Manual Of Operating Procedures For A Computerized Farm Financial Information System, Herbert R. Allen, Kent Scofield

Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)

The computerized farm information system described in this publication was developed by South Dakota State University Farm Management research workers. The system is designed to provide detailed data on cash flow patterns, enterprise costs, net worth, net income, family living, depreciation schedules and business operating ratios. The program is written in FORTRAN and is operational on the IBM System/360-Model 30 with 64K storage capacity. Large capital investments and greater dependence upon borrowed capital to finance highly technical farming operations requires farm operators to have sharper analytical tools than ever before. Modern computers are helping to provide these tools. However, efficient …

Swine Health: Respiratory Diseases Of Swine, Cooperative Extension Service

SDSU Extension Special Series

Chronic pneumonia is said to be the most costly disease of swine in the world. Pneumonia causes considerable death loss in swine of all ages. It also causes poor performance, slow gains, and poor feed utilization in chronically infected animals. This condition is the number one problem of swine production today. Modern confinement rearing also contributes to the problem. Large numbers of hogs living in close proximity provide ideal conditions for the spread of infectious agents from one to another. Poorly managed swine facilities, with less than adequate ventilation "add fuel to the fire." At the present time there is …

Swine Health: Swine Arthritis, James H. Bailey, Cooperative Extension Service

SDSU Extension Special Series

Arthritis of swine is of economic importance to the swine producer and the meat packer. Recent figures from USDA meat inspection records have shown an increasing trend in condemnations of parts of carcasses and of whole carcasses due to arthritis. Figures for 1969 show a multimillion dollar loss due to trim and condemnation on the packing floor. This is only a small portion of the actual loss. Most losses due to arthritis are suffered by the producer in terms of slower and less efficient gains. Death losses may occur from the septicemia due to the infectious agent in the blood …

Seasonal Movements And Behavior Of Ring-Necked Pheasants In Eastern South Dakota, Arthur V. Carter

Electronic Theses and Dissertations

Information was gathered on mobility, behavior, and related activities of pheasants from July 1966 to July 1968 by banding and/or marking 160 birds with backtags and radio transmitters. Food was readily available since the winters were mild with little snow. Birds moved less than 1/4 mile from roosting areas to cornfields and weed patches to feed. Numbers of birds dispersing from the study area in spring varied each of the years, but 60 to 70 remained there during the two reproductive seasons. Adult cocks traveled less than 1/4 mile when dispersing-and adult hens moved less than 1/2 mile. Movements by …

Effects Of Chick Stimuli And Dieldrin On Adoptive Behavior Of Penned Hen Pheasants, K. L. Cool

Electronic Theses and Dissertations

Studies to determine the effect of chick stimuli and dieldrin on adoptive behavior of penned hen pheasants were conducted in 1969 and 1970. Results indicated that whether caged hens saw or heard chicks had no effect on adoption or killing of chicks. Hens receiving sound stimuli and sight-and-sound stimuli from chicks responded similarly to hens receiving no stimuli. Sub-lethal doses of dieldrin also had no effect on chick adoption under the conditions of this study. Results demonstrated that non-incubating pheasant hens will adopt and brood orphan chicks. During the 2 years of the study, respectively, 37 and 49 percent of …

Phytoplankton Dynamics Of Two Northern Prairie Lakes And Possible Relations To Dissolved Nutrients, Alan B. Hauber

Electronic Theses and Dissertations

Phytoplankton populations in Enemy Swim Lake were observed to be quite different. Although these lakes lie within the same geographic area (Coteau des Prairies), major differences in water quality were recorded. The differences in water quality were reflected in the phytoplankton populations and appeared to be influenced by the agricultural practices on the watersheds. Enemy Swim Lake was basically a diatom lake while Lake Herman contained mostly blue-green algae. Genera of algae found in Enemy Swim Lake were: Anabaena, Aphanizomenon, Lyngbya, Pediastrum, Staurastrum, Dinobyron, Asterionella, Fragilaria, Melosira, Stephanodiscus, and Ceratium. All of the above genera occurred in Lake Herman except …

A Clinico-Pathologic Study Of Botulism In Ring-Necked Pheasants, Hazel J. Shave

Electronic Theses and Dissertations

Toxins were produced from 6 strains of Cl. Botulinum, 2 of which killed pheasants. Inoculated birds were observed and a description of the progression of signs of the disease is given. Juvenile pheasants were inoculated with Types A and C toxin intramuscularly and were given the toxin orally. These birds were observed and their clinical signs noted. Adult pheasants were inoculated with toxoid prepared from type C toxin and commercial toxoid; injections were repeated in 21 days. Fourteen days following the final injection, the birds were challenged with toxin. Those protected with toxoid survived, while those receiving saline succumbed. Gross …

Responses Of Rumen Microflora To Whey Products Added To High-Grain Low-Roughage Rations, Virgil L. Metzger

Electronic Theses and Dissertations

Many factors present in livestock feeds affect the numbers and types of protozoa and bacteria in the rumen. A small particle size of feed and a fast rate of passage of the feed through the ruminant decreases protozoal numbers. Full feeding of a concentrate ration and an acid pH in the rumen also tend to reduce protozoa numbers. Bacteria numbers tend to increase as the protozoa numbers decrease. Knowledge of rumen microflora population changes on different rations is lacking. It is known that restricted-roughage rations will generally cause lower protozoal numbers. Since whey is an available source of lactose and …

The Lipid Composition Of Milk As Affected By High Grain-Limited Roughage Rations Containing Whey Products, Roger Charles Peper

Electronic Theses and Dissertations

Certain rations fed to lactating dairy cows appear to have a dramatic influence on the lipid composition of milk fat produced. A high grain ration fed with a limited amount of roughage tends to cause a depression in milk fat production while at the same time changing the milk fat composition. There have been various attempts to alleviate the depression in milk fat. Minerals used in the ration seem to slightly relieve the milk fat depression caused by high grain rations. One drawback has been lower milk production due to a decline in concentrate consumption. Whey products added to a …

Rapeseed, Sunflower And Soybean Meals As Protein Supplements In Dairy Calf Starters, Paul E. Stake

Electronic Theses and Dissertations

The world need for protein is ever-increasing causing the feed industry to seek new sources of protein supplementation for livestock (17). Urea and other non-protein-nitrogen (NPN) source have received much attention in the past twenty years as protein substitutes, but their use is limited to years as protein substitutes, but their use is limited to functional ruminant animals. Pre-ruminant calves, unable to utilize NPN, need natural protein in their diets. Soybean meal (SBN) has been the common protein supplement in many dry calf meals in the Midwest for several years and has been proven to be an acceptable source of …

Arboviruses In South Dakota Mosquitoes And Their Pathogenicity To Pheasants, Duane Robert Larson

Electronic Theses and Dissertations

The extent of arthropod-borne virus activity in humans and domestic and wild vertebrates in South Dakota is not known. The World Health Organization (88) defines an arbovirus as follows: "an arbovirus must produce a viremic in one or more vertebrate species, multiply in some arthropod that feeds on viremic blood and be transmitted through feeding." Mosquitoes or other arthropods fill these requirements because female mosquitoes take blood as a requisite to egg maturation. Blood from any vertebrate host contains the essential nutrients for ovarian maturation (65). Not all mosquitoes prefer blood from the same host so a wide variety of …

The Influence Of Phenobarbital, Diphenylhydantoin, Trimethadione And Ethosuximide On Rat Liver Demethylase Activity, Gerald L. Wannarka

Electronic Theses and Dissertations

Of the many anti-epileptic agents available, the most commonly used compounds can be divided into four categories: the barbiturates and related drugs, the hydantoins, the oxazolidines and the succinimides. Because of the possibility of concurrent use of the compounds in the treatment of epilepsy, it would be advantageous to have some information concerning the effect that each group has individually on microsomal enzyme systems before therapy in instituted. This information would enable the clinician to more adequately predict drug response thus reducing dosage regimen adjusting time and also possibly reducing the incidence of adverse reactions or interactions. The effect of …

Evaluation Of Orally Administered Sodium D-Thyroxine As A Teratogen In New Zealand White Rabbits, Gary A. Thibodeau

Electronic Theses and Dissertations

Sodium D-thyroxine was evaluated for possible embryotoxic and/or teratogenic effects following oral administration in New Zealand White rabbits. All animals utilized were alert, active and apparently disease-free virgin does weighing three and one-half to four kilograms. Rabbits were individually housed in stainless steel batteries and maintained on a commercially available palletized diet and mineral supplement. Feed and water were provided ad libitum in animal quarters air conditioned to minimize environmental temperature fluctuations. Following a 14-day post-delivery observation period does were bred to New Zealand White bucks and randomly allocated to one of two experimental groups or the control group each …

Effects Of Various Factors On The Rachitogenic Activity Of Isolated Soy Protein, Donald James Arshem

Electronic Theses and Dissertations

The nature of the rachitogenic activity of isolated soy protein was investigated in fifteen studies. A RP-100-glucose purified diet was fed to day-old turkey poults housed in stainless steel batteries. Feed and water were provided ad libitum. Corn, oat hulls, solvent-extracted soybean meal, full-fat extruded soybeans, C-1 protein, casein and texturized forms of soy protein were added to the basal diet at various levels. All feedstuffs were added at two particle sizes: natural form of the feedstuff (>250 u); and ground in a ball mill (<250 >u). The effects of autoclaving for 60 minutes at 120°C were also investigated. …

Effects Of Various Levels Of Dietary Selenium And Arsenic On Chickens, Richard L. Arnold

Electronic Theses and Dissertations

Various levels of selenium and arsenic additions were made to several types of chicken diets to study their effects on growth and reproduction criteria. Three experiments were conducted. The first study involved day-old chicks and terminated at 64 weeks of age. These yearling hens were then used for the second experiments which terminated when the hens were 104 weeks old. The third study was initiated with 20 week old pullets and terminated when they were 52 weeks old. Feeding purified diets resulted in slower chick growth and lower mature body weights of hens. Selenium additions of 2.0 ppm resulted in …

A Conceptual Analysis Of Alienation In Current Theory And Research, Lanny Aron Neider

Electronic Theses and Dissertations

The purpose of this study is to examine the assumed relationship between theory and research with respect to alienation. The basic hypothesis of this study is that empirical research on alienation would be influenced by existing theoretical formulations on the topic. It is argued that Melvin Seaman's 1959 conceptualization of alienation would constitute the major theoretical influence inasmuch as it alone provided a systematic set of research­able meanings. To test this basic hypothesis, four sub-hypotheses were developed: (1) Based upon Seeman's five dimensional scheme one should expect a fairly equal emphasis on the examination of all dimensions of alienation in …

Movements And Habitat Use By Hen Pheasants During Brood Rearing, Lynn E. Hanson

Electronic Theses and Dissertations

Land-use patterns characteristic of prime pheasant range in the Great Plains and prairie region have 50-75 percent of the land under cultivation according to Kimball et. al. (1956). Farmland is pheasant habitat, and the production of pheasants is therefore greatly influenced by farming practices. Considerable research has been done on rates of pheasant production, nest success, and cover preferences for nesting. However, little information has been obtained on movements and cover preferences for brood rearing. Most studies of the type of cover utilized by pheasant broods have been based on roadside and random field observations. Kozicky and Hendrickson (1951) carried …

The Influence Of Various Stress Conditions On Cholinesterase Levels Of Cattle Treated With An Organophosphorus Insecticide, Mitchell J. Wrich

Electronic Theses and Dissertations

Six-to 8-months-old Hereford heifers categorized as grubby or grub-free calves were used for this research. Forty calves were purchased in 1968 and also in 1969. The grubby calves were obtained from Highmore, South Dakota, an area where calves have a history of heavy grub infestations of both Hypoderma bovis (L.) and Hypoderma lineatum (de Villers). The grub-free calves were purchased in Fargo, North Dakota. Calves raised in this area seldom are infested with cattle grubs. Specified groups of calves were subjected to 30 minutes of continuous exercise or the withholding of feed and water for 24 hours prior to treatment …

An Evaluation Of An Aerated Lagoon System Treating Combined Dairy And Domestic Wastes During Summer Operation, Douglas M. Skie

Electronic Theses and Dissertations

The Water Quality Act of 1965 and the adoption of the subsequent state water quality standards emphasized the general public's concern for the control of water pollution; for it has become the goal of our nation to maintain all American waters in a suitable condition for domestic and industrial supply, for recreation and for other beneficial uses. It is for these reasons that many communities have been faced with the problem of constructing new sewage treatment facilities or expanding present operations. The use of stabilization ponds as a means of providing sewage treatment has been the practice of many small …

The Relationship Of Porcine Muscle Fiber Size And Number To Management, Meatiness And Quality, Ronald J. Smith

Electronic Theses and Dissertations

For many years animal scientists have been striving to find the “foolproof” method foreseeing the desired carcass and consumer characteristics in live animals before they are slaughtered. As a result, several different live animal and carcass evaluation techniques have been developed and tested with slow but encouraging success in some areas. This “never-ending” search has been stimulated by the development of new and more sophisticated research tools and facilities as time advances. Increasing consumer demands for a muscular, trim, high quality meat product makes identification of these desired traits in the live animal and carcass necessary. Thus, the producer, feeder …
