Reducing Phosphorus Concentration of Ethanol Distiller Byproducts by Using Low Grain Phosphorus Corn

Ethanol production plants are using about 800 million bu of corn each year to produce ethanol. In the ethanol production system, the starch is converted to ethanol and CO2 and the remaining grain material is called distiller byproduct (wet distiller grain plus soluble or dry distiller grain plus soluble). This byproduct is high in energy, protein, and P contents and is usually fed to feedlot cattle and other livestock. Removal of starch from grain concentrates P in the byproduct and when this high P material is added …

Rural Development Through Pork Production: The Nebraska Model

Nebraska’s producers of pork are striving to create systems of production that are environmentally, economically & socially acceptable.
This is no small challenge. While attempting to comply with environmental rules, producers are faced with the rules changing as they implement adoption. Social acceptance varies with locale but is generally less positive than in the past. And, Fewer operations have livestock and fewer people in the rural population rely on livestock for their livelihoods—which makes any livestock production operation less acceptable.
The issues facing all agricultural producers today are more complex and difficult …

New BSE Rule Will Change Re-Feeding of Poultry Litter to Ruminants

The Food and Drug Administration announced on January 26, 2004 several new public health measures, to be implemented, to strengthen significantly the multiple existing firewalls that protect Americans from exposure to the agent thought to cause bovine spongiform encephalopathy (BSE, also known as mad cow disease) and that help prevent the spread of BSE in U.S. cattle. One of those changes will impact how re-feeding of waste to animals is allowed.
To implement these new protections, FDA will publish two interim final rules that will take effect immediately upon …

Alternative Treatment Systems

The February 13, 2003 Federal Register revised the Environmental Protection Agency’s (EPA’s) “Part 412-Concentrated Animal Feeding Operations (CAFO) Point Source Category,” which described the revised Effluent Limitations Guidelines (ELG) and New Source Performance Standards (NSPS) for concentrated animal feeding operations (CAFOs). The regulation applies to manure, litter, and/or process wastewater discharges resulting from CAFOs. Subpart C addresses dairy cows and cattle other than veal calves, which includes dairy operations and beef cattle feedlots. Subpart D addresses swine, poultry, and veal calves. Baseline ELGs in the revised rule prohibit discharge of process waste waters except when rainfall events …

A Brief History and Background of the EPA CAFO Rule

U.S. Environmental Protection Agency (EPA) rules affecting animal feeding operations (AFOs) have evolved from the 1972 Federal Clean Water Act (CWA). Section 502 of the CWA specifically defined “feedlots” as “point sources” along with dozens of other industries such as meat processing and fertilizer manufacturing. The goal of the 1972 CWA was to restore “fishable, swimmable” quality of lakes, streams, and estuaries in the United States.
A federal permit program termed the National Pollutant Discharge Elimination System (NPDES) was created for point sources that discharged into “waters of the United …

Wheatbelt Waterwise = Saltwise : Gardening Guide, John Colwill, Juana Roe

Bulletins 4000 -

As a result of agricultural clearing, many country towns are now feeling the effects of rising groundwater and the salt that it carries. Salinity has been identified as Australia’s number one environmental problem. While most people think that salinity means land lost to agriculture, it also poses a serious threat to many country towns. A report for the Department of Agriculture in 2001 highlighted the need for simple and cost-effective salinity management strategies to be adopted in wheatbelt towns. These included water recycling, revegetation and more efficient water use.

Escherichia Coli O157:H7 In The Gallbladders Of Experimentally Infected Calves, William C. Stoffregen, Joachim F. L. Pohlenz, Evelyn A. Dean-Nystrom

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Fifteen weaned calves (age 89–141 days) were treated with dexamethasone (0.25 mg/kg, IV) for 3 days before, the day of, and the day after inoculation with 10 colony-forming units of either Escherichia coli O157:H7 (strain 86-24, which produces Shiga toxin 2 and intimin; n=13) or nonpathogenic E. coli (strain 123, which does not produce Shiga toxin or intimin; n=2). All calves were necropsied 4 days after inoculation. Histologic lesions of attaching and effacing bacteria were observed in the large intestine (12/13) and in the gallbladder mucosa (5/13) of calves inoculated with E. coli 86-24. Cholecystitis was present in 12 of …

Detection And Characterization Of Amitraz Resistance In The Southern Cattle Tick, Boophilus Microplus (Acari: Ixodidae), Andrew Y. Li, Ronald B. Davey, Robert J. Miller, John E. George

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Amitraz, a formamidine acaricide, plays an important role in the control of the southern cattle tick, Boophilus microplus (Canestrini), and other tick species that infest cattle, dogs, and wild animals. Although resistance to amitraz in B. microplus was previously reported in several countries, the actual measurement of the level of amitraz resistance in ticks has been difficult to determine due to the lack of a proper bioassay technique. We conducted a survey, by using a newly reported technique that was a modification of the standard Food and Agriculture Organization larval packet test, to measure the levels of resistance to amitraz …

Crop Performance And Soil Properties Of Sites Previously Used For Production Of Beef Cattle Manure Compost, Daniel Ginting, Bahman Eghball, Daniel T. Walters, Charles A. Francis, Terry J. Klopfenstein, Casey Wilson, Galen E. Erickson

Nebraska Beef Cattle Reports

This study was established on sites that had three or seven years of compost production history. Corn, wheat, barley, sorghum and alfalfa were planted in 2001. In the first year, wheat, barley and sorghum performed better than corn in the windrow areas while alfalfa did not even establish because of excessive salt in the soil. Soil electrical conductivity, K and Na in the 0-6 inch depth under windrows were high and caused soil crusting and poor germination and crop yields. Growing salt tolerant crops, such as barley, can rehabilitate sites used for composting and the process can be accelerated by …

Department of Agronomy and Horticulture: Faculty Publications

Soybean [Glycine max (L.) Merr.] is a versatile crop due to its multitude of uses as a high protein meal and vegetable oil. Soybean seed traits such as seed protein and oil concentration and seed size are important quantitative traits. The objective of this study was to identify representative protein, oil, and seed size quantitative trait loci (QTL) in soybean. A recombinant inbred line (RIL) population consisting of 131 F6-derived lines was created from two prominent ancestors of North American soy-beans (‘Essex’ and ‘Williams’) and the RILs were grown in six environments. One hundred simple sequence repeat (SSR) markers …

Glycosyltransferases Encoded By Viruses, Nicolas Markine-Goriaynoff, Laurent Gillet, James L. Van Etten, Haralambos Korres, Naresh Verma, Alain Vanderplasschen

James Van Etten Publications

Studies of cellular biology in recent decades have highlighted the crucial roles of glycans in numerous important biological processes, raising the concept of glycomics that is now considered as important as genomics, transcriptomics and proteomics. For millions of years, viruses have been co-evolving with their hosts. Consequently, during this co-evolution process, viruses have acquired mechanisms to mimic, hijack or sabotage host processes that favour their replication, including mechanisms to modify the glycome. The importance of the glycome in the regulation of host–virus interactions has recently led to a new concept called ‘glycovirology’. One fascinating aspect of glycovirology is the study …

The Hopptof Locus Of Pseudomonas Syringae Pv. Tomato Dc3000 Encodes A Type Iii Chaperone And A Cognate Effector, Libo Shan, Hye-Sook Oh, Jianfu Chen, Ming Guo, Jianmin Zhou, James R. Alfano, Alan Collmer, Xu Jia, Xiaoyan Tang

Department of Plant Pathology: Faculty Publications

Type III secretion systems are highly conserved among gram-negative plant and animal pathogenic bacteria. Through the type III secretion system, bacteria inject a number of virulence proteins into the host cells. Analysis of the whole genome sequence of Pseudomonas syringae pv. tomato DC3000 strain identified a locus, named HopPtoF, that is homologous to the avirulence gene locus avrPphF in P. syringae pv. phaseolicola. The HopPtoF locus harbors two genes, ShcF_Pto and HopF_Pto, that are preceded by a single hrp box promoter. We present evidence here to show that ShcF_Pto and HopF_Pto encode a type …

Nematode Molecular Diagnostics: From Bands To Barcodes, Tom Powers

Department of Plant Pathology: Faculty Publications

Nematodes are considered among the most difficult animals to identify. DNA-based diagnostic methods have already gained acceptance in applications ranging from quarantine determinations to assessments of biodiversity. Researchers are currently in an information-gathering mode, with intensive efforts applied to accumulating nucleotide sequence of 18S and 28S ribosomal genes, internally transcribed spacer regions, and mitochondrial genes. Important linkages with collateral data such as digitized images, video clips and specimen voucher web pages are being established on GenBank and NemATOL, the nematode-specific Tree of Life database. The growing DNA taxonomy of nematodes has lead to their use in testing specific short sequences …

Type Iii Secretion System Effector Proteins: Double Agents In Bacterial Disease And Plant Defense, James R. Alfano, Alan Collmer

Department of Plant Pathology: Faculty Publications

Many phytopathogenic bacteria inject virulence effector proteins into plant cells via a Hrp type III secretion system (TTSS). Without the TTSS, these pathogens cannot defeat basal defenses, grow in plants, produce disease lesions in hosts, or elicit the hypersensitive response (HR) in nonhosts. Pathogen genome projects employing bioinformatic methods to identify TTSS Hrp regulon promoters and TTSS pathway targeting signals suggest that phytopathogenic Pseudomonas, Xanthomonas, and Ralstonia spp. harbor large arsenals of effectors. The Hrp TTSS employs cus- tomized cytoplasmic chaperones, conserved export components in the bacterial en- velope (also used by the TTSS of animal pathogens), and …

Chemical Defenses In Garlic Mustard (Alliaria Petiolata) And Their Potential Role In Species Interactions In Forest Understories, Don Cipollini

Biological Sciences Faculty Publications

Garlic mustard [Alliaria petiolata [(M. Bieb) Cavara & Grande; Brassicaceae] is a European native biennial herb, first recorded on Long Island, NY in the 1860s, and is expanding rapidly in northeastern and midwestern forests in the U.S. and in southern Canada. Garlic mustard flourishes in moist woodlands with moderate exposure to light, but it can grow in a diversity of other habitats. It is found in natural areas, woodlots, and along edges of agricultural fields and lawns throughout North America. Several life history traits likely contribute to the invasiveness of this species. It has a high inbreeding rate and can …

Boll Weevil (Anthonomus Grandis Boheman) (Coleoptera: Curculionidae) Dispersal In The Southern United States: Evidence From Mitochondrial Dna Variation, Kyung Seok Kim, Thomas W. Sappington

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

An understanding of boll weevil (Anthonomus grandis Boheman) dispersal behavior is essential to characterizing and responding to the threat of migration into eradication zones. Genetic variation in boll weevil mitochondrial DNA (mtDNA) was sampled and analyzed to make inferences on the magnitude and geographic pattern of genetic differentiation among weevil populations from 20 locations across eight U.S. states and northeast Mexico. Polymerase chain reaction (PCR)-restriction fragment length polymorphisms (RFLPs) analysis was conducted on a 12.4-kb amplicon of mtDNA from each of 419 individuals.A total of 28 distinct mtDNA haplotypes, 17 of which were unique to single locations, were identified …

Windbreaks In North American Agricultural Systems, James R. Brandle, Laurie Hodges, Xinhua H. Zhou

Department of Agronomy and Horticulture: Faculty Publications

Windbreaks are a major component of successful agricultural systems throughout the world. The focus of this chapter is on temperate-zone, commercial, agricultural systems in North America, where windbreaks contribute to both producer profitability and environmental quality by increasing crop production while simultaneously reducing the level of off-farm inputs. They help control erosion and blowing snow, improve animal health and survival under winter conditions, reduce energy consumption of the farmstead unit, and enhance habitat diversity, providing refuges for predatory birds and insects. On a larger landscape scale windbreaks provide habitat for various types of wildlife and have the potential to contribute …

The High Mountain Vegetation Of Turkey - A State Of The Art Report, Including A First Annotated Conspectus Of The Major Syntaxa, Gerald Parolly

Turkish Journal of Botany

This contribution spotlights the present research on the (oreal) subalpine to subnival mountain vegetation of Turkey. It concisely compiles our present knowledge, which is very heterogeneous in geographical terms. The situation is comparatively good in NW and W Anatolia and the western half of the Taurus range, from where a first consolidation stage can be reported. By contrast, the E Taurus remains a largely unexplored area. The Pontic chains have hitherto attracted a few local researchers only, and those important pioneering accounts cover less than half of the vegetation types actually present. The results of the last years' field work …
