Sentiment Analysis, Quantification, And Shift Detection, Kevin Labille Dec 2019

Sentiment Analysis, Quantification, And Shift Detection, Kevin Labille

Theses and Dissertations

This dissertation focuses on event detection within streams of Tweets based on sentiment quantification. Sentiment quantification extends sentiment analysis, the analysis of the sentiment of individual documents, to analyze the sentiment of an aggregated collection of documents. Although the former has been widely researched, the latter has drawn less attention but offers greater potential to enhance current business intelligence systems. Indeed, knowing the proportion of positive and negative Tweets is much more valuable than knowing which individual Tweets are positive or negative. We also extend our sentiment quantification research to analyze the evolution of sentiment over time to automatically detect ...


Components Of Mindfulness Training: Impacts On Attention And Affect, Maximilian Fey Dec 2019

Components Of Mindfulness Training: Impacts On Attention And Affect, Maximilian Fey

Theses and Dissertations

The literature on mindfulness supports a distinction between two components of non-judgmental acceptance and directed attention. The present research analyzed whether there are distinct differences in attentional capabilities or affect between mindfulness inductions which differed in either including only directed attention or directed attention and non-judgmental acceptance. I hypothesized that the acceptance component of mindfulness would increase participants sustained attentional capabilities relative to a control condition; furthermore, I hypothesized that the non-judgmental acceptance component of mindfulness would lead to significant increases in positive affect and decreases in negative affect relative to control. Lastly, I hypothesized that an individual difference measure ...


Collecting Aztalan: An Analysis Of The Chipped Stone Projectile Points From The Milwaukee Public Museum’S Aztalan (Je-0001) Legacy Collections, Kevin Akemann Dec 2019

Collecting Aztalan: An Analysis Of The Chipped Stone Projectile Points From The Milwaukee Public Museum’S Aztalan (Je-0001) Legacy Collections, Kevin Akemann

Theses and Dissertations

This thesis is a qualitative analysis of chipped stone projectile points from the Milwaukee Public Museum that were obtained from private collectors who reportedly surface collected these artifacts from the site of Aztalan (47-JE-0001). Private collections like these, referred to as Legacy Collections, are the result of early collecting and excavation practices, by private and professional individuals, and in this research, have been only partially examined in relation to Aztalan and mostly overlooked in favor of materials with more reliable and scientific provenience. Through this research I developed a database from the MPM's digital inventory, handwritten catalogs, accession records ...


Information Structure In Standard Arabic Verbal Sentences, Salem Albuhayri Dec 2019

Information Structure In Standard Arabic Verbal Sentences, Salem Albuhayri

Theses and Dissertations

This thesis investigates Information Structure (IS) in relation to the clausal architecture in Standard Arabic (SA). The attention is confined to word order variation and its role in structuring discourse. The structural positions with potential information structure import are argued to appear at the edg-es of phases, namely vP and CP. It presents an analysis which brings together the minimalist scheme as embodied in Chomsky (2000, onwards) and the cartographic approach to discourse as embodied in Rizzi (1997, 2001) and Cinque (1999). First, in chapter (‎2) a distinction is made be-tween VSO and SVO clauses, in which I propose that ...


An Intersectional Analysis Of The Role Race And Gender Play In Welfare Recipients’ And Case Manager Experiences, Stephanie Baran Dec 2019

An Intersectional Analysis Of The Role Race And Gender Play In Welfare Recipients’ And Case Manager Experiences, Stephanie Baran

Theses and Dissertations

This dissertation is an ethnographic study of food insecurity in Milwaukee and how people receiving benefit assistance understand themselves, others and how they thought others understand them. This frame was duplicated for social workers and poverty organizations in the Milwaukee area. Using a series of theoretical viewpoints, the study utilizes racial theories, as well as, symbolic violence and annihilation to discuss how various aspects of recipients, social workers and poverty organizations interact within the theoretical margins. Taking place over one and a half years and including 350 observation hours at a local food pantry, the study found that respondents feel ...


Looking For Group: Sociality, Embodiment, And Institutions In World Of Warcraft, Christopher J. Cooley Dec 2019

Looking For Group: Sociality, Embodiment, And Institutions In World Of Warcraft, Christopher J. Cooley

Theses and Dissertations

This ethnography examines the varying degrees of conflict between multiple stakeholders involved in the massively multiplayer online role-playing game World of Warcraft (WoW). The game’s designers, like many software developers in the contemporary world, tend to be guided by an ideology influenced by classical liberalism, but also inspired by a utopian view of technology in general. That ideological position has directly affected many aspects of the game, from the largely unregulated in-game economy, to the strong emphasis on individual mastery of the game’s systems to progress through the complete content of the game world. World of Warcraft advertises ...


Sexual Dimorphism And The Shape Of The Proximal Tibia In A Radiographic Sample, Emily Eiseman Dec 2019

Sexual Dimorphism And The Shape Of The Proximal Tibia In A Radiographic Sample, Emily Eiseman

Theses and Dissertations

SEXUAL DIMORPHISM AND THE SHAPE OF THE PROXIMAL TIBIA IN A RADIOGRAPHIC SAMPLE

This study investigates the use of radiographs to determine sexual dimorphism in the shape of the tibia. The goal of the research was to identify a small set of markers that would allow researchers to efficiently and accurately determine a person’s sex from a radiograph of the proximal tibia.

The sample consisted of radiographs including 75 females and 46 males ranging in age from 21 to 81. Measurements were taken on 27 points around the area of the knee including the tibia, patella, and femur. The ...


Heirloom And Hybrid Corn In The American Corn Belt: An Ethnography Of Seed Saving Practices, Rachelle Halaska Dec 2019

Heirloom And Hybrid Corn In The American Corn Belt: An Ethnography Of Seed Saving Practices, Rachelle Halaska

Theses and Dissertations

This ethnographic study examines the practices and context of contemporary heirloom corn seed saving practices and projects in the American Corn Belt. It examines heirloom corn conservation and hand pollination practices at Seed Savers Exchange in Decorah, Iowa in 2015. From there the study extends to interviews with heirloom farmers, breeders and gardeners in Wisconsin and Illinois. The findings indicate that the lines between the mainstream and the margins of corn production are highly blurred, and that there is a considerable amount of cross-pollination of ideas and practices between alternative corn farming and dominant industrial hybrid production in the American ...

Consumer Health Information Needs, Seeking And Searching Behavior By Rural Residents In The Kachia Grazing Reserve, With A Focus On Vector-Borne Diseases, Musa Dauda Hassan

Theses and Dissertations

Information is considered the basic material for making decisions. People from all walks of life have information needs for business and personal use. Consumer Health Information (CHI) is an emerging form of information made accessible to the layperson. It is a simplified form of information from the types of information available to medical professionals. This study examines the health information behavior of the residents of one region in the Kachia Grazing Reserve (KGR) located in the North West of the six geopolitical zones of Nigeria. This dissertation explores the health information needs, seeking and searching behavior of the residents of ...


Investigation Of The Relationship Between Mindfulness And Empathy In Pre-Nursing Students Exposed To A Four-Week Mindfulness Training, Debra L. Klich Dec 2019

Investigation Of The Relationship Between Mindfulness And Empathy In Pre-Nursing Students Exposed To A Four-Week Mindfulness Training, Debra L. Klich

Theses and Dissertations

Objective: To investigate the effects of a four-week mindfulness program on levels of mindfulness, empathy, and anxiety in a group of pre-nursing students.

Methods: This study utilized a multiple-baseline across subjects design. Results from nine study participants were examined.

Results: Data demonstrates that a detectable decrease in anxiety levels can result from participation in self-directed mindfulness program as short as four weeks. Results regarding mindfulness and empathy levels were less conclusive. A specific relationship between empathy and mindfulness cannot be determined from this study.

Conclusions: Because previous studies have demonstrated a persistence of skills, practice, and benefits acquired through mindfulness ...


Economic Policy Uncertainty And Macroeconomic Activity: An Asymmetric Approach, Majid Makinayeri Dec 2019

Economic Policy Uncertainty And Macroeconomic Activity: An Asymmetric Approach, Majid Makinayeri

Theses and Dissertations

In the new global economy, uncertainty has become a critical determinant of financial and economic stability. This thesis aims to study the impact of uncertainty on a set of macroeconomic variables such as demand for money, investment, and consumption. Different measures of uncertainty are used by scholars in the investigation of money demand, investment, and consumption like monetary and output uncertainty. This study employs a more general and inclusive measure of uncertainty, policy uncertainty, which measures uncertainty in fiscal, regulatory and monetary policies. By implementing a Nonlinear Autoregressive Distributed Lag (ARDL) model, I aim to identify possible non-linear effects of ...

Pena, Pinahua, And Prestige: Shame And Linguistic Insecurity In Upper Balsas Classrooms, Heather Gabrielle Thomas Flores

Theses and Dissertations

This ethnography is a topical analysis of the Indigenous Education system in rural Guerrero, Mexico. The purpose of this research is to draw out the correlations between coercive monolingual ‘Spanish only’ language policies implemented during the mid 20th century and the systematic disintegration of the Nahuatl language within what were once monolingual Nahua communities in the Upper Balsas valley. The data presented in this paper is framed and analyzed through language ideologies discourse. The conceptualizations of language held within the cultural ideology allow for the complexities surrounding language loss and revitalization to be taken into consideration within their dynamic and ...

BUSINESS-SCHOOL PARTNERSHIPS IN CAREER AND

TECHNICAL EDUCATION

by

Michael E. Trimberger Jr.

The University of Wisconsin-Milwaukee, 2019

Under the Supervision of Professor Dr. Elise Frattura

Public education in Wisconsin has come under harsh political scrutiny in recent years. Schools have been asked to reduce budgets and use the tools provided through legislative changes. The reduction of budgets has not come with a reduction of expectations for our schools. Since 2011, high school principals have been forced to implement Academic Career Plans and ensure that every student graduate college and career ready along with their already comprehensive list of requirements ...


Are Two Unmatched Minority Statuses Worse Than One? The Impact Of Social Status Similarities On Alliance In A Mock Clinical Interview, Roselee Jeannette Ledesma Dec 2019

Are Two Unmatched Minority Statuses Worse Than One? The Impact Of Social Status Similarities On Alliance In A Mock Clinical Interview, Roselee Jeannette Ledesma

Theses and Dissertations

Strengthening therapeutic alliance through social identity matching has been a strategy used to reduce psychotherapy dropout among racial/ethnic and sexual minority clients. Limited research has examined social identity match by manipulating social identity (e.g., race/ethnicity, sexual orientation) in an analogue therapy setting. This study (1) assessed whether self-reported alliance was positively associated with theoretical proxies of alliance and (2) examined the effects of racial/ethnic and sexual orientation match on therapeutic alliance (self-reported) and proxies of alliance (perceived similarity, liking, blame, empathy, closeness, microaggression proxies, verbal validation, and open body language). Participants (N = 71) were heterosexual White ...


Food For Thought: An Analysis Of The Robenhausen Botanicals At The Milwaukee Public Museum, Ann S. Eberwein Dec 2019

Food For Thought: An Analysis Of The Robenhausen Botanicals At The Milwaukee Public Museum, Ann S. Eberwein

Theses and Dissertations

Museum collections excavated from archaeological sites represent an intersection of disciplines and provoke innovative approaches to the study of these material aspects of culture. Botanical collections of food remains in particular, provide an opportunity to interrogate the way in which culinary practices in the past are understood. The circum-Alpine lake dwelling complex of central Europe includes hundreds of archaeological sites dating to the Neolithic, Bronze, and Iron Age; many of these sites are known for exceptional preservation of organic material due to a waterlogged, anaerobic environment. Robenhausen, located in eastern Switzerland was one of many lake dwellings discovered in the ...


Social Anxiety Reduction In The Context Of Social Modeling Utilizing A Placebo Alcohol Beverage, Kyle K. Jackson Dec 2019

Social Anxiety Reduction In The Context Of Social Modeling Utilizing A Placebo Alcohol Beverage, Kyle K. Jackson

Theses and Dissertations

Alcohol misuse and elevated social anxiety are found to be highly comorbid, and being exposed to social models consuming alcohol can increase one’s consumption. Yet no research has thus far examined whether the internal experience of alcohol consumption (e.g., social anxiety reduction) can also be transmitted via social modeling. This bar-lab study examined the impact of social modeling behavioral cues of social anxiety on emerging adult drinkers. It was hypothesized that those exposed to a social model experiencing an apparent social anxiety reduction from drinking would themselves report lessened state social anxiety following a placebo drink, and that ...


The Effect Of Organizational Tenure, Bargaining Unit Status, And Union Membership On Local Government Employee Public Service Motivation, Ty Ryburn Dec 2019

The Effect Of Organizational Tenure, Bargaining Unit Status, And Union Membership On Local Government Employee Public Service Motivation, Ty Ryburn

Theses and Dissertations

Two of the largest challenges public organizations face in motivating their workforces are the aging workforce and the strong union influence (Lavigna, 2014). On June 27, 2018, the United States Supreme Court ruled in Janus vs. AFSCME to abolish agency fees, and gave public service employees in bargaining units the right to choose whether they want to pay union dues or pay no fees at all.

In examining the unique motivational factors of employees in the public sector, Perry and Wise (1990) developed a theory called Public Service Motivation (PSM). Later, Perry (1996) developed a survey instrument which despite criticism ...


The Feedback-Related Negativity Is A Time-Dependent Brain Mechanism That Facilitates Aversive Learning: Implications For The Reinforcement Learning Frn Hypothesis, Eric Rawls Dec 2019

The Feedback-Related Negativity Is A Time-Dependent Brain Mechanism That Facilitates Aversive Learning: Implications For The Reinforcement Learning Frn Hypothesis, Eric Rawls

Theses and Dissertations

Organisms encode rewarding and aversive experiences through reinforcement learning, capitalizing on prediction errors (PEs), which adapt action strategies over time. Computational theories are explicit that PE signals should update action weights continuously over the course of a behavioral task, an important time-dependent variation that is eschewed in traditional neuroscience studies that average over large numbers of trials. I examined variation in reaction times and feedback-locked cortical activity over time as a function of PE to critically examine theories indicating that PE signals drive time-dependent learning. We recorded EEG while participants completed a novel reinforcement task that varied prediction error on ...


Essays In Financial Economics, Kamilla Kasymova Dec 2019

Essays In Financial Economics, Kamilla Kasymova

Theses and Dissertations

This dissertation consists of three essays concerning financial economics.

In the first essay, I focus on the role of the life insurance in the financial markets and the factors that drive the development of life insurance industry. The essay examines the causality of the banking sector development on the development of the life insurance market measured by the total premiums received by life insurers using panel estimation for about 90 countries over the period 1996-2010. I employ the dynamic System Generalized Method of Moments estimation technique to resolve the endogeneity problem between the development of the life insurance and the ...


Motivation Is Deficient In The Spontaneously Hypertensive Rat (Shr), A Rodent Model Of Adhd: Evidence From An Operant Breakpoint Paradigm, Amanda S. Nazario Dec 2019

Motivation Is Deficient In The Spontaneously Hypertensive Rat (Shr), A Rodent Model Of Adhd: Evidence From An Operant Breakpoint Paradigm, Amanda S. Nazario

Theses and Dissertations

Attention Deficit Hyperactivity Disorder (ADHD) is one of the most commonly diagnosed childhood neurobehavioral disorders. ADHD is characterized by three core behavioral deficits (hyperactivity, inattention, and impulsivity) that significantly hinder the daily functioning of those diagnosed. Furthermore, children with ADHD have problems with motivation and often require larger, more frequent rewards in order to complete a task. In this study, we used the Spontaneously Hypertensive Rat (SHR), a rodent model of ADHD that exhibits all the core deficits of the disorder. The goal of the current study was to further validate the SHR as a model of ADHD by training ...


Arkansas' Teachers Perceptions Of The Common Core State Standards, Alexandra Vasile Dec 2019

Arkansas' Teachers Perceptions Of The Common Core State Standards, Alexandra Vasile

Theses and Dissertations

The Common Core State Standards were created in 2009 in order to unify the states’ own standards and provide a specific set of learning goals for English Language Arts and Mathematics that students should achieve by the end of each schooling year, to ensure an increased college and career readiness, by emphasizing skills rather than specific content knowledge. The current quantitative study seeks to determine the perceptions that Arkansas teachers have towards the Common Core Standards by posing two main research questions: 1. Do Arkansas teachers perceive the Common Core State Standards as beneficial to their students? and 2. Do ...


Strategies To Improve Forage Utilization By Sheep Offered Forage Mixtures, Valens Niyigena Dec 2019

Strategies To Improve Forage Utilization By Sheep Offered Forage Mixtures, Valens Niyigena

Theses and Dissertations

In the first experiment, alfalfa and novel endophyte-infected tall fescue (NE+) forages were harvested after a killing frost, then mixed to formulate 4 different treatments; alfalfa alone, 67% alfalfa +33% fescue, 33% alfalfa + 67% fescue, or 100% fescue. After 3 months of storage as silage, Dorper ewe lambs (n = 20; mean BW = 34.7 ± 6.65 kg) were fed silage for ad libitum consumption, using 5 animals per treatment. Increasing the proportion of NE+ tall fescue improved (P < 0.05) silage total acids and lactic acid concentrations and decreased silage ammonia concentration. Digestible dry matter and organic matter intake and nitrogen utilization parameters decreased with increasing inclusion of NE+ in diet. In the second experiment, 16 Dorper ewe lambs (41.8 ± 4.61 kg BW) were assigned to 4 different treatments; alfalfa silage alone (0 g/kg; CONT) or alfalfa silage mixed with chopped sericea lespedeza (SL) hay to provide 90 (LOW), 180 (MED), or 270 g/kg SL (HIGH) on a dry matter basis in a randomized complete block design experiment with 2 period to provide 4 observations per treatment for each experimental period. Increasing the proportion of sericea lespedeza in the diet decreased dry matter and organic matter digestibility but did not affect feed intake. Fecal nitrogen (g/kg N intake) increased linearly (P < 0.01) while urinary N (g/ day and g/ kg of N intake) tended to decreased linearly and quadratically (P ≤ 0.1) with increasing the proportion of SL in diet. In the third experiments, 16 gestating Dorper ewe lambs (49.1 ± 4.61 kg BW) were allocated to 4 treatments; alfalfa silage alone (0% g/kg; CONT) or alfalfa silage mixed with lablab purpureus(LP) hay to provide 90 (LOW), 180 (MED), or 270 g/kg LP (HIGH) on a dry matter (DM) basis, in a randomized complete block design experiment with a total 8 replication per treatment. Supplementation of LP in diet increased quadratically (P ≤ 0.04) forage dry matter, organic matter intake, digestible dry matter and digestible organic matter intake (P < 0.05). Nitrogen apparently absorbed and urinary N both decreased linearly (P < 0.01) with adding more LP hay in diet. Harvesting and mixing alfalfa and fescue after a killing frost improved silage fermentation characteristics and supplementation of tannins from SL and polyphenol from LP altered N excretion.

Key words: lablab, sericea lespedeza, alfalfa silage, nitrogen, sheep.


Schooling And Civic Behavior: A Global Perspective, Ian Kingsbury Dec 2019

Schooling And Civic Behavior: A Global Perspective, Ian Kingsbury

Theses and Dissertations

National governments confront different challenges to the goal of creating model citizens, as well as different ambitions in the type of citizen that they wish to create. The United States government faces a tension in determining the role of education in shaping the social order. As a liberal democracy that extols the virtue of individual liberty, the United States should allow educational pluralism to flourish. Paradoxically, however, a nation of immigrants might require an education system that turns students into “proper Americans” who honor the precepts of liberty, equality, and self-government. I draw from domestic and international studies to inform ...


Methods To Evaluate Ruminant Animal Production Responses, Jose Manuel Diaz Gomez Dec 2019

Methods To Evaluate Ruminant Animal Production Responses, Jose Manuel Diaz Gomez

Theses and Dissertations

In experiment 1, 80 steers (197.0 kg initial body weight; BW for fall, 116.9 kg for spring), were stocked at 2.45 and 4.1 calves/ha in fall and spring, respectively in 16 tall fescue pastures [fall ergovaline (EV) = 1,475 ppb and spring EV = 1,173 ppb] under 2 treatments, mineral (MIN) (n = 8) and cumulative management (CM) (n = 8). Forage allowance did not differ (P = 0.76) between CM and MIN during fall but differed during spring (P ≤ 0.05, 2.55 vs. 3.22 kg DM/kg BW, for MIN and CM, respectively). For ...


Interpreting Potential Groundwater Policies Through Modeling Of Market And Non-Market Benefits And Costs, Grant H. West Dec 2019

Interpreting Potential Groundwater Policies Through Modeling Of Market And Non-Market Benefits And Costs, Grant H. West

Theses and Dissertations

Current policies leveraging financial incentives and improved irrigation efficiency to mitigate groundwater scarcity have not proven to curtail trends of resource depletion. Groundwater benefits cannot be appropriately valued solely on market forces, and so deeper policy consideration is warranted under a framework that considers the importance of groundwater across all its values to society. Understanding time preferences for groundwater management and preferences for alternative policies is vital to inform efficient policies. Furthermore, climate change remains politically controversial yet has important consequences for critical groundwater resources and their sustainable long-term management. Proliferating policy narratives concerning climate change could influence the way ...


Changes In Cortical Processing Following Unilateral Visual Cortex Deafferentation, Matthew Gannon Dec 2019

Changes In Cortical Processing Following Unilateral Visual Cortex Deafferentation, Matthew Gannon

Theses and Dissertations

After the loss of inputs, cells in visual cortex adapt and begin representing space beyond their classical receptive fields. This ability for functional reorganization is a phenomenon known as neuroplasticity. Homonymous hemianopia is a unique case of this scenario that results from hemispheric deafferentation, or when all visual inputs in to one hemisphere of the brain are lost. This condition occurs due to unilateral damage of the post-chiasmatic geniculo-striate pathway, the network that carries visual information from one side of visual space to the visual cortex for processing. Damage to this pathway causes perceptual blindness in the side of space ...


Created For Connection: The Impact Of A Faith-Based Christian Marriage Enrichment Program, Chad N. Imhoff Dec 2019

Created For Connection: The Impact Of A Faith-Based Christian Marriage Enrichment Program, Chad N. Imhoff

Theses and Dissertations

The purpose of this study was to explore the effects of Created for Connection (CFC), a faith based marriage enrichment program on relationship satisfaction, adult attachment style and adult attachment behavior. This study further adds to the existing knowledge base related to faith-based programs delivered in an intensive weekend format (Johnson & Sanderfer, 2016). Participants were volunteers from the local community who identified as Christian. To ascertain the effectiveness of CFC, three self-report measures were administered at three different intervals: two weeks before the program, two weeks following the program and a six-week follow-up. I measured attachment anxiety, attachment avoidance, attachment behaviors and relationship satisfaction. I compared results using four repeated measure ANOVAs. CFC did have a statistically significant effect on relationship satisfaction and on attachment avoidance. Previous literature highlights the need for research on this type of intervention as well as the importance of the marriage relationship (Anderson, 2014; Berger & Hannah, 2014; Cole & Cole, 1999; Markman & Rhoades, 2012; Worthington, Johnson, Hook, & Aten, 2013). This research offers some insights as to the effects of this program and also establishes a base from which further research can be done on CFC.


The Social Construction Of Black Fatherhood In Responsible Fatherhood Policies, Azaliah B. Israel Dec 2019

The Social Construction Of Black Fatherhood In Responsible Fatherhood Policies, Azaliah B. Israel

Theses and Dissertations

Responsible fatherhood legislation bridges the gap between two explicit family policies in order to serve fathers: The Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) of 1996 and the Child Support Enforcement Act of 1975. Historically, these two polices have been racialized and discourse surrounding them may contribute to negative cultural formula stories about the primary targets of responsible fatherhood programs: low-income Black fathers.

The first article addresses the question of whether and how congressional discourse disrupts or legitimizes negative cultural formula stories about Black fatherhood. This study examines congressional discourse during hearings on fatherhood legislation. Members of congress legitimized ...


The Cognition Of Controversy: Examining Policy Elites’ Narrative Cognition And Communication Around Hydraulic Fracturing Practices In The U.S., Rachael M. Moyer Dec 2019

The Cognition Of Controversy: Examining Policy Elites’ Narrative Cognition And Communication Around Hydraulic Fracturing Practices In The U.S., Rachael M. Moyer

Theses and Dissertations

The use of hydraulic fracturing (HF) technologies to extract oil and gas in the United States has sparked contentious policy debates, producing inconsistent and inefficient policies that have done little to address the impacts of HF in any comprehensive way. Debates are accompanied by competing policy narratives that position HF as either an environmental threat or an economic opportunity, but little is known about how policy narratives around HF are used by individuals. This dissertation systematically examines how individuals cognitively internalize elements of competing HF policy narratives. Organized into three empirical chapters, this dissertation analyzes narrative cognition (Jones, Shanahan, and ...

Establishing An Ideal Inclusion Rate Of Fermented Soybean Meal And Sodium Butyrate On Growth Performance, Complete Blood Cell Count, And Nutrient Utilization In Nursery Pigs, Kristopher A. Bottoms

Theses and Dissertations

To evaluate increasing levels of sodium butyrate (SB) in nursery diets on growth performance (Experiment 1 & 2), complete blood cell count (Experiment 2), and the optimal level of fermented soybean meal for maximum performance in weanling pigs (Experiment 3), weaned pigs were blocked with initial body weight (BW) and allotted to dietary treatments. Treatments were: 1) Control (C) moderately complex corn-soybean-meal based supplemented with 0.05% benzoic acid (BA), but devoid of SB; C diet supplemented with 0.05%, 0.10%, or 0.15% SB (Experiment 1). Treatments in experiment 2 consisted of 1) a moderately complex corn-soybean-meal based diet devoid of SB and BA (NC), 2) The NC diet supplemented with 0.5% BA, 3, 4 and 5) NC diet supplemented with 0.5% BA and 0.05%, 0.10% or 0.15% SB, respectively. Treatments in experiment 3 consisted of 1) a fermented soybean protein-poultry by-product diet (C), 2, 3, and 4) C diet was ...
