Proposed Beef Cattle Manure Excretion And Characteristics Standard For Asae, Galen E. Erickson, B. Auvermann, R. A. Eigenberg, L. W. Greene, Terry J. Klopfenstein, Richard K. Koelsch

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

A committee was formed consisting of both animal scientists and agricultural engineers to evaluate and update current ASAE standards. An intake minus retention model was developed to estimate nutrient excretion. This approach allows users (producers, engineers, etc.) to develop site specific information based on known variables such as protein or phosphorus content of diets and cattle performance. This approach illustrates the importance of nutrition on nutrient excretion in livestock operations. Our focus is for feedlot cattle and updates excretion of dry matter (DM or total solids), organic matter (OM or volatile solids), N, P, Ca, K, Na, Mg, S, Cu, …

Estimates Of Genetic Parameters And Selection Strategies To Improve The Economic Efficiency Of Postweaning Growth In Lambs, G. D. Snowder, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

The objectives of this study were to estimate (co)variance components for growth and feed efficiency measures, and to compare selection strategies to improve economic efficiency of gain. Variance components for pre- and postweaning growth, body weight, and measures of feed efficiency were estimated from data collected on 1,047 Targhee lambs over 7 yr. Approximately 21 d after weaning, lambs were group-fed for 4 wk, with ad libitum access to a diet of 37% whole barley grain and 63% pelleted alfalfa hay. Lambs were then individually fed for 6 wk. Lambs were then returned to group feeding for another 4-wk period. …

Reviews Of Fatal Harvest: The Tragedy Of Industrial Agriculture And The Fatal Harvest Reader: The Tragedy Of Industrial Agriculture, Edited By Andrew Kimbrell, Charles A. Francis

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Fatal Harvest introduces and dispels key myths about industrial agriculture: greater efficiency; safe and nutritious food that is cheap to consumers; benefits to wildlife and environment; how biotechnology will save the world. In essays by leading proponents of a more equitable and sustainable food system, the book presents compelling evidence that alternative systems guided by an agrarian ethic will better address our food needs while protecting our natural environment and soil resources.

Wendell Berry cites the separation of people from their food supply and natural environment as a causal factor in our ready acceptance of today's industrial agriculture. When we …

Invasion Dynamics And Biological Control Prospects For Sericea Lespedeza In Kansas, Thomas Eddy, Jeff Davidson, Brian Obermeyer

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Sericea lespedeza [Lespedeza cuneata (Dum.-Cours.) G. Don], an exotic, drought-hardy perennial legume was first introduced into the United States from Japan. It was planted from the 1930s through the 1950s as a forage crop, for healing erosion scars on farmlands, establishing cover on mine spoils, and as cover for wildlife. The species range was unintentionally increased in the 1980s when seeds harvested from infested rangelands were planted on Conservation Reserve Program (CRP) acres. Sericea lespedeza has spread to extensive areas of native prairie and other lands not under cultivation in the more humid regions of the Great Plains in …

Morph-Dependent Fatty Acid Oxidation In A Wing-Polymorphic Cricket: Implications For The Trade-Off Between Dispersal And Reproduction, Anthony J. Zera, Zhangwu Zhao

Anthony Zera Publications

Although a considerable amount of information is available on the ecology and physiology of wing polymorphism, much less is known about the biochemical–genetic basis of morph specialization for dispersal versus reproduction. Previous studies have shown that the dispersing morph of the wing-polymorphic cricket, Gryllus firmus, prioritizes the accumulation of triglyceride flight fuel over ovarian growth, while the opposite occurs in the flightless morph during the first week of adulthood. In this study, we compared the in vivo rate of lipid oxidation between genetic stocks of flight-capable versus flightless morphs to determine the role of lipid catabolism in morph specialization …

Effects Of Management Practices On Grassland Birds: Greater Prairie-Chicken, W. D. Svedarsky, J. E. Toepfer, R. L. Westemeier, R. J. Robel

United States Geological Survey: Effects of Management Practices on Grassland Birds

Information on the habitat requirements and effects of habitat management on grassland birds were summarized from information in more than 5,500 published and unpublished papers. A range map is provided to indicate the breeding distribution of Greater Prairie-Chicken in the United States and southern Canada. Although birds frequently are observed outside the breeding range indicated, the maps are intended to show areas where managers might concentrate their attention. It may be ineffectual to manage habitat at a site for a species that rarely occurs in an area. The species account begins with a brief capsule statement, which provides the fundamental …

Fear And Loathing: The Modulatory Effect Of Stress On Memory Formation And Its Wildlife Management Implications, Arla G. Hile

Bird Strike Committee-USA/Canada Joint Annual Meeting: 5th (2003)

An ongoing challenge for wildlife managers is that target species habituate to or forget about hazing, even though the animals must be somewhat stressed by the hazing. Although stress and efficient memory formation/retrieval are considered to be incompatible, research suggests that the effect of stress on memory is complex. Mild and intense stress can impair memory formation and chronic stress can disrupt memory retrieval. Intermediate stress, however, actually enhances the formation of new memories, particularly long-term memories. Unfortunately, these conclusions are based data from only a very few domesticated species under highly controlled conditions. In nature the variation in baseline …

Hot Issues And Cool Rules, Bradley Lubben

Department of Agricultural Economics: Presentations, Working Papers, and Gray Literature

When President Bush signed the Farm Bill on May 13, 2002, much of the focus was on the new commodity and conservation programs and how they had changed relative to the 1996 Farm Bill. However, near the end of the Farm Bill was some language that has become one of the most contentious issues today.

Title X, Section 10816 of the Farm Security and Rural Investment Act of 2002 (2002 Farm Bill) addressed country-of-origin labeling (COOL) rules for beef, lamb, pork, fish, fruits, vegetables, and peanuts. The legislation called for voluntary guidelines to be implemented no later than September 30, …

West Nile Virus: Emerging Threat To Public Health And Animal Health, Robert G. Mclean

United States Department of Agriculture Wildlife Services: Staff Publications

West Nile virus (WNV) is in the genus Flavivirus, family Flavioiridae, and is closely related to other members of this genus: Japanese encephalitis virus in Southeast Asia, Murray Valley encephalitis virus in Australia, and St. Louis encephalitis (SLE) virus in North and South America. The principal vertebrate hosts for these arthropod-borne viruses (arboviruses) are wild birds, and the primary vectors are mosquitoes. Little clinical disease or mortality has been reported previously in wild birds from natural infection with these viruses, although significant morbidity and mortality has occurred in humans and domestic animals. West Nile virus (WNV) previously occurred …

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A new species of digenean found in the intestines of the steely-vented hummingbird Amazilia saucerrottei and the yellow-olive flycatcher Tolmomyias sulphurescens from the Área de Conservación Guanacaste, Guanacaste, Costa Rica, resembles members of the Prosthogonimidae in having a highly lobate ovary; an elongate cirrus sac containing the cirrus, pars prostatica, and internal seminal vesicle; no external seminal vesicle; two fields of extracecal vitelline follicles restricted to the area between the intestinal bifurcation and testes; and uterine loops occupying all available space in the hind body. The new species differs from all other members of the family in having genital pores …

An Individual-Based Model Of Canid Populations: Modelling Territoriality And Social Structure, William C. Pitt, Paul W. Box, Frederick F. Knowlton

United States Department of Agriculture Wildlife Services: Staff Publications

The management of canid populations has been at the forefront of wildlife management worldwide for much of the last century. Effective management depends on the ability to integrate species biology, the environmental aspects upon which those populations depend, and the factors controlling species abundance. Further, managing canid populations requires consideration of territoriality and dominance, which may have a significant effect on population dynamics. To better understand the effect of social structure on canid populations, we developed an individual-based computer model using Swarm to mimic natural coyote population dynamics. We selected the Swarm simulation environment because it is ideally suited for …

Harold W. Manter Laboratory of Parasitology: Faculty Publications

We describe two new species of leucochloridiid-like brachylaimoid digeneans parasitizing a variety of birds in the Área de Conservación Guanacaste, Costa Rica, each of which we assign to a new genus. According to Pojmanska's (Pojmanska, T. 2002a. Superfamily Brachylaimoidea Joyeux & Foley, 1930. In Keys to the Trematoda, D. I. Gibson, A. Jones, and R. A. Bray [eds.]. CAB International and The Natural History Museum, London, U.K., p. 31-36.) key for the Brachylaimoidea, we are unable to place either species in any family. One species most closely resembles members of Leucochloridium by having well-developed suckers, lacking an esophagus, and …

The paper concludes with a discussion of lessons learned from this national extension education curriculum development effort.

Functional And Comparative Genomic Analyses Of An Operon Involved In Fructooligosaccharide Utilization By Lactobacillus Acidophilus, Rodolphe Barrangou, Eric Altermann, Robert W. Hutkins, Raul Cano, Todd Klaenhammer

Department of Food Science and Technology: Faculty Publications

Lactobacillus acidophilus is a probiotic organism that displays the ability to use prebiotic compounds such as fructooligosaccharides (FOS), which stimulate the growth of beneficial commensals in the gastrointestinal tract. However, little is known about the mechanisms and genes involved in FOS utilization by Lactobacillus species. Analysis of the L. acidophilus NCFM genome revealed an msm locus composed of a transcriptional regulator of the LacI family, a four-component ATP-binding cassette (ABC) transport system, a fructosidase, and a sucrose phosphorylase. Transcriptional analysis of this operon demonstrated that gene expression was induced by sucrose and FOS but not by glucose or fructose, suggesting …

Ascaris Suum: Cdna Microarray Analysis Of 4th Stage Larvae (L4) During Self-Cure From The Intestine, Motoko Morimoto, Dante Zarlenga, Hunter Beard, Nadim Alkharouf, Benjamin F. Matthews, Joseph F. Urban Jr.

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

There is spontaneous cure of a large portion of Ascaris suum 4th-stage larvae (L4) from the jejunum of infected pigs between 14 and 21 days after inoculation (DAI). Those L4 that remain in the jejunum continue to develop while those that have moved to the ileum are eventually expelled from the intestines. Although increases in intestinal mucosal mast cells and changes in localhost immunity are coincidental with spontaneous cure, the population of L4 that continue to develop in the jejunum may counteract host protective mechanisms by the differential production of factors related to parasitism. To this end, a cDNA library …

Models With Nuclear, Cytoplasmic, And Environmental Effects For Production Traits Of Columbia Sheep, Kathryn J. Hanford, G. D. Snowder, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Statistical models (16) were compared for birth weight of 24,741 Columbia lambs recorded at the U.S. Sheep Experiment Station (USSES; 1950 to 1998). The goal was to estimate fractions of variance due to cytoplasmic line (c²; n = 590) and sire × cytoplasmic line interaction (sc²; n = 12,831) with other nuclear and environmental effects included in the model. The basic model included direct genetic (fractional variance, a²; n = 26,623), maternal genetic (m2, with direct-maternal correlation r_{am), and maternal permanent environmental (p²m ; n = 6,385) effects. The model with …}

Evaluating Shootgro 4.0 As A Potential Winter Wheat Management Tool In The Czech Republic, Z. Zalud, G.S. Mcmaster, Wallace Wilhelm

Department of Agronomy and Horticulture: Faculty Publications

Improving current cultural practices often involves more precise timing of the management activity based on crop development. Using crop simulation models to predict crop development and phenology has several problems. First, most existing models do not simulate sufficient developmental and phenological detail required to optimize selected management practices. Second, crop models normally emphasize the cultivars and conditions for the region in which they were developed, and may not generate satisfactory results when applied in new regions. Lastly, when users apply these models to new regions they often lack the specific data and knowledge of the model to adequately determine the …
