Positive-RADG beef steers (n = 8; RADG = 0.76 kg/d) and negative-RADG beef steers (n = 8; RADG = -0.64 kg/d) were …

Improving Nutrition Screening Practice In The Hospitalized Heart Failure Patient Population, Amanda J. Bourgeois

DNP Projects

Background: Heart Failure is a disease known to affect nearly 6.5 million adults in the United States. Characterized by recurrent hospitalizations, heart failure significantly contributes to morbidity, mortality, and healthcare costs in the United States and worldwide. Because malnutrition is prevalent in the heart failure population, healthcare providers must perform nutritional assessments on admission to intervene in the case of malnutrition, prevent deterioration, and improve patient prognosis. Without intervention and early identification of malnutrition, heart failure hospitalizations will remain a significant problem.

Purpose: The purpose of this study is to evaluate the effect of an evidence-based educational program for cardiac …

Longevity,Feeding Behavior, And Egg Production Of Adult House Flies (Musca Domestica) Provided With Potential Farm Foods, Anna Elise Grimenstein

House flies (Musca domestica) are cosmopolitan pests to both humans and livestock, and they can vector many diseases. House flies are especially associated with livestock facilities, as adult flies lay eggs in rotting organic matter such as manure. While it is understood that the diet an adult fly receives can affect biological parameters such as longevity and egg production, not much research has been done to address foods that are accessible to house flies in their natural habitat. The present study examined the longevity, feeding behavior, and egg production rates of adult house flies given different foods they would have …

The Energetics Of Seasonality In Wild Diademed Sifaka (Propithecus Diadema): A Technical And Biological Validation Of Fecal Triiodothyronine Radioimmunassay, Casey Farmer

Graduate Research Theses & Dissertations

The energetic state of an animal has vital consequences for its fitness, but it can be difficult to detect through behavioral observations. The development of techniques to determine an animals’ energetic state non-invasively would allow conservation planners to rapidly assess the energy balance and conservation potential of individuals, groups, and populations. Thyroid hormones like triiodothyronine (T3) regulate and reflect metabolic state in mammals. T3 is a non-invasive biomarker that can be detected in feces and could potentially be used for this purpose. I perform the first validation of a commercially available T3 radioimmunoassay designed for humans on a wild strepsirrhine …

Revisiting The Master Food Volunteer Program: Examining How To Enhance Nutrition Education In The United States, Stacey Viera, Lindsey Haynes-Maslow

Journal of Extension

America’s diet-related illness crisis intersects with a lack of nutrition literacy, nutrition security, and systemic inequities. The Cooperative Extension Service’s (CES) national infrastructure could potentially provide equitable access to quality nutrition education in the US utilizing a Master Food Volunteer (MFV) model. This research brief examined preliminary evidence for the MFV model as a support for CES agents and paraprofessionals, and results show a paucity of evidence. Further research and a pilot program with pre-established measures for health-related knowledge and behaviors could elucidate the model’s potential to increase equitable access to evidence-based programming, nutrition, and implementation guidance.

Evaluation Of Heat Stress And Dietary Amino Acid Density On Nutrient And Energy Partitioning In Broilers, Jean-Remi Teyssier

Graduate Theses and Dissertations

The simultaneous increase in the global demand for animal-based protein products and the rise in temperature associated with global warming pose important challenges to the poultry industry. Heat stress (HS) occurs when an animal’s heat production (HP) surpasses its capacity to dissipate heat into the surrounding environment, ultimately leading to reduced feed intake (FI) and negative impacts on performance. A better understanding of bird responses to elevated temperatures is required to propose effective nutritional strategies that mitigate the adverse effects of HS. Therefore, this dissertation aimed to characterize the nutritional and physiological mechanisms explaining the loss in performance and carcass …

Dietary Histidine: Broiler Responsiveness With And Without Endogenous Histidine Reserve Consideration, Kenneth Blake Nelson

Graduate Theses and Dissertations

In the past, histidine warranted little concern from poultry nutritionists because it was seldom deficient in practical broiler diets. With most essential amino acids now commercially available as feed-grade forms to partially replace intact protein ingredients, histidine and its minimum in least-cost formulation are receiving fresh attention. Published histidine requirement data for broilers are sparce, and many of these studies have been conducted on males within the first three weeks post-hatch. Moreover, rudimentary dose-response experimental designs may not be applicable to estimate histidine requirements in later growth periods because histidine is uniquely stored within the body. In times of dietary …

The Influence Of Nutrition On The Gut Microbiota And Psychiatric Disorders: A Review, Megha Bhagavan, Francis Jenney

Research Day

The symbiotic harboring of gut microorganisms within the gastrointestinal tract has a profound influence on host physiology, well-being, and disease pathology. More specifically, the gut bacteria are able to interact with dietary components from foods chosen by the host and consequently relay their beneficial or precarious effects locally and systemically. The gut bacteria have the capacity to maintain a healthy gut microbiome or perpetuate intestinal imbalance, known as gut dysbiosis. Gut dysbiosis has both local effects in gastrointestinal pathologies, such as intestinal bowel syndrome (IBS) and intestinal bowel disorder (IBD), as well as systemic pathologies, such as type II diabetes, …

Lessons From Chloroviruses: The Complex And Diverse Roles Of Viruses In Food Webs, John Delong, James L. Van Etten, David Dunigan

School of Biological Sciences: Faculty Publications

Viruses can have large effects on the ecological communities in which they occur. Much of this impact comes from the mortality of host cells, which simultaneously alters microbial community composition and causes the release of matter that can be used by other organisms. However, recent studies indicate that viruses may be even more deeply integrated into the functioning of ecological communities than their effect on nutrient cycling suggests. In particular, chloroviruses, which infect chlorella-like green algae that typically occur as endosymbionts, participate in three types of interactions with other species. Chlororviruses (i) can lure ciliates from a distance, using them …
