Response Of Soil Nitrification To The Veterinary Pharmaceuticals Monensin, Ivermectin And Zinc Bacitracin, Magda A. Konopka

Electronic Thesis and Dissertation Repository

Pharmaceutical residues can reach agricultural land through amendment with animal or human waste. Since 2010, a series of replicated plots received annual applications of ivermectin, monensin and zinc bacitracin, either singly or in a mixture, at 0.1 mg/kg and 10 mg/kg concentrations. I collected soil samples before and after the fourth annual application of pharmaceuticals and assayed them for functional changes and amoA gene abundance, a gene needed for ammonia oxidation. In 2013, I exposed the soils to 100 mg/kg in a laboratory experiment which resulted in acceleration of nitrification. Under 10 mg/kg treatments in the field the abundance of …

"Wake Up The Knowledge That You Have": An Assessment Of Community Food Security In Fellsmere, Florida, Susan Marie Tyler

USF Tampa Graduate Theses and Dissertations

In the global industrial agricultural system many people lack access to high-quality nutritious foods and food production techniques are often inefficient and reliant on harsh chemical inputs. While numerous strategies exist to address the disparities present in the global food system, increasingly researchers and practitioners are looking to local food systems for solutions to strengthen community food security (CFS). CFS emphasizes small-scale production strategies such as farmer's markets, community gardens, and consumer supported agriculture. As these efforts evolve, research is needed to understand how these strategies affect communities. To explore a local CFS initiative, qualitative data were collected from community …

An Asian Origin Of Virulent Aeromonas Hydrophila Responsible For Disease Epidemics In United States-Farmed Catfish, Mohammad J. Hossain, Dawei Sun, Donald J. Mcgarey, Shannon Wrenn

Faculty and Research Publications

Unlabelled: Since 2009, catfish farming in the southeastern United States has been severely impacted by a highly virulent and clonal population of Aeromonas hydrophila causing motile Aeromonas septicemia (MAS) in catfish. The possible origin of this newly emerged highly virulent A. hydrophila strain is unknown. In this study, we show using whole-genome sequencing and comparative genomics that A. hydrophila isolates from diseased grass carp in China and catfish in the United States have highly similar genomes. Our phylogenomic analyses suggest that U.S. catfish isolates emerged from A. hydrophila populations of Asian origin. Furthermore, we identified an A. hydrophila strain isolated …

The Public Health Impacts Of Concentrated Animal Feeding Operations On Local Communities, Michael Greger, Gowri Koneswaran

Michael Greger, MD, FACLM

Large-scale farm animal production facilities, also known as concentrated animal feeding operations (CAFOs), release a significant amount of contaminants into the air and water. Adverse health effects related to exposure to these contaminants among CAFO workers have been welldocumented; however, less is known about their impact on the health of residents in nearby communities. Epidemiological research in this area suggests that neighboring residents are at increased risk of developing neurobehavioral symptoms and respiratory illnesses, including asthma. Additional research is needed to better understand community-scale exposures and health outcomes related to the management practices and emissions of CAFOs.

Palatability Of Teff Grass By Horses, Rachel R. Cummins

Animal Science Undergraduate Honors Theses

Most forages commonly used to feed horses have potential detriments including blister beetles or excessive fiber concentrations. Teff grass (T), a warm-season annual forage, has the potential to be a good alternative for horses because of its lack of observed disorders. Our objective was to compare preference by horses for T harvested under different conditions with that of bermudagrass (B) harvested at two maturities. Six different forages were evaluated: T harvested at the late vegetative stage (TLV), at late bloom but that incurred 33 mm of rainfall between mowing and baling (TLBR), with caryopsis visible (TES), or at soft dough …
