Sample Storage Method And Collection Time Effects On Horse Hair Cortisol Concentrations, Grace Robertson

Scholars Week

Serum cortisol concentration is the gold standard for evaluating stress in horses. However, it can be affected by circadian rhythms, environmental factors, and other excitatory events. Hair cortisol is less subject to these variables and is less invasive to collect, but there is a lack of published information on hair cortisol concentrations in horses. The objectives of this study were to examine 1) the impact of sample storage (Room temperature vs. Frozen) and 2) the effect of collection date (spring vs. fall), on cortisol concentration in equine hair. It was hypothesized that Frozen samples would yield higher concentrations than Room …

Goat Tying Styles Impact On Performance Consistency With Rodeo Competitors In The National Intercollegiate Rodeo Association Ozark Region, Marie Baxley, C.A. Shea Porr, Thomas Powell

Honors College Theses

Goat tying is a rodeo event involving dismounting a horse, and flanking and tying three legs of a goat. Flanking is defined as picking a goat up and setting it on the ground on its side. Flank/gather (FG) is a style where riders scoop the legs with the right hand and then place them in the left. Catch the flank (CF), stuffing (ST), and funneling (FN) are other methods that involve the goats’ legs landing together so the right hand is not needed for gathering. The objectives of this study were to determine 1) if flanking method affects performance, and …

Equine Hair Cortisol Concentration And The Effects Of Season, Storage Method, And Personality Traits, Savannah M. Rivers, Grace A. Robertson, Thomas Powell, Lydia O'Sullivan, Shea Porr

Murray State Theses and Dissertations

Stress exists everywhere, for survival, adaptation is necessary. These adaptations directly reflected the stresses the animal experienced and demonstrated the ability to cope. An animal that could not cope could not survive. Stressful experiences resulted in behavior patterns for each animal. Consistent behavior can be defined as personality [1]; therefore, stress could directly influence personality by changing behavior.

Stress research helped analyze and identify animal personality traits, especially horses. Human-horse pairings partially relied on personality traits and, when considered, often led to improvements in welfare [2]. There are various tools to assess personality, one being Equine Personality Assessment [3]. The …

Assessing The Behavioral And Health Effects Of Turtle Racing On Eastern Box Turtles (Terrapene Carolina Carolina), Michelle Weaver

Murray State Theses and Dissertations

To make informed management decisions regarding box turtles (Terrapene spp.) and other turtle species, one must understand what influences them at multiple levels of biological organization. Common influences include the pet trade, urbanization, habitat degradation, and disease. One factor that has not been studied but could influence turtles at multiple levels of biological organization is turtle racing. It is common practice to use wild caught turtles at these events because there is a lack of regulation and enforcement. My study focused on evaluating the effects of turtle racing on eastern box turtles (Terrapene carolina carolina; hereafter EBTs) …

Pharmacokinetics Of Cbd Supplementation In Horses: Single Dose Vs. Long-Term Feeding, Madilyn Adamchik

Honors College Theses

Research about supplemental feeding of cannabidiol (CBD) to horses is still in its early stages, but many horse owners are feeding CBD supplements for supposed benefits, including behavior and pain management. Cannabinoids work through the endocannabinoid system to modulate nervous and hormonal actions in the body, working to maintain a healthy homeostatic balance. Safety and efficacy have been tested for dosages of up to 500 mg of CBD per day for horses, but further research about the pharmacokinetics based on dosage amount and form of CBD are still needed. The objectives of this study were to evaluate the pharmacokinetics of …

Adaptive Plasticity Of Coloration In Response To Environmental Change, Karissa Coffield

Scholars Week

When rapid environmental changes occur, different selective forces can create phenotypic trade-offs in which a trait can provide fitness benefits or costs under different environmental conditions. Amphibians are particularly vulnerable to environmental change, and previous research has revealed that some species will plastically respond to variation in temperature and ultra-violet radiation (UVR) by altering their coloration. Divergent selection on coloration may change with elevation and climate induced shifts in temperature because high temperatures are likely to result in lighter color morphs but as elevation increases, UVR exposure increases leading to the prediction that darker color morphs will be more common. …

Seroprevalence And Titer Concentration Testing For Leptospirosis In Equine, Ashley Himmelsbaugh

Posters-at-the-Capitol

The most common best management practice used to combat diseases in horses is vaccination, which can decrease the incidence or severity of illness. However, the duration of immunity will vary for each vaccination and must be considered for revaccination purposes. Titer concentration, which evaluates antibodies in the blood, may be a helpful way of determining how long an animal has immunity to a disease. Leptospirosis, a zoonotic, bacterial disease, can result in uveitis, potentially leading to blindness, and abortion in mares. One serovar, Leptospirosis pomona (L. pomona), is associated with most cases of clinical disease in horses in North America. …

Pharmacokinetics Of Cbd Supplementation In Horses: Single Dose Vs. Long-Term Feeding, Madilyn Adamchik

Posters-at-the-Capitol

Research about supplemental feeding of cannabidiol (CBD) to horses is still in its early stages, but owners are feeding CBD to relieve pain and calm behavioral issues. Cannabinoids work through the endocannabinoid system to modulate nervous and hormonal actions in the body. The objectives of this study were to evaluate the pharmacokinetics of single dose versus long-term feeding of a pelleted CBD supplement. In Project 1, eighteen Quarter Horse geldings were given a single dose of 50 mg (n=6), 100 mg (n=6), or 250 mg (n=6) of pelleted CBD.

Fragile Foal Syndrome: Its Past, Present, And Future, Alena Martin, Alena M. Martin

Honors College Theses

Though Fragile Foal Syndrome (FFS) has been around for some time, the public interest in FFS is recent. The hype spread rapidly from a public media announcement that a stallion at a prominent North American stud farm was a carrier (Brooks, 2021). As with most genetic mutations, FFS likely arose due to the increased inbreeding that results from human selection (Orlando & Librado, 2019). Fragile Foal Syndrome affects the enzyme responsible for developing the connective tissues. Two recent case studies highlighted the devastating effect of FFS on every part of the equine body (Metzger, et al., 2020; Grillos, 2021). So …

Effects Of Covid-19 Mandates On Student Engagement And Management Of Collegiate Equestrian Teams, Travis Fortune

Murray State Theses and Dissertations

Events like a global pandemic can negatively impact how organizations and groups function. From a collegiate perspective, this could include limiting or eliminating participation in co-curricular activities that have positive impacts on student experiences. Students use these events to make new friends, socialize and generate a sense of belonging, and gain interactions outside the classroom. In March 2020, a number of mandated restrictions were put into place in the United States in response to COVID-19, and collegiate equestrian teams' ability to practice and show were negatively impacted. Even though some restrictions were beginning to ease as of Fall 2021, many …

Morph- And Sex-Specific Differences In Corticosterone Of The Arizona Tiger Salamander (Ambystoma Mavortium Nebulosum), Megan Zerger

Scholars Week

Life history morph, sex, and body condition are traits that may influence stress within salamander populations because of differences in physiology and environmental conditions. Given widespread declines and the effects chronic stress can have on amphibian health, it is important to understand within-population drivers of stress and how population level variation may influence population viability. Thus, the objective of our study was to assess how corticosterone varies within the Arizona tiger salamander (Ambystoma mavortium nebulosum) population at the Mexican Cut Nature Preserve. We used a non-invasive skin swabbing method to collect baseline and elevated corticosterone from paedomorph (aquatic …

Understanding Relationships Between Stress, Snake Fungal Disease, And Parasitism In Wild Cottonmouth Snake Populations, Emma Fehlker Campbell

Scholars Week

Chronically raised stress levels are known to correlate with decreased immune function in vertebrates, possible leading to increased susceptibility to infections including parasitism and Snake Fungal Disease (SFD). Helminth endoparasites and Hemoparasites are frequently found in wild populations but little is known about their physiological effects. Additionally, parasite infection may have interactive effects with diseases including SFD. To our knowledge few studies have assessed potential interactions between SFD and parasites in snakes. Thus, the objective of our study is to assess the individual and interactive effects of Helminth endoparasites, hemoparasites, and snake fungal disease on cottonmouth physiological stress. We are …
