Managing Cattle Market Risk With Lrp Insurance, Jay Parsons

Cornhusker Economics

Price and market uncertainties pose a significant risk to cattle producers with a substantial amount of money invested in breeding livestock, land, and other infrastructure. Price protection through the Chicago Mercantile Exchange (CME) futures contracts and options can be used to help mitigate this risk but, in the case of futures contracts, they can also introduce financial burdens in the form of margin calls. Furthermore, many medium to small-scale producers prefer not to get involved with trading futures and options contracts.

Four Legs Good, Two Legs Bad: How Slaughterhouse Safety Hasn’T Kept Up With The Times, Emily Ziemski

Capstones

From legal loopholes and outdated rules to undetectable infections and understaffing, the United States Department of Agriculture may not be doing all it can to make sure the American public’s health isn't at risk. As the people of the United States consume over 500 million pounds of beef a year, food safety policy and slaughterhouses are falling behind in proper procedural measurements in the beef industry.

Evaluation Of Genetic Diversity And Stability Of Colocasia Cultivars Using Issr, Seukmin Hong

Electronic Theses and Dissertations

Using 44 ornamental Colocasia cultivars planted at Stephen F. Austin State University (Nacogdoches, TX), cultivar assessment, genetic diversity, stability, and relationship were examined with banding patterns produced from Inter-simple sequence repeat (ISSR) markers. Comparing banding patterns of vegetatively propagated clones of each cultivar, genetic stability was examined. Unweighted pair group method with arithmetic mean (UPGMA) and principal coordinate analysis (PCO) were performed to examine genetic relationship that can explain a need for the new classification Colocasia gigantea and recent movement of re-classifying Colocasia antiquorum. Average Shannon’s diversity index for all loci was found to quantify genetic diversity. The genetic …

An Introduction To The Economic Impact Of Dry Edible Bean Production, Timothy Meyer

Cornhusker Economics

Amazing statistics about Nebraska agriculture are plentiful. For example, Nebraska produces the 4th most output of agricultural products in the United States, while ranking only 37th in population. No wonder Nebraska's agricultural output ranks first when adjusted for population. It is safe to say most Nebraskans understand the importance of beef, corn, soybeans and ethanol. On the other hand, secondary crops play an important role in the economy as well, especially in the western portion of the state.

The Aid Effectiveness Architecture In Africa: An Analysis Of Aid Structures In Kenya’S Agriculture Sector, Daniel Kipleel Borter

International Journal of African Development

This study examines in detail the development aid architecture in Kenya’s agriculture sector. The focus is on the mechanisms in place within the Kenyan government (and ministry of agriculture in particular), mechanisms among and within donor agencies, and overall coordination mechanisms that bring together the donors and the government. Findings show that coordination and harmonization activities among donors are yet to yield the desired outcomes such as the division of labor protocol and joint programming. Weaknesses are also observed on the government side where it appears authorities are yet to internalize PD concepts and interpret them to suit the country's …

Optimization Of Parameters For The Densification (Pelletization) Of Cereal Crop Residues And Feasibility Study Of Pellet Plant Development In The State Of Arkansas From Economic Perspective, Shyam Thapa

Student Theses and Dissertations

Conventional cereal crop residues, namely, rice (Oryza sativa L.), corn (Zea mays L.), and wheat (Triticum aestivum L.) is very abundant and readily available widely. It has been a nuisance to agronomic producers to manage these immense “so-called wastes”. The Energy Independence and Security Act (EISA) promulgated by the United States and The EU’s renewable energy directive mandated the substantial incorporation of renewable energy in their final energy consumption. These led to the increase in R&D’s on biomass and bioenergy products in the United States as well. Hammer mill grinds of different cereal crop residues, rice, wheat, and corn, sieved …

Demand And Risk Management Analysis Of Rainfall Index Insurance, Ashlee Carlson

Department of Agricultural Economics: Dissertations, Theses, and Student Research

This thesis has two research chapters regarding the government provided Rainfall Index Insurance for Pasture, Rangeland, and Forage (RI-PRF). In the first chapter, we empirically examined whether charity hazard exists between Rainfall Index Insurance (RI-PRF) and government mandated Livestock Forage Program by estimating the demand for RI-PRF. Evidence was found that lagged LFP payments significantly increase the marginal effects of participating in RI-PRF in three of the five states and in the combined model. These results support the opposite of charity hazard where LFP payments improve the probability of purchasing RI-PRF. In our other models, the results provide evidence in …
