Nebraska's Corporate-Farming Law And Discriminatory Effects Under The Dormant Commerce Clause, Anthony Schutz

Nebraska Law Review

Laws dealing with agriculture have generated a great deal of constitutional law. This Article explores one more recent example. Corporate- farming laws are one hallmark of agricultural law. They regulate the use of limited liability business forms for owning agricultural land, engaging in production agriculture, or both on approximately 312 million acres of farmland in nine states. That is approximately 77% of the land in those states and approximately one-third of all farmland in the United States. These regulations generally take the form of restricting the use of limited liability to those producers that the legislature or electorate have deemed …

Declining Global Per Capita Agricultural Production And Warming Oceans Threaten Food Security, Chris C. Funk, Molly E. Brown

United States National Aeronautics and Space Administration: Publications

Despite accelerating globalization, most people still eat food that is grown locally. Developing countries with weak purchasing power tend to import as little food as possible from global markets, suffering consumption deficits during times of high prices or production declines. Local agricultural production, therefore, is critical to both food security and economic development among the rural poor. The level of local agricultural production, in turn, will be determined by the amount and quality of arable land, the amount and quality of agricultural inputs (fertilizer, seeds, pesticides, etc.), as well as farm-related technology, practices and policies. This paper discusses several emerging …

Not All Oak Gall Wasps Gall Oaks: The Description Of Dryocosmus Rileypokei, A New, Apostate Species Of Cynipini From California, Matthew L. Buffington, Shelah I. Morita

USDA Systematic Entomology Laboratory

Cynipini gall wasps (Hymenoptera: Cynipidae) are commonly known as oak gall wasps for their almost exclusive use of oak (Quercus spp.; Fagaceae) as their host plant. Previously, only three of the nearly 1,000 species of Cynipini have been recorded from hosts other than Quercus. These three are known from western chinquapin (Chrysolepis), chestnut (Castanea) and tan bark oak (Lithocarpus), all lineages of Fagaceae related to Quercus. Here we describe Dryocosmus rileypokei Morita & Buffington, new species, a second species of cynipine which attacks Chrysolepis. Unlike the previously known gall wasp …

Perchlorate In Wet Deposition Across North America, Srinath Rajagopalan, Todd A. Anderson, Stephen Cox, Greg Harvey, Qiuqiong Cheng, W. Andrew Jackson

United States Air Force: Publications

Natural perchlorate is believed to be of atmospheric origin, yet no systematic study has been conducted to evaluate perchlorate deposition rate and possible seasonal or spatial variations. This study evaluated perchlorate concentrations in weekly composite wet deposition samples acquired through the National Atmospheric DepositionProgramfrom 26 sites across the continental United States, Alaska, and Puerto Rico for a 1-3 year period. Perchlorate concentrations varied from /L to a high of 102 ng/L with a mean of 14.1±13.5 ng/L for the 1578 total samples. The annual perchlorate flux by site ranged from a low of 12.5 (TX) to 157 mg/ha-year (NE) and …

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

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 …

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

Nebraska Swine Reports

Forty pigs were used in a 14-week, 4-phase regime study conducted to evaluate the feeding value of diets with varying concentrations of DDGS for growing-fi nishing 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.

Fungal Physiology: A Future Perspective, Richard A. Wilson, Nicholas J. Talbot

Fungal Molecular Plant-Microbe Interactions

The study of fungal physiology is set to change dramatically in the next few years as highly scalable technologies are deployed allowing accurate measurement and identification of metabolites, proteins and transcripts within cells. The advent of next-generation DNA-sequencing technologies will also provide genome sequence information from large numbers of industrially relevant and pathogenic fungal species, and allow comparative genome analysis between strains and populations of fungi. When coupled with advances in gene functional analysis, protein-protein interaction studies, live cell imaging and mathematical modelling, this promises a step-change in our understanding of how fungal cells operate as integrated dynamic living systems

Under Pressure: Investigating The Biology Of Plant Infection By Magnaporthe Oryza, Nicholas J. Talbot, Richard A. Wilson

Fungal Molecular Plant-Microbe Interactions

The filamentous fungus Magnaporthe oryzae causes rice blast, the most serious disease of cultivated rice. Cellular differentiation of M. oryzae forms an infection structure called the appressorium, which generates enormous cellular turgor that is sufficient to rupture the plant cuticle. Here, we show how functional genomics approaches are providing new insight into the genetic control of plant infection by M. oryzae. We also look ahead to the key questions that need to be addressed to provide a better understanding of the molecular processes that lead to plant disease and the prospects for sustainable control of rice blast.

The Essentials Of Vocabulary Teaching: From Theory To Practice, Aleidine Kramer Moeller, Olha Ketsman, Leyla Masmaliyeva

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Vocabulary is central to the learning and teaching of a second language as it affords learners access to all forms of oral and written communication that includes literature, music, and content knowledge. Word knowledge is power as words serve as building blocks to learning. Vocabulary building often occurs through reading; however, in the foreign language classroom due to the heavy concept load involved in reading a second language it is unlikely that students will acquire the essential vocabulary needed to comprehend the content and information they encounter in many texts. One of the major roles of the teacher then becomes …

Gene Expression Profiling Of Tolerant Barley In Response To Diuraphis Noxia (Hemiptera: Aphididae) Feeding, A. Gutsche, Tiffany Heng-Moss, Gautam Sarath, P. Twigg, Y. Xia, G. Lu, D. Mornhinweg

Department of Entomology: Faculty Publications

Aphids are, arguably, the single most damaging group of agricultural insect pests throughout the world. Plant tolerance, which is a plant response to an insect pest, is viewed as an excellent management strategy. Developing testable hypotheses based on genome-wide and more focused methods will help in understanding the molecular underpinnings of plant tolerance to aphid herbivory. As a first step in this process, we undertook transcript profiling with Affymetrix GeneChip Barley Genome arrays using RNA extracted from tissues of tolerant and susceptible genotypes collected at three hours, three days and six days after Diuraphis noxia introduction. Acquired data were compared …

Adaptation And Invasiveness Of Western Corn Rootworm: Intensifying Research On A Worsening Pest, Michael E. Gray, Thomas W. Sappington, Nicholas Miller, Joachim Moeser, Martin O. Bohn

Department of Entomology: Faculty Publications

The western corn rootworm, Diabrotica virgifera virgifera LeConte, is an established insect pest of maize (Zea mays L.) in North America. The rotation of maize with another crop, principally soybeans, Glycine max (L.), was the primary management strategy utilized by North American producers and remained highly effective until the mid-1990s. In 1995, widespread and severe root injury occurred in east-central Illinois and northern Indiana maize fields that had been annually rotated with soybeans on a regular basis for several decades. The failure of this cultural tactic from a pest management perspective was attributed to a behavioral adaptation by a …

Effect Of Estrus Synchronization With A Single Injection Of Prostaglandin During Natural Service Mating, Daniel Larson, Jacqueline A. Musgrave, Richard N. Funston

Nebraska Beef Cattle Reports

Records from unsynchronized cows (n = 2073; 60-day breeding season) were compared with records from synchronized cows (n = 517; 45-day breeding season) collected between 2000 and 2006. A single injection of prostaglandin F_2α was administered approximately 108 hours after bull turn-in to synchronize estrus in spring calving mature beef cows. Estrus synchronization increased the percentage of cows calving in the first 21 days without affecting pregnancy rates. However, weaning BW of calves was not significantly different. Estrus synchronization improves synchrony of calving in a shorter breeding season with similar overall pregnancy rates.

Sulfur In Distillers Grains, Sarah Vanness, Terry J. Klopfenstein, Galen E. Erickson, Kip Karges

Nebraska Beef Cattle Reports

Data were compiled from 4,143 cattle on byproduct feeding experiments. Incidence of polioencephalomalacia was small (0.14%) in diets containing 0.46% or less sulfur (S). Incidences of polioencephalomalacia increased when cattle were fed diets above 0.46% S and especially above 0.56%. Phosphoric acid successfully replaced sulfuric acid in ethanol fermentation, but the amount and cost of phosphoric acid likely limit the economic feasibility of its use.
