Equine Nutrition: Pasture Planning In Nebraska, Emma Vazquez

Honors Theses

This paper describes the rationale behind four infographics on equine nutrition and pasture planning. These infographics are intended to provide Nebraskan horse owners with general advice on setting up and maintaining their pastures. The first three infographics cover pasture basics when building, pasture care, and ideal grass types. These grass types are further broken down between Western and Eastern Nebraska. Additionally, the fourth infographic gives some insight into why forage is a staple in the equine diet based on the digestive system.

All four infographics have been posted to the University of Nebraska-Lincoln’s Horse Program social media pages in an …

Effects Of Probiotic Supplementation On Growth And Health Of Pre-Weaned Dairy Calves, Lily Bello

Honors Scholar Theses

Dairy calf immune development leaves calves susceptible to illness during the pre-weaned stage of life. Previous studies have shown that the use of probiotics during this time may result in increased growth rates and decreased incidence of illness, particularly diarrhea and scours. We hypothesized that by providing probiotics during the time from birth until weaning, calves on study would experience similar growth and health benefits. Neonatal calves (N=32) were provided milk replacer three times daily, with half of the calves receiving Probios® supplements mixed in with their first morning feeding. Growth and health measurements were collected weekly. Probiotic administration significantly …

Pilot Testing A Qualitative Methodology To Evaluate The Perceived Benefits And Stressors Of Sole-Dog Ownership In Full-Time College Students, Emma Williams

Animal Science Undergraduate Honors Theses

The number of individuals acquiring pets is continually increasing, with 71.5% of Americans owning a pet in 2012. Companion animals are a huge source of benefits but owning them can also come with several stressors. However, little research has been conducted on the negative aspects of dog ownership. This pilot test evaluates the perceived stressors and benefits of sole dog ownership in full-time college students. The pilot aimed to hold three focus groups from which qualitative thematic data were collected and quantitative were collected from a demographic survey of participants. Participants were asked a series of questions about sole dog …

Fetal Programming Of Intrauterine Growth Restricted Skeletal Muscle Stem Cell Function, Micah Most

Honors Theses

Intrauterine growth restriction (IUGR) reduces skeletal muscle mass in fetuses and offspring. The objective of this study was to determine if myoblasts (skeletal muscle stem cells) from maternal inflammation induced intrauterine growth-restricted (MI-IUGR) fetuses are less responsive to proliferation-stimulating factors in culture. Ovine MI-IUGR fetal myoblasts were isolated at 125 days of gestational age (dGA, term = 150 dGA), grown for 72 hours in complete growth media spiked with insulin, tumor necrosis factor α (TNFα), or unspiked (basal), and analyzed for ex vivo proliferative capacity via a 2 hour EdU pulse. A second set of myoblasts were differentiated in differentiation …

Animal-Assisted Activities Survey At The University Of Nebraska-Lincoln: Assessing Student Opinions And Determining Possible Implementation Strategy, Emma Winters

Honors Theses

In most situations, animals are not allowed on the University of Nebraska-Lincoln (UNL) campus, including animals used for animal-assisted activities (AAA). Animal-assisted activities have been shown to provide numerous benefits to participants and there could be positive effects to offering AAA at UNL. In order to gauge the opinions of students regarding AAA and how AAA could best be implemented on the UNL campus, a survey was emailed to Animal Science majors and students enrolled in ASCI 271 and ASCI 321 at the University of Nebraska-Lincoln. A request to participate was also included in the weekly College of Agricultural Sciences …

Menageries Multiple: An Introduction To Zoological Multiplicity In The Modern American Zoo, Emily D. Gratke

Scripps Senior Theses

American zoological parks have been sites of intense consumer and scholar interest since their origination in the 20th century. Today, zoos reside at a tenacious hub of ideologies, practices, and priorities contributed to by various stakeholder groups. I propose that the foundational cause of this tension is zoological multiplicity: the theory that through human practices and perceptions, animals can embody multiple identities. Via an exploration of zoological multiplicity in American zoos with specific focus on zoo management, zoogoer, and animal activist stakeholder groups, this project proposes the widespread acknowledgment and understanding of zoological multiplicity as a method to improve animal …

Jcpenney And His Agrarian Animals: The Award-Winning Livestock Of A Department Store Icon, David Kruger

David Delbert Kruger

Widely known for his department store chain, James Cash Penney (1875-1971) greatly contributed to American agriculture through his horse and cattle breeding enterprises. Beginning in 1917, three years after moving to New York City, Penney began using his personal capital to acquire, breed, and sell outstanding animals for agricultural purposes. By the 1920s, his Guernsey dairy herd had earned a worldwide reputation for quality and production, with herd sire Foremost eventually becoming the namesake for one of the largest dairy cooperatives in the United States. By the 1940s, Penney was personally developing award-winning beef cattle herds on the Missouri farm …

Comparison Of Calf-Fed Vs. Yearling-Fed Management For The Estimation Of Carcass Trait Genetic Parameters In Simmental Cattle, Richard G. Tait Jr.

Richard G. Tait Jr.

Selection indexes for feedlot performance have been developed by U.S. beef breed associations to help commercial producers with multiple trait selection decisions. The objective of this study was to evaluate the implications of backgrounding cattle after weaning on selection for feedlot profitability. Carcass data records for 11,011 animals and a three generation pedigree were obtained from the American Simmental Association database. Carcass traits of primary interest in this analysis were marbling score (MARB), 12^th rib fat thickness (CFT), 12^th rib ribeye area (CREA), and hot carcass weight (HCW). Estimated post weaning gain (EPWG) was determined using weaning weight …

Cal Poly Goat Program, Lauren Christensen

Animal Science

The Cal Poly Goat Program was established in the Summer of 2012 to provide vegetation management services on the Cal Poly campus and to allow students to gain hands on experience with goats. Student interest in adding goats as an additional species in the Animal Science Department spurred the realization and development of the program. The department also experienced demand for goats to use for vegetation management at the animal units and around various facilities on campus. The Goat Program integrates Cal Poly’s hands-on, ‘Learn by Doing’ philosophy with sustainable management practices to serve the needs of students as well …
