The Changing Face Of The Swine Industry In South Dakota: Reasons For Exit From The Industry, N. Klein, C. Tongkasame

South Dakota Swine Research Report, 2001

All livestock producers' experience cycles of high and low prices. The objective of this study was to determine what, besides the obvious reason of low prices, has caused South Dakota producers to leave the swine industry. Along with this, we hoped to identify the characteristics of producers who have exited for various different reasons, arid then to identify which attributes would have the greatest impact on a producer's decision to re-entry the swine industry. If we can identify characteristics of producers who have left for different reasons, we may be better able to form policies and educational programs to help …

Update On South Dakota's Hog Market, M.A. Diersen, J. Walti

South Dakota Swine Research Report, 2001

South Dakota farmers continue to produce a sizeable number of hogs despite recent contraction throughout the hog industry. USDA-NASS reports an inventory of over 1 million hogs in the state (SDASS). South Dakota ranked 11th among U.S. states in hog inventory and ranked 12th in pig crop size in 2000. Production practices vary from farrow-to-finish to specialization in farrowing, growing, and finishing. This paper seeks to highlight recent trends and new information related to South Dakota's hog market. Several findings pertain to national (and global) structural changes that have implications for South Dakota. With the general trend toward continuous production …

Physiological And Behavioral Variation In Estivation Among Mud Turtles (Kinosternon Spp.), Day B. Ligon, Charles C. Peterson

College of Natural and Applied Sciences

Kinosternid mud turtles, a primarily aquatic group, exhibit variable degrees of terrestrial activity in the Sonoran and Chihuahuan Deserts. We compared behavioral and physiological responses to dry conditions in four populations representing three species, Kinosternon sonoriense, Kinosternon flavescens, and Kinosternon hirtipes. All four groups were subjected to simulated dry season conditions in the laboratory, during which activity was monitored and physiological responses (blood chemistry and rates of resting metabolism and evaporative water loss) were measured. Kinosternon flavescens and K. hirtipes represented extremes in apparent ability to estivate, based on activity and rate of increase of plasma osmolality. Two populations of …

Casting New Light On An Old Subject: Death Penalty Abolitionism For A New Millennium (Reviewing Austin Sarat, When The State Kills: Capital Punishment And The American Condition (2001))., Wayne A. Logan

Scholarly Publications

This paper examines recent U.S. efforts to abolish capital punishment, using Austin Sarat's 2001 book "When the State Kills" as the centerpiece of its exploration. The book, rather than mounting a principled "frontal assault" on the death penalty, instead surveys the numerous ways in which capital punishment negatively affects American law, politics, and culture. The paper considers the broader historic significance of this tactical shift and reflects upon the consequences and prospects for its ultimate success.

Exact Level And Power Of Permutation, Bootstrap, And Asymptotic Tests Of Trend, Christopher D. Corcoran, Cyrus R. Mehta

Journal of Modern Applied Statistical Methods

We develop computational tools that can evaluate the exact size and power of three tests of trend (e.g., permutation, bootstrap and asymptotic) without resorting to large-sample theory or simulations. We then use these tools to compare the operating characteristics of the three tests. It is seen that the bootstrap test is ultra-conservative relative to the other two tests and as a result suffers from a severe deterioration in power. The power of the asymptotic test is uniformly larger than that of the other two tests, but it fails to preserve the Type I error for most of the range of …

Innovative Stormwater Treatment Technologies: Best Management Practices Manual, Jillian E. Jones, G. Dana Bisbee, Harry T. Stewart

PREP Reports & Publications

Urban stormwater carries a number of pathogens, nutrients, heavy metals, sediment, and other contaminants as surface runoff flows over land. The increase in impervious or paved surfaces associated with development in urban areas reduces the natural infiltration of precipitation into the ground. With impervious cover, precipitation collects and carries contaminants before draining into nearby surface waters. Stormwater runoff from paved surfaces in developed areas can degrade downstream waters with both contaminants and increased volumes of water. This publication aims to make information on innovative stormwater treatment technologies more available to New Hampshire’s urban planners, developers, and communities. Traditional runoff management …

Field Application Of A Monoclonal Antibody Panel To Differentiate Porcine Reproductive And Respiratory Syndrome Virus (Prrsv) Isolates, E.A. Nelson, H.A. Jones, L. Yang, K.B. Platt

South Dakota Swine Research Report, 2001

Porcine reproductive and respiratory syndrome (PRRS) is recognized as the most economically devastating disease of swine throughout the world. Nucleotide sequencing and serological studies have deomnstrated sustantial antigenic variation amoung PRRS virus (PRRSV) isolates (Murtaugh, et al., 1995; Nelson, et al., 1993, 1996). Recently, European-like PRRSV isolates have been identified in the US (Rossow, et al. 2000) and other new, highly virulent PRRSV isolates have appeared and affect sows at all stages of gestation causing mortality of adult pigs as well as young pigs (Epperson et al., 1997). Therefore, it is even more important to control the spread of these …

Efficacy Of High Oil Corn In Reducing The Severity Of A Prrsv Challenge In Growing Pigs, B.T. Christopherson, R.C. Thaler, C.C. Chase, S.H. Pohl

South Dakota Swine Research Report, 2001

The objectives of this experiment were to determine the effects of high oil corn (HOC) on the aerosol transmission of the porcine reproductive and respiratory synrome virus (PRRSV), and the effects of HOC on PRRSV seroconversion in growing pigs. One hundred PRRSV negative gilts (25 kg) were housed in 1 of 2 mirror imaged rooms. Both rooms contained 10 pens with 5 pigs/pen, and each room had its own separate ventilation and maure handling systems. The study was arranged in a 2 x 2 factorial arrangement. The main effects consisted of a dietary energy source, (#2 yellow corn (CON) and …

The Future Of Using Antibiotics In Livestock Feeding, H.H. Stein Ph.D.

South Dakota Swine Research Report, 2001

For more than 50 years, it has been recognized that livestock performance can be improved if antibiotics are included in the diets at sub-therapeutic levels. As a result, a relatively large number of feed antibiotics have been approved for livestock feeding, and it is common praxis all over the world to include one or more antibiotics in the diets for production animals. Typically, daily gain and feed utilization are improved by 5 to 10% by the inclusion of these antibiotic growth promoters.

Effects Of Administration Of Estradiol-17p On The Serum And Anterior Pituitary Igf System In Pigs, L.A. Rempel, J.A. Clapper

South Dakota Swine Research Report, 2001

The anterior pituitary (AP) gland functions as a storage and releasing unit for several hormones; growth hormone (GH), gonadotrophins (luteinizing hormone and follicle stimulating hormone), prolactin, adrenocorticotropin hormone, and tyroid stimulating hormone. Luteinizing hormone (LH) functions to increase ovarian follicular growth and maturation and responds to increasing concentrations of estradiol-17β (E2) that occur at estrus to cause ovulation. Production and secretion of the protein, insulin-like grwoth factor-I (IGF-I), occurs primarily in the liver, in response to GH release from the anterior pituitary gland. Insulin-like growth factor-I increases glucose uptake, amino acid transport, and glycogen synthesis resulting in increased protein accretion …

Lean Growth And Overall Performance Of Pigs During The Finisher Phase As Affected By Lean Growth Potential Determined During The Grower Phase And Dietary Protein Level During The Finisher Phase, J.N. Tembei, G.W. Libal, D.N. Peters

South Dakota Swine Research Report, 2001

Selection for decreased backfat thickness and faster rate of gain has resulted in pigs with increased potential for lean gain. Although energy intake is the limiting factor for lean growth during the grower period, the underlying limiting factor to support increased protein accretion during the finishing stage seems to be lysine intake. At the finishing phase, pigs consume enough feed per day to meet their energy requirements, but protein is the most limiting nutrient Genetics and sex influence growth performance and protein accretion in finishing pigs. Pigs from different protein requirements and these differences have been associated with differences in …

Environmental Effects On Growing Swine Performance, S.H. Pohl, R.C. Thaler, B.D. Rops, J.A. Nienaber

South Dakota Swine Research Report, 2001

The effects of environmental conditions on performance of growing pigs (30-50 kg) were studied over a four-week period. Pigs were exposed to natural occurring diurnal temperatures and a constant 32°C ambient temperature during normally hot weather conditions and constant 21 and 10°C ambient temperature conditions during cold weather. For each temperature treatment pigs were divided into single, 9 and 18 head per pen groups. The constant 32°C ambient temperature had a significant (P<0.05) effect on average daily gain and feed intake. Average daily gains were reduced from 0.72 to 0.64 kg/d and average daily feed intake was reduced from 1.53kg/d to 1.36 kg/d when comparing pig performance from the naturally occurring diurnal to constant 32°C temperature treatments. The 10°C cold weather treatment had no significant {P>0.05) effects on overall pig performance. Pigs from the 10°C treatment gained at a rate of 0. 72 vs 0.74 kg/d for pigs in the 21°C treatment. …

Analysis Of Protein Sequences Using Time Frequency And Kolmogorov-Smirnov Methods, Kobby Essien

Dartmouth College Undergraduate Theses

The plethora of genomic data currently available has resulted in a search for new algorithms and analysis techniques to interpret genomic data. In this two-fold study we explore techniques for locating critical amino acid residues in protein sequences and for estimating the similarity between proteins. We demonstrate the use of the Short-Time Fourier Transform and the Continuous Wavelet Transform together with amino acid hydrophobicity in locating important amino acid domains in proteins and also show that the Kolmogorov-Smirnov statistic can be used as a metric of protein similarity.

Effect Of Body Fat Measurement At Breeding And Gestation Energy Level On Farrowing And Lactation Performance Of First Parity Sows, G.W. Libal

South Dakota Swine Research Report, 2001

Records kept by the swine industry reveal that a large precentage of females entering the sow herd are culled prior to reaching their peak reproductive performance expected in their fourth to sixth parity. In herds with low replacement rates over 30% of the females are culled and in herds with high replacement rates this figure exceeds 50% annually. Of those sows not culled for health or structural problems, most are removed because they fail to return to estrus or fail to maintain pregnancy after their first or second litter. Low feed intake and excessive weight loss during lactation have been …

Transmission Of Porcine Reproductive And Respiratory Syndrome Virus By Semen Is Dose Dependent, C.D. Nelson, R.R. Rowland, D.A. Benfield

South Dakota Swine Research Report, 2001

Procine reproductive and respiratory syndrome virus (PRRSV) is transmitted through semen via natural mating or atrificial insemination. However, the minimal infective dose of PRRSV required to effect transmission through semen is not known. In this study, we induced estrus in PRRSV seronegative gilts and then artificially inseminated these animals with extended, commercial boar semen “seeded” with difference concentrations (2, 20, 200, 2,000, 20,000, 200,000, or 2,000,000 TCID50/50 ml of semen) of the PRRSV isolate SD 92-23983. Infection of gilts by PRRSV was confirmed by weekly bleedings of these animals to detect serconversion using the commercial IDEXX ELISA. All pigs (n=7) …

South Dakota's Hog Market: Developments And Prospects, M.A. Diersen

South Dakota Swine Research Report, 2001

Raising hogs and pigs tends to be South Dakota's second largest livestock enterprise based on sales revenue of about $200 million in 1999. Although it lags substantially behind raising beef cattle, hog production continues to contribute to South Dakota's economic base. South Dakota ranked 11th among U.S. states in hog inventory and ranked 12th in pig crop size in 1999. Production practices vary from farrow-to finish to specialization in farrowing, growing, and finishing. Based on inventory numbers, hogs consume a substantial portion of the corn and soybean meal produced in South Dakota. The year 2000 should bring about the first …

Matched Terminal Deletions, Rex Gooch

Word Ways

In Kickshaws of Feb 2002, Dave Morice asked for words beginning and ending in the same letter, which revealed other words (say, core words) when the terminal letters were discarded. He asked for the longest source words beginning with each letter of the alphabet, in each of four categories: the revealed word reads forwards; reads backwards; reads a different word forwards from backwards (called "both" below, his example was STARS - TAR + RAT); and reads the same backwards and forwards (palindrome).
