Fall 2010
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,...

CANDIDATE GENES, METABOLITES AND BIOLOGICAL PATHWAYS ASSOCIATED WITH RESIDUAL FEED INTAKE AND CARCASS QUALITY IN BEEF CATTLE
DownloadFall 2013
The main objective of this study was to identify genes, DNA variants and plasma metabolites associated with residual feed intake (RFI) in beef cattle. In the first study, a total of 117 SNPs were selected and genotyped in 531 steers at the University of Alberta. The population was split into a...

Genetics of feed efficiency and feeding behavior in crossbred beef steers with emphasis on genotype-by-environment interactions
DownloadFall 2011
This study examined whether crossbred steers had different production, feed efficiency and feeding behavior performances when they were fed a grower or finisher diet or both, in successive feeding periods. Major feed efficiency traits were residual feed intake (RFI) and gain to feed ratio (G:F)...

Fall 2010
A whole genome scan was conducted to identify and fine map QTL regions for ultrasound and carcass merit traits in beef cattle. A total of 465 steers and bulls, genotyped for 4592 SNPs, were analysed for 16 ultrasound and carcass merit traits using interval mapping, single marker regression and...
