Equine Kinesiology Tape Application To Equine Hock Joints: Impact On Lameness And Movement Evaluation, Kiara Jones
Honors College Theses
Discomfort in the hocks of horses can cause lameness, resulting in poor performance. Diagnosis by veterinarians typically includes evaluating movement or use of ultrasound or radiography to evaluate tendons, ligaments, or bones. Treatment methods and times vary depending on diagnosis, but often include joint injections, medications, and stall rest. Treatments can be costly both financially and regarding time off from practice or competition. Alternative practices such as using equine kinesiology tape to support joints may improve comfort and movement for lower cost. The objective of this project was to evaluate the ease of use and effects of equine kinesiology tape …
Seroprevalence And Titer Concentration Testing For Leptospirosis In Equine, Ashley Himmelsbaugh
Seroprevalence And Titer Concentration Testing For Leptospirosis In Equine, Ashley Himmelsbaugh
Honors College Theses
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. …

Graduate Theses and Dissertations
The objective of this thesis was to determine the anticoccidial profile of Eimeria spp. derived from wild turkeys. These drug-sensitive Eimeria spp. have potential to be used as vaccine candidates to control coccidiosis in commercial turkeys. Chapter two consists of a brief literature review focused on coccidiosis in turkeys. Chapter three addresses the methodologies utilized to isolate, recover, and speciate Eimeria recovered from wild turkey feces in the eastern two-thirds of the United States. From this, we successfully obtained single oocyst-derived stocks for E. meleagrimitis, E. dispersa, E. meleagridis, E. gallopavonis, and E. adenoeides. Chapter four describes the experiment conducted …

Gabapentin, 1-(Aminomethyl)cyclohexaneacetic acid, MW 171.240, is a frequently prescribed high dose human medication that is also used recreationally. Gabapentin is orally absorbed; the dose can be 3,000 mg/day and it is excreted essentially unchanged in urine. Gabapentin is stable in the environment and routinely detected in urban wastewater. Gabapentin randomly transfers from humans to racing horses and is at times detected at pharmacologically ineffective / trace level concentrations in equine plasma and urine. In Ohio racing between January 2019 and July 2020,18 Gabapentin identifications, all less than 2 ng/ml in plasma, were reported. These identifications were ongoing because the horsemen …

Based on structural similarities and equine administration experiments, Barbarin, 5-phenyl-2-oxazolidinethione from Brassicaceae plants, is a possible source of equine urinary identifications of aminorex, (R,S)-5-phenyl-4,5-dihydro-1,3-oxazol-2-amine, an amphetamine-related US Drug Enforcement Administration (DEA) controlled substance considered illegal in sport horses. We now report the synthesis and certification of d5-barbarin to facilitate research on the relationship between plant barbarin and such aminorex identifications. D5-barbarin synthesis commenced with production of d5-2-oxo-2-phenylacetaldehyde oxime (d5-oxime) from d5-acetophenone via butylnitrite in an ethoxide/ethanol solution. This d5-oxime was then reduced with lithium aluminum …
Ex Vivo Biomechanical Comparison Of A Novel Compression Screw Fastener And Traditional Ao Cortical Bone Screw For Fixation Of A Simulated Slab Fracture In The Equine Third Carpal Bone, Allison Salinger
Theses and Dissertations
Frontal plane slab fractures account for the majority of third carpal bone (C3) fractures in performance horses. Treatment is stabilization with an AO cortical screw. Complications are fragment splitting, fragment spinning, and irritation of dorsal soft tissue structures. A novel, headless, cannulated screw with interlocking threads (the Headless Compression Screw Fastener, HCSF) has been developed to resist multidirectional forces. Simulated C3 slab fractures were created in nine paired equine carpi. HCSF or AO cortical screws were loaded in shear to failure. Stiffness, maximum load to failure, and yield load was assessed in linear mixed models. No significant difference was detected …

Zilpaterol is a β2-adrenergic agonist medication approved in certain countries as a cattle feed additive to improve carcass quality. Trace amounts of Zilpaterol can transfer to horse feed, yielding equine urinary “identifications” of Zilpaterol. These “identifications” occur because Zilpaterol is highly bioavailable in horses, resistant to biotransformation and excreted as unchanged Zilpaterol in urine, where it has a 5 day or so terminal half-life.
In horses, urinary steady-state concentrations are reached 25 days (5 half-lives) after exposure to contaminated feed. Zilpaterol readily presents in horse urine, yielding clusters of feed related Zilpaterol identifications in racehorses. The first cluster, April …

Faculty Publications and Other Works -- Large Animal Clinical Sciences
Failure of passive transfer is a management concern for all ruminant species, but is not well described in the literature for camel calves. This case series presents four camel calves (Camelus dromedarius and Camelus bactrianus) referred to a North American veterinary teaching hospital for diagnosis and management of failure of passive transfer. Diagnostics utilized included hematology, serum biochemistry, and immunologic methods as described for crias. Management included antimicrobial, anti-inflammatory, and plasma transfusion therapies. Three of the four calves survived to discharge, and common diagnostic practices such as evaluation of total solids, total protein, immunoglobulin G, and sodium sulfite appear to …
Intra-Articular Buprenorphine In Horses, Gabriel Castro-Cuellar Dr
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 …
Miniature Companion Pig Sedation And Anesthesia, Joseph Smith, Reza Seddighi
Miniature Companion Pig Sedation And Anesthesia, Joseph Smith, Reza Seddighi
Faculty Publications and Other Works -- Large Animal Clinical Sciences
- Miniature companion pigs (MCP) are increasing in popularity, and as such, there is an increased need for veterinarians trained in sedation and anesthesia for the species.
- MCPs have several species-specific qualities that can complicate injectable drug administration and create challenges for inhalational anesthesia (eg, with endotracheal intubation).
- General anesthetic complications, such as hypothermia and hypotension, are commonly described in miniature companion pigs, so monitoring of vital parameters during anesthetic procedures and recovery is crucial.

Livestock Performance In Response To High Intensity Rotational Grazing System, Austin Kennedy
Livestock Performance In Response To High Intensity Rotational Grazing System, Austin Kennedy
Honors Theses
The production of livestock is composed of a variety of factors all effecting the outcome. For grazing livestock, a key factor in production is the grazing management system. Two of the most common grazing management systems are continuous grazing and rotational grazing. There has been evidence found proving benefits of rotational grazing in regard to vegetation productivity, and prevention and restoration of degraded rangeland. However, there is a lack of clear evidence on the relationship between grazing system and production metrics of livestock. Understanding this relationship can provide the necessary information for livestock producers in order to increase their production …

BACKGROUND: Horses are host to a plethora of parasites. Knowledge of the seasonality of parasite egg shedding and transmission is important for constructing parasite control programs. However, studies describing these patterns are sparse, and have largely been conducted only in the United Kingdom. This study evaluated strongylid egg shedding patterns and transmission dynamics of Strongylus vulgaris in naturally infected and untreated mares and foals through one calendar year in Kentucky, USA. The study also investigated the existence of a peri-parturient rise (PPR) in strongylid egg counts in foaling mares and collected information about Strongyloides westeri and Parascaris spp. in the …

Dehydration And Mortality Of Feral Horses And Burros: A Systematic Review Of Reported Deaths, John Derek Scasta, Eric Thacker, Jacob D. Hennig, Karl Hoopes
Human–Wildlife Interactions
Water is a requirement for all organisms, including equids. Dehydration-caused mortality of feral horses (Equus ferus caballus) is often cited as a cause of concern and as justification for management of feral horses, yet a paucity of information exists on the matter. We conducted a systematic review from September 1, 2020 through January 15, 2021 of available news reports of feral horse and burro (E. asinus) dehydration mortalities and public interventions to save horses using a public search engine with a priori defined search term combinations and additional snowball sampling. We found 15 uniquely reported mortality …

The Effect Of Intra-Articular Corticosteroids On The Systemic Messenger Rna Response In An Equine Experimental Inflammation Model, Emma Elaine Partridge
Theses and Dissertations--Veterinary Science
Intra-articular (IA) corticosteroids are regularly used in equine athletes for the control of joint inflammation. The goal of this study was to utilize an acute synovitis inflammation model to determine the residual effects of IA betamethasone and triamcinolone acetonide on various inflammatory parameters and lameness.
Five mixed-breed, 2-year-old horses were randomly allocated to an IA treatment of the radiocarpal joint with 9 mg of either betamethasone or triamcinolone acetonide. Two weeks following treatment, horses were injected with 1μg of lipopolysaccharide (LPS) diluted in 1 mL of 0.9% sterile saline. Following LPS injection, horses were crossed-over and both sets of injections …
