The Economic Feasibility Of Confinement Feedlots And The Analysis Of Seasonal Marketing Variations For Feeder Cattle In South Dakota, Daniel W. Francke
The Economic Feasibility Of Confinement Feedlots And The Analysis Of Seasonal Marketing Variations For Feeder Cattle In South Dakota, Daniel W. Francke
Electronic Theses and Dissertations
South Dakota apparently produces an adequate quantity of feeders and feed grains to substantially increase slaughter cattle production. Furthermore, South Dakota prices for feed grain, roughage, and feeder cattle are equal to, or less than, the prices for these inputs in other areas where cattle feeding has flourished in recent years. It should also be determined how South Dakota farmers might increase fat cattle production. Therefore, in an attempt to explain South Dakota's slow cattle feeding growth and possibly help farmers in South Dakota and neighboring areas develop the cattle feeding industry, the following problems were researched. First, this area …

Minnesota Avenue, a commercially zoned strip in Sioux Falls, South Dakota, referred to as an urban arterial by the City Planning Office of major arterial by Harlan Bartholomew and Associates, constitutes the study area. We are concerned in this study with a narrow (eighty feet of right of way, twenty-seven city blocks long) piece of public land and its contact with both private and public parcels of property. Minnesota Avenue in its entirety extends from South Dakota Highway 38 on the north through the approximate center of the city of Sioux Falls joining Interstate 229, a circumferential route on the …
The Effect Of Market Weight And Ration Concentrate Level On Carcass Traits Of Bulls, Heifers And Steers, Peter B. Smith
The Effect Of Market Weight And Ration Concentrate Level On Carcass Traits Of Bulls, Heifers And Steers, Peter B. Smith
Electronic Theses and Dissertations
Increasing worldwide demand for animal protein, growing pressure on the available cereal grains by a multiplying world population and greater availability of United States agricultural products worldwide make it imperative that beef volume and production efficiency increase. Consumer demand for a lean, high quality, trim product dictates production of rapid growing, efficient beef animals with minimum fat deposition at market weights. In the face of increasing demand, governmental constraints in the form of economic controls, ecological considerations and restrictions in the use of antibiotics and growth promoting agents force the beef industry to examine and improve production efficiency. Currently, packers …

Dried Whey As An Additive For Alfalfa Haylage And As A Grain Supplement For Dairy Cows, Sitakantha Dash
Dried Whey As An Additive For Alfalfa Haylage And As A Grain Supplement For Dairy Cows, Sitakantha Dash
Electronic Theses and Dissertations
This research was conducted to explore the possibility of utilizing surplus whey in dairy cattle rations. Four experiments determined the influence of whey on preservation, digestibility and feeding value of alfalfa haylage. The last experiment was initiated to evaluate dried whey as a grain supplement. When dried whole whey was added at O, 1, and 10% levels to reconstituted alfalfa haylage (chopped baled hay plus 50% water) and preserved in sealed metal containers, it reduced pH, decreased acetic acid, and increased lactic acid. The general pattern of fermentation was better in whey-treated haylages than in corresponding untreated haylages. An in …
Seasonal Movements And Habitat Selection Of Pheasant Cocks In South Dakota, Robert A. Fedeler
Seasonal Movements And Habitat Selection Of Pheasant Cocks In South Dakota, Robert A. Fedeler
Electronic Theses and Dissertations
Data were gathered on seasonal movements and habitat selection of 30 pheasant (Phasianus colchicus) cocks that were radio-equipped in eastern South Dakota from 1970 to 1972. Pheasant cocks stayed in an area of less than 100 acres from spring through hunting season. In winter, cocks used even smaller areas more intensively. Cocks moved about their home range by shifting their activity center rather than by adjustment in range of daily travel. Adult cocks seemed to have strong site attachments on a year-round basis. Immature cocks were more mobile, especially during the fall prior to hunting season. In spring, adult cocks …

Partial Characterization Of Animal Growth Inhibitors From Soybeans, Joseph Richard Uckert
Electronic Theses and Dissertations
The pH 4. 4 supernatant from raw (unheated) soybean meal was separated into 5 fractions on a Sephadex G-25 column in efforts to isolate the animal growth inhibitors present soybeans. Each fraction was added to the diet of growing mice and growth inhibition (GI) activity was determined by comparing their_ growth rates to g1"'owth rates achieved on an autoclaved soybean meal diet. Fractions I and II each contained about 50% of the GI activity, with a trace in fraction III and none in fractions IV and V. Only fraction I contained trypsin inhibitor and caused pancreatic enlargement. Fraction I was …
The Vitamin E Status Of Lactating Dairy Cows After Receiving Stored Feeds For 15 Months, Marc Dellhime Eckhart
The Vitamin E Status Of Lactating Dairy Cows After Receiving Stored Feeds For 15 Months, Marc Dellhime Eckhart
Electronic Theses and Dissertations
The trend in dairying in recent years has been towards more confinement housing and higher producing animals. Such confinement housing often leads to year-around feeding of stored feeds, such as silage, haylage, and hay with no pasture grazing or feeding of freshly cut forages. Since stored feeds contain substantially less vitamin E than those same forage when freshly cut or grazed, it may be important to re-evaluate the vitamin E status of cows fed stored feeds continuously. The requirement of cattle for vitamin E are largely unknown. The one study involving adult cattle, conducted 25 years ago, found that 1.82 …
Groundwater Quality Variation In The Vicinity Of Dying Terraces Designed To Dispose Of Runoff From A Cattle Feedlot, Thomas Burton Andersen
Groundwater Quality Variation In The Vicinity Of Dying Terraces Designed To Dispose Of Runoff From A Cattle Feedlot, Thomas Burton Andersen
Electronic Theses and Dissertations
Much attention has been focused on protecting surface bodies of water from human and animal sources of pollution. In states similar to South Dakota, animal pollutants, may be potentially a much greater hazard to surface waters than are human sources of pollutants. For the preceding reason much consideration has been directed towards methods to control pollution from animal sources. The cattle feedlot is considered by some as one of the largest reservoirs for contaminants able to reach surface bodies of waters. A feedlot can be generally described as an enclosed area where cattle are concentrated for the purpose of preslaughter …
The Effects Of Livestock Waste On Some Soil Strength Characteristics And Selected Tillage Operations, Rodney Joseph Devine
The Effects Of Livestock Waste On Some Soil Strength Characteristics And Selected Tillage Operations, Rodney Joseph Devine
Electronic Theses and Dissertations
Livestock waste is becoming a problem in the area of pollution. About 2 billion tons of animal waste are produced each year in this country. Many farmyards and feedlots have allowed the waste to be washed into nearby streams, polluting them. Large commercial livestock feeding operations have such a large amount of waste causing pollution that steps have been taken by the government to keep large scale feedlots from becoming pollution hazards. Many of these methods of use and disposal are in the development stage. However, livestock wastes cannot be allowed to accumulate while new methods are being developed. The …
Ridge Vent Influence On Airflow Characteristics In A Model Open Front Beef Confinement Building, Donald P. Froehlich
Ridge Vent Influence On Airflow Characteristics In A Model Open Front Beef Confinement Building, Donald P. Froehlich
Electronic Theses and Dissertations
Continued and increased use of confinement methods for fattening beef cattle in South Dakota _are inevitable for many· reasons: surface runoff from feedlots is practically eliminated, the cost and labor required for bedding are decreased, problems with adverse surface conditions and manure accumulation are reduced, diseases are usually decreased, and national and worldwide demands for red meat are augmenting. When animal densities are increased maximum utilization can be made of the labor saving devices obtainable with increased capitalization. However, as animal densities increase environmental maintenance within a confinement structure becomes an increasingly important design consideration. Therefore, accurate and pertinent information …
Effects Of Mimosine On Various Reactions Of Amino Acids, Liang-Rong Hwang
Effects Of Mimosine On Various Reactions Of Amino Acids, Liang-Rong Hwang
Electronic Theses and Dissertations
Mimosine{Leucaenol, Leucaenine); beta-N-(3-hydroxy-4- pyridone)-a1pha-amino propionic acid is one of the free amino acids found in the seeds and leaves of the Leucaena glauce benth and related tropical plants. This legume which is. also called "Jumbie Bean”, "Lamtoro" and "Koa Haole" is drought resistant, grows in poor soil, and has a higher protein content than alfalfa. It would be excellent feed for animals if it were not for the toxic effects of the mimosine in it. It was Morris who first reported in 1897 the toxic effects of mimosine for animals ingesting mimosine showed symptoms of hair loss, infertility, retardation of …

Implications Of Pathogenicity And Transplacental Passage Of Listeria Monocytogenes L-Forms In Experimentally Infected Mice, Pam R. Kieffer
Electronic Theses and Dissertations
Throughout the past decade, there has been remarkable increase of interest in studies of bacterial L-forms and mycoplasmas. These studies have enriched our understanding of the functions of various components of bacterial cells. Questions of primary interest deal with the probable role of L-forms in recurrent infections and in disease. The purpose of this investigation was to determine the effect of Listeria L-forms on impregnation of mammals. Infection appeared to disturb pregnancy by disruption of implantation of the embryo or by abortion or reabsorption of the embryo. Infection appeared to disturb conception by prevention of implantation of the embryo or …
Irradiation Damage Of The Developing Chick Embryo, With Special Attention To Growth Reduction, Andrew Lee
Irradiation Damage Of The Developing Chick Embryo, With Special Attention To Growth Reduction, Andrew Lee
Electronic Theses and Dissertations
The impact of radiation on man has become increasingly important in recent years. Since humans cannot be used as experimental subjects, the experimental work with radiation must be conducted with other species. The domestic fowl possesses pertinent advantages which make it desirable for studying some of the aspects of radiation. Chicken embryos can readily be irradiated under various conditions. The relatively short life span of the chicken hastens the acquisition of results and therefore more experiments-may be conducted within a given period of time. Each individual has a relatively low value so that animals may be sacrificed without excessive monetary …
Amino Acid Supplementation Of Opaque-2 Corn For Growing Pigs, Reid V. Merrill
Amino Acid Supplementation Of Opaque-2 Corn For Growing Pigs, Reid V. Merrill
Electronic Theses and Dissertations
Protein needs and amino acid requirements are of major interest in the swine industry today. A considerable amount of research has been conducted on these subjects and more is sure to follow. Amino acid content and balance are now being recognized as more important factors in swine nutrition than total protein alone. Recently, the development of opaque-2 corn with higher amounts of lysine and tryptophan than normal corn has stimulated interest in its presence in simplified diets to supply the amino acid needs of swine. Performance of pigs fed opaque-2 corn has generally been superior to that of pigs fed …
Some Effects Of Dietary Fats Or Copper On Growth And Lipid Composition Of Turkeys And Rats, Richard A. Nelson
Some Effects Of Dietary Fats Or Copper On Growth And Lipid Composition Of Turkeys And Rats, Richard A. Nelson
Electronic Theses and Dissertations
During the past decade there has been a large increase of interest in what causes heart attacks. Heart attacks are claiming the lives of more and more people each year, but the exact cause(s) for this increase have not been found. Some research, however, has shown that high serum cholesterol levels are correlated with arterial plaque formation. Plaque formation has, in turn, been implicated in causing myocardial infarction and reduced blood flow to areas or the heart muscle. This results in ischemia or oxygen deprivation to that area. This condition often results in death of the individual if not …
The Role Of Western Equine Encephalitis And Saint Louis Encephalitis In Mosquitoes And Animals Of South Dakota, Mark Edward Steichen
The Role Of Western Equine Encephalitis And Saint Louis Encephalitis In Mosquitoes And Animals Of South Dakota, Mark Edward Steichen
Electronic Theses and Dissertations
The World Health Organization defines an arbovirus as follows. An arbovirus must produce a viremia in one or more vertebra species, multiply in some arthropod that feeds on viremic blood and be transmitted through feeding. Ticks and mosquitoes are the main arthropod vectors that transmit this virus. The fact that the Missouri Basin states have had the post extensive epidemics of western equine encephalitis (WEE) and St. Louis encephalitis (SLE) in the country makes South Dakota an excellent area for concentrated arbovirus studies. These major environmental changes might alter the biological balance of the complex ecological factors that determine the …
In Vitro Digestibility Of Diallel And Polycross Progenies Of Intermediate Wheatgrass, Ronald Theodore Thaden
In Vitro Digestibility Of Diallel And Polycross Progenies Of Intermediate Wheatgrass, Ronald Theodore Thaden
Electronic Theses and Dissertations
Previous forage plant evaluation by breeders has centered around agronomic factors that determine persistence and forage and seed production with little consideration given to utilization. Forages must be consumed by animals for utilization, so forage quality as it relates to the animal should be an important evaluation factor. Plants and animals function together in determining forage quality. Such plant characters as leafiness, coarseness, height and physiological age are easily observed and deternd.ne quality to a degree. Other components such as digestibility, lignin and protein are just as important, but cannot be determined as easily. Animal acceptance and consumption are also …
