Electronic Theses and Dissertations

In vitro dry matter digestibility (IVDMD) of sunflower hulls (SFH) treated with sodium hydroxide (NaOH), ammonium hydroxide (NH4OH), and potassium hydroxide (KOH) at increasing levels were studied. Tested concentrations of each alkali as percent dry matter (DM) on SFH were 1.63, 2.45, 3.26, and 4. 08. In vitro dry matter digestibility of sunflower hulls increased with higher concentrations of NaOH and KOH. Percent IVDMD for control (un-treated SFH) was 18.0. Percent IVDMD for SFH treated at 1.63, 2.45, 3.26, and 4.08% of DM were: 18.9, 21.4, 22.2, and 22.9 for NaOH; 18.3, 18.0, 18.3, and 18.5 for NH …


Market Structure And Conduct Of The South Dakota Beef Industry, Annette Lorraine Clauson Jan 1983

Market Structure And Conduct Of The South Dakota Beef Industry, Annette Lorraine Clauson

Electronic Theses and Dissertations

While the South Dakota livestock producer desires the best price for his product the day it is sold, he may not always receive it. Information about alternative marketing methods and prices being paid at alternative markets is not always available. If available, this information could lead to more efficient marketing. For example, just a one dollar annual increase in market price of livestock would increase the value of commercial slaughter in South Dakota by approximately $8 million/year. An increase like this would not only benefit the livestock producer; but could result in significant impacts on the economic well-being of the …


Economic Effects Of Rural Water Systems On Agricultural Production And Productivity In Selected Counties In South Dakota, Robert Edward Green Jr. Jan 1983

Economic Effects Of Rural Water Systems On Agricultural Production And Productivity In Selected Counties In South Dakota, Robert Edward Green Jr.

Electronic Theses and Dissertations

Insufficient quantity and quality of water in South Dakota are two reasons rural residents have been turning toward rural water systems to meet their water needs. The first large rural water system was organized in 1962 to serve 700 rural residents near Rapid City. From 1962 to 1970 the growth of rural water systems in South Dakota was slow with only nine systems in operation as of 1970. Currently, the total capital investment for a large system averages $4.5 million. This amounts to an investment of $4,700 per hookup and an average monthly user charge that would exceed $20 if …


The Effect Of Varying Dietary Selenium Levels, Selenium Source And Dietary Composition On Growing Swine, Terry B. Goehring Jan 1983

The Effect Of Varying Dietary Selenium Levels, Selenium Source And Dietary Composition On Growing Swine, Terry B. Goehring

Electronic Theses and Dissertations

During the early 1900's, many stockmen in the western Great Plains suffered huge economic losses due to poisoning of their livestock through consumption of seleniferous plant material. Some were forced to discontinue raising livestock entirely and turned to grain farming. However, grain produced on land high in selenium was discounted on the market. Today, this grain marketing problem does not exist to the extent of that of the early 1900's. Selenium has more recently been recognized as an essential micronutrient for several species including swine. The Food and Drug Administration (FDA) has approved sodium selenite and sodium selenate as supplements …

Replication Of Bovine Parainfluenza-3 Virus In Bovine Alveolar Macrophages : Effects On Phagocytosis And Phagosome-Lysosome Fusion, Richard Allen Hesse

Electronic Theses and Dissertations

Bovine parainfluenza-3 virus was found to replicate in alveolar macrophages in vitro. Cytopathic changes include spindle cell and giant cell formation, cellular detachment, and diffuse cell lysis progressing to total destruction of the monolayer. Direct immunofluorescent microscopy demonstrated viral antigens in greater than 90% of the cells three days after virus inoculation. Virus titers in culture supernatants increased by 6 a factor of 1.6 X 10 TCID50 by six days post inoculation. Phagocytosis assays showed no statistical differences of glass adherent cells in virus infected and control macrophages. When the number of glass adherent cells available for assay are taken …


Parasites Of Three Species Of South Dakota Lagomorphs, Glenn E. Kietzmann Jan 1983

Parasites Of Three Species Of South Dakota Lagomorphs, Glenn E. Kietzmann

Electronic Theses and Dissertations

The wild lagomorpha of North America have in the past been the subject of numerous parasitological examinations. Many of these surveys have been performed on cottontail rabbits, while comparatively fewer studies have been done on the jack rabbits. In South Dakota, parasite surveys have yet to be. completed on both cottontail rabbits and jack rabbits. The representatives of the Leporidae found in South Dakota are the white-tailed jack rabbit (Lepus townsendii campanius), the black tailed jack rabbit (Lepus californicus melanotis), the eastern cottontail rabbits Sylvilagus floridanus similis and Sylvilagus floridanus mearnsii), the desert cottontail rabbit (Sylvilagus audubonii baileyi) and the …


Environmental Factors Influencing The Degradation Of Carbofuran, Douglas E. Raynie Jan 1983

Environmental Factors Influencing The Degradation Of Carbofuran, Douglas E. Raynie

Electronic Theses and Dissertations

As society places a greater emphasis on agricultural production, knowledge of the wise use of farm chemicals becomes increasingly important. Armed with reduced tillage, crop rotation options, remotely sensed data, and other developing technologies, the agriculturalist must have the capacity to properly apply supportive chemicals. Among these chemicals are the pesticides. Thorough knowledge of the breakdown, particularly biologically based degradation, of effective pesticides is lacking in many cases. Carbofuran is a common broad spectrum carbamate insecticide. Because of its wide use there has been a considerable amount of study on the chemical, microbial, and physical factors affecting degradation. Due to …


Suitability Of Selected Organisms For Monitoring Leachate At A Refuse Disposal Site, John Nathan True Jan 1983

Suitability Of Selected Organisms For Monitoring Leachate At A Refuse Disposal Site, John Nathan True

Electronic Theses and Dissertations

If a landfill is improperly managed or improperly located, contamination of the ground water is possible. Once contaminated, the polluted ground water can travel for great distances with little dispersal or interaction with the soil. Once the ground water is polluted it is very costly, if even possible, to alleviate the problem. Over fifty percent of the people in the United States use ground water as a source for drinking water. With landfills located throughout the U.S. and with over one half of the population drinking ground water, it is not hard to visualize the pollution potential from an improperly …


An Examination Of Prostaglandins As Causative Agents In Pine Needle (Pinus Ponderosa) Abortion, Daniel P. Shue Jan 1983

An Examination Of Prostaglandins As Causative Agents In Pine Needle (Pinus Ponderosa) Abortion, Daniel P. Shue

Electronic Theses and Dissertations

Cow and calf losses due to pine needle abortion in cattle grazing foothill ranges of ponderosa pine (Pinus ponderosa) continue to cause managerial and economic problems for ranchers in South Dakota, Colorado, Idaho, California, Montana and many areas throughout Canada. Because of its overall economic significance, investigators have been attempting to isolate and characterize causative agents of pine needle abortion. To date, a large number of pine needle constituents have been shown to possess abortifacient capabilities. In addition to actual pine needles, it appears that several other undefined factors may be associated with, and (or) predispose animals to, pine needle …


Lactational And Chemical Evaluation Of Soybean Meals Heat-Treated By Two Methods, Tilahun Sahlu Jan 1983

Lactational And Chemical Evaluation Of Soybean Meals Heat-Treated By Two Methods, Tilahun Sahlu

Electronic Theses and Dissertations

A series of experiments were conducted to evaluate regular, commercially available solvent extracted soybean mean (SBM), and SBM subjected to additional heat either during desolventizing (HSBM), or by extrusion (ESBM). Soluble nitrogen (14.8, 9.3, and 7.0% of crude protein for SBM, HSBM, and ESBM) and degradable protein (71.0, 68.7, and 58.7% of crude protein) were reduced by heat-treating soybean meal. Nonessential amino acids in soybean meals were more soluble and degradable than essential amino acids. The first five limiting amino acids (methionine, lysine, valine, leucine, and isoleucine) for milk production were the same, although relative order was altered by heat …

The Development Of Palestinian Territoriality, Jan Charles Betholf Jan 1983

The Development Of Palestinian Territoriality, Jan Charles Betholf

Electronic Theses and Dissertations

The land of Palestine has been the object of conflicting claims by numerous peoples and religions for millennia. This small, arid place generally consisting of territory east and west of the Jordan River has been ruled and coveted by Jews, Christians, and Muslims. Each now possesses historical, cultural, and religious attachments to the land. The Jewish claim to Palestine rests on their conquest of the "promised land" in 1451 B. C. E. and their 1500-year occupancy which ended with the Diaspora in 71 A. D. Christian occupation during the crusades and the importance of the land that Jesus walked also …

Vitamin A And Carotene Supplementation On Feedlot Lambs, Donald F. Samuel Jan 1983

Vitamin A And Carotene Supplementation On Feedlot Lambs, Donald F. Samuel

Electronic Theses and Dissertations

After the discovery and identification of vitamin A as an essential nutrient, the role of the vitamin and its precursor carotene in the nutrition of animals came under widespread study. Many experiments have been designed in the past to examine the interrelationships concerning vitamin A and carotene in animal feeding. In view of the similarity of digestive systems between cattle and sheep, it was reasonable to assume that vitamin A and carotene might function much the same in the two species. As numerous investigators have demonstrated, there are many similarities in vitamin A metabolism between cattle and sheep. However, there …


Ultrafiltration Of Skim Milk Prior To Cottage Cheese Making, Izhar H. Athar Jan 1983

Ultrafiltration Of Skim Milk Prior To Cottage Cheese Making, Izhar H. Athar

Electronic Theses and Dissertations

Cottage cheese has the largest sales volume potential of all cultured dairy products in the United States today. Moreover, it can be a highly profitable product if proper control is exercised during its manufacturing (46). Commercial production of cottage cheese utilizes a significant portion of the total fluid milk produced in the U. S.A. After the 1955's, yearly per capita consumption of cottage cheese increased from 1. 7 7 kg (3.9 lb) to a high of 2. 45 kg (5.4 lb) in 1972 (67) . Consumer demand for lower fat dairy products gradually increased, which put more pricing emphasis on …


The Effect Of Various Levels Of Dietary Sunflower Seeds On Performance And Carcass Characteristics Of Growing-Finishing Pigs, Alan D. Hartman Jan 1983

The Effect Of Various Levels Of Dietary Sunflower Seeds On Performance And Carcass Characteristics Of Growing-Finishing Pigs, Alan D. Hartman

Electronic Theses and Dissertations

Sunflower seeds have become an important crop in several midwestern states. In the past, sunflower seeds have been used primarily in the production of sunflower oil and sunflower meal, with some seeds being used in the production of confectionery seeds. Not all sunflower seeds are suitable for these uses. An alternate use of these seeds would be incorporating them into livestock diets. Sunflower seeds may contain 40% or more oil that is highly unsaturated in nature. In swine diets the addition of a fat source such as sunflower seeds would be primarily at the expense of a carbohydrate source in …
