A Forecasting-Programming Method For Swine Production-Marketing Decisions, Larry Janssen, James B. Hassler Oct 1981

A Forecasting-Programming Method For Swine Production-Marketing Decisions, Larry Janssen, James B. Hassler

Nebraska Agricultural Experiment Station: Historical Research Bulletins

This study reports on the development and progress of a forecasting-programming model for swine inventory management and marketing decisions. This model considers interrelationships between breeding herd, feeder pig and finishing hog activities. Objectives were: 1. To structure a dynamic operational decision model for a modern farrow-to-finish swine confinement unit which conforms with economic theory, uses price and cost forecast information and is as consistent as possible with current production scheduling practices. 2. To use and test this model during a combined production and marketing decision process and to compare economic results with results of a standard strategy.

Tb102: A Markov Analysis Of Structural Change And Output Prediction In The New England Egg Industry, Steven P. Skinner Jul 1981

Tb102: A Markov Analysis Of Structural Change And Output Prediction In The New England Egg Industry, Steven P. Skinner

Technical Bulletins

The purpose of this study is to examine changes in the size distribution of egg farms as a Markov process in the three-state region consisting of Connecticut, Massachusetts, and New Hampshire. In 1978 these three states together received cash receipts of 83 million dollars from egg sales. In addition to examining the size distribution of farms, the occurrence of a marked structural change in the egg industry during the period 1967 to 1978 is statistically tested. Also, the future size distribution of egg farms, total number of layers, and egg output are projected.


Wentworth Cooperative Terminal, Inc. Feasibility Analysis, Charles Lamberton May 1981

Wentworth Cooperative Terminal, Inc. Feasibility Analysis, Charles Lamberton

Economics Research Reports

Four local cooperatives have agreed to purchase the elevator at Wentworth, South Dakota, and form a federated cooperative at Wentworth. The Wentworth facility consists of two separate elevators. The main elevator is located on the former Milwaukee Road branchline from Sioux Falls Junction to Madison. The elevator and two annexes have a capacity of approximately 120,000 bushels. A warehouse and frame quonset add approximately 150,000 bushels of storage capacity. A separate office building and truck scale are at the site. The west elevator is a smaller facility with about 53,000 bushels of storage capacity. It is located threeblockswest of the …


An Interregional Study Of Kenya's Livestock Sector Using Linear Programming, Zakayo Joseph Mwangi May 1981

An Interregional Study Of Kenya's Livestock Sector Using Linear Programming, Zakayo Joseph Mwangi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The major purpose of this study was to determine the least-cost method of producing red meat in Kenya. Linear programming was used in the study. A simulated reduction of grazing land available in one of the settlement areas was carried out to indicate what effect this had on the overall regional production pattern of meat in the country.

Kenya was divided into eleven livestock producing and consuming regions. 1979 was used as the base year, and the demand projection was based on the 1979 population. Input and output coefficients, livestock unit requirements, and market prices were developed. A linear programming …


Location Value Of Milk, Martin K. Beutler May 1981

Location Value Of Milk, Martin K. Beutler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Due to the growth of milk marketing areas in the Intermountain West, a study was made to determine the most advantageous allocation of producer milk to twelve selected processing demand areas and to calculate location differentials between these same markets. A theoretical determination of location differentials and of the allocation of milk supply areas to processing centers were made using supply-push and demand-pull price alignment models developed by Associated Milk Producers, Inc., for the months of November 1979 and June 1980. Grade A producer mil k from the six member cooperatives of Western Dairymen' s Cooperative, Inc., was used in …


An Economic Analysis Of Farm Flock Sheep Production In Utah, Ken Beck May 1981

An Economic Analysis Of Farm Flock Sheep Production In Utah, Ken Beck

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to evaluate the economic aspects of farm flock sheep production in Utah. Using 1979 as a base year, costs and returns were calculated from data obtained from twenty- six Utah farms. Characteristics that typify the states· farm flock sheep production, at this writing, with regard to: 1) the farm flock producers and 2) the farm flock enterprise, were presented.

Various models were dev eloped and examined using Multiple Regression and Linear Programming analytical techniques. Multiple Regression was us ed to estimate the effects that different variables had on the profitability of the sheep enterprise. …


The Economic Impact Of Potential Changes In Federal Grazing Policies On Ranchers In Wayne County, Utah, Kib Elden Jacobson May 1981

The Economic Impact Of Potential Changes In Federal Grazing Policies On Ranchers In Wayne County, Utah, Kib Elden Jacobson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to select an area in Utah that was predominantly livestock oriented which used federal lands for livestock grazing, and to develop model ranches exemplifying the typical live-stock operation in the area. These model ranches were then used in a Budget Generator Program (BG) and a Linear Programming framework (LP) to simulate reductions of 25%, 50%, 75% and 100% reductions of BLM land usage. The results were then used to determine income changes, herd size changes, and resource usage in the models as the reductions took place.

The area chosen was Wayne County, Utah because …


An Economic Analysis Of The Akkar Plain Project, E. Douglas Chard May 1981

An Economic Analysis Of The Akkar Plain Project, E. Douglas Chard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this paper is to determine the economic feasibility of the Akkar Plain Agricultural Development Project. Data were collected at representative villages throughout the Akkar Plain in Syria. The data were used to establish the economic setting at the present time on the Akkar Plain and to establish a basis for determining the economic justification for the future planned developments. Methodology used was a farm budget analysis of a before development and after development situation. Internal rate of return and benefit/cost ratio were the measures used to determine economic feasibility. The paper discusses previous work completed, the development …

Biosystems and Agricultural Engineering Faculty Publications

A computer model has been developed to analyze alternate management strategies and energy and economic constraints. Daily production of beef animals and growing crops is simulated in response to prevailing conditions and system interactions using the GASP IV simulation language. Complete inventories of plant dry matter, animal status, production resources and economic net worth are maintained over the simulation period.
