Methods Of Vitamin A Supplementation For Fattening Beef Cattle, R. M. Luther, L. B. Embry
Methods Of Vitamin A Supplementation For Fattening Beef Cattle, R. M. Luther, L. B. Embry
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1979
The objective of this experiment was to study the effects of administering vitamin A through a mineral supplement or injection on feedlot performance and liver storage of vitamin A. The feeding trail was conducted at James Valley Agricultural Research and Extension Center near Redfield during the summer and fall of 1977. The present study also involved a comparison of conventionally-dried, solar-dried and acid-treated corn. Feedlot performance results for these treatments have been reported in the 1978 Progress Report of the Center.

Silage Making And Silage Additives, L. D. Kamstra, R. M. Luther, R. K. Mcguffey
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1979
Silage formation should be considered a "self-preservation" of a feedstuff by fermentation of some of its nutrients by enzymes present in and/or organisms already present on the feedstuff. The resulting product has been defined as "a feedstuff resulting from anaerobic fermentation of moist forage or other feedstuff and by preservation with the formation of acids." Even under ideal conditions of silage formation, nutrient losses will occur during the fermentation process.
The discussion which follows will include suggestions and criteria for making high quality silage with minimum loss of nutrients.

Utilization Of Drought-Stricken Corn Silage By Yearling Steers, G. Kuhl, C. Carlson, I. Embry, F. Shubeck
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1979
Corn silage is a very versatile and palatable feed that fits well into many cattle feeding programs. Insufficient rainfall in several areas of the country in recent years has resulted in many additional acres of corn being ensiled due to the low potential grain yield. Harvesting drought-stricken corn silage results in at least partial salvage of the crop. However, many farmers have expressed concern about the feeding value of drought-damaged corn silage and how it can be best incorporated into feedlot rations for optimal performance and maximal economic return.

Forced Molting Of Layers, Albert W. Adams
Forced Molting Of Layers, Albert W. Adams
South Dakota Poultry Field Day Proceedings and Research Reports, 1979
Although forced molting of layers is a management practice dating back to 1905, it wasn't until the 1960's that commercial egg producers started to use it extensively as an alternative to all-pullet flocks. Current usage varies considerably within the U.S. Statistics (U.S.D.A.) show that on August 1, 1979, forced molted layers as percent of hens and pullets of laying age were 32 in the western states of California, Oregon and Washington compared to 8.8 in selected midwestern states.

The Effects Of Processed Wheys And Sodium Caseinate On Composition And Consumer Acceptance Of Ice Cream, Dwight Spencer Coder
The Effects Of Processed Wheys And Sodium Caseinate On Composition And Consumer Acceptance Of Ice Cream, Dwight Spencer Coder
Electronic Theses and Dissertations
Ice cream dates back to before the Roman Empire (6), and since has remained a world favorite. In the U.S., consumption of ice cream has been about 8.3 kg per capita per year since 1950 (58). In 1950, the frozen dessert industry used approximately 5.9% of the milk supply; however in 1977 this had increased to 9.4% (58). This represents a sizable portion of the U.S. dairy industry, which in 1978 used 6.2 million metric tons of milk equivalents to produce 4.6 billion liters of frozen desserts, including 3.1 billion liters of ice cream (2). Today, the ice cream industry …

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, …
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 …
Effect Of Sodium Sulfate, Calcium Level And Source And Phosphorus On The Potentiation Of Chlortetracycline And Performance Of Growing Pigs, John P. Balios
Effect Of Sodium Sulfate, Calcium Level And Source And Phosphorus On The Potentiation Of Chlortetracycline And Performance Of Growing Pigs, John P. Balios
Electronic Theses and Dissertations
Experiments designed to study the potentiation of antibiotic in swine were conducted over a two-year period. During the two years, 344 crossbred pigs were used in three separate experiments to study the effects of calcium sources and levels, sulfate sources and levels, and phosphorus levels in diets containing different levels of chlortetracycline. The first experiment was divided into three two-periods. During the first two weeks 50 g/ton of chlortetracycline in the diets increased gain of pigs from 0.68 to 0.72 kg. per day. Pigs fed diets containing chlortetracycline gained significantly faster when the source of calcium was sulfate rather than …
Response Of Strain To Amino Acid Supplementation And Lysine Requirements In Low Protein Layer Diets, John B. Carey
Response Of Strain To Amino Acid Supplementation And Lysine Requirements In Low Protein Layer Diets, John B. Carey
Electronic Theses and Dissertations
Two primary means of meeting amino acid requirements of laying hens, and nonruminants in general, are the use of diets high enough in protein to supply the needed amounts of all amino acids along with some excesses or by feeding low protein diets supplemented with minimum levels of essential amino acids needed for maximum performance. Proper supplementation of these low protein diets requires knowledge of the laying hen's requirement for amino acids and the interrelationships among amino acids, along with information about the influence of factors such as strain and management on these requirements . One purpose of the studies …
N-Acetyl-Dl-Tryptophan And Dl-Tryptophan Supplementation To Low Protein Starter Diets For Swine, Michael Walrod Cox
N-Acetyl-Dl-Tryptophan And Dl-Tryptophan Supplementation To Low Protein Starter Diets For Swine, Michael Walrod Cox
Electronic Theses and Dissertations
Supplementation of individual amino acids to low protein swine diets is of current interest in the swine industry due to attempts to reduce feed costs. Although cereal grains provide the majority of the total protein requirements for swine, the remainder must be supplied either from natural protein supplements or synthetic amino acids. Research has shown amino acid content and balance are of greater importance than total protein alone in meeting nutrient needs. Because of this, a great deal of effort has been directed toward determining single amino acid requirements of swine. Research of this nature is complicated by the varying …

Attitudes Of Teachers And Principals Toward Nutrition Education In South Dakota Elementary Schools, Mary Beth Baker Davis
Electronic Theses and Dissertations
A survey of 361 elementary teachers and 285 principals in the state of South Dakota measured attitudes toward nutrition education in the elementary school. Attitudes of elementary teachers toward teaching nutrition were also assessed. Relationships between attitudes, nutrition knowledge and other characteristics were determined. Results are based on the returned responses of 272 teachers and 262 principals. Significant positive correlations were observed between elementary teachers' attitudes toward nutrition education, nutrition knowledge, and their attitudes toward teaching nutrition. Attitude scores of teachers and principals were found to vary significantly with the inclusion of nutrition in school curriculum and favorable perceptions of …
Embryonic Screening And Isolation Of Pine Needle Abortive Factors, Keith A. Dehaan
Embryonic Screening And Isolation Of Pine Needle Abortive Factors, Keith A. Dehaan
Electronic Theses and Dissertations
Cattleman and veterinarian in the western states and Canada have noted the frequent occurrence of reproductive failure in cattle grazing ranges with tree stands of ponderosa pine (Pinus ponderosa). Consumption of the needles or buds from this tree have caused pregnant stock cows to abort or deliver weak calves. Retained fatal membranes are also frequently associated with pine needle abortion. Surveys conducted by the Black Hills Area Resource and Development Project in 1974 covering eight countries in western South Dakota and eastern Wyoming estimate that at least 600 calves were lost through pine needle abortion in a three year period …

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 …

A Nutrition Knowledge Survey Of Elementary Teachers In South Dakota, Karen E. Pearson
Electronic Theses and Dissertations
If the elementary teacher is to play a significant role in nutrition education, assessing their current status of nutrition knowledge is imperative. Such a data base can assist in determining the nature of educational efforts to adequately prepare elementary teachers for their role as nutrition educators. The primary objective of this research is to determine the present level of nutrition knowledge of elementary teachers in South Dakota. The findings of this study can assist state nutrition education program development by providing: (1) a representative picture of the nutrition knowledge of elementary teachers-presently in the field. (2) information regarding the major …

Catfish Cage Culture In A South Dakota Power Plant Cooling Reservoir, Gary P. Wheeler
Electronic Theses and Dissertations
Studies were conducted to evaluate the Big Stone Power Plant cooling reservoir in northeastern South Dakota as a site for cage culturing channel catfish (Ictalurus punctatus) for market and sport fishery stocking. Temperatures suitable for catfish culture (21-32 C) were present in the reservoir from mid-March through mid-September 1978 and from mid-October through 4 November 1978, the end of the study period. Mean values of chemical parameters analyzed included dissolved oxygen - 8.8 mg/1, total available chlorine- 0.13 mg/1, pH - 8.6, specific conductance - 2228 micromhos/cm, total hardness - 1128 mg/1 as CaC03, calcium hardness - 570 mg/1 as …
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 …
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 …
