Molecular Investigation Of Tick-Borne Pathogens In Feral Swine (Sus Scrofa) From Seven Us States, Sofiane Aiche

Masters Theses

Feral swine (Sus scrofa) have been proposed as part of the lifecycles of multiple tickborne pathogens (TBP). This is a result of the increase in feral swine populations and increased tick populations and geographic ranges. Few surveys exist on the TBP relevant to human and wildlife of feral swine in the US. The aim of this study is to investigate the prevalence of 10 TBP: Anaplasma spp., Borrelia spp., Cytauxzoon felis, Hepatozoon spp., Babesia spp., Mycoplasma spp., Trypanosoma cruzi, Toxoplasma gondii, Yersinia pestis, and Rickettsia spp. A total of 87 feral swine blood samples …

Evaluation Of Dietary Fiber Technologies In Sow Diets, Garrin Shipman

Electronic Theses and Dissertations

Various technologies and alternative ingredients are being developed to increase the nutrient value of fibrous feedstuffs, improve animal performance, and promote sustainable swine production. Fiber-degrading enzymes have been extensively studied in growing pigs, with few studies focused on gestating sows. When considering gestating sows have greater energy digestibility of fibrous feedstuffs than grower pigs, the efficacy of fiber-degrading enzymes needs to be determined for implementation in commercial sow diets. As fiber inclusion in gestation diets benefits sow performance, corn dried distiller grains with solubles (DDGS) are a candidate fiber source for gestation alternative energy ingredient. Functional fibers, such as yeast …

Two randomized complete block design experiments were conducted to: 1) examine the effects of soybean meal with or without additional soybean hulls in replacement of modified corn distillers grains plus (MDGS) solubles on growth performance efficiency of dietary net energy utilization and carcass traits responses in finishing beef steers, 2) determine if partial or complete replacement of dried distillers grains plus solubles (DDGS) with solvent-extracted soybean meal (SBM) in diets based upon high-moisture ensiled corn influences growth performance, efficiency of dietary net energy utilization, sera urea-N (SUN) concentrations, or carcass traits in finishing beef steers. Experiment 1 was a 118-d …

Increasing Soy Products Inclusion In Swine Diets To Improve Growth Performance, Health, And Pork Quality, Ashir Foreman Atoo

Electronic Theses and Dissertations

Despite its excellent nutritional profile, soybean meal (SBM) is limited in nursery pig diets due to its anti-nutritional factors (ANFs), which young pigs tolerate poorly. In the first study, strategies to mitigate these effects included supplementation with enzymes, alone or with acidifiers. A total of 240 weaned pigs (5.9 ± 0.8 kg average body weight [BW]) were assigned in randomized complete block design to five dietary treatments: low, medium, or high SBM diets, high SBM with multienzyme, and high SBM with multienzyme plus acidifier. Diets were fed in three phases: phase 1 (0–1 weeks), phase 2 (1–3 weeks), and phase …

Translocations Of North American Bison Across Large Climatic Gradients: Impacts On Thermoregulation, Body Size, And Helmintic Infection, Hayden Wolfe

Electronic Theses and Dissertations

Every year, one-eighth of all North American bison (Bison bison) are translocated, often across large climatic gradients. Over the last 16 years bison have been translocated from Wind Cave National Park in South Dakota to establish six herds across the United States central grasslands in Iowa, Missouri, Illinois, Indiana, and Kansas. Influence of climatic gradients on herd-level thermoregulation, body size, and helmintic infection were evaluated. Overall, 1174 thermal images and 1050 fecal samples were collected between 2021 and 2023. Physiological heat flux was used to measure thermoregulation, asymptotic body mass (ABM) was used for body size, and helminth genera abundance …

Beef Hot Carcass Weight Influences Proteolysis, Clay J. Carlson

Electronic Theses and Dissertations

The objective of this thesis was to determine the influence of beef hot carcass weight on proteolysis to better understand early postmortem proteolysis. Beef tenderness formation is influenced by various factors, such as temperature decline and proteolysis. Limited focus has been given to the effects of carcass weight on proteolysis. This study aimed to investigate the influence of increased beef hot carcass weight (HCW) on proteolysis of four muscles (serratus ventralis, longissimus thoracis, longissimus lumborum, and semitendinosus) during early postmortem aging times. Beef steers (n =12) were harvested and categorized into two weight groups: lightweight (LW; HCW = 349 ± …

Improving Stream Connectivity In South Dakota, Colton Rainier Curtis

Electronic Theses and Dissertations

Stream connectivity is crucial for fish movement and genetic diversity in fragmented landscapes. Road-crossings often act as barriers, disrupting hydrology and isolating fish populations. The Southeast Aquatic Resources Partnership (SARP) has developed rapid road-crossing assessment protocols and tools to prioritize restoration projects. However, managers lack tools for planning, directing, and initiating roadcrossing assessments. Managers also require modeling approaches to effectively identify and monitor road-crossings across dynamic stream networks. Presented here is a case study offering a roadmap for effective implementation of collaborative road-crossing assessments and prioritization of remediation projects, alongside an exploration of predictive modeling approaches to identify problematic crossings …

Developing Resources To Foster Farmed Animal Agency In Sanctuary Education, Emily Tronetti

Antioch University Dissertations & Theses

Farmed animal sanctuaries provide lifelong care to formerly farmed animals. Many strive to educate their community about farmed animals and promote more compassionate lifestyles, such as veganism. Important to this is cultivating empathy and concern for the well-being of individual farmed animals. Essential to well-being is agency, which is the capacity of a living being to engage with their environments and to make choices for themselves. Farmed animals outside of sanctuaries have had their agency systematically suppressed and denied. Sanctuary educators can bring awareness to this and inspire alternative, agency-centered relationships with not only farmed animals but all living beings. …

Studying Redtail And Silver Surfperch In Sandy Beach Surf Zones With Mpas In Humboldt County, California, Usa, Noah G. Angell

Cal Poly Humboldt theses and projects

The sandy beach surf zone (SBSZ) represents an ecologically, economically, and culturally important marine habitat around the world. Despite its significance, the SBSZ has been historically underrepresented in marine and coastal ecology research. This in turn has caused many inshore marine species that prefer this habitat to be largely ignored. Two particular species, the Redtail surfperch Amphistichus rhodoterus and the Silver surfperch Hyperprosopon ellipticum, have not been well studied in the PNW region . There are merely three studies conducted on the Redtail surfperch in the Pacific Northwest region and the Silver surfperch has received even less research attention with …

CCPO Publications

Western boundary currents (WBCs) adjacent to subtropical continental shelves (STCSs; between ~25° and 35° latitude; Figure 1) transport heat, nutrients, and biota poleward along the western margins of major ocean basins, interacting with the continental margins and influencing their physics and biology. Eddies and meanders along the shelf edge upwell deep, nutrient-laden water that can be advected onto the adjacent shelves with a corresponding export of particle-rich shelf water (e.g., Lee et al., 1991; Kimura et al., 1997; Campos et al., 2000; Roughan and Middleton, 2002, 2004; Lutjeharms, 2006; Savidge and Savidge, 2014).

Diel Vertical Migration Rates Of The Dinoflagellate Species Margalefidinium Polykrikoides In A Lower Chesapeake Bay Tributary, S. Clayton, Jacqueline B. Chrabot, Michael Echevarria, Leah Gibala-Smith, Kathryn Mogatas, Peter Bernhardt, Margaret R. Mulholland

OES Faculty Publications

Margalefidinium polykrikoides is a mixotrophic dinoflagellate harmful algal bloom (HAB) species that blooms annually in the lower Chesapeake Bay. M. polykrikoides undertakes a diel vertical migration (DVM) which may give it a competitive advantage over purely phototrophic organisms who cannot access deeper nutrient pools and allow it to form large toxic blooms. Laboratory-based estimates of M. polykrikoides’ DVM rates suggest that it is one of the fastest known dinoflagellate swimmers and understanding this behavior is likely important for modeling and predicting M. polykrikoides blooms. However, to date, no field-derived estimates of M. polykrikoides’ DVM rates have been made in the …

Ticks (Acari: Ixodidae) Infesting Cattle In Coastal Kenya Harbor A Diverse Array Of Tick-Borne Pathogens, Joseph Wang Ang A. Oundo, Shewit Kalayou, Quirine Ten Bosch, Jandouwe Villinger, Constantianus J.M. Koenraadt, Daniel Masiga

All Peer-Reviewed Publications

Ticks and the microbes they transmit have emerged in sub-Saharan Africa as a major threat to veterinary and public health. Although progress has been made in detecting and identifying tick-borne pathogens (TBPs) across vast agroecologies of Kenya, comprehensive information on tick species infesting cattle and their associated pathogens in coastal Kenya needs to be updated and expanded. Ticks infesting extensively grazed zebu cattle in 14 villages were sampled and identified based on morphology and molecular methods and tested for the presence of bacterial and protozoan TBPs using PCR with high-resolution melting analysis and gene sequencing. In total, 3,213 adult ticks …

Research outputs 2022 to 2026

Marsupials give birth to immunologically naïve young after a relatively short gestation period compared to eutherians. Consequently, the joey significantly relies on maternal protection, which is the focus of the present review. The milk and the pouch environment are essential contributors to maternal protection for the healthy development of joeys. In this review, we discuss bioactive components found in the marsupial pouch and milk that form cornerstones of maternal protection. These bioactive components include immune cells, immunoglobulins, the s100 family of calcium-binding proteins, lysozymes, whey proteins, antimicrobial peptides and other immune proteins. Furthermore, we investigated the possibility of the presence …

Softening And Cross-Susceptibility: Exposure To Heat And Desiccation Reduces Future Stress Tolerance In An Insect, Lauren Harter

University of the Pacific Theses and Dissertations

The frequency and duration of environmental stressors, such as heat waves and drought, will continue to grow due to ongoing climate change, thereby increasing the likelihood that organisms will experience stressors consecutively. Exposure to one stressor can improve or impair future tolerance to the same stressor (i.e., hardening or softening, respectively), or enhance or reduce future tolerance to a different stressor (i.e., cross-protection or cross-susceptibility, respectively). Understanding whether stress improves or impairs animals’ abilities to withstand future stressors is critical for determining the physiological sensitivity of animals to ongoing climate change. Here, I evaluated the responses to consecutive heat and …

Trichechus manatus is one of 3 recognized extant species of manatees of the mammalian Order Sirenia. Currently, it is known by various vernacular names, none of which are descriptive of its biology and known distribution. This lack of standardization has led to confusion and miscommunication, hindering conservation efforts for this species. We propose standardizing the vernacular names used to refer to the species and its 2 subspecies based on appropriate geographical characterization in English, Spanish, French, Dutch, and Portuguese, respectively: “American Manatee”, “Manatí de las Américas”, “Lamantin d’Amérique”, “Amerikaanse Lamantijn”, and “Peixe-boi das Américas” for T. manatus; “Florida Manatee”, “Manatí …

Immune Outcomes Affected By Selection For Parasite Resistance In Katahdin Sheep, Kelsey Lynne Bentley

Graduate Theses, Dissertations, and Problem Reports (ETD)

Our understanding of the complex connection between selection for parasite resistance and the overall health outcomes in livestock is unclear. This study investigates the impact of post-weaning fecal egg count (PFEC) estimated breeding values (EBV) on health outcomes and immune responses in Katahdin sheep. Selection for PFEC, favoring Low-PFEC lambs, not only affects survivability to weaning but also suggests broader implications for immunity beyond parasite resistance. The effect of PFEC EBV on antibody production in response to vaccination against Clostridium perfringens type C&D and tetanus toxoid (CD&T) revealed a stepwise decrease in immunoglobin (IgG) from Low-PFEC to High-PFEC groups upon …
