Electronic Theses and Dissertations

This research is a study of a morphogenetic shift of the soybean shoot apex from quiescence to germination. The minute changes in the organelles were recorded with the use of stereological methods. The ultrastructural data was statistically analyzed. The ultimate goal was the recognition of relationships between the cell's functional units and its structural units, with the identification of morphogenetic regulation mechanisms. Morphometric image analysis of cellular organelles indicated that storage reserves were transformed from lipid bodies to plastid starch. Proplastids and promitochondria, so difficult to differentiate in early stages of germination became obvious by 96 hours post germination. Significant …

The Effects Of Sex And Delayed Chill On The Biophysical And Organoleptic Properties Of Intact And Restructured Beef Steaks, Bruce Colin Paterson

Electronic Theses and Dissertations

The meat industry presently utilizes large, inefficient storage coolers for cooling carcasses rather than more efficient systems for cooling edible boneless meat. When these facilities are combined with the practice of chilling, reheating and rechilling tons of product each day, the need for efficient processing systems becomes evident. It is this inefficiency which has led to hot processing. Hot processing is the removal of bone and trim prior to chilling and it has several possible economic benefits: (1) removal of bone and trim prior to chilling which reduces the energy required to chill; (2) more rapid chilling; (3) decreased refrigeration …

The Effects Of Limited Energy Supplementation On Pasture And Level Of Dietary Energy In The Feedlot On The Finishing Performance And Carcass Traits Of Beef Cattle, Mark J. Goetz

Electronic Theses and Dissertations

Traditionally, pasture and range have been the major source of nutrients for grazing animals. The manner by which ruminants survive and thrive on range with no additional nutrients other than those supplied by forage is unique in the animal kingdom. Nevertheless, western man has cultivated a taste for grain-finished beef. To meet that demand, modern beef production involves both the grazing of forages and the feeding of rations high in concentrates. Major disruptive changes, either physical (as in prolonged drought) or economical (fluctuation in market prices) encourage the reexamination of traditional systems. Within the last 10 years, extreme fluctuations in …

Effects Of Dietary Dehydroepiandrosterone (Dhea) On Body Weight, Food Consumption, And Glucose-6-Phosphate Dehydrogenase (G6phd) Activity In Lethal Yellow (Ay/Aw) And White-Bellied Agouti (Aw/Aw) Mice (Strain 129/Sv), Lisa Deette Staber

Electronic Theses and Dissertations

Dehydroepiandrosterone (DHEA) is a non-competitive inhibitor in vitro of glucose-6-phosphate dehydrogenase (G6PDH), the rate controlling enzyme in the pentose-phosphate shunt. This pathway produces NADPH, a necessary co-factor for the synthesis of fatty acids and ribo- and deoxyribonucleotides. Some researchers believe that by decreasing G6PDH activity, DHEA produces an anti-obesity and anticarcinogenic effect in laboratory mice and rats genetically inclined toward obesity and cancer. It is DHEA's anti-obesity effect which lends it to the study of the yellow obese (AY/-) mouse with its peculiar pleiotropic syndrome. Yellow obese AY/AW mice were found to be more susceptible to dietary DHEA's effects than …

The Economic Feasibility Of Small Scale Cooperatively Organized Fuel Alcohol Production In Eastern South Dakota, Daryl Arthur Brehm

Electronic Theses and Dissertations

Research on the economic feasibility of a cooperatively organized small-scale fuel alcohol plant is justified for several reasons. Policy makers could consult the results of this study as an aid in making decisions about public subsidies for fuel alcohol production. Investors concerned about the wisdom of allocating capital to this type of fuel alcohol production facility are also potential beneficiaries of this research. Perhaps most importantly, this information would be valuable to farmers in eastern South Dakota. Alcohol plants organized on a cooperative basis could reduce the individual financial risk of farmers involved--by spreading commitments among all the cooperative's members. …

Effects Of Anabolic Implants And Breed Group On Carcass Traits And Palatability Characteristics Of Bullock Beef, Roger C. Johnson

Electronic Theses and Dissertations

The ultimate goal of the beef industry is efficient production of beef that satisfies the consumer and increases demand. In the past, American producers have been primarily interested in the production of high quality beef because consumers were concerned with meat palatability, particularly tenderness. However, due to current diet-health issues and economic conditions, American consumers have come to expect acceptable palatability and are now more concerned with the nutrient density and cost of their meat purchases. Maximum production efficiency must be realized to keep beef competitive with other protein sources for consumer dollars. Production systems must be used that are …

Polyperiod Linear Programming Analysis Of A Brookings County Irrigated Farm, Paul Kiendl

Electronic Theses and Dissertations

In the U.S., agriculture is a major industry which produced approximately $529 billion worth of goods in 1982. Agriculture directly employs 3 percent of the U.S. work force, while another 19 percent is employed in manufacturing, processing, transporting, and retailing agriculturally related products. In the past few years, this major industry has experienced a turbulent economic period. The general economic recession in the world coupled with the elevated interest rates have depressed the financial position of the agricultural sector. In 1981, both short-and long-term interest rates reached post World War II record highs. More significantly, the real interest rate rose …

Factors In Ultrafiltration And Thermal Concentration Of Whey Affecting Commercial Lactose Crystallization, Howard Henry Bonnemann

Electronic Theses and Dissertations

The source for lactose production in the United States is almost exclusively sweet (low acid) whey which is the byproduct of cheese manufacture. Its extraction from the whey is motivated largely by pressures to utilize whey components to advantage. The ability to recover lactose efficiently is important to the manufacturers because they are in business ·to make a profit. At current market prices this profit margin will be difficult to realize unless an operation is fairly large a11d quite efficient. However, when considering the alternative of disposing of whey or its components, including lactose, as waste instead of attempting to …

Bull Behavior And Pregnancy Rates, R. J. Pruitt

South Dakota Cow-Calf Field Day Proceedings, 1984

Successful reproductive management of the beef cow herd includes having a high percentage of cows calving during the first 21 days of the calving season as well as a high percentage of cows calving. Nutrition, herd health , crossbreeding systems and evaluation of bulls for reproduction potential are all management areas that need attention in attaining these goals. Current guidelines for evaluating the reproductive potential of bulls include a 'physical exam, measuring scrotal circumference and evaluating semen (Breeding Soundness Exam , Society for Theriogenology). When conducted by an experienced person , these are relatively simple procedures that should be considered …

Budgets For Major Livestock Enterprises In South Dakota, H. R. Allen, W. G. Aanderud

Agricultural Experiment Station Circulars (1920-1915)

Budgets in this publication reflect normal input-output expectations. They are intended to serve as planning guides for farmers and ranchers, teachers, extension personnel and other individuals or groups who may have use for such information. No single budget can reflect the private situation of all individual producers. There may be variations in the ration being used, rates of gain, starting weights, selling weights, calving rates or overall production efficiency. These are just a few of the variables involved. Price is perhaps the single most important variable affecting return above cost from one year to the next. Therefore, provision is made …

Evaluation Of Three Rations On Growth And Reproductive Performance For Replacement Heifers, L. B. Bruce, H. L. Miller

South Dakota Cow-Calf Field Day Proceedings, 1984

Nutrition following weaning of replacement heifers affects their performance as cows. Low levels of energy can delay puberty and reduce conception rates. Excessively high levels can decrease milk production and life span. Previous research indicates that gains should be kept to about 220 pounds from weaning to first breeding. This level of gain precludes high concentrate rations, curtailing flexibility and ability to minimize feed costs when concentrates are a cheaper source of energy. Limiting feed intake to supply desired total energy consumption would allow flexibility and use of higher percentage grain when economical. Limit feeding has been studied with finishing …

Cow Efficiency Update, C. A. Dinkel

South Dakota Cow-Calf Field Day Proceedings, 1984

No important differences have been found between breed groups and no effect of cow size on cow efficiency has been detected. These results appear to be in agreement with other published reports dealing with cow size and breed differences where (1) the annual energy intake for the cow and calf has been measured, (2) the output resulting from net energy input has been measured, and (3) the cow has been fed sufficient energy to maintain reproduction. These experiments have been conducted in environments from Texas to Canada and with a variety of methods used to determine intake level of the …

Grazing Potential Of Major Soils Within The Black Hills Of South Dakota, Daryle L. Bennett

Electronic Theses and Dissertations

Silvicultural management applied by the United States Forest Service (USFS) utilizes a system of intermediate thinning cuts rather than clearcutting. This practice results in a rich understory of vegetation supporting significant wildlife populations. In 1980, 62,000 deer were estimated to be present within the Black Hills. The understory, in conjunction with the adjacent open parks and stream meadows, also supports another valuable resource the livestock industry. Over 29,000 cattle grazed nearly 486,000 hectares of Black Hills National Forest grazing allotments in 1980, totaling approximately 128,000 AUMs (animal unit months) seasonally. However, only 194,000 hectares of forest are classified as suitable …

Pesticide-Pesticide Interaction In Organophosphorus Insecticide Degradation, Peter E. Cheng

Electronic Theses and Dissertations

The widespread use of pesticides during the last two decades has played an important role in the development of today's agricultural system and is one of the major topics of modern science. It is also expected to assist in meeting the nutritional needs of the rapidly expanding populations in the world. The organophosphorus insecticides are among the most toxic pesticides employed for agricultural pest control. However, organophosphorus insecticides are usually rapidly degraded and eliminated. There has been a great amount of study on the chemical, microbial, and physical factors affecting degradation of organophosphorus insecticides, but degradation pathways and behavior have …
