Examining The Hormonal Underpinnings Of Affiliation Motivation In Oral Contraceptive Users, Hormonal Iud Users, And Naturally Cycling Women, Mikayla Tolliver
Graduate Theses and Dissertations
Affiliation is important for women during times of stress. Although, affiliation has been linked to women’s hormones across the menstrual cycle, many women use hormonal contraceptives which disrupt the links between hormones, psychology, and behavior. This study examined how hormonal contraceptives (hormonal IUD vs. the oral contraceptive pill) and menstrual cycle phase (follicular vs. luteal) are associated with affiliative motivations following the Trier Social Stress Test (TSST). Further, this study examined women’s cortisol reactivity and whether cortisol reactivity mediated affiliative motivation following the stressor. I found that oral contraceptive pill users projected more stress and rejection onto others’ faces and …

The Effects Of Probiotics And Environment On The Swine Gut Microbiome, Bin Zuo
Graduate Theses and Dissertations
The gastrointestinal tract is crucial for nutrient absorption and immune system functionality. It employs a synergistic approach, merging physical and biochemical defenses, to counteract pathogens that enter through dietary or other external routes. This system also facilitates the breakdown of complex carbohydrates, a process beyond the host's innate capacity. In swine, gut microbiota early colonization plays a significant role in several physiological developments, shaped by a variety of determinants including maternal factors and environmental conditions. In the swine industry, the shift to indoor pig farming enhances efficiency but limits soil interaction, potentially impacting gut microbiota diversity. Additionally, the practice of …

The Intersection Of Employee Engagement And Employee Health: A Quantitative Evaluation Of The Use Of Engagement Tactics In Improving The Health Of A Workforce, Andrew Buffenbarger
The Intersection Of Employee Engagement And Employee Health: A Quantitative Evaluation Of The Use Of Engagement Tactics In Improving The Health Of A Workforce, Andrew Buffenbarger
Graduate Theses and Dissertations
Employers have a vested interest in the health of employees, but employee wellness programs have not proven themselves an effective tactic for employers to motivate employees to live healthier lives. Employees who suffer from chronic disease are less productive than healthier peers, are more expensive to insure, have higher rates of absenteeism, and are more prone to suffer from performance-reducing levels of stress and burnout (Shuck et al., 2021; Jones et al., 2019; Mattke et al., 2013). The problem is that employee wellness programs are often not effective at improving the health of employee populations (Song & Baicker, 2019; Jones …
Assessment Of Dietary Energy And Amino Acid Diet Formulation In The Modern Broilers, Matheus Freitas Costa
Assessment Of Dietary Energy And Amino Acid Diet Formulation In The Modern Broilers, Matheus Freitas Costa
Graduate Theses and Dissertations
As a result of the advancement of genetics, understanding broiler requirements for dietary energy and amino acids is essential for improving live performance and carcass characteristics. The energy system used to formulate diets in poultry is based on metabolizable energy (ME); this equation can be described as the total amount of energy in the feed minus gases and feces. However, the net energy (NE) system may be the best depiction of the energy utilized by birds for production and maintenance purposes once the heat increment (HI) is measured. Thus, a series of studies were conducted to establish the responsiveness of …
The Effects Of Diet, Size, And Phylogeny On Primate Dental Proportions, Rudolph J. Wilkins
The Effects Of Diet, Size, And Phylogeny On Primate Dental Proportions, Rudolph J. Wilkins
Graduate Theses and Dissertations
It is generally appreciated that there is a relationship between the relative size of the incisors, mandible length, and diet in primates. More specifically, the differences in relative incisor size among primate species are believed to be evolutionary adaptations to their use during food processing and acquisition. While this satisfactorily explains relatively large incisors, it fails to address the relatively small incisor size seen in many taxa. One hypothesis is that there is a trade-off between molar size and incisor size in species with relatively short mandibles. The following study uses two-way ANOVA to evaluate the possibility that spatial constraint …
Determination Of P Availability In Feedstuffs And The Effect Of Feedstuffs And Anti-Nutritional Factors On Secretory Iga Production And Host Nutrient Losses In Poultry, Benjamin Parsons
Graduate Theses and Dissertations
The availability of P in feedstuffs and the effect of feedstuffs, feed additives, and anti-nutritional factors on secretory IgA (sIgA) production in chickens were evaluated. A rapid method was developed using the precision-fed rooster assay to evaluate phytic acid disappearance, P digestibility, and phytase efficacy. Further, exogenous phytase was found to be effective at degrading myo-inositol 1,2,3,4,5,6-hexakis, however, the enzyme was less efficient at P release from lower inositol phosphates. The availability of P in feedstuffs was found to be affected by dietary Ca content, where increasing Ca linearly reduced (P < 0.05) both phytic acid hydrolysis and P digestibility. For example, the standardized ileal digestibility of P was reduced from 73 to 47% in soybean meal when the dietary Ca content was increased from 0.30 to 0.75%. The digestibility of P in distillers dried grains with solubles (DDGS) and corn fermented protein (CFP), however, was high across all Ca levels (71 to 80%). Relative P bioavailability based on tibia bone ash was also found to be high for DDGS and CFP, being 81 and 78%, respectively. Upon further evaluation, it was observed that utilizing low dietary Ca levels (0.30%) when P digestibility in individual plant-based feedstuffs was determined overestimated the P digestibility in practical grower diets by up to 16 percentage units. Utilization of higher Ca levels (0.75%) when P digestibility in individual plant-based feedstuffs was determined, however, resulted in calcualted P digestibility values that were within 1 to 3 percentage units of the measured digestibility in practical grower diets. Aside from P, feedstuffs were also evaluated to determine their effect on sIgA production in the intestine. Roosters excreted approximately 6 to 30 mg of sIgA / 24 h. Further, the proportional contribution of sIgA to total endogenous amino acid (AA) losses ranged from 1 to 13%, with the greatest contribution being observed for Trp. The addition of casein to a protein-free diet increased (P < 0.05) sIgA production in both roosters and broiler chickens. There was no change (P > 0.05) in sIgA production compared with the protein-free diet …

Nutrient Responses To Hippuric Acid In Sheep Urine Applied To Pasture Soil Cores, Ethan Avery Collins
Nutrient Responses To Hippuric Acid In Sheep Urine Applied To Pasture Soil Cores, Ethan Avery Collins
Graduate Theses and Dissertations
Hippuric acid is a breakdown product of tannins, which bind with proteins in the animal rumen and slow down protein metabolism, thus increasing nitrogen (N) retention in the animal. Increased hippuric acid concentration in bovine and ovine urine applied to soil may decrease rates of nitrification, denitrification, and nitrous oxide fluxes in pasture soils. Additionally, condensed tannins have increased rates of carbon mineralization when incorporated in humus and leaf litter. To evaluate effects of hippuric acid concentration, treatments of urine from sheep fed a tannin-supplemented diet, synthetic urine, or urea controls were applied to intact soil cores seeded with crabgrass …

Rice Material State Diagrams: Trends Of Contemporary Cultivars And Influence Of Nitrogen Application During Production, Evans Ameyaw Owusu
Graduate Theses and Dissertations
Rice is typically harvested at high moisture content (MC) levels which necessitates drying to low MC levels for safe storage. However, drying at inappropriate temperatures and durations can lead to deterioration of kernel quality such as fissure formation. Kernels with these fissures are typically associated with reduced head rice yields and significant economic losses. Material state diagrams for rice have been created by the University of Arkansas Rice Processing Program (UARPP) as a tool to aid in predicting the ideal temperatures to use during drying and tempering (a process of holding rice at the drying temperature for some duration). The …
Dietary Histidine: Broiler Responsiveness With And Without Endogenous Histidine Reserve Consideration, Kenneth Blake Nelson
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 …

Anti-Inflammatory Effect Of Apiaceous Vegetables In A Mouse Model Of Colitis - Implications For Colon Cancer Risk, Laura Mariana Mariana Echavarri Ibarra
Graduate Theses and Dissertations
Colorectal cancer is the second leading cause of cancer-related deaths in the US. Dietary habits account for 50% of the cases. A westernized diet (high fat, high sugar/fructose, and low in fruits and vegetables) and inflammatory bowel diseases are risk factors for colorectal cancer. Evidence suggests phytochemicals in apiaceous vegetables (API; celery family) possess anti-inflammatory and potentially chemopreventive properties. Hence, investigation of whether the consumption of API mitigates acute colitis is warranted. Using mice fed the Total Western Diet (TWD) and administered dextran sodium sulfate (DSS; induces colitis), the objectives of this project are to identify the effects of API …
