Improving feed efficiency has become a top priority in beef cattle production because of the rapidly increasing cost of feed provision. However, because of the expense associated with collecting individual animal feed intake data, only a relatively small number of animals have been tested,...

Application of genomics-based tools leading to the identification of markers on bovine chromosome 14 influencing milk production and carcass quality traits
DownloadFall 2009
Genetic improvements in beef and dairy cattle can bring significant advances in satisfying the global food demand, which is expected to double by 2050. Several DNA markers have been identified on bovine chromosome 14 (BTA14), but low mapping resolution prevents their refinement for identification...

Fine scale mapping and association study of economically important traits on chromosomes 19 and 29 in beef and dairy cattle

The objective of this thesis was to construct radiation hybrid (RH) maps and estimate linkage disequilibrium (LD) using high density SNP markers on chromosomes 19 (BTA19) and 29 (BTA29) and use these as a tool to detect QTL in dairy and beef cattle. We have constructed RH maps of BTA19 and BTA29...
