Profitability Of Developing Beef Heifers On Stockpiled Winter Forages, Zachary David Mcfarlane, Chris Boyer, J. Travis Mulliniks

Journal of Applied Farm Economics

We estimate the profitability of developing heifers on one stockpiled cool-season grass and two stockpiled warm-season grasses during the winter months by comparing distributions of net present value (NPV) over an 11-year useful life. Furthermore, distributions of payback period and the break-even price for each calf over the heifer’s production life were generated for each forage species. These results are compared across forages as well as to a simulated drylot system for heifer development. Data comes from a grazing experiment in Tennessee, where heifers grazed big bluestem and Indian grass combination (BBIG), switchgrass (SW), or endophyte-infected tall fescue (TF) pastures. …

Modeling Effects Of Ecological Factors On Evolution Of Polygenic Pesticide Resistance, C. V. Haridas, Brigitte Tenhumberg

School of Biological Sciences: Faculty Publications

Widespread use of pesticides has resulted in the evolution of resistance in many insect pests worldwide, limiting their use in pest control. Effective pest and resistance management practices require understanding of the genetics of resistance and the life history of the pest. Most models for pesticide resistance assume that resistance is monogenic, conferred by a single gene. However, resistance could evolve as a polygenic quantitative trait resulting from the action of several genes, especially when pesticide dose is low. Further, fitness of the pest could be density dependent and might depend upon abiotic factors such as temperature. It is not …

Biosecurity Council Of Western Australia Annual Report 2017/2018, Biosecurity Council Of Western Australia

Biosecurity published reports

There were two key areas in which the Council focused during the year:

• environmental biosecurity; and
• the attributes required by a biosecurity ‘combat’ agency to effectively sustain a biosecurity response.

In addition, planning began for two new areas of advice to Government – biosecurity research and development; and border biosecurity.

Developing constructive advice to Government requires a comprehensive understanding of the needs and challenges of industry, Government and the community. It also requires an understanding of how changes to the biosecurity system might impact these groups and affect the State’s biosecurity status. During 2017/18 the Council continued to monitor biosecurity …

Good Riddance Rodents, Elizabeth Killinger

University of Nebraska-Lincoln Extension: Historical Materials

Holidays will be here soon and that means house guests might be coming. Take a few steps now to make sure your ‘guests’ are the ones you want at your house, not the furry, unwelcome kind. House mice are common guests once the outdoor temperatures drop. These small light gray, furry rodents have large ears and long tail. Their preferred food is grains, but they will munch on just about anything. One reason mice can be a problem once inside is due to their rapid ability to reproduce. Each year, a female mouse can produce 5-10 litters, with about 5-6 …

Micronutrient Availability In Alternative Foods During Agricultural Catastrophes, David Denkenberger, Joshua M. Pearce

Civil and Architectural Engineering Faculty Research

Several catastrophes could block the sun, including asteroid/comet impact, super volcanic eruption, and nuclear war with the burning of cities (nuclear winter). Previous work has analyzed alternate food supplies (e.g., mushrooms growing on dead trees, bacteria growing on natural gas). This was shown to be technically capable of feeding everyone with macronutrients (protein, carbohydrates, and lipids) and minerals, although economics and politics remain uncertain. The present work analyzes vitamin availability in such alternative food scenarios. The vitamin content of various alternate foods is compared to the US recommended daily allowance (RDA) as well as the average requirement defined by the …

Quantitative Appraisal Of Non-Irrigated Cropland In South Dakota, Shelby Riggs

Honors Program: Senior Projects (Public)

This appraisal attempts to remove subjectivity from the appraisal process and replace it with quantitative analysis of known data to generate a fair market value of the subject property. Two methods of appraisal were used, the income approach and the comparable sales approach. For the income approach, I used the average cash rent for the region, the current property taxes for the subject property, and a capitalization rate based on Stokes' (2018) capitalization rate formula to arrive at my income-based valuation. For the comparable sales approach, I utilized Stokes' (2018) research in optimization modeling to estimate a market value for …

A hopeful vision of the future is a world in which both people and nature thrive, but there is little evidence to support the feasibility of such a vision. We used a global, spatially explicit, systems modeling approach to explore the possibility of meeting the demands of increased populations and economic growth in 2050 while simultaneously advancing multiple conservation goals. Our results demonstrate that if, instead of “business as usual” practices, the world changes how and where food and energy are produced, this could help to meet projected increases in food (54%) and energy (56%) demand while achieving habitat protection …

Effect Of Stocking Rate On Growing Juvenile Sunshine Bass, Morone Chrysops × M. Saxatilis, In An Outdoor Biofloc Production System, Bartholomew W. Green, Steven D. Rawles, Carl D. Webster, Matthew E. Mcentire

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

The biofloc technology production system is a production intensifying management strategy used primarily for culturing tilapia and penaeid shrimp, both of which can consume the biofloc. Other fish can be grown in biofloc systems because the biofloc serves to maintain water quality, metabolizing the ammonia excreted by intensively fed fish. A dose-response study was conducted in an outdoor biofloc system to begin quantifying the stocking rate-production function for sunshine bass, Morone chrysops x M. saxatilis, advanced fingerlings. Sunshine bass (2.9 ± 0.2 g/fish) were stocked into tanks at 50 to 250 fish/m² in 50 fish/m² increments. After …

La Tierra Aquí Es Amable: Soil Macrofauna Density And Producer Perceptions Of Agricultural Soil Fertility In Cerro Punta, Chiriquí, Clara Fernandez Odell

Independent Study Project (ISP) Collection

Ethnopedology, as a subfield of ethnoecology, is the study of localized symbols and values, knowledge, and practices relating to soils. One key framework for ethnopedological studies is the Kosmos-Corpus-Praxis model, which synthesizes local and traditional ecological into three overlapping, interrelated spheres. Cerro Punta, Chiriquí is the primary vegetable-growing region in Panama, an industry highly dependent on the region’s fertile volcanic soils. Semi-structured interviews (n=8) and soil macrofauna density surveys as an indicator of soil fertility (n=9) were used to gather information regarding producers’ beliefs, knowledge, and decisions about soil fertility.

Among producers in Cerro Punta, religious beliefs and land symbolism …

The Growing Sustainable Seaweed Industry: A Comparison Of Australian State Governance Directing Current And Future Seaweed Cultivation, Meagan E. Currie

Independent Study Project (ISP) Collection

Seaweed is a critical part of natural marine ecosystems. In addition to supporting the marine environment, seaweeds are a significant global resource with nutritional, industrial and pharmaceutical applications. Seaweed also has the capacity to remediate excess nutrients in the water caused by agricultural or aquacultural waste of other organisms. Seaweed has demonstrated large potential as a remediation tool in land based polyculture and offshore Integrated Multi Trophic Aquaculture (IMTA) systems.

Seaweed is already worth over US$7 billion as a global industry, but as of 2013 over 93% of global seaweed is produced in Asia (Lorbeer, 2013, p. 718). Australia imports …
