Advanced agronomic practices to maximize feed barley (Hordeum vulgare L.) yield, quality, and standability in Alberta environments
DownloadFall 2017
The grain yields of feed barley (Hordeum vulgare L.) have increased at a slower rate than the yields of other major crops in Alberta, and seeded barley acres have declined over the past 20 years. Agronomic management and cultivar specific responses to management may provide solutions to increase...

Assessment of rumen microbiota in beef heifers with different feed efficiency and managed under different feeding systems
DownloadSpring 2020
The linkage between rumen microbiota and feed efficiency has been studied in cattle managed under the drylot system, especially in the feedlot with high-grain diets. However, pasture-based beef operations still dominate the beef production system around the world. In Alberta and other provinces...

Fall 2021
Disease resilience is defined as an animal’s ability to maintain a high level of performance in the face of disease challenges caused by multiple pathogens, as is often the case in commercial pig farms. Therefore, disease resilience is anticipated to be critical to the profitability of the pig...

Fall 2021
Clubroot disease, caused by Plasmodiophora brassicae, is a major threat to canola production. Cultivation of resistant cultivars is the key component in managing this disease. Canola is an important oilseed crop in the world; this includes the allopolyploid species Brassica napus L. (AACC genome,...

Manipulation of Seed Carbon Flow from Cellulose to Lipid and Protein Biosynthesis in Arabidopsis to Accelerate the Characterization of Protein-Related Genes in Canola
DownloadFall 2023
Canola (Brassica napus L.) is the major oilseed crop in Canada. After oil extraction, the protein-rich seed meal (around 40% protein) serves as a nutritious feedstock for animals and the protein fraction has potential for human consumption. However, excess fiber in the seed meal (about 33%) can...

Novel feed enzyme delivery method: Binding exogenous feed enzymes to Bacillus spores to improve enzyme stability and total tract digestibility
DownloadFall 2018
The effects of binding feed enzymes to Bacillus subtilis (strain RK28) spores on enzyme stability and digestion in cattle were studied in comparison to unbound enzymes. Optimal conditions for adsorbing six different enzymes (α-amylase, β-glucanase, feruloyl esterase, phytase, purified xylanase,...

Patterns of Genomic Variation and Whole Genome Association Studies of Economically Important Traits in Cattle
DownloadFall 2012
Functionally important genetic variations in cattle have great potential as tools to increase agricultural production once they are identified through association studies of phenotype and genotype. The objectives of this thesis were: 1) to characterize the genome-wide patterns of linkage...

Performance and Methane Emissions of RFI Selected Cattle in Drylot and Under Open Range Conditions
DownloadSpring 2018
Residual feed intake (RFI) is a moderately heritable trait that can be used to measure feed efficiency in beef cattle, and thereby reduce feed related costs. RFI has been primarily evaluated under drylot conditions where diet, feed intake and activity levels are controlled and foraging behaviour...
