Evaluating Consumer Acceptability And Willingness To Pay For Various Beef Chuck Muscles, A.C. Kukowski, R.J. Maddock, D.M. Wulf, G.L. Taylor

Animal Science Faculty Publications

In-home consumer steak evaluations, followed by centralized laboratory-setting auctions, were used to determine consumer (n = 74 consumers) acceptability and willingness to pay for various beef chuck muscles. The infraspinatus (IF), serratus ventralis (SV), supraspinatus (SS), and triceps brachii (TB) from the beef chuck were evaluated against LM steaks from the rib to determine price and trait differentials. Muscles from USDA Choice, boneless, boxed-beef subprimals were aged 14 d, frozen, and cut into 2.5-cmthick steaks. Consumers received two steaks from each muscle for in-home evaluations of uncooked steak appearance and cooked steak palatability. After in-home evaluation of steaks, consumers participated ...


Ag Energy: Risk Management, Energy, And Grain Issues, William M. Edwards Oct 2005

Ag Energy: Risk Management, Energy, And Grain Issues, William M. Edwards

Integrated Crop Management News

Nearly everyone has been impacted by higher fuel prices this year. Custom corn and soybean harvesters are no exception. Their increased costs will likely be factored into custom harvesting rates this fall. Estimates of diesel fuel consumption of combining corn range from 1.5 to 2.0 gallons per acre. Soybean harvesting takes only about 1.0 to 1.5 gallons per acre. Larger, newer combines will typically use less fuel per acre.

An Evaluation Of Production And Economic Efficiency Of Two Beef Systems From Calving To Slaughter, R. V. Anderson, Richard J. Rasby, Terry J. Klopfenstein, R. T. Clark Jan 2005

An Evaluation Of Production And Economic Efficiency Of Two Beef Systems From Calving To Slaughter, R. V. Anderson, Richard J. Rasby, Terry J. Klopfenstein, R. T. Clark

Faculty Papers and Publications in Animal Science

A 3-yr experiment was conducted with cows and their calves to evaluate resource inputs, animal performance, and carcass characteristics of two production systems. In the control system, cows (CON; n = 99/yr) grazed pasture and were fed hay during the winter, and CON steer calves were finished in the feedlot for 211 d after weaning. In the treatment system (TRT; n = 100/yr), cows grazed pasture and crop residue during the winter and were fed hay. Treatment steer calves grazed crop residue after weaning, grazed pasture in the spring and summer, and were finished in the feedlot for 90 d ...


Predicting Animals In Feedlot That Produce Discounted Carcasses, Maro A. Ibarburu, John D. Lawrence Jan 2005

Predicting Animals In Feedlot That Produce Discounted Carcasses, Maro A. Ibarburu, John D. Lawrence

Animal Industry Report

U.S. beef producers are striving to improve the quality of their product. Most packers send economic signals to producers by paying quality grade and yield grade premiums based on the USDA standards in an effort to reward the higher quality beef producers and receive better quality animals in their slaughter plants. But the premiums and discounts for quality and yield grade vary between plants and grids. Therefore, identifying the characteristics of the lot before deciding which plant or grid system to sell their cattle is of special relevance for the producers.


Valuing Double Vaccination In Feeder Cattle, Maro A. Ibarburu, Beth E. Doran, J. D. Lawrence Jan 2005

Valuing Double Vaccination In Feeder Cattle, Maro A. Ibarburu, Beth E. Doran, J. D. Lawrence

Animal Industry Report

Pre-conditioning is a calf management program that grew out of a concept that originated in Iowa in 1965. The program is designed to reduce risk, health problems and improve profitability for both cow-calf producers and cattle feeders. Dr. John Herrick, Extension Veterinarian at the ISU College of Veterinary Medicine, and Dr. Harold Amstutz of the American Association of Bovine Practitioners were instrumental in developing the preconditioning program and coordinating the delivery of the program with Cliff Iverson, Area Extension Livestock Specialist, and co-workers in southeast Iowa. Today, Iowa leads the nation in the size and scope of this program.


The Impact Of Prrs On The Pig Cost Of Production, Colin D. Johnson, John W. Mabry, James B. Kliebenstein, Eric Neumann Jan 2005

The Impact Of Prrs On The Pig Cost Of Production, Colin D. Johnson, John W. Mabry, James B. Kliebenstein, Eric Neumann

Animal Industry Report

Porcine Reproductive and Respiratory Syndrome (PRRS) has had a significant impact on the profitability of swine production. As a means to quantify the financial impact of PRRS to the U.S. swine industry, a study was conducted. This study utilized case studies and a Delphi survey to identify the various impacts PRRS has on farms. Results suggest that impacts to individual farms vary greatly but aggregated data for approximately 100 million market swine being sold each year in the U.S., estimates PRRS adds somewhere between $5.60 and $7.62 to the cost per head sold.


Investment In The Stock Market And Value-Added Agricultural Businesses As Portfolio Investment Alternatives To Farm Expansion, Joshua David Roe Jan 2005

Investment In The Stock Market And Value-Added Agricultural Businesses As Portfolio Investment Alternatives To Farm Expansion, Joshua David Roe

Retrospective Theses and Dissertations

In the past decade, farmers have increasingly invested in value-added agriculture. Analysis of these investments compared to farm expansion by farmers was conducted from a portfolio optimization standpoint. Farms with similar investment patterns were identified by cluster analysis. When individual farm characteristics were analyzed to determine how these attributes affected investment choices, clear influences were found. In general, value-added agricultural investments were found to be an efficient investment alternative to farm expansion. Because of their larger risk, stock market investments play a smaller role in an optimized producer portfolio.

Integrating Hunting And Grazing—A Southern Iowa Investigation Into Management Issues, James L. Pease, Dan Otto, John D. Lawrence Jan 2005

Integrating Hunting And Grazing—A Southern Iowa Investigation Into Management Issues, James L. Pease, Dan Otto, John D. Lawrence

Leopold Center Completed Grant Reports

If successful, land owners that want the habitat can rent the land to cattle producers (increasing access to pasture) without sacrificing their objective (good hunting), and cattle producers can provide good hunting without sacrificing their objective (good pastures). This dual purpose use for land can increase access income for both parties. The key is that the management of such lands must be timed carefully, and managed with both the birds and the cattle in mind. It takes more management skill, but it means the two can be compatible.

Three Essays On Rural Economic Growth , Georgeanne Michael Artz Jan 2005

Three Essays On Rural Economic Growth , Georgeanne Michael Artz

Retrospective Theses and Dissertations

This dissertation is a collection of three papers, each analyzing a particular issue related to economic growth in rural America. The first paper explores the problem of defining rural and the implications for measuring rural growth. It discusses the sample selection problem inherent in using classification methods based on population that change over time. Fast growing rural areas grow out of their rural status, so using the most recent definition of rural in an analysis of growth excludes the most successful places. The findings demonstrate that average economic performance of the areas remaining rural significantly understates the true performance of ...


Three Essays On The Economics Of Innovation , Harun Bulut Jan 2005

Three Essays On The Economics Of Innovation , Harun Bulut

Retrospective Theses and Dissertations

We have identified three specific problems in the economics of innovation and addressed each of them in separate essays in this thesis.;Essay 1 revisits the problem of inefficient diversification efforts of firms in a R&D race setting (Dasgupta and Maskin, 1987)1 by taking into account the fact that firms have the option of trade secrecy in addition to patents in protecting their inventions. This essay is theoretical in nature as we use a game-theoretic modeling of firms' project and IP choices in a R&D race. We find that the availability of multiple IPR protection instruments can move the paths chosen by firms engaged in a R&D race towards the social optimum.;Essay 2 refers to the adoption and diffusion stages of the innovation process as we look at the economic effects of the introduction of Genetically Modified (GM) food in the European Union (EU) agricultural and food system. We develop a partial equilibrium modeling of European agro food sector and calibrate the model's parameters by using the EU data in year 2000. We find ...


Essays On International Trade, Endogenous Quality And Invasive Species Risk , Anh Thuy Tu Jan 2005

Essays On International Trade, Endogenous Quality And Invasive Species Risk , Anh Thuy Tu

Retrospective Theses and Dissertations

This dissertation studies the relation between international trade and two issues that have become the active fields of economic research: the firms' quality decisions and the invasive species risk.;On the quality choice, the dissertation focuses on the impact of Voluntary Import Expansions (VIEs) on firms' quality decisions. I model a vertically differentiated international duopoly, with one firm in each country. A domestic and an exporting firm choose the quality of their goods and then compete in the domestic market. Both quantity and price conjectures are considered. The paper investigates the case where the government of the exporting country imposes ...
