History Of Extension, Cooperative Extension Service, South Dakota State University, Epsilon Sigma Phi, South Dakota Chapter

SDSU Extension Publications Archive

The College had been doing a certain amount of Extension work since 1901, 13 years before the Smith-Lever Act was passed. This work consisted mainly of holding farmers' institutes, addressing farmers' meetings and judging at county fairs. During this 13-year period (1901-1914), four different superintendents were employed. Stacy Cochran served for two years. The work was discontinued for two years, and in 1905 it was reestablished under M. F. Greeley. He was succeeded in a short time by A. E. Chamberlain. The last man to hold the position before the work finally merged into Extension work was H. F. Stoner …

Biology And Ecology Of False Wireworms In South Dakota (Coleoptera: Tenebrionidae), Carrol Otto Calkins

Electronic Theses and Dissertations

False wireworms were important pests of wheat on the Great Plains during the early 20th century. Until recently, they were of little importance; however, they are now occasionally appearing in damaging proportions. The purpose of studying the biological and ecological aspects of these insects in South Dakota was to understand the factors responsible for their demise and the circumstances that could affect the recurrence of damaging populations. The more common species of false wireworms found in South Dakota during this study were Eleodes suturalis (Say), E. opaca (Say), E. hispilabris (Say), E. tricostata (Say), E. extricata (Say), E. obsoleta (Say), …

Cost Of Producing Beef With Different Types And Weights Of Cattle, Danny G. Fox

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1972

Currently, there is much interest in changing the U.S.D.A. grading standards. Some suggest that we completely eliminate the use of them. There are many reasons for this, but the major one is that many feel that the present system does not always correctly identify the most desirable carcasses. Many cattle now come to market at 15 to 18 months of age and are not marbled because of their youthfulness.

Effect Of Sex And Hormonal Compounds On Feedlot Performance And Carcass Merit Of Cattle, L. B. Embry

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1972

Bulls gain faster and more efficiently than heifers. Removal of the gonads (bulls or heifers) reduces rate of gain, increases feed requirements and results in changes in carcass characteristics. Some hormone and hormone-like compounds are commonly used for feedlot cattle. Effects on feedlot performance have been shown to vary between male and female and between intact and castrated animals. In addition, comparative performance between males and females and response to growth promoting compounds have been shown to be influences by the diet, age and stage of fish.

Effect Of Nutrition On The Carcass Composition And Quality Of Cattle, R. L. Preston

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1972

Beef is a highly desirable food, both nutritionally and for the pleasure it gives during its consumption. Protein of high quality is the major nutritional asset of beef, as well as supplying certain minerals and vitamins. As important as this role is, it is not the main reason that beef is the most desired of all meats. Beef is consumed because it provides great satisfaction. What then contributes of this satisfaction?

Feedlot Performance Of Bulls And The Response To Diethylstilbestrol Or Zeranol, P. J. Thiex, L. B. Embry

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1972

The objective of this experiment was to determine the response by feedlot bulls to DES and zeranol when administered at a younger age (about 10 months) and a lighter weight (about 500 lb.).

U.S.D.A. Quality And Yield Grades For Beef, Dan H. Gee

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1972

The market value of a beef carcass at the present time is primarily determined by two factors: (1) the quality of the meat (palatability) and (2) the quantity or amount of lean meat available.

Effect Of Breed On Carcass Merit, D. D. Dearborn

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1972

Ten years ago most cattle found in feedlots in the Corn Belt and the Northern Great Plains were straightbreds representing one of the British breeds. However, with the increased use of Charolais and the importation of bulls from at least 12 other European breeds into Canada, a large variety of breeds and breed crosses is found in the feedlots at the present time. This increased variety along with emphasis on increased efficiency has caused many feeders to ask questions concerning the performance of these breeds and breed crosses. The purpose of this paper is to review research results in an …

Sulfur And Methionine Supplementation With Urea For Feedlot Cattle, B. E. Davidson, L. B. Embry

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1972

Efficiency of urea utilization may be affected by several factors. Among these are level and source of energy, level and source of protein and amount of urea in the total diet and in the supplement. Other essential nutrients in the diet should be properly balanced. There has been a tendency in recent years to use higher levels of urea than was earlier recommended. Under some conditions, urea has been satisfactory as the only supplemental protein to diets for cattle. However, consideration should be given to likely problems of palatability and potential toxicity as well as to efficiency of urea utilization.

Corn Silage Diets For Finishing Cattle When Supplemented With Soybean Meal Or Urea And Des Fed At 10 Mg., 20 Mg. Daily Or Implanted, L. B. Embry, L. B. Dye, F. M. Byers

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1972

Corn silage properly supplemented with protein, minerals and vitamin A forms a simple and efficient diet for growing and finishing cattle. Rate of gain will be less than for high-concentrate diets, especially during late stages of finishing. However, gain per acre of corn will be greater when fed as silage than as grain.

Toxicity Study Using Pine Sawdust As A Roughage Replacement In Gestating Beef Heifer Rations, A. L. Slyter, L. D. Kamstra

The purpose of this was to determine what difficulties might be encountered as a result of feeding raw pine sawdust to beef heifers during the last trimester of gestation.

Weaning Age And Management Systems For Fall Born Beef Calves, William Mccone

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1972

Twenty-five registered Angus, Hereford and Shorthorn cows calved in September, 1971. The cows calved on pasture and remained on pasture until early November. From November 12 to December 29, the cows were bred for 1972 fall calves. On December 29, 1971, one-half of the calves were weaned and started on a self-fed ration. The remaining one-half of the calves were allowed to continue nursing the cows, but the calves also had access to a calf creep feeder containing the same ration used for the weaned calves. At the start of the experiment the calves were randomly divided by sex, breed …

Diethylstilbestrol, Melengestrol Acetate And Zeranol During Growing And Finishing Of Feedlot Heifers, P. J. Thiex, L. B. Embry

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1972

Hormone and hormone-like compounds are commonly used for feedlot heifers. Effects on feedlot performance and carcass characteristics appear to vary depending on compounds used, levels administered including frequency of implanting, stage of growth and fattening, and dietary conditions. This experiment was one in a series to study the effects of melengestrol acetate (MGA) and implants of diethylstilbestrol (DES) or zeranol administered to heifers during growing and finishing or during finishing only.

Choosing Breeds And Crossbreeding Systems By Computer, C. A. Dinkel, D. D. Dearborn

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1972

The first report dealing with this project appeared in the Cow-Calf Field Day bulletin, August, 1972. That report presented an example to demonstrate the utility of the program for the cow-calf man. The example was based on estimates of performance traits for specific breeds under a particular environment and management situation and on market conditions existing at that time. The management system basic to the program took the weaning calf to 700 pounds in a backgrounding phase and then through a 140-day feedlot phase which was split into a 50-day growing period and a 90-day finishing period. The purpose of …

Recognizability And Reproducibility Of Airphoto Interpreted Landscape Units, Robert Dean Heil

Electronic Theses and Dissertations

A physiographic terrain analysis study using the principles of airphoto interpretation was made: (1) to determine the internal homogeneity of airphoto interpreted mapping units, (2) to determine the variability in characteristics among different occurrences of the same mapping unit, and (3) to determine if the units differentiated were sufficiently different to warrant discrimination. The study was conducted in Sedgewick County, Colorado. The study area was comprised of four distinctly different land forms [sic]: a major river and its associated floodplain and terraces; a level to nearly level loamy upland plain; a level to sloping sandy upland plain; and steeply sloping, …

Carboxymethylcellulose As A Carrier For Follicle Stimulating Hormone In The Female Rat And Bovine, C. Leroy Johnson

Electronic Theses and Dissertations

A series of biological assays were conducted to compare physiological saline (PSS) and carboxymethylcellulose (CMC) as carriers for follicle stimulating hormone (FSH) and to determine the optimum ratio of FSH to CMC. Constant individual dosages of 0.5 mg FSH were injected into a total of 384 immature female rats in four experiments. Treatments included single injections of FSH in PSS, FSH in 1 percent CMC at ratios (mg FSH: ml CMC) OF 1:3, 1:2, 1:1, 2:1, 3:1, 5:1 and FSH in 2 percent CMC at a ratio of 1:1. Parameters of primary and secondary response were ovarian and uterine weight, …

Evidence For The Presence Of Two Nucleases In Barley Tissue And The Influence Of Genotype On Their Properties, Clay G. Johnson

Electronic Theses and Dissertations

Several lines of evidence have shown that genetic variability exists within the barley species (Hordeum vulgare L.) with respect to the kinetics and specificity of yeast ribonucleic acid degradation. Initial efforts demonstrated that ribonuclease (RNase), in the crude soluble protein fraction from the cultivar Dicktoo, was inhibited by KC1 and phosphate. RNase activity was enhanced if heated to 60 C for short periods. In contrast, RNase in the crude soluble protein of the cultivar Tennessee Winter showed no altered response by either KC1 or phosphate. Maximal RNase activity was at pH 5.0 for extracts of both cultivars (0.16 M KC1), …

Estimation Of N Availability And No3-N Movement In Soils, Raymond Charles Ward

Electronic Theses and Dissertations

Objectives of this study were: (a) to evaluate several N soil tests that are used to estimate soil N availability, and (b) to measure the distribution of inorganic N in the soil profile after an application of fertilizer N. Small grain yield response from an application of 17, 34, or 67 kg N/ha was used as the parameter of N availability. These parameters were related to 23 independent variables by use of a step wise multiple regression program. Nitrogen soil tests and climatic factors (rainfall and temperature) were the independent variables involved in the analysis. Nitrogen soil tests included were …
