Study Description:

Blood samples were collected from six different Bos taurus herds between day 27 and 285 of gestation (heifers n = 1,205 and cows n = 1,539). Blood samples to determine PAG clearance interval were collected weekly postpartum for up to 12 weeks (heifers n = 418 and cows n = 657). Serum was tested using the lateral flow test and were read by two technicians who were blind to pregnancy status. Level of agreement between the tests were determined by Pearson’s correlation coefficients and Kappa scores. The MIXED procedure of SAS was used to evaluate the effect of …

The Measurement Of College Athletes' Knowledge And Behavior On Pre-And Post-Workout Nutrition Utilizing A Text-Message Intervention, Hannah Christine Young

Theses and Dissertations

The purpose of this study was to measure athlete’s knowledge on pre- and post-workout nutrition, specifically assessing their macronutrient intake. Nutrition education for collegiate athletes has been a popular topic of discussion for years. Illinois State University athletes participated in the study by completing a pre- and post- sports nutrition survey which consisted of 29 questions. This survey regarding nutrition knowledge specifically included questions based off their pre-workout intake, recovery, as well as behavior-related questions based off a 1-7 Likert Scale (one being disagree and seven being agree).

A total of 40 participants completed both the pre- and post-assessment surveys. …

Conceptual Framework To Integrate Economic Drivers Of Decision Making For Technology Adoption In Agriculture, Thiago L. Romanelli, Francisco Muñoz-Arriola, Andre F. Colaço

Department of Agricultural and Biological Systems Engineering: Faculty Publications

This study evaluates how much technology adoption could cost in a variety of crop-production scenarios. Cost-reduction simulations consider scenarios of higher input use efficiency such as reducing the usage of diesel, labor, irrigation, fertilizer, herbicide, and seed, among others. The scenarios aim to increase yields by integrating the effect of each input-reduction on the total operating costs. Agricultural production estimates for Nebraska in the US indicates that a technology that saves 1% of diesel is cost-effective, costing between USD 0.15/ha and USD 0.32/ha (for corn). Improvements on input use efficiency should be prioritized to incentivize technology development and adoption. This …

Effects Of Maturity And Drying Method On The Nutritive Value Of Tropical Grasses In Nicaragua, Rocky Lemus, R. Van Der Hoek, Y. C. Newman, M. Mena, K. A. Albrecht

IGC Proceedings (1977-2023)

Tropical grasses are key components for both grazing and conserved forages in sustainable livestock systems (beef and dairy) in Central America. The objective of the study was to evaluate grasses used in Nicaragua and their nutritive value contribution as preserved forage during the dry season under different drying methods. Five tropical bunch grasses (Andropogon gayanus, Hyparrheniarufa, Urochloabrizantha, Megathyrsus maximus, and Cenchruspurpureus) were sampled across different farms in Nicaragua in 2014 and 2015 using three replications. Forage samples were collected at 2, 4, 6, and 8-wk maturity as well as season long samples. Samples drying …

Effects Of Harvest Frequency On Yield And Self-Thinning In Irrigated Orchardgrass (Dactylis Glomerata L.) In Oregon, Usa, G. Jones

IGC Proceedings (1977-2023)

Persistence is an important factor in the economic management of perennial grass swards. Frequent harvest is occasionally attributed to poor stand persistence, but self-thinning theory indicates that infrequent harvest should cause swards to thin as tillers compete for light. This experiment aimed to demonstrate and qualify self-thinning in orchardgrass managed under differing harvest frequencies. Orchardgrass was planted in September 2018 and then clipped, fertilized and divided into experimental units in March 2019. Plots were randomly assigned one of four harvest frequency treatments (n = 5): No harvest, one harvest, two harvests, and four harvests. Irrigation water and fertilizer were …

State And Transition Models In Space And Time – Using Stms To Understand Broad Patterns Of Ecosystem Change In Iceland, I. C. Barrio, D. S. Hik, T. A. Mulloy, J. Thorsson, K. Svavarsdóttir, B. Marteinsdóttir, I. S. Jónsdóttir

IGC Proceedings (1977-2023)

Managing ecological systems sustainably requires a deep understanding of ecosystem structure and the processes driving their dynamics. Conceptual models can lead to improved management, by providing a framework for organizing knowledge about a system and identifying the causal agents of change. We developed state-and-transition models (STMs) to describe landscape changes in Iceland over three historical periods with different human influence, from pre-settlement to present days. Our models identified the set of possible states, transitions and thresholds in these ecosystems and their changes over time. To illustrate the use of these models for predicting and improving management interventions, we applied our …

Soil Water Movement In A Watershed In The Chilean Patagonia, J. Ivelic-Sáez, P. Cisternas, J. Dörner, J. Arumí, J. Valenzuela, E. Muñoz, S. Valle, H. Alonso, R. López, H. Uribe

IGC Proceedings (1977-2023)

Magallanes region, located southern Chile, contains about 1.9 million sheep heads, in about 5 million hectares of rangelands. However, forage production is concentrated in small wetlands meadows called locally “Vegas” that only represent about 300.000 hectares. Those ecosystems that sustain patagonian ranches, produce 20 times more forage biomass than the surrounding natural rangelands. Patagonian vegas have concave topography with a hydrophyte (wet) center, and mesic slopes and xeric highlands of Festuca gracillima. Although the moisture content is controled by topography, there is scarce information about the movement of water through this concave topography. Also, the spatial variability of the …

Simple Guidelines For Deciding When Soil Variability Does – And Doesn’T – Matter For Rangeland Management And Restoration, Jeff E. Herrick, J. Maynard, B. Bestelmeyer, A. Ganguli, J. Glover, K. Johnson, D. Kimiti, J. Neff, G. Peacock, J. Peters, S. Salley, P. Shaver, K. Shepherd, Z. Stewart, R. Van Den Bosch

IGC Proceedings (1977-2023)

“Rangelands in most parts of the world are relatively homogenous and can be managed uniformly at the landscape scale” or “rangelands are extremely diverse and require different approaches even at the landscape scale.” Both statements are made frequently by rangelands scientists and managers. Both are correct. Whether or not it is worthwhile to consider soil variability when planning management and restoration at the landscape scale depends on objectives, location, and the management or restoration strategies under consideration. Together these factors determine whether outcomes are likely to be different at different locations in the landscape, and whether those outcomes can be …

Effects Of Banana Peels On Chicken Weight Gain And Egg Production In The Urban And Peri-Urban Areas Of Aksum City, Ethiopia, H. G. Araya, S. G. Gebrekristos, W. V. Oliver

IGC Proceedings (1977-2023)

High feed cost of running urban-animal-agriculture and huge city wastes are challenges of the growing towns in modern Ethiopia. Egg production microenterprise is steadily growing due to its low initial investment and ready market in urban and peri-urban areas. However, cost of egg production is high due to the rising cost of corn, the main feed ingredient in poultry rations. Using banana peels, which forms a great proportion of city waste in Ethiopia, is seen as a way of not only reducing the waste, but also as an alternative low-cost feed supplement that could help enhance egg production by small-holder …

Sheep Grazing Patterns For Better Land Management: Adjusting Gps Tracking Protocol, J. Castro, L. M. Godoy, J. P. Castro, M. Castro

IGC Proceedings (1977-2023)

Small ruminant livestock systems in northeast Portugal are an extensive activity based on daily grazing paths across the landscape. The flocks use multiple patches of multiple land cover types in different ways throughout the year. Shepherd and flock interactions determine the resting and feeding spots utilized by sheep and goats according to the biotic and abiotic conditions. Information about the herding home range is central to managing the land use and vegetation cover and optimizing sheep and goats' productivity in traditional systems. This study's main objective is to contribute to calibrate a shepherding GPS protocol to monitor sheep flocks based …

IGC Proceedings (1977-2023)

Drylands cover 40% of the global land area and host 2 billion people, of which 90% live in low- or middleincome countries. Drylands often face severe land degradation, low agricultural productivity, rapid population growth, widespread poverty, and poor health. Governance structures and institutions are often eroded. Livestock-based livelihoods, largely depending on seasonal migration are common. Pastoralist communities and their land are highly vulnerable to climate shocks, while there are also changes in land tenure, insecurity/conflicts and rapid infrastructure development. Drylands Transform is an interdisciplinary research project revolving around the UN Sustainable Development Goals (SDGs). The project aim is to contribute …

Role Of Different Shrubs In Soil Seed Bank Conservation In Different Climates Of Iran, Reza Erfanzadeh, Fatemeh Barzegaran, Shadi Hazhir, Sirus Saber Amoli

IGC Proceedings (1977-2023)

Shrubs often produce positive effects on understory soil seed bank (SSB) characteristics. However, the effect of shrubs on SSB could be variable in different habitats depending on the climate and the type of shrub. In this study, the effect of Crataegus pseudomelanicarpa (humid areas, northern Iran), Onobrychis cornuta, Berberis integerrima and Juniperus sabina (sub alpine areas, northern Iran) and, Astragalus myriacanthus and Acantholimon spinosum (semi-arid areas, central Iran) on SSB characteristics was studied. Soil samples were collected under the canopy of shrubs and the control (out of canopies) from 0-5 cm and 5-10 cm depths by auger and seed germination …

Range Condition Classification Based On Quantitative Characteristics Of Vegetation, Nafiseh Fakhar, Mansour Mesdaghi, Kamal Naseri

IGC Proceedings (1977-2023)

Change in range condition classes over time are usually the basis for monitoring management effectiveness. Several approaches have been proposed to monitor the range condition classes in relation to a bench mark usually called climax stage. There are some types of range condition classification often included in a range inventory. In this paper, six factors of canopy cover, litter frequency, plant vigour, soil protection percentage, plant composition, and present production as a percentage of indicative state were described for determination range conditions. We have determined range condition classes by using R software. This method was developed by FAO projects in …

Should Missouri Consider The Social Cost Of Carbon In Policymaking?, Matthew Geer

SLU Law Journal Online

The social cost of carbon (SCC) is a tool used by federal agencies to quantify the cost of carbon emissions in policymaking. As concerns surrounding climate change become more pressing, some states have also begun using the SCC in their own policies, rules, and regulations, while other states like Missouri have actively challenged the metric. In this article, Matthew Geer looks at the origin of the federal social cost of carbon and considers its effectiveness as a tool by state governments to guide policymaking that will prevent climate change from causing irreversible harm to Planet Earth.

Elgin's "Native Tongue": A "Me Too" Universe?, Amir Barati

Tête à Tête: Journal of Francophone Studies

Suzette Haden Elgin’s novel Native Tongue (1984) provides a fascinating critique of the ideologies inscribed into patriarchal language and evokes an extremely valuable linguistic and political awareness. This article will examine the liability of the ways the novel revolts against the patriarchal society via the introduction of a gynocentric linguistic intervention. I claim, Elgin’s novel showcases an invaluable instance of how it is possible for women to revolt against the pillars of patriarchy through manipulations at the gestalt and schematic level of language and most specifically, the bodily metaphoric quality of the English. This proposed transformation of the schematic and …

Transgressing Boundaries Of Identity, Geography And Time In Transmutadxos And La Mucama De Omicunlé, Lucinda Smith

Tête à Tête: Journal of Francophone Studies

The literary works of Rita Indiana (1977) and Yolanda Arroyo Pizarro (1970) are recognised for exposing and challenging hegemonic ideas of identity, sexuality and power. The transgression of boundaries appears time and again in the fiction of both writers, whether these be boundaries of sexual or gender identity, desire, geography, time or even life and death. Using Rita Indiana’s novel La mucama de Omicunlé (2015) and Arroyo’s collection of short stories Transmutadxs (2016), the authors’ representations of such transgressions are the focus of this essay.

Further to addressing similar themes in their texts, both Rita Indiana and Arroyo Pizarro were …

“Bovarique” Bodies From 19th Century France To 20st Century London, Andisheh Ghaderi, Anoosheh Ghaderi

Tête à Tête: Journal of Francophone Studies

Women’s bodies have always been charged by social associations that aim to control, shape, and discipline women. The frustrations and the ennui caused by sociocultural and political constraints push women to a state of existential crisis and eventually a erasure through biological death. Such vicious cycles had been depicted in the literary works to which Gustave Flaubert’s Madame Bovary (1856) serves as a prominent example. Flaubert’s protagonist, Emma Bovary represents the pathway of a young, provincial, woman to a tragic adulthood filled with banality, emptiness, and despair. Objects, ranging from journals to clothes, are omnipresent in Emma’s life and shape …

Writing Desire On The Lesbian Body: Baudelaire’S Fantasies And Vivien’S Realities, Emily Wieder

Tête à Tête: Journal of Francophone Studies

In The Flowers of Evil [Les Fleurs du Mal (1857)], French poet Charles Baudelaire paints three female bodies: the mistress, the prostitute, and the lesbian. The latter appears in three of one-hundred poems but so captivated Baudelaire that he almost titled the collection The Lesbians. Censors nevertheless condemned the anthology and suppressed two of the lesbian poems. The remaining lesbian poem compares the “damned women” to “thoughtful cattle.” A rare representation of lesbian bodies, this metaphor problematically depicts them as savage.

Yet this “Other” exemplifies the baudelairean poetic ideal. By crafting Beauty, the Poet immortalizes his corpus. As the …

Developmental Functioning Of Infants And Toddlers With Neurodevelopmental Disorders, Megan Callahan

LSU Master's Theses

Autism spectrum disorder (ASD), epilepsy, and cerebral palsy (CP) are some of the most common neurodevelopmental disorders among children with prevalence rates of 1.85% (Maenner et al., 2020), 1.2% (Zack & Kobau, 2017), and between 0.21 and 0.31% (Christensen et al., 2013), respectively. These neurodevelopmental disorders are highly comorbid with each other and with other disorders, such as intellectual disability (ID). While previous research has investigated developmental functioning in these neurodevelopmental disorders, it has primarily focused on only two at a time and in older children or adults. The current study aimed to investigate developmental functioning in these neurodevelopmental disorders …

Not So Different As Cats And Dogs: Companionship During The Covid-19 Pandemic, Shelly Volsche, Elizabeth Johnson

People and Animals: The International Journal of Research and Practice

COVID- 19 lockdown provided a unique, in situ opportunity to probe caretaker experiences of living with companion animals during a stressful event. We launched an online survey in the United States that included standard demographic questions, questions related to household structures, and 25 Likert scale questions that probed perceptions of whether and how respondents’ relationships changed during social isolation. This paper uses a subset of that data specific to dog and cat guardians. A principal components analysis and Mann-Whitney U test returned no significant differences between cat and dog guardians on three scales (Scale 1: Psychological Well-being, Scale 2: …

The Role Of Terrestrial Productivity And Hydrology In Regulating Aquatic Dissolved Organic Carbon Concentrations In Boreal Catchments, Xudan Zhu, Liang Chen, Jukka Pumpanen, Anne Okjala, John Zobitz, Xuan Zhou, Hjalmar Lauren, Marjo Palviainen, Kimmo Neitola, Frank Berninger

Faculty Authored Articles

The past decades have witnessed an increase in dissolved organic carbon (DOC) concentrations in the catchments of the Northern Hemisphere. Increasing terrestrial productivity and changing hydrology may be reasons for the increases in DOC concentration. The aim of this study is to investigate the impacts of increased terrestrial productivity and changed hydrology following climate change on DOC concentrations. We tested and quantified the effects of gross primary production (GPP), ecosystem respiration (RE) and discharge on DOC concentrations in boreal catchments over 3 years. As catchment characteristics can regulate the extent of rising DOC concentrations caused by the regional or global …

Relationship Of Dag1 And Serpina5 Sperm Proteins With Bull Fertility, Saulo Menegatti Zoca, Julie Walker, Jerica J. J. Rich, Kaitlin M. Epperson, Taylor N. Andrews, Adalaide C. Kline, Jessica Nora Drum, M. Sofia Ortega, George Perry

SDSU Beef Day 2022 Summary Publication

Study Description:

Semen from 22 dairy bulls was used to evaluate the presence, localization, and quantification of DAG1 and SERPINA5 on sperm. Sperm motility parameters and viability was also evaluated for semen from each bull. Semen from 19 out of the 22 dairy bulls was used for in vitro embryo production (two Low-SCR and one High-SCR were not available for in vitro embryo production). Bulls were classified based on their sire conception rates (SCR) values as High-SCR (SCR > 1.0) or Low-SCR fertility (SCR < -4.0). Low fertility bulls were subdivided based on their blastocyst rate (BL) as High-BL (Low-SCR/High-BL BL ≥ 31%) or Low-BL (Low-SCR/Low-BL BL ≤ 26%), and High-SCR bulls were not subdivided. The GLM procedure in SAS was used with bull as a fixed effect to determine if variance was greater between bulls compared to within bull. Correlations were determined among DAG1 and SERPINA5 concentrations, percentage of tail labeled for SERPINA5, SCR, sperm total motility, progressive motility, and viability, and in vitro embryo produced cleavage rate (CL) and BL. The GLIMMIX procedure of SAS was used to evaluate the relationship of bull field fertility (High- and Low-SCR), and field and in vitro fertility (High-SCR, Low-SCR/High-BL, Low-SCR/Low-BL) classifications with sperm total (TMOT) and progressive (PROG) motility, viability, CL, BL, DAG1 and SERPINA5 relative concentration, and proportion of sperm tail labeled for SERPINA5. Both SERPINA5 and DAG1 were localized on the sperm head; however, SERPINA5 was also localized on the sperm tail. There was greater variance in concentration among bulls compared to within bull for both DAG1 (P < 0.01; 69.4 vs 49.1, respectively) and SERPINA5 (P < 0.01; 325.8 vs 285.4, respectively). There was a positive correlation between concentration of DAG1 and SERPINA5 (P = 0.01; r = 0.54). Concentrations of SERPINA5 were also correlated with CL (P = 0.04; r = 0.48), and percentage of sperm tail labeled for SERPINA5 was correlated with viability (P = 0.05; r = 0.44) and tended to be correlated with CL (P = 0.10; r = 0.39). There was no relationship between SCR or BL rate classifications and DAG1 (P ≥ 0.66), SERPINA5 (P ≥ 0.54), or percentage of sperm tail labeled for SERPINA5 (P ≥ 0.48).
