Cannabidiol In The Horse: Pharmacokinetics And Effects Of A Pelleted Supplement On Reactivity And Movement, Anna L. Draeger Jan 2020

Cannabidiol In The Horse: Pharmacokinetics And Effects Of A Pelleted Supplement On Reactivity And Movement, Anna L. Draeger

Murray State Theses and Dissertations

A multitude of claims exist regarding therapeutic benefits of cannabidiol (CBD) in human and animal medicine. Though supportive evidence of CBD as a nutraceutical option exists, lack of regulation means that product safety, consistency, and efficacy cannot be guaranteed. Trials for specific conditions and species are needed. The objective of this study was to evaluate CBD safety and use effects on reactivity and movement in the horse. Project 1 examined the bioavailability of a single 50 mg dose of an oil and pelleted CBD product. One of 2 Quarter Horse geldings received the oil product. The second received the pelleted …

Effects Of Roundup On Behavior, Growth, And Mortality Of Larval Blue Dashers, Pachydiplax Longipennis, Kayleen K. Parker, Claire A. Fuller

Murray State Theses and Dissertations

The objective of this study was to determine if Roundup (active ingredient: Glyphosate) causes negative effects on behavior, growth, and mortality of larval Pachydiplax longipennis. Larvae were captured from rainwater-filled mesocosms at Hancock Biological Station in Murray, KY. Larvae were exposed to one of four concentrations of Roundup (0mg/L, 2.5mg/L, 5mg/L, or 10mg/L). Daphnia consumption, seek refuge, and anti-predator trials were conducted at 7 and 14 days post-exposure. Growth and survival trials were carried out for eight weeks using different larvae. There were no significant differences among treatments for whether or not larvae ate offered Daphnia for Day 7 …

The Effects Of Reward-Based Training On The Behavioral Assessment Of The Domestic Dog, Shelby Vandergraff, Shelby K. Vandergraff

Murray State Theses and Dissertations

Contrary to popular belief, pet overpopulation is caused more by owners failing to keep their dog than with accidental or intentional breeding (Moulton et al., 1991). Factors related to relinquishment have been researched, and concluded that behavioral problems are the most reoccurring reasons observed (Bailey, 1992; Miller at al., 1996; Patronek et al., 1996; Serpell, 1966; Salman et al., 1998, 2000; Scarlett et al, 1999; New et al., 2000; Shore et al., 2003, 2005; Mondelli 2004, Blackwell et al., 2008). When animals are relinquished to the shelter, the likelihood of the animal being euthanized increases. The purpose of this research …
