Chemical Weed Control In Pasture, Range And Hayland, Cooperative Extension South Dakota State University
SDSU Extension Fact Sheets
There are 28 million acres of pastures and rangeland, 2 million acres of native hayland, 2¼ million acres of alfalfa and ½ million acres of tame grass hayland in South Dakota. Many herbaceous and woody plants are present in these grassland areas. Some forbs add to the productivity and are desirable plants. Some may be desirable when found in sparse stands, but become undesirable in heavy stand intensities. Undesirable plants may reduce production of palatable forage, others may reduce the quality of animal products and still others may be poisonous to livestock.

Effects Of Aldrin On Young Pheasants Under Semi-Natural Conditions, Ronald Eugene Thill
Effects Of Aldrin On Young Pheasants Under Semi-Natural Conditions, Ronald Eugene Thill
Electronic Theses and Dissertations
Effects of aldrin on young pheasants were studied under semi-natural conditions in four one-acre enclosures during the summer of 1968. The center two-thirds of each plot was planted in corn; remaining peripheral cover was maintained in smooth brome and alfalfa. Prior to planting, center portions of two plots were sprayed with 2 pounds of aldrin per acre on Hay 20, while remaining plots served as controls. On June 12, four family units consisting of two broody pheasant hens and two bantam hens with 15 three-day-old chicks each were confined in plots. Hens and broods were given free run 10 days …
A Comparison Of Cheese Yields Produced From Normal And Abnormal Milk, Raymond L. Rennich
A Comparison Of Cheese Yields Produced From Normal And Abnormal Milk, Raymond L. Rennich
Electronic Theses and Dissertations
Mastitis has long been a problem to the Dairy Industry. All milk constituents are affected. Abnormal milk usually has a slightly higher total nitrogen and a lower casein content than does normal milk. Since the percent casein is believed to have the greatest influence on the yield of cheese, it is postulated a lower casein content in milk will produce a proportionately smaller amount of cheese for a given volume of milk. Cheese factories presently buy milk on the basis of fat percentage and weight with no regard to the amount of total protein or casein present. Therefore, it would …
Vitamin A In Beef Cattle Feeding, L.B. Embry, L.J. Kortan
Vitamin A In Beef Cattle Feeding, L.B. Embry, L.J. Kortan
Agricultural Experiment Station Animal Husbandry Pamphlets
Vitamin A is essential for all cattle. The vitamin does not occur naturally in feeds of plant origin. Many cattle are never fed vitamin A as such but do not develop a deficiency of the vitamin. The reason for this is that many feeds (pasture, good quality hay, silage, and yellow com) furnish carotene which is converted to vitamin A in the animal body.
Ecological And Trophic Distribution Of Pesticides In Lack Poinsett, South Dakota, Michael Robert Hannon
Ecological And Trophic Distribution Of Pesticides In Lack Poinsett, South Dakota, Michael Robert Hannon
Electronic Theses and Dissertations
Ecological and trophic distributions of chlorinated hydrocarbon residues in Lake Poinsett, South Dakota were studies. Components of the ecosystem analyzed were water, bottom sediment, zooplankton, benthic algae, crayfish, aquatic insects and fish. Concentrations of aldrin, DDD, DDE, DDT, dieldrin, endrin, heptachlor, heptachlor epoxide, lindane, methoxychlor, and toxaphene were determined by gas chromatography and thin-layer chromatography. DDT and its metabolites, DDD and DDE, were the highest residues detected in all trophic levels examined. Heptachlor, heptachlor epoxide, aldrine, dieldrin, and lindane were present in the majority of sample types, while neither endrin nor methoxyshlor was detected above analytical confidence limits in any …
Corn Rootworm Control In South Dakota With Notes On Wireworm And Cutworm Control, Cooperative Extension South Dakota State University
Corn Rootworm Control In South Dakota With Notes On Wireworm And Cutworm Control, Cooperative Extension South Dakota State University
SDSU Extension Fact Sheets
Resistant strains of the western corn rootworm are a serious insect problem in South Dakota. The western, northern, and southern species have been present for a number of years. However, the first evidence of resistant strains of western corn rootworm in South Dakota were observed in 1962. Treatment failures using aldrin and heptachlor, later checked by laboratory tests on adult beetles, indicated that the western corn rootworm population in Lincoln County in southeastern South Dakota was becoming resistant.
Livestock Marketing In The Upper Missouri River Basin Part Ii: The Sioux City Stockyards-Facilities And Costs Of Operation, M. J. Powers, D. R. Bendt
Livestock Marketing In The Upper Missouri River Basin Part Ii: The Sioux City Stockyards-Facilities And Costs Of Operation, M. J. Powers, D. R. Bendt
Research Bulletins of the South Dakota Agricultural Experiment Station (1887-2011)
This study was not intended to suggest that the Sioux City Stockyards is unique among stockyards in being affected by changes in the livestock marketing system. Rather, it is probable that the Sioux City Stockyards is a typical example of how these changes have affected the terminals in general. Thus, the implications of this study have application to more than just the Sioux City Stockyards.

Livestock Marketing In The Upper Missouri River Basin Part Iii: Cost-Volume Relationships Of Commission Firms, M. J. Powers, D. R. Bendt
Research Bulletins of the South Dakota Agricultural Experiment Station (1887-2011)
This study is concerned with determining the costs of operating various size commission firms at the Sioux City Terminal Stockyards.
The Sioux City Terminal Stockyards is located in Sioux City, Iowa, at the confluence of the Missouri and Floyd Rivers. It was established in 1893 when the Union Stockyards Company of Sioux City purchased the Central Stock Yard Company of Sioux City. The Sioux City Terminal Stockyards, like most terminal markets, has been experiencing a declining volume of business. Most of this decline can be attributed to technological ·improvements in transportation, refrigeration, and communications. These improvements enabled packing plants to …

Combining Barley And Oats For Growing-Finishing Gilts, J.W. Mccarty, Richard C. Wahlstrom, Albert Dittman
Combining Barley And Oats For Growing-Finishing Gilts, J.W. Mccarty, Richard C. Wahlstrom, Albert Dittman
South Dakota Swine Field Day Proceedings and Research Reports, 1968
Northcentral South Dakota is an area in which corn is not produced in sufficient quantity for livestock feed needs. Since barley and oats are also produced in the area, both are used singly or in combination for swine production. Work at the Northcentral Substation, Eureka, has demonstrated that properly supplemented all- barley rations support rapid growth and efficient gains for swine. Because of interest in the area in using oats also for swine rations this trial was designed to compare barley alone with combinations of barley and oats.
Estrus Synchronization And Artificial Insemination Of Swine, D.R. Shelby
Estrus Synchronization And Artificial Insemination Of Swine, D.R. Shelby
South Dakota Swine Field Day Proceedings and Research Reports, 1968
For years scientists have been trying to find drugs or hormones that will control the reproductive cycle and bring gilts into estrus together to be bred at the same time. The only compound tested to date which has been successful in achieving this goal without also producing undesirable side effects is one called by the tradename Aimax. During a normal estrous cycle, gonadotropic hormones are released from the pituitary gland and are carried by the blood to the ovary where these hormones stimulate the production of estrogen by the ovary and cause ovulation. When Aimax is fed to female swine, …
Calcium And Phosphorus Levels In Rations For Growing-Finishing Swine, Richard C. Wahlstrom, Larry De Goey
Calcium And Phosphorus Levels In Rations For Growing-Finishing Swine, Richard C. Wahlstrom, Larry De Goey
South Dakota Swine Field Day Proceedings and Research Reports, 1968
Calcium and phosphorus have long been recognized as mineral elements that are seriously deficient in cereal grains and plant by-products. However, some questions arise as to the availability of these minerals, particularly phosphorus, in cereal grains and by-products and the requirements of swine for these minerals. Evidence of lameness of growing-finishing swine is often associated with a calcium or phosphorus problem in the ration although these minerals may or may not be a factor related to this condition. This experiment was conducted to study the effects of com-soybean meal rations containing varying levels of added calcium and phosphorus on growth …
Rations For Early Weaned Pigs, Richard C. Wahlstrom, Donald Mordhorst
Rations For Early Weaned Pigs, Richard C. Wahlstrom, Donald Mordhorst
South Dakota Swine Field Day Proceedings and Research Reports, 1968
One of the most critical times in the nutrition of the pig is during the first few weeks after weaning. This is particularly true if the pigs are weaned at an age of 3 to 4 weeks or younger. During the past two years an experiment has been in progress at this station to study different ration ingredients in rations for pigs weaned at about 3 weeks of age in order to determine if more economical rations can be developed that will be highly palatable and support rate and efficiency of gains comparable or superior to more complex rations. The …
Supplemental Lysine In Feed Or Water For Early Weaned Pigs, Richard C. Wahlstrom, Aaron R. Taylor
Supplemental Lysine In Feed Or Water For Early Weaned Pigs, Richard C. Wahlstrom, Aaron R. Taylor
South Dakota Swine Field Day Proceedings and Research Reports, 1968
Previous work at this and other experiment stations has shown that many practical swine rations may be deficient in the amino acid lysine. This is particularly true of rations that may be somewhat low in protein for the younger pig since protein or amino acid requirements are higher during the early growth period. Last year it was reported here (A.S. Series 67-27) that pigs weaned at three weeks of age and fed rations minimal in protein content gained faster and more efficiently when lysine was added to the water or feed. The experiment reported herein was an attempt to confirm …
Spectinomycin - A New Antibiotic, Richard C. Wahlstrom
Spectinomycin - A New Antibiotic, Richard C. Wahlstrom
South Dakota Swine Field Day Proceedings and Research Reports, 1968
Antibiotics have become standard ingredients in most rations for growing swine. Antibiotic feeding generally increases average daily gains, improves feed efficiency, improves uniformity of performance and may reduce death loss during the growing period. The exact method by which antibiotics cause these beneficial effects is not known. However, they apparently do have an influence on the intestinal bacteria and there is concern that the bacteria may become resistant to an antibiotic when fed continually. Therefore, new antibiotics must be evaluated and compared with existing effective antibiotics.
Effect Of A Controlled Environment On The Performance Of (1) Heavy And Light Weight Pigs And (2) Barrows And Gilts, Richard C. Wahlstrom, J.F. Fredrikson
Effect Of A Controlled Environment On The Performance Of (1) Heavy And Light Weight Pigs And (2) Barrows And Gilts, Richard C. Wahlstrom, J.F. Fredrikson
South Dakota Swine Field Day Proceedings and Research Reports, 1968
The trend in swine housing during recent years has been toward controlled environment buildings. These buildings generally contain slotted or partially slotted floors. Labor requirements in structures of this type are apt to be less than with conventional type buildings. Also of concern to the pork producer is the performance of growing-finishing pigs in these buildings compared to the performance in less costly structures. The purpose of the experiment reported herein was to study the performance of heavy and light weight pigs and also of barrows and gilts allotted separately when housed in different environmental conditions during December, January, and …
A Study Of Distillers By-Products In Growing-Finishing Swine Rations, Richard C. Wahlstrom, Craig German
A Study Of Distillers By-Products In Growing-Finishing Swine Rations, Richard C. Wahlstrom, Craig German
South Dakota Swine Field Day Proceedings and Research Reports, 1968
Several by-products of the distillery, fish and cheese industries have been reported to give growth responses when added to swine rations thought to be adequate in known nutrients. It is known that these by-product feeds are good sources of many vitamins and minerals and it has been postulated that they may contain other "Unidentified Growth Factors" (UGF) that may be required by the pig. The experiments reported herein were conducted to study the effect of distillers dried grains with solubles (DDG/S) on ration digestibility as well as its effect on growth and feed conversion of growing -finishing swine.

Optimum Shipment Patterns Of Feeder Cattle And Feed Grains In South Dakota And Their Implications, Mark J. Powers, Val Heier
Optimum Shipment Patterns Of Feeder Cattle And Feed Grains In South Dakota And Their Implications, Mark J. Powers, Val Heier
SDSU Extension Circulars
Current data on the livestock and grain industries of South Dakota indicate that the state is a net exporter of feeder cattle and feed grains, suggesting that if the feeder cattle and feed grains were retained within the state, the state’s beef feeding and packing industries could be expanded considerably. This study divided the state into seven regions based on their natural resource similarities to determine the optimum movement of feed grains and feeder cattle in South Dakota.

Since there is a limit to what can be paid for a feeder pig and still make a profit on the feeding program, the producer should carefully consider expected costs and returns before buying.
Forage Nitrate Poisoning (A Summary), Cooperative Extension South Dakota State University
Forage Nitrate Poisoning (A Summary), Cooperative Extension South Dakota State University
SDSU Extension Fact Sheets
Occasionally forages accumulate nitrates in quantities that are toxic to some farm animals. As long ago as 1895, the literature reported cases of this. In the 1930's heavy cattle losses from what was then termed "oat hay poisoning" were reported in the Great Plains and Rocky Mountain areas. These losses were found to result from the high nitrate content of the hay. It has now been well established that several forage plants and weeds accumulate nitrates in toxic amounts under certain soil and environmental conditions.
