Early Events In Japanese Encephalitis Virus Infection: Viral Entry, Sang-Im Yun, Young-Min Lee

Animal, Dairy, and Veterinary Science Faculty Publications

Japanese encephalitis virus (JEV), a mosquito-borne zoonotic flavivirus, is an enveloped positive-strand RNA virus that can cause a spectrum of clinical manifestations, ranging from mild febrile illness to severe neuroinvasive disease. Today, several killed and live vaccines are available in different parts of the globe for use in humans to prevent JEV-induced diseases, yet no antivirals are available to treat JEV-associated diseases. Despite the progress made in vaccine research and development, JEV is still a major public health problem in southern, eastern, and southeastern Asia, as well as northern Oceania, with the potential to become an emerging global pathogen.

The Old Versus The New Equestrian Circus: Demonstrating And Promoting Equine Welfare, Veronica Painter

Theses and Dissertations

Circus is an art form that was originally considered as a humanitarian art, promoting equine welfare by shedding a new light on the horse and human relationship. During a time where horses were used for war, work, and transportation; fancy riding and liberty stood as the framework for a new togetherness between man and beast. The animal activist revolution centered on exotic animals in circus, yet the effects of these demanding pressures caused a major blow to the equestrian circus. This comparative study examines possible improvements to the industry in order to keep this art alive. Keeping up with eclectic …

Comparison Of Traditional And Alternative Ingredients On Meat Curing Reactions Using A Model System, Faith Rasmussen

Department of Animal Science: Dissertations, Theses, and Student Research

Consumer’s negative perception of “chemical-sounding” ingredients has increased the use of alternative ingredients. The objective of this study was to determine the effect traditional (sodium nitrite with or without sodium erythorbate) or alternative (celery juice powder with or without acerola cherry powder) curing systems with different ingoing concentrations of sodium nitrite using model meat solutions. Curing systems with reducing agents developed the most cured meat pigment (p < 0.001). Using more than 50 ppm of nitrite did not further increase cured meat pigment (p < 0.001). Curing systems with reducing agents and 50 ppm or greater nitrite had the least residual nitrite (p < 0.001). Alternative curing systems had the most residual sulfhydryl groups when formulated with 100 ppm or more nitrite (p < 0.001). Treatments with reducing agents had greater residual reducing capacity than treatments without reducing agents (p < 0.001). Both alternative and traditional curing systems develop similar cured meat pigment but differences in the nitrosation of cysteine exist.

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim …

What’S At Steak? The Political Discourse Of Emissions Intensity And Implications Of Animal Agriculture, Kalyn Simon

Master's Theses

This thesis analyzes the international discourse of greenhouse gas emissions in relation to livestock production. Specific government ministries, research institutes, and multilateral organizations are framing a new strategy to mitigate emissions by using emissions intensity metrics. Emissions intensity is a ratio comparing emissions produced per unit of animal product as oppose to measuring absolute emissions. This research is acknowledged as a win-win scenario which allows for a reduction of greenhouse gas emissions while continuing production more efficiently. This thesis outlines the emergence of this metric in international discourse and the implications this shift has on the livestock sector globally. Ultimately, …

Relationships Among Beef Cow Productivity Traits And Single Nucleotide Polymorphisms In The Bovine Heat Shock Protein 70 Gene, Ashley Finney

Animal Science Undergraduate Honors Theses

When eukaryotes are exposed to stressors such as heat, toxins, and low oxygen levels, heat shock proteins (HSPs) are synthesized to maintain normal cellular function within the body. Single nucleotide polymorphisms in the heat shock protein 70 (Hsp70) gene have been associated with calving percentage, and Julian calving date in spring-calving crossbred Brahman cows (Rosenkrans, et al., 2010). Our objective was to determine associations between previously identified polymorphisms in the promoter region and coding sequence of the bovine Hsp70 gene and beef cow efficiency. We evaluated productivity traits, including Julian calving date and calving rates, of fall-calving cows at each …

Polymorphisms Of Bovine Hsp90 And Their Implications In Beef Cattle Productivity, Glynn G. Smith

Animal Science Undergraduate Honors Theses

Production of beef cattle represents a $60 billion industry in the United States (USDA, 2015). The American beef cattle industry loses an estimated $370 million annually due to heat stress (St-Pierre, 2003). As of 2003, this was equal to nearly 99 million pounds of beef lost (USDA, 2015). The average American consumed roughly 65 pounds of beef in 2003; this means that the 99 million pounds of beef lost to heat stress would have been enough to feed approximately 1.5 million Americans for an entire year (Barclay, 2012).

Enhancing Quality Of Life Through Foreign Direct Investment In Northern Mozambique, Sarah-Beth Delay

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Foreign Direct Investment (FDI) has the potential to increase economic activity and improve GDP growth in low-income countries, but can hinder economic development (quality of life improvements) if not sustainable and holistic in manner. Africa serves as a host to many cases of FDI focused on economic growth, but not necessarily improving the quality of life for its citizens. FDI has spread throughout the African continent, where many countries are well endowed with natural resources, like minerals and coal. These economies have experienced rapid GDP growth with few benefits reaching citizens of the host country. Mozambique is a low-income country …

Effects Of Environmental Enrichment On Behavior In A Domestic Goat Herd, Stephanie Peramas

Senior Honors Projects

Animal welfare is one of the most important parts of animal management. Apart from other measures of good animal welfare, like being in good health, animal behavior can be indicative of the animal’s internal state and is often one of the first signs of improper welfare. Stereotypies, or stereotypic behavior, are commonly viewed as a symptom of improper animal welfare. Unenriched, or barren, environments associated with farmed livestock have long been associated with inducing stereotypic behavior. The addition of precise enrichment to the animals’ environment is a common remedy for stereotypic behavior. With respect to stereotypic goat behavior, few empirical …

Dissection Of Qtl On Host Chromosome 12 Uncovers Candidate Gene And Missense Polymorphism Associated With Porcine Circovirus 2 Susceptibility, Lianna Rayne Walker

Department of Animal Science: Dissertations, Theses, and Student Research

Porcine circovirus 2 (PCV2) is a small single stranded DNA virus responsible for a group of detrimental diseases referred to as Porcine Circovirus Associated Diseases (PCVAD). Observed variation in incidence and severity of PCVAD between pigs suggests a host genetic role in facilitating PCV2 pathogenesis. This study builds on prior research by Engle et al. (2014), who performed a large-scale genome-wide association study of 974 crossbred pigs experimentally infected with a PCV2b isolate and provided evidence of a host genetic role in PCV2 viremia, immune response, and growth. Two major Quantitative Trait Loci (QTL) were identified for viral load located …

Professional Agricultural Workers Journal

The study assessed the characteristics and practices of small livestock producers, emphasizing production and processing. Data were obtained from a convenience sample of seventy small producers from selected counties in Florida, and analyzed using descriptive statistics, including chi-square tests. The socioeconomic characteristics showed that part-time producers, White producers, middle-aged producers, fairly educated producers, and moderate-income producers dominated the group. A majority of the producers practiced rotational grazing, fed a combination of forage and concentrate, and less than half conducted soil tests regularly. Moreover, over half had parasite problems and treated them primarily with anthelmintics. Nearly all producers sold animals live, …

Study On The Relationship Between Expression Patterns Of Cocaine-And Amphetamine Regulated Transcript And Hormones Secretion In Porcine Ovarian Follicles, Pengfei Li, Jinzhu Meng, Jiongjie Jing, Qingling Hao, Zhiwei Zhu, Jianbo Yao, Lihua Lyu

Faculty & Staff Scholarship

Background: Cocaine-and amphetamine regulated transcript (CART) is an endogenous neuropeptide, which is widespread in animals, plays a key role in regulation of follicular atresia in cattle and sheep. Among animal ovaries, CART mRNA was firstly found in the cattle ovaries. CART was localized in the antral follicles oocytes, granulosa and cumulus cells by immunohistochemistry and in situ hybridization. Further research found that secretion of E2 was inhibited in granulosa cells with a certain dose of CART, the effect depends on the stage of cell differentiation, sug- gesting that CART could play a crucial role in regulating follicle atresia. The objective …
