Growth And Survival Of Nebraska Panhandle Wheat Farms Under Selected Financial Conditions, Larry J. Held, Glenn A. Helmers

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Simulation was used to analyze impact of land expansion alternatives, self-imposed borrowing limits, starting equity conditions, and land appreciation upon a firm concurrently seeking growth and survival over a projected 15-year period (1976-1990). An average-sized 960-acre (389 ha) Nebraska Panhandle wheat-fallow farm served as the representative firm. Standard production practices and technologies were used for computing costs. Machinery and operating costs were assumed to inflate five percent annually. Dryland wheat acreage was valued at $375 per acre ($926.63 per ha) in 1976 and was allowed to appreciate at an annual rate of four percent. A hypothetical series of three cyclical …

The Beef Delivery System: Optimal Plant Sizes, Locations And Product Flows, J. C. Hafer, J. G. Kendrick

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The United States beef delivery system is composed of three stages: procurement, processing, and distribution. Minimization of costs associated with these stages can be accomplished best by identification of optimal plant sizes and locations. Research was directed toward an analytical approach that could be used to minimize total costs of the U.S. beef delivery system. This report will discuss the grid system used to divide the · United States into study units, describe features of the model used, discuss research results, and offer conclusions.

Optimal Regional Conjunctive Water Management, Jay E. Noel, Delworth B. Gardner, Charles V. Moore

Agribusiness

An optimal control model is used to determine the socially optimal spatial and temporal allocation of groundwater and surface water among agricultural and urban uses. The control model is described briefly and its advantages over other dynamic models are enumerated. Optimal rates of groundwater pumpage over the planning horizon were highly sensitive to increasing energy costs. Groundwater basins are shown to react differently to alternative economic and hydrological parameters. In a dynamic setting, a policy of pump taxes was shown empirically to be superior to pro-rata quotas and uncontrolled pumpage.

Sb 545. Costs Of Distributing Dry·Bulk Fertilizer--Effects Of Plant Size, Plant Utilization, Use Density, And Method Of Delivery And Application, Dale G. Anderson, James Miller

Department of Agricultural Economics: Faculty Publications

1. About 1.8 million tons (1.6 million t) of fertilizer were applied by ~ ebraska farmers in 1978, an increase of nearly 800 percent over 1954 levels. Slightly more than one-third of recent usage was dry-bulk fertilizer.

2. Utilization of plant capacity was the most important of the cost factors analyzed. Even at capacity output, average fixed costs accounted for half to two-thirds of average total costs. Increasing plant output from 50 percent to 100 percent of capacity saved from $12.23 to $17.01 per ton ($13.48 to $18.75/t), depending on plant size and type of application/delivery system.

3. Economies of …

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 …

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 Involvement Of The Farm Animal Veterinarian In Animal Welfare, David G. Llewellyn

Veterinary Science and Medicine Collection

The farm animal practitioner has always played a dual role. The primary role is humanitarian, concerned with the well-being of the livestock, and the secondary role relates to the economics of the enterprise.

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.

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.

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 …

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 …
