Effectiveness Of Maternal Bovine Appeasing Substance Administered To Newly Received, High-Risk Stocker Calves, Elle Johnston
Effectiveness Of Maternal Bovine Appeasing Substance Administered To Newly Received, High-Risk Stocker Calves, Elle Johnston
Animal Science Undergraduate Honors Theses
Stocker cattle purchased at auction can be susceptible to disease due to the stressors associated with the auction process. These cattle are labeled “high-risk” due to their compromised immune system during transportation, handling, and vaccination processes. The objective of this study was to determine the efficacy of a maternal bovine appeasing substance, FerAppease, on growth performance and behavior of stocker cattle. Male beef calves (n=80) were purchased at auction and transported to the University of Arkansas Division of Agriculture Savoy Research Complex Beef Stocker Unit. Steers and bulls were of varying age, breed, and temperament. Upon arrival to the facility …
Antimicrobial Peptides: Could It Be An Alternative To Antibiotics In Boar Semen Extender?, Krittika Keeratikunakorn, Panida Chanapiwat, Kampon Kaeoket
Antimicrobial Peptides: Could It Be An Alternative To Antibiotics In Boar Semen Extender?, Krittika Keeratikunakorn, Panida Chanapiwat, Kampon Kaeoket
The Thai Journal of Veterinary Medicine
Since antimicrobial resistance is a major global issue, “One Health” approaches such as the use of antimicrobial peptides (AMPs) was developed as an alternative antimicrobial agent which might be used in pig farms to reduce or replace non-rationale antibiotics usage. Although AMPs showed several effects on antimicrobial agents, including against bacteria, fungi, protozoa, and viruses, as well as effects on host immunity, their most notable property is their ability to kill bacteria without causing damage to the host cell. Two major mechanisms of action of AMPs include membrane-active and intracellular-active. During the past decade, many AMPs have been tested for …
Science-Based Regulation Of Pharmacological Substances In Competition Horses, Jacob Machin
Science-Based Regulation Of Pharmacological Substances In Competition Horses, Jacob Machin
Theses and Dissertations--Toxicology and Cancer Biology
Current testing methodologies within equine forensic toxicology focus on arbitrary thresholds and zero-tolerance policy. Modern analytical chemistry’s limits of detection are low enough that oftentimes femtogram-per-milliliter amounts of a substance can readily be identified in both blood and urine of a horse. For most pharmacologically relevant compounds, these concentrations have no relevance to pharmacological effect. It is therefore crucial that testing methodologies to determine appropriate thresholds and cut-offs be developed that are driven by biological activity rather than arbitrary limits of detection. This dissertation looks to address this by suggesting a system of calculated Effective Plasma Concentrations by which a …

Kisspeptin is a neuropeptide that governs the reproductive axis upstream to GnRH. We wanted to study whether kisspeptin modulates plasma LH and FSH levels and ovarian follicular dynamics in buffaloes and whether kisspeptin can be used for fixed time artificial insemination (FTAI). We carried out these studies in comparison with buserelin, a potent GnRH agonist. Kisspeptin dose-dependently increased plasma LH levels. However, the kisspeptin-induced increase in LH was short-lived as the peak reached in 15–30 min returned to basal values by 1–2 h. The kisspeptin-induced increase in LH level was less compared to buserelin-induced increase in LH level which sustained …
30-Day Oral Acetaminophen Tolerance In Adult Horses, Sarah E. Foreman
30-Day Oral Acetaminophen Tolerance In Adult Horses, Sarah E. Foreman
Celebration of Learning
There are no controlled studies of acetaminophen toxicity in horses. The objective was to test the hypotheses that oral acetaminophen administered at a dosage 25% higher than that sometimes used in horses would result in measurable hepatic toxicity as seen in humans and other species. Six healthy adult horses were administered 25 mg/kg acetaminophen powder in corn syrup twice daily for 30 days. Three other horses served as negative controls receiving only corn syrup. Jugular venous blood samples were obtained on days 7 and 1 before treatment; on treatment days 1, 2, 5, 8, 12, 15, 19, 22, 26 and …

Studies On The Prevalence And Control Of Parasitic Helminths In "Natural" Laying Hens, Brittany R. Weir
Studies On The Prevalence And Control Of Parasitic Helminths In "Natural" Laying Hens, Brittany R. Weir
Animal Science Undergraduate Honors Theses
One societal trend that has been gaining much traction and popularity since the 21st century began is “organic” and/or “natural” food products. In 1999, the global market accounted for $15.2 billion dollars worth of organic food and drink, compared to the market in 2014 where we consumed $80 billion dollars worth (Willer et. al, 2016). With “natural” production of food animals however, “natural” parasite transmission may be a consequence. To that end, this experiment examines the prevalence of helminths in 110 “natural” laying hens from three regional farms and the efficacies of fenbendazole, piperazine, and levamisole on what should …

Many antibiotics and medications used in the treatment of animals have a withdrawal time; residues are a concern for the meat industry. The most recently published 2009 USDA-FSIS Residue Program Data Report listed 135,389 Inspector-in-Charge-Generated (IICG) residue samples from 43,142,500 beef and dairy cattle inspected that year at harvest. Of these samples, 1,306 contained violative antibiotic residues and 327 violative flunixin meglumine residues. Two classes of antimicrobials comprised over half of the documented violative antimicrobial residues (beta-lactams that include ceftiofur and sulfa drugs that include sulfadimethoxine). While the violative residue rate seems small, violative residues are unacceptable. Management of carcasses …
