The Relative Importance Of Competencies Needed By Industrial Energy Managers From The Larger Manufacturers In Iowa, Timothy J. Eibes Jul 1983

The Relative Importance Of Competencies Needed By Industrial Energy Managers From The Larger Manufacturers In Iowa, Timothy J. Eibes

Graduate Research Papers

The importance of identifying the competencies needed by energy managers is reflected in the seriousness of the energy problem and the impact it has on the industrial setting. The newness and ambiguity of EM, coupled with the increasing importance of the concept, add to the need for identifying the necessary competencies required in managing energy.

Ideally, once these competencies are identified, they should be the focus of those educational curriculums designed to produce energy managers. Currently there are only 25 post-high school institutions in the U.S. that have energy management curriculums (The College Blue Book, 1981). Less than half of …


Psychological Aspects Of Slaughter: Reactions Of College Students To Killing And Butchering Cattle And Hogs, Harold A. Herzog Jr., Sandy Mcgee Jan 1983

Psychological Aspects Of Slaughter: Reactions Of College Students To Killing And Butchering Cattle And Hogs, Harold A. Herzog Jr., Sandy Mcgee

Human Health Collection

This study examined the reactions of college students involved in slaughtering cattle and hogs as part of their jobs on a college work crew. The 27 students were surveyed on attitudes containing items toward slaughtering animals and toward different uses of animals. Nineteen were later interviewed. Some aspects of slaughtering were reported to be more bothersome than others. There was a relationship between the amount of experience of the subjects in slaughtering and also their general attitudes toward various uses of animals and their responses to several of the items on the questionnaire. The perceived benefits of the slaughtering experience …


Ethologic And Economic Examination Of Aviary Housing For Commercial Laying Flocks, D. W. Fölsch, Chr. Dolf, H. Ehrbar, T. Bleuler, H. Teijgeler Jan 1983

Ethologic And Economic Examination Of Aviary Housing For Commercial Laying Flocks, D. W. Fölsch, Chr. Dolf, H. Ehrbar, T. Bleuler, H. Teijgeler

Agribusiness Collection

The result of our work shows that appropriate housing is necessary for intensively kept hens and that the housing has to correspond to the vital needs and the nature of the animals.

This is important for two reasons: a) the innate needs of the birds must be satisfied; b) for the proper development of the animal and successful egg production.

The housing facilities should allow the following functional cycles without restrictions:

Social organization: the structuring of a group or unit of animals.

Locomotion: walking, running, fluttering, flying.

Feeding behavior: search for food and water, food and water pecking, ground scratching, …


No Need To Be Boxed In: Group Pens And Grain For Veal Calves, Michael S. Mosner Jan 1982

No Need To Be Boxed In: Group Pens And Grain For Veal Calves, Michael S. Mosner

Agribusiness Collection

My family has been in the wholesale veal business for 30 years. The basis of this business has been various breeds of female beef calves that are slaughtered at less than 500 lb. These calves are allowed to suck from cows and graze until they are ready for market. Beef calves, however, tend to vary in quality and quantity depending on the tjme of the year that they are purchased and raised. Generally, calves become scarce in the spring, when feeders are buying calves to put out on pasture. Then, in the summer and fall, large numbers of calves usually …


Euthanasia Of Day-Old Male Chicks In The Poultry Industry, Walter Jaksch Jan 1981

Euthanasia Of Day-Old Male Chicks In The Poultry Industry, Walter Jaksch

Agribusiness Collection

Humane killing of animals implies a painless death (euthanasia). This depends on the rapidity with which unconsciousness is achieved and the maintenance of this state until death occurs. Euthanasia methods for day-old chicks must also be economical and should not interfere with the use of the carcasses for animal food or fertilizer. Manual decapitation or dislocation of the neck are the best available manual methods of euthanasia. For larger numbers of birds, the literature recommends homogenization in a crusher. In the author's own experiments, the destruction of day-old chicks was most effectively carried out by poisoning with carbon dioxide (CO …


One Answer To The Confinement Pig Problem, Arthur Nehring Jan 1981

One Answer To The Confinement Pig Problem, Arthur Nehring

Human Health Collection

A new design for an intensive hog finishing operation is presented. The "maze deconfinement" system consists of a series of 4-walled concrete pens arranged in a T-maze within a confinement building that is designed to utilize solar energy. In addition to low cost and efficient use of energy, the system has the following advantages: higher feed conversion rate; less fighting among and injuries to hogs; some freedom for hogs to exercise and explore; decreased labor. The system has been in use on the author's farm since the end of 1976.

Behavior And Weight Loss Of Feeder Calves In A Railcar Modified For Feeding And Watering In Transit, T. H. Friend, M. R. Irwin, A. J. Sharp, B. H. Ashby, G. B. Thompson, W. A. Bailey

Agribusiness Collection

The behavior of 164kg Angus and Hereford calves was studied in a double deck 26m x 2.6m "jumbo" railcar equipped with feed and water. A 4,180 liter water tank positioned in the center of each deck divided the car into four compartments. Fifty head were loaded into the lower and upper forward compartment (252kg/m2floor space], each containing 675kg of hay in racks. The two rear compartments served as quarters for equipment and researchers. Two video cameras were mounted in the upper forward compartment containing calves. Behavior of the calves was monitored, with portions video taped during rail transport …


Livestock Behavior As Related To Handling Facilities Design, Temple Grandin Jan 1980

Livestock Behavior As Related To Handling Facilities Design, Temple Grandin

Agribusiness Collection

A knowledge of the behavior of different species of livestock as well as different breeds within a particular species is essential to the proper planning of a handling facility. An optimal facility should incorporate features which minimize stress on the animal and maximize the efficiency of movement from holding pen to slaughter area. Handler awareness of the animals' perception of critical distance flight zone and personal space requirements also reduces problems with balking and alarm behavior. Many improvements can be made with relative ease, thus enabling already existing facilities to upgrade their operations.


Bruises And Carcass Damage, Temple Grandin Jan 1980

Bruises And Carcass Damage, Temple Grandin

Agribusiness Collection

Bruising and carcass damage is a major source of financial loss to slaughterhouses in the United States, approximately $46 million per annum. The absence of easily administered tests to determine where and/or when bruising occurs results in the slaughter plant absorbing carcass damage costs. Rough, abusive handling of livestock accounts for over half of all bruising. Injuries occur through overuse of persuaders, careless transport methods, and faulty equipment. Other elements relevant to carcass loss include branding cattle, abscesses, spreader and crippling injuries, sickness and death during extreme weather conditions, and carcass shrink. The 1979 regulations under the Humane Methods of …


Designs And Specifications For Livestock Handling Equipment In Slaughter Plants, Temple Grandin Jan 1980

Designs And Specifications For Livestock Handling Equipment In Slaughter Plants, Temple Grandin

Agribusiness Collection

Properly designed, maintained and operated livestock handling facilities are more humane and more efficient in ensuring a steady uninterrupted flow of livestock to the slaughter line, and will usually pay for themselves by reducing bruises, injuries and lost work time. Down time or lost work time in a large slaughter plant is expensive since a five minute delay can cost over $500 in lost meat production. Another benefit of good systems is increased safety for the employees; many serious accidents have occurred when agitated cattle turn and trample a handler.

Although specific recommendations vary for different species, certain general principles …


Mechanical, Electrical And Anesthetic Stunning Methods For Livestock, Temple Grandin Jan 1980

Mechanical, Electrical And Anesthetic Stunning Methods For Livestock, Temple Grandin

Agribusiness Collection

A good stunning method must render an animal unable to experience pain and sensation prior to hoisting and slaughter. The three basic types of stunning methods which are classified as being humane (i.e., painless) in the United States, Europe and other foreign countries are captive bolt (penetrating and nonpenetrating), electrical, and C02 (carbon dioxide) gas anesthesia.

The physiological mechanisms of stress are the same before and after the onset of unconsciousness. The release of epinephrine as a result of stress inducers has an effect on the quality of the meat and it is therefore desirable to use a stunning method …


The Effect Of Stress On Livestock And Meat Quality Prior To And During Slaughter, Temple Grandin Jan 1980

The Effect Of Stress On Livestock And Meat Quality Prior To And During Slaughter, Temple Grandin

Agribusiness Collection

The effects of stress on cattle, pigs and sheep prior to slaughter are reviewed. Long-term preslaughter stress, such as fighting, cold weather, fasting and transit, which occurs 12 to 48 hours prior to slaughter depletes muscle glycogen, resulting in meat which has a higher pH, darker color, and is drier. Short-term acute stress, such as excitement or fighting immediately prior to slaughter, produced lactic acid from the breakdown of glycogen. This results in meat which has a lower pH, lighter color, reduced water binding capacity, and is possibly tougher. Psychological stressors, such as excitement and fighting, will often have a …


Problems With Kosher Slaughter, Temple Grandin Jan 1980

Problems With Kosher Slaughter, Temple Grandin

Agribusiness Collection

Ritual slaughter to produce kosher meat is rooted in the teachings and writings of the Talmud. However, the preslaughter handling features of modern systems, particularly the shackling and hoisting of large steers, contravene the basic message of humaneness included in the teachings. The throat-cutting of a live, conscious animal is relatively pain-free, provided that certain precautions are followed, but U.S. kosher plants need to install newly developed conveyor-restrainer systems to eliminate the abuses of shackling and hoisting. Conveyor-restrainer systems for large and small animals are discussed.


Grain Transportation Problems In Nebraska: Causes And Cures [Proceedings Of The Nebraska Grain Transportation Seminar], Dale G. Anderson, Dean Linsenmeyer, Michael S. Turner Dec 1979

Grain Transportation Problems In Nebraska: Causes And Cures [Proceedings Of The Nebraska Grain Transportation Seminar], Dale G. Anderson, Dean Linsenmeyer, Michael S. Turner

Department of Agricultural Economics: Faculty Publications

The Nebraska feed grain and soybean harvest of 1979 was one which will not soon be forgotten by those who participated in its production and marketing. Yields and production broke all previous records. Record export demands for the crop placed record service requirements on transportation and handling systems. Record movements of grain from farms to elevators and to inland and export terminals were reported. At the same time, complaints of inadequate capacity to store and transport the grain were perhaps also of all-time record proportions. Corn and milo accumulated in open piles on farms and at country collection points. Problems …

Economic Impact Of Railroad Branch-Line Abandonments: Results Of A Southcentral Nebraska Case Study, Dale G. Anderson, Floyd D. Gaibler, Mary Berglund Sep 1976

Economic Impact Of Railroad Branch-Line Abandonments: Results Of A Southcentral Nebraska Case Study, Dale G. Anderson, Floyd D. Gaibler, Mary Berglund

Department of Agricultural Economics: Faculty Publications

Some 249 miles of Nebraska rail line have been abandoned since 1963; another 310 miles are in contention at abandonment proceedings. The abandonment of these and other lines could have serious economic implications for grain elevators, farmers, and rural communities.

Track abandonment is occurring during a time of rapid expansion in the grain industry. U. S. corn and grain sorghum production increased more than 40 percent during the decade ending in 1973. Exports of these commodities increased 157 percent during the same period. Increases in grain production and exports, along with a shorter harvest season, are placing great strains on …

The Effect Of Straw On The Behaviour Of Sows In Tether Stalls, D. Fraser Aug 1975

The Effect Of Straw On The Behaviour Of Sows In Tether Stalls, D. Fraser

Housing and Confinement of Farm Animals Collection

The behaviour of sows in tether stalls with and without straw was studied in two experiments. Sows lay down more when 1 kg of straw was provided daily, especially when it was chopped and mixed wet with the food (dietary effect). Sows without straw performed a variety of stereotyped oral and other activities which were greatly reduced by the provision of loose straw that could be chewed and manipulated throughout the day (recreational effect). Sows were frequently seen standing or sitting motionless with the head drooping, probably in a state of drowsiness. This behaviour was virtually eliminated by full straw …

The Consideration Of Transportation Costs In The Study Of Customs Unions, Joseph Michael Edmonds Jan 1972

The Consideration Of Transportation Costs In The Study Of Customs Unions, Joseph Michael Edmonds

Theses, Dissertations and Capstones

A customs union is a movement toward economic integration which can be defined, in an absolute sense, as complete factor-price equalization. A customs union consists of a group of countries which have abolished all tariffs between themselves; but maintain an equal; arbitrated tariff among the countries of the outside world. A customs union is only one of several types of organizations which allow discrimination against the excluded countries. These trade groups can be differentiated by the degree of economic integration among its members and their policy toward the rest of world countries, the countries excluded from the trade organization.


Analysis And Prediction Of Telephone Demand In Local Geographic Areas, Douglas M. Dunn, William (Bill) H. Williams, W. Allen Spivey Oct 1971

Analysis And Prediction Of Telephone Demand In Local Geographic Areas, Douglas M. Dunn, William (Bill) H. Williams, W. Allen Spivey

Publications and Research

An approach to forecasting the demand or local area telephone service is presented in this paper. The specific problem discussed is the fore­ casting of main stations in three Michigan metropolitan areas. Several different statistical models are used. The first class of models introduced uses adaptive exponential smoothing and is based solely on the past history of the time series involved. Although appropriate data at the local area level are very difficult to obtain, two exogenous time series related to household formations are used to construct more elaborate models for one of the areas. The various models are evaluated by …

An Investigation Of The Perceived Leadership Behavior Of First-Line Supervisors In Selected Manufacturing Plants, Robert Edward Holmes Jan 1971

An Investigation Of The Perceived Leadership Behavior Of First-Line Supervisors In Selected Manufacturing Plants, Robert Edward Holmes

Graduate Theses and Dissertations

The first-line supervisor appears to be caught in a dilemma between the demands of his superior and the needs of his subordinates. This study focuses on the dilemma by describing and analyzing the leadership behavior of most and least effective first-line supervisors as perceived by superiors, subordinates, and by the supervisors themselves.

Two basic dimensions of leadership behavior, power-structure and consideration-sensitivity, were investigated by using a leadership rating questionnaire. Participating plants, listed in the Directory of Arkansas Industries, were twenty-three small manufacturers employing five or more production supervisors and 100 to 500 production workers. Participants in each plant were the …


Mp25 The Problem Of Freight Car Supply, John Richard Felton Aug 1970

Mp25 The Problem Of Freight Car Supply, John Richard Felton

Department of Agricultural Economics: Faculty Publications

As early as 1907 the Interstate Commerce Commission held extensive hearings on freight car shortages. At frequent intervals ever since, Congress and the commission have addressed themselves to the problem of freight car supply with considerable vigor but meager results. Allegations of an inadequate supply of freight cars have been widespread in recent years. The decline in the number of freight cars is easy to document: between 1959 and 1968, the number of cars used in grain transport (boxcars and covered hopper cars) declined by 26%. If, however, consideration is given to changes in car capacity and car miles …


Recent Senior Appointments In The Department Of Agriculture/ Pioneer Adviser Retires As Chief Of Wheat And Sheep Division, Department Of Agriculture, Western Australia Jan 1970

Recent Senior Appointments In The Department Of Agriculture/ Pioneer Adviser Retires As Chief Of Wheat And Sheep Division, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

THE Department of Agriculture moves into the 1970s with many of its senior positions filled by officers appointed within the last few months of 1969. The new men replace personalities who have for many years dominated the agricultural scene in Western Australia—pioneers of scientific agriculture who, in their many years of service with the Department, helped to establish prosperous farming industries in many parts of the State. Later they were largely responsible for the tremendous agricultural development that took place from 1946 to 1969.

One of the Department of Agriculture's best known agricultural advisers was Mr. A. S. Wild, who …
