Influence Of Different Breeds Of Pigs To The Natural Succession, H D. Matthes, A.C D. Micklich, G Dietl, H Mohring, W Jentsch

IGC Proceedings (1993-2023)

The aim of this study was to find out the effect of pigs on the natural succession. We used 4 different breeds of pigs for our investigations. Because of the grazing behaviour and their rooting activity the total number of plants increased up to 30%. But the vegetation quickly returned to conditions prior to rooting, if the rooting activity fails to happen. Rooting activity of pigs on floodplain soil and following grazing in the next spring after rooting permits seeds of different species of plants to germinate and develop in the plant free areas. These plants often have little chance …

Left Ventricle Function And Post-Transcriptional Events With Exercise Training In Pigs, Stephanie L. Samani, Shayne C. Barlow, Lisa A. Freeburg, Traci L. Jones, Marlee Poole, Mark A. Sarzynski, Michael R. Zile, Tarek Shazly, Francis G. Spinale

Faculty Publications

Background

Standardized exercise protocols have been shown to improve overall cardiovascular fitness, but direct effects on left ventricular (LV) function, particularly diastolic function and relation to post-transcriptional molecular pathways (microRNAs (miRs)) are poorly understood. This project tested the central hypothesis that adaptive LV remodeling resulting from a large animal exercise training protocol, would be directly associated with specific miRs responsible for regulating pathways relevant to LV myocardial stiffness and geometry.

Methods and results

Pigs (n = 9; 25 Kg) underwent a 4 week exercise training protocol (10 degrees elevation, 2.5 mph, 10 min, 5 days/week) whereby LV chamber stiffness (KC) …

Evaluation Of Increasing Levels Of Mycotoxin-Containing Corn Fines On Diet Choice And Growth Performance Of Nursery Pigs, Duncan B. Paczosa

Theses and Dissertations--Animal and Food Sciences

Pigs fed mycotoxin contaminated diets at high concentrations will result in a detriment to health and performance. An initial study and a follow-up study were conducted to evaluate the effects of feeding increasing levels of mycotoxin-containing corn fines on growth performance, diet preference of pigs, and two possible mitigants.

The initial study was a 3 x 2 factorial containing three levels of fines (0, 10, and 20%, Diets 1-3, respectively) and either 0 ppm (Diets 1-3) or 40 ppm boron (Diets 4-6; Diets 4-6 were Diets 1-3, respectively, plus boron) as sodium tetraborate decahydrate as a possible mitigant. In this …

Evaluation Of Human Microbiota-Associated (Hma) Porcine Models To Study The Human Gastrointestinal Microbiome, Nirosh D. Aluthge

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Research conducted in the past couple of decades has showcased the importance of the gut microbiota in human health and well-being. While many studies have reported on the differences in community membership between a disease state and a healthy state, few have investigated the mechanisms through which an aberrant microbiota contributes to a disease phenotype. One of the primary reasons for this are the many technical and ethical barriers to conducting the necessary studies directly in human individuals. Human microbiota-associated (HMA) porcine models have the potential to become important research tools which can enable the testing of hypotheses regarding host-microbiota …

Testing For Transferred Immunity Of A Universal Influenza Vaccine In Pigs, Rachel Marie Sestak

Honors Thesis

Influenza causes high numbers of illnesses and deaths annually (CDC, 2020). Influenza vaccines prevent these complications by reducing the risk of flu illness between 40-60% (CDC, 2021). However, no vaccination exists for infants under six months old so other methods, such as passive immunity, must be explored. To determine how infants can be protected, we tested the passive transfer of a universal influenza vaccine using a pig model and researched the mechanism of transfer. Four pregnant pigs were vaccinated one time with PBS and one time with HA-129 vaccine and four were vaccinated twice with the HA-129 vaccine. After farrowing, …

Polymeric Nanovaccine Delivery System For Influenza Vaccine, Chaitanya K. Valiveti

Electronic Theses and Dissertations

Vaccines are the most efficient and cost-effective method for preventing illnesses caused by infectious pathogens. Even though the great success of vaccines over decades, the development of safe and robust vaccines is still essential for emerging new pathogens, re-evolving old pathogens, and improving the insufficient protection given by existing vaccines. One of the most critical strategies for developing effective new vaccines is selecting and using a suitable adjuvant or immune stimulant. Immunologic adjuvants are essential for improving vaccine potency by enhancing the immune response of vaccine antigens. The amount of antigen could be spared with improved potency, especially during mass …

The Epigenetics Of Gametes And Early Embryos And Potential Long-Range Consequences In Livestock Species—Filling In The Picture With Epigenomic Analyses, Linkai Zhu, Sadie L. Marjani, Zongliang Jiang

Faculty Publications

The epigenome is dynamic and forged by epigenetic mechanisms, such as DNA methylation, histone modifications, chromatin remodeling, and non-coding RNA species. Increasing lines of evidence support the concept that certain acquired traits are derived from environmental exposure during early embryonic and fetal development, i.e., fetal programming, and can even be “memorized” in the germline as epigenetic information and transmitted to future generations. Advances in technology are now driving the global profiling and precise editing of germline and embryonic epigenomes, thereby improving our understanding of epigenetic regulation and inheritance. These achievements open new avenues for the development of technologies or potential …

The Identification Of Differentially Expressed Genes Between Extremes Of Placental Efficiency In Maternal Line Gilts On Day 95 Of Gestation, Shanice K. Krombeen, Vijay Shankar, Rooksana E. Noorai, Christopher A. Saski, Julia L. Sharp, Matthew E. Wilson, Tiffany A. Wilmoth

Faculty & Staff Scholarship

Background: Placental efficiency (PE) describes the relationship between placental and fetal weights (fetal wt/placental wt). Within litters, PE can vary drastically, resulting in similarly sized pigs associated with differently sized placentas, up to a 25% weight difference. However, the mechanisms enabling the smaller placenta to grow a comparable littermate are unknown. To elucidate potential mechanisms, morphological measurements and gene expression profiles in placental and associated endometrial tissues of high PE and low PE feto-placental units were compared. Tissue samples were obtained from eight maternal line gilts during gestational day 95 ovario-hysterectomies. RNA was extracted from tissues of feto-placental units with …
