Evaluation Of Plant Growth Regulators On Sweetpotato Slip Propagation, Kerington Lyn Bass
Theses and Dissertations
Sweetpotato production is often impacted by high mortality of slips during transplantation to the field, particularly with greenhouse-grown slips. These slips develop thinner stems, thus being more vulnerable to transplant shock, resulting in reduced establishment. To address this issue, the study evaluated the effects of four plant growth regulators on the morphological and anatomical characteristics of sweetpotato slips. In the first experiment, external growth parameters were recorded over four weeks, followed by post-harvest assessments of plant and root material. In the second experiment, the widths of various stem structures in stained cross-sections of slip stems were measured. Results showed that …

The Effects Of Ataxin-1 Overexpression In The Central Nervous System On Specific Behavioral And Physiological Characteristics Of Drosophila Melanogaster, Sydney Davis
Theses and Dissertations
Spinocerebellar ataxia type 1 (SCA1) is a dominantly inherited neurodegenerative disease caused by a CAG repeat expansion in the ataxin-1 gene, which results in an abnormally long polyglutamine tract. Similarly, overexpression of wildtype Ataxin-1 (wt-Atx-1) in Drosophila melanogaster leads to neurodegeneration, reduced lifespan, and impaired negative geotaxis. Observations include disruptions in sleep-wake cycles, increased oxidative stress biomarkers (like protein carbonyls), and dysregulation of developmental genes such as armadillo (arm) and nemo kinase (nmo). Additionally, elevated expression of SUMOylation-related genes (Aos-1, Uba2, and dSmt3 or dSumo) and increased SUMO protein levels indicate enhanced SUMOylation in the brain. Quantitative analysis of neuronal …

Assessment Of Pagp Gene Function In Avian Pathogenic Escherichia Coli Pathogenicity Using Different Challenge Models, Hailey Fugate
Theses and Dissertations
Avian pathogenic Escherichia coli (APEC) is a leading cause of morbidity and mortality in poultry, contributing an estimated $40 million in annual losses in the U.S. broiler industry alone, and contributing to growing concerns over antibiotic resistance. This study investigated the role of the pagP gene, which encodes a lipid A palmitoyl transferase involved in immune evasion, using both a broiler chick and embryo challenge model. Deletion of pagP significantly reduced mortality and lesion severity in broilers, indicating its role in APEC pathogenicity. However, in embryos, pagP deletion had minimal effects on survival and bacterial colonization, suggesting alternative virulence mechanisms …

Evaluating The Use Of Translucency Score As An Effective Parameter Of Eggshell Quality, Cassidy Autumn Morris
Evaluating The Use Of Translucency Score As An Effective Parameter Of Eggshell Quality, Cassidy Autumn Morris
Theses and Dissertations
The objective of this thesis was to determine if an egg’s translucency score (TS) could be used as an effective predicting parameter to determine eggshell quality in both broiler breeders and commercial laying hens. In broiler breeders, it was determined that TS could be used as an effective predicting parameter for eggshell thickness (P< 0.001) and L* scores (P< 0.001). It was also found that the supplementation of organically sourced trace minerals could significantly decrease the TS of eggs, resulting in a better-quality eggshell (P< 0.001). In two different aged commercial laying hen experiments, there was no conclusive evidence for TS to be a predictive parameter of eggshell quality throughout the storage period. It was found, however, that the storage period did significantly increase the TS throughout storage in both experiments (P< 0.001).

Poultry producers must continuously evaluate current practices and determine new ones to further optimize broiler production. Sodium bisulfate (SB) is used as a poultry litter amendment (SBL), but also in human food to control pH; thus, initiating interest for SB in feed (SBF) for performance and gut health benefits. This thesis utilized common diets varying in SBF (Chapters II and III) and SBL (Chapter II; SBL1- d 0 and SBL2 – d 0 and 18) to optimize 40 d broiler performance, litter quality, and d 41 processing metrics. For Chapter II, d 0 SBL1 dramatically lowered litter pH, while minimally …
Effects Of Environmental Stress And Antimicrobials On The Health, Microbiome, And Product Shelf-Life Of Channel And Hybrid Catfish, Guyue Tang
Theses and Dissertations
Two studies investigated various aspects of channel and hybrid catfish production and processing. The first study examined the effects of ammonia stress (15 mg/L vs. 1 mg/L control) on growth performance and fillet quality. While channel catfish demonstrated superior growth, ammonia stress minimally impacted the sensory profiles of both species. Gut microbiota analysis revealed species-specific differences, with Lactococcus lactis dominating hybrid catfish communities. The second study evaluated buffered vinegar treatment (1.5%) on fillet shelf life during refrigerated storage. Vinegar-treated fillets maintained better microbiological quality, with aerobic plate counts remaining below 7 log cfu/g through day 6, while untreated fillets exceeded …

Wildfires can produce health impacts that persist for years in affected communities. This article describes an Extension-led study of health impacts in rural Oregon communities one year after a destructive wildfire. Data collection included key informant interviews (n=36), an online survey (n=80), and three focus group interviews with survivors (n=23). Mental health, exposure to contaminants, physical stress, food insecurity, and other issues were frequently identified health concerns. Survivors’ difficulties in dealing with housing displacement significantly exacerbated health challenges. We describe potential roles for Extension in addressing wildfire risk and mitigating health impacts, including a description of the Oregon Fire Program.
