facilitate rapid adaptation to …

Inbreeding depression is a growing concern in livestock because it can detrimentally affect
animal fitness, health, and production levels. Genomic information can be used to more …

Background Levels of inbreeding in cattle populations have increased in the past due to the
use of a limited number of bulls for artificial insemination. High levels of inbreeding lead to …

The intensive selection programs for milk made possible by mass artificial insemination
increased the similarity among the genomes of North American (NA) Holsteins tremendously …

Background Recent developments in sequencing technology have facilitated widespread
investigations of genomic variants, including continuous stretches of homozygous genomic …

Background Runs of homozygosity (ROH) are continuous homozygous segments of the
DNA sequence. They have been applied to quantify individual autozygosity and used as a …

The effects of inbreeding on the lifetime performance of dairy cattle were examined using
data for production, somatic cell score, and linear type for all Holstein cows that were scored …

Background Phenotypic performances of livestock animals decline with increasing levels of
inbreeding, however, the noticeable decline known as inbreeding depression, may not be …

The objective of this study was to determine the effect of inbreeding on milk production,
somatic cell count, fertility, survival, calving performance, and cow conformation in Irish …

The objective of this study was to determine the inbreeding levels and to analyze the
pedigree of Irish purebred populations of Charolais, Limousin, Hereford, Angus, and …
