A Board Game Simulator For Promoting System Thinking For Sustainable Pastoralism Among Maasai In Southern Kenya, Jacob Loorimirim Mayiani

Masters Theses, 2010-2019

A culturally-anchored board game simulator named ERAMAT! was created in cooperation with faculty members and members of the Maasai community and then piloted with US students and members of Maasai communities in southern Kenya during the summer of 2012. The game provides an alternative to a computer-based simulator, and hence provides a culturally credible simulation of the system dynamics associated with an accelerating boom/bust cycle of drought and hunger in the region. Factors driving the phenomena include greatly increased population densities, pastoralist cultural values, evolving pastoral practices, the ebb and flow of the semi-arid environment in which Maasai pastoralists live, …

Providing More—And Better—Food By 2050, John W. Finley

Agricultural Research Magazine

The world in 2050 is predicted to have 9 billion people, who will differ in almost every way but one: They will all need to eat on a daily basis.

Their nutritional needs will be similar, too. Nutrition means eating, eating means food, and food means agriculture. Many people speak of the increased food needed for 9 billion, but in reality, the increased need is for nutrition. Thus, the world of 2050 will force a melding of two disciplines that have diverged in recent years—agriculture and nutrition.

We need to change our focus. We need sustainable nutrition as much as …

Olives! Scientists Take A New Look At An Ancient Crop, Talwinder S. Kahlon, Jiann-Tsyh Lin, Rebecca R. Milczarek, Mendel Friedman, Marcia Wood

Agricultural Research Magazine

Though the price makes you wince, you might just buy that bottle of your favorite olive oil anyway. Perhaps it’s exactly what you want for the salad dressing you’re making tonight and for your special stir-fry on the weekend. But are you really getting what you paid for?

A bottle proclaiming that it is olive oil might actually include another, lessexpensive vegetable oil derived from, for example, safflower or canola. Mislabeling is of concern not just to shoppers, retailers, and chefs, but also to America’s olive growers, olive oil processors, and more—especially those newly entering the U.S. olive oil market. …

Mapping The Way To Even Healthier Rice, Shannon Pinson, Jan Suszkiw

Agricultural Research Magazine

With the aid of high-tech tools, Agricultural Research Service and collaborating scientists are closing in on the genes in rice that regulate the uptake and storage of important minerals—a pursuit that could bolster the nutritional value of this cereal grain crop as a staple food for roughly half the world’s population.

Ultimately, the team envisions biofortifying rice using traditional plant breeding methods to develop new varieties whose kernels (grain) boast exceptionally high concentrations of essential minerals, including zinc, iron, and calcium.

Rice is a mainstay of the human diet for good reason. It is a rich source of energy, free …

Nematode-Filled Capsules Tested Against Corn Rootworms, Jan Suszkiw

Agricultural Research Magazine

Each spring, the western corn rootworm (Diabrotica virgifera) awakens from its winter slumber to wreak havoc on corn crops across the United States. The pest emerges in larval form, hatching from small white eggs deposited beneath the soil and causing significant feeding damage to the grain crop’s roots. The toll on U.S. farmers: an estimated $1-2 billion annually in yield losses and chemical control.

European growers face a similar threat from the pest, which was first reported in a corn field near the Belgrade international airport in Serbia (formerly Yugoslavia) in 1992, but is presumed to have arrived …

Getting Hooked On Farmed Salmon: A Good Source Of Omega-3s, Susan Raatz, Matthew Picklo, William Wolters, Rosalie Marion Bliss

Agricultural Research Magazine

Nearly 85 percent of seafood enjoyed by U.S. consumers is imported, and almost half of that is farm raised through a process called “aquaculture,” according to the National Aquaculture Association, based in Pine Bluff, Arkansas. In 2011, the United States imported $16.6 billion of seafood and exported $5.4 billion, a difference of $11.2 billion.

As the world’s population grows and demand for seafood increases, many seafood species are overfished or fully exploited. That means the world’s oceans cannot turn out more fish than are currently being produced. As the ceiling is being reached on seafood availability from the wild, U.S. …

New Bioenergy Yeast Is An Overachiever, Zonglin Lewis Liu, Ann Perry

Agricultural Research Magazine

There's a lot that can be done with a corn cob after the kernels have been removed. Farmers leave the cobs on the field to boost soil quality. Enterprising cooks use the cobs to make jelly. In China, the sugar xylose is extracted from the cob for industrial uses.

Liu worked with technician Scott Weber and supervisory microbiologist Michael Cotta on this project. All three researchers are in the Bioenergy Research Unit at the National Center for Agricultural Utilization Research in Peoria, Illinois.

The team started the project with a strain of yeast that had been identified in earlier studies …

The purpose of this project was to create a video designed to educate the public about chicken egg storage and refrigeration. The information in the video was based on a research experiment performed by the author, which was designed to measure the chronological decline of internal egg quality over a ten-week period. By creating an educational video about the longevity of chicken eggs, it is hoped that consumers will learn to keep their eggs past their sell-by dates. This project includes an educational video as well as an outline for a research project.

Perceptions Of Kentucky Secondary School Principals About Agricultural Education Programs: A Comparison Of Schools With And Without Agricultural Education Programs, Andy Joe Moore

Dissertations

Countless research suggests that secondary agricultural education programs could benefit all students regardless of school characteristics and geographic location, yet many secondary schools have yet to include agricultural education as part of their curricular offerings. In response, numerous studies have been conducted in recent years throughout the United States regarding how secondary agricultural education programs are perceived by school leaders. For the first time, this study sought to shed light on how secondary principals in Kentucky perceived agricultural education programs. Considered in this study, were how secondary principals with agricultural education in their schools perceived those programs differently than secondary …

Assessment Of Introduction Pathway For Novel Avian Influenza Virus Into North America By Wild Birds From Eurasia, Ryan S. Miller, Steven J. Sweeney, Judy E. Akkina, Emi K. Saito

Zoonotics and Wildlife Disease: Publications

A critical question surrounding emergence of novel strains of avian influenza viruses (AIV) is the ability for wild migratory birds to translocate a complete (unreassorted whole genome) AIV intercontinentally. Virus translocation via migratory birds is suspected in outbreaks of highly pathogenic strain A(H5N1) in Asia, Africa, and Europe. As a result, the potential intercontinental translocation of newly emerging AIV (e.g. A(H7N9) from Eurasia to North America via migratory movements of birds) remains a concern. An estimated 1.48 to 2.91 million aquatic birds, principally Anseriformes (ducks, geese, and swans) and Charadriiformes (gulls, terns, and shorebirds) move annually between Eurasia and North …

Food Defense Among Meat Processing And Food Service Establishments In Kentucky, Morgan Webb-Yeates

Masters Theses & Specialist Projects

Agroterrorism is the deliberate introduction of a plant or animal disease with the
goal of causing fear, economic instability, illness, or death. After the 2002 terrorist
attacks on the World Trade Center, the security of the food supply is of increasing
concern to the United States. A major incidence of agroterrorism or food tampering would have far reaching impacts on the economy and public health. The first objective of this project was to determine knowledge and concern of agroterrorism in meat processing facilities in Kentucky, and to determine knowledge and concern of food tampering and food defense in food service …

Effects Of Integrating Mathematical Concepts Into An Animal Science Curriculum, Andrea Rae Clark

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nationwide, mathematical scores have been a topic of concern among elementary and secondary educators for many years. Teaching contextualized math has been found to be effective and includes providing a direct application to real-life scenarios rather than teaching linear equations and algebraic principles outside of their application.

A study was conducted measuring the effects of integrating mathematical skills in an animal science curriculum. All students were taught a unit of instruction about animal nutrition and feeding. The control group received a typical nutrition unit and the treatment group received the same unit of instruction with the addition of mathematical skill …

Nutritional And Economic Analysis Of Small-Scale Agriculture In Imbabura, Ecuador, Jake Erickson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Intervention projects in the developing world normally aim to satisfy either the nutritional needs of a group, or advancing the economic stability, but not both. One of the many issues that may arise by narrowly focusing and creating an aid program is that although a group may be fed, they are not equipped to mitigate risks that will arise after project completion and thus continue or revert back to a malnourished state. A bridge is required to join the economic and nutritional programs to create aid interventions that are sustainable past the point of donor separation.

This paper proposes the …

Evidence Of Agrarian Urbanism: Land Use Preferences Of Residents Living On Small Acreage Farms Or Large Lots With Animal Rights In Cache Valley, Utah, Laurie B. Hurst

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Until the last half century, land development patterns in the Intermountain West were designed after the Mormon settlement pattern. With its gridiron streets and in-town farmsteads, this pattern gave families the opportunity to grow crops and raise a few animals on their one acre or less in town, with the added advantage of having a social life. In many places over the last century, cities have grown, small farms have dwindled, and large farms have been pushed to the fringe. However, in the Intermountain West the agrarian tradition continues with a number of families who grow gardens and raise animals …

Dogs, Pine Trees, And Carbs, Neil P.J. Price, Marcia Wood

Agricultural Research Magazine

Carbohydrates from a perhaps surprising source—pine trees—may have beneficial effects on dogs’ digestive-system health, according to collaborative studies by Agricultural Research Service, university, and corporate scientists.

The carbs, predominantly a group known as “GGMOs”—short for galactoglucomannan oligosaccharides—are a key ingredient in Previda, an all-natural dietary ingredient marketed to makers of pet food, aquaculture feed, and other animal-nutrition products.

ARS chemist Neil P.J. Price began his studies of these fiber-rich carbs in 2007, working under the auspices of a cooperative agreement with Temple-Inland, a Texas-based producer of lumber, fiberboard, and other wood products made from loblolly, longleaf, and other kinds of …

Nourishing America’S Preemies Scientists Confront The Challenges Of Iv Feeding, Douglas G. Burrin, Marcia Wood

Agricultural Research Magazine

Each year, more than a half-million infants are born prematurely in the United States. Many of these preemies, particularly those whose tiny digestive systems are simply too underdeveloped to handle mother’s milk or infant formula, may need to be nourished exclusively via intravenous feeding, known as “total parenteral nutrition,” or TPN.

TPN solutions, usually administered at the hospital for anywhere from a few days to a month or more, provide essential nutrients broken down into a very basic form. This liquid is gently and continuously infused into the infant’s bloodstream, completely bypassing the digestive tract.

“TPN helps save the lives …

Viral Infection In Sheep Linked To Gene, Michael P. Heaton, Kreg A. Leymaster, Sandra Avant

Agricultural Research Magazine

The discovery of a gene associated with a persistent viral infection that causes an incurable disease—ovine progressive pneumonia (OPP)—in sheep has led to the development of a genetic test that can be used to help reduce the impact of the disease.

A slow-acting, wasting disease, OPP affects millions of sheep worldwide and is one of the most costly diseases to producers in North America. Previous research revealed that 36 percent of sheep operations and 24 percent of sheep tested in the United States were infected with ovine progressive pneumonia virus (OPPV)—lentivirus strains that target the immune system and cause OPP. …

Small Burnet (Sanguisorba Minor Scop.) Response To Herbicides Applied Postemergence, Ryan Lee Nelson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Small burnet is a relatively unknown plant that is commonly used in North America. It is a hardy, relatively long lived forb native to Eurasia that grows well in most of North America. It is considered to be excellent forage for livestock and wildlife and because of its evergreen nature there is interest in its use to extend grazing of pastures and rangelands into late fall and winter.

Popular sources reference its use in salads, ice drinks, with cream cheese, as a desirable garnish due to its distinct cucumber aroma and flavor. It is also reported to be a superb …
