Economic Analysis Of The Changing Structure Of The South Dakota Pork Industry, Kevin Keith Weischedel Feb 1981

Economic Analysis Of The Changing Structure Of The South Dakota Pork Industry, Kevin Keith Weischedel

Electronic Theses and Dissertations

In 1979, 3,232,000 hogs were slaughtered in South Dakota. Only seven states in the nation exceeded this total. This places South Dakota in a position of prominence in the national pork industry. There is considerable physical potential for further growth of the South Dakota pork industry. With ample supplies of land, labor, and feed grain available, the number of hogs and pigs in the state could expand. For this expansion in production to occur, state swine growers would have to alter production plans. The decision to increase numbers of hogs and pigs is influenced by many factors at both the …


Effects Of Teenage Parenthood Education On Parenting Attitudes, Knowledge, And Skills, Kristi Yttreness Speaker Feb 1981

Effects Of Teenage Parenthood Education On Parenting Attitudes, Knowledge, And Skills, Kristi Yttreness Speaker

Electronic Theses and Dissertations

The concluding statement of the 1970 White House Conference on Children and Youth was "America's families are in trouble, trouble so deep and pervasive as to threaten the future of the nation". The family is still a concern, as evidenced by the strong affirmation of the need for increased family life education by the 1980 White House Conference on Families. A large majority of national delegates adopted recommendations in support of "comprehensive family life education for children, youth, and adults. 11 Among the courses endorsed by the 1980 White House Conference were Parenting Education and Child Care Skills. Two questions …


Analysis And Evaluation Of An Area Annexation Study For Redfield, South Dakota, Stephen Allen Dunn Jan 1981

Analysis And Evaluation Of An Area Annexation Study For Redfield, South Dakota, Stephen Allen Dunn

Electronic Theses and Dissertations

A major portion of both commercial and residential growth in the Redfield, South Dakota, area was occurring outside the existing city limits of that community in the late 1970's. This pattern was becoming a concern to the Redfield City Council and prompted the city council to contact the Geography Department of South Dakota State University, Brookings, South Dakota, in 1978 to complete a study of annexation for Redfield. The author of this thesis was hired as a research assistant to complete the Redfield annexation study for the Geography Department. The city council needed to evaluate the annexation potential and problems …


Hydrolyzed-Lactose Whey And Nonfat Dry Milk In Ice Cream, Mohammed Serajul Islam Jan 1981

Hydrolyzed-Lactose Whey And Nonfat Dry Milk In Ice Cream, Mohammed Serajul Islam

Electronic Theses and Dissertations

Sweet dry whey was used to replace 25% and 50% of nonfat dry milk solids in ice cream mix. Forty-five batches experimental and control lots of vanilla ice cream were manufactured. A commercial lactase was used to hydrolyze lactose to over 90% conversion and the lactase was inactivated after hydrolysis. The extent of lactose hydrolysis in the mix was adjusted to 50% or 75% by blending non-hydrolyzed nonfat dry milk and whey solids with hydrolyzed preparations. Extra sweetness of the conversion products permitted reduction of sucrose by 6.25% and 12.5%, respectively, in the 50% and 75% hydrolyzed lactose ice cream …


Populations Of Nitrogen-Fixing Bacteria In Soil And Rhizospheres In Eastern South Dakota, Edward B. Anderson Jan 1981

Populations Of Nitrogen-Fixing Bacteria In Soil And Rhizospheres In Eastern South Dakota, Edward B. Anderson

Electronic Theses and Dissertations

A search for alternate sources of fixed nitrogen for crop production has been caused by the rising cost of petroleum used in manufacturing nitrogen fertilizers. Nitrogen in its elemental form, N2, is quite stable, and all organisms except a few of the prokaryotic microorganisms can utilize nitrogen only in some chemically combined form. Those microorganisms which can utilize elemental nitrogen are a potential source of fixed nitrogen to crops. Rhizobium is a genus of nitrogen-fixing bacteria which form nodules on the roots of leguminous plants. This is a symbiotic relationship; the plants supply photosynthate to the bacteria which use that …


Meiotic Studies Of Callus Culture-Derived Indiangrass (Sorghastrum Nutans. L. Nash), Long-Fang Oliver Chen Jan 1981

Meiotic Studies Of Callus Culture-Derived Indiangrass (Sorghastrum Nutans. L. Nash), Long-Fang Oliver Chen

Electronic Theses and Dissertations

Chromosome and genetic instabilities were reported in many plant species (c.f. Partanen, 1963; Sunderland, 1973; Skirvin, 1978; D'Amato, 1976; 1978). D'Amato (1976) suggested that, in higher plants, only meristematic cells were genetically stable; explants excised from stem apices would then ensure genetic uniformity for in vitro plant propagation. However, cultures derived from shoot apices were generally inefficient for vegetative propagation. The usefulness of a tissue culture technique for cloning would then be judged not only by the degree of genetic variation in the tissue culture-derived population, but also by the amount of plantlets initiated from a culture. In this laboratory, …


The History Of Men's Basketball In The Netherlands, James Dale Woudstra Jan 1981

The History Of Men's Basketball In The Netherlands, James Dale Woudstra

Electronic Theses and Dissertations

Within a short time after Dr. James Naismith invented basketball in 1891, the game was being accepted as a new sport in many countries. In the nearly 90 years of its existence, it has grown to be one of the most popular and widespread international sports in the world. Basketball clubs, amateur and professional leagues, and interscholastic programs provide ·competition for almost every age level. The Netherlands is a country where basketball got a fairly late start, but it has grown to become a very popular sport. A study of the history of Dutch basketball should provide such a continuous …


Dye Marking Of Antibiotics Used In Treatment Of Mastitis, Nancy Fairbank Novak Jan 1981

Dye Marking Of Antibiotics Used In Treatment Of Mastitis, Nancy Fairbank Novak

Electronic Theses and Dissertations

The National Mastitis Council, Inc. defines mastitis as the infection of udder tissues (74). Mastitis is the most costly disease affecting dairy cows; many people do not realize the considerable losses due to mastitis (6). A reasonable estimate of the prevalence of mastitis is 50% of cows infected at any time (62); cows in the average herd contract clinical mastitis 1.5 times per year (74). The minimum antibiotic treatments per case of mastitis is two; with approximately 11 million dairy cows in the United States, the annual minimum number of antibiotic treatments is 33 million. In South Dakota, with nearly …

Preservative Effects Of Covering And Propionic Acid On Alfalfa Haylage In Bunker Silos, Thomas Jonathan Oelberg Jan 1981

Preservative Effects Of Covering And Propionic Acid On Alfalfa Haylage In Bunker Silos, Thomas Jonathan Oelberg

Electronic Theses and Dissertations

The preservation efficiency of covering alfalfa haylage with black plastic (polyethylene) and/or treating haylage with propionic acid was studied in two trials. Experiment 1 was designed to evaluate the influence of both covering and treatment with propionic acid on haylage chemical composition and heifer growth. In experiment 1, prop ionic acid was administered to the haylage at the chopper at 0.02% of the fresh forage weight. Chemical composition and ensiling temperature of the haylage were monitored and animal growth was measured with 16 Holstein heifers. Covered haylage was superior to treated haylage in quality as measured by chemical analyses and …


Media Habits Of Students At South Dakota State University, Craig Lee Derscheid Jan 1981

Media Habits Of Students At South Dakota State University, Craig Lee Derscheid

Electronic Theses and Dissertations

A number of researchers have studied the media habits of the general public. They have examined the habits of adults, teenagers and numerous other groups. Only a few researchers have examined the college-aged group, a group which includes both teenagers and adults, and which may reflect unique patterns of media use. This study was designed to examine the news media used by selected subgroups of the college population. The population from which the subjects were chosen for this study included students who were enrolled at South Dakota State University in the fall semester of 1980. The purpose of this study …
