Glucosamine (GlcN) is an amino monosaccharide that is widely used as a food supplement in the treatment of osteoarthritis (OA). In vitro and animal studies strongly support the therapeutic efficacy of the compound; however, clinical reports and meta-analysis are inconclusive. As compared to the...
Effect of source and concentration of supplemental trace minerals on apparent absorption and retention, performance and physiological indicators of trace mineral status in lactating Holstein dairy cowsDownload
Inorganic sources of trace minerals are commonly supplemented in dairy cow diets; however, there has been an increase in the supplementation of minerals complexed with organic compounds. Organic sources of trace minerals are thought to be protected from antagonistic interactions within the...
In view of the increasing environmental concerns about the current water-based bitumen extraction process, there have been numerous efforts to develop a non-aqueous extraction (NAE) method for the recovery of bitumen from oil sands. The research reported in this thesis was carried out to study...
Fast ignition (FI) decouples the compression and ignition in normal Inertial Confinement Fusion schemes, and can rely on hot electron transport to ignite the compressed core. In order to study electron transport, characteristic K-alpha X-ray emission from copper tracer layers is often employed. A...
A mature dairy cow was transitioned from a high forage (100% forage) to a high-grain (79% grain) diet over seven days. Continuous ruminal pH recordings were utilized to diagnose the severity of ruminal acidosis. Additionally, blood and rumen papillae biopsies were collected to describe the...
The effects of exercise intensity on post-exercise measures of intestinal permeability and absorption in sedentary and in active young men were examined in this study. Measures were compared bewteen rest, low intensity and high intensity interval exercise interventions. In spite of the exercise...
Ruminal acidosis is a persisting digestive disorder in modern ruminant production; however, the susceptibility of cows to ruminal acidosis differs among cows fed a common diet. The overall objective of this research was to evaluate factors affecting the susceptibility of cows to ruminal acidosis....
