Pet Diet Changes While Taking An Animal Nutrition Course, Joanna Ramirez

Undergraduate Research Conference

This study investigates the impact of an animal nutrition course on pet owners during the Fall of 2023. The primary objective is to determine how a pet owner's perception of their pet's diet changes and to identify any corresponding alterations made to the pet's diet before and while taking an animal nutrition course. Two surveys were conducted to collect responses: the pre-survey received 18 responses from animal nutrition students regarding their pets' diets before taking the course, and the post-survey received 18 responses from animal nutrition students regarding any changes in their pets' diets while taking the course.

• Supplementation of melatonin or cytokine (FLI) could aid in oocyte quality and mitochondrial membrane distribution/potential.
• The aim of this study was to evaluate 1) if supplementation of melatonin/cytokine (FLI) during in vitro maturation has an impact on maturation rates in oocytes and 2) if supplementation/temperature affect mitochondrial membrane distribution/potential in bovine oocytes.

Developmental Characteristics And Renovating Pattern Of Reed Canarygrass Shoots In A Sward, M Ito, S Mizuno, T Otani, S Kobayashi

IGC Proceedings (1977-2023)

Developmental and renovating traits of shoots were investigated ecomorphologically in a reed canarygrass (Phalaris arundinacea L., cv. Palaton) sward harvested 3 times per year. Reed canarygrass shoots exhibited notably high growth rates both in the 1st and 2nd crops together with rapid leaf formation (around 7 days/leaf) and active internode elongation. Vigorously growing shoots, which regenerated soon after the 1st cutting and dominated in the 2nd crop canopy, mainly originated from the stubble formed with 3 to 4 phytomers that developed after the beginning of spring growth, thus resulting in higher shoot density than that of the 1st crop. …

Canopy Changes In Healthlands (Erica-Ulex) Grazed By Sheep Or Goats, R Celaya, K Osoro

IGC Proceedings (1977-2023)

The grazing effects of sheep and goats on vegetation dominated by heaths (Erica spp) and gorse (Ulex gallii) were studied for two years. Two plots were grazed from May to October 1992 by 7 ewes or 7 does and in the following year each plot was subdivided into two subplots subsequently grazed either by sheep or by goats in a factorial design. During the first grazing season both sheep and goats reduced similarly the cover percentage of shrubs since the herbaceous content was scarce, although goats reduced more the height of the shrubs than sheep. The cover …

Effect Of Nitrogen, Phosphorus, Potassium And Cutting On The Regrowth And Insect Infestation Of A Sorghum And Berseem Clover In Egypt, M B. Attia

IGC Proceedings (1977-2023)

The objective of this study was to determine the minimum quantities of phosphorus and potassium which must be applied with varying amounts of nitrogen in order to maintain maximum hay production and minimum level of insect infestation. This was more pronounced at the higher N rates and caused a significant N x K interaction during each of these years. There was no yield response to applied phosphorus at any N rate. Relation between levels of nitrogen and infestation percentage was positive but infestation rate decreased with the increase of potassium levels while there was no relation between levels of phosphorus …

Cynodon Dactylon Control In Conservation Tillage Systems, A Rios, J M. Sanz

IGC Proceedings (1977-2023)

Bermudagrass (Cynodon dactylon L. PERS.) is the most important weed in Uruguay. With the development of conservation tillage systems, chemical control of bermudagrass becomes essential. The objective of this research was to evaluate, in a long term integrated program, bermudagrass chemical control during the first year of a pasture. Application of glyphosate and no-tillage seeding of the pasture took place during fall. A 70% reduction of underground part of the weed was detected. The chemical control, together with a conservation tillage system and an adequate pasture management allowed an important reduction in bermudagrass level for the first year pasture. …

Legume Seedling Development In No Till Pasture Establishment, J L. Rossi, V A. Deregibus

IGC Proceedings (1977-2023)

The objective of this study was to compare no-till and conventional seeding of pasture and their effects on legume establishment. The presence of residue cover reduced legume seedling establishment and weed population under no-till seeding. The reduction in establishment was associated with the physical impediment of the residue cover and the decay of seedling vigor when passing through that cover.

Ecotypic Adaptation Of Medicago Polymorpha Along A Gradient In Central Chile: Growth And Seed Production, A Del Pozo, C Ovalle, J Avendano

IGC Proceedings (1977-2023)

Relative growth rate, total dry weight and seed yield on 19 accessions of burr medic (Medicago polymorpha L.) from different bioclimatic conditions, were assessed at Cauquenes (35°58’;72°17’W) in the subhumid mediterranean region. The accessions were sown in microplots over raised beds during two years (1991 and 1992), and swards cut periodically at 2, 6 and 10 cm height. There were significant differences between accessions in both total dry weight and seed yield (P < 0.001, Table 1), but the interaction between accessions and height of cutting was not significant (P > 0.05). Total dry weight was positive correlated with days to flowering (r2 = 0.81; P > 0.01).

Morphogenesis And Growth Analysis Of Panicum Maximum Cultivars, A Gomide, C A.M Gomide

IGC Proceedings (1977-2023)

Four cultivars of Panicum maximum, grown in pots, were evaluated regarding their leaf appearance and elongation rates, tillering appearance rate, as well as growth indices. Differences among cultivars were found as to leaf appearance and elongation rates and tillering rates. Main tiller leaf appearance was higher relative to primary tiller in the seedling growth, only. Primary tiller showed higher leaf elongation rate in the aftermath growth. No difference among cultivars was found for drymatter yield after 52 d growth period, leaf mortality, net assimilation rate, leaf area ratio and relative growth rate.

Competitive Interactions Between Palatable And Unpalatable Grasses: Effects Of Selective Defoliations Of The Palatable Grasses, R A. Distel, A S. Moretto

IGC Proceedings (1977-2023)

Selective herbivory of the palatable species appears to be a dominant mechanisms contributing to species competitive replacement in grasslands. Selective herbivory of the palatable species allows unpalatable species to realize a competitive advantage within the community. To test this hypothesis we compare the competitive ability of the unpalatable grasses Stipa trichotoma or S. gyneriodes in the presence of nondefoliated and defoliated plants of the palatable grass S. clarazii. The three species are native to a temperate semiarid grassland of Argentina. The response variables estimated in S.trichotoma and S.gynerioides, at both plant and tiller levels, were higher (P < 0.05) in the presence of defoliated than in the presence of undefoliated plants of S.clarazii. These results support the hypothesis that selective herbivory of the palatable species confers unpalatable species a competitive advantages, contributing to species competitive replacement within the community.

Early Ontogenetic Responses Of Six Commercial Chloris Gayana Cultivars To Salinity, E Taleisnik, H Perez, G Peyrano, C Arias

IGC Proceedings (1977-2023)

Some physiological aspects relevant to pasture establishment under saline conditions were evaluated in six cultivars of Chloris gayana . Two tetraploid cultivars: Boma and Callide, and four diploid ones: Bell, Katambora, Pioneer and a local accession of Pioneer, were analyzed. The effect of salinity on seedling emergence, the number of stolons per plant and frost tolerance were evaluated in the field, while effects on germination, early vegetative growth, regrowth after clipping, ion accumulation and stolon rooting were assessed in the greenhouse. Salinity had a negative effect on seedling emergence. Saline solutions delayed or altogether inhibited germination, but seeds retained viability …

Anything But Another Essay: Understanding Undergraduate Stem Student Perceptions Of Creative, Project-Based Learning, Emily M. Redding, Lorelei E. Patrick

SACAD: Scholarly Activities

The training of innovative and diverse scientists starts with creative teaching practices. Much of the pedagogy literature on incorporating nontraditional teaching practices in college STEM courses focuses on the use of in-class active learning activities. Less study has been devoted to creative, project-based assignments, such as “UnEssays”. The “UnEssay” is a semester-long assignment that challenges students to complete a library research project on a topic of their choosing and present it using anything but an essay. Although gaining popularity, few studies have assessed STEM student's perceptions of the assignments. To do so, Zoology students were asked to complete pre- and …

A Novel Study Of Cliff Swallow (Petrochelidon Pyrrhonota) Feather Coloration In Relation To Habitat Characteristics, Colony Size, And Body Condition, Sonja Brandt, Medhavi Ambardar

SACAD: Scholarly Activities

Feather coloration is used for social signaling in many avian species, and can be associated with their ability to live and breed in habitats with high quality resources (Jenkins et al. 2013, Saino et al. 2013). It can signify individual quality, (Saino et al. 2013) and influence mate choice (Bennet et al. 1996). We analyzed different aspects of Cliff Swallow (Petrochelidon pyrrhonota) feather coloration in relation to morphology and habitat characteristics. We measured luminance, hue (theta and phi), and saturation for four different color patches on the swallows. We predicted that individuals in brighter coloration would be able to settle …

Theses and Dissertations

For Utah Lake in Utah, USA, we analyzed a uniquely comprehensive and longitudinal water quality dataset that extended over two summer sampling seasons. We measured 61 parameters using Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), YSI ProDSS water sondes, and laboratory procedures to quantify and characterize dissolved and suspended behavior of trace elements in Utah Lake. We analyzed the data using principal component analysis (PCA) and multidimensional scaling (MDS) to understand the lake geochemistry and inform Utah Lake management decisions regarding nutrients and algal blooms. We found that 1) sediments rich in phosphorus (P) act as a source for bioavailable …

The Conceptual Foundations Of Innate Immunity: Taking Stock 30 Years Later, Thomas Pradeu, Bart P.H.J. Thomma, Stephen E. Girardin, Bruno Lemaitre

Presidential Fellows Articles and Research

While largely neglected over decades during which adaptive immunity captured most of the attention, innate immune mechanisms have now become central to our understanding of immunology. Innate immunity provides the first barrier to infection in vertebrates, and it is the sole mechanism of host defense in invertebrates and plants. Innate immunity also plays a critical role in maintaining homeostasis, shaping the microbiota, and in disease contexts such as cancer, neurodegeneration, metabolic syndromes, and aging. The emergence of the field of innate immunity has led to an expanded view of the immune system, which is no longer restricted to vertebrates and …

Apigenin Alleviates Autistic-Like Stereotyped Repetitive Behaviors And Mitigates Brain Oxidative Stress In Mice, Petrilla Jayaprakash, Dmytro Isaev, Keun-Hang Susan Yang, Rami Beiram, Murat Oz, Bassem Sadek

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Studying the involvement of nicotinic acetylcholine receptors (nAChRs), specifically α7-nAChRs, in neuropsychiatric brain disorders such as autism spectrum disorder (ASD) has gained a growing interest. The flavonoid apigenin (APG) has been confirmed in its pharmacological action as a positive allosteric modulator of α7-nAChRs. However, there is no research describing the pharmacological potential of APG in ASD. The aim of this study was to evaluate the effects of the subchronic systemic treatment of APG (10–30 mg/kg) on ASD-like repetitive and compulsive-like behaviors and oxidative stress status in the hippocampus and cerebellum in BTBR mice, utilizing the reference drug aripiprazole (ARP, 1 …

The Effect Of Sodium Bicarbonate Supplementation In Markers Of Gut Permeability And Gastrointestinal Discomfort After Exercise In The Heat, Suzana Andrade De Oliveira

Health, Exercise, and Sports Sciences ETDs

Exercise performed under heat stress conditions is associated with an increase in gut permeability, commonly known as "leaky gut.". Recent studies suggest that sodium bicarbonate ingestion (NaHCO3) before exercise in the heat may offer ergogenic benefits. However, NaHCO3 is known to induce gastrointestinal discomfort (GI) and potentially exacerbate gut permeability. Therefore, this study investigated the effects of NaHCO3 on markers of gut permeability and gastrointestinal discomfort after prolonged physical exercise in a hot environment. To test this, we analyzed markers of intestinal permeability and injury pre and post exercise under heat stress comparing a NaHCO3 group to a placebo group. …

The Oracle Of The Pig's Head, Taylor L. Denton

LSU Master's Theses

The Oracle of the Pig’s Head is a collection of two poems, a short story, and a novel centered around themes of the role of the feminine body in society, monstrosity, disgust, divinity, and human impact on the environment. Inspired by other works of eco-criticism, gothic literature, surrealism, Appalachian folklore, and Greco-Roman mythology, this collection explores how marginalized bodies interact in a world forever altered by climate change.

Denton is primarily interested in how severe climate change has influenced not only human’s overall relationship to the environment, but also how writers are meant to engage with a world riddled with …
