Ecological Effects Of Lead Mining On Ozark Streams: In-Situ Toxicity To Woodland Crayfish (Orconectes Hylas), Ann L. Allert, James F. Fairchild, Robert J. Distefano, C.J. Schmitt, William G. Brumbaugh, J.M. Besser

United States Geological Survey: Staff Publications

The Viburnum Trend mining district in southeast Missouri, USA is one of the largest producers of lead-zinc ore in the world. Previous stream surveys found evidence of increased metal exposure and reduced population densities of crayfish immediately downstream of mining sites. We conducted an in-situ 28-d exposure to assess toxicity of mining-derived metals to the woodland crayfish (Orconectes hylas). Crayfish survival and biomass were significantly lower at mining sites than at reference and downstream sites. Metal concentrations in water, detritus, macroinvertebrates, fish, and crayfish were significantly higher at mining sites, and were negatively correlated with caged crayfish survival. …

Ground And Surface Temperature Variability For Remote Sensing Of Soil Moisture In A Heterogeneous Landscape, Mario A. Giraldo, David Bosch, Marguerite Madden, Lynn Usery, Michael Finn

United States Geological Survey: Staff Publications

At the Little River Watershed (LRW) heterogeneous landscape near Tifton Georgia US an in situ network of stations operated by the US Department of Agriculture–Agriculture Research Service-Southeast Watershed Research Lab (USDA–ARS-SEWRL) was established in 2003 for the long term study of climatic and soil biophysical processes. To develop an accurate interpolation of the in situ readings that can be used to produce distributed representations of soil moisture (SM) and energy balances at the landscape scale for remote sensing studies, we studied (1) the temporal and spatial variations of ground temperature (GT) and infra-red temperature (IRT) within 30 by 30 m …

Mice Deficient In The Serine/Threonine Protein Kinase Vrk1 Are Infertile Due To A Progressive Loss Of Spermatogonia, Matthew S. Wiebe, R. Jeremy Nichols, Tyler P. Molitor, Jill K. Lindgren, Paula Traktman

Nebraska Center for Virology: Faculty Publications

The VRK1 protein kinase has been implicated as a proproliferative factor. Genetic analyses of mutant alleles of the Drosophila and Caenorhabditis elegans VRK1 homologs have revealed phenotypes ranging from embryonic lethality to mitotic and meiotic defects with resultant sterility. Herein, we describe the first genetic analysis of murine VRK1. Two lines of mice containing distinct gene-trap integrations into the Vrk1 locus were established. Insertion into intron 12 (GT12) spared VRK1 function, enabling the examination of VRK1 expression in situ. Insertion into intron 3 (GT3) disrupted VRK1 function, but incomplete splicing to the gene trap rendered this allele hypomorphic (~15% of …

Detection, Occurrence, And Fate Of Emerging Contaminants In Agricultural Environments (2009), Daniel D. Snow, Shannon L. Bartelt-Hunt, Shannon Devivo, Samuel Saunders, David A. Cassada

Nebraska Water Center: Faculty Publications

Frequently studied environmental contaminants in agricultural systems include nutrients, sediments, and pesticides. These groups of contaminants typically occur at easily measured concentrations in surface run-off in agricultural watersheds. Nutrients, especially nitrogen, and pesticides have also been shown to impact ground water quality in areas susceptible to contamination. Less well-known are environmental impacts of newer classes of contaminants such as pharmaceuticals, steroids, antibiotic-resistance genes and prion proteins. These “emerging” contaminants clearly have potential to enter the environment and cause known or suspected adverse ecological or human health effects. Release of these contaminants to the environment often has occurred for quite some …

Selection For Immune Responses To Porcine Circovirus (Pcvz) To Decrease Incidence Of Porcine Circovirus Associated Disease (Pcvad), Jared S. Bates, Roman Moreno, Alan R. Doster, Rodger K. Johnson

Nebraska Swine Reports

Genetic and environmental effects on incidence of Porcine Circovirus Associated Disease (PCVAD) and immune responses to Porcine Circovirus 2 (PCVZ), and their relationships with body weights were studied in 3,440 pigs of the Nebraska litter size selection lines. Pigs were weighed at birth, weaning, 65, and 180 days of age and scored for symptoms of PCVAD every 10 days from 70 to 180 days of age. Necropsies were performed to confirm accuracy of scoring. PCV2 viremia, and antibodies to PCV2, Porcine Reproductive and Respiratory Syndrome Virus, Mycoplasma hyopneumoniae and Actinobacilluspleuropneumoniae were measured in serum from blood samples drawn at various …

Effect Of Corn Dried Distillers Grains With Solubles (Ddgs) On Growth Performance And Carcass Characteristics Of Growing-Finishing Gilts With Previous Exposure To Ddgs In The Nursery, Thomas E. Burkey, Phillip S. Miller, Roman Moreno, Erin E. Carney

Nebraska Swine Reports

The objective of this experiment was to evaluate the effects of high concentrations of distillers dried grains with solubles (DDGS; 30%) on growth performance and carcass characteristics of gilts, during growing-finishing, that were previously fed high concentrations of DDGS during the nursery phase. Overall (week I to 16), the following observations are noteworthy: 1) among pigs that were fed DDGS in the nursery, average daily gain (ADG) and final body weight (BW) tended (P < 0.10) to be lower during growing-finishing compared to pigs that did not receive DDGS in the nursery; 2) among pigs that received DDGS during growing-finishing, ADG tended (P < 0.10) to be lower compared to pigs that did not receive DDGS during growing-finishing; and 3) among pigs that received DDGS in both the nursery and during growing-finishing, ADG and final BW was decreased (P < 0.04) compared to pigs with no prior exposure to DDGS. With respect to carcass characteristics, loth-rib back fat was greater (P < 0.05) at the end of finisher 2 among pigs that did not receive DDGS in the nursery and hot carcass weight tended (P < 0.07) to be decreased among pigs that received DDGS in both the nursery and during growing finishing. This research indicates that the inclusion of high concentrations of DDGS in both the nursery and growing finishing periods may result in negative effects on growth performance and carcass characteristics

Effect Of Dam Parity On Growth Performance And Immunity Of Weaned Pigs, Erin E. Carney, Huyen Tran, Justin W. Bundy, Roman Moreno, Phillip S. Miller, Thomas E. Burkey

Nebraska Swine Reports

The growth performance of weaned pigs derived from different parities has not been previously evaluated; however, unpublished and anecdotal observations suggest that progeny derived from first parity (PI) dams have reduced health status and growth performance compared to progeny derived from mature sows (2 P2). The objective of the current study was to evaluate the effect of dam parity on growth performance and immune response of PI and P4 progeny during the nursery phase o fproduction. Results from this experiment suggest that P4 progeny have increased body weight and growth performance during the nursery phase of production compared to PI …

Effect Of Dam Parity On Litter Performance And Passive Immunity, Erin E. Carney, Huyen Tran, Justin W. Bundy, Roman Moreno, Matthew W. Anderson, Jeffrey M. Perkins, Phillip S. Miller, Thomas E. Burkey

Nebraska Swine Reports

Preliminary experiments (reported in the 2008 Nebraska Swine Report) suggest that progeny health status may be affected by dam parity. However, the preliminary experiments only included a small population of sows and their progeny Therefore, the objective of the current experiment was to evaluate litter performance and the production and passive transfer of immunoglobulins (Ig) in dams (PI vs. P4) and their progeny. Litter birth weight tended (P < 0.10) to be greater for P4 progeny compared to P1 progeny. No effects of dam parity were observed on circulating Ig in dams during gestation or at parturition. However, concentrations of IgA tended (P <0.09) to be greater for P4 sows compared to P1 gilts in samples of colostrum and milk and serum IgG concentrations were greater (P < 0.02) for P4 progeny compared to P1 progeny across all preweaning samples. These results suggest that litter performance and health status may be affected by dam parity.

Nutrition During Gilt Development And Genetic Line Affect Reproductive Rate Through Parity 1, Rodger K. Johnson, Phillip S. Miller, Roman Moreno, Matthew W. Anderson, Jeffrey M. Perkins, Kelsey Rhynalds, Trevor J. Glidden, Donald R. Mcclure, Thomas E. Mcgargill

Nebraska Swine Reports

Effects of allowing gilts ad libitum access to feed until breeding age or developing them with 25% energy restriction from 123 days of age to breeding on reproductive success through parity I were studied with a total of 639 gilts of two lines that differ in lean growth and reproduction. Gilts of the two lines had common sires, an industry maternal line, but dams were from different populations. One line of gilts, LW x LR, represented standard industry Large White x Landrace cross females. The other gilts, L45X, were daughters of Nebraska selection Line 45 that has been selected 27generations …

Effects Of Distillers Dried Grains With Solubles (Ddgs) And Paylean" Supplementation On Growth Performance Of Growing-Finishing Pigs, Roman Moreno, Phillip S. Miller, Thomas E. Burkey, Matthew Anderson, Jeffrey Perkins, Donald R. Mcclure, Thomas Mcgargill

Nebraska Swine Reports

Forty pigs were used in a 14-week, +phase regime study conducted to evaluate the feeding value of diets with varying concentrations of DDGS for growing-finishing pig formulated on a standardized ileal digestibility (SID) lysine (lys) basis, DDGS withdrawal at the last feeding phase, and ractopamine (RAC) supplementation four weeks prior harvesting. Treatments consisted in 0, 15 or 40% dietary DDGS inclusion supplemented or not with RAC (4.5 ppm) four weeks prior harvesting. Increased dietary DDGS inclusion resulted in a linear reduction in average daily gain (ADG) during the Grower 1 period (P = 0.002). There were no treatment effects (P …

Nebraska Swine Reports

Two-hundred and forty pigs (61.73 lb) were used in a 16-week study conducted to evaluate the feeding value of diets with varying concentrations of distillers dried grains with solubles (DDGS) for growing-finishing pigs. Pigs were assigned to one of four dietary treatments. Treatments consisted of a standard diet formulated on a standardized ileal digestible lysine (SID lys) basis in which a portion of dietary corn and soybean meal were replaced to include 0,5, 10 or 15% of DDGS in a 4-phase feeding regime. Treatment did not affect average daily gain (ADG), average daily feed intake (ADFI) or gain/feed (G:F) during …

Economy Of Adding Fibrous Feedstuffs To Sow Gestation Diets, Duane E. Reese, Allen Prosch

Nebraska Swine Reports

A previous summary of research results indicated that sows fed high-fiber diets during gestation weaned 0.3 more pigs/litter on the average than sows fed lower-fiber, grain-based diets. Gestation diets containing 18% soybean hulls, 46% distillers dried grains with solubles (DDGS), 34% wheat midds, 25% wheat bran, 23% alfalfa meal, 25% sugar beet pulp, or 45% oats provide sows about 350 g/day of neutral detergent fiber (NDF), which may be sufficient to increase litter size weaned by 0.3 pigs per litter. An economic analysis suggests that feeding a diet containing these sources of NDF would increase sow feed ingredient costs from …

Explanation Of Statistics Used In This Report

Nebraska Swine Reports

Pigs treated alike vary in performance due to their different genetic makeup and to environmental effect we cannot completely control. When a group of pigs is randomly allotted to treatments it is nearly impossible to get an "equal" group of pigs on each treatment. The natural variability among pigs and the number of pigs per treatment determine the expected variation among treatment groups due to random sampling.

At the end of an experiment, the experimenter must decide whether observed treatment differences are due to "real" effects of the treatments or to random differences due to the sample of pigs assigned …

In Vivo And In Vitro Expression Of Porcine Zinc Transporter (Znt) 1 Mrna, Huyen Tran, Phillip Miller, Thomas E. Burkey

Nebraska Swine Reports

Preliminary experiments were carried out to evaluate in vivo expression of zinc transporter (ZnT) 1 mRNA in a panel of tissues obtained from weaned pigs and to evaluate in vitro changes in ZnT1 mRNA in a porcine jejunal epithelial cell line (IPEC-J2) treated with low (40 μM) or high (80 μM) concentrations of zinc sulphate (ZnSO₄) or, in a separate experiment, with low (50 μg/ml) or high (100 μg/mL) concentrations of antibiotics (as gentamicin; GENT). Lipopolysaccharide (LPS; 10 ng/mL) was included as a negative control in both experiments. Zinc transporter 1 mRNA was detected in all tissues evaluated …

Using Material Flow Analysis For Sustainable Materials Management: Part Of The Equation For Priority Setting, Frederick W. Allen, Priscilla A. Halloran, Angela H. Leith, M. Clare Lindsay

United States Environmental Protection Agency: Publications

Many possible applications exist for material flow analysis (MFA). One of them is to help with sustainable materials management (SMM), a familiar concept to the readers of this journal— “an approach to serving human needs by using/ reusing resources most productively and sustainably throughout their life cycles, generally minimizing the amount of materials involved and all the associated environmental impacts” (EPA 2009).

Governments and industries around the world are stepping up their efforts to manage materials sustainably. But where should governments start? How should they set priorities on what materials to address? A few hundred basic materials are transformed into …

No Way Out? The Question Of Unilateral Withdrawals Of Referrals To The Icc And Other Human Rights Courts, Michael P. Scharf, Patrick Dowd

Faculty Publications

Growing out of the authors' work for the International Criminal Court, which was sponsored by a grant from the Open Society Institute, No Way Out examines one of the most vexing legal questions facing the International Criminal Court - whether a State that has referred a case to the Court can subsequently withdraw its referral as part of a domestic peace agreement? The issue has arisen with respect to Uganda's interest in withdrawing its self-referral as part of a peace deal with the leaders of the Lord's Resistance Army. This article examines the Rome Statute, the drafting history, and the …
