Selling Tradition: Impression Management and Draft Animal Agriculture of a Mississippi Farmstead
<p>This thesis is a case study of a family of farmers in Mississippi’s Piney Woods who use horse-drawn equipment to grow crops. This practice is notable in the context of a larger agricultural system that prioritizes mechanization (particularly the use of tractors). The production style and their …

What’s at Steak? The Political Discourse of Emissions Intensity and Implications of Animal Agriculture
… a ratio comparing emissions produced per unit of animal product as oppose to measuring absolute emissions. This research is acknowledged as a win-win scenario which allows for a reduction of greenhouse gas emissions while continuing production more efficiently. This thesis outlines the emergence …

The Impact of Ceftiofur Removal on Recovery of Salmonella enterica and Escherichia coli Resistant to Third Generation Cephalosporins
<p>Ceftiofur use in animal agriculture has been disputed due to the concern over the impact it may be having on the spread of resistance genes among foodborne pathogens. Several attempts to restrict the extra label use of ceftiofur have resulted in failure until the recent FDA ban. No study has …

Estimating Costs of Reducing Environmental Emissions From a Dairy Farm: Multi-objective epsilon-constraint Optimization Versus Single Objective Constrained Optimization
… While water quality concerns related to animal agriculture have been studied extensively, air quality issues have become an increasing concern. Due to the transfer of nutrients between air, water, and soil, emissions to air can harm water quality. We conduct a multi-objective optimization …

Water Quality Performance of a Reciprocating Biofilm Reactor for Treatment of Dairy Wastewater
… and costly process that is rarely implemented in animal agriculture, such as the dairy industry, despite regulatory pressures and the high cost of land for manure application in some regions. This paper describes results from the first implementation for treatment of dairy farm wastewater of the …

Ruminal Nitrogen Recycling and Nitrogen Efficiency in Lactating Dairy Cattle
Excess nitrogen (N) excretion from animal agriculture results in reduced air and water quality, and poses a risk to human health. Although the dairy industry utilizes milk urea N (MUN) to monitor protein feeding and N excretion, phenotypic diversity among cows may influence MUN and thus bias feed …

Evaluation of Manure Management Systems (MMS) and Cost-Share Programs for Mitigating Livestock Environmental Impacts
Animal agriculture is a climate-exposed industry, creating the need to implement climate-smart manure management practices to alleviate manure's pollutive potential through greenhouse gas emissions (GHGe) and excess nutrient management. Manure management systems (MMS) require high initial …

Evaluation of Macrolide-Lincosamide-Streptogramin B Antimicrobial Resistance at Swine Farms
Antimicrobial use in animal agriculture contributes to increased levels of antimicrobial resistance in the environment. To better evaluate this concern, the levels of macrolide-lincosamide-streptogramin B (MLSB) antimicrobial resistance at swine farms were quantified. A variation of fluorescence in …

Development and characterization of DNA markers for two avian species
Central to the application of genomics to animal agriculture are DNA markers, especially microsatellites and single nucleotide polymorphisms. These markers are the resources necessary for constructing genetic maps and for determining how improved and unimproved animal breeds are related. Here, DNA …
