Methods To Reduce Nitrogen And Carbon Losses From Finishing Beef Cattle, Hanna K. Cronk

Department of Animal Science: Dissertations, Theses, and Student Research

A finishing experiment evaluated the effect of incremental supplemental rumen-protected lysine on beef cattle performance. All cattle were fed the same diet of high moisture corn, dried rolled corn, modified distillers grains plus solubles, corn silage, and supplement with inclusion levels of lysine ranging from 0 to 7 grams/day, in 1 g increments. Dry matter intake (P ≤ 0.04) and ADG (P ≤ 0.04) decreased linearly as supplemental lysine increased in the diet with no effect on final carcass adjusted feed efficiency (P ≥ 0.34). In the initial 64 days of the experiment, increasing lysine in the …

Plant-derived vesicles (PDVs) are attractive for therapeutic applications, including as potential nanocarriers. However, a concern with oral delivery of PDVs is whether they would remain intact in the gastrointestinal tract. We found that 82% of cabbage PDVs were destroyed under conditions mimicking the upper digestive tract. To overcome this limitation, we developed a delivery method whereby lyophilized Eudragit S100-coated cabbage PDVs were packaged into a capsule (Cap-cPDVs). Lyophilization and suspension of PDVs did not have an appreciable impact on PDV structure, number, or therapeutic effect. Additionally, packaging the lyophilized Eudragit S100-coated PDVs into capsules allowed them to pass through the …

Adverse Birth Outcomes: Investigating The Role Of Nativity And Perceived Racial Discrimination Among Black Mothers Enrolled In Des Moines, Iowa Healthy Start., Kendria Kelly-Taylor

Electronic Theses and Dissertations

Birth outcomes for Black women in the United States (US) are disproportionately worse in comparison to non-Black women, even when controlling for potential confounders. Existing studies suggest foreign-born (FB) Black women present better birth outcomes in comparison to US-born (USB) Black women. Also, the longer FB Black women live in the US, the more their perinatal health advantage diminishes. Racial discrimination has been hypothesized as a potential reason for this decline. This dissertation investigates the relationship between nativity and adverse birth outcomes while also exploring how the reporting of racial discrimination impacts birth outcomes among FB and USB Black mothers …

Social Capital And Academic Achievement In Arkansas, Misty D. Newcomb

Graduate Theses and Dissertations

The purpose of this study is to demonstrate a more comprehensive understanding of the impact that a child’s broader context has upon his or her academic outcomes, and presumably, life. Using Bronfenbrenner’s theory of human development, this study examines the extent to which social capital and student achievement are correlated and whether an infusion of funding for schools that presumably lack social and economic capital might predict academic achievement in schools from economically depressed regions. Findings indicate that some aspects of social capital and funding initiatives have a demonstrated impact on student achievement but there is not a correlation with …

Influence Of Pregnant Cattle Grazing Endophyte-Infected Tall Fescue On Offspring Immune Function, Sidney Nicole Dunkel

Graduate Theses and Dissertations

The objective was to evaluate the influence of pregnant cattle grazing endophyte-infected tall, toxic, fescue (E+) during gestation on innate immune response of male offspring to an endotoxin challenge. Crossbred multiparous cows (n = 36) were bred to Red Angus sires and housed in replicated E+ or novel endophyte-infected, non-toxic, fescue (NE+) pastures prior to breeding and throughout gestation. From this calf-crop, a subset of post-weaned steers (n = 8 E+; n = 8 NE+) were selected for a lipopolysaccharide (LPS) challenge. Blood was collected every 30 min beginning 2 h prior to (Pre-LPS) and continuing 9 h following (Post-LPS) …

Study Of Weight Gain In Freshman Students At The University Of Arkansas, Lily Maleknia

Graduate Theses and Dissertations

This study was designed to examine the poor (non-nutritional) food choices that college freshman make when living on-campus and eating at on-campus dining facilities. These poor choices lead to excessive weight gain, eating disorders, declining health and wellness, and mental health issues (i.e. depression, anxiety, lack of self-confidence). These side effects can lead to a less than desirable 1st year college experience and lack of academic success. Based on these concerns, different investigations have been performed to determine the causes of this phenomena. Given adolescent weight gain is highly linked to being overweight and obesity in adults, a better understanding …

Patients with germline SDHD pathogenic variants (encoding succinate dehydrogenase subunit D; ie, paraganglioma 1 syndrome) are predominantly affected by head and neck paragangliomas, which, in almost 20% of patients, might coexist with paragangliomas arising from other locations (eg, adrenal medulla, para-aortic, cardiac or thoracic, and pelvic). Given the higher risk of tumour multifocality and bilaterality for phaeochromocytomas and paragangliomas (PPGLs) because of SDHD pathogenic variants than for their sporadic and other genotypic counterparts, the management of patients with SDHD PPGLs is clinically complex in terms of imaging, treatment, and management options. Furthermore, locally aggressive disease can be discovered at a …

Disruption Of Play Behavior Influences Development Of Caution In Juvenile Ground Squirrels, William Ryan

Master's Theses

Play behavior is ubiquitous among young mammals and has a variety of important influences on early development. I evaluated possible influences of social play behavior on the development of temperament in juvenile Belding’s ground squirrels (Urocitellus beldingi), using the caution/boldness spectrum as a measure of temperament. I disrupted the play behavior of juvenile U. beldingi by walking toward juveniles at play until the play interactions stopped. I used undisrupted juveniles and juveniles whose non-play behavior was disrupted at regular intervals as controls. Caution was measured with behavioral tests during which a human intruder walked toward a squirrel and recorded the …

The Tragedy Of The Common? A Comparative Population Genomic Study Of Two Bumblebee Species, Jana V. Huml, Jonathan S. Ellis, Sarah Rustage, Mark J.F. Brown, Richard Billington, Mairi E. Knight

School of Biological and Marine Sciences

Within the theoretical framework of the small population paradigm, we investigated the population genomics and parasite load of two bumblebee species across the UK and Ireland. Bombus pratorum is widespread and common throughout its range while Bombus monticola is restricted to higher altitudes and shows a more fragmented distribution. Bombus monticola showed stronger population structuring, isolation-by-distance, and a deficit of heterozygotes in the most isolated population in the south of its range (Dartmoor). Heterozygosity and inbreeding coefficients (FIS) were comparable between both species, but the proportion of polymorphic sites was much greater in B. pratorum. Notably, both species have suffered …

Using Metal-Organic Frameworks (Mofs) In Producing Self-Curing Concrete, Lama Fathi Allan

Theses

Curing of concrete is the presence of adequate moisture content in concrete throughout its early stages to produce the desired properties, as it is significant in improving the concrete microstructure and pore structure and hence in developing its performance and durability. However, good curing is not always practical in several cases, such as in hot weather regions and areas of water inadequacy. For that reason, the need to develop self-curing concrete attracted several researchers. The use of self-curing agents minimizes the water evaporation from concrete and consequently increases its water retention capacity compared to conventional concrete. This thesis is concerned …

Assessing Stream Ecosystem Structure And Function In An Urban Canal And Logan River In Logan, Utah, Ellie Smith-Eskridge

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Humans have constructed canals to support agriculture, to mitigate flooding, and to discharge stormwater, especially in the Intermountain West. These canals are common in Cache Valley, where they receive flows from the Logan River during summer months. However, the ecological structure (e.g., water quality, freshwater invertebrates) and function (e.g., leaf decomposition) of these canals remains largely unknown. Studying ecosystem structure and function of these urban waterways is important because it can inform us of the health of these waterways.

My research had three objectives. First, I compared water chemistry, invertebrate assemblages, and leaf decomposition in an urban canal and the …
