Divergent Selection For Water Conversion Ratio In Broiler Populations, Joseph Hiltz

Graduate Theses and Dissertations

Water scarcity is a global reality and with the anticipated population growth, freshwater resources will be further strained to meet both human needs and agriculture applications. To ensure a water sustainable and food secure future, all aspects of agriculture must become more efficient. Two strategies were explored. The potential of improving water efficiency in broilers was examined. The first strategy was to develop a more efficient and accurate method for measuring water consumption/inputs in agriculture. To date, water measuring technology has lacked the necessary sophistication to assure accuracy and repeatability of low flow water usage.

After establishing a low flow …

Obesity Prevention Toolkit To Combat Weight Gain Related To Sedentary Behavior And Dietary Habits In College Students: An Evidence-Based Project, Maria Amos, Martha Fuller

Doctor of Nursing Practice Final Manuscripts

Abstract

Background: Forty percent of the US population ages 20-39 are categorized as obese,

their BMI is over 30, and 35% of college age students are obese or overweight. Issues related to obesity cost the US $147 billion annually. Between 40%-50% of college students are reported to be inactive. Inactivity can lead to increased morbidity and mortality related to increased risks of cardiovascular disease, diabetes, hypertension, musculoskeletal issues, and depression. Providing dietary and physical activity education and access to nutritional information promotes behavior change in young adults.

Aims of Service Change: This evidence-based project proposal aims to provide a toolkit …

How Background Factors Affect Culinary Skills And Knowledge, Mackenzie Harrell

Human Nutrition and Hospitality Management Undergraduate Honors Theses

Students preparing to be registered dietitians must learn and retain culinary skills and knowledge so they can use it in their future career. If dietitians’ nutritional knowledge is limited to medical situations, they cannot educate the public about planning and preparing healthy meals. The purpose of this study was to determine if a student’s history of cooking, shopping for groceries, and other background factors affect culinary skills and knowledge, and to determine the appropriate curriculum for undergraduate students to prepare them for their career as a dietitian. This study was in part a continuation of an assessment conducted by my …

Exploring How Maternal Phosphorus Status Affects Calf Growth And Performance, Elizabeth Lafferty

Animal Science Undergraduate Honors Theses

This study will focus on how maternal phosphorus status of beef heifers affects the growth and performance of their calves. Heifers have been offered free-choice mineral with either 0 or 4% supplemental phosphorus from 30 days after weaning until calving. A study by H. Hilfiker, a University of Arkansas honors student, investigated the effects of these treatments from 30 days after weaning until 60 days after the breeding season when heifers were confirmed to be bred or open. For this developing heifer project 64 crossbred Angus heifers were assigned randomly into 8 groups (8 heifers/ group) before assigning each group …

Impact Of Different Plant-Based Foods Consumption On The Composition And Diversity Of Gut Microbiota, Ayoub Al Othaim

Graduate Theses and Dissertations

Plant-based diets are primarily derived from plant sources, including fruits and vegetables. Such patterns are associated with health benefits by promoting general health and preventing many diseases and metabolic disorders. Fruits and vegetables are key sources of high-quality nutrients such as dietary fibers and polyphenols. Since they are rich in dietary fibers and polyphenols, whole fruits and vegetables represent unique and somewhat understudied modulators of the gut microbiota and its associated functions. This study aims to (i) investigate the impact of varying dilutions of cherry juices concentrate on the composition of the murine gut microbiota, (ii) investigate the impact of …

Preceptorship Within Accredited Nutrition And Dietetics Programs: A Pragmatic Mixed Methods Study, Angela K. Brekken

Dissertations, Theses, and Projects

The purpose of this pragmatic mixed-methods study was to identify the factors that impact a nutrition professional’s preceptorship decision and potential solutions to combat preceptor shortages within accredited nutrition and dietetics programs. Homan’s social exchange theory provided the theoretical framework that if perceived costs of preceptorship outweigh the perceived benefits, then the activity will cease.

Phase one of the study included an online mixed-methods questionnaire. Phase two included a qualitative focus group and interview with self-identified volunteers from phase one. Quantitative analysis through SPSS included descriptive statistics (means and standard deviations) and inferential statistics (one-way ANOVA). Qualitative data for both …

Evaluating The Nutritional Adequacy Of Peruvian-American Children, Delainey Dietz

Honors Undergraduate Theses

As people move and integrate cultures, nutritional trends may change from those of their native country to those of their new country. With today's increasing global immigration, studies have only scratched the surface of the impact of acculturation on children's health and nutrition. Specifically, the Peruvian-American diet is one that has garnered minimal research. The purpose of this study is to evaluate the common foods and drinks that Peruvian-American children consume, assess the children's physical health, and discuss the possible causative factors of any diet trends. The population sampled is children under 18 years living in the United States whose …

The Effect Of Nutrition On Longevity And Fertility In Diverse Drosophila: A Tor-Mediated Process, Tessa E. Steenwinkel

Dissertations, Master's Theses and Master's Reports

Nutrition and growth are strongly linked, but not much is known about how nutrition leads to growth. To understand the connection between nutrition through diet, growth and/or proliferation, we need to study the phenotypes resulting from the activation and inhibition of central metabolic pathways. Here I use the model organism Drosophila melanogaster (D. mel.) and three non-model Drosophila species with different dietary needs, Drosophila guttifera (D. gut.), Drosophila deflecta (D. def.), and Drosophila tripunctata (D. tri.), to study the effects of dietary amino acid availability in these diverse flies on fecundity and …
