Examining The Capacity Of Nebraska Rangelands For Cattle Production And Evaluating Drought Management Strategies, Kaitlyn L. Cumming
Examining The Capacity Of Nebraska Rangelands For Cattle Production And Evaluating Drought Management Strategies, Kaitlyn L. Cumming
Department of Agricultural Economics: Dissertations, Theses, and Student Research
This thesis has two chapters focusing on the grazing capacity of Nebraska rangelands, and drought management strategies. The first chapter conducts a gap analysis comparing forage supplied by perennial grasslands to the animal unit months (AUMs) required by the cattle. The purpose of this research was to quantify potential AUM supply (i.e., carrying capacity) of grazing lands dominated by perennial grasses on a regional basis in Nebraska to the AUM demand based on cattle inventories and standard production practices in each region of Nebraska. The results suggest that Nebraska is operating at 100% of potential carrying capacity. Harvest efficiency for …
Three Essays On Biofuels, Drought, Livestock, And The Environment, Sunil P. Dhoubhadel
Three Essays On Biofuels, Drought, Livestock, And The Environment, Sunil P. Dhoubhadel
Department of Agricultural Economics: Dissertations, Theses, and Student Research
This dissertation consists of three essays. The first essay examines the impact of the 2012 drought and the biofuels mandate on the U.S. grain and livestock markets. A stochastic equilibrium displacement model is used to analyze the impact on eight commodity markets viz. beef, pork, poultry, corn, distillers’ grain (DG), soybean, soymeal, and ethanol. Among the eight markets, corn and beef are found to be the most vulnerable to drought. The use of Renewable Identification Number (RIN) credits as an instrument to mitigate the impact of drought has limited effectiveness. A mandate waiver of about 23% is required to fully …
