A Survey Of Pet Caretakers On The Use And Perceptions Regarding Heartworm Prophylaxis For Prevention Of Canine Heartworm Disease, Stacie Williams, Charles T. Faulkner

Faculty Other Scholarly Content

Canine heartworm disease (CHWD) is caused by infection with the nematode parasite Dirofilaria immitis transmitted through the bite of a mosquito carrying the infective stage larva. The disease is insidious in its onset and almost 100% preventable with the use of highly effective pharmaceutical compounds that target the migrating larval stage acquired from the mosquito. However, use of canine heartworm prophylaxis among pet dog caretakers is not universally accepted and sometimes viewed with skepticism. Previous research conducted in the Cumberland Gap Region (CGR) indicated that 41.8% of dog owning individuals do not use prophylactic products. In this study, we surveyed …

Screening For Potential Swine-Origin Probiotics With Antimicrobial Activities, Christina Lim

Animal Science Undergraduate Honors Theses

The prevalence of antibiotic resistant bacteria is a leading issue worldwide. Recently, there was a new law banning the use of antibiotics within the swine industry. For decades swine producers have mixed subtherapeutic amounts of antibiotics in swine feed to prevent potential infections and to increase growth rate. However, due to the constant exposure of antibiotics to these ever-evolving pathogens, the population of antibiotic resistant bacteria has increased exponentially. Currently, the swine industry is scrambling to find a suitable alternative to antibiotics that possesses antimicrobial activity and potentially promotes growth. The objective of this study was to investigate the ability …

Poultry Science Faculty Publications and Presentations

Bacterial chondronecrosis with osteomyelitis (BCO) lameness is a bone disease characterized by the translocation of bacteria from the gastrointestinal tract, which colonize microfractures in broiler leg bones caused by rapid animal growth rate and weight gain, resulting in lameness. As such, BCO lameness represents a significant challenge for the poultry industry. This study aims to evaluate the effect of spraying broiler chicks on d0 at hatch with an Enterococcus faecium probiotic on the incidence of BCO-induced lameness, utilizing a Staphylococcus aureus challenge model. There were four treatments: (1) negative control (no probiotic + no challenge, NC); (2) positive control (no …

Toxicological Effects And Treatment Of Accidental Ingestion Of Simparica Trio® In Felis Catus: An Investigative Review, Aussia M. Stander

Honors Program: Senior Projects (Public)

Simparica TRIO^®, a canine endectocide manufactured by Zoetis, contains sarolaner, moxidectin, and pyrantel pamoate salt in an orally administered chewable tablet. These compounds are all toxic to both cats and dogs in sufficient amounts. As Simparica TRIO^® rises in popularity among pet owners, Felis catus (felines, cats) in multi-pet households (households with both cats and dogs) are at increased risk of overdosage and toxicosis from accidental ingestion of Simparica TRIO^® due to their smaller weight.

Simparica TRIO^® is not for feline use and little literature exists on the symptoms of and treatment for accidental ingestion …

Pathology And Osteological Observations Of Early Pliocene Rhinoceros, Teleoceras Aepysoma (Perissodactyla, Rhinocerotidae) From Gray Fossil Site, Tennessee, Thomas Scaife

Electronic Theses and Dissertations

Rhinoceroses were an important part of North America’s Paleogene and Neogene ecosystems, with Teleoceras aepysoma being one of the last representatives of this family. Specimens of T. aepysoma from the Gray Fossil Site (GFS) possess distinct/peculiar pathologies: including a pair of fused ribs and ankylosed phalanges. A qualitative description of the pathologies in the GFS T. aepysoma, including new material, was conducted to accurately identify pathologies and make interpretations about the life history of the GFS rhinos. Analysis suggests that rheumatoid arthritis is common in the lower limb bones of GFS rhinos. Additionally, the rib and toe pathologies are more …

The Effects Of Pre-Parturient Nutrient Restriction On Milk Production, Milk Fat Percentage, Milk Fatty Acid Profile, And Lamb Growth In Sheep, Dakota Murray

All Theses

Cross-bred ewes carrying twins, confirmed via ultrasound, were split into two groups: nutrient-restricted (NR), n=15, and control (CON), n=16. On day (d) 86, at 60% of the NRC requirements, nutrient restriction began and lasted until parturition, at which point ewes were placed back onto a regular diet. After parturition, milk samples and lamb weights were taken on days 1, 7, 14, and 21. Milk lipids were then extracted using modified methods proposed by Hara and Radin (1978). Lipid samples were weighed and then methylated following the procedure outlined by Lock and colleagues (2013). Methylated samples were then analyzed by gas …

The Impact Of A Pgym Variant On Myophosphorylase Deficiency In Red Angus Composite Cattle And Changes In The Skeletal Muscle Transcriptome Due To The Intramuscular Administration Of Lidocaine In Wether Lambs, Mackenzie Christin Batt

School of Biological Sciences: Dissertations, Theses, and Student Research

Project 1 focused on eight calves in a Nebraska herd (composite Simmental, Red Angus, Gelbvieh) that displayed exercise intolerance during forced activity. Available sire pedigrees contained a paternal ancestor within 2-4 generations in all affected calves. Pedigrees of the calves’ dams were unavailable, however, the cows were ranch-raised and retained from prior breeding seasons, where bulls used for breeding occasionally had a common ancestor. Therefore, it was hypothesized that a de novo autosomal recessive variant was causative of exercise intolerance in these calves. A genome-wide association analysis followed by whole-genome sequencing led to the identification of a variant in the …

Impact Of Strategic Postweaning Supplementation On March- And May-Born Yearling Range Heifer And Calf Growth And Performance In The Nebraska Sandhills, Josie Nicole Crouch

Department of Animal Science: Dissertations, Theses, and Student Research

Three experiments were conducted at the Gudmundsen Sandhills laboratory near Whitman, Nebraska. Experiment 1, a retrospective regression analysis, evaluated the impact of heifer percentage of mature body weight (BW) at breeding on heifer performance, subsequent pregnancy rates, and calf production. Overall pregnancy rates were greater (P < 0.01) for heifers at 60 to 70% of mature BW than 50 to 55%, with no differences in pregnancy rates (P ≥ 0.15) after 2-years of age. Heifers at 50 to 60% of mature BW had a greater (P = 0.05) proportion give birth in the first 21-d. A higher percentage of mature BW at breeding resulted in greater (P < 0.01) BW at birth and weaning for offspring.

Experiments 2 and 3 were 3-year studies that evaluated the impact …

Artificial Insemination And Fetal Programming In Beef Production Systems, Dempster M. Christenson

Department of Animal Science: Dissertations, Theses, and Student Research

Pregnancy to artificial insemination and late gestation fetal programming of the next calf crop are central to genetic development, reproductive longevity, calf crop productivity, and efficiency of cow/calf ranching. The purposes of this research are to find methods to improve pregnancy rate to artificial insemination, the growth and reproductive health of pregnant heifers, and the productivity of their offspring. In the first of four studies we found that extending the period of progesterone administration in an estrus synchronization protocol did not significantly hasten estrus response or increase pregnancy rate to artificial insemination, but timing of estrus within the melengestrol acetate …

Cat Color Theory: Can Cat Color Being Accurately Used To Predict Behavior, Emily Mears

Honors Theses

Is there scientific backing for "Tortie-tude" or "Orange Cat Behavior"? Many cat owners swear by these claims. Can coat color predict cat personality? If coat color is an accurate way to predict personality, the cat adoption process could be smoother. Also, veterinarians can be better prepared to avoid cat scratches and bites if they know a color is more likely aggressive. We made and distributed two surveys to determine the perception of personality by color and the actual personalities of cats. The first survey, "Cat Perception," was given to people who work with cats and, therefore, have interacted with a …

Cocoa Polyphenols Modulate The Fecal Microbiome In A Mouse Model Of Colitis, Independent Of Basal Diet And Colon Inflammation, Abby D. Benninghoff

Browse all Datasets

Chronic inflammation increases the risk of developing multiple chronic diseases, including cancer. The risk of developing colorectal cancer (CRC) specifically is increased in individuals who suffer from colitis, a characteristic of Inflammatory Bowel Disease (IBD). Diet is another risk factor for developing CRC, particularly an inflammation-promoting Western-type diet. Thus, supplementing a Western diet with functional foods containing anti-inflammatory polyphenols is a potential approach to decreasing CRC risk by reducing gut inflammation and altering gut microbiome profile. This study aimed to determine the effects of cocoa polyphenol (CP) supplementation on inflammation status and microbiome profile before, during, and after colitis when …
