Effect Of Percent Fines In Pelleted Diets On Growth Performance Of Grow-Finish Pigs During Three Phases Of Production, Patrick A. Badger, Haley K. Otott, Adam Donnelly, Charles R. Stark, Chad B. Paulk
Kansas Agricultural Experiment Station Research Reports
Swine feed is commonly pelleted to improve F/G, feed handling characteristics, and bulk density. However, the degree of improvement in F/G of pigs depends on pellet quality or the percent fines at the feeder. The objective of this study was to determine if the response to pellet quality was dependent on the BW range of grow-finish pigs. Therefore, a total of 350 pigs (initially 80 lb; line 600 × 241, DNA) were randomly placed in 35 pens with 10 pigs per pen (5 barrows and 5 gilts per pen). All pigs were fed a common diet until the onset of …

Kansas Agricultural Experiment Station Research Reports
Salmonella enterica serotype 4,[5],12:i:- (STM) has become an increasing problem for food safety and has been often detected in pork products. For this study, weanling pigs were exposed to STM-contaminated feed, water, or air to determine possible STM transmission routes. An uninoculated control group of pigs was included. The STM was monitored daily in feces and rectal and nasal swabs. The STM colonization was most prevalent in tissues from tonsil, lower intestine, and mesenteric lymph nodes. No differences in lesion severity were observed between inoculated and control pigs. Contaminated feed, water, and aerosolized particles caused infection in weaned pigs; however, …

In this study, we consider how farmed animals, specifically pigs and chickens, are visualised in literature designed for circulation within animal production industries. The way breeding companies create and circulate images of industrial animals tells us a lot about their visions of what industrial animals are and how they believe animals should be treated. Drawing upon a wide range of material designed for circulation within animal production industries, from the 1880s to the 2010s, this paper examines how representations of pigs and chickens contribute to stories of perfection and advance ideals of power, race, gender, and progress. We demonstrate that …

Application Of Confocal Microscopy To Study The Neural Mechanisms Underlying Insect And Rodent Behavior, Christian Michelle Harris
Theses, Dissertations and Capstones
Posture and walking require support of the body weight, which is thought to be detected by sensory receptors in the legs. Specificity in sensory encoding occurs through the morphological properties of the sense organs (numerical distribution, receptor size) and their physiological response characteristics. These studies focus upon campaniform sensilla, receptors that detect forces as strains in the insect exoskeleton. To study the morphology of campaniform sensilla, the sites of mechanotransduction (cuticular caps) were imaged by light and confocal microscopy in four species (stick insects, cockroaches, blow flies and Drosophila). These data indicate that the gradient (range) of cap sizes may …

Mitigation translocation remains a popular conservation tool despite ongoing debate regarding its utility for population conservation. To add to the understanding of the effectiveness of mitigation translocation, in 2017 and 2018 we monitored a population of protected common chuckwallas (Sauromalus ater) following translocation away from the area of construction of a new highway near the South Mountains, Phoenix, Arizona, USA. We removed chuckwallas from the construction right-of-way, paint-marked and pit-tagged them, and then released them in a nearby municipal preserve. We deployed very high frequency radio-telemetry transmitters on a sub-sample of 15 translocated adult chuckwallas. We monitored the …

Asian clams (Corbicula spp.), zebra and quagga mussels (Dreisenna spp.) have invaded and spread throughout North American surface waters. Corbicula and Dreisenna species bio foul aquatic systems, occupy benthic substrates and degrade environments through shell deposition. I explored how Dreissena and Corbicula invasions affect benthic fish and macroinvertebrate communities, and examine how their impacts differ between urban and rural systems, and temperate and tropical climates. Macroinvertebrate and fish communities were evaluated at sites with increasing shell densities in the Rouge, and Huron rivers (MI, USA) using the United States Environmental Protection Agency’s Rapid Bioassessment Protocols (RBP). Urban and rural macroinvertebrate …

Factors Affecting The Sex Ratio Of White-Tailed Deer (Odocoileus Virginianus) Fetuses In Arkansas, Jorista Garrie, Ralph Meeker
Journal of the Arkansas Academy of Science
Health of the mother is known to affect the sex-ratio of the offspring in sexually dimorphic mammals. Both density-dependent and environmental factors (conditions at present, or seasonal conditions the year before) could impact the health of the mother. There are however two opposing hypotheses for whether a mother in good health should invest more in a strong son (that can father many offspring) or in a daughter (that can stay in the same area and use good resources). Fetuses from 1,208 female white-tailed deer (Odocoileus virginianus) were collected over a 10-year period (2002-2012), across 75 counties in Arkansas. …

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 …

Effects Of Covid-19 Mandates On Student Engagement And Management Of Collegiate Equestrian Teams, Travis Fortune
Murray State Theses and Dissertations
Events like a global pandemic can negatively impact how organizations and groups function. From a collegiate perspective, this could include limiting or eliminating participation in co-curricular activities that have positive impacts on student experiences. Students use these events to make new friends, socialize and generate a sense of belonging, and gain interactions outside the classroom. In March 2020, a number of mandated restrictions were put into place in the United States in response to COVID-19, and collegiate equestrian teams' ability to practice and show were negatively impacted. Even though some restrictions were beginning to ease as of Fall 2021, many …

Coyote Management In San Francisco, Matthew Greer
Master's Projects and Capstones
As cities in North America grow, coyotes have become progressively more important species in urban ecosystems. Moreover, as coyotes increasingly use these urban spaces, human-coyote conflicts have become more common, creating a need for new management strategies. This paper will explore how the city of San Francisco could create a new coyote management plan for its highly visible coyote population. San Francisco has had a persistent coyote population since the early 2000s (Todd, 2018). Currently, the coyote population is close to 100 individuals and is still growing (J. Young, Presidio Trust, pers. comm.). To explore this topic a literature review …

The Art Of Amphibian Conservation: Linking In-Situ And Ex-Situ Populations Of Endangered Species Through Genome Banking, Isabella Joann Burger
Theses and Dissertations
Limited breeding success in captive breeding programs has necessitated the development of assisted reproductive technologies (ART) to preserve and increase genetic variation and population numbers of both captive and wild amphibian groups. ART has been shown to be successful in numerous anuran species, and current studies focus on the application of ART in ex-situ populations. The focus of this project is to show that linking in-situ and ex-situ amphibian populations through sperm cryopreservation, genome banking, and in-vitro fertilization is possible, with the goal of increasing gene diversity throughout groups in order to produce self-sustaining, wild populations in the future. Specific …

Going Vegan Or Vegetarian: Motivations & Influences, Faunalytics, Jo Anderson, Marina Milyavskaya
Diet
After studying hundreds of U.S. and Canadian consumers during their transition to vegetarianism or veganism (collectively referred to as veg*nism), a new report from research organization Faunalytics found that 42% of people’s veg*n journeys were motivated by health, 20% by animal protection, and 18% by environmental concern. For animal advocates interested in helping new vegans and vegetarians maintain their change of lifestyle, study results suggest a focus on self-driven motivations (like personal values or moral identity) and experiences with animal advocacy.
