Meeting The Protein Needs Of Growing And Finishing Cattle, William W. Schneider
Meeting The Protein Needs Of Growing And Finishing Cattle, William W. Schneider
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1973
The cost of nearly all feed commodities has sharply risen since one year ago. Those feed ingredients normally used as natural protein sources, however , have risen in cost much more dramatically than the roughages or the cereal grains used for animal feed. This substantial rise in cost of high protein feeds plus possible shortages of feed grade urea will force many cattle feeders to alter feeding and management practices used in the past. For example, recommendations in previous years frequently called for the use of soybean meal or soybean meal based supplements as the source of protein in growing …
Effects Of Confinement Feeding Systems On Beef Cattle Production, R.D. Goodrich, J.C. Meiske, R.E. Smith, H.E. Henke
Effects Of Confinement Feeding Systems On Beef Cattle Production, R.D. Goodrich, J.C. Meiske, R.E. Smith, H.E. Henke
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1973
Several factors have stimulated interest in housing systems for feedlot cattle. Some of these factors are (1) the desire to eliminate problems associated with the use of bedding, (2) the desire to decrease the labor required for feeding, bedding and manure handling, (3) the need to develop effective pollution control measures and (4) the desire to know the effects that housing systems may have on the performance and carcass characteristics of feedlot cattle. The objectives of the trials reported herein were (1) to study the influence of housing systems on the performance of finishing steer calves and (2) to study …

Carcass Characteristics Of Bulls, Heifers And Steers As Influenced By Ration And Market Weight, Peter B. Smith, W.J. Costello, Peter J. Thiex, L.B. Embry
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1973
High feed grain prices, a growing worldwide demand for animal protein, and increasing demand for lean, high quality beef make it imperative that beef volume and production efficiency increase. Because of high feed costs it is important to know how concentrate level in the ration and market weight influence production efficiency and carcass composition of different sex groups. The purpose of this study was to evaluate the effects of market weight and ration concentrate level on the quant itative and qualitative carcass traits of yearling bulls, bull calves, heifers and steers .

Investigation Of Western Yellow Pine (Pinus Ponderosa) Abortion, C. Cogswell, L.D. Kamstra
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1973
For a number of years, ranchers in western South Dakota have been of the opinion that pregnant cows will abort after the consumption of sufficient quantities of yellow pine (Pinus ponderosa) needles. Problem areas exist where the yellow pine is the predominant pine species. Incidence of pine needle abortion is particularly high in late winter and early spring after cows in the last trimester of pregnancy graze on the needles. Some ranchers, however, have experienced the problem throughout the year when cows in earlier stages of pregnancy have aborted. Retained placentas are frequently associated with the abortions. If true abortions …

Growing And Fishing Bulls, Heifers And Steers, P.J. Thiex, L.B. Embry
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1973
Growth rate of an animal depends upon energy consumed in excess of that for maintenance, and the requirements increase as the animal grows and fattens. Male and female cattle differ in rates of growth and fattening, but changes may be brought about by castration. There still is some concern as to the effects of market weight and energy content of rations on weight gain, feed efficiency and carcass characteristics of feedlot bulls, heifers and steers. This experiment was conducted to study these factors. Bulls ( calves and yearlings), heifers and steers were fed to one of two final weight groups. …
Storage Methods And Protein Supplements For High-Moisture Ear Corn, W.S. Swan, L.B. Embry
Storage Methods And Protein Supplements For High-Moisture Ear Corn, W.S. Swan, L.B. Embry
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1973
A high rate of gain can be obtained with growing and finishing cattle fed ear corn adequately supplemented with protein, minerals and vitamins. The cob portion of the ear furnishes more roughage than has been reported to result in optimum gains with minimum problems frequently associated with high-concentrate diets. Other roughages are not indicated with ear corn where high rates of gain are desired. Ear corn contains less protein than recommended in most diets for growing and finishing cattle. The low protein cob portion may not be an economical source of roughage in comparison to those considerably higher in protein …
Weaning Age And Management Systems For Fall Born Beef Calves, William Mccone
Weaning Age And Management Systems For Fall Born Beef Calves, William Mccone
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1973
Seventeen registered Angus, Hereford and Shorthorn cows calved in September, 1972. The cows calved on pasture and remained on pasture until early November. From November 10 to December 29, the cows were bred for 1973 fall calves. On December 29, 1972, 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 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 and …
Adaptation Of Feedlot Cattle To Urea And Antibacterial Compounds, J.D. Burkhardt, L.B. Embry, L.B. Dye
Adaptation Of Feedlot Cattle To Urea And Antibacterial Compounds, J.D. Burkhardt, L.B. Embry, L.B. Dye
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1973
A period of adaptation to urea during which feedlot performance is suppressed is frequently experienced when this product is added to rations of cattle not previously, or recently, fed it. This effect appears more evident with levels of urea used when it forms a major part of total protein in the ration. Urea and antibiotics in combination are common additions to protein supplements or mixed rations. At usual levels for continuous feeding of antibiotics and safe levels of urea for the dietary conditions, the combination appears satisfactory and to offer the beneficial effects from these compounds after a suitable period …
Backgrounding Of Feedlot Cattle - Levels Of Grain On Pasture, L.B. Embry
Backgrounding Of Feedlot Cattle - Levels Of Grain On Pasture, L.B. Embry
South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1973
Utilization of appreciable quantities of roughage for growing and finishing feedlot cattle means some restriction on rate of production in comparison to that obtained from diets containing more liberal quantities of concentrates. Periods of restricted growth of cattle have been shown to be followed by an accelerated rate of growth with an improvement in feed efficiency in comparison to more liberally fed animals during later finishing periods with high-concentrate diets. Thus, there can be some compensation in both rate and efficiency of gain following periods of restriction. However, the amount of compensation may vary depending upon the comparative degree and …

Analysis Of The Republic Of Korea Food Grain Situation, William F. Payne, Kyo Ii Jo
Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)
Two problems for developing economies confronted with food shortages are (1) how to acquire sufficient food and still stabilize food prices in the short-run and (2) how to increase food production and realize food self-sufficiency in the long-run. Solving these two problems is often considered a precondition to achieving steady economic growth and industrialization. This study was concerned with the Republic of Korea, where economic development plans have been initiated during the last two decades under the condition of annual food grain shortages. Efforts to overcome these shortages have resulted in South Korea becoming the fastest growing major market for …

An Economic Profile Of Farms And Ranches In South Dakota, Herbert R. Allen
An Economic Profile Of Farms And Ranches In South Dakota, Herbert R. Allen
Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)
This publication is in response to numerous" questions regarding the number of farms in different size groups within the State of South Dakota. Particular emphasis is placed upon identification of farms under economic size classifications. Data are presented by areas of the state and by counties. Data has been obtained from the 1949, 1959 and 1969 Census of Agriculture. Data on the economic characteristics of farm families is not readily available and it was therefore determined that census data on farms (as distinguished from farm families) was the most useful kind of data for identification of any economic profile.

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), …

Electronic Theses and Dissertations
In an attempt to elucidate the role of nematodes in a grassland ecosystem nematode taxa, number and biomass data was gathered over a three year period at the Cottonwood International Biological Program Grassland Biome site in western South Dakota. The effects of grazing intensity, sampling date and sampling depth were studied. Nematicide treatment of range grasses in field and greenhouse studies was also used to evaluate the role of nematodes. Biomass data was used to estimate the intake of plant feeding nematodes. Results obtained demonstrate that soil inhabiting nematodes constitute a significant proportion of the consumer biomass at the Cotton[1]wood …
A Study Of Energy And Water Transfer In Irrigated And Nonirrigated Sorghum, Loyd Raymond Stone
A Study Of Energy And Water Transfer In Irrigated And Nonirrigated Sorghum, Loyd Raymond Stone
Electronic Theses and Dissertations
Approximately 70% of all precipitation is lost through percolation out of the root zone or by evapotranspiration (evaporation from the soil plus transpiration from plants). Estimation of these water loss processes has generally been on a small scale due to the cost and time required for their measurement. Development of remote thermal scanners has provided a possible means of estimating water loss from surfaces by using the surface temperature. This study was designed (a) to determine water movement patterns in the soil profile and (b) to evaluate the feasibility of using canopy temperatures in estimating evapotranspiration rates from cropped areas. …

A Survey Of The Insect Fauna Of Canada Thistle, Cirsium Arvense, In South Dakota; And Studies Relating To Biological Control By Ceutorhynchus Litura And Cassida Rubiginose, Lance Jerome Nearman
Electronic Theses and Dissertations
A total of 121 indigenous insect taxa representing 9 orders, 64 families, 103 genera and 118 species was collected from Canada thistle (Compositae: Cirsium arvense (L.) Scop.) in South Dakota during 1970 through 1973. This survey identified the major phytophagous and entomophagous insect fauna associated with this noxious weed. The common phytophagous species observed feeding on thistle were all polyphagous and failed to control Canada thistle below the economic level. Field cage releases of adult Ceutorhynchus litura (F.) weevils were made on a thistle infested pasture site located in east central South Dakota during 1972-1973. Ninety-nine weevils were released in …
