Fall 2014
Quantification of important biochemical (e.g. intramuscular fat content, toughness) properties of beef m. longissimus thorasis (LT) using technologies of optical spectroscopy and digital image analysis was examined in this thesis research. The main objective of this thesis work focused on the...

Application of antimicrobials for the elimination of Escherichia coli and Listeria monocytogenes in brine injected beef
DownloadFall 2013
The application of antimicrobials to a brine-injected raw beef roast for the elimination/inhibition of heat resistant Escherichia coli and Listeria monocytogenes was investigated. The choice of antimicrobials for use in brine injected beef was based on minimum bactericidal concentration in brine...

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,...

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...

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...

Spring 2021
Approximately 70% of the cost of beef production is impacted by dietary intake. Maximizing production efficiency of beef cattle requires not only genetic selection to maximize feed efficiency (i.e. residual feed intake - RFI), but also adequate nutrition throughout all stages of growth and...

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...

Characterization of Heat Resistant Escherichia coli Isolates Associated with Human Infection
DownloadSpring 2021
Shiga toxin-producing Escherichia coli (STEC) is a bacterial pathogen associated with foodborne diarrheal disease. Infection with STEC presents as a mild, watery diarrhea to hemorrhagic colitis and can progress to the life-threatening complication, hemolytic uremic syndrome. Cattle are recognized...

Design and Demonstration of a High Throughput DNA Tracking System for Genetic Improvement and Brand Verification in the Canadian Beef Industry
DownloadSpring 2014
The Canadian beef industry today is challenged to adapt to climate change and to produce quality beef more efficiently, using fewer resources and with less impact to the environment. Competing protein sources have integrated their supply chains and applied genetic selection to increase...
