Optimum Movement Of Feeder Calves And Feed Grains Within South Dakota With Implications For Slaughter Plant Location, Valentine M. Heier Jan 1968

Optimum Movement Of Feeder Calves And Feed Grains Within South Dakota With Implications For Slaughter Plant Location, Valentine M. Heier

Electronic Theses and Dissertations

The basic economic activity in South Dakota is agriculture. Therefore, it is essential to the economic position of the state that information is made available which can serve as a guide in developing the agricultural industries within the state. The purpose of this study is to provide such information to the cattle feeding and beef slaughtering industries. Livestock data indicate that a large proportion of the cattle produced in South Dakota is shipped out of the state for fattening and slaughter. Data also indicate that the state is an exporter of feed grains. It seems that if these feeder cattle …

Chlorinated Hydrocarbon Residues In Pronghorn Antelope Antilocapra Americana Americana (Ord) 1815 Of South Dakota Collected In 1966, Gary L. Moore

Electronic Theses and Dissertations

Man’s primary concerns have always been the struggle for survival and improvement of his lot. As his numbers increased, he attained greater ability to manipulate his environment. One method of manipulation has been through the use of insecticides. One of the largest uses of insecticides has been in connection with pest control on agricultural lands. Pest control has become of great economical significance within the past decades. Since South Dakota is primarily as agricultural state it has been caught up in this bioeconomical problem. One control method used has been the use of chlorinated hydrocarbon insecticides. (see more in text)

Lipid Analysis Of Maturing Crambe Seed, Dwayne Walter Rehfeld Jan 1968

Lipid Analysis Of Maturing Crambe Seed, Dwayne Walter Rehfeld

Electronic Theses and Dissertations

For several years, plants have been screened in the search for compounds that might have a potential use in industry and which presently have no other suitable source (1). During a screening study, Mikolajczak et al. (2) found that crambe (common name for Crambe abyssinica) contained a high percentage of erucic acid. Erucic acid has many potential industrial uses and is currently being obtained from imported rapeseed (J). Because there is presently no suitable domestic source of erucic acid, crambe is a potential new crop for the United States. Field studies of crambe have shown that the seeds tend to …

Ultrasonic Evaluation Of Swine, Lowell M. Anderson Jan 1968

Ultrasonic Evaluation Of Swine, Lowell M. Anderson

Electronic Theses and Dissertations

Current meat consumption patterns and competition from other meats and meat substitutes present a challenge to today’s pork producer to produce a higher quality product with a larger lean to fat ratio. One avenue or approach toward meeting the challenge could be through selection of superior breeding animals. Thus the major challenge at the producer level is that of accurately determining the meatiest individuals for replacements. Historically man has relied upon the visual appraisal, however, few of the live animal. Therefore, the majority must depend upon selection aids. Actual carcass cut-out data can be obtained, but this results in the …

An Analysis Of Stephen Leacock's Treatment Of The Detective Story, Beverly Lamb Jan 1968

An Analysis Of Stephen Leacock's Treatment Of The Detective Story, Beverly Lamb

Electronic Theses and Dissertations

On any list of Canadian writers, Stephen Leacock's name would have to appear at the top because of his achievements in humor. He has won for himself a unique place in the Canadian scene as economist, historian, critic, essayist, lecturer, and teacher, but above all, as a writer and speaker who is the incarnation of humor. Born in the south of England, at Swanmoor in Hampshire on December 30, 1869, he moved, in 1876, with his family to Canada. For some time he had a tutor for his schooling but when his father left the family, Stephen was sent to …

The Influence Of Sodium Phenobarbital On The Hepatic Microsomal Enzyme System Which Reduces P-Nitobenzoic Acid In Fetal And Newborn Rats, Robert James Neumayr Jan 1968

The Influence Of Sodium Phenobarbital On The Hepatic Microsomal Enzyme System Which Reduces P-Nitobenzoic Acid In Fetal And Newborn Rats, Robert James Neumayr

Electronic Theses and Dissertations

The duration and intensity of action of many drugs are largely determined by the speed at which they are metabolized in the body by enzymes in liver microsomes (1). Previous studies have shown that the activities of drug metabolizing enzymes in liver microsomes are markedly increased when animals are given various drugs, hormones, insecticides, and carcinogens. This increase in activity appears to represent an increased concentration of enzyme protein and is referred to as enzyme induction. Induction of liver microsomal enzymes leads to an accelerated biotransformation of drugs in vivo. This results in an· altered duration and intensity of drug …

Lysine And Protein Supplementation Of Barley Rations For Growing-Finishing Swine, J.W. Mccarty, R.C. Wahlstrom, Albert Dittman Nov 1967

Lysine And Protein Supplementation Of Barley Rations For Growing-Finishing Swine, J.W. Mccarty, R.C. Wahlstrom, Albert Dittman

South Dakota Swine Field Day Proceedings and Research Reports, 1967

Barley is an important crop for north central South Dakota. It is higher in protein content than corn, ranging from 11 to 15 percent. However, it is lacking in adequate quantities of the amino acid lysine to support normal growth of growing-finishing pigs. A series of trials have been conducted at the North Central Substation, Eureka, using barley as the only grain in rations for growing-finishing swine. These trials have indicated a moderate improvement in gain and feed efficiency when barley-soybean me al rations have been supplemented with lysine. The objective of the experiment reported herein was to study the …

Energy Needs Of Gilts And Sows During Gestation, C.S. German, R.W. Seerley, R.C. Wahlstrom Nov 1967

Energy Needs Of Gilts And Sows During Gestation, C.S. German, R.W. Seerley, R.C. Wahlstrom

South Dakota Swine Field Day Proceedings and Research Reports, 1967

During the past few years several experiments have demonstrated that gilts and sows do not need to be fed as liberally during the gestation period as was previously recommended. Overfeeding of the pregnant sow is not only an uneconomical practice but also can lead to difficulties at farrowing time and more pigs overlaid if sows are excessively fat. Most experiments with feeding methods for pregnant gilts have limited the intake of all nutrients. The purpose of this study reported here was to determine the effect of restricting only the energy intake.

Reproductive Performance Of Gilts And Sows Fed Daily, Twice Weekly Or Weekly During Gestation, J.W. Mccarty, R.W. Seerly Nov 1967

Reproductive Performance Of Gilts And Sows Fed Daily, Twice Weekly Or Weekly During Gestation, J.W. Mccarty, R.W. Seerly

South Dakota Swine Field Day Proceedings and Research Reports, 1967

Feed management for gestating gilts and sows and the effect on performance and production costs has been the subject of considerable research in recent years. The object of these studies has been to cut production costs without adversely affecting sow performance in terms of pig numbers and weights at farrowing and weaning. Bred females have been satisfactorily managed with as little as three pounds of feed per head daily for part of the gestation period. Management which avoids hand feeding by giving sows access to a self-feeder for periods such as every third day has not consistently resulted in important …

Dehydrated Alfalfa Meal In Growing-Finishing Swine Rations, L.M. Anderson, R.W. Seerley, R.C. Wahlstrom Nov 1967

Dehydrated Alfalfa Meal In Growing-Finishing Swine Rations, L.M. Anderson, R.W. Seerley, R.C. Wahlstrom

South Dakota Swine Field Day Proceedings and Research Reports, 1967

It has been suggested by many investigations that certain ingredients contain unidentified growth factors of bene fit to the growing pig. One of the ingredients that has been suggested as a source of unidentified growth factors is alfalfa meal. This trial was part of a larger experiment participated in by several states in the North Central region. The objectives were to determine the effects of low levels of dehydrated alfalfa meal in a com-soybean meal type ration fed to growing-finishing swine.

The Influence Of Alfalfa Coumestrol On The Reproductive Performance Of Gilts, R.H. Anderson, D.R. Shelby, R.W. Seerley, G.M. Loper

South Dakota Swine Field Day Proceedings and Research Reports, 1967

In Australia during the early 1940'sa syndrome known as "clover disease" was observed in sheep grazing subterranean clover. This syndrome was characterized by a marked reduction in fertility which was later proved to be due to a high content of estrogenic substances in the clover. Alfalfa has since been shown to contain varying levels of these plant estrogens. The most important of the plant estrogens present in alfalfa is coumestrol because of its relatively greater biological potency than the other plant estrogens and because of its more frequent occurrence. Plant physiologists have shown that alfalfa infected with certain fungus diseases …

Fish Solubles In Rations For Early Weaned Pigs, L.M. Anderson, R.W. Seerley, R.C. Wahlstrom Nov 1967

Fish Solubles In Rations For Early Weaned Pigs, L.M. Anderson, R.W. Seerley, R.C. Wahlstrom

South Dakota Swine Field Day Proceedings and Research Reports, 1967

This experiment was a continuation of a project covering several aspects of the nutrition of young pigs. The results of previous work reported at the 1966 Swine Field Day ( A.S. Series 66-21) showed that a simple corn-soybean meal fortified ration was equal to a more complex diet that also contained rolled oats, dried skim milk and sugar. Therefore, the current experiment was designed to compare a basal corn-soybean meal type ration with a similar ration containing 3% fish solubles. Fish solubles are a good source of high quality protein and also may contain an identified growth factor(s). The experiment …

Influence Of The Boar On Litter Size, D.R. Shelby Nov 1967

Influence Of The Boar On Litter Size, D.R. Shelby

South Dakota Swine Field Day Proceedings and Research Reports, 1967

Although the role of the boar in achieving a high conception rate among sows in a herd has long been recognized, the sow has gene rally been considered to be solely responsible for litter size. Litter size is determined by (l) the number of eggs ovulated, (2) the quality of eggs ovulated as evidenced by the ability of the eggs to be fertilized and develop into normal embryos, (3) the ability of the uterus to provide the proper environment for implantation and the development of normal embryos during pregnancy and (4) the number and quality of sperm received by the …

A Comparsion Of Three Methods Of Iron Administration In Preventing Baby Pig Anemia, R.D. Magstadt, R.W. Seerley, R.C. Wahlstrom Nov 1967

A Comparsion Of Three Methods Of Iron Administration In Preventing Baby Pig Anemia, R.D. Magstadt, R.W. Seerley, R.C. Wahlstrom

South Dakota Swine Field Day Proceedings and Research Reports, 1967

Baby pig anemia is a serious nutritional disease. It is primarily due to a lack of iron in the diet of the young pig. Pigs are born with very little stores of iron in their bodies. Also, sow' s milk does not contain enough iron to meet the pig' s requirements. Therefore young pigs which subsist on milk alone commonly become anemic at about three weeks of age. The fastest growing pigs are the first to show symptoms because they require more of this essential nutrient. Symptoms of anemia are: (1) respiratory difficulties shown by thumping of sides1 (2) paleness …

Relationship Of Some Semen Characteristics Of The Boar To Fecundity Of The Sow, W.L. Singleton, D.R. Shelby Nov 1967

Relationship Of Some Semen Characteristics Of The Boar To Fecundity Of The Sow, W.L. Singleton, D.R. Shelby

South Dakota Swine Field Day Proceedings and Research Reports, 1967

As the price-cost squeeze be comes more critical to the pork producer, every fact or which affects net profit must be critically weighed. The profit making potential of a swine herd increases directly with an increase in the number of live offspring produced per sow. The production of large litters is dependent on high fertility in both the sow and the boar. The fertility of boars will vary from complete sterility to high fertility . An actual breeding test is the only highly reliable method of those used to measure fertility level in the boar, but boars of complete sterility …

Supplemental Lysine In Drinking Water Of Growing-Finishing Swine Fed Rations Of Two Different Protein Levels, A.R. Taylor, R.W. Seerley, R.D. Magstadt, R.C. Wahlstrom Nov 1967

Supplemental Lysine In Drinking Water Of Growing-Finishing Swine Fed Rations Of Two Different Protein Levels, A.R. Taylor, R.W. Seerley, R.D. Magstadt, R.C. Wahlstrom

South Dakota Swine Field Day Proceedings and Research Reports, 1967

Cereal grains do not contain an adequate amount of the amino acids (protein building blocks) to support optimum growth of growing-finishing pigs. The protein present in cereal grains is of relatively "poor quality" since it does not contain the proper balance of amino acids to support optimum growth of growing-finishing swine. The most limiting amino acid in cereal grains is lysine. Protein supplements such as soybean meal, contain larger amounts of the essential amino acids and thus are used to balance a cereal grain ration. Previous research at this station, however, has shown that a corn-soybean meal ration can often …

Supplemental Lysine In Feed And Water For Growing-Finishing Swine, A.R. Taylor, R.C. Wahlstrom

South Dakota Swine Field Day Proceedings and Research Reports, 1967

At the 1966 South Dakota Swine Field Day information was reported (A.S. Series 6 6-22) on the effects of lysine in feed and water at comparable levels when the level of crude protein was slightly lower than normally recommended for the respective weight of the pigs. It was reported that pigs receiving lysine in the water gained slightly faster and considerably more efficiently than pigs that did not receive lysine or those fed lysine in the feed. In order to obtain more data on the effect of lysine in the feed or water for young pigs the experiment was repeated …

Adaptation Of Ultrasonics In The Selection Program, L.M. Anderson, L.J. Kortan, R.C. Wahlstrom

South Dakota Swine Field Day Proceedings and Research Reports, 1967

A useful selection tool available to swine producers in recent years has been the ultrasonic animal tester, more commonly called the Sonoray. In creasing numbers of swine producers across the nation have adapted the sonoray to their selection programs in an attempt to more accurately evaluate breeding herd replacements. This report is intended to demonstrate ways that a South Dakota swine producer could use the sonoray in a selection program for total herd improvement. The use of the sonoray could aid the purebred producer in three ways. Number one, the sonoray could be used to select the best gilts after …
