Lasalocid Supplementation For Grazing Steers, L. B. Embry, M. J. Goetz, R. M. Luther

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1983

Management systems for pastures and for the grazing animals can be major factors in the amount and efficiency of production. Several nutritive and nonnutritive products have been reported to improve utilization of pasture forages and animal performance. Improvement in rate and efficiency of production can be of considerable economic benefit. The importance becomes greater with increasing costs and livestock production.
Lasalocid sodium (Bovatec) is a feed additive shown to improve growth rate and feed efficiency of cattle in the feedlot and on pasture. Two experiments were conducted to test the product when fed at 100, 200 or 300 mg per …

Alternative Feed Grains For Sheep, J. M. Thompson

South Dakota Sheep Field Day Proceedings and Research Reports, 1983

South Dakota sheep producers have a number of alternative feed grains they may want to consider for use in meeting the nutritional needs of their sheep flocks. Within certain limitations, sheep are capable of utilizing all of the cereal grains produced in South Dakota. Sheep producers wanting to utilize a particular feed grain for any class of sheep need to consider the nutritive value of that feedstuff and the nutrient requirements of the animals to be fed. The typical composition of some feed grains that might be used by South Dakota sheep producers are shown in table 1.

Waterfowl Pair And Brood Use Of Dug Brood Complexes In East-Central South Dakota, Beth A. Giron Pendleton

Electronic Theses and Dissertations

Modification of wetlands has been a frequently employed management technique to enhance habitat for waterfowl and other wetland wildlife. One type of excavation in wetland basins is the dug brood complex; an interconnected system of pond units, channels, and islands, primarily created to provide waterfowl brood rearing habitat during drought. In 1981-82, a study was conducted to evaluate waterfowl pair and brood use of 8 pairs of Class IV wetlands in east-central South Dakota. Each pair consisted of a wetland with a dug brood complex (modified) and an unmodified basin of comparable basin size. Under drought conditions in 1981, both …

The Use Of Whole-Rolled Sunflower Seeds With Or Without Additional Limestone In Lactating Dairy Cattle Rations, Anne M. Finn

Electronic Theses and Dissertations

Thirty Holstein cows were utilized in a lactation trial evaluating diets containing whole-rolled sunflower seeds. Cows were randomly assigned to treatments, grouped according to previous milk production and lactation number. The cows were fed one of three diets: 1) the control was a com-soybean meal mix (CSM), 2) com-soybean meal mix plus 22% whole-rolled sunflower seeds, and 3) a corn-soybean meal mix with 22% whole-rolled sunflower seeds with an additional 3.5% limestone over SCS (SCL). Additional limestone was added in an attempt to form fatty acid insoluble soaps. Rations were formulated to be isonitrogenous at 16% crude protein, fed as …

Digestibility Of Sunflower Hulls Treated With Sodium, Ammonium, And Potassium Hydroxides, Bal Krishna Sharma

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 …

Exercise Physiology: Energy, Nutrition, and Human Performance 1981, 373). Somatotyping was assessed by use of the Heath-Carter Anthropometric Method. Descriptive statistics were applied to …

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 …

Attitudes Of South Dakota Home Economics Teachers Toward The Use Of Microcomputers, Mary J. Pickard

Electronic Theses and Dissertations

The project was designed to assess attitudes of South Dakota secondary home economics teachers toward computers. Attitude was assessed using an instrument developed by David Ahl for measuring public feeling toward computers. Hypotheses relating attitude to educational background, size of school, years of teaching experience, and exposure to and availability of computers were tested. A secondary purpose was to determine teacher preference for learning how to use computers. A random sample of home economics teachers in 108 schools received the survey instrument. The sample was stratified according to school size. The majority of schools, 90 percent, had computers. However, only …

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

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 …

Effects And Interactions Of Nitrogen And Soil Moisture Status Under A High Yield Irrigated Corn Environment, Dwayne L. Beck

Electronic Theses and Dissertations

A two-part study was conducted during the 1979 and 1980 growing seasons on irrigated lands adjoining the Missouri River in central South Dakota. Empirical [sic] models were developed to describe the response of irrigated corn (Zea mays L.) to soil water status and nitrogen fertilization at a location recently developed for sprinkler irrigation. Nitrogen fertilizer rates of 0, 100, 200, and 400 kg of N/ha were used under water treatments consisting of a 2.5 cm irrigation when soil water matric potential at a depth of 40 cm decreased to -35, -50, and -75 kPa. Yield differences due to soil water …

Health Knowledge Assessment Of College Freshmen Educated In South Dakota K-12, Nadeen E. Lunde

Electronic Theses and Dissertations

Nothing in life is so taken for granted when possessed, or so missed when lost, as is health. Therefore, it is essential to possess basic facts if each individual is to take advantage of medical science advances, protect himself against quackery, and obtain an optimum level of health. Health education is recognized by leading educators as of vital importance in educating our youth, but health education has not established itself in a way comparable to other subjects. Kilander noted this fact as early as 1937, and yet, 46 years later, South Dakota's health education programs have not been established. Many …

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

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 Subject Matter And Content Emphases Of Secondary Home Economics Programs In South Dakota, Darlys Olson Zaske

Electronic Theses and Dissertations

The purpose of this study was to describe secondary home economics programs in South Dakota. Specifically, it was designed to identify subjects being taught and pervasive themes running throughout the subjects of home economics programs. A secondary objective was to investigate the relationship between curricular emphases and certain characteristics of the school and teacher. Variables studied were 1) teaching experience, 2) class enrollments, 3) school size, 4) personal preference of teaching subject, and 5) professional interaction. To determine the curriculum emphases of the teachers, the Curriculum Orientation Survey (COS), developed by Hall, was used to measure the extent to which …

Rumen Microbial Protein Synthesis In Cows Fed Dried Whey, Paul M. Windschitl

Electronic Theses and Dissertations

Two rumen fistulated Holstein cows, weighing approximately 550 kg, were used in a switchback design experiment to evaluate the effects of consuming large amounts (38% of total ration dry matter) of dried whey on rumen microbial protein synthesis. Cows were fed total mixed rations consisting of (dry matter basis) 45% corn silage, 10% alfalfa hay, and 45% concentrate mix. The concentrate mix was primarily corn and soybean meal (control) or 85% dried whole whey. Dry matter intakes averaged 16.4 and 15.3 kg/day for control and whey diets. Concentrations of bacteria and protozoa in rumen contents were estimated using diaminopimelic acid …

Neutron Activation Analysis For Trace Metal Content Of Brookings Sludge For Land Application, Daniel George Dewall

Electronic Theses and Dissertations

The Federal Environmental Protection Agency (EPA) strongly favors land application of sludge as a disposal method and requires communities to consider the application of sewage wastes to land as one of their alternatives to advanced wastewater treatment in order to be eligible for federal funding to improve sewage wastewater treatment facilities. Although use of sewage sludge on the land has definite benefits, several potential problems may develop when applying this method of disposal. One main concern has been the possibility of toxic metal pollution occurring in the application soils. If high concentrations of zinc, copper, lead, cadmium, etc. are present …

Determination Of Body Density Of College-Age Women Using Circumference Measurements, Melinda J. Robins

Electronic Theses and Dissertations

The purpose of this investigation was to determine an effective and simple method of estimating body density of college-age women (n=51), ages 18 to 26 years, using age and selected circumference measurements (thorax, waist, abdomen, hip, gluteal fold and thigh). Two subproblems were also investigated. The first subproblem was to determine if the sum of the selected circumferences was a better predictor of body density than when each circumference was used individually as a predictor. The second subproblem was to determine if body density could best be predicted by a linear or curvilinear relationship. Statistical analysis of the data included …

Protein Needs Of Barrows And Gilts 75 To 225 Pounds, R. C. Wahlstrom, G. W. Libal

South Dakota Swine Field Day Proceedings and Research Reports, 1982

Although a considerable amount of research has been conducted on the protein requirement of growing-finishing barrows and gilts, there is still a discrepancy in the recommendations given. Most research has been conducted by feeding barrows and gilts together. Data have suggested gilts require more dietary protein than barrows.
This experiment was part of a regional project of the North Central Swine Nutrition Committee. The objective of the study was to determine the difference in the protein requirement between barrows and gilts.
