Effect Of Sodium Selenite Levels On Tissue And Blood Composition And Performance Of Growing-Finishing Swine, T. B. Goehring, G. W. Libal, I. S. Palmer, O. E. Olson
South Dakota Swine Field Day Proceedings and Research Reports, 1982
A second trial was conducted to further study the problem of selenium toxicity. In this experiment, sodium selenite was utilized as the selenium source. The FDA has approved sodium selenite and sodium selenate supplementation of pig starter diets up to a level of .3 parts per million (ppm) of selenium. The study reported herein was conducted to determine the effect of sodium selenite levels on tissue and blood composition and performance of growing-finishing swine.

Effects Of Various Levels Of Sunflower Seeds On Growing-Finishing Swine, A. D. Hartman, R. C. Wahlstrom, G. W. Libal
South Dakota Swine Field Day Proceedings and Research Reports, 1982
Sunflowers are becoming a very important crop in South Dakota. Currently, most seeds are used to produce confectionary seeds or sunflower oil and sunflower meal. For various reasons, some sunflower seeds may not be suitable for these purposes. Feeding these seeds to livestock is one possible way to utilize them. Although at the present time sunflower seeds are not considered an economically feasible feed ingredient, prices may change, making them a more practical substitute for the common feed grains. For these reasons, this study has been conducted to determine growth and carcass characteristics of swine fed diets containing various levels …
Supplemental Potassium In Swine Diets Varying In Lysine Content, R. C. Wahlstrom, G. W. Libal
Supplemental Potassium In Swine Diets Varying In Lysine Content, R. C. Wahlstrom, G. W. Libal
South Dakota Swine Field Day Proceedings and Research Reports, 1982
Practical type swine diets contain levels of potassium in excess of National Research Council recommendations for this nutrient. However, it has been shown that potassium salts of metabolizable organic acids improved gain and efficiency of pigs fed low lysine diets. Previous work at this station indicated that .4 or .8% of supplementary potassium, from potassium chloride, did not affect performance of young pigs fed a diet containing .85% lysine. These pigs did respond to lysine supplementation, indicating that the .85% lysine level was not sufficient for maximum performance. The supplemental potassium appeared to decrease lysine concentration in the blood plasma …
Trace Mineral Supplementation Of Diets For Growing-Finishing Swine, R. C. Wahlstrom, G. W. Libal
Trace Mineral Supplementation Of Diets For Growing-Finishing Swine, R. C. Wahlstrom, G. W. Libal
South Dakota Swine Field Day Proceedings and Research Reports, 1982
Until the past few years, most diets for growing-finishing swine contained .5% salt. However, recent research has confirmed that a level of .2 to .25% added salt will meet the dietary sodium and chlorine requirements of the growing-finishing pig fed a grain-soybean meal diet. Some producers rely on trace mineral salt to supply the needed trace minerals to the diet. A reduction in the amount of trace mineral salt added to the diet from .5 to .25% results in only half as much of each of the trace minerals supplemented to the diet.
The study reported herein was designed to …
Sunflower Meal In Diets Of Growing-Finishing Pigs, G. W. Libal, R. C. Wahlstrom, Roland Hanson
Sunflower Meal In Diets Of Growing-Finishing Pigs, G. W. Libal, R. C. Wahlstrom, Roland Hanson
South Dakota Swine Field Day Proceedings and Research Reports, 1982
Sunflower meal, a by-product of the sunflower oil industry, has become increasingly available as a livestock supplement in recent years. Although lower in protein and lysine than soybean meal, an economic advantage for sunflower meal may exist on a cost per unit of lysine or protein basis. Using synthetic lysine and sunflower meal as feed ingredients, diets can be formulated which are equal in protein and lysine to corn-soybean meal diets. The study reported herein was designed to evaluate substituting sunflower meal for soybean meal in growing-finishing pig diets.
Protein Needs Of Barrows And Gilts 75 To 225 Pounds, R. C. Wahlstrom, G. W. Libal
Protein Needs Of Barrows And Gilts 75 To 225 Pounds, R. C. Wahlstrom, G. W. Libal
South Dakota Swine Field Day Proceedings and Research Reports, 1982
Although a considerable amount of research has been conducted on the protein requirement of growing-finishing barrows and gilts, there is still a discrepancy in the recommendations given. Most research has been conducted by feeding barrows and gilts together. Data have suggested gilts require more dietary protein than barrows.
This experiment was part of a regional project of the North Central Swine Nutrition Committee. The objective of the study was to determine the difference in the protein requirement between barrows and gilts.
Effect Of Varying Dietary Selenium Levels On Tissue Composition, Blood Composition And Performance Of Growing Swine Fed Seleniferous Grains, T. B. Goehring, G. W. Libal, I. S. Palmer, I. S. Palmer
Effect Of Varying Dietary Selenium Levels On Tissue Composition, Blood Composition And Performance Of Growing Swine Fed Seleniferous Grains, T. B. Goehring, G. W. Libal, I. S. Palmer, I. S. Palmer
South Dakota Swine Field Day Proceedings and Research Reports, 1982
It is established that selenium is an essential micronutrient as well as a natural toxicant for domestic livestock. However, reports of selenium toxicosis in swine are limited and not well documented. The level at which selenium becomes toxic to swine is thought to be about 8 ppm. This value was derived from the initial selenium research of the 1930's, with considerable extrapolation from other species used in this determination.
Since that time, diet composition has become much more complex, nutrient level of diets has increased and feed additives are commonly used. It is not known what effect these factors or …
Effect On Antibiotics In High Fiber Diets On Performance Of Growing-Finishing Pigs, G. W. Libal, R. C. Wahlstrom, T. B. Goehring, A. D. Hartman
Effect On Antibiotics In High Fiber Diets On Performance Of Growing-Finishing Pigs, G. W. Libal, R. C. Wahlstrom, T. B. Goehring, A. D. Hartman
South Dakota Swine Field Day Proceedings and Research Reports, 1982
The majority of the pigs in the Upper Midwest are fed a corn-soybean meal base diet. However, alternative feed ingredients are widely used in some regions. The lower performance, daily gain and efficiency of gain that is sometimes observed when other ingredients are used is often associated with higher fiber content of the diet. The pig has little ability to utilize fibrous materials in the stomach and small intestine where most digestion of feed and absorption of nutrients take place. Microorganisms present in the cecum and large intestine do break down fiber to usable products, but it is assumed that …

Sunflowers For Growing Pullets, Ali B. Kashani, C. Wendell Carlson
South Dakota Poultry Field Day Proceedings and Research Reports, 1982
South Dakota is the third leading state in the production of sunflowers. Although the primary use of this crop is for extraction of oil, its protein and other nutrient contents make it a suitable ingredient in poultry feed formulation. Growing pullets have been shown (A.S. Series 78-2, POULTRY 80-7) to have relatively low requirements for protein (12% of diet) and also to withstand relatively high fiber contents with no adverse effect on later performance. These characteristics make pullets (10 to 20 weeks of age) appropriate subjects for feeding high levels of full-fat sunflower seeds in their diets.

The $7 billion gross income for poultry, with the exception of the broiler chicken industry, is shared by nearly every state in the Union. Total farm income for 1977 (broilers, eggs, turkeys) showed an increase to $7.2 billion, but a regional breakdown was not available (USDA Agr. Sta., 1977). Even though many of the components for integrated pest management in poultry production are known, more specific knowledge of how best to utilize these components is needed.

Antibiotics have generally been more effective in counteracting, somewhat at least, the growth depression caused by feeding diets containing lower density cereal grains. However, growth responses have not been as consistent using other types of diets. In spite of extensive studies on the subject of antibiotics, their exact mechanism of action is yet to be clearly understood. Several factors have been shown to interfere with the intestinal absorption of these compounds for therapeutic purposes. Among these, calcium level and source have been shown to influence the blood level of tetracyclines.

A previous study (POULTRY 81-6) had shown that hens on diets utilizing sunflower meal as the major protein source supported fair egg production, whereas meat and bone meal as the major protein source supported substandard performance. Hen-day egg production was 15% poorer and feed intake was off by 22 grams per day averaged for all groups on the meat and bone meal diets.

It is generally recognized that birds do not have an enzyme in their digestive fluid which digests cellulose. However, cellulosic materials are major renewable resources available in large quantities which need to be properly utilized to help meet our needs for energy, chemicals, food and feed for a long-range solution. A variety of lignocellulosic materials containing acid-detergent fibers, are available and microorganisms capable of degrading either one or more of the three main constituents, viz., cellulose, hemicelluose and lignin, have been studied. A further variety of strategies are being explored, including thermal methods of degradation such as pyrolysis or biological …

The Effect Of Firm Pellets On Turkey Performance, M. Hassibi, C. W. Carlson, R. M. Luther
South Dakota Poultry Field Day Proceedings and Research Reports, 1982
Pelleting feeds has been shown to improve feed conversion up to 15% for livestock and poultry, but the processing techniques seem to be much more of an art than a science; Little information is available in the literature regarding techniques for obtaining firm pellets with the kind of stability that can resist the handling process.

The use of feed additives is a common practice for almost all species of animals raised under man's control. Addition of 60 ppm copper as copper sulfate to turkey diets improved growth rate to 8 weeks of age when low protein diets were used (POULTRY 81-2). This level of copper (60 ppm) along with Neo-Terramycin and Bacitracin was used in a factorial experiment to compare copper (Cu) and these two antibiotic supplements on the growth rate of turkeys receiving low or high protein diets.

The Leafhoppers Of South Dakota And Additional Distribution Records From 18 States And Canada, Burruss Mcdaniel
Agricultural Experiment Station Technical Bulletins (1939-2011)
The leafhoppers or Cicadelloidea constitute one of the largest superfamilies within the Class Insecta. All of the members of this superfamily are plant feeders. Many cause damage to fruits, cereals, forage crops, forest and shade trees, grasses and various ornamental plants. They are recorded as attacking people when occurring in large numbers on lawns, golf fairways, or other predominantly grass covered areas. They are important in the transmission of plant viruses and can reduce crop yield in small garden plots.
