Five Decades Of Agricultural Policies In Nigeria: What Roles Has Statistics Played?, Akinboyo O. I

Bullion

All over the country and internationally, the publications of the Central Bank of Nigeria (CBN) such as the Annual Report and Statement of Accounts, the Statistical Bulletin, Economic and Financial Review, the Bullion and Nigeria: Major Economic and Banking Indicators and those of the National Bureau of Statistics (NBS) have become a veritable source of data and reference materials on Nigeria. Without basic i n f o r m a t i o n o n e c o n o m i c developments, it would be very difficult for policy makers to assess economic performances. The f o …

Evaluation Of Competition Between Turfgrass And Trees In The Landscape, Christopher A. Hendrickson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Population growth in regions of the Intermountain West has resulted in rapid growth of residential neighborhoods. In Utah, the landscapes associated with these expanding neighborhoods consume vast quantities of treated water. This is a concern in all states of the Intermountain West, as water becomes increasingly scarce. Traditionally used turfgrasses, trees and other plants in Intermountain West landscapes require significant amounts of supplemental water considering the intense sunlight, dry winds and sparse rainfall typical of the region. Characterizing the interactions between turfgrass and tree species in these landscapes can aid in the identification of candidate species that consume less nutritional …

Self-Medicative Behavior Of Sheep Experiencing Gastrointestinal Nematode Infections And The Postingestive Effects Of Tannin, Larry D. Lisonbee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Diet selection and self-medication are fundamental to the survival of all species. The abilities to choose healthy foods in response to past consequences are basic elements of evolution. This study explores self-medication regarding tannins both as a medication and as a dietary challenge. In the first study, sheep with natural parasite infections were offered a low quality supplement containing a dose of tannins considered to be therapeutic (medicine), while the control infected lambs received the same supplement without tannins (placebo). This study included a group of parasite-free lambs. The parasitized lambs ate more of the tannin containing supplement than non-parasitized …

Influence Of Supplemental Legumes That Contain Tannins And Saponins On Intake And Diet Digestibility In Sheep Fed Grasses That Contain Alkaloids, Jacob Michael Owens

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

My objectives were to determine if nutritional benefits occur when animals are offered foods with compounds -- alkaloids, saponins, and tannins - that are potentially complementary. I hypothesized that food intake and digestibility increase when lambs consume plants such as alfalfa ALF that contain saponins or birdsfoot trefoil (BFT) that contain tannins when the basal diet is endophyte-infected tall fescue (TF) or reed canarygrass (RCG) both of which contain alkaloids. I predicted that the nutritional status of lambs would be enhanced if basal diets of alkaloid-containing grasses were supplemented with ALF or BFT.

Lambs fed a basal diet of either …

Enhancing The Proportions Of Healthy Fatty Acids In Milk From Dairy Cows, Korie A.S. Nelson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Twenty cows were used in a repeated measures, block design experiment for 9 wk to determine the effects of feeding partially ruminally inert calcium salts (Ca-salts) of fish oil (FO) and a general fatty acid (FA) supplement (EnerGII) at varying levels. The effects on cow health, milk components, composition of milk FA, and sensory evaluation of milk were evaluated. Cows in the 4 treatments were fed either a control diet of 57% forage and 43% concentrate mix with EnerGII fat supplement at 1.65% of diet DM (CTL) or EnerGII in basal diet was partially replaced with (a) 0.21% …

Mechanisms Of Nutrition Bar Hardening: Effect Of Hydrolyzed Whey Protein And Carbohydrate Source, Shaun P. Adams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The influence of increasing hydrolyzed protein content on the microstructure and hardness of high protein nutrition bars was investigated to determine the mechanism of hardening during storage. Bars with various hydrolyzed protein levels were manufactured using differing ratios of 0, 25, 50, 75, 100% (wt. /wt.) of partially hydrolyzed whey protein isolate (HWPI) to an intact (non-hydrolyzed) whey protein isolate (WPI) which made up approximately 38% of the total bar composition. High fructose corn syrup (HFCS) (42%) and vegetable shortening (20%) constituted the rest of the ingredients. Accelerated aging was performed by storing bars at 32 ^oC for 36 …

A Conceptual Framework For Understanding Effects Of Wildlife Water Developments In The Western United States, Randy T. Larsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Free water can be a limiting factor to wildlife in arid regions of the world. In the western United States, management agencies have installed numerous, expensive wildlife water developments (e.g. catchments, guzzlers, wells) to: 1) increase the distribution or density of target species, 2) influence animal movements, and 3) mitigate for the loss of available free water. Despite over 50 years as an active management practice, water developments have become controversial for several species. We lack an integrated understanding of the ways free water influences animal populations. In particular, we have not meshed understanding of evolutionary adaptations that reduce the …

Synthesis And Characterization Of Lactose-Amines With Respect To Oil-In-Water Emulsion Stability, Nidhi Garg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fatty amines (hexadecyl-amine) can be esterified to lactose via Schiff-base formation at temperatures of 60° C. Extending the time of the reaction results in a darker colored product due to the Maillard reaction. Due to the amphiphilic properties of the lactose-amines, the emulsion stabilization characteristics were investigated.

In this study, synthesis of lactose-amines was done at four different heating and cooling cycles from 4 to 24 hours. Lactose-amines processed for 24 hours and 12 hours of constant heating and cooling cycles are named as 24H and 12H, respectively. Lactose-amines 4H and 8H were processed for 4 and 8 hours of …

The Improved Acre: The Besse Farm As A Case Study In Landclearing, Abandonment, And Reforestation, Theresa Kerchner

Maine History

From the vantage of the twenty-first century, it seems remarkable that farmers, working with only hand tools and farm animals, converted over half of New England’s “primeval” forests to tillage and pasture in the eighteenth and nineteenth centuries. This period was marked by transitions as farmers responded to new markets, changing family values, and declining natural resources. These forces brought an end to agrarian expansion and caused New England’s iconic pastoral landscape to begin to revert to forestland. A case study based on the former Jabez Besse, Jr. farm in central upland Maine provides a link to New England’s agricultural …

Burnt Harvest: Penobscot People And Fire, James Eric Francis Sr.

Maine History

The scientific and ethnographic record confirms the fact that in southern New England, Indians used fire as a forest management tool, to facilitate travel and hunting, encourage useful grasses and berries, and to clear land for agriculture. Scholars have long suggested that agricultural practices, and hence these uses of fire, ended at the Saco or Kennebec, with Native people east of this divide less likely to systematically burn their forests. This article argues that Native people on the Penobscot River used fire, albeit in more limited ways, to transform the forest and create a natural environment more conducive to their …

Non-Blackbird Avian Occurrence And Abundance In North Dakota Sunflower Fields, Dionn A. Schaaf, George M. Linz, Curt Doetkott, Mark W. Lutman, William J. Bleier

The Prairie Naturalist

Sunflower fields are well-documented as foraging habitat for fallmigrating blackbirds (Family Icteridae). There is, however, a paucity of information on the use of sunflower fields by non-blackbirds. We assessed non-blackbird use of 12 ripening sunflower fields in the Prairie Pothole Region of central North Dakota. From mid-August to mid-October 2000, we counted 4,129 individual birds, consisting of 22 families and 61 species, in the sample fields and within 5 m of the field edges. We saw the largest number of birds from 18 September to 27 September. The Family Emberizidae (sparrows) accounted for 26% of the species and 20% of …

The Queen Of American Agriculture: A Biography Of Virginia Claypool Meredith, Frederick Whitford, Andrew G. Martin, Phyllis Mattheis

The Founders Series

Virginia Claypool Meredith's role in directly managing the affairs of a large and prosperous farm in east-central Indiana opened doors that were often closed to women in late nineteenth century America. Her status allowed her to campaign for the education of women, in general, and rural women, in particular. While striving to change society's expectations for women, she also gave voice to the important role of women in the home. A lifetime of dedication made Virginia Meredith "the most remarkable woman in Indiana" and the "Queen of American Agriculture." Meredith was also an integral part of the history of Purdue …

Traditional Natural Resource Use And Development In Northeast Thailand, Christie Moulton

Senior Honors Projects

This paper explores the effects of development projects on traditional natural resource use in three communities in Northeast Thailand, a region known as Isan. I interviewed villagers in each community and asked them to describe their environmental perceptions, management practices and livelihood strategies. Participants described several subsistence livelihoods that have traditionally been present in Isan. These include rice farming, fishing, community forestry, and wetland use. Residents from the three communities all described various cultural activities, knowledge systems, and religious ceremonies that are closely tied to their local resources. Raising silk worms, making clay pots, and performing rituals for a spirit …

Ponderosa Pine Mortality And Bark Beetle-Host Dynamics Following Prescribed And Wildland Fires In The Northern Rocky Mountains, Usa, Ryan Stephen Davis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ponderosa pine delayed mortality, and bark beetle attacks and emergence were monitored on 459 trees for 3 years following one prescribed fire in Idaho and one wildland fire in Montana. Resin flow volume (ml) was measured on 145 fire-injured ponderosa pine 2 and 3 years post-fire. Logistic regression was used to construct two predictive ponderosa pine mortality models, and two predictive bark beetle-attack models. Post-fire delayed tree mortality was greater with the presence of primary bark beetles independent of diameter at breast height (DBH) (cm), and was greater in smaller diameter trees most likely due to direct effects of fire-caused …

Livestock Foraging Behavior In Response To Interactions Among Alkaloids, Tannins, And Saponins, Tiffanny Lyman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plant secondary compounds abound in every plant mother nature has to offer. From common garden vegetables to poisonous plants, there are secondary compounds in every plant any animal, as well as we, chooses to eat. In the past, secondary compounds were mostly considered waste products of plant metabolism, but over the last several decades research has shown that these compounds play an active role in plant and animal behavior, health, and productivity. Though often seen only in terms of their negative impacts on intake and production, we are becoming increasingly aware of their beneficial roles in plant, animal, and human …

Cytologically, Elymus species have a genomic formula of StH, StP, StY, StStY, StHY, StPY, and StWY. About 40% of Elymus …

Granivores And Restoration: Implications Of Invasion And Considerations Of Context-Dependent Seed Removal, Steven M. Ostoja

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Granivores are important components of sagebrush communities in western North America. These same regions are being altered by the invasion of the exotic annual Bromus tectorum (cheatgrass) that alters physical and biological dynamics in ways that appear to promote its persistence. This research directly relates to the restoration of B. tectorum-dominated systems in two inter-related ways. First, because these landscapes have large quantities of seeds applied during restoration, it is important to determine the major granivore communities in intact sagebrush communities and in nearby cheatgrass-dominated communities. Second, it is important to develop an understanding of patterns of seed harvest …

Simulated Browsing Impacts On Aspen Suckers' Density, Growth, And Nutritional Responses, Koketso Tshireletso

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Heavy and repeated ungulate browsing on reproductive suckers has limited trembling aspen (Populus tremuloides Michx.) regeneration on many Western landscapes. However, little is known about the specific effects of season and intensity of browsing. My objectives were to determine the effects of season and intensity of clipping (simulated browsing) on suckers’ (1) density and growth characteristics, and (2) nutritional quality and quantity.

Three randomly selected stands were clear-felled in mid-July, 2005, and fenced. Simulated browsing treatments of 0%, 20%, 40%, and 60% removal of current year’s growth were randomly applied in early, mid-, and late summers of 2006 and …

Promoting Locally Grown Foods In Schools Through Developed Classroom Curriculum And Foodservice Educational Tools, Meredith F. Carter

Senior Honors Projects

The Massachusetts’ Farm-to-School Project has worked for years to bring local farmers and school districts together. Focused on improving the markets and economic stability of farmers, while also improving the quality of foods available to students, the project implemented the first annual “Massachusetts Harvest for Students Week” during the week of September 24, 2007. As part of Harvest Week, selected schools in Massachusetts purchased and served foods grown and made by local farmers. Marketing materials were used in the participating school cafeterias, and classroom education regarding local agriculture, nutrition, and sustainability was provided. Harvest Week had the potential to improve …

Building Sustainable Agricultural Development Through Home-Grown School Feeding - The African Approach, Emmanuel Ohene Afoakwa, Linley Chiwona-Karltun

Professor Emmanuel Ohene Afoakwa

Proper nutrition is critical for optimal growth, cognitive development, general well-being and academic performance of children. Access to good nutrition either at home or through the educational system can contribute to the elimination of malnutrition and its associated health and developmental problems. In this regard, The 2005 UN World Summit recommended the expansion of local school feeding programmes, using home-grown foods where possible as one of the “Quick impact initiatives” to achieve the Millennium Development Goals, especially for rural areas facing the dual challenge of high chronic malnutrition and low agricultural productivity.

Sandhill Crane Wintering Ecology In The Sacramento-San Joaquin Delta, California, Gary L. Ivey, Caroline P. Herziger

Proceedings of the North American Crane Workshop

We studied wintering sandhill crane (Grus canadensis) ecology in 2002–2003 in the Sacramento-San Joaquin Delta of California, focusing on Staten Island, a corporate farm which was acquired by The Nature Conservancy and managed to promote sustainable agriculture that is beneficial to wildlife. Our purpose was to define habitat conservation needs for cranes, including the state-threatened greater subspecies (G. c. tabida). Research was conducted through intensive surveys by vehicle of crane foraging and roosting behavior. We estimated that about 1,500 greaters used Staten Island, which is a significant portion of the Central Valley Population of greater sandhill …

Risks, Farmers’ Suicides And Agrarian Crisis In India: Is There A Way Out?, Srijit Mishra

Srijit Mishra

Poor returns to cultivation and absence of non-farm opportunities are indicative of the larger socio-economic malaise in rural India. This is accentuated by the multiple risks that the farmer faces – yield, price, input, technology and credit among others. The increasing incidence of farmers’ suicides is symptomatic of a larger crisis, which is much more widespread. Risk mitigation strategies should go beyond credit. Long term strategies requires more stable income from agriculture, and more importantly, from non-farm sources. Private credit and input markets need to be regulated. A challenge for the technological and financial gurus is to provide innovative products …

Antidumping Duties In The Agriculture Sector: Trade Restricting Or Trade Deflecting?, Nisha Malhotra, Horatiu Rus, Shinan Kassam

Nisha Malhotra

In this paper we analyze whether U.S. Anti-Dumping (AD) duties in the agricultural sector are effective in restricting trade. More specifically, does imposition of an antidumping duty restrict imports of the named commodity or is there a diversion in the supply of imports from countries named in the petition to countries not named in the antidumping petition? We find that AD duties have had a significant impact on the imports of agricultural commodities from the countries named in the petition. However, our results also indicate that, unlike the manufacturing sector in the US, there was little trade diversion towards countries …
