Understanding host-microbiome interactions and influence on STEC colonization in cattle using integrated omics
DownloadFall 2023
Shiga toxin producing Escherichia coli (STEC) is the major foodborne pathogen in humans with Shiga toxin 1 (stx1) and 2 (stx2) being the main virulence factors. Cattle are the major reservoir of STEC with those shedding >104 CFU/g STEC being defined as super shedders (SS). The rectal anal...

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...

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...

Effect of breed type and residual feed intake on meat and collagen quality and expression of genes involved in collagen synthesis and degradation in bovine m. gluteus medius
DownloadSpring 2020
Residual feed intake (RFI) is an index of feed efficiency that has been demonstrated to be moderately heritable, with cattle having low RFI values being efficient as they consume less feed for the same weight gain. This may be of financial benefit to producers, but to be fully beneficial to...

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...

Polar bears (Ursus maritimus) were among the first large mammals to be assessed for genetic variation in the wild, and they remain a common subject of genetics studies. Although recent advances in genotyping technology have allowed for more accurate determination of population structure and the...

Spring 2016
The main objective of this research was to evaluate the potential of 3-nitrooxypropanol (NOP) to lower enteric methane (CH4) production by ruminants. Methane is an undesirable byproduct of enteric fermentation that represents a loss of energy to the animal. Additionally, CH4 is a greenhouse gas...

Identifying Gene Expression Differences Induced by Diets that Lead to Higher Omega-3 Fatty-Acid Deposition in Beef Cows
DownloadFall 2015
A strong emphasis on the type of fatty acids (FAs) consumed in the human diet has emerged in recent years. In this context, the various health benefits of consuming omega-3 (n-3) polyunsaturated fatty acids (PUFAs) have been widely reported. Supplementation of beef cattle diets with flaxseed, a...

New insights about barnacle reproduction: Spermcast mating, aerial copulation and population genetic consequences
DownloadSpring 2014
Barnacles are mostly hermaphroditic and they are believed to mate via copulation or, in a few species, by self-fertilization. However, isolated individuals of two species that are thought not to self-fertilize, Pollicipes polymerus and Balanus glandula, nonetheless carried fertilized...

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...
