Influence Of Encapsulation Of Supplemental Amino Acids On Their Utilization In Broilers, Ethan A. Collins

Poultry Science Undergraduate Honors Theses

This study was developed to assess whether microencapsulation of amino acids (AA) improves their absorption to increase broiler growth performance and reduce nitrogen excretion compared to standard feed-grade AA. Five hundred and sixty Ross 708 male broilers were randomly distributed to 70 battery cages and reared for 21 days. Reported data is grouped into periods: 0-7 days, 0-14 days, and 0-21 days. A total of 5 treatment diets were fed: an industry-based control and 4 diets with decreased levels of methionine, lysine, and threonine in either encapsulated or free forms, with or without a botanical feed additive. Encapsulated AA increased …

Black-Capped Chickadee (Parus Atricapillus) Food Preference, Isabelle Gilbert

Thinking Matters Symposium

All animals must make decisions on where to find, select, capture, and eat food. These factors contribute to a species’ food preference, such as making decisions on what food to eat based on calories. Optimal foraging theory predicts how an animal behaves when searching for food, including optimization of food type, patch choice, time spent in patches, and movement. All animals also make decisions based on predation risk by avoiding predators and making trade-offs on time spent searching for, pursuing, and handling food. The objective of my study is to examine food preference of black-capped chickadees (Parus atricapillus). Birds may …

The Impact Of Location And Time Of Day On The Expression Of Social And Physical Maintenance Behaviors In Wild Asian Elephants (Elephas Maximus) In Thailand, Summer Fiori

Theses and Dissertations

Much of what we know about Asian elephant (Elephas maximus) behavioral ecology is the result of long-term ethological studies on wild elephants in India and Sri Lanka or experimental research on captive elephant behavior and cognition. While it is important to study the behavior and ecology of elephants to understand the evolution of adaptations that have made them well-suited for their natural environments, there is also a growing need to study populations of wild Asian elephants for applied conservation purposes. More specifically, elephants are endangered and are facing increasing threats such as human-elephant conflict. In this study, behavioral data …

Pre- And Post-Partum Observations Of Signature Whistle Characteristics Of The Bottlenose Dolphin (Tursiops Truncatus), Robert Dutchen

Theses and Dissertations

This study analyzes whistle usage in an Atlantic bottlenose dolphin during birth. Findings show the mother produces two predominant whistle contours. Congruities between the whistles were compared and showed that the type 1 contour bears structural similarity to the first component of the type 2 contour, indicating combinatorial whistle construction.

Investigating Social Preferences In A High Fission-Fusion Society Of Black And White Ruffed Lemur (Varecia Variegata), Patricia A. Adamo

Theses and Dissertations

Wild lemur primates were tested for social preferences across behaviors. Study found highly conservative social preferences that were very consistent across all behavioral states, despite high fission fusion traits common of lemur groups. This finding lays the foundation for using nearest-neighbor as a proxy of social preference for future endeavors.

Hungry Hungry Humpbacks: A Preliminary Study Of Lunge Feeding In The New York Bight, Samantha E. Smith

Theses and Dissertations

Humpback whales (Megaptera novaeangliae) have been observed feeding in the New York Bight (NYB). Humpbacks in this region have an increased potential for collisions with vessels. In this study, data of lunge feeding was analyzed to determine locations of lunge feeding, clusters of lunge feeding, and depths of lunge feeding.

Bearing Witness To The Beauty Of Enactive Kinesthetic Empathy Across Species In Canine-Human And Equine-Human Interactions: Participant-Observation Ethnographies, Donna A. Carlyle, Pamela Graham

People and Animals: The International Journal of Research and Practice

Through observations from ethnographic fieldwork the authors seek to highlight the significance of equine-human and canine-human communication to the fields of both human- animal studies and eudaimonia theories of human well-being. As we shared our insights through academic conversations about our respective research findings, we realized that both studies explore the enigmatic and significant concept of kinesthetic empathy in communication and relationship building between horses and young people and between dogs and young children. The canine-child setting (Study A) is a primary school and classroom in which the children voted to share their environment with a school dog, and the …

Body States Of Asian Elephants Within And Around Protected Areas In The Salakpra Wildlife Sanctuary, Kanchanaburi, Thailand, Caitlyn Thai

Theses and Dissertations

Researchers are becoming increasingly aware that studying a species’ landscape of fear or, more broadly, their emotional states, can better inform cognitive questions about how animals navigate their environments. Vigilance behaviors are one way to determine how certain species perceive and respond to risky situations. Due to rapid environmental change, large animals such as elephants are experiencing risky encounters with humans more often than ever before. This study aims to investigate Asian elephants’ expressions of body states and how they might regulate their behavior based on perceived environmental risk or change. Specifically, we investigated the behavioral responses of Asian elephants …

249— The Role Of The Indirect Basal Ganglia Pathway In A Mouse Model Of Repetitive Circling Behavior, Gavin Vaughan, Allison R. Bechard

GREAT Day Posters

Repetitive behaviors are associated with a variety of disorders in humans and are diagnostic for autism spectrum disorders. Repetitive behaviors can be modeled in rodents. In our previous experiments, we have been able to reduce repetitive circling behaviors in mice using a ketogenic diet. The mechanisms behind the ketogenic diet are still under investigation. Previous investigations have indicated that the ketogenic diet plays a role in neurotransmitter functioning. This study sought to investigate the potential role of neurotransmitters in repetitive behaviors by investigating how three drugs (L-741,626, a dopamine receptor antagonist; CGS21680, an adenosine agonist; & CDPPB, a glutamate positive …

055— Ketogenic Diet And Dendritic Morphology In A Mouse Model Of Repetitive Behavior, Samantha Seeger, Yume Iriyama, Allison R. Bechard

GREAT Day Posters

Repetitive motor behaviors are invariant movements with no apparent function. They are associated with several disorders, including autism spectrum disorders (ASD). However, little is known about the causes of these restricted behavior patterns, and effective treatments are lacking. ASD has recently been treated with a ketogenic diet (KD). Now a popular fad, KD is a high-fat, low-carb diet that has treated intractable epilepsy for decades. However, the mechanisms mediating KD’s beneficial effects are still unclear. We first show KD can attenuate repetitive circling behavior. We then assessed dendritic spine density in the left and right dorsolateral striatum as a potential …

258— Differential Response To Cocaine In Mice Exposed To Stress, Gavin Vaughan, Melissa Herman, Isabel Ross, Katie Bugbee, April Rowell, Jennifer Bodzon, Allison R. Bechard Ph.D.

GREAT Day Posters

Exposure to trauma is a risk factor for substance use disorders. Using a mouse model of PTSD, we tested the effects of exposure to a stressor (synthetic fox pheromone: TMT) on response to cocaine. Cocaine induced locomotion and cocaine seeking behavior in a conditioned place preference (CPP) were assessed. TMT was an effective stressor, indicated by freezing behavior, which is a known fear response in mice. In both males and females, TMT-exposed mice showed a greater locomotor response to cocaine compared to control mice, resulting in the interaction between time and TMT treatment. TMT-exposed males, but not females, were overall …

The Importance Of Goats In The World, Mahendra Lohani, Dilip Bhandari

Professional Agricultural Workers Journal

It is a challenge to transform the mindset of subsistence farmers to consider goats as a productive asset. Goat health, breeding, housing and nutrition are the main challenges in a smallholder production system. The development of the goat market sector is informal and underdeveloped. As a result, goats have not been identified as a significant contributor to the national gross domestic product. Many development organizations consider goats a preferred livestock commodity for poverty alleviation. Therefore, it is desirable to have a systematic approach to optimize goat production for smallholders. A smallholder goat value chain works well with a focus on …

Sugar Glider (Petaurus Breviceps) Behavior In Red Vs Blue Lighting, Elisa Hillman

Honors Thesis

Sugar gliders are an exotic pet that is increasing in popularity in households as well as in zoos. One challenge that caregivers have to manage is their nocturnal circadian rhythm. In order for people to view or interact with sugar gliders during their active time, many zoos will reverse their diurnal cycle with lights. The discovery of intrinsically photosensitive retinal ganglion cells (ipRGCs) which seems to have an increased sensitivity to blue light and how these cells affect the hypothalamic suprachiasmatic nucleus (SCN) and circadian rhythm has led to an increase in awareness on the health effects of being exposed …

Americans Adopted Fewer Pets From Shelters In 2020 As The Supply Of Rescue Animals Fell, Shelly Volsche

Anthropology Faculty Publications and Presentations

Demand for new pets certainly seemed to spike when the COVID-19 pandemic reached the United States in early 2020 and forced many Americans to spend more time isolated.

But adoptions from animal shelters and rescues actually fell 17% to approximately 1.6 million in 2020 from over 1.9 million in 2019, according to Shelter Animal Counts, a nonprofit that tracks data regarding animals that spend time in shelters.

How did Americans end up welcoming fewer rescued animals into their homes during the COVID-19 pandemic? The short answer is that there weren’t enough furry friends to go around.

Evaluating The Effectiveness Of Empathy-Based Education In The Modern Zoo, Annika Brinkley

WWU Honors College Senior Projects

Approximately 10,000 zoos exist in the world, attracting an estimated 600 million visitors annually. At the most basic level, these zoos are tourist destinations dedicated to assembling animals in confinement from around the world. The arguably most modern and conservation-minded zoos today form the Association of Zoos and Aquariums. In January of 2019, twenty AZA-accredited zoos and aquariums created the Advancing Conservation through Empathy Network (ACE). AZA facilities that are part of the ACE Network engage visitors through a process known as Empathy-Based Education (EBE). EBE encourages compassion and emotional connection to animals by having the visitor take the place …

Sheep Replace Pronghorn: An Environmental History Of The Mono Basin, Robert B. Marks

Eastern Sierra History Journal

This article examines the ways in which the hunting-gathering people of the Mono Basin lived before their way of life and environment was overturned by the nineteenth-century arrival of Euro-American settlers with vastly different ways of interacting with the environment. And it tracks some of these alterations by tracking when and how sheep replaced pronghorns.

Predictors Of Separation Anxiety In Dogs, Mckenna Yohe

Honors Theses

Understanding the potential causes and risk factors associated with separation anxiety in dogs is necessary to provide insight for possible prevention measures and to maintain the health and well-being of the animals affected by this condition. While a considerable amount of research has been done on this subject, it is still unclear what specific characteristics of dogs and their owners relate to the occurrence of separation anxiety and related behaviors. This study aimed to reexamine several dog and owner characteristics that have previously been evaluated in relation to the incidence of separation anxiety, as well as investigate how the frequency …

Sex-Specific Variation Of Social Play In Wild Immature Tibetan Macaques, Macaca Thibetana, Tong Wang, Xi Wang, Paul A. Garber, Bing-Hua Sun, Lixing Sun, Dong-Po Xia, Jin-Hua Li

Biology Faculty Scholarship

Theories proposed to explain social play have centered on its function in establishing social relationships critical for adulthood, its function in developing motor skills needed to survive, and promoting cognitive development and social learning. In this study, we compared variations in social play among infant and juvenile male and female Macaca thibetana. Given that this species is characterized by female philopatry and male dispersal, we hypothesized that immature females use social play as a mechanism to develop bonds that persist through adulthood whereas immature males use play to develop social skills needed to successfully enter new groups. The results indicated …
