The Effects Of Pelleted Cannabidiol Supplementation On Heart Rate And Reaction Scores In Horses, Anna L. Draeger, Evan P. Thomas, Kiara A. Jones, Shea Porr Nov 2021

The Effects Of Pelleted Cannabidiol Supplementation On Heart Rate And Reaction Scores In Horses, Anna L. Draeger, Evan P. Thomas, Kiara A. Jones, Shea Porr

Faculty & Staff Research and Creative Activity

The potential use of cannabidiol (CBD) as a nutraceutical to support improved health and welfare has been of increasing interest. In particular, CBD has been shown to decrease anxiety in humans and small animals. While there is little research published on the effects of CBD supplementation in horses, its use is increasing rapidly. The objective of this study was to determine the effect of feeding a pelleted CBD supplement on equine reactivity and heart rate (HR). Seventeen stock-type geldings were divided into control (CON) or treatment (TRT) groups. The TRT group received 100 mg of CBD once daily. Control horses …


Morph- And Sex-Specific Differences In Corticosterone Of The Arizona Tiger Salamander (Ambystoma Mavortium Nebulosum), Megan Zerger Mar 2021

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 Mar 2021

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 …


Impacts Of Digestawell Nrg Supplementation On Post Exercise Muscle Soreness In Unconditioned Horses, A Pilot Study, Jessica K. Suagee-Bedore, Yeting Shen, Shea Porr, Ivan D. Girard, Karen Bennett-Winbrush, Ashley L. Wagner Mar 2021

Impacts Of Digestawell Nrg Supplementation On Post Exercise Muscle Soreness In Unconditioned Horses, A Pilot Study, Jessica K. Suagee-Bedore, Yeting Shen, Shea Porr, Ivan D. Girard, Karen Bennett-Winbrush, Ashley L. Wagner

Exercising horses are commonly plagued by muscle fatigue and soreness, which can result in reduced performance ability. In the present study, ten unconditioned horses were fed 200g per day DigestaWell NRG, a commercial dietary supplement containing Yucca schidigera and Trigonella foenum-graecum, two herbs shown in other species to reduce post-exercise muscle pain and soreness. A control, unsupplemented group contained ten horses of similar age, breed, and gender. Horses completed a 50 minutes, ridden standardized exercise test of moderate intensity immediately prior to (Period1) and after 28 days of supplementation (Period2). Muscle soreness and tightness were evaluated 24 hours prior …


A Survey Of Horse Use And Management In Horse Clubs In China: A Pilot Study, Zhen Li Ph.D., Msc, Shea Porr Phd Jan 2021

A Survey Of Horse Use And Management In Horse Clubs In China: A Pilot Study, Zhen Li Ph.D., Msc, Shea Porr Phd

Steeplechase: An ORCA Student Journal

Rapid development of the Chinese equine industry in the last two decades has resulted in an increased equine population without trained personnel to support industry growth. The purpose of this study was to understand the present profile of horse use in horse clubs in China from the perspective of horse welfare. The survey was distributed to specific personnel in selected Chinese horse clubs, and snowball sampling techniques were used to increase response rates. Of 20 respondents, the oldest club was established in 2002 and the newest in 2018. Fourteen clubs were membership-based, providing services for 40-1000 members and up to …


Pharmacokinetics Of A Single Feeding Of Pelleted Cannabidiol In Horses, Anna L. Draeger, Laura K. Hoffman, Patricia R. Godwin, Amanda J. Davis, Shea A. Porr Jan 2021

Pharmacokinetics Of A Single Feeding Of Pelleted Cannabidiol In Horses, Anna L. Draeger, Laura K. Hoffman, Patricia R. Godwin, Amanda J. Davis, Shea A. Porr

Steeplechase: An ORCA Student Journal

Claims about cannabidiol (CBD) supplementation improving health and behavior are extensive, but research is lacking. Some studies have shown decreased anxiety behavior in rats, and increased activity in osteoarthritic dogs supplemented with CBD, but even less research exists on horses. This study monitored pharmacokinetics and short-term safety for 3 CBD dosages. Eighteen Quarter Horse geldings were randomly assigned to 3 treatment groups: 50 mg (TXT1), 100 mg (TXT2), and 250 mg (TXT3). Dosage was derived from manufacturer recommendations and existing literature on other species. Horses were fed a single dose of CBD pellets. Blood was collected pre- and post-treatment at …


Dirofilaria Immitis Prevalence In Canis Latrans In Kentucky, Melanie Ann Brandon Jan 2021

Dirofilaria Immitis Prevalence In Canis Latrans In Kentucky, Melanie Ann Brandon

Murray State Theses and Dissertations

Dirofilaria immitis (canine heartworm) was found in forty-two (42) of the two hundred seventy-five (275) Canis latrans (coyote) necropsied in the state of Kentucky from November 27, 2019 through March 3, 2021. Thirty-five (35) of the positive cases were from western Kentucky region with the other seven spread across the state. With this group of coyotes, one hundred fifty-eight (158) were male and the other one hundred six-teen (116) were female. The estimated age ranged from a pup to senior dogs. A little over forty percent of the dogs were obtained through coyote/predator tournaments; the remaining were acquired from pest …
