Equine Rescue Success In The United States: A Statistical Analysis, Carly J. Cave

Honors Theses and Capstones

The high inflation that has characterized the post-pandemic period in the United States has increased the costs of horse ownership for private owners and equine rescue organizations, which are facing critical pressures. Over 200,000 equines are at risk for neglect or slaughter in the United States each year, which far exceeds the capacity to house these equines at rescue organizations. While demand on these organizations is high, their ability to afford appropriate resources for their care is insufficient. This study examined geographical and economic factors that impact equine rescues’ success in taking in at-risk equines and adopting them to forever …

Precision Application Of Water To Equine Racing Surfaces, Sydney Rae Cannon

Theses and Dissertations--Biosystems and Agricultural Engineering

As the horseracing industry has come under more scrutiny as of late, horse and rider safety has become a priority. The best was to keep a rider safe is to keep them on their horse, and the best way to do that is to keep the horse upright. This all comes down to consistency both between tracks and across a single track. The most important method of managing track consistency is through moisture content. This study examined how track design can impact moisture application, how moisture content can impact the surface material, and what design elements can be implemented to …

Regenerative Medicine For Tendon/Ligament Injuries: De Novo Equine Tendon/Ligament Neotissue Generation And Application, Takashi Taguchi

LSU Doctoral Dissertations

Tendon and ligament injuries are debilitating conditions across species. Poor regenerative capacities of these tissues limit restoration of original functions. The first study evaluated the effect of cellular administration on tendon/ligament injuries in horses using meta-analysis. The cellular administration was effective in restoring ultrasonographic echogenicity and increasing vascularity during early phase of healing. Additionally, it improved microstructural organization of healed tissue in terms of cellularity and fiber alignment. However, the study did not support its use for increasing rate of return to performance, expression/deposition of tendon-specific genes/proteins, or mechanical properties.

The findings led to the second study that engineered implantable …

Effects Of High-Speed Training On Messenger Rna Expression In Two-Year-Old Thoroughbred Racehorses, Mackenzie Grace Johnson

Theses and Dissertations--Veterinary Science

Accumulating high-speed exercise has been identified as a significant risk factor for catastrophic injuries in racing Thoroughbreds. Injuries, regardless of severity, are a main cause of withdrawal from the racing industry, raising animal welfare concerns and resulting in significant economic losses. While most of the current literature focuses on catastrophic injuries incurred during racing rather than training, the present study aims to help fill this gap as well as discuss the associated risk factors. The evaluation of messenger RNA (mRNA) expression changes provides an efficient and straightforward approach to identifying horses at risk for catastrophic injury. While alternative injury risk …

Immunohistochemical Localization Of Kisspeptin And Its Receptor In The Equine Ovary, Bryce M. Gilbert

LSU Master's Theses

Kisspeptin is recognized for its role as the gatekeeper of reproduction in most mammalian species. However, its role in regulation of reproduction at the ovarian level is poorly understood in the horse. In this study, ovaries from follicular phase, luteal phase, anestrous period, and mares treated with ECP-sulpiride were subjected to immunohistochemistry to characterize kisspeptin-10 (Kp10) and its receptor (Kiss1r) protein expression throughout each reproductive stage and follicle type. Kisspeptin and receptor staining was detected in all follicle types (primordial, preantral, and antral) throughout all reproductive stages, as well as oocytes, corpora lutea, and ovulation fossa. The pattern of Kp10 …

Intra-Articular Buprenorphine In Horses, Gabriel Castro-Cuellar Dr

LSU Master's Theses

Opioid drugs have the potential of provide local analgesia in inflamed joints. To date, morphine is the only opioid that has been tested for intra-articular (IA) administration in horses. Having an alternative drug, other than morphine, could widen the therapeutic options, particularly in cases of drug shortages or inaccessibility to specific drugs. The work presented in this dissertation reports the cytotoxic effects of buprenorphine on cultured equine chondrocytes, and the pharmacokinetic, pharmacodynamic and analgesic effects, of IA administered buprenorphine in horses with experimentally induced synovitis.

To evaluate the potential cytotoxic effects on equine cartilage, chondrocytes were obtained from normal equine …

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 …

Mechanical Engineering

This document outlines our senior design project for the Cal Poly Mechanical Engineering Department on behalf of Jack’s Helping Hand. As a team of two Mechanical Engineering students, we developed a structure that can support a rider and can move in three degrees of freedom to model the gait patterns of a horse. This senior project will be continued by another group that will focus on electronics and implement the motors that will induce motion on the structure that our team has built. We collected baseline data by attaching an iPhone to a horse and used that motion to compare …

Development And Validation Of A Basic Ground Skills Assessment For Equine-Assisted Services, Sarah J. Andersen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The equine-assisted services program at Utah State University produced and validated an assessment process used to test equines for suitability for equine-assisted services. Equine-assisted services incorporate the interaction of humans who face mental, physical, emotional, and/or social challenges and equines for therapeutic purposes. Recreational, physical, mental, social, and/or emotional goals are met through various equine-assisted services such as therapies, equine-assisted learning, and horsemanship.

Due to the potential for human injury while interacting with equines, it is important to ensure equines are assessed for safe behavior prior to participation in equine-assisted services. This is why our group developed and tested the …

All The King’S Horses: Stable Administration In New Kingdom Egypt, Tessa Genevieve David Litecky

Theses and Dissertations

Horses were an important part of Egyptian society during the New Kingdom as tools of warfare, status symbols of the elite, and an emblem of the power of kingship. However, little is known about how these animals were trained and cared for, or who was working in horse stables and their roles. There are no texts or images that explicitly explain methods of horse management. Therefore, this topic has been generally overlooked in the literature. This thesis combines two threads of evidence to create a more complete picture of the organization, purpose, and function of horse stables and the treatment …

Maturation Of Equine Proximal Sesamoid Bones In Thoroughbred Horses, Angela Maria Mangine

Theses and Dissertations--Veterinary Science

Proximal sesamoid bone (PSB) injuries account for approximately 50% of all fatal catastrophic musculoskeletal injuries in Thoroughbred racehorses. In addition, PSB fractures are not uncommon in Thoroughbred foals and yearlings as a result of energetic or intense free exercise. The ability to interpret some PSB pathology assessments, however, is more difficult given the limited information published on the normal development and maturation of these paired sesamoid bones. In addition, the level of normal variation in PSB morphological and structural parameters within the Thoroughbred population as a function of age, body size, gender, and inter-animal variation are not well documented, complicating …

Muscle Mass And Immune Function In The Senior Horse, Alisa Christina Herbst

Theses and Dissertations--Veterinary Science

Senior horses (≥ 15 years) represent up to one-third of the global equine population, and the proportion of old horses (≥ 20 years) in the U.S. has been steadily increasing. Aging is associated with a loss of skeletal muscle mass in horses, and while age-related muscle loss is comparingly well characterized in humans, little is currently known concerning underlying mechanisms, adverse outcomes, or the prevalence of low muscle mass in senior horses. One factor proposed to play a role in the development of age-related muscle atrophy in humans is inflamm-aging, a low-grade inflammation that affects elderly people and that has …

Structural Adaptation Of Equine Proximal Sesamoid Bones To High-Speed Exercise, Kathryn Mary Babiarz

Theses and Dissertations--Veterinary Science

Proximal sesamoid bone (PSB) fractures are one of the most commonly reported catastrophic musculoskeletal injuries (CMI) in Thoroughbred racing. Despite the seriousness of these injuries, an understanding of the structural changes that occur normally within PSBs in response to the biomechanical forces of high-speed exercise and how they relate to pathological events leading to fracture remain limited. To address this critical knowledge gap, PSBs from Thoroughbred horses were analyzed with both computed tomography (CT) and microcomputed tomography (µCT) to assess their morphological and structural parameters. Comparisons were made using samples from the left and right forelimbs of Thoroughbreds of both …

Novel Information About The Kinetic Effects Of Equine Shoe Modifications And Kinematic Effects Of Human Digital Devices For Improved Performance In Both Species, Pengju Wang

LSU Master's Theses

Equine shoes are frequently modified to enhance traction for horses that travel on paved surfaces for work, pleasure, or entertainment. Little is known about other common shoe modifications used to enhance traction like calks, tungsten carbide granules, or plastic composition. This information is vital to shoe design to protect the safety and welfare of all service, working, and leisure horses. The objective of the first part of this thesis was to quantify the effect of shoes with and without traction adaptions on kinetic measures in non-lame, light breed horses at a trot. Kinetic data was collected with a force platform …

Ritualistic Equestrianism: Status, Identity, And Symbolism In Tudor Coronation Ceremonies, Keri Blair

Electronic Theses and Dissertations

The crowning of a King or Queen of England is and remains an essential part of English tradition. For centuries, British subjects have flocked to the city streets to catch a glimpse of their next monarch. For the Tudors, the spectacle of pageantry was often an ostentatious display of wealth and grandeur. Using horses as an historical lens, this study will examine four different components of equestrianism in Tudor coronation ceremonies: The King’s Champion, the Gilded Spurs, the Master of the Horse, and the Horse of Honor. Despite significant political, religious, and cultural changes that occurred during the Tudor era, …

A Case Study Comparing The Life Skills Development And Knowledge In Youth Participants Of Horseless And Traditional Horse Programs In Utah, Haley M. Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Traditional horse 4-H programs develop life skills and knowledge in youth. Horseless horse programs lack evaluation for the same benefits. This study evaluated and compared four horseless and seven traditional horse participants from Washington County 4-H in Utah for gains in horse knowledge and development of 10 life skills that are commonly found in 4-H curriculum today: leadership, teamwork, self-responsibility, personal safety, problem solving, decision making, critical thinking, goal setting, communication, and concern for others.

The researcher conducted interviews to learn about life skill experiences of the horse program participants and discover what barriers prevented horseless youth from participating in …

The Effect Of Hay Net Use On Cribbing Horses, Lauren Wesolowski

Undergraduate Honors Thesis Projects

Cribbing is a stereotypic behavior observed in horses, wherein the animal grasps a solid object with its front incisors and contracts its neck muscles to suck in air through its mouth, resulting in an audible grunt. Stereotypic behaviors such as cribbing are thought to be done in response to stress or insufficient stimulus in an animal’s living environment. Slow feeding hay nets can increase the amount of time horses spend eating daily hay rations. This research aims to use slow feeding hay nets to create a feeding process that is closer to natural grazing behavior and provide more stimulation for …

Comparative Chondrogenesis Of Interzone And Anlagen Cells In Equine Skeletal Development, Chanhee Mok

Theses and Dissertations--Veterinary Science

At the presumptive sites of future synovial joints during mammalian skeletogenesis, articular cartilage develops from interzone located between the cartilaginous anlagen of bones. Thus, two types of cartilaginous tissues differentiate in close proximity. While anlagen cartilage is transient, progressing through endochondral ossification to form bones, articular cartilage is stable and functions throughout life to facilitate both low friction movement and load distribution. Despite important life-long functional properties, articular cartilage has a very limited intrinsic ability to repair structural defects. On the other hand, structural lesions in bones generally heal well by forming a cartilaginous callus and recapitulating endochondral ossification to …

Donor Age Effects On The Proliferative And Chondrogenic/Osteogenic Differentiation Performance Of Equine Bone Marrow- And Adipose Tissue Derived Mesenchymal Stem Cells In Culture, Jasmin Bagge

Theses and Dissertations--Veterinary Science

Orthopedic injuries are a major cause of lameness and morbidity in horses. Bone marrow (BM)- and adipose tissue (AT) derived mesenchymal stem cells (MSCs) have shown potential to facilitate the repair of orthopedic injuries and are being used increasingly in veterinary clinics. Presently, the use of MSCs as a therapy for equine patients is most commonly applied as autologous transplants, using BM- and AT-MSCs harvested from the patient shortly after the time of injury. Cell-based therapies are therefore delayed to enable primary cell numbers to be expanded in culture. Of concern, however, are human and rodent studies that have shown …

Effects Of Adrenergic Or A Combination Of Adrenergic And Opioid Drugs On Assessments Of Insulin Sensitivity In Mares, Lauren Kerrigan

LSU Master's Theses

Excitement is a problem when conducting endocrine tests on fractious horses. Epinephrine (EPI), for example, was shown to obliterate the insulin-induced decrease in blood glucose concentrations. Sedation may be a solution; however, perturbation of results may preclude useful information. The objectives of the four experiments presented herein were 1) to determine the effects of EPI on insulin response to glucose infusion (IR2G), 2) to assess the effects of the α-adrenergic sedative, detomidine (DET), alone or in combination with the opioid agonist, butorphanol (BUT), on IR2G and glucose response to insulin (GR2I), and 3) to assess the effects of BUT alone …

Horses, Culture, And Trade: The Impact Of The Horse On Southeastern Native Nations, 1650-1830, Jacob Featherling

Master's Theses

A small portion of the regional literature details the impact of horses on Southeastern Native nations and focuses on a few of the larger groups, particularly the Choctaw, from the mid-eighteenth to the nineteenth century. This thesis intends to increase the scope to analyze the entire Southeastern region, as well as multiple Native nations in the area. The thesis argues that Southeastern Natives slowly adopted horses into their economies and cultures over a longer period of time than previously believed, allowing them to increase their use of horses easily to meet market demands. Instead of southeastern nations rapidly adapting their …

Mechanisms Of Type-I Ifn Inhibition: Equine Herpesvirus-1 Escape From The Antiviral Effect Of Type-1 Interferon Response In Host Cell, Fatai S. Oladunni

Theses and Dissertations--Veterinary Science

Equine herpesvirus-1 (EHV-1) is one of the most important and prevalent viral pathogens of horses causing a major threat to the equine industry throughout most of the world. EHV-1 primarily causes respiratory disease but viral spread to distant organs enables the development of more severe sequelae; abortion and neurologic disease. In order to produce disease, EHV-1 has to overcome the innate barrier of the type-I interferon (IFN) system in host cells. However, the underlying mechanisms employed by EHV-1 to circumvent the type-I IFN response in host cells are not well understood. In this project study, using molecular techniques, we explored …

Effects Of A Systemic High Urea Concentration On The Endometrial And Embryonic Transcriptomes Of The Mare, Yatta Linhares Boakari

Theses and Dissertations--Veterinary Science

Pregnancy loss remains a major source of economic cost to the equine industry. Frequently, the exact causes of pregnancy loss remain unknown. It has been shown, in other species, that increased dietary protein leading to elevated blood urea nitrogen concentrations (BUN) can be a factor in decreased survival of the early embryo. Our studies provided novel information regarding the effects of elevated BUN on endometrium and embryos from mares as well as insights on changes in their gene expression. Our first objective was to develop an experimental model to elevate BUN during diestrus using intravenous urea infusion. We analyzed the …

A Two-Fold Study Of Equine Weaning Practices And Behaviours Displayed Following Mare Removal, Catherine Mcmeeking

School of Biological and Marine Sciences Theses

The behavioural effects on the foal and dam during weaning in horses are well documented and it is commonly agreed that both are likely to suffer from stress at this time. Many different weaning methods are employed worldwide, with no indication of the least stress inducing. This study has two aims. First, to document frequency of weaning method, type of breeder, foal age at the time of mare removal and reason for use of weaning method. Second, to compare behaviours following abrupt and gradual weaning methods. The first aim was addressed by a questionnaire distributed globally via social media and …

Detailed Geologic Mapping Of The Parksville 7.5-Minute Quadrangle And The Kinematics Of Emplacement Of Large Horses Along The Great Smoky Fault, Southeastern Tennessee, Trenton Joel Walker

Masters Theses

The Great Smoky fault is a major Alleghanian thrust fault in the southern Appalachians that separates the highly deformed and metamorphosed Blue Ridge to the east from the less deformed and unmetamorphosed Valley and Ridge to the west. The trace of the frontal Blue Ridge, as defined by the Great Smoky fault, displays a change in strike from ~010° to ~045° in or near the Parksville 7.5-minute quadrangle in southeastern Tennessee. This change in strike defines the southern arc of the Tennessee salient, which is a convex-to-the-foreland curve in the structural front of the southern Appalachians. Along the Great Smoky …

The Effect Of Forage Quality On Voluntary Hay Intake, Serum Glucose And Insulin, Muscle Glycogen, Whole Blood Lactate, Heart Rate, And Respiratory Parameters Of Exercised Horses, Caitlin M. Chase

Theses and Dissertations

Six mares and six geldings were used to determine the effect of forage quality on muscle glycogen utilization by exercised horses. Horses were fed 1.5% BW/d of high quality (65.6% NDF; 41.1% ADF) or low quality (74.6% NDF; 51.2% ADF) hay and a concentrate resulting in three diets: high quality hay and concentrate balanced to meet energy requirements (HQ); low quality hay and concentrate balanced to meet energy requirements; and low quality hay with the same amount of concentrate as the HQ diet. The effect of hay quality on serum insulin, serum glucose, whole blood lactate, and respiratory parameters were …

The Physical Therapeutic Benefits Of Hippotherapy On Children With Physical Disabilities, Heather Brand

Culminating Projects in Special Education

Hippotherapy is a great choice of treatment for children with physical disabilities. It can improve gross motor function, balance, spasticity, posture, and gait, as reviewed in this paper. It can also have benefits for many other areas in the child’s life, physically or mentally. This form of therapy may be so effective because children often are able to connect to animals and it is fun to ride a horse; they may be more motivated in doing the therapy activities than with a traditional form of treatment.
