The Determination Of Salmonellae Transmission In Embryonated Chicken Eggs By The Use Of Whole-Body Sagittal Section And Fluorescent Antibody Techniques, Mark Michael Kieffer

Electronic Theses and Dissertations

“Domestic poultry constitutes the largest single reservoir of Salmonella organisms existing in nature,” stated J. E. Williams of the Southeast Poultry Research Laboratory, Athens, Georgia. He reported that the frequency of salmonellae reported in poultry is due to the high population exposed to salmonellae and the extensive programs involved in isolation and identification. The 1971 annual Summary of Salmonella published by the Center for Disease Control, Atlanta, Georgia reports 25,694 cases of salmonellosis in humans. This figure represents an increase of 6.1% over the 24,216 cases reported in 1970, and a 16.6% increase over the 21,413 cases reported in 1969. …

Comparative Study Of Constant Voltage And Constant Current Electroanesthesia, Anand Vithal Tulpule

Electronic Theses and Dissertations

In the field of anesthesia, drugs are used extensively, however; electro anesthesia or the use of electric current to achieve anesthesia is also being studied because of its excellent recovery characteristics. This thesis is a comparative study of different techniques of achieving electro anesthesia. Pharmacologically, general anesthesia is a completely irreversible converging depression of certain central nervous system functions wherein respiration, circulation and the vital life support mechanisms are not seriously impaired. Clinically, general anesthesia is a production of unconsciousness, some degree of areflexia, muscular relaxation and varying degrees of respiratory depression in an orderly progression. Electro anesthesia can be …

The Effects Of Protein Level And Age On Performance, Carcass Characteristics And Nutrient Digestibility Of Growing-Finishing Swine, Tim S. Stahly May 1972

The Effects Of Protein Level And Age On Performance, Carcass Characteristics And Nutrient Digestibility Of Growing-Finishing Swine, Tim S. Stahly

Electronic Theses and Dissertations

The present trends toward the meat type hog and the consumer's demand for lean cuts have resulted in the investigation of methods to produce leaner pigs. During recent years there has been considerable interest in the effect of dietary protein levels on growth rate, feed efficiency and carcass characteristics of swine. Several reports have indicated that increased dietary protein levels may improve growth performance and/or carcass leanness without adversely affecting the quality of the pork produced. However, little research has been conducted to show if this decrease in carcass quality of pigs fed a low protein diet could be at …


Detection And Assay Of Viruses Using Latex Particles, Thomas Charles Sorensen May 1972

Detection And Assay Of Viruses Using Latex Particles, Thomas Charles Sorensen

Electronic Theses and Dissertations

When hemagglutination is caused by the virus particle itself, a particle joins two red blood cells together by forming a bridge between them. If sufficient hemagglutination particles are present, the red cells form clusters of larger aggregates which fall to the bottom of the test tube or well. It is this sort of biophysical phenomenon which is being investigated in this study. Rather than using red blood cells as the adsorbent, to the surface of which the virus adsorbs, some solid adsorbents have been utilized to substitute for the red cells in a variety of experimental manipulations. Bentonite has been …

Influence Of Estrus Synchronization With Mga On Subsequent Ovum Transport And Fertility In Beef Cows, John D. Reed Apr 1972

Influence Of Estrus Synchronization With Mga On Subsequent Ovum Transport And Fertility In Beef Cows, John D. Reed

Electronic Theses and Dissertations

Artificial insemination (A.I.) has been commercially available to beef producers for nearly 20 years. However, most beef cattlemen do not use A.I. because of the labor and management required during the long breeding season. Successful estrus synchronization would allow optimum use of labor and facilities thus allowing maximum use of A.I. It would also enable the producer to more closely control calving dates. Thereby assuring a more uniform group of offspring at market time. More effective use of A.I. would also enhance the use of outstanding performance tested sires and aid in control of certain reproductive diseases. Control of the …

Heat And Moisture Production In A Closed Environment Beef Building During Warm Weather, Martin L. Hellickson

Electronic Theses and Dissertations

The need for improved production facilities is emphasized by the fact that beef consumption is at record levels in the United States with continued growth predicted. The annual per capita consumption of beef and veal in the United States was nearly 73 pounds in 1949 and increased 56 per cent to approximately 114 pounds per person by 1969. The demand for beef is also increasing in developed areas throughout the rest of the world. Increases in demands for beef have stimulated the beef industry to make significant gains in production. The production of beef in the United States has increased …


Production Of Staphylococcal Enterotoxin B In Foods With Varied Environmental Conditions, Robert Jefferey Heidelbauer Apr 1972

Production Of Staphylococcal Enterotoxin B In Foods With Varied Environmental Conditions, Robert Jefferey Heidelbauer

Electronic Theses and Dissertations

The number one cause of food poisoning is enterotoxin produced by certain strains of Staphylococcus aureus. Knowledge of the conditions which inhibit enterotoxin production in foods is of great economic importance. Previous research on staphylococcal food poisoning has been concerned with the presence and growth of Staphylococcus aureus in foods. Until recently, little work has been done with detection of the toxin in foods, even though proof of responsibility for the poisoning depends on direct demonstration of enterotoxin in the food. Before research on enterotoxin production could be feasible a rapid method of detection was needed. Early detection techniques involved …


Properties Of Six South Dakota Bovine Picornaviruses, Janet Marie Mattson Apr 1972

Properties Of Six South Dakota Bovine Picornaviruses, Janet Marie Mattson

Electronic Theses and Dissertations

Since the first enterovirus isolates in 1957 and rhinovirus isolation in 1962, more than 600 isolations of bovine picornaviruses have been reported. Previous workers have been concerned primarily with serological comparisons among their own isolates. Only two viruses, LCR4 and BEV I, are available to investigators for serologic comparison. Picornaviruses have been isolated from animals with. respiratory diseases, diarrhea, and histories of abortions. Interest has not been that great because of the vast number of strains isolated, and at present, the studied strains have no disease attributed to them. Little has been done with these strains of virus except to …

Concentrations of aldrin, DDD, DDE, DDT, dieldrin, endrin, heptachlor, heptachlor epoxide, lindane, methoxychlor and toxaphene were determined by gas chromatography and thin-layer chromatography. DDT and its metabolites, DDD and DDE, were the highest residues detected in all trophic levels examined. Heptachlor, heptachlor epoxide, aldrin, dieldrin and lindane were present in the majority of sample types, while neither endrin nor methoxychlor was detected above analytical confidence limits in any …


Taxonomic Composition, Biomass, And Trophic Structure Of Grassland Invertebrates At Cottonwood, South Dakota, Pauline Estelle Hamm Apr 1972

Taxonomic Composition, Biomass, And Trophic Structure Of Grassland Invertebrates At Cottonwood, South Dakota, Pauline Estelle Hamm

Electronic Theses and Dissertations

This particular study is concerned with invertebrates found on a grassland ecosystem; therefore, most of the literature reviewed was limited to studies involving insects. Since the literature on ecosystems is extensive, only the following trends as listed by Clark et al. were reviewed: physical factor ecology, production ecology, and population ecology. Smith was among the first to emphasize physical factor ecology which stressed the importance of abiotic factors in regulating animal numbers. He first used the terms density-dependent and density independent. Production ecology introduced the study of more complex life communities and considered the trophic association or food-cycles and the …


Effects Of Erythropoietin On Intestinal Iron Absorption In Rabbits, Thomas John Hajek Apr 1972

Effects Of Erythropoietin On Intestinal Iron Absorption In Rabbits, Thomas John Hajek

Electronic Theses and Dissertations

Erythropoietin ls a mammalian hormone synthesized primarily by renal tissues ln response to tissue hypoxia. the hormone accelerates erythropoiesis, the process of red blood cell (erythrocyte) production, Increasing oxygen transport to tissue cells. Accelerated erythropoiesis implies an increased rate of hemoglobin synthesis and, therefore, an increased demand for iron, which ls an integral part of the hemoglobin molecule. Iron, to meet this requirement, may be obtained by mobilizing storage iron or by enhancing dietary iron absorption. That erythropoiesis promotes increased absorption of dietary iron has been delineated. However, the actual mechanism involved has not been elucidated completely. It has been …


Mechanism And Regulation Of Nitrogen Assimilation In Klebsiella Pneuminiae M5al, Ming- Liang Li Apr 1972

Mechanism And Regulation Of Nitrogen Assimilation In Klebsiella Pneuminiae M5al, Ming- Liang Li

Electronic Theses and Dissertations

The pathway of the nitrogen atom after the initial nitrogen fixation reaction has taken place is not known. This study is an attempt to learn something about the enzymes that are involved in amino acid synthesis. The cell has varying demands for the intermediary metabolites of nitrogen, as the processes of protein and other polymer synthesis vary. In addition, the cell is often confronted with changing supplies of nitrogen and energy, as a function of environmental change. Efficient growth depends upon the optimum utilization of metabolites in response to variation in cellular needs. The bacterium Klebsiella pneumoniae not only has …


Untrastructural Morphology Of Bovine Herpesvirus Infected Cells, Carol Ann Larson Mar 1972

Untrastructural Morphology Of Bovine Herpesvirus Infected Cells, Carol Ann Larson

Electronic Theses and Dissertations

Infectious bovine rhinotracheitis (IBR) virus has been shown to cause considerable economic losses in the South Dakota cattle industry. On the average, one in ten cattle abortions are caused by this virus. This amounts to approximately $250,000 lost each year by South Dakota cattlemen. There is no way of determining the economic loss due to the respiratory infections also caused by this virus. As is the case with most virus diseases, control requires extensive knowledge of its biological, physical and chemical properties. The present study was undertaken to determine the effect of IBR virus on the ultrastructure of a bovine …


A Comparative Economic Analysis Of Representative Sprinkler Irrigation Systems In The Eastern Missouri Alope Area Of South Dakota, Ronald C. Graham Mar 1972

A Comparative Economic Analysis Of Representative Sprinkler Irrigation Systems In The Eastern Missouri Alope Area Of South Dakota, Ronald C. Graham

Electronic Theses and Dissertations

Sizable annual variation in agricultural production and income has long been an obstacle to long-range, agriculturally orientated economic planning and development in the Northern Great Plains states. Paramount as a cause of this obstacle is the inconsistency of crop yields primarily due to annual fluctuations, sometimes severe, in the quantity and seasonal distribution of rainfall. Irrigation is the logical solution for stabilizing agricultural production and income. The development of sprinkler irrigation has the advantages of little or no requirement for land-shaping and of allowing rather exact application of uniform quantities of water. As such it has been considered for some …

Determination Of Salmonella Species In The Big Sioux River And Development Of A Quantitative Most Probable Number Method, Myung Hyun Kim Mar 1972

Determination Of Salmonella Species In The Big Sioux River And Development Of A Quantitative Most Probable Number Method, Myung Hyun Kim

Electronic Theses and Dissertations

In recent years the pollution problems in rivers and lakes have forced the Federal Water Pollution Control Administration to issue requirements for minimum water standards for each State with an interstate stream. Since the Big Sioux River is an interstate river, studies are needed to determine its quality. According to the South Dakota Committee on Water Pollution, water pollution in South Dakota originates from agricultural, municipal, and industrial wastes. For the Big Sioux River, the municipal and meat-processing wastes are the important sources of pollution. Little is known of the sanitary bacteriological quality of rivers and lakes in South Dakota. …


An Expression Of Hybrid Vigor And A Characterization Of Callus Tissue Of Zea Mays L., Judy Winkler Johnson Mar 1972

An Expression Of Hybrid Vigor And A Characterization Of Callus Tissue Of Zea Mays L., Judy Winkler Johnson

Electronic Theses and Dissertations

It is theoretically possible to culture any tissue from any plant or animal, but little work has been done on the major grain crops, especially Zea mays, because they are monocotyledons and present special problems in tissue culturing because of their slow growth. This thesis reports an attempt to grow and redifferentiate callus tissue of corn. The objectives of the research were: (1) to test the ability of different inbred and hybrid corn varieties to form callus and (2) to characterize the callus cell ultrastructure. Since so much is known about corn on the genetic level, it is appropriate to …
