Financial Health Of Grain Operations After Adding A Hog Barn, Elliott James Dennis

Extension Farm and Ranch Management News

There is strong local and national interest in adding hog barns to existing row crop operations. Declining on farm income over the past several years has accelerated this interest. Grain operations cite diversifying farm income, adding another family to the farm operation, and/or replace commercial fertilizer expense as the primary reasons for adding a hog barn.

While there is industry demand to increase hog contract growing, these agreements can possess significant benefits and risks to producers. This is the second of a four part series which will discuss some financial and legal implications of adding a hog barn to an …

Human-induced atmospheric composition changes cause a radiative imbalance at the top of the atmosphere which is driving global warming. This Earth energy imbalance (EEI) is the most critical number defining the prospects for continued global warming and climate change. Understanding the heat gain of the Earth system—and particularly how much and where the heat is distributed—is fundamental to understanding how this affects warming ocean, atmosphere and land; rising surface temperature; sea level; and loss of grounded and floating ice, which are fundamental concerns for society. This study is a Global Climate Observing System (GCOS) concerted international effort to update the …

Summer Field Report, June-July 2020, W. Ross Silcock

Nebraska Bird Review

Overall, this was a fairly routine summer although birders in Nebraska know that “routine” still holds promise of a few happenings out of the ordinary. The summer season primarily examines new breeding records, range expansions, and changes in numbers, up or down. Mississippi Kites were conspicuous, a pair providing Scottsbluff’s first breeding record, but a repeating pair in Lincoln, Lancaster lost its nest in a windstorm. The first nesting record for Violet-Green Swallow for Sheridan, 7th nesting for White-winged Dove, and 9th for Short-eared Owl were all encouraging, as was an apparent family group of Northern Saw-whet Owls in Sioux. …

Robert Wolcott And The Art Of Nest Records, Thomas E. Labedz

Nebraska Bird Review

The autumn of 1894 was fortuitous for Nebraska ornithology because it is when Robert Henry Wolcott accepted an assistantship at the University of Nebraska, moving to Lincoln from the University of Michigan (Swenk 1935). Wolcott, from that point onward, made significant contributions to our knowledge of Nebraska birds (Bruner et al. 1903, Wolcott 1909, 1919), was a founding member of the Nebraska Ornithologists’ Union (NOU), and was editor for the first three Proceedings of the NOU from 1899-1902. His work expanded beyond local focus and he eventually authored a text on animal biology (Wolcott 1933). The topic of this paper, …

United States National Park Service: Publications

Executive Summary

Since Agate Springs Ranch was founded by James H. Cook in 1887, exquisite examples of transitional Miocene mammalian fauna have been found along this stretch of the Niobrara River valley. Collectively these paleontological discoveries, along with the existing archeological and historical Native American collection, were the basis for establishing Agate Fossil Beds National Monument (AGFO) as a unit of the National Park System (NPS). The fossil remains from the Harrison and Anderson Ranch formations span a short, but important, time period within the Miocene Epoch. AGFO has provided science with an intimate look into North American mammalian evolution …

Evaluating The Effect Of Non-Thermal Processing And Enzymatic Hydrolysis In Modulating The Antioxidant Activity Of Nebraskan Great Northern Beans, Madhurima Bandyopadhyay

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Great Northern Beans (GNB), a major pulse crop of Nebraska, are a rich source of dietary proteins and has the potential to release peptides with beneficial biological properties upon enzymatic hydrolysis. Thermal processing, such as boiling, is the most common way to process beans; it makes the beans palatable and also improves the accessibility of the proteolytic enzymes. Heat treatments destroy the naturally present essential bioactive components in beans like phytochemicals and could be prevented using an alternative non-thermal process. High Pressure processing (HPP), a non-thermal process and the most used alternative to thermal processing, can influence the storage proteins …

Development Of A Minority Stress Preventive Intervention For Sexual And Gender Minority Youth And Young Adults, Natalie Holt

Department of Psychology: Dissertations, Theses, and Student Research

Mental health disparities amongst sexual and gender minority (SGM) individuals are spurred by exposure to minority stressors and sustained by mediators of problems with emotion regulation, social support, and cognitive processes. Emerging clinical research suggests empirically supported behavioral health treatments can be culturally adapted to address these mental health disparities, however less work has focused on the prevention of symptoms. The present study developed a brief preventive intervention targeting mediators of the minority stress model for SGM youth and young adults aged 17 to 26. Focus groups with 8 SGM participants informed development to ensure the content and delivery of …

Energy Metabolism In Jersey Cows: Improving Our Understanding Of Energy Requirements And Utilization, Dennis Morris

Department of Animal Science: Dissertations, Theses, and Student Research

Energy is the most limiting nutrient for high producing lactating dairy cows and improving our understand of factors affecting energy supply should improve our ability to estimate net energy of lactation (NE_L), milk production, and tissue accretion. To achieve this object, firstly, three experiments were completed to determine 1) maintenance energy requirements; 2) factors affecting heat production; and 3) the relationship between urinary N and energy excretion. Three additional experiments using lactating Jersey cows were completed to evaluate energy utilization of diets varying in 1) supply of Lys and His; 2) fatty acids (FA) and …

Resilience Characteristics Of The Urban Agriculture System In Lansing, Michigan: Importance Of Support Actors In Local Food Systems, Caitlin K. Kirby, Lissy Goralnik, Jennifer Hodbod, Zach Piso, Julie C. Libarkin

School of Natural Resources: Faculty Publications

Urban agriculture is a growing movement in cities across the United States, including the post-industrial Midwest. Maintaining a resilient local food system is a challenge given the environmental, resource, and institutional barriers facing urban farmers. In this descriptive correlational study, we take an in-depth look at the demographics, farm characteristics, motivations, barriers, and resilience indicators of individuals in the urban agriculture system in Lansing, Michigan, a city of the US Midwest with a growing urban agriculture system. Survey responses (n = 92) revealed that support actors, community gardeners, and farmers have descriptive differences in their motivations, with support actors (e.g. …

Evaluating Airsoft Electric Guns For Control Of Invasive Brown Treesnakes, Adam J. Knox, Björn Lardner, Amy Yackel Adams, Robert N. Reed

United States Geological Survey: Staff Publications

Firearms are often used in lethal control of invasive vertebrates, but safety and regulatory aspects limit the circumstances under which they can be used. During August 2016 at the Brown Treesnake Project laboratory on Guam, we evaluated hobby‐grade Airsoft Electric Guns (AEGs; a lower powered, less‐hazardous, and less‐regulated alternative to firearms) for capture and control of small animals, with specific emphasis on invasive brown treesnakes (Boiga irregularis). Tests of AEGs differing in power with ammunition (plastic pellets) masses ranging from 0.20 to 0.39 g, fired at gelatin blocks from distances of 4, 8, and 12 m, showed that …

Vampire Bats: Preparing For Range Expansion Into The U.S., Michael J. Bodenchuk, David L. Bergman

United States Department of Agriculture Wildlife Services: Staff Publications

The common vampire bat apparently is expanding its range northwards in Mexico and seems poised to enter the southern United States. Climate models predict suitable habitat in the U.S. in south Texas and parts of southern Arizona. While vampire bats’ northward range expansion is not unexpected, the fact that this species brings a strain of rabies that impacts livestock and people warrants a strategic response. Annual economic damages from bats are estimated between $7M and $9M, largely associated with deaths of livestock from rabies. To prepare for the emerging rabies issue, USDA Wildlife Services programs in Texas and Arizona have …

Xipe Tótec Y El Binomio Vida-Muerte En La Cosmovisión Mesoamericana, María Montserrat Camacho Ángeles

Congreso internacional sobre iconografía precolombina, Barcelona, 2019. Actas.

El principio básico de la cosmovisión de los pueblos mesoamericanos fue sin duda la observación de su entorno natural, para ellos las deidades o fuerzas sagradas habitan en el cielo, la tierra y el inframundo, lugares que en sí mismos contienen los opuestos complementarios: vida-muerte, entre muchos otros. Este artículo explica los elementos del binomio vida-muerte que caracterizan a Xipec Tótec, deidad mesoamericana de gran relevancia.

The Mesoamerican Cosmovision’s basic principle was, to be sure, the observation of the natural environment for those cultures, the gods or goddesses or sacred forces which live on the sky, earth and the underworld; …

Elementos Chavinoides En Textiles De Paracas Y Cerámicas De Nasca, Uwe Carlson

Las imágenes plasmadas …

Characteristics Of A River Otter (Lontra Canadensis) Maternal Den In The Central Platte River Valley, Ne, Jenna M. Malzahn, Andrew J. Caven, Joshua D. Wiese

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

River otters (Lontra canadensis) encompass a broad geographic range including coastal, riverine, and lacustrine systems. However, knowledge of reproductive behavior and structural den characteristics remain relatively few in the literature, particularly in the Great Plains. Distinctions between the terms “den”, “den site”, “natal den”, and “maternal den” are often ambiguous, obscuring our understanding of river otter’s young-rearing behavior. We used observations and descriptions regarding a single maternal den site and a broad reading of the mustelid literature to propose a more standardized maternal den definition for river otters and specify hypotheses for future research. From 25 April to …

Nebraska Water Center: Faculty Publications

The objective of this study was to treat feedlot runoff by developing an ecologically sustainable, affordable, and resilient treatment system having a relatively long life span. Three horizontal flow soil biofilters were utilized in this study: 1) without earthworms and plants (Biofilter (BF)), 2) with earthworms only (Vermifilter (VF)), and 3) with earthworms and plants (Macrophyte Assisted Vermifilter (MAVF)). The experiments were conducted with a hydraulic retention time of four days using Lumbricus terestrris earthworms and Carex frankii wetland plants. The average COD removal from the BF, VF, and MAVF were 23.2–30.4%, 61.4–69.1%, and 68.3–78.1%, respectively. Average TN removal efficiencies …

Using Climate To Explain And Predict West Nile Virus Risk In Nebraska, Kelly Helm Smith, Andrew J. Tyre, Jeff Hamik, Michael J. Hayes, Yuzhen Zhou, Li Dai

National Drought Mitigation Center: Faculty Publications

We used monthly precipitation and temperature data to give early warning of years with higher West Nile Virus (WNV) risk in Nebraska. We used generalized additive models with a negative binomial distribution and smoothing curves to identify combinations of extremes and timing that had the most influence, experimenting with all combinations of temperature and drought data, lagged by 12, 18, 24, 30, and 36 months. We fit models on data from 2002 through 2011, used Akaike's Information Criterion (AIC) to select the best‐fitting model, and used 2012 as out‐of‐sample data for prediction, and repeated this process for each successive year, …
