Small Mammals In Prairie Wetlands: Habitat Use And The Effects Of Wetland Modifications, Grey W. Pendleton Jan 1984

Small Mammals In Prairie Wetlands: Habitat Use And The Effects Of Wetland Modifications, Grey W. Pendleton

Electronic Theses and Dissertations

Although well documented for other habitat types, small mammal habitat use patterns in prairie wetlands are poorly understood. The distribution of the mammal fauna of South Dakota is also not well known. Because of the lack of information in these areas, evaluation of the impacts of wetland modifications on the resident mammal community is not possible. The objectives of this study were (1) to document the species composition and abundance of small mammal communities inhabiting prairie wetland basins, (2) to determine the effects of small scale habitat modification on small mammals, (3) and to explain local species distribution patterns using …

Feed Additive Additions To Pig Creep Feed, G. W. Libal, R. C. Wahlstrom Nov 1983

Feed Additive Additions To Pig Creep Feed, G. W. Libal, R. C. Wahlstrom

South Dakota Swine Field Day Proceedings and Research Reports, 1983

Considerable variation often occurs in litter performance and survivability during the lactation period. While most pig losses occur during early lactation, some deaths do occur after the pig is old enough to consume part of its dietary needs from creep feed.
The study reported herein was designed .to evaluate the effect of adding Neo-Terramycin or Aurea SP-250 to the creep diets from day 14 to day 28 of lactation.

Limiting Amino Acids In Sunflower Meal For Growing Swine, R. C. Wahlstrom, R. C. Thaler, G. W. Libal Nov 1983

Limiting Amino Acids In Sunflower Meal For Growing Swine, R. C. Wahlstrom, R. C. Thaler, G. W. Libal

South Dakota Swine Field Day Proceedings and Research Reports, 1983

Increased production of sunflower seeds, particularly in South Dakota, North Dakota and Minnesota, has increased the availability of sunflower meal as a protein supplement source for livestock diets. Previous research has shown that sunflower meal is not a good source of the amino acid lysine, the first limiting amino acid in sunflower meal. If lysine is available at a competitive cost, economical diets can be. formulated using synthetic lysine and sunflower meal that are equal in lysine content to diets using soybean meal as the protein source. This study was conducted to identify other limiting amino acids in a lysine …

The Effect Of Feeding Frequency And Feed Flavoring On Performance Of Lactating Sows And Gilts, G. W. Libal, R. C. Wahlstrom Nov 1983

The Effect Of Feeding Frequency And Feed Flavoring On Performance Of Lactating Sows And Gilts, G. W. Libal, R. C. Wahlstrom

South Dakota Swine Field Day Proceedings and Research Reports, 1983

Inadequate feed consumption by sows (below 10 lb/day) in the farrowing house accompanied by large weight losses during lactation is a major problem in the swine industry. Excessive sow weight loss is often associated with poor milking performance and delayed return to estrus after weaning. High temperature in the farrowing house is often to blame for inadequate feed intake. However, even under the most ideal management the problem often exists. The trial reported herein is a part of a regional study (NCR-89, Confinement Management of Swine) to evaluate the effect of feeding frequency and the addition of sugar to the …

Sunflower Seeds In Growing-Finishing Swine Diets, A. D. Hartman, R. C. Wahlstrom, G. W. Libal Nov 1983

Sunflower Seeds In Growing-Finishing Swine Diets, A. D. Hartman, R. C. Wahlstrom, G. W. Libal

South Dakota Swine Field Day Proceedings and Research Reports, 1983

South Dakota has become a leader in the production of sunflowers during the past few years. Sunflowers are an excellent oil. crop as they may contain 40% oil that is highly unsaturated in nature. In swine diets, the addition of sunflower seeds would replace mainly the grain or carbohydrate source in the diet, This would increase the energy content of the diet and shift the energy source from carbohydrate to a mixture of carbohydrates and fat. A previous experiment reported in the 1982 South Dakota Swine Day proceedings indicated that 20% dietary sunflower seeds reduced rate of gain and produced …

The Effect Of Selenium On Pigs Of Different Hair Color, R. C. Wahlstrom, T. B. Goehring, G. W. Libal, O. E. Olson Nov 1983

The Effect Of Selenium On Pigs Of Different Hair Color, R. C. Wahlstrom, T. B. Goehring, G. W. Libal, O. E. Olson

South Dakota Swine Field Day Proceedings and Research Reports, 1983

It has been suggested that levels of certain trace elements in hair may be associated with the dietary intake of the element. High levels of selenium in the diet have been shown to increase hair selenium in swine and also in cattle. The possibility that the degree of selenium toxicity is related to hair color has been proposed for cattle, horses and swine.
This study was conducted to determine if storage of selenium in the hair of pigs varied with their color and also to determine if hair color was related to degree of selenium toxicity.

Selenium Toxicity In Growing Swine, T. B. Goehring, O. E. Olson, I. S. Palmer, G. W. Libal Nov 1983

Selenium Toxicity In Growing Swine, T. B. Goehring, O. E. Olson, I. S. Palmer, G. W. Libal

South Dakota Swine Field Day Proceedings and Research Reports, 1983

The Food and Drug Administration has approved sodium selenite and sodium selenate as supplements to pig starter diets up to a level of .3 parts per million (ppm) of selenium. In view of this, the potential exists for selenium poisoning to occur through accidental contamination, incorrect mixing or incorrect formulation of the diet. However, little research has been conducted to determine the maximum level of dietary selenium that could be tolerated without affecting pig performance.
The objectives of this study were to establish the level at which selenium becomes toxic to growing swine and to determine which of the parameters …

Pen Space And Antibiotic Effects On Performance Of Growing-Finishing Pigs, G. W. Libal, R. C. Wahlstrom, Roland Hanson Nov 1983

Pen Space And Antibiotic Effects On Performance Of Growing-Finishing Pigs, G. W. Libal, R. C. Wahlstrom, Roland Hanson

South Dakota Swine Field Day Proceedings and Research Reports, 1983

The detrimental effects of crowding weaned pigs and the advantage of inclusion of an antibiotic in the diets fed from 4 weeks of age to 40 lb has been documented (SWINE 81-8) as a part of a North Central regional project by the Swine Confinement Management Committee. It is of interest to know if the same responses to crowding and presence of antibiotics can be observed with growing-finishing pigs. This study, also part of a regional study, was designed to evaluate the possible effect of antibiotics and pen space on growing-finishing pigs and the interaction of these two factors.

Effect Of Lysine In Starter Diets On Performance And Carcass Characteristics Of Swine, R. C. Thaler, R. C. Wahlstrom, G. W. Libal Nov 1983

Effect Of Lysine In Starter Diets On Performance And Carcass Characteristics Of Swine, R. C. Thaler, R. C. Wahlstrom, G. W. Libal

South Dakota Swine Field Day Proceedings and Research Reports, 1983

Current research indicates that the lysine level suggested by the National Research Council for starter pigs (10 to 20 kg) may be inadequate. Lysine, the first limiting amino acid in most swine rations, is mainly provided by soybean meal in cereal-based diets. With the increasing price of soybean meal, it is important to determine the correct lysine requirement in order to minimize the amount of soybean meal needed in the ration. In low protein diets, lysine has been shown to increase rate of gain and decrease feed/gain in swine.· It also effects carcass characteristics by increasing loin-eye area and total …

Effect Of Virginiamycin On Growth And Carcass Characteristics Of Barrows And Gilts, R. C. Wahlstrom, A. D. Hartman, G. W. Libal Nov 1983

Effect Of Virginiamycin On Growth And Carcass Characteristics Of Barrows And Gilts, R. C. Wahlstrom, A. D. Hartman, G. W. Libal

South Dakota Swine Field Day Proceedings and Research Reports, 1983

Antibiotics have been used as additives to swine diets for approximately 30 years. Various antibiotics have been shown to improve growth performance and efficiency of feed utilization. In addition, antibiotics have reduced low order infection. Since different organisms are sensitive to different antibiotics, the antibiotic of choice may vary depending on the organisms present. The effect of antibiotics on carcass characteristics has been less conclusive.
This experiment was conducted to determine the effect of the antibiotic, virginiamycin, on performance and carcass characteristics of barrows and gilts fed separately.

The Effects Of Sarsaponin And Bacitracin Md On Performance Of Growing-Finishing Pigs, G. W. Libal, R. C. Wahlstrom, Roland Hanson Nov 1983

The Effects Of Sarsaponin And Bacitracin Md On Performance Of Growing-Finishing Pigs, G. W. Libal, R. C. Wahlstrom, Roland Hanson

South Dakota Swine Field Day Proceedings and Research Reports, 1983

Feed additives have been used to promote growth and feed efficiency of growing-finishing pigs for over 30 years. Typically, greatest response is found during early stages of growth and less response during the finishing period under conditions of good management. Recently, sarsaponin, a naturally occurring plant steroid derived from the yucca plant, has become available as a feed additive under the commercial name, Micro-Aid. Claims for this product include increased performance of· pigs during the finishing period. The antibiotic, Bacitracin MD, also has been shown to improve performance during later stages of growth more than is expected of most feed …

Full-Fat Sunflower Seeds For Growing Pullets, Ali B. Kashani, C. Wendell Carlson Nov 1983

Full-Fat Sunflower Seeds For Growing Pullets, Ali B. Kashani, C. Wendell Carlson

South Dakota Poultry Field Day Proceedings and Research Reports, 1983

In a previous study (POULTRY 82-1), full-fat sunflower seeds (FFSS) containing 42.0% ether extract depressed pullet growth and delayed sexual maturity as indicated by egg production records for the early stages of production. The FFSS fed was at 38% of a corn-based, 12% protein diet from 10 to 19 weeks of age. The same sample of FFSS at 19% of the complete diet along with 4% soybean meal was satisfactory with respect to growth and the onset of egg production. The egg production rate during later stages appeared to be unaffected by the FFSS content of the grower diet.

Effects Of Aureomycin And Negative Ions On Egg Production, Ali B. Kashani, C. Wendell Carlson Nov 1983

Effects Of Aureomycin And Negative Ions On Egg Production, Ali B. Kashani, C. Wendell Carlson

South Dakota Poultry Field Day Proceedings and Research Reports, 1983

Egg production records from last year's experiment (see POULTRY 82-3) showed that laying hens responded to an Aureomycin addition (100 g per ton of feed fed 1 week per 28-day period) after a 2-month adaptation period. The beneficial effect of the antibiotic remained consistent during the later stages of production up to the 14th period, which resulted in an overall significant increase of 1.2% (Table 1). Other parameters measured were not significantly influenced by the addition of Aureomycin to the oats-based layer diet.

Effect Of Form Of Feed On Turkey Performance, M. Hassibi, C. W. Carlson, R. M. Luther Nov 1983

Effect Of Form Of Feed On Turkey Performance, M. Hassibi, C. W. Carlson, R. M. Luther

South Dakota Poultry Field Day Proceedings and Research Reports, 1983

Pelleting feed has been shown under some conditions to increase rate of gain and improve feed conversion in studies with poultry as it has for cattle and swine. Many investigators have reported that the principal effect of pelleting is to increase the density of the feed, thus allowing, greater intake and consequently an increase in rate of growth. Efficiency of feed utilization also is frequently improved. To investigate this further, a factorial experiment was designed to evaluate the effect of forms of feed (original mash, firm pellet and poor pellet) on turkey performance (body weight, feed/gain, etc.) when a high …

Further Studies On Fatty Liver Hemorrhagic Syndrome, Chandi C. Rakshit, C. W. Carlson Nov 1983

Further Studies On Fatty Liver Hemorrhagic Syndrome, Chandi C. Rakshit, C. W. Carlson

South Dakota Poultry Field Day Proceedings and Research Reports, 1983

Fatty liver hemorrhagic syndrome (FLHS) has been one of the major problems in the poultry industry. Although we are not sure of the cause, we can say that nutrition plays an important role in that some dietary ingredients have reduced the incidence of FLHS in previous experiments at this research center (see A.S. Series 76-1, 77-27, 78-5, 79-24, POULTRY 80-4 and 81-5).
A further experiment was conducted to ascertain the effect of different levels of fat additions as well as oats on FLHS.

Effect Of Terramycin And Copper On The Growth Of Turkeys, Hossein Samie, A. B. Kashani Nov 1983

Effect Of Terramycin And Copper On The Growth Of Turkeys, Hossein Samie, A. B. Kashani

South Dakota Poultry Field Day Proceedings and Research Reports, 1983

Studies on the use of feed additives has occupied much attention at this research center. Addition of 60 ppm copper (Cu) has been shown to improve growth rate of turkeys up to 8 weeks of age, while 120 ppm Cu depressed growth at this age, presumably due to inhibition of the utilization of sulfur amino acids. Our previous study (POULTRY 82-2) has also shown that Terramycin at 80 g per ton improved rate of gain up to 12 weeks of age. The objective of the current study was to investigate the effects of a combination of Neomycin and Terramycin (Neo-Terramycin) …

Swine Marketing In South Dakota: Results Of A Producer Survey, Larry Janssen, Kevin K. Weischedel

Economics Research Reports (1969 - 2017)

South Dakota is one of the top 10 hog production states with about 3 m111ion hogs and pigs marketed and 3.2 million hogs slaughtered in the state each year. This totals 3-4 percent of the nation's hog supply. With ample supplies of available land, labor, and feed grain there is considerable potential for further growth of the South Dakota pork industry if the expansion can be based on profitable production and marketing prospects for producers. In 1980, a pork marketing study was initiated by SDSU to obtain current infonnation on: 1) Organization of hog production and marketing in South Dakota, …
