Application of manure from cattle fed with different diets affects soil properties and greenhouse gas emissions
DownloadSpring 2019
Cattle production contributes the largest portion of livestock agricultural greenhouse gas (GHG) emissions in Canada mostly in the form of methane (CH4). Efforts to reduce CH4 emissions have led to modification of diet composition for livestock, resulting in a corresponding change in manure...

Investigation of Causal Mutations in Livestock and Companion Animals Using Whole-Genome Sequencing (WGS) and Bioinformatics
DownloadSpring 2024
In this thesis project, three studies were conducted, aimed at identifying the causal variants responsible for phenotypic/genotypic sex discordance in cattle, copper toxicosis in Dalmatian dogs, and low fertility/infertility in cattle. In all three studies, whole-genome sequencing (WGS) and...
