The Effect Of Sodium Hexametaphosphate On The Palatability Of The Freeze-Dried Chicken, Ngoc Hoa Giang
The Effect Of Sodium Hexametaphosphate On The Palatability Of The Freeze-Dried Chicken, Ngoc Hoa Giang
Electronic Theses and Dissertations
Freeze-drying has been generally regarded as the mildest method known for drying meats, but even this process has caused undesirable changes in meat quality. The texture of rehydrated freeze-dried meat has been found to be tougher and drier than untreated meats. In addition, the meat may have a "woody" texture. Apparently something has occurred during the freeze-dry process that reduced the water-holding capacity of the meat. This has been reflected in the meat's inability to become fully rehydrated. Sodium hexametaphosphate (SHNP) has been used successfully to increase the water-holding capacity of meat and fowl. No study has been conducted to …
The Influence Of Sodium Phenobarbital On The Hepatic Adenosine Triphosphatase Activity And The Development Of This Enzyme In The Rat, Gerald H. Mettler
The Influence Of Sodium Phenobarbital On The Hepatic Adenosine Triphosphatase Activity And The Development Of This Enzyme In The Rat, Gerald H. Mettler
Electronic Theses and Dissertations
The purpose of this study was two-fold: {A) To obtain information concerning the influence of sodium phenobarbital on the hepatic microsomal enzyme system which reduces adenosine triphosphate in adult male and female rats; (B) To measure the development of hepatic adenosine triphosphatase activity of newborn and infant rats. Intraperitoneal administration of 30 to 150 mgm./Kq. of sodium phenobarbital for three to five days to adult male and female rats did not increase adenosine triphosphatase activity. These findings are rather pertinent since many enzyme systems are stimulated by much lower dosage levels of enzyme inducers, such as sodium Phenobarbital, over a …

Flavor Factors Involved In Acceptability Of Carp For Human Consumption, Clarice E. Shank
Flavor Factors Involved In Acceptability Of Carp For Human Consumption, Clarice E. Shank
Electronic Theses and Dissertations
Carp constitutes one of South Dakota's relatively untapped natural resources. Mis-named a trash fish, it represents a largely unappreciated source of high biological protein food. Little research has been developed to date concerning this vigorous and adaptable fresh-water fish. In Asian and European countries the carp has long been cultivated as a desirable food fish. Introduced into the waters of this country however, the carp competed so successfully against game fish that it soon lost favor. Methods for eliminating carp from lakes and rivers have proved only partially effective. Prejudice against carp as a desirable food fish has continued to …

An Investigation Of The Pollutional Characteristics Of Runoff From Two Feedlots, Paul E. Thormodsgard
An Investigation Of The Pollutional Characteristics Of Runoff From Two Feedlots, Paul E. Thormodsgard
Electronic Theses and Dissertations
The need for runoff facilities at animal feeding operations has just been recognized in the past few years. Concern has been expressed by water pollution control officials in regard to the pollution potential of animal wastes. As a result, regulations to reduce pollution from feedlot sources are being formulated. South Dakota and several states are in the process of drawing up similar regulations. Unfortunately, these regulations are, in some cases, being formulated with limited evidence of the pollution resulting directly from animal feeding operations. A recent study conducted in the Big Sioux River basin in South Dakota indicted that feedlots …
Management And Nutrition Of Early Weaned Foals, Brian P. Thiel
Management And Nutrition Of Early Weaned Foals, Brian P. Thiel
Electronic Theses and Dissertations
With the current trends in horse popularity, the demand for horses as performance and pleasure animals has increased. As this demand has increased, many horses have been retained solely for their ability as working animals. Therefore, many mares have not been bred since pregnancy would hinder their usefulness. If the horse owner is to breed his mare and also use her as a performance animal, he must initially contend with the pregnant mare and after parturition with the often annoying foal. For the mare to produce a foal and also be used as an effective performance animal, the foal should …
An Experiment On The Effects Of Humidity On Screen-Process Stencils, Thomas R. Bresadola
An Experiment On The Effects Of Humidity On Screen-Process Stencils, Thomas R. Bresadola
Electronic Theses and Dissertations
Quality control is management, it is a way of thinking. To function properly, it cannot be isolated in one section of the plant, but rather it must permeate the entire climate of the plant. Management is control through decision making. Decision making requires accurate and complete information, if errors are to be avoided. The quality of the information on which decisions are based determines the quality of the decisions themselves. Quality may be defined by stating what is acceptable, and what is not acceptable. Quality used in this sense varies greatly from plant to plant. The company printing slogans on …
An Eye-Movement Analysis Of Five Ink Colors Printed On Yellow Stock, Robert Charles Clappsy
An Eye-Movement Analysis Of Five Ink Colors Printed On Yellow Stock, Robert Charles Clappsy
Electronic Theses and Dissertations
The use of color combinations of print and paper by commercial printers has increased steadily since 1930. The relation of color-of-print to color-of-background is an important factor to be considered in printing because color does effect legibility. The increased use of color emphasizes the need for scientific knowledge concerning the effect on legibility of various color combinations of print and background. Such scientific knowledge demands relevant research in many areas of color printing. This study will try to determine the effects on eye-movements of various ink colors printed on a controlled yellow stock. This information would be useful to printers …
Physical Conditioning And Ammonium Carbonate Affecting Blood Ammonium And Swimming Performance Of Dogs, Larry Alan Bjurstrom
Physical Conditioning And Ammonium Carbonate Affecting Blood Ammonium And Swimming Performance Of Dogs, Larry Alan Bjurstrom
Electronic Theses and Dissertations
Ammonia is produced by the working muscle of exercising mammals and cellular metabolic process of resting mammals. Normally relatively minute blood ammonium-nitrogen (BAN) levels are present because mammals have efficient systems for excreting ammonia or converting it to non-toxic end products. Impaired or inadequate detoxification process allow elevated BAN levels with excessive ammonia production. Above normal BAN levels produce deleterious effects which are well known to many research fields. When impaired or inadequate detoxification process occur in an exercising mammal, deterioration of performance is manifested in physical exhaustion and fatigue. Mobilization and enhancement of the KrebsHenseleit urea cycle by addition …

Studies On In Vitro Boar Semen Storage, Wayne L. Singleton
Electronic Theses and Dissertations
Experiments were conducted in a study of in vitro boar semen storage. Yorkshire boars and Yorkshire-Hampshire crossbred gilts were used and were fed a 16.0% crude protein ration. The sperm-rich fraction of all ejaculates was collected by the gloved-hand technique at a minimum of 48-hr intervals. One experiment involved separating the seminal plasma from the spermatozoa cells within 30min after ejaculation by centrifugation (550 g for 7min) followed by two washings with a glucose-bicarbonate solution. The cells were resuspended in a glucose-bicarbonate solution. The cells were resuspended in a glucose-bicarbonate solution and in glucose-bicarbonate solution plus 20% egg yolk. Percent …
Replacement Of Protein With Amino Acids In Diets For Laying Hens And Turkey Poults, Edwin J. Novacek
Replacement Of Protein With Amino Acids In Diets For Laying Hens And Turkey Poults, Edwin J. Novacek
Electronic Theses and Dissertations
Low protein diets were formulated for experiments with laying hens and turkey poults. The diets were supplemented with equal amounts of protein and different feedstuffs while maintaining equal calculated levels of selected amino acids. Single trails were also reported for factorially applied amino acid supplements to turkey starter and cage-layer diets. The three-year studies indicated that a typical corn-soy layer diet diluted with glucose monohydrate to 9.4 percent protein was deficient in methionine, lysine and tryptophan. Attempts to further improve the rate of egg production by additional supplements of arginine, isoleucine, valine, or diammonium citrate were not successful. The low …

Effect Of Days Open On Lactation Production, Roger L. Ripley
Effect Of Days Open On Lactation Production, Roger L. Ripley
Electronic Theses and Dissertations
Accurate evaluation of dairy production records is essential if dairymen are to establish and maintain profitable dairy herds and efficient culling programs. Improper record evaluation may result in. saving breeding stock that otherwise might be eliminated. Many factors may influence the validity of individual production records. Adjustment factors, currently in use by the United States Department of Agriculture (USDA) for sire and cow evaluations, are generally accepted as removing the majority of these influences. Consequently, these factors are invaluable to practical dairymen. The adjustment factors, suggested by McDaniel, et al. (24) in 1967, take into account the geographical location, season …
An Economic Analysis Of Selected Irrigation Systems Applicable To The Eastern Missouri Slope Area Of South Dakota, Myron W. Wolff
An Economic Analysis Of Selected Irrigation Systems Applicable To The Eastern Missouri Slope Area Of South Dakota, Myron W. Wolff
Electronic Theses and Dissertations
For many years the prospect of irrigation development has captured the minds of farmers, agribusinessmen, and residents of the Eastern Missouri Slope area of South Dakota. The area has shared in the over-all technological advance in agriculture, but agricultural production and incomes have remained highly variable. This variability is generated by inconsistent yields caused by extreme annual fluctuations in the quantity and seasonal distribution of rainfall. Irrigation is the logical solution for stabilizing production and income. In the last decade there has been a major transition from gravity to sprinkler irrigation systems. Economic and physical factors have caused the trend …

Effects Of Orally Administered Allopurinol (Hyroxyprazolo 3,4-D Pyrimidine) On Uric Acid, Selected Blood Lipid And Hemogram Parameters In Rabbits, Gary A. Thibodeau
Electronic Theses and Dissertations
Gout is one of the earliest disease entities to be described in medical writings. Hippocrates noted familial distribution patterns and described its classic symptomatology in the 5th century B.C. Empirical treatment employing colchicine was advocated by Alexander of Tralles in the 5th century A.D. A better understanding of the complex association between clinical manifestations of gout and uric acid, carbohydrate and lipid metabolism has made rational treatment possible only very recently. Ample experimental and clinical data now available show a definite association between disorders of purine metabolism resulting in hyperuricemia and frequent concomitant hyperlipidemia. A high incidence of both …

Ochratoxin In Poultry Feeds : Toxic Effects On Hens, Harlal Choudhury
Ochratoxin In Poultry Feeds : Toxic Effects On Hens, Harlal Choudhury
Electronic Theses and Dissertations
Ochratoxin is a toxin produced by fungus Aspergillus ochraceus Wilh. This is one of the poisonous metabolites, like aflatoxin, which when ingested by livestock, poultry, and human beings could produce toxigenic effects—so-called mycotoxicoses. The fungus A. ochraceus is widely distributed in nature and often found in soil and vegetation. Scientists, while searching for causative agents of certain diseases not of bacterial, viral, or nutritional origin, conducted a series of experiments a few decades ago using different species of fungi grown on food and feedstuffs. Toxic effects concurrent with antimicrobial activity of certain species of molds created problems in separating one …

Infiltration Lagoons As A Tertiary Treatment Device, Terry L. Druyvestein
Electronic Theses and Dissertations
As the United States continues to grow and expand industrially, increased mechanization and shorter work weeks will result in a populace which will expect to enjoy increasing amounts of leisure time. Part of this leisure time will be used to participate in outdoor recreation activities, the result being an increased demand on lakes and streams. Maintaining these waters in a suitable condition for recreation and other beneficial uses has become the concern of most Americans. The Water Quality Act of 1965 and the subsequent state water quality standards are ample proof of the concern given to the control of water …
Flannery O'Connor And The Development Of The Grotesque In American Literature, Joan Rae Griffin
Flannery O'Connor And The Development Of The Grotesque In American Literature, Joan Rae Griffin
Electronic Theses and Dissertations
When man's view of himself as a being in his universe changes with the tide of events, literary conventions change as well. There is very little in contemporary life that would contradict the assumption that man's view of himself and of his world is no longer governed by the assurance of reason or the confidence of prediction. When certainty of man's place in the universe was commonly accepted, for instance in the eighteenth-century, this assurance was reflected in a literature which was essentially rational and ordered. In the last two centuries, drastic upheavals in the course of human events have …
Supplementation With Vitamins A And D Of Beef Cattle Finishing Rations Containing Various Levels Of Carotene From Corn Silage And Corn Grain, Harold Richard King
Supplementation With Vitamins A And D Of Beef Cattle Finishing Rations Containing Various Levels Of Carotene From Corn Silage And Corn Grain, Harold Richard King
Electronic Theses and Dissertations
The purpose of this experiment was to determine the need for vitamin A and vitamin D supplements with rations composed of various levels or corn silage and corn grain when fed to cattle. Early investigations with vitamin D demonstrated that the reduced intensity or sunlight during the winter months resulted in decreased cutaneous formation of vitamin D and that dark- skinned animals synthesized less vitamin D than light skinned animals under given conditions of light intensity. Thus this experiment was conducted with Angus and Angus x Hereford crossbred steers and, to the extent possible under seasonal conditions considered to be …
