Genome-Wide Analysis of the World's Sheep Breeds Reveals High Levels of Historic Mixture and Strong Recent Selection
Genomic structure in a global collection of domesticated sheep reveals a history of artificial selection for horn loss and traits relating to pigmentation, reproduction, and body size.
Genome-Wide Survey of SNP Variation Uncovers the Genetic Structure of Cattle Breeds
Data show that cattle have undergone a rapid recent decrease in effective population size from a very large ancestral population, possibly due to bottlenecks associated with domestication, selection, and breed formation. Expand

Using whole-genome association, it is found that DNA variants in or near proteins contributing to the background use of energy of the cell were 10 times as common as those affecting appetite and body-mass homeostasis and suggests that certain subsets of micro-RNA are more important for the regulation of this trait.

A genetic linkage map of the bovine genome
A cattle genetic linkage map was constructed which marks about 90% of the expected length of the cattle genome and shows as many differences in gene order compared to humans as is found between humans and mice. Expand
Genome-wide association studies for feedlot and growth traits in cattle.
The aims were to discover SNP associated with all traits studied, but especially RFI, and further to test the consistency of SNP effects across different cattle populations and breed types, which showed consistent between data sets only when estimated within the same breed type. Expand
Characterization of 65 bovine microsatellites
Thirty of the bovine-derived microsatellite systems gave specific and polymorphic products in sheep, adding to the number of useful markers in that species. Expand
Accuracy of prediction of genomic breeding values for residual feed intake and carcass and meat quality traits in Bos taurus, Bos indicus, and composite beef cattle.
Although accuracies of genomic predictions for 19 traits including feed efficiency, growth, and carcass and meat quality traits in beef cattle are low, genomic selection would still be beneficial for traits that are hard to improve by conventional selection, such as tenderness and residual feed intake.

Chromosomal localization of the ovine callipyge locus is the first step toward positional cloning of the corresponding gene in Bovidae. Expand
A panel of polymorphic bovine, ovine and caprine microsatellite markers.
This study identified a set of 18 robust markers that were polymorphic in all three species and that covered 14 bovine chromosomes, which provides a single group of markers which would be suited to genetic distance analysis and parentage control in cattle, sheep and goat. Expand

The signals of selection identified through population divergence in the Bovine HapMap project are compared to those found in an independent sample of cattle from Australia, finding 12 regions that had additive effects on the traits residual feed intake, beef yield or intramuscular fatness measured in the Australian sample.
