Pilot Testing A Survey To Evaluate Horse Owner And Trainer Perceptions Of The Importance And Ideality Of Equine Hoof Balance, Katherine Gilmore

Animal Science Undergraduate Honors Theses

Balance plays an integral role in the healthy equine hoof, yet there is a significant deficiency of research investigating horse owner and trainer knowledge of hoof balance. This study aimed to pilot test an online survey instrument evaluating horse owner and trainer perceptions of proper hoof care and balance. The survey instrument sought to collect demographic information of horse owners and trainers, determine horse owners’ and trainers’ abilities to identify ideally balanced equine forehooves, and assess horse owner and trainer knowledge of best hoof trimming and shoeing practices. Ninety-one horse owners and trainers with facilities that were within a 150-mile ...

Uniting For Important Paws: The Independent Cat Society And S.H.I.N.E., Kayla Vasilko

Purdue Journal of Service-Learning and International Engagement

Homeless pets outnumber homeless people 5 to 1; only 1 in 10 animals in animal shelters are spayed or neutered; thus, organizations like the Independent Cat Society (ICS), a non-profit, cage-less, no kill cat shelter are vital community resources (Gaille, 2017). At the ICS, every cat admitted is spayed or neutered and updated on any needed medical treatment; feline overpopulation is addressed through trap, neuter, release (TNR), and additional programs to educate the public on responsible animal care practices (“About the ICS,” 2019). Through volunteerism and two Purdue Service-Learning grants, the Purdue University Northwest student organization S.H.I.N ...

Exploring Children’S Insights About Participating In Recreational Activities With Horses And Farm Animals: Social Emotional Experiences And Belief In Animal Mind, Chrstine Yvette Tardif-Williams Dr., Renata P. S. Roma

People and Animals: The International Journal of Research and Practice

Research continues to shed light on the impact of children’s interactions with horses in equine-assisted, learning, and therapeutic contexts. However, we know relatively less about the impact of children’s recreational activities with horses and a diversity of farm animals. What is needed is research that explores how recreational programs involving activities with horses and farm animals are perceived by the child participants themselves. This pilot study sought to explore the insights of children who participated in a nine-week recreational program involving activities with horses and farm animals, with a focus on children’s social emotional experiences and belief ...

Role Of Dim Artificial Light At Night (Dalan) On Body Weight Percentage Increase Of Mus Musculus, Stephanie A. Babinec

Journal of the South Carolina Academy of Science

Light pollution at night is a growing issue in many suburban and urban settings, commonly referred to as artificial light at night (ALAN). Many studies have been conducted as to how the intensity or wavelength of this lighting can disrupt the circadian rhythm but none have evaluated how the timing of this light could affect it. It is hypothesized that those that chronically experience dim artificial light at night (dALAN) after biological day will lead to a more pronounced disruption in the metabolic system and therefore will cause an increased level of weight gain. Mice were used as test subjects ...

“My Companion Through The Pandemic”: The Importance Of The Human-Animal Bond During Covid-19, Christine Krouzecky, Jan Aden, Anastasiya Bunina, Katharina Hametner, Armin Klaps, Zuzana Kovacovsky, Nora Ruck, Birgit Ursula Stetina

People and Animals: The International Journal of Research and Practice

The COVID- 19 pandemic, due to its global biopsychosocial effects, encourages re-search regarding the promotion of health. Studies in this area concentrate on the human–animal bond as a source of physical and psychological well- being (Shoesmith et al., 2021). In this context, contradictory results have been reported, which on the one hand underline the positive influences of animal companionship on humans’ well- being (Ratschen et al., 2020), and on the other hand demonstrate contrary effects (Mueller et al., 2021). Based on inconsistent findings, the present study aimed to investigate to what extent the human–animal bond influences different psychosocial ...

Attachment to companion animals can play a significant part in clients’ emotional well-being, family dynamics, and quality of life. This study aimed to examine the associations between human attachment with companion animals and their educational training and attitudes about animals. Analysis revealed that relational attachment was significant among Latino students in the study, and particpants’ positive attitudes and beliefs about animals significantly predicted their level of attachment to ...

Dietary Regulation Of Silent Synapses In The Dorsolateral Striatum, Allison M. Meyers

Dissertations, Theses, and Capstone Projects

Obesity and drugs of abuse share overlapping neural circuits and behaviors. Cravings for drugs of abuse increase during abstinence, a phenomenon known as incubation. In obesity, increased craving is observed in individuals during dieting. Diets often fail, with return to- or increase above- original weight. The extent to which this reflects an incubation phenomenon has not been carefully examined. One mechanism underlying incubation is the reemergence of a developmental mechanism called silent synapses. Silent synapses are 'temporary' synapses that are important for remodeling brain circuits. They are prevalent during early development but largely disappear by adulthood. Drugs of abuse increase ...

Investigation Of Neurotransmitter’S Knockdown Effect On Drosophila Melanogaster Female Aggression, Asil N. El Galad

Undergraduate Student Research Internships Conference

Drosophila melanogaster (D. melanogaster) is a popular model organism in neurobiology. While aggression has been studied heavily in male drosophila, there's minimal research on aggression in female drosophila. Neurotransmitters influencing aggressive behaviour in female D. melanogaster are poorly understood. Various neurotransmitters such as dopamine, octopamine, and serotonin influence aggression in D. melanogaster Further investigation of the role of neurotransmitters on aggression is thus important. The purpose of our experiment is to observe the effect of the knockdown of dopamine, octopamine and glutamate on aggression in female D. melanogaster.

Understanding The Views Of Beef Show Cattle Parents And The Reasons Why Their Children Participate In Beef Cattle Shows, Matt Schiel

LSU Master's Theses

The population for this qualitative study were 10 families who participated in showing a heifer at the 2022 Fort Worth Stock Show and Rodeo during the junior heifer show weekend. The families were all from Texas. This study examined why parents allow their children to participate in showing cattle using a case study design. The study was grounded in human capital theory. Interviews and observations were used for the study’s findings. Results showed that the children who showed beef cattle learned responsibility, interpersonal skills, character development, and hard work.

Future research topics include further case studies using the same ...

Assessing The Impact Of Lipopolysaccharide On Learning And Memory In Rats, Anahat Luthra

Undergraduate Student Research Internships Conference

The immune system and the central nervous system (CNS) have a bi-direction relationship, modulating one another.⁴ Proinflammatory cytokines released from CNS immune cells have an impact on cognitive processes such as learning and memory.¹ Liposaccharide (LPS), a cell wall component of Gram-negative bacteria, which is used to activate proinflammatory cytokine release has been found to impact learning and memory processes, such as in the anticipatory nausea paradigm (ANP).² Anticipatory nausea and vomiting is that which may occur before a chemotherapy treatment session begins in a patient who has had chemotherapy before. It is caused by triggers like ...

The Effects Of The Aromatase Inhibitor, Letrozole, On Lithium Chloride (Licl)-Induced Conditioned Disgust Behaviour (Anticipatory Nausea) In Male Rats, Vangel Matic

Undergraduate Student Research Internships Conference

Anticipatory Nausea (AN) is a form of classical conditioning in which the effects of a nausea-inducing toxin become associated with a specific environmental context. AN is often experienced by individuals receiving chemotherapy treatment, whereby the emetic effects of the chemotherapy agents become associated with the treatment context (i.e. hospital, clinic), such that exposure to the context alone can cause an individual to experience nausea and potentially withdraw from treatment. Chemotherapy-associated AN is suggested to have a higher incidence in females compared to males.

AN can be represented in a rodent model (conditioned disgust) through the occurrence of conditioned gaping ...

An Evaluation Of Ethograms Measuring Distinct Features Of Enrichment Use By Captive Chimpanzees (Pan Troglodytes), Julia L. Greeson, Kara I. Gabriel, John B. Mulcahy, Bonnie King Hendrickson, Susan D. Lonborg, Jay C. Holloway

Student Published Works

Environmental enrichment provides mental stimulation and minimizes abnormal behaviors in captive animals. In captive chimpanzees, individual animals may vary in the ways in which they benefit from enrichment or use enrichment devices, so investigating nuances in enrichment use may improve the welfare of captive chimpanzees. In the current study, three ethograms measuring distinct features of enrichment use (i.e., enrichment object, manipulation behavior, and social context) were evaluated by coding videos of captive chimpanzees (Pan troglodytes) at Chimpanzee Sanctuary Northwest in Cle Elum, WA. A total of 732 min and 58 s of video footage was coded from a larger ...

Impacts On Fast-Start Performance: How Do Group Size And Habitat Degradation Alter The Escape Behavior Of A Schooling Coral Reef Fish?, Monica D. Bacchus

All HCAS Student Capstones, Theses, and Dissertations

Escaping predation is essential for species survival, but prey must effectively match their response to the perceived threat imposed by a predator. Fish evaluate their surroundings using several sensory stimuli, including olfactory, visual, auditory, and mechanical cues. A range of taxa use the fast-start response to evade predators, including fishes, sharks, and larval amphibians. While the fast-start response (rapid bursts of swimming) is extensively studied in solitary fishes, the factors that mediate the collective escape response in schools of fish have historically been investigated far less. To address this knowledge gap, the collective escape behavior and individual escape performance of ...

Using Condensed Tannin To Mitigate Tall Fescue Toxicosis, Ally Jo Grote

Graduate Theses and Dissertations

Endophyte-infected (Neotyphodium coenophialum) tall fescue, [Schedonorus arundinaceus (Shreb.)] produces ergot alkaloids. Condensed tannins could bind to ergot alkaloids and render them ineffective. The first objective was to improve the health of sheep offered endophyte-infected tall fescue by binding toxins in the rumen with condensed tannins. Non-toxic novel-endophyte infected tall fescue (NE) or toxic endophyte-infected tall fescue forage was harvested, baled at targeted moisture of 55%, wrapped within 8 hours of baling with 2 layers of net wrap and 20 layers of plastic, and ensiled for at least 60 days. Prior to feeding, forages were chopped and packed into plastic trash ...

Graduate Theses and Dissertations

The purpose of this study was to describe characteristics of collegiate ranch horse teams and team member’s perceived benefits from participation. A lack of research and literature on this category of competition, that is rapidly growing in popularity, is the problem that this study was designed to solve. In recent years, students have begun choosing where to further their education based upon their participation on a ranch horse team. With collegiate ranch horse teams being prevalent, there is a need for a simplified presentation of facts about the teams that can be referenced. This study will be used to ...

Histomonosis In Turkeys – Factors Influencing Transmission, Pathogenesis, And The Search For Prophylactic Or Therapeutic Compounds, Thainá Landim De Barros

Graduate Theses and Dissertations

The incidence of histomonosis has been increasing in poultry since the ban of prophylactic and therapeutic compounds. Histomonosis is caused by the protozoa Histomonas meleagridis. The objective of this dissertation was to investigate factors impacting the pathogenesis and transmission of histomonosis and to evaluate compounds that could potentially prevent or reduce the severity of histomonosis in turkeys. In the first study, the effect of sodium chlorate and sodium nitrate on reducing histomonads growth was tested in vitro and added to a basal turkey diet. A decrease in the growth of histomonads in vitro was observed, but no in vivo effect ...

Effects Of An Injectable Zinc Solution At Weaning As An Alternative Castration Method In Beef Cattle, Reagan Nicole Cauble

Graduate Theses and Dissertations

Two experiments were conducted to investigate a 1 mL intratesticular zinc (100 mg Zn) injection administered into each testicle at weaning (Z) and its effects on growth, health, behavior and testosterone. In the first experiment, beef bulls were assigned randomly to treatment at birth: 1) surgically castrated at birth (S; n = 37) or 2) Z (n = 37). Testicular thickness differed by day (P < 0.01) for Z. Testosterone concentrations were greater in Z by d 77 and remained so through d 280 (P = 0.02) compared to S. Zinc injected calves were heavier at the trail’s conclusion (P ≤ 0.04), had greater ADG overall (P < 0.01), heavier hot carcass weight (P = 0.01), and greater lean muscle area (P = 0.01) compared to S; but a lower marbling score (P < 0.01). Yield Grade, dressed carcass yield and fat thickness were similar (P ≥ 0.14). Zinc injected calves had greater haptoglobin (Hp) concentrations (P < 0.01). Zinc injected calves had greater concentrations of white blood cells on d 1 and 2 and greater concentrations and proportions of neutrophils on d 1, 2 and 3 (P < 0.01). Conversely, S had a greater percentage of lymphocytes on d 1, 2 and 3 and a lower ratio of neutrophils to lymphocytes during that same time (P < 0.01). Zinc injected calves spent more time on their side or sternum on d 1 and more time on their side on d 2 while S spend more time standing during that time (P < 0.01). During d 3, 4, 5, and 6, Z stood more while S laid on their sternum (P < 0.01). In trail 2, beef bulls were allocated randomly to treatment one week post weaning: 1) banded (B; n = 42) or 2) Z (n = 39). Body weights were similar (P ≥ 0.39) but ADG improved for Z compared to B (P = 0.05). Testosterone concentrations were greater in Z compared to B (P ≤ 0.02). Testicular width in Z differed by d (P < 0.01). Zinc castrated calves spent more time on their side compared to B one day post castration (P = 0.03) until d 3 and 4 where B spent more time on their side (P ≤ 0.02). Banded calves stood more the first two days (P ≤ 0.01). On days 3, 4, 5, and 6, Z stood more (P ≤ 0.01) while B were on their sternum (P ≤ 0.03). Banded calves had lower Hp concentrations compared to Z (P ≤ 0.01). Total white blood cell concentrations, proportions and concentrations of neutrophils, and proportion of lymphocytes were greater in Z compared to B on d 1, 2, and 3 (P ≤ 0.01). There was no interaction between treatments over time for IL1β, IL6, and TNFα expression (P ≥ 0.83). The findings in both studies indicate that intratesticular Zn injections at weaning can improve growth performance and some carcass attributes but produce a heightened inflammatory and immune response and cause discomfort. Injecting zinc, as formulated and administered in these trails, does not result in complete castration of beef calves at this age and therefore cannot be considered a true castration alternative.

The Role Of Nest Location On The Reproductive Success Of Piping Plovers Breeding At Rockaway Beach, New York, Clara I.D. Arndtsen

Theses and Dissertations

The study’s goal was to learn what aspects of the piping plover experience affect reproductive outcomes at Rockaway Beach Endangered Species Nesting Area. Nest location was found to help predict reproductive success. Nests further from American oystercatcher nests were likely to fledge more chicks. Reproductive success was low in 2021.

Stakeholders’ Perspectives On The Safety Of An Adaptive Riding Program For Adults Living With Dementia And Care Partners, Alicia A. Oestreich, Beth E. Fields

People and Animals: The International Journal of Research and Practice

The purpose of this qualitative community-based participatory research was to explore the safety perspectives of stakeholders involved in an adaptive horseback riding program designed to enhance the quality of life of adults living with dementia and their care partners. Human–animal interactions are becoming increasingly popular therapeutic interventions; however, there is still a lack of understanding about the safety considerations for providing adults living with dementia opportunities to interact with horses and the equine environment. To advance our understanding, researchers analyzed 10 semistructured interviews and two focus groups with therapeutic riding program instructors and staff, aging network specialists, and care ...

The Effects Of Overshadowing In Drosophila Melanogaster With Experimentally Evolved Preference, Jill Lee

Theses

As seen in decades of psychology research, preferences play a major role in driving the decision-making process in both humans and animals. Researchers have advocated for using the technique of experimental evolution as a way to address some of the foundational questions on preferences. These preferences can also affect what is later learned and how well new experiences are learned. Salience is usually mentioned as an important component of what could influence preferences. Animals such as Drosophila melanogaster, that lay eggs without any additional maternal or paternal care, it is important to be selective when deciding where to lay those ...
