Mechanical Properties Of Canine Patella-Ligament-Tibia Segment., Jeffery Biskup, Andy Freeman, W Camisa, J Innes, Michael Conzemius

Jeffery Biskup, DVM, DACVS

OBJECTIVE: To test the ex vivo mechanical properties of canine patella-ligament-tibia (PLT) segment and establish the relationship between donor size and PLT dimensions to the mechanical properties of PLT grafts.STUDY DESIGN: Ex vivo mechanical testing study. SAMPLE POPULATION: Canine PLT segments (n = 21 dogs; 42 PLT). METHODS:Morphometric measurements of PLT segments were taken from computed tomography (CT) images and compared with results obtained using calipers. PLT were tested to failure at a rate of 100% length/s. Mechanical properties and failure mode were recorded. RESULTS: PLT width and thickness (P < .001 for both) measured by calipers were significantly lower than those taken from CT images. Thirty-five (83%) specimens failed by avulsion fracture from the patella, 1 failed mid-ligament, and 6 failed by tibial fracture. Dog weight and PLT length had the strongest Pearson's r value when correlated with load at failure (r = 0.73, 0.81, respectively). CONCLUSION:Dog weight and PLT length were the best predictors of load at failure. PLT failure load of dogs weighing >25 kg were similar to those reported for ...


The Effects Of Music On Dairy Production, Anneliese Kemp Dec 2020

The Effects Of Music On Dairy Production, Anneliese Kemp

Honors College Theses

The purpose of this research is to find which genre of music dairy cows produce the most milk to in order to aid dairy farmers in yielding maximum product while also keeping their cattle as comfortable as possible. During each lactation a different genre of music will play, basic vital signs, and behavioral observations of the cows will be taken, then the amount of milk produced during that genre will be measured. First, no music will be played, base line vitals will be taken, and milk yield will be measured. This will give an estimate to how positively or negatively ...

Poor induction of mucosal immunity in the intestines by current Salmonella vaccines is a challenge to the poultry industry. We prepared and tested an oral deliverable Salmonella subunit vaccine containing immunogenic outer membrane proteins (OMPs) and flagellin (F) protein loaded and F-protein surface coated chitosan nanoparticles (CS NPs) (OMPs-F-CS NPs). The OMPs-F-CS NPs had mean particle size distribution of 514 nm, high positive charge and spherical in shape. In vitro and in vivo studies revealed the F-protein surface coated CS NPs were specifically targeted to chicken immune cells. The OMPs-F-CS NPs treatment of chicken immune cells upregulated TLRs, and Th1 ...

Photographic Validation Of Target Versus Nontarget Take Of Brown Treesnake Baits, Shane R. Siers, Aaron B. Shiels, Cynthia G. Payne, Francinem M. Chlarson, Craig S. Clark, Stephen M. Mosher

USDA National Wildlife Research Center - Staff Publications

Use of toxic baits or other tools for managing nuisance species must ensure that the species of interest is adequately targeted while exposure to nontarget species is minimized. Nontarget takes of acetaminophen‐laced baits for control of invasive brown treesnakes (Boiga irregularis) on Guam may put those animals at risk of lethal intoxication and render the bait unavailable to the intended target species. We used wildlife cameras to identify species removing toxic and nontoxic baits from brown treesnake bait stations designed to exclude nontarget taxa in 2015 and 2016. Throughout various sites and habitat types, and balanced by season (wet ...


Time Allocation To Resources By Three Species Of Rats (Rattus Spp.) In A Radial Arm Maze, Gary Witmer, Nathan P. Snow, Rachael S. Moulton May 2020

Time Allocation To Resources By Three Species Of Rats (Rattus Spp.) In A Radial Arm Maze, Gary Witmer, Nathan P. Snow, Rachael S. Moulton

USDA National Wildlife Research Center - Staff Publications

Context. Introduced rats (Rattus spp.) can pose a serious threat to native flora and fauna, especially on islands where most species have evolved in the absence of terrestrial predators. Effective detection and eradication methods for introduced rats are essential to the maintenance of insular ecosystem integrity. Thus, it is important to better understand the behaviour of rats when they first arrive in a new setting.

Aims. To determine whether rats would find some novel stimuli to be significantly more attractive than other novel stimuli.

Methods. An eight-arm radial maze was used to study the behaviour of three species of Rattus ...


Interactions With Humans Shape Coyote Responses To Hazing, Julie K. Young, Edd Hammill, Stewart W. Breck May 2020

Interactions With Humans Shape Coyote Responses To Hazing, Julie K. Young, Edd Hammill, Stewart W. Breck

USDA National Wildlife Research Center - Staff Publications

Medium and large carnivores coexist with people in urban areas globally, occasionally resulting in

negative interactions that prompt questions about how to reduce human-wildlife conflict. Hazing,

i.e., scaring wildlife, is frequently promoted as an important non-lethal means for urbanites to reduce

conflict but there is limited scientific evidence for its efficacy. We used a population of captive coyotes (Canis latrans) to simulate urban human-coyote interactions and subsequent effects of hazing on coyote behavior. Past experiences with humans significantly affected the number of times a coyoteapproached a human to necessitate hazing. coyotes that had been hand fed by adults had ...

Deciphering Interactions Between White-Tailed Deer And Approaching Vehicle, Morgan Pfeiffer, Raymond B. Iglay, Thomas W. Seamans, Bradley F. Blackwell, Travis L. Devault

USDA National Wildlife Research Center - Staff Publications

Deer-vehicle collisions are a major transportation hazard, but factors affecting deer escape decision-making in response to vehicle approach remain poorly characterized. We made opportunistic observations of deer response to vehicle approach during daylight hours on a restricted- access facility in Ohio, USA (vehicle speeds were ≤64 km/h). We hypothesized that animal proximity to the road, group size, vehicle approach, and ambient conditions would affect perceived risk by white-tailed deer (Odocoileus virginianus) to vehicle approach, as measured by flight-initiation distance (FID). We constructed a priori models for FID, as well as road-crossing behavior. Deer responses were variable and did not ...


The Comparative Cytotoxicity Of Riddelliine In Primary Mouse, Rat And Chick Hepatocytes, Bryan L. Stegelmeier, William S. Resager, Steven M. Colegate May 2020

The Comparative Cytotoxicity Of Riddelliine In Primary Mouse, Rat And Chick Hepatocytes, Bryan L. Stegelmeier, William S. Resager, Steven M. Colegate

Poisonous Plant Research (PPR)

Dehydropyrrolizidine alkaloid (DHPA) producing plants commonly poison livestock, wildlife and humans. Poisoning occurs when DHPAs are ingested as feed or food, or when they contaminate medicinal or herbal products. Direct toxicologic comparison of individual DHPAs is essential to estimate their actual health risks. This has been problematic due to varying models and difficulties in DHPA isolation or synthesis. In contrast, the macrocyclic DHPA riddelliine is readily isolated and it has been used as a benchmark to characterize different models of toxicity and carcinogenicity. Following earlier work with immortalized cell lines, the objective of this study was to characterize the effect ...


Long-Term Implications Of Neonatal Canine Caudectomies, Estefania Benavides May 2020

Long-Term Implications Of Neonatal Canine Caudectomies, Estefania Benavides

Honors College Theses

Tail docking is an ongoing procedure several canine breeders choose to practice in order to preserve the expected appearance of certain breeds, as defined by the American Kennel Club (AKC). The spinal nerves are severed between the two caudal vertebrae of the neonate without the use of any anesthetics, local or general. The inability for the neonates to properly metabolize anesthetics contraindicates its administration. According to the American Veterinary Medical Association (AVMA), only two states in the United States have any sort of provision regarding canine caudectomies, and they are Maryland and Pennsylvania Generally in other states, experienced breeders and ...


Use Of Diatomaceous Earth And Copper Oxide Wire Particles To Control Gastrointestinal Nematodes In Lambs, Olivia Jones May 2020

Use Of Diatomaceous Earth And Copper Oxide Wire Particles To Control Gastrointestinal Nematodes In Lambs, Olivia Jones

Animal Science Undergraduate Honors Theses

Abstract

Anthelmintic resistance (AR) urges alternatives to control gastrointestinal nematodes (GIN). Copper oxide wire particles (COWP) are more efficacious when used with other dewormers and little is known on efficacy of diatomaceous earth (DE) to control gastrointestinal parasites. The objective was to examine the effects of DE and COWP on GIN control. Katahdin lambs (n = 32; ~150 d of age; 25.0 ± 1.8 kg) were randomly assigned to receive: 1) DE fed at an estimated 2% dry matter intake (with the assumption of moderate consumption of bermudagrass forage and provided supplement), 2) 1g COWP, 3) both 2% DE and ...

The Efficacy Of Extended-Release Eprinomectin For The Reduction Of Horn Flies, Face Flies, And Fecal Egg Counts Of Parasitic Nematodes In Replacement Beef Heifers, Sophia F. Landers

Animal Science Undergraduate Honors Theses

The purpose of this study was to evaluate the efficacy of extended-release eprinomectin against horn flies, face flies, and fecal egg counts of parasitic nematodes in crossbreed replacement beef heifers. Fifty-four heifers were randomly placed into three treatment groups (N=18 heifers/treatment). Group 1 was administered the labeled dosage of extended-release eprinomectin on day 0. Group 2 acted as the negative control. Group 3 received the anthelmintic injection once a quarter of the heifers in the group reached the threshold treatment level for horn flies (N=200 flies/animal; day 41). Nematode infections were measured via fecal egg counts ...

Evaluation Of Locally Injected Mycobacterium Cell Wall Fraction In Horses With Sarcoids, Stephanie S. Caston, Brett A. Sponseller, Katarzyna A. Dembek, Jesse M. Hostetter

Veterinary Clinical Sciences Publications

A reformulation of Mycobacterium cell wall fraction immunotherapeutic can be used to successfully treat sarcoids in horses. Sarcoids are reported to be the most common equine skin tumors with tumor type and location influencing the choice of treatment. Wide surgical excision is curative for many tumors, but may not always be feasible. Previous studies have reported sarcoid regression after injection with mycobacterial cell wall immunotherapeutics. A new formulation of the Mycobacterium phlei cell wall fraction immunostimulant (Immunocidin® Equine) was utilized to treat cutaneous tumors in horses. Equids with skin tumors diagnosed as sarcoids were enrolled in the study. Sarcoids were ...


Analysis Of The Osteopathology In A Captive-Born Spectacled Bear, Savannah Vaz Apr 2020

Analysis Of The Osteopathology In A Captive-Born Spectacled Bear, Savannah Vaz

Georgia College Student Research Events

Osseous tissue contains the preserved record of an organism’s diseases and injuries that can be uncovered by examination of the present skeletal abnormalities. This study provides a thorough inspection of osteopathology and its etiology in a modern ursid with a known medical history. The skeletal remains of a captive-born spectacled bear (Tremarctos ornatus) were analysed for gross pathologies that manifested during the life of the animal. All observed osteopathologies were correlated with diseases experienced in the life of the individual, most of which were age-related. However, pythiosis, the grounds for his euthanization, may have contributed to some of the ...


Drowning Of Pet Owners During Attempted Animal Rescues: The Avir-A Syndrome, John Pearn, Amy E. Peden, Richard Charles Franklin Apr 2020

Drowning Of Pet Owners During Attempted Animal Rescues: The Avir-A Syndrome, John Pearn, Amy E. Peden, Richard Charles Franklin

International Journal of Aquatic Research and Education

The rescuer who drowns can result from the attempted rescue of a human or an animal. We report here a total population analysis of all drowning fatalities for the 14-year period 1–July-2002 to 30-June-2016 which involved an attempted rescue of an animal. Cases were drawn from the Royal Life Saving National Fatal Drowning Database, which in turn, derived its data primarily from the National Coronial Information System (NCIS). Eight people drowned, all adults (ranging in age from 19-74 years), in the attempted rescue of an animal. Seven of the animals were domestic pet dogs, and in two cases farm ...

Jergens, Woojung Shin, Soyoun Min, Todd Atherly, Dana C. Borcherding, Jinah Jang, Karin Allenspach, Jonathan P. Mochel, Hyun Jung Kim

Biomedical Sciences Publications

Recent advances in canine intestinal organoids have expanded the option for building a better in vitro model to investigate translational science of intestinal physiology and pathology between humans and animals. However, the three-dimensional geometry and the enclosed lumen of canine intestinal organoids considerably hinder the access to the apical side of epithelium for investigating the nutrient and drug absorption, host-microbiome crosstalk, and pharmaceutical toxicity testing. Thus, the creation of a polarized epithelial interface accessible from apical or basolateral side is critical. Here, we demonstrated the generation of an intestinal epithelial monolayer using canine biopsy-derived colonic organoids (colonoids). We optimized the ...

Veterinary Clinical Sciences Publications

Mucopolysaccharidosis (MPS) is a metabolic storage disorder caused by the deficiency of any lysosomal enzyme required for the breakdown of glycosaminoglycans. A 15-month-old Boston Terrier presented with clinical signs consistent with lysosomal storage disease including corneal opacities, multifocal central nervous system disease and progressively worsening clinical course. Diagnosis was confirmed at necropsy based on histopathologic evaluation of multiple organs demonstrating accumulation of mucopolysaccharides. Whole genome sequencing was used to uncover a frame-shift insertion affecting the alpha-L-iduronidase (IDUA) gene (c.19_20insCGGCCCCC), a mutation confirmed in another Boston Terrier presented 2 years later with a similar clinical picture. Both dogs were homozygous ...

Dynamics Of Larkspur (Delphinium Barbeyi) Pellet Consumption And Tolerance Of The Inhibitory Effects Of Larkspur Alkaloids On Muscle Function In Cattle., Benedict T. Green, Jim Pfister, Dale Gardner, Kevin Welch, Daniel Cook

Poisonous Plant Research (PPR)

Larkspurs (Delphinium spp.) are toxic native plants on foothill and mountain rangelands in western North America, which poison cattle grazing on those rangelands. The purpose of this study was to examine in a laboratory setting, the subclinical effects of larkspur intake and toxicosis, by allowing larkspur susceptible and resistant cattle to self-select the amount of larkspur consumed in pellet form. We hypothesized that there would be differences in short term (9 – 11 day) pellet consumption between susceptible and resistant animals. Two trials were completed, each with larkspur resistant and susceptible Angus steers, and larkspur-alfalfa pellets at a 12% and 6 ...

Papers in Veterinary and Biomedical Science

For more than 30 years, lipid droplets (LDs) were considered as an inert bag of lipid for storage of energy-rich fat molecules. Following a paradigm shift almost a decade ago, LDs are presently considered an active subcellular organelle especially designed for assembling, storing and subsequently supplying lipids for generating energy and membrane synthesis (and in the case of hepatocytes for VLDL secretion). LDs also play a central role in many other cellular functions such as viral assembly and protein degradation. Here, we have explored the structural and functional changes that occur in hepatic and adipose tissue LDs following chronic ethanol ...

(-)-Α-Pinene Reduces Quorum Sensing And Campylobacter Jejuni Colonization In Broiler Chickens, Katarina Šimunović, Orhan Sahin, Jasna Kovač, Zhangqi Shen, Anja Klančnik, Qijing Zhang, Sonja Smole Možina

Veterinary Microbiology and Preventive Medicine Publications

Campylobacter jejuni is one of the most prevalent causes of bacterial gastroenteritis worldwide, and it is largely associated with consumption of contaminated poultry. Current Campylobacter control measures at the poultry production level remain insufficient, and hence there is the need for alternative control strategies. We evaluated the potential of the monoterpene (-)-α-pinene for control of C. jejuni in poultry. The antibacterial and resistance-modulatory activities of (-)-α-pinene were also determined against 57 C. jejuni strains. In addition, the anti-quorum-sensing activity of (-)-α-pinene against C. jejuni NCTC 11168 was determined for three subinhibitory concentrations (125, 62.5, 31.25 mg/L) over ...


Development And Diagnostic Application Of Monoclonal Antibodies Against Swine Acute Diarrhea Syndrome Coronavirus (Sads-Cov), Molly Kroeger Apr 2020

Development And Diagnostic Application Of Monoclonal Antibodies Against Swine Acute Diarrhea Syndrome Coronavirus (Sads-Cov), Molly Kroeger

Schultz-Werth Award Papers

Swine Acute Diarrhea Syndrome Coronavirus (SADS-CoV) is a member of the Coronaviridae family. The virus is associated with severe small intestine inflammation and diarrhea in suckling piglets. In 2017, SADS-CoV was first detected and identified as the causative agent of a devasting swine disease outbreak in southern China. Routine monitoring and early detection of the source of infection is therefore integral to the prevention and control of a SADS-CoV outbreak in the United States. However, the United States does not currently have any diagnostic or surveillance tests to identify this emerging disease. To address these industry needs, we developed monoclonal ...


Development And Management Of Canine Adverse Food Reactions And Its Connections To The Grain-Free Dog Food Movement, Savannah Dunn Apr 2020

Development And Management Of Canine Adverse Food Reactions And Its Connections To The Grain-Free Dog Food Movement, Savannah Dunn

Senior Honors Theses

Canine Adverse Food Reactions include immunologically-mediated food allergies as well as non-immunological food intolerances. Although popular belief holds grains are responsible for AFR, the majority are aggravated by the common protein sources found in commercial dog foods. Elimination diets, a time-intensive method in which suspected allergens are removed from the dog’s diet, are the most effective form of diagnosis, though alternative techniques including patch testing and serum antibody tests have been explored. Presently, avoidance of allergens is the recommended management approach. The erroneous association of grains with AFR has led to the rise of grain-free dog food. However, these ...


Canine Models Of Inherited Musculoskeletal And Neurodegenerative Diseases, Brett D. Story, Matthew E. Miller, Allison M. Bradbury, Emily D. Million, Dongsheng Duan, Toloo Taghian, Dominik Faissler, Deborah Fernau, Sidney J. Beecy, Heather Gray-Edwards Mar 2020

Open Access Articles

Mouse models of human disease remain the bread and butter of modern biology and therapeutic discovery. Nonetheless, more often than not mouse models do not reproduce the pathophysiology of the human conditions they are designed to mimic. Naturally occurring large animal models have predominantly been found in companion animals or livestock because of their emotional or economic value to modern society and, unlike mice, often recapitulate the human disease state. In particular, numerous models have been discovered in dogs and have a fundamental role in bridging proof of concept studies in mice to human clinical trials. The present article is ...

Measuring Cmi Responses Using The Primeflow Rna Assay: A New Method Of Evaluating Bvdv Vaccination Response In Cattle, Shollie M. Falkenberg, Rohana P. Dassanayake, John D. Neill, Paul H. Walz, Eduardo Casas, Julia F. Ridpath, James A. Roth Mar 2020

Measuring Cmi Responses Using The Primeflow Rna Assay: A New Method Of Evaluating Bvdv Vaccination Response In Cattle, Shollie M. Falkenberg, Rohana P. Dassanayake, John D. Neill, Paul H. Walz, Eduardo Casas, Julia F. Ridpath, James A. Roth

Veterinary Microbiology and Preventive Medicine Publications

Current methods for evaluating bovine viral diarrhea virus (BVDV) vaccination response typically rely on measurement of humoral responses as determined by virus neutralizing antibody titers (VNT) against BVDV. While VNT are correlated with increased protection, research has also shown that cell mediated immunity (CMI) is an important component of a protective response against BVDV. For example, improved protection against BVDV by modified-live viral (MLV) vaccines as compared to killed vaccines is thought to be due to better CMI induced by the MLV. The goal of this work was to evaluate the cell mediated response in vaccinated calves using a novel ...

The wild pig population on Molokai, Hawaii, USA is a possible reservoir for bovine tuberculosis, caused by Mycobacterium bovis, and has been implicated in decades past as the source of disease for the island’s domestic cattle. Heat-inactivated vaccines have been effective for reducing disease prevalence in wild boar in Spain and could prove useful for managing M. bovis in Molokai wild pigs. We designed an experiment to test this vaccine in wild pigs of Molokai genetics. Fifteen 3–4-month-old pigs were orally administered 106–107 colony forming units (cfu) of heat-inactivated M. bovis (Vaccinates; n = 8; 0 ...
