Department of Agricultural Economics Faculty Publications

The egg industry has transitioned, or is in the process of transitioning, from conventional cages to alternative hen housing systems in response to legal changes in many states across the United States (US). However, consumers find it is increasingly difficult to understand the details behind those labels and specific attributes conveyed. There are multiple hen housing options with a wide range of costs and impacts on hens, workers, and the environment. This research furthers the understanding of US public perceptions and attitudes related to hen housing systems and corresponding animal welfare, worker, economic, and environmental effects. Results reveal that the …

Is Mycoplasma Bovis In Sand Bedding Infectious To Dairy Calves?, David J. Wilson, Thomas J. Baldwin

All Current Publications

Mycoplasmas are unusual bacteria that can infect all ages of cattle, and can cause arthritis, pneumonia, and death. Infected dairy cows may also contract mastitis, metritis, or virtually cease milk production. The most common mycoplasma affecting cattle is M. bovis; there are several other Mycoplasma spp. as well. Because standard microbial culture methods do not isolate Mycoplasma spp., special laboratory methods are needed for diagnosis. Mycoplasma spreads by inhalation and respiratory secretions and also at milking time via contaminated inflations in milking units. Mycoplasma spp. have also been detected in straw, sand, recycled manure, and other bedding, often associated …

Department of Agricultural Economics Faculty Publications

Dogs are a popular companion animal in the United States; however, dog acquisition is often a contentious subject. Adoption is often cited as an ethical and popular method of acquisition but interpretation of the term ‘adoption’ may vary. In a nationally representative survey of the U.S., 767 respondents were asked questions regarding their opinions of dog acquisition and adoption. Within the sample, 45% had a dog; of those, 40% had adopted a dog, and 47% visited a veterinarian once a year. A best-worst choice experiment, where respondents were asked to choose the most ethical and least ethical method of acquiring …

New Market Opportunities And Consumer Heterogeneity In The U.S. Organic Food Market, Gwanseon Kim, Jun Ho Seok, Tyler B. Mark

Agricultural Economics Faculty Publications

This paper investigates what factors and characteristics of organic consumers affect annual organic food expenditure by using Nielsen’s consumer panel dataset from 2010 to 2014. To be specific, this paper explores new marketing opportunities by investigating organic consumer heterogeneity in different household income levels by utilizing the multilevel model. Findings in this study will contribute to the previous and existing literature in three-folds. First, we find that the organic consumers are more heterogeneous in the high-level of income groups (approximately above $60,000), as well as the low-income households between $35,000 and $45,000. This finding demonstrates that the income levels above …

The Rationale For Taxpayer Support For Primary Industry Research And Innovation In Western Australia, Ross Kingwell

Research Reports

During the 2000s a common view in government circles was that governments were over-investing in primary industry research and innovation. In agreement with this view, the Western Australian (WA) government lessened its support for primary industry research and innovation over the last decade. The impacts of this reduced support are seen clearly in the Department of Primary Industries and Regional Development (DPIRD). In 2008–09 its agricultural staff count was 1518, yet by the end of 2017–18 this will be under 800, with remaining staff working mostly in regulation, biosecurity and corporate services rather than research. So great has been the …

An Assessment Of The Greatest Impacts On Distribution Uniformity For Drip And Micro Irrigation, Brooke Ashley Worden

Master's Theses

Using the Cal Poly Irrigation Training and Research Centers (ITRC) drip/micro evaluation program, global, or system, DU_lq is computed by combining the component DU_lq values of: pressure variation, uneven spacing between emitters, unequal drainage and “other” causes. “Other” causes include plugging, wear and manufacturing coefficient. The program also computes what percentage of the non-uniformity is due to each component. Burt (2004) showed that over 95% of the non-uniformity is due to “Other” causes and pressure differences. This thesis looks at what specifically in those components is driving the non-uniformity by analyzing various equipment and field practices and their …

The Use Of Smart Devices For The Detection Of Aflatoxin In Ground Corn Feeds, James Salveo L. Olarve, Gil Nonato C. Santos, Karen Doniza, Mary Gillian Santos

Angelo King Institute for Economic and Business Studies (AKI)

Aflatoxin contaminates agricultural commodities, plants or animal-derived food, in warm and humid conditions primarily in tropical countries such as the Philippines. Although the type and degree of contamination are dependent on its concentration, its effect becomes critical when biomagnified. In this study, a rapid, simple, and portable detection was developed. A smart-device sensor was used to measure the pH of the samples with aflatoxin and compared it with the pH of pure samples. Concentrations in parts per billion (ppb) were calculated for each of the samples from the obtained pH readings; Cyclic voltammetry was also conducted to further study the …

The fruit were stored for 3 weeks at 5 °C and then for 1 week at 20 °C. After storage, the fruit from the top and bottom layers were separately evaluated for quality. The development of stem-end rind breakdown (SERB) was the main cause of quality loss and was greater …

Confirming World-Wide Distribution Of An Agriculturally Important Lacewing, Chrysoperla Zastrowi Sillemi, Using Songs, Morphology, Mitochondrial Gene Sequencing, And Phylogenetic Reconstruction, Zoe Mandese

Honors Scholar Theses

The Chrysoperla carnea-group of green lacewings is a cryptic species complex. Species within the group are morphologically similar, yet isolated from one another via reproductive mating song. Chrysoperla zastrowi, a species within the carnea-group, is currently described with a distribution ranging from South Africa to the Middle East and India. However, recent collections of carnea-group lacewings from Guatemala and California were preliminarily identified as Chrysoperla zastrowi based upon similarities in their vibrational courtship songs. This analysis aims to place six specimens, collected by collaborators in Guatemala, Armenia, Iran, and California, into a pre-existing phylogeny of the …

Effects Of Stand Structure, Browsing, And Biophysical Conditions On Regeneration Following Mountain Pine Beetle In Mixed Lodgepole Pine And Aspen Forests Of The Southern Rockies, Kristen A. Pelz, Frederick W. Smith

Aspen Bibliography

Aspen (Populus tremuloides) and lodgepole pine (Pinus contorta var. latifolia) co-occur in the southern Rocky Mountains (USA), where mountain pine beetle (MPB, Dendroctonus ponderosae) has caused extensive lodgepole pine mortality since the late 1990s. Both species excel in post-disturbance high-light environments, but lodgepole pine has generally been thought to establish poorly on undisturbed seedbeds, and aspen suckering may be inhibited by intact aspen overstory. We ask whether lodgepole pine and aspen will regenerate in sufficient quantities to revegetate these forests. We visited a random sample of aspen and lodgepole pine stands across the affected landscape …

Studies On Α-Lipoic Acid Molecularly Imprinted Membrane And Its Antioxidant Properties, Yang Bowen, Chen Yuqin, Zhu Qiujin

Food and Machinery

Thermo-sensitive α-lipoic acid molecularly imprinted polymers (ALA-MIPs) were synthesized through pre-polymerization using α-lipoic acid as a functional monomer and N-vinylcaprolactam (NVCL) as both thermo-sensitive monomer and functional monomer. Poly(acrylonitrile) (PAN) and Poly(vinylidene fluoride) (PVDF) were used as the main raw material to synthesis molecularly imprinted membranes through the heterogeneous particle-filling method by adding ALA-MIPs. The morphology of the molecularly imprinted membrane(MIM) was investigated by scanning electron microscopy. The mechanical properties, hydrophilic properties, water absorption abilities, and ALA release properties of the membrane were also investigated. The results show that the PVDF membrane has better mechanical properties and hydrophobic properties when …

Fall crops are coming up, and they’re amazing. We started digging up the potatoes today and it is so crazy to see how many potatoes can grow from planting a chunk of potato with a couple of eyes on it! Some of these plants have two pounds of potatoes growing off of them. The pumpkins are already enormous, and the butternut squash are still ripening but are really good-sized already. The melons are taking longer than expected, but look great. Our one warm-season failure seems to be the eggplant- but watch them produce like crazy now that I’ve said that. …

Development And Testing Of A Standardized Method To Estimate Honeydew Production, Melinda L. Moir, Michael Renton, Benjamin Hoffmann, Mei Chen Leng, Lori Lach

Biosecurity Research Articles

Honeydew production by Hemiptera is an ecologically important process that facilitates mutualisms and increases nutrient cycling. Accurate estimates of the amount of honeydew available in a system are essential for quantifying food web dynamics, energy flow, and the potential growth of sooty mould that inhibits plant growth. Despite the importance of honeydew, there is no standardized method to estimate its production when intensive laboratory testing is not feasible. We developed two new models to predict honeydew production, one based on insect body mass and taxonomic family, and one based on body mass and life stage. We tested the accuracy of …

Early Events In Japanese Encephalitis Virus Infection: Viral Entry, Sang-Im Yun, Young-Min Lee

Animal, Dairy, and Veterinary Science Faculty Publications

Japanese encephalitis virus (JEV), a mosquito-borne zoonotic flavivirus, is an enveloped positive-strand RNA virus that can cause a spectrum of clinical manifestations, ranging from mild febrile illness to severe neuroinvasive disease. Today, several killed and live vaccines are available in different parts of the globe for use in humans to prevent JEV-induced diseases, yet no antivirals are available to treat JEV-associated diseases. Despite the progress made in vaccine research and development, JEV is still a major public health problem in southern, eastern, and southeastern Asia, as well as northern Oceania, with the potential to become an emerging global pathogen.
