Spring 2012
Climate change is expected to drive major changes in agricultural production around the world, but estimates of the economic impact of these changes for Canadian agricultural production have been inconsistent. Most models use aggregate temperature data such as average temperature or growing...

Application of Multi-Omics Tools to Study the Genetic Background of Economically Relevant Traits in Commercial Beef Production
DownloadSpring 2022
The sustainability and profitability of beef cattle production are largely associated with feed efficiency, carcass merit, and resistance to infectious diseases. These traits are difficult or expensive to measure on individual animals, which makes them suitable for genomic application. Currently...

Association analyses of SNPs in candidate genes with body fat deposition and carcass merit traits in beef cattle
DownloadFall 2009
A candidate gene approach was used to identify single nucleotide polymorphisms (SNPs) and their associations with body fat deposition and carcass merit traits in beef cattle. In total, 37 SNPs from 9 candidate genes have been genotyped on 463 hybrid, 206 Angus and 187 Charolais steers for...

Fall 2011
Feed efficiency affects profitability and sustainability in beef production systems. Since ruminal microbes play essential roles in feed digestion and conversion, the overall objective of this project was to investigate the association between ruminal bacteria and feed efficiency of beef cattle....

Contribution of the Rumen Epithelial Transcriptome and Microbial Community to Variation in Beef Cattle Feed Efficiency
DownloadSpring 2016
Feed efficient cattle consume less feed and produce less environmental waste than inefficient cattle. Many factors are known to contribute to differences in feed efficiency. However, it is unknown how the rumen epithelium and its associated microorganisms influence the feed efficiency of cattle....

Effect of dried distillers’ grains with solubles on greenhouse gas emissions from beef cattle
DownloadSpring 2014
Four experiments were conducted to determine the impact of dried distillers’ grains with solubles (DDGS) on greenhouse gas (GHG) emissions from beef cattle. The first compared in vitro methane (CH4) production from corn DDGS (CDDGS, ~30% crude protein [CP]) and wheat DDGS (WDDGS, ~40% CP dry...

Evolutionary quantitative genetics and genomics applied to the study of sexually dimorphic traits in wild bighorn sheep (Ovis canadensis)
DownloadSpring 2011
The independent evolution of the sexes may often be constrained if male and female homologous traits share a similar genetic architecture. Thus, cross-sex genetic covariance is assumed to play a key role in the evolution of sexual dimorphism (SD) with consequent impacts on sexual selection,...

Fall 2009
Bovine Spongiform Encephalopathy (BSE) belongs to a group of neurodegenerative diseases known as transmissible spongiform encephalopathies (TSEs) which affect many species. From 1986 more than 184,000 cattle in the UK have been confirmed to be infected with this disease, and in Canada total...
