Machine costs are affected by many variables. Size, age, purchase price, maintenance, fuel type, and hours of use each year are just a few of the many factors involved. They may be different in each individual farm situation. List prices employed in arriving at costs are based upon 1979 price levels. These prices may vary because of geographic location as well as special options available on most machines. However, prices used in this publication are believed by the author to be representative of investment requirements for the machines that are listed.

An Econometric Analysis Of The Cash Receipts From Crops In South Dakota, Dennis James Senger
An Econometric Analysis Of The Cash Receipts From Crops In South Dakota, Dennis James Senger
Electronic Theses and Dissertations
It is the intent of this research effort to fill a void left in the previous research efforts. This study will not be concerned with how farmers adjust production in response to price or government policies. The attempt will be made to adept single equation regression models to the examination of how the level of prices and supplies affect a major portion of the income farming sector receives, specifically the cash crop receipts. The specific objectives of this study are as follows: 1. To construct an economet5ric model of South Dakota crop receipts. 2. To demonstrate the model’s use as …
The Effects Of Varying Dietary Protein, Calcium And Phosphorus In Starter Diets For Early Weaned Pigs, Wayne Eldon Schiefelbein
The Effects Of Varying Dietary Protein, Calcium And Phosphorus In Starter Diets For Early Weaned Pigs, Wayne Eldon Schiefelbein
Electronic Theses and Dissertations
Genetic selection by swine producers the past 10 to 15 years has resulted in faster growing, heavier muscled pig. In addition, confinement rearing has placed an increased emphasis upon skeletal development and bone formation. Recent research conducted at Ohio State University indicated that growing swine responded to increasing dietary protein levels if both calcium and phosphorus are also correspondingly increased but maintained at approximately a 1.3:1 ratio. This and other research has led some investigators to believe that the National Research Council's requirements for protein, calcium and phosphorus may not be adequate to support maximum growth and development. Much attention …
The Role Of Allelopathy On The Vegetational Composition Of Disturbed Sites On The Samuel H. Ordway Memorial Prairie, Randy C. Bartels
The Role Of Allelopathy On The Vegetational Composition Of Disturbed Sites On The Samuel H. Ordway Memorial Prairie, Randy C. Bartels
Electronic Theses and Dissertations
The presence of large numbers of cattle in prairie sites can lead to the trampling and destruction of native vegetation in some areas. These damaged, or disturbed sites are typically invaded by a variety of undesirable alien plant species. Many of the alien plant species possess allopathic mechanisms. These allopathic mechanisms enable the alien species to dominate the disturbed sites, and prevent the re-establishment of native plant species. Attempts are currently underway to preserve remaining tracts of native prairie in South Dakota. The Samuel H. Ordway, Jr. Memorial Prairie in McPherson county is one such tract, and is the research …
Hei-Gro Intravaginal Devices And Synovex-H Implants For Feedlot Heifers, James P. Goodman
Hei-Gro Intravaginal Devices And Synovex-H Implants For Feedlot Heifers, James P. Goodman
Electronic Theses and Dissertations
Heifers gain at a slower rate, generally require more feed per unit gain and sell at a lower market price than steers. Due to the fact that heifer carcasses are commonly fatter and contain more waste trim than steers, the value of a heifer carcass is routinely less than that of a steer carcass of comparable yield and quality grade. In the past, the ways in which the livestock operator could increase his profit from feeding heifers were limited. Differential cost of feeder heifers versus steers and feed cost were the major criteria involved in his decision of whether or …
The Effect Of Sodium Hexametaphosphate On Cottage Cheese Yields, Stephen T. Dybing
The Effect Of Sodium Hexametaphosphate On Cottage Cheese Yields, Stephen T. Dybing
Electronic Theses and Dissertations
A major concern in the cottage cheese industry is the inefficient use of the available milk proteins. Currently, the methods of cottage cheese manufacture convert an average of only 74.9% of the milk proteins into cottage cheese, while the remainder are removed in the by-product whey (43, 56). As protein is the main determinant of both the yield and nutritional value of cottage cheese, if 25% of the available protein is lost to the whey, then potential cottage cheese yield and nutrition have been lost as well. The proteins lost in the whey are mainly -lactalbumin and β-lactoglobulin, which remain …
Utilization Of Aspen Pellets As A Partial Roughage Replacement For Lactating Dairy Cows, Deborah Sharples Kipp
Utilization Of Aspen Pellets As A Partial Roughage Replacement For Lactating Dairy Cows, Deborah Sharples Kipp
Electronic Theses and Dissertations
A complete switchback design using ten lactating cows divided into two groups of five was used to evaluate rations containing either (A) 30% dry matter from aspen pellets, 30% OM from corn silage, and 40% DM from a 28% crude protein· concentrate mix, or (B) 60% OM from corn silage and 40% OM from the concentrate mix, to determine if aspen could serve as a partial roughage for lactating dairy cows. All cows were at least 80 days into lactation at the start of the trial. Aspen contained on a DM basis, 1.9% crude protein, 80.3% neutral detergent fiber, 64.5% …
A Comparison Of Cheddar Cheese Yields And Composition Using Conventional Bulk Set Cultures And Superstart Concentrated Cultures, William J. Kipp
A Comparison Of Cheddar Cheese Yields And Composition Using Conventional Bulk Set Cultures And Superstart Concentrated Cultures, William J. Kipp
Electronic Theses and Dissertations
The cheese industry has become by far the largest user of milk for manufacturing. In 1978, cheese production utilized a fourth of the total market supply of milk, up from less than an eighth in 1960 (4). Rising consumer incomes and changing lifestyles and eating habits have increased cheese consumption and sales by 60% since 1960 (21). In the last ten years, annual per capita consumption of cured cheese has increased from 11.6 lb to 17.1 lb (45). Economists state that the cheese market will continue to expand through the 1980's (7, 21, 68). Manufacturing cultured dairy products can be …
An Ultrastructural Study Of Fresh And Ensiled Alfalfa Using The Light And Transmission Electron Microscope, Janet Louise Lazo-Davis
An Ultrastructural Study Of Fresh And Ensiled Alfalfa Using The Light And Transmission Electron Microscope, Janet Louise Lazo-Davis
Electronic Theses and Dissertations
Late bud alfalfa was sampled prior to cutting and after 17 and 51 days of ensiling. Leaf and stem tissue were separated and immediately placed in 2.5% glutaraldehyde followed by 1% osmium textroxide for fixation. Following acetone dehydration, samples were embedded in Spurr plastic for examination under the light (LM) and transmission electron (TEM) microscopes. Light microscopy was used to differentiate cell types and tissues, e.g. epidermis, chlorenchyma, phloem, xylem, and pith. Iodine staining (LM) showed starch localization in chlorenchyma cells. Transmission electron microscopy analysis showed starch localized in chloroplasts of chlorenchyma. Leaf cells averaged nine chloroplasts per cell section …

Feeding And Housing Of Dairy Calves, Lester Vance Schaffer
Electronic Theses and Dissertations
In an 18 mo study antibiotic containing mastitic milk was collected from infected cows and fermented naturally for a minimum of 7 days at ambient temperature. Fermentation of antibiotic containing mastitic milk increased titratable acidity from 0.209% to 0.650% and decreased pH from 7.02 to 5.48. Fermentation decreased crude protein from 3.7% to 3.5% and increased NPN (% TN) from 6.0% to 8.4%. Penicillin was detected at a concentration of 1.2 IU/ml in the first milk after treatment and 0.01 IU/ml when fermented. Species of pathogenic organisms isolated from fresh and fermented milk were Staphylococcus epidermidis, Escherichia coli, Streptococcus dysgalactiae, …
Response Of Lactating Dairy Cows To Small And Large Amounts Of Dried Whey In The Concentrate Mixture, Eugene Walter Skyberg
Response Of Lactating Dairy Cows To Small And Large Amounts Of Dried Whey In The Concentrate Mixture, Eugene Walter Skyberg
Electronic Theses and Dissertations
Short-term (6 to 13 wk) experiments indicated that adding small amounts of dried whey to the concentrate mix fed to lactating dairy cows increase d milk fat percentage, but decreased milk production. In order to determine if the increased fat percentage was a positive response to dried whey in the ration, or an artifact of drying off the cows early, 5% dried whey product (DWP) was included in the concentrate mix fed to 10 Holstein cows. All cows started on the experiment in their 4th wk postpartum and continued for the duration of their lactation. The DWP replaced a portion …
