High Lysine Corn Fed Free-Choice To Growing-Finishing Swine, Richard C. Wahlstrom, George W. Libal
High Lysine Corn Fed Free-Choice To Growing-Finishing Swine, Richard C. Wahlstrom, George W. Libal
South Dakota Swine Field Day Proceedings and Research Reports, 1970
Analyses of opaque-2 corn have indicated a higher content of lysine and tryptophane than found in normal corn. Since these two amino acids are the most limiting amino acids in most practical swine diets, opaque-2 corn should permit a reduction in the need for supplementary protein. Experiments conducted at the South Dakota Agricultural Experiment Station and at other Experiment Stations have shown this to be true, with less protein supplement needed in swine rations containing opaque-2 corn than in rations containing normal corn.
Effect Of Environment, Sex And Protein Level Of Ration On Performance And Carcass Characteristics Of Growing-Finishing Swine, Richard C. Wahlstrom, George W. Libal, Jacob F. Fredrikson
Effect Of Environment, Sex And Protein Level Of Ration On Performance And Carcass Characteristics Of Growing-Finishing Swine, Richard C. Wahlstrom, George W. Libal, Jacob F. Fredrikson
South Dakota Swine Field Day Proceedings and Research Reports, 1970
Research conducted at the Southeast South Dakota Experiment Farm during the winter of 1968-69 and reported at the 1969 Swine Field Day (A.S. Series 69-38) indicated that the performance of pigs fed rations containing 15% protein to about 115 lb. and 12% protein to market weight was equal to that of pigs fed a ration 17% protein to 115 lb. reduced to 14% protein from 110 lb. to market weight. In the previous trial about 9% more feed was required for those pigs fed in the uncontrolled environment; however, rate of gain was not affected by the type of housing. …
Vitamin E, Copper, And Tylosin In The Diets Of Growing-Finishing Swine, George E. Libal, Richard C. Wahlstrom
Vitamin E, Copper, And Tylosin In The Diets Of Growing-Finishing Swine, George E. Libal, Richard C. Wahlstrom
South Dakota Swine Field Day Proceedings and Research Reports, 1970
Recent research with growing pigs has shown that vitamin E may be deficient in some corn-soybean meal diets. Some possible reasons why vitamin E deficiencies are being experienced today are that fewer pigs are fed on pasture, which is a good source of vitamin E; more corn is being picked wet and then artificially dried, which can destroy vitamin E; and the presence of a low selenium content of corn.
Copper has been shown to produce a growth response similar to antibiotics when it is fed at levels of 125 to 250 ppm. the study reported herein was conducted during …
Roasted Soybeans For Growing-Finishing Swine, Richard C. Wahlstrom, George W. Libal, Richard Berns
Roasted Soybeans For Growing-Finishing Swine, Richard C. Wahlstrom, George W. Libal, Richard Berns
South Dakota Swine Field Day Proceedings and Research Reports, 1970
Soybeans contain about 18% fat. In the past it has been economical to process the soybeans into soybean meal. Soybean meal is the major protein supplement fed to swine. The recent development of new equipment to cook soybeans on the farm has resulted in a renewed interest in the use of cooked soybeans in swine rations. The objectives of the study reported here were to compare the performance of pigs fed whole soybean meal and to study the effects of whole soybeans on the carcasses produced.
Influence Of Temporary Chemical Immobilization Of Boar Spermatozoa Upon In Vitro Survival, W. L. Singleton, T. D. Rich
Influence Of Temporary Chemical Immobilization Of Boar Spermatozoa Upon In Vitro Survival, W. L. Singleton, T. D. Rich
South Dakota Swine Field Day Proceedings and Research Reports, 1970
The use of artificial insemination (AI) in swine has been restricted because of the inability to store semen. It is usually recommended that for AI use boar semen not be stored more than 48 hours. Obviously, the goal is to develop a technique whereby boar semen could be stored indefinitely such as is the case with bull semen. However, until such a technique is developed, a method of storing boar semen for a few days would be of value for promoting AI in swine.

Protein And Lysine Levels In Growing-Finishing Swine Rations, R. C. Wahlstrom, G. W. Libal, J. F. Fredrikson
South Dakota Swine Field Day Proceedings and Research Reports, 1970
Cereal grains are particularly low in lysine, one of the essential amino acids, and a protein supplement must be fed with grains to supply additional lysine as well as other amino acids. The purpose of the experiment reported herein was to study the performance of growing and finishing pigs when fed rations of different protein content with and without additional lysine supplementation.

The objectives of the trial reported here were:
1. To compare the performance of pigs fed rations with the same proportions of grain and supplement but with the grain corn in one rations and wheat in another ration.
2. To assess the possible feeding value of wheat's greater protein content by use of an all wheat ration in which there was a lower level of supplemental protein.
3. To assess the value of lysine in wheat rations by the effition of lysine to the same ration as used for comparison 2 (above).

The Effect Of Gestation Energy Levels On Reproductive Performance Of Sows And Gilts, George W. Libal, Richard C. Wahlstrom
The Effect Of Gestation Energy Levels On Reproductive Performance Of Sows And Gilts, George W. Libal, Richard C. Wahlstrom
South Dakota Swine Field Day Proceedings and Research Reports, 1970
Restricting energy on total feed intake has been accepted as a desirable management pract ice for gestating sows and gilts. The advantages are reduced feed costs during gestation and larger and stronger litters resulting from more proper nutrition of the gestating sow. The common practice of reducing total feed level quite of ten reduces daily intake of energy protein and many of the other nutrients required by the sow. The experiment reported herein is an attempt to establish minimum required levels of metabolize energy for gestating sows and gilts under both summer and winter conditions. These sows will be maintained …
Review Of Research Of The Value Of High Moisture Corn For Growing And Finishing Swine, L. J. Kortan
Review Of Research Of The Value Of High Moisture Corn For Growing And Finishing Swine, L. J. Kortan
South Dakota Swine Field Day Proceedings and Research Reports, 1970
Work at South Dakota State University during the 10 year period 1942-1951 with soft corn for growing-finishing pigs showed that hogs are well adapted to utilize soft corn. In all six trials during this period, pigs fed soft corn showed a lower rate of gain per day than the pigs fed hard corn. However, when the soft corn was dried and fed, the pigs made practically the same rate of gain as the pigs fed hard corn. Compared on a dry matter basis, the value of soft corn was practically equal to hard corn for growing pigs. However, the pigs …

Feeding Stalls For Brood Sows, George W. Libal, Richard C. Wahlstrom, J. W. Mccarty
South Dakota Swine Field Day Proceedings and Research Reports, 1970
How to assure that each sow gets her fair share of feed and how to control the "boss" sows are management problems facing the producer who is limit feeding groups of sows in order to get maximum litter size and minimum gestation feed costs. Feeding stalls have proven very effective in achieving both of these objectives. There are several types of commercial stalls on the market as well as several good designs for homemade feeding stalls. The type used South Dakota State University has drawn considerable interest by producers and many have asked for material lists and costs. These stalls …
The Influence Of Energy During Estrus Of On Ovulation Rate, Goerge W. Libal, Richard C. Wahlstrom
The Influence Of Energy During Estrus Of On Ovulation Rate, Goerge W. Libal, Richard C. Wahlstrom
South Dakota Swine Field Day Proceedings and Research Reports, 1970
Recently, English workers have reported that when sows or gilts that were being limit fed (3 to 4 lb. per day) were allowed a double quantity of feed only on the first feed following breeding the number of ovum shed was increased. When sows were allowed to complete gestation, litter size was larger by approximately 2 pigs. The experiment reported herein was an attempt to duplicate the English work and evaluate this method of "flushing" under South Dakota conditions.

Some Factors Affecting The Growth Of Grain Elevators In South Dakota, Albert E. Raeder
Some Factors Affecting The Growth Of Grain Elevators In South Dakota, Albert E. Raeder
Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)
The grain elevator industry in South Dakota is currently undergoing considerable change. Small, inefficient elevators are being replaced with larger, more mechanized units. In South Dakota in 1960, there were 533 elevator companies in 368 towns but by 1968 only 450 elevator companies survived in 345 towns. An elevator company includes all the facilities and businesses that are under one management. Throughout this study elevator companies will be referred to as elevators. All of this points out that the industry is dynamic and changing. Some elevators keep up with these changes, while others fail to adopt new ideas. What are …

Abnormal Milk Evaluations In Eastern South Dakota Milk Plants And Dairy Herds, Edwin J. Kleen
Abnormal Milk Evaluations In Eastern South Dakota Milk Plants And Dairy Herds, Edwin J. Kleen
Electronic Theses and Dissertations
For many years bovine mastitis has been a major problem for dairy producers, the seriousness of which can be measured by the volumes of literature which have been written about it as well as the economic losses incurred by the dairy industry because of it. The fact that mastitis is still a virulent disease in spite of the vast amount of research conducted on it would suggest either that the underlying causes of mastitis still are not completely understood or that the knowledge gained through research has not been presented effectively to those who need it most—namely the dairy farmer. …
Flavor Preference And Stability Of A Low-Fat Dairy Spread, James Robert Miller
Flavor Preference And Stability Of A Low-Fat Dairy Spread, James Robert Miller
Electronic Theses and Dissertations
Low-fat dairy spread has been defined as a product which contains only dairy ingredients and has a lower fat content than the commonly used spreads, butter and margarine (5). Although some low-fat spreads have contained very little fat, most of those which have been developed during the past 30 years have contained about one-third to two-thirds as much fat as the commonly used spreads and have had a higher protein content. ·The low-fat dairy spread studied in this project contained about ten times more protein and only one-half as much fat as butter and margarine. The present day justification of …
Enhancement Of Foliar Penetration And Herbicide Activity By Oils, James F. Peacock
Enhancement Of Foliar Penetration And Herbicide Activity By Oils, James F. Peacock
Electronic Theses and Dissertations
To learn more about oils and how they affect post-emergence spray applications of herbicides, two major problem areas were investigated. The first dealt with specific physical and chemical properties of oils as they are associated with phytotoxicity and enhancement of herbicidal activity, while the second dealt with foliar penetration as a possible mechanism of enhancement. Simple correlation and multiple regression analyses were conducted for specific properties of mineral oils applied to green foxtail (Setaria verdis (L.) Beauv.) and grain sorghum (Sorghwn bicolor (L.) Moench. 'Northrup King 133') as 5% oil in water emulsions with and without 2.24 kg/ha of atrazine …
The Effect Of Harvesting And Storage Methods On Chemical Composition And In Vitro Digestibility Of First Cutting Alfalfa Hay, Perry A. Fales
The Effect Of Harvesting And Storage Methods On Chemical Composition And In Vitro Digestibility Of First Cutting Alfalfa Hay, Perry A. Fales
Electronic Theses and Dissertations
The importance of alfalfa hay in dairy cattle feeding is generally acknowledged. The reasons why alfalfa is used so extensively in dairy cattle rations are due to its high protein content, high acceptability by cattle, its wide ·area of adaptation, and high yields. A popular way of handling the forage is to put it up as hay. South Dakota produced 3,261,000 tons of alfalfa hay in 1968. There were 73 million tons of alfalfa hay produced in the United States during 1968 (10) making it a crop of major importance. Farming practices have changed considerably the last ten years. Among …
Effect Of Days Open On Lactation Production, Roger L. Ripley
Effect Of Days Open On Lactation Production, Roger L. Ripley
Electronic Theses and Dissertations
Accurate evaluation of dairy production records is essential if dairymen are to establish and maintain profitable dairy herds and efficient culling programs. Improper record evaluation may result in. saving breeding stock that otherwise might be eliminated. Many factors may influence the validity of individual production records. Adjustment factors, currently in use by the United States Department of Agriculture (USDA) for sire and cow evaluations, are generally accepted as removing the majority of these influences. Consequently, these factors are invaluable to practical dairymen. The adjustment factors, suggested by McDaniel, et al. (24) in 1967, take into account the geographical location, season …
