Evaluating The Epidemiology And Management Of Bovine Congestive Heart Failure, Adam Bassett
Evaluating The Epidemiology And Management Of Bovine Congestive Heart Failure, Adam Bassett
School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research
A form of congestive heart failure is increasingly reported as a cause of death in feedlot cattle located at moderate altitude (≤ 1524 m.). Significant knowledge gaps exist in the epidemiology and management of this form of bovine congestive heart failure (BCHF) regarding frequency and timing of BCHF cases and ways in which beef cattle producers and veterinarians can mitigate this condition. These knowledge gaps present major barriers to understanding the mechanism of BCHF and mitigating the consequences of BCHF. The purpose of this thesis is to summarize current knowledge about BCHF, define gaps in knowledge for which more research …

Nicotine affected meiosis during oocyte maturation is associated with poor subsequent embryonic development. The aim of this study was to analyze the effects of nicotine exposure during in vitro maturation (IVM) on the outcomes of in vitro fertilization (IVF) and the expression of gene related development of oocytes and embryos. Immature (germinal vesicle, GV) oocytes were randomly cultured in IVM media containing nicotine at concentrations of 0.0 (control) 2.5, 5.0, and 10.0 mM. After culturing for 24 h, oocytes were assessed for their maturation rate, subjected to IVF and mRNA extraction for gene expression analysis using quantitative real time PCR …

Right-sided congestive heart failure (brisket disease) commonly occurs in cattle raised at elevations >2,500– 3,500 m. We investigated clinical cases resembling brisket disease at a western Nebraska feedyard at a moderate altitude (1,369 m). Over a 15-mo period (2009–2010), we examined 17 cases (16 steers and 1 heifer), all purebred Angus. All animals had clinical right-sided heart failure: brisket and ventral abdominal edema, and severe chronic passive congestion of the liver. Gross examination confirmed right ventricular hypertrophy (left ventricle plus septum: right ventricle weight ratio mean: 1.33 vs. 2.8–4.0 reference interval). Microscopically, all 17 cases had interstitial fibrosis (mean score: …

Chronic wounds are longstanding dermal wounds that do not heal in a normal amount of time and can commonly last for over a year. These wounds plague humans and farm animals alike. Wounds are characterized by chronic inflammation and are often painful, difficult to heal, have a high recurrence rate, and are potentially debilitating. Long term wounds that do not fully heal are distressing for both humans and animals, but understandably more resources have been directed towards humans. Some treatment options for humans may be suitable for adaptation into the field of animal care. Chronic lesions such as bovine digital …
