Investigating Egg Storage Conditions, Hatch Characteristics, And Feeding Methods Of Commercially Produced Poultry, Joshua R. Deines

Graduate Theses and Dissertations

Advancements in poultry research continue to add knowledge and understanding to an already technical industry. Such information has led to new developments in early feeding strategies which provide nutrients to broiler chicks while in the egg or during transport. This wealth of knowledge in poultry research extends beyond chickens and is utilized for other species, such as quail and pheasants, including how fertile eggs are stored and incubated. However, methods of early feeding broilers have not been investigated in industry relevant approaches to understand its effects, including how timing of feed access interacts with the hatch window. As well, quail …

The Thai Journal of Veterinary Medicine

Staphylococcus aureusis the leading cause of mastitis in dairy goats and is globally recognized as a significant mastitis-causing pathogen in dairy animals. Previous studies have established it as the causative agent of various human disorders, including food poisoning and Staphylococcal enterotoxins. Furthermore, poor sanitary conditions suit infection by this bacterium. This study determined the occurrence of S. aureusin infected dairy goats by molecular analysis. A hundred raw milk samples were collected from two infected dairy goat breeds (Beetal = 71; Teddy = 29) and cultured on blood agar media. The strain identified as S. aureusby morphological method (Gram staining), biochemical …

Rubber Band Syndrome In A Dyspneic Dog, Nithida Boonwittaya, Saroch Kaewmanee

The Thai Journal of Veterinary Medicine

The rubber band syndrome has been reported inboth human and animal patients but the number of cases shows it is an uncommon condition. Most cases live in communities where a rubber band is commonly used for a wide variety of purposes. Here we report a case of a dyspneic dog with a linear constricting scar and a discharging sinus on the ventral neck. The radiography showed constructive signs. Surgical exploration found a colored rubber band burrowing into the tracheal lumen. Following surgery, the dog recovered without any complications in the postoperative follow-up period. This case emphasized that rubber band syndrome …

Efficacy Of Competitive Exclusion To Reduce Salmonella In Broiler Chickens, Nattaporn Jiratitipat, Prapasri Srikhong, Wisanu Wanasawaeng, Niwat Chansiripornchai

The Thai Journal of Veterinary Medicine

Competitive exclusion (CE) relies on the activity of normal flora to limit intestinal colonization by enteric pathogens. This study aims to investigate the effects of CEon Salmonellainfectionin broilers. The protective effect of CE on Salmonella cecal colonization was evaluated in 1 day-old chicks.In the laboratory trial, CE products were administered by oral inoculation, drinking water and whole body spray. Three days after treatment,the chickens were challenged with 107cfu/mL of SalmonellaEnteritidisorally, and were evaluated for 10 days. The CE-treated chickens showed comparable protection andthe number of Salmonella in the cecal contents significantly decreased(P<0.05)compared with those of the positive control. In the farm trial,CE was administeredby whole body spray at the hatchery and the second was administered by drinking water and evaluated at 32 and 42 days, respectively. The CE significantly reduced Salmonellacontamination in the farm trial andno Salmonellawas detected in the cecal contents compared with the control group. Average body weight gains, feed conversion ratioand theperformance indexof the chickens were greater than thecontrol group. Thus, the use of CEhad a positive effect on broiler performance. Furthermore, the CE-treated chickens displayed greater intestinal histology including villous height, submuscular layerand cell mitosis.These studies demonstrate that CEwas able to protect chickens from Salmonella cecalcolonization and it is apparent that new methodologies associated with the development of a workable CE program are needed in thepoultry industry.

The Impact Of Ergot Alkaloid Consumption During Gestation On Maternal Performance And Fetoplacental Development, Jessica Lynn Britt

All Dissertations

Tall fescue is the primary cool season perennial forage grass in southeastern US for grazing livestock. Tall fescue the is known to be drought tolerant , disease resistant, grazing tolerant and overall very hardy. Many of these attributes common to fescue are due to a symbiotic relationship between the fescue plant and an endophyte, Epichloë coenophiala , which produces a class of mycotoxins known as ergot alkaloids. These ergot alkaloids are similar in structure to several biogenic amines, such as epinephrine, norepinephrine, and dopamine. When consumed, ergot alkaloids cause a syndrome known as fescue toxicosis which causes problems with weight …

The Thai Journal of Veterinary Medicine

Clinical caseouslymphadenitis was observed in 60 of 1,186 goats. A total of 34 small holder goat farms were investigated in 11 provinces in the northeastern part of Thailand. Approximately66.67%of clinical caseous lymphadenitis goats were infected with Corynebacterium pseudotuberculosis,as confirmed by an ELISA test or bacterial culture. The average prevalence of clinical caseous lymphadenitisin herds was 6.36+4.30%(4.86–7.86; 95%CI). The abscessation of a superficial lymph node was commonly found in proximal (46.67%), middle (38.33%), and distal (15%)parts of the body. The location of the lesion was significantly associated (p<0.05)with positivity either from ELISA or bacterial culture, as goats with lesionsinthe distal part of the body showed a higher positivity (90%)than at theproximal (75%)and middle parts(45%)(p=0.02), respectively. No significant difference was observed for goat gender, age, or breed in terms of infection prevalence or displays of clinical signs of caseous lymphadenitis(p>0.05). Controland prevention measures should incorporate client education on a number of factors, …

Male Burmese Pythons Follow Female Scent Trails And Show Sex-Specific Behaviors, Shannon A. Richard, Eric A. Tillman, John S. Humphrey, Michael L. Avery, M. Rockwell Parker

United States Department of Agriculture Wildlife Services: Staff Publications

Animals communicate with potential mates using species-specific signals, and pheromones are powerful sexual signals that modify conspecific behavior to facilitate mate location. Among the vertebrates, snakes are especially adept in mate searching via chemical trailing, which is particularly relevant given that many snake species are invasive outside their native ranges. Chemical signals used in mate choice are, thus, potentially valuable tools for management of invasive snake species. The Burmese python (Python bivittatus) is an invasive snake in the Florida Everglades where it is negatively impacting native fauna. In this study, we sought to: (i) determine if males can follow conspecific …

Variation In Host Home Range Size Decreases Rabies Vaccination Effectiveness By Increasing The Spatial Spread Of Rabies Virus, Katherine M. Mcclure, Amy T. Gilbert, Richard B. Chipman, Erin E. Rees, Kim M. Pepin

United States Department of Agriculture Wildlife Services: Staff Publications

1. Animal movement influences the spatial spread of directly transmitted wildlife disease through host-host contact structure. Wildlife disease hosts vary in home range- associated foraging and social behaviours, which may increase the spread and intensity of disease outbreaks. The consequences of variation in host home range movement and space use on wildlife disease dynamics are poorly understood, but could help to predict disease spread and determine more effective disease management strategies.
2. We developed a spatially explicit individual-based model to examine the effect of spatiotemporal variation in host home range size on the spatial spread rate, persistence and incidence of rabies virus …

Food Habits Of Coyotes (Canis Latrans) In The Valles Caldera National Preserve, New Mexico, Suzanne J. Gifford, Eric M. Gese, Robert R. Parmenter

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife managers needed to understand coyote (Canis latrans) ecology in order to develop management plans on the nascent Valles Caldera National Preserve in northern New Mexico. Managers concerned about low elk (Cervus elaphus) recruitment had observed an increase in sightings of coyotes and observations of coyote predation on elk calves. Our objective was to identify and quantify coyote diet, and assess the temporal variation in coyote diet on the Valles Caldera National Preserve, particularly as related to elk calf consumption. We examined coyote food habits using 1,385 scats analyzed monthly from May 2005 to November 2008. …

Clpc Affects The Intracellular Survival Capacity Of Staphylococcus Aureus In Non-Professional Phagocytic Cells, Gubesh Gunaratnam, Lorena Tuchscherr, Mohamed I. Elhawy, Ralph Bertram, Janina Eisenbeis, Christian Spengler, Thomas Tschernig, Bettina Löffler, Greg A. Somerville, Karin Jacobs, Mathias Herrmann, Markus Bischoff

School of Veterinary and Biomedical Sciences: Faculty Publications

Invasion and persistence of bacteria within host cells requires that they adapt to life in an intracellular environment. This adaptation induces bacterial stress through events such as phagocytosis and enhanced nutrient-restriction. During stress, bacteria synthesize a family of proteins known as heat shock proteins (HSPs) to facilitate adaptation and survival. Previously, we determined the Staphylococcus aureus HSP ClpC temporally alters bacterial metabolism and persistence. This led us to hypothesize that ClpC might alter intracellular survival. Inactivation of clpC in S. aureus strain DSM20231 significantly enhanced long-term intracellular survival in human epithelial (HaCaT) and endothelial (EA.hy926) cell lines, without markedly affecting …

United States Department of Agriculture Wildlife Services: Staff Publications

Human activities frequently result in reptile mortality, but how direct anthropogenic mortality compares to natural morality has not been thoroughly investigated. There has also been a limited examination of how anthropogenic reptile mortality changes as a function of the human footprint. We conducted a synthesis of causespecific North American reptile mortality studies based on telemetry, documenting 550 mortalities of known cause among 2461 monitored individuals in 57 studies. Overall 78% of mortality was the result of direct natural causes, whereas 22% was directly caused by humans. The single largest source of mortality was predation, accounting for 62% of mortality overall. …

Equine Hoof Stratum Internum K14+Cd105+ Progenitor Cells: Culture, Characterization, And Model Of Epithelial To Mesenchymal Transition, Qingqiu Yang

LSU Doctoral Dissertations

For the potential benefit of progenitor cells to be realized in cell-based clinical therapies, it is vital to investigate the mechanism between progenitor cells and abnormal tissue formation. Laminitis is a fatal condition that is often presented by equine hoof inflammation and hoof tissue disarrangement. The persistence of abnormal tissue formation after the resolution of equine laminitis suggests there is progenitor cell compromise. So far, there is limited information about equine hoof progenitor cells and the effects of inflammation on hoof progenitor cells. To pursue a better understanding of both hoof progenitor cell and hoof growth as well as find …

From The Human To The Planetary: Speculative Futures Of Care, Miriam Ticktin

Publications and Research

This is largely a theoretical, speculative essay that takes on the question of what ‘care’ looks like at a moment when climate change is increasingly taking center stage in public and political discussions. Starting with two new practices, namely, humanitarian care for nonhumans and One Health collaborations, I seek to determine what forms of political care can incorporate the well-being of future generations and future iterations of the earth. After an exploration of One Health as an approach to planetary care, I ask what its parts enable us to think, despite its limitations; I focus on the new human-nonhuman assemblages …

North American Hard Yellow Liver Disease: An Old Problem Readdressed, Bryan L. Stegelmeier, Meredyth Jones, Christopher P. Womack, T Zane Davis, Dale R. Gardner

Poisonous Plant Research (PPR)

Hard yellow liver disease or fatty cirrhosis periodically affects cattle, sheep, goats, pronghorn antelope (Antilocapra americana) and whitetail deer (Odocoileus virginianus texanus) within several Texas counties in the United States. Clinically it presents as chronic liver disease with progressive hepatic necrosis and fibrosis, icterus and liver failure. The damaged livers are yellow and many have multiple firm, often gritty foci that are scattered throughout all lobes. Early investigations included feeding studies using potential toxic plants, climate and forage studies, infectious disease surveys and various mycotoxin studies and analyses. None have definitively reproduced the disease or identified the inciting …

Cannibidiol (Cbd) Supplementation In Horses: A Pilot Study, Kiara Jones, Evan Thomas, Shea Porr

Posters-at-the-Capitol

Cannibidiol (CBD) is sold for various uses in humans and animals. Thus far, CBD has not demonstrated effects similar to delta-9 tetrahydrocannabinol (THC), the psychoactive component of marijuana. While some animal species have demonstrated responses to CBD supplementation, published literature on equines is absent. The lack of FDA approval and studies to support claimed benefits make regulating product quality and recommending dosages difficult. The objectives of this project were to: 1) determine dosages that allowed for CBD detection in equine blood; and 2) evaluate time required for the appearance of maximum concentration and half-life of CBD in equine blood. Two …

Nlrp6 In Gram-Positive Pneumonia And Sepsis, Laxman Ghimire

LSU Doctoral Dissertations

Acute lower respiratory infections (pneumonia) and pneumonia-derived sepsis are among the leading causes of death in the world causing 7.8 million deaths annually. In this regard, Methicillin-resistant Staphylococcus aureus (MRSA) is endemic in the US and implicated for causing high mortality-associated necrotizing pneumonia and aggravating viral pneumonia with superinfection. Additionally, sepsis is the 7^th leading cause of death among newborns in the US and is responsible for more than 750,000 hospitalization cases every year. Although there is a plethora of research in both pneumonia and sepsis, the detailed pathophysiology still remains elusive. Understanding the host defense mechanism will help …

Rapports de recherche scientifique

Les éleveurs de porcs du Québec sont quotidiennement exposés à d’importantes quantités de gaz, d’odeurs, de poussières et de bioaérosols. Par conséquent, ils sont à risque de développer des problèmes respiratoires (ex. asthme) ainsi que des maladies infectieuses telles qu’une méningite à Streptococcus suis. Le risque de développer un problème de santé est lié au nombre d’heures passées à l’intérieur des bâtiments d’élevage ainsi qu’aux concentrations des différents contaminants. De plus, les travailleurs peuvent être en contact avec des bactéries résistantes aux antibiotiques soit des bactéries sélectionnées par l’emploi d’agents antimicrobiens utilisés lors de l’engraissement des animaux. Finalement, de …

The Tail Wagging The Dog: Positive Attitude Towards Livestock Guarding Dogs Do Not Mitigate Pastoralists’ Opinions Of Wolves Or Grizzly Bears, Daniel Kinka, Julie K. Young

United States Department of Agriculture Wildlife Services: Staff Publications

While the re-establishment of grizzly bears (Ursus arctos) and wolves (Canis lupus) in the American West marks a success for conservation, it has been contentious among pastoralists. Coincidentally, livestock guarding dogs (LGDs; Canis familiaris) have been widely adopted by producers of domestic sheep (Ovis aries) in the United States to mitigate livestock depredation by wild carnivores. We surveyed pastoralists to measure how experience with and attitudes towards LGDs related to attitudes towards livestock predators, and found positive responses regarding LGDs and negative responses regarding wolves and grizzly bears. The more respondents agreed that LGDs reduce the need for lethal management …

The Changing Role Of Rodenticides And Their Alternatives In The Management Of Commensal Rodents, Gary Witmer

United States Department of Agriculture Wildlife Services: Staff Publications

Rodents cause substantial damage and losses of foodstuffs around the world. They also transmit many diseases to humans and livestock. While various methods are used to reduce damage caused by rodents, rodenticides remain an important tool in the toolbox. However, like all tools, rodenticides have advantages and disadvantages. Several considerations are shaping the future of rodenticide use, including manufacturing and registration costs, concern about toxicity levels and nontarget animal hazards, potential hazards to children, reduced effectiveness of some formulations, and humaneness to the targeted rodents. Many of these disadvantages apply to anticoagulant rodenticides, and their use is being more restricted …

Tracking Canada Geese Near Airports: Using Spatial Data To Better Inform Management, Ryan Askren, Brett E. Dorak, Heath M. Hagy, Michael W. Eichholz, Brian E. Washburn, Michael P. Ward

United States Department of Agriculture Wildlife Services: Staff Publications

The adaptation of birds to urban environments has created direct hazards to air transportation with the potential for catastrophic incidents. Bird–aircraft collisions involving Canada geese (Branta canadensis; goose) pose greater risks to aircraft than many bird species due to their size and flocking behavior. However, information on factors driving movements of geese near airports and within aircraft arrival/departure areas for application to management are limited. To address this need, we deployed 31 neck collar-mounted global positioning system transmitters on Canada geese near Midway International Airport in Chicago, Illinois, USA during November 2015 to February 2016. We used the movement data …
