Maturation Of Equine Proximal Sesamoid Bones In Thoroughbred Horses, Angela Maria Mangine
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
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
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 …
Science-Based Regulation Of Pharmacological Substances In Competition Horses, Jacob Machin
Science-Based Regulation Of Pharmacological Substances In Competition Horses, Jacob Machin
Theses and Dissertations--Toxicology and Cancer Biology
Current testing methodologies within equine forensic toxicology focus on arbitrary thresholds and zero-tolerance policy. Modern analytical chemistry’s limits of detection are low enough that oftentimes femtogram-per-milliliter amounts of a substance can readily be identified in both blood and urine of a horse. For most pharmacologically relevant compounds, these concentrations have no relevance to pharmacological effect. It is therefore crucial that testing methodologies to determine appropriate thresholds and cut-offs be developed that are driven by biological activity rather than arbitrary limits of detection. This dissertation looks to address this by suggesting a system of calculated Effective Plasma Concentrations by which a …
An Assessment Of The Carrier State And A Novel Marker Of Leptospira And Abortion In Central Kentucky Horses, Gloria Louise Gellin
An Assessment Of The Carrier State And A Novel Marker Of Leptospira And Abortion In Central Kentucky Horses, Gloria Louise Gellin
Theses and Dissertations--Veterinary Science
Leptospirosis is a reemerging zoonotic infection of worldwide importance and affects all mammals. The bacterium is transmitted to animals and humans by urine, fetal membranes and body fluids. Leptospira shedding in the urine contaminates both soil and water, exposing both humans and animals to the bacterium. Leptospirosis in horses can cause abortion and is one of the etiologies of equine recurrent uveitis which can lead to blindness. Equine leptospiral abortion in Central Kentucky is primarily caused by serovar Pomona, with occasional cases attributed to serovar Grippotyphosa. There are a few reports in the literature attributing abortion to serovar Bratislava in …
Predicting Tomorrow: Optimizing The Early Detection Of Disease And Disease Recovery In Dairy Calves Using Precision Technologies, Melissa Cantor
Predicting Tomorrow: Optimizing The Early Detection Of Disease And Disease Recovery In Dairy Calves Using Precision Technologies, Melissa Cantor
Theses and Dissertations--Animal and Food Sciences
The leading causes of morbidity and mortality in preweaned dairy calves are diarrhea and bovine respiratory disease complex (BRD). The delayed detection of these diseases in calves can also delay intervention and disease recovery. The overarching objective of this dissertation was to follow a cohort of calves daily for the first 90 days of life for naturally occurring clinical BRD bouts and diarrheal bouts. The objective answered if feeding behaviors and activity levels were different in at-risk calves during BRD development and BRD recovery from an antimicrobial intervention. Furthermore, the potential of colostrum replacer as a feeding intervention strategy to …
Stress, Burnout, And Well-Being In New Veterinary Graduates: Evaluating A Pilot Online Professional Development Program, Addie Rose Reinhard
Stress, Burnout, And Well-Being In New Veterinary Graduates: Evaluating A Pilot Online Professional Development Program, Addie Rose Reinhard
Theses and Dissertations--Community & Leadership Development
Suicide, stress, and burnout are occurring at high rates among veterinary professionals, and the transition from student to practicing veterinarian has been shown to be a particularly stressful time. The aim of this study was to evaluate an online professional development program for new veterinary graduates incorporating peer social support and training in professional skills important for success in the transition to practice. In this mixed methods study, the program was evaluated qualitatively with focus group data and quantitatively by assessing knowledge gained and levels of stress, burnout, social support, and well-being. Seven new veterinary graduates participated in the program, …
