Influence of subclinical hypocalcemia on plasma biochemical parameters, liver histologic changes, and common postpartum diseases in dairy cows
(University of Missouri--Columbia, 2011)
We hypothesized that cows with subclinical hypocalcemia at calving would have greater elevations in liver associated biochemical parameters and non-esterified fatty acid (NEFA) concentrations compared to normocalcemic cows. ...
Implications of ovarian and uterine maturity evaluated in replacement heifer candidates
(University of Missouri--Columbia, 2021)
of heifers via reproductive tract evaluation. Disparities in ovarian and uterine maturity may be detected at the time of evaluation in peripubertal heifers. Two experiments were conducted to characterize the incidence and implications of disparate ovarian...
Active learning engagement classrooms at the University of Central Missouri : practical strategies to implement and sustain utilization of active learning in higher education using technology
(University of Missouri--Columbia, 2020)
traditional lecturing to active learning using technology. Focus group meetings and interviews were conducted with 44 faculty, staff, and student participants at the University of Central Missouri. While mostly positive, faculty and students had mixed reviews...
Factors affecting neonatal beef calf metabolism and vigor
(University of Missouri--Columbia, 2021)
Two studies were conducted to investigate factors affecting neonatal beef calf metabolism and vigor. In the first study, effects of late gestational nutrient restriction on colostrum yield, neonatal vigor, and blood chemistry ...
Utilizing hydrologic soil grouping to estimate corn nitrogen rate recommendations
(University of Missouri--Columbia, 2019)
Nitrogen fertilizer recommendations in corn (Zea mays L.) that match crop N need are imperative to increasing profitability and preventing environmental contamination. However, processes influencing corn production (i.e. ...
Resource extraction, resistance, and religion in Nicaragua
(University of Missouri--Columbia, 2019)
mining, especially related to economic threats and grievances tied to environmental and agricultural concerns, it will likely continue its resistance movement until it sees policy changes that halt or overturn mining concessions in the community. However...
“Now there's a good woman”: how rural life course events shape the response to cognitive decline in older women
(University of Missouri--Kansas City, 2012-05-22)
Aims: This dissertation aimed to: (1) analyze the life-course experiences of rural, older women and the impact of those experiences on their values, health-illness behaviors and decision-making, particularly surrounding cognitive decline; (2...
Genetic basis of isoflavone accumulation during soybean seed development : special focus on water-deficit conditions
(University of Missouri--Columbia, 2009)
Soybean (Glycine max [L] Merr.) seed isoflavones have long been considered a desirable trait to target in selection programs for their contribution to human health and plant defense systems. The plant synthesizes isoflavones ...
Reflections of residents in a rural Midwestern community on the impacts of a successful university football program, their tendency to bask in reflected glory, and their social identity
(University of Missouri--Columbia, 2022)
), the perceptions and lived experiences of residents in a rural Midwestern community and the impacts of a successful university football program that inhabits their community. While the study sought to contribute to the existing literature connected to BIRG and SIT...
An ecological study of American Ginseng (Panax quinquefolius L.) in the Missouri Ozark Highlands: effects of herbivory and harvest, ecological characterization and wild simulated cultivation
(University of Missouri--Columbia, 2006)
Matrix population analysis was used to analyze eight years of demographic data from six American ginseng (Panax quinquefolius L.) populations in east-central Missouri to examine effects of herbivory by white-tailed deer (Odocoileus virginianus Zimm...
Interspecific interactions between olive trees and grapevines in vineyard agroforestry systems in an arid climate region
(University of Missouri--Columbia, 2021)
for nutrients may affect vines within 4 m of trees, although other studies suggest that trees may actually improve vineyard soil quality. Existing literature also shows that vine yield is reduced within 4 m of trees. Our experiment on a Malbec/olive tree alley...
Landscape and inchannel factors affecting the distribution and abundance of riverine smallmouth bass in Missouri
(University of Missouri--Columbia, 2008)
I developed a series of spatially-nested research objectives to identify habitat elements related to the distribution and abundance of riverine smallmouth bass Micropterus dolomieu in Missouri. The range of smallmouth bass was identified using a few...
Resveratrol and procyanidin content in select Missouri red wines
(University of Missouri--Columbia, 2009)
in the skins of grapes and are present in higher quantities in red wines than white wines. These polyphenols levels have been reported for wines around the world. However, the Norton grape is one of the predominant grapes grown in Missouri, and there is limited...
Evaluating and improving corn nitrogen fertilizer recommendation tools across the U.S. Midwest
(University of Missouri--Columbia, 2018)
Determining which corn (Zea mays L.) nitrogen (N) recommendation tools best predict the economically optimal N rate (EONR) would be valuable for maximizing profits and minimizing environmental consequences. The objectives ...
Genetic architecture and marker-assisted breeding for salt tolerance in soybean
(University of Missouri--Columbia, 2018)
Salinity is one of the major abiotic stresses that inhibits plant growth and causes seed yield loss in soybean. Although a major gene for salt tolerance on chromosome (Chr.) 3 was mapped, cloned and characterized, it does ...
Rheological and morphological evolution of basaltic lava flows
(University of Missouri--Columbia, 2018)
Over 500 million people live in proximity of an active volcano globally. Although lava flows rarely endanger human life, they often destroy critical infrastructure. Advancing our understanding of lava flow dynamics is ...
