Breed Comparisons Of Weight, Weight Adjusted For Condition Score, Height, And Condition Score Of Beef Cows, J. A. Arango, L. V. Cundiff, L. D. Van Vleck

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Breeds were compared for differences in BW (n = 56,731), heights (n = 51,407) and body condition scores (BCS, n = 56,371) of 2- to 8-yr-old cows from four cycles of the Germplasm Evaluation (GPE) Program at the U. S. Meat Animal Research Center (U.S. Meat Animal Research Center). Angus, Hereford, and topcross cows from 22 breeds of sires were produced. The mixed model for repeated measures of BW, height, and BCS included random additive genetic and permanent environmental effects of the cow. Differences among crosses were significant for all traits. In general, BW, …

Environmental Contaminants Associated With A Swine Concentrated Animal Feeding Operation And Implications For Mcmurtrey National Wildlife Refuge, Matthew S. Schwarz, Kathy R. Echols, Mark J. Wolcott, Karen J. Nelson

United States Fish and Wildlife Service: Publications

Waste generated by concentrated animal feeding operations (CAFOs) may contain a variety of contaminants including nutrients, pathogens, trace elements, antibiotics, and hormones. In 2000, the U.S. Fish and Wildlife Service began to characterize CAFO contaminants in lagoons, canals, and created wetlands operated by Hastings Pork, a large swine CAFO adjacent to McMurtrey National Wildlife Refuge (McMurtrey) in Clay County, Nebraska. The created wetlands were designed to attract waterfowl; therefore, the primary purpose of this research was to evaluate whether migratory waterfowl were likely exposed to CAFO contaminants. A secondary research objective was to determine if created wetland water was suitable …

Review: Re-Evaluation Of Phosphorus Requirements And Phosphorus Retention Of Feedlot Cattle, H. C. Block, G. E. Erickson, T. J. Klopfenstein

Department of Animal Science: Faculty Publications

Phosphorus requirement recommendations for cattle are important for preventing over-feeding of P and excessive P excretion. Improved precision in managing P nutrition can reduce feedlot waste management concerns. Current beef recommendations (NRC, 1996) fail to account for absorption coefficient variation related to P source, whereas dairy recommendations (NRC, 2001) change absorption coefficients with P source. Maintenance and BW gain requirements for absorbed P do not represent underlying relationships. Maintenance P requirements reflect endogenous P loss arising from failure to reabsorb salivary P. Basing maintenance requirements on saliva P secretion and re-absorption rates should improve precision of maintenance requirement estimates. Gain …

Nf04-609 Proper Light Management For Your Home Laying Flock, Chad Zadina, Sheila Scheideler

University of Nebraska-Lincoln Extension: Historical Materials

Raising a home flock for the primary purpose of producing fresh eggs can be a rewarding and challenging venture. The main goal for egg producers is to ensure that their hens continue to produce eggs year-round. To accomplish this goal, one of the most important factors to consider, next to the overall health and nutrition of the flock, is lighting. This NebGuide discusses what a producer must do to manage proper lighting for the home laying flock.

Transmission Of Transmissible Mink Encephalopathy To Raccoons (Procyon Lotor) By Intracerebral Inoculation, Amir N. Hamir, Janice M. Miller, Katherine I. O'Rourke, Jason C. Bartz, Mick J. Stack, Melanie J. Chaplin

Zoonotics and Wildlife Disease: Publications

To determine the transmissibility of transmissible mink encephalopathy (TME) agent to raccoons and to provide information about clinical course, lesions, and suitability of currently used diagnostic procedures for detection of transmissible spongiform encephalopathies (TSEs) in raccoons, 4 raccoon kits were inoculated intracerebrally with a brain suspension from mink experimentally infected with TME. One uninoculated raccoon kit served as a control. All 4 animals in the TME-inoculated group showed clinical signs of neurologic disorder and were euthanized between 21 and 23 weeks postinoculation (PI). Necropsy examinations revealed no gross lesions. Spongiform encephalopathy was observed by light microscopy, and the presence of …

Folate Synthesis In Plants: The P-Aminobenzoate Branch Is Initiated By A Bifunctional Paba–Pabb Protein That Is Targeted To Plastids, Gilles J. C. Basset, Eoin P. Quinlivan, Stéphane Ravanel, Fabrice Rébeillé, Brian P. Nichols, Kazuo Shinozaki, Motoaki Seki, Lori C. Adams-Phillips, James J. Giovannoni, Jesse F. Gregory Iii, Andrew D. Hanson

Center for Plant Science Innovation: Faculty Publications

It is not known how plants synthesize the p-aminobenzoate (PABA) moiety of folates. In Escherichia coli, PABA is made from chorismate in two steps. First, the PabA and PabB proteins interact to catalyze transfer of the amide nitrogen of glutamine to chorismate, forming 4-amino-4-deoxychorismate (ADC). The PabC protein then mediates elimination of pyruvate and aromatization to give PABA. Fungi, actinomycetes, and Plasmodium spp. also synthesize PABA but have proteins comprising fused domains homologous to PabA and PabB. These bipartite proteins are commonly called ‘‘PABA synthases,’’ although it is unclear whether they produce PABA or ADC. Genomic approaches identified …

2004 Trafficking In Persons Report, U.S. Department Of State

Human Trafficking: Data and Documents

The State Department is required by law to submit a report each year to the Congress on foreign government efforts to eliminate severe forms of trafficking in persons. This June 2004 report is the fourth annual TIP Report. Although country actions to end human trafficking are its focus, the report also tells the painful stories of the victims of human trafficking—21st century slaves. This report uses the term “trafficking in persons” which is used in U.S. law and around the world, and that term encompasses slave-trading and modern-day slavery in all its forms.

Using Cattle To Reduce Oak Savanna Understory Shrub Abundance: Stocking Rates And Weight Gains, Janet L. Hedtcke, Joshua L. Posner, Martha Rosemeyer

Proceedings of the North American Prairie Conferences

Oak (Quercus spp.) savanna, characterized by widely scattered oaks with an understory of prairie and other specialized species, is one of the most endangered native ecosystems in North America (Nuzzo 1986, Packard and MuteI 1997). The absence of grazing and burning along with the introduction of tillage agriculture are key factors for the loss of this ecosystem. Our objective was to determine the effectiveness of rotational grazing to reduce the shrub layer in degraded oak savannas. This study took place at three sites in southwestern Wisconsin. In this paper, we report on the results of the savanna grazing on …

Adaptive Responses Of Paleoindians To Cold Stress On The Periglacial Northern Great Plains, Alan J. Osborn

Department of Anthropology: Faculty Publications

Archaeologists' cumulative knowledge about Paleoindians has grown substantially during the past two decades, and accomplishments have been impressive. I find, however, that much of the research regarding the archaeology of the Paleoindian period is primarily descriptive and highly particularistic. In this essay, I propose that our understanding of Paleoindian artifact assemblages, associated ecofactual materials, and human remains can be more meaningful within a broader biophysical context. We must ask how the archaeological record of the Late Glacial period might provide paleoanthropologists with greater insights into early hunter-gatherer anatomy, physiology, diet, health, and behavior. I propose that our understanding of hunter-gatherer …

Nf04-605 Smoking Meat And Poultry, Julie A. Albrecht

University of Nebraska-Lincoln Extension: Historical Materials

Where there's smoke, there's well-flavored meat and poultry. Using a smoker is one method of imparting natural smoke flavor to large cuts of meat, whole poultry and turkey breasts. This slow cooking technique keeps them tender, too.

Smoking is slowly cooking food indirectly in the presence of a fire. This can be done by using a "smoker," which is an outdoor cooker especially designed for this purpose. Use these simple guidelines for smoking food safely.

Relating Size Of Juveniles To Survival Within And Among Populations Of Chinook Salmon, Richard Zabel, Stephen Achord

United States Department of Commerce: Staff Publications

Understanding relationships between the size of individuals and their subsequent survival can not only provide insights into mechanisms of mortality, but can also identify traits to measure for monitoring at-risk populations. We analyzed a data set of more than 54 000 juvenile chinook salmon (Oncorhynchus tshawytscha) from 15 populations over five years. The juveniles were tagged during the summer in their freshwater rearing habitats and then recaptured at downstream sites the following spring after an extended rearing and overwintering period. We measured the length and weight of fish at tagging and computed a ‘‘condition index’’ that determined how …

Microbial Responses To In Situ Chemical Oxidation, Six-Phase Heating, And Steam Injection Remediation Technologies In Groundwater, Ann Azadpour-Keeley, Lynn A. Wood, Tony R. Lee, Susan C. Mravik

United States Environmental Protection Agency: Publications

The evaluation of microbial responses to three in situ source removal remedial technologies— permanganate-based in situ chemical oxidation (ISCO), six-phase heating (SPH), and steam injection (SI)—was performed at Cape Canaveral Air Station in Florida. The investigation stemmed from concerns that treatment processes could have a variety of effects on the indigenous biological activity, including reduced biodegradation rates and a long-term disruption of community structure with respect to the stimulation of TCE (trichloroethylene) degraders. The investigation focused on the quantity of phospholipid fatty acids (PLFAs) and its distribution to determine the immediate effect of each remedial technology on microbial abundance and …

Ground Water Recharge And Chemical Contaminants: Challenges In Communicating The Connections And Collisions Of Two Disparate Worlds, Christian G. Daughton

United States Environmental Protection Agency: Publications

Our knowledge base regarding the presence and significance of chemicals foreign to the subsurface environment is large and growing-the papers in this volume serving as testament. However, complex questions with few answers surround the unknowns regarding the potential for environmental or human health effects from trace levels of xenobiotics in ground water, especially ground water augmented with treated waste water. Public acceptance for direct or indirect ground water recharge using treated municipal waste water (especially sewage) spans the spectrum from unquestioned embrace to outright rejection. In this paper, I detour around the issues most commonly discussed regarding ground water recharge …

Antioxidant Supplementation And Nasal Inflammatory Responses Among Young Asthmatics Exposed To High Levels Of Ozone, J. J. Sienra-Monge, M. Ramirez-Aguilar, H. Moreno-Macias, N. I. Reyes-Ruiz, B. E. Del Río-Navarro, M. X. Ruiz-Navarro, G. Hatch, K. Crissman, R. Slade, R. B. Devlin, I. Romieu

United States Environmental Protection Agency: Publications

The inflammatory response to ozone in atopic asthma suggests that soluble mediators of inflammation are released in response to oxidant stress. Antioxidants may alleviate additional oxidative stress associated with photochemical oxidant pollution. This study investigates the impact of antioxidant supplementation on the nasal inflammatory response to ozone exposure in atopic asthmatic children. We conducted a randomized trial using a double-blinded design. Children with asthma ( n = 117), residents of Mexico City, were given randomly a daily supplement of vitamins (50 mg/day of vitamin E and 250 mg/day of vitamin C) or placebo. Nasal lavages were performed three times during …

The H4iie Cell Bioassay As An Indicator Of Dioxin-Like Chemicals In Wildlife And The Environment, J. J. Whyte, Christopher J. Schmitt, D. E. Tillitt

United States Geological Survey: Staff Publications

The H4IIE cell bioassay has proven utility as a screening tool for planar halogenated hydrocarbons (PHHs) and structurally similar chemicals accumulated in organisms from the wild. This bioassay has additional applications in hazard assessment of PHH exposed populations. In this review, the toxicological principles, current protocols, performance criteria, and field applications for the assay are described. The H4IIE cell bioassay has several advantages over the analytical measurement of PHHs in environmental samples, but conclusions from studies can be strengthened when both bioassay and analytical chemistry data are presented together. Often, the bioassay results concur with biological effects in organisms and …

Bovine Tuberculosis In Swedish Farmed Deer: Detection And Control Of The Disease, Helene Wahlström

Michigan Bovine Tuberculosis Bibliography and Database

Bovine tuberculosis (BTB) was introduced into Swedish farmed deer herds in 1987. Epidemiological investigations showed that 10 deer herds had become infected (July 1994) and a common source of infection, a consignment of 168 imported farmed fallow deer, was identified (I).

As trace-back of all imported and in-contact deer was not possible, a control program, based on tuberculin testing, was implemented in July 1994. As Sweden has been free from BTB since 1958, few practicing veterinarians had experience in tuberculin testing. In this test, result relies on the skill, experience and conscientiousness of the testing veterinarian. Deficiencies in performing the …

Energy And Nitrogen Utilization Of Corn Rootworm Protected Corn (Event Mon 863) And Similar Non-Transgenic Corn In Young Pigs, Robert L. Fischer, Phillip S. Miller

Nebraska Swine Reports

This experiment was conducted to compare the nutritional value, measured by digestible and metabolizable energy, and nitrogen digestibility in young pigs fed either corn rootworm protected test corn (event MON 863, RX740CRW) or a genetically similar non-transgenic control corn (RX740). The experiment used 12 barrows with an initial body weight of 74.5 lb. The pigs were housed individually in stainless steel metabolism crates and were randomly allotted to one of two corn treatments, either corn rootworm protected corn or non-transgenic control corn. Diets were formulated to contain 97.5% of test or control corn and 2.5% minerals and vitamins. The duration …
