Respiratory Disease In Bighorn Sheep: A Varied Investigation Of Immunization, Transmission, And Detection, Katelin Frerichs
Respiratory Disease In Bighorn Sheep: A Varied Investigation Of Immunization, Transmission, And Detection, Katelin Frerichs
Electronic Theses and Dissertations
Respiratory disease has historically been recognized as a limiting factor to wild bighorn sheep (Ovis canadensis) herds throughout North America with epizootics resulting in large-scale die offs and reductions in recruitment. The primary etiologic agent associated with pneumonia outbreaks in bighorn sheep is Mycoplasma ovipneumoniae. This bacterial pathogen is frequently carried asymptomatically by domestic sheep (Ovis aries) and goats (Capra hircus); however, when these domestic hosts come in contact with and spread this pathogen to bighorns, the disease can cause epizootics and large-scale mortality. Domestic sheep strains are more commonly detected in bighorn sheep than domestic goat strains, and previous …

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 …

Evaluation Of A Novel Corn Fermented Protein Ingredient, Probiotics, And Postbiotics On Nursery Pig Growth Performance And Gut Health, Juan F. Castillo Zuniga
Electronic Theses and Dissertations
Weaning is a necessary step in pig production. After weaning, pigs are subjected to various nutritional, psychological, and environmental stresses. The weaning period is an important period for the intestinal development of the pig. During this time, digestion, immunity, metabolism, and various other aspects of the pig change rapidly. Therefore, providing high-quality feed ingredients is crucial to encourage the newly weaned pig to start consuming solid feed. Two independent studies were conducted to determine if the inclusion of: 1) corn fermented protein (CFP) or 2) probiotics or postbiotics impact nursery pigs' growth performance and gut health. The first experiment utilized …

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
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 …
Identification And Characterization Of Three Novel Rumen Bacterial Species In Sheep Fed A Concentrate Diet, Reid Frederick Anema
Identification And Characterization Of Three Novel Rumen Bacterial Species In Sheep Fed A Concentrate Diet, Reid Frederick Anema
Electronic Theses and Dissertations
Sheep production in the United States is a popular venture for both small farmers and large enterprise owners, as there is a market for end products such as wool and meat. One major factor of raising sheep is nutrition as an adequate diet will allow an animal to reach its full genetic potential for growth. With that in mind, the composition of the diet must be formulated to benefit the animal. Ruminants have the ability to use a variety of plants that are often inedible for humans to create products that humans can consume. These varying feedstuffs, whether they include …

Human–Wildlife Interactions
Feeding management can be a good strategy for avoiding wildlife–vehicle collisions (WVCs), which are a worldwide concern. In this study, we aimed to identify grass species that capybaras (Hydrochoerus hydrochaeris) reject as feeding material. These species could be planted to make roadsides less attractive to capybaras and, consequently, decrease WVCs involving this species. We planted 3 grass species (Brachiaria decumbens cv. Basilisk, B. hybrid Mavuno, and Zoysia japonica) in 4 blocks, applying a randomized-complete blocks design. The first 2 species we assumed would be rejected, since some animals do not consume them due to their high …

Multi-Year Effectiveness Of Pzp-22 In Free-Roaming Suburban White-Tailed Deer, Allen T. Rutberg, Kali M. Pereira, Kayla A. Grams, John W. Turner Jr.
Human–Wildlife Interactions
To address the challenge that is posed to the use of fertility control to mitigate human–deer (Cervidae) conflicts by the need to regularly re-inoculate free-roaming animals, we captured, ear-tagged, and hand-injected 68 individual adult female white-tailed deer (Odocoileus virginianus) with the PZP-22 immunocontraceptive vaccine from February through April, 2014 to 2017, in the Village of Hastings-on-Hudson, New York, USA. Approximately 2.5 years after initial treatments, we booster-darted 29 of the previously treated females with either PZP-22 or native PZP (ZonaStat-D). We observed fawn production between 2014 and 2021. The combination of initial PZP-22 hand-treatments followed by single dart-delivered PZP …

Efficacy Of A Laser As A Starling Deterrent And Its Effect On Lactating Dairy Cow Behavior, Callan A. Lichtenwalter, Marcos Marcondes, Kyle R. Taylor, Craig Mcconnel, Amber Adams Progar
Human–Wildlife Interactions
European starlings (Sturnus vulgaris) cause damage (including structural damage) on dairies, eat cattle feed, and can potentially spread disease through their fecal matter. Deterring starlings from dairies without affecting cow (Bos taurus) welfare is vital, and lasers have been effective starling deterrence tools in urban roosts and in some crops. To evaluate if the use of lasers on dairies would affect starling use of freestall barns as night roosts, or lactating cow behavior, 1 laser was installed in each of the 2 freestall barns at the Knott Dairy Center at Washington State University, Pullman, Washington, USA. …

Comparative Morphology And Ultrastructure Of Olfactory Epithelia In Plethodontid Salamanders: Effect Of Life History Variation, Emily Gremling
Cal Poly Humboldt theses and projects
Many amphibian species rely on olfaction for locating prey and for social interactions during different life stages. Despite the importance of the olfactory system, research on its structure has been taxonomically limited. The most diverse family of salamanders, the Plethodontidae, has been largely excluded from research efforts to describe olfactory morphology. Although several histological studies have been conducted, no studies have yet looked at morphology at the level of ultrastructure using electron microscopy. The primary goal of my research was to examine olfactory morphology and ultrastructure in plethodontid species with a range of life history strategies, to better understand the …

Transgenerational Effects Of Stress On The Plasma Proteome Of A Marine Mammal, Emily Voelkner
Transgenerational Effects Of Stress On The Plasma Proteome Of A Marine Mammal, Emily Voelkner
University of the Pacific Theses and Dissertations
The physiological stress response enables animals to respond to changes in their environment, and is mediated by the hypothalamic-pituitary-adrenal (HPA) axis in mammals. Increased activation of the HPA axis by repeated stress during critical life stages like reproduction could affect fitness. Information about a stressor can be communicated to offspring via hormone signals prenatally, or postnatally via milk, and affect offspring development and stress reactivity. Experimentally activating the HPA axis by adrenocorticotropic hormone (ACTH) administration results in the synthesis of the major glucocorticoid hormone cortisol, which has well-studied far-reaching effects on growth, metabolism, and immunity. Beyond cortisol levels alone, biomarkers …
Performance And Physiological Impacts Of Branched-Chain Amino Acid And Tryptophan Ratio Variations In Turkey Starter Diets Utilizing Concentrated Corn Proteins, Emily Blair Estanich
Performance And Physiological Impacts Of Branched-Chain Amino Acid And Tryptophan Ratio Variations In Turkey Starter Diets Utilizing Concentrated Corn Proteins, Emily Blair Estanich
Graduate Theses, Dissertations, and Problem Reports (ETD)
In Chapter 2, a study was designed to evaluate the effects of varying dietary branched-chain amino acids (BCAA) ratio in corn and soybean meal-based turkey starter diets. The BCAA leucine, isoleucine, and valine are considered indispensable amino acids needed for energy and stimulation of muscle protein synthesis via the mammalian target of rapamycin (mTOR) pathway. Imbalanced BCAA ratios can lead to antagonism and degradation of limiting BCAA, particularly in diets with excess leucine. Concentrated corn proteins contain high levels of leucine and can alter BCAA requirements; however, crystalline BCAA may be added to correct these ratios. This study aimed to …

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 …

Seasonal reproduction can provide species with fitness advantages by allowing the birth of young to coincide with favorable environmental conditions, particularly in environments with high seasonal and intra-annual variation in these conditions. Seven of the eight species in the bear family (Ursidae) reproduce seasonally in both managed care and the wild; however, data for the eighth species, the sun bear (Helarctos malayanus), is unclear. Sun bears have been observed to reproduce throughout the year in managed care, yet currently there are no clear data of birth timing for wild sun bear cubs. Here we investigate the seasonality of …
Efficacy Of Bacillus-Based Probiotic And Nspase Supplementation On Growth Performance And Gut Health Of Broilers Fed High Level Of Palm Kernel Meals Under High Stocking Density, Nurul Imawati

Palm kernel meal (PKM) is a by-product of the oil palm industry with significant potential in poultry feed, although its high content of anti-nutritional factors limits its utilization. It is hypothesized that dietary supplementation with fiber-degrading enzymes and probiotics may enhance the use of PKM. This study investigated the effects of Bacillus-based probiotics (PRO) and non-starch polysaccharide enzymes (NSPase, mannanase, and xylanase) on broiler performance and gut health when fed a high level of PKM under high stocking density (HSD, Experiment 1) and normal stocking density (NSD, Experiment 2). In Experiment 1, 4,480 mixed-sex Ross308 broilers were allocated to eight …
