The Russian Food And Agricultural Import Ban, Marianna Khachaturyan, E. Wesley F. Peterson

Cornhusker Economics

In 2014 the United States, European Union (EU), and several other countries imposed economic sanctions on Russia in response to its annexation of Crimea and support for separatist rebels in eastern Ukraine (Nelson, 2017; Europa, 2017). Prior to the 1990s, the use of economic sanctions to challenge the behavior of foreign governments was fairly rare as the target country could easily turn to the cold-war adversary of the sanctioning country to avoid their effects. With the end of the Cold War, sanctions, usually comprehensive in nature restricting economic relations across the board, became a major foreign policy tool. Because comprehensive …

Succession Planning And Perceived Obstacles And Attractions For Future Generations Entering Beef Cattle Production, Lee L. Schulz, Georgeanne M. Artz, Patrick J. Gunn

Journal of Applied Farm Economics

This study provides valuable insights into cow-calf producer and feedlot operator succession plans for transferring cattle operations upon exiting the industry. Across both cow-calf producers and feedlot operators, about 50% expect to be raising cattle for 10 more years or less; however, about 39% of these producers do not have a succession plan in place. Cow-calf producers view a rural lifestyle, self-employment, working with livestock, and working with family as the biggest attractions to future generations entering beef cattle production. Cow-calf producers view environmental regulations, land tax policy, and expansion of corn and soybean acres as the biggest obstacles. Feedlot …

Effects Of Transitioning From A Free Choice Tall Fescue (Lolium Arundinaceum) Hay Diet In Late Winter To A Free Choice Spring Tall Fescue Pasture Diet On Plasma Fructosamine Concentrations, Body Weight, And Body Condition Scores Of Stock Horse Mares, Paige A. Smith

Masters Theses & Specialist Projects

Approximately half of all reported laminitis cases are the result of “grass founder” (laminitis associated with long-term over consumption of lush, early spring pastures). Elevated body weights (BW), body condition scores (BCS), and blood glucose concentrations have all been associated with the onset of grass founder. Plasma fructosamine concentrations (PFC) have recently been used as an indicator of long-term (14–21 d), mean blood glucose concentrations in horses and numerous authors have reported that elevated PFC were observed in laminitic horses (Murphy et al., 1997; Keen et al., 2004; Knowles et al., 2012). This study was conducted to evaluate the long-term …

Agrarian Reform In Sumber Klampok, Emma Trainor

Independent Study Project (ISP) Collection

Agrarian reform in Indonesia is part of a movement beginning after independence was gained in 1945. Farmers have been fighting to obtain rights to their land from a government that has a history of violence, repression, and corruption for decades. Environmental, indigenous peoples’, peasant, and agrarian movements were given a legitimate, legal framework to work within after 1960 when the Basic Agrarian Law was passed, protecting the rights of the people to their land. However, during both the Old Order and especially New Order regimes, the law was often ignored by the government, and many grassroots organizations had to work …

Genomic Regions Involved In Seed Protein, Oil, And Carbohydrate Concentration In Soybean, Samantha J. Mcconaughy

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Soybeans [Glycine max (L.) Merr.] are processed for their high-quality vegetable oil and protein meal for feed, food, and industrial applications but, because of the high negative correlations between seed protein and oil concentration, it has been difficult to develop soybean lines with concomitant increases in both protein and oil. Previous studies considered only seed protein or oil concentration. This study is unique in that populations were developed using parental lines that differed in their protein, oil, and total carbohydrate concentrations in the mature seed. Two soybean populations were developed using soybean accession PI 547827 with lower total sugars as …

Strawberries (Frag X Anan) Are Bigger When Native Mason Bees (Osmia Lignaria) Are Experimentally Added To Small Farms, Laura A. Campbell

Biological Sciences Theses & Dissertations

Agriculture is the cornerstone of our economy, and pollination plays a vital role in nearly all non-wind pollinated crops. Declining honey bee populations have caused a more diligent investigation into using solitary bees for crop pollination. The native, solitary Orchard Mason Bee has shown to successfully pollinate almonds and apples, but there has been little work conducted on their effectiveness as a low fruit crop pollinator. This study assesses their effectiveness as a small strawberry farm pollinator, and preferences for nesting materials. Mason bee cocoons and nest homes made with different materials (bamboo, Phragmites, or wood) were supplemented on …

Patterns In Greater Sage-Grouse Population Dynamics Correspond With Public Grazing Records At Broad Scales, Adrian P. Monroe, Cameron L. Aldridge, Timothy J. Assal, Kari E. Veblen, David A. Pyke, Michael L. Casazza

Wildland Resources Faculty Publications

Human land use, such as livestock grazing, can have profound yet varied effects on wildlife interacting within common ecosystems, yet our understanding of land-use effects is often generalized from short-term, local studies that may not correspond with trends at broader scales. Here we used public land records to characterize livestock grazing across Wyoming, USA, and we used Greater Sage-grouse (Centrocercus urophasianus) as a model organism to evaluate responses to livestock management. With annual counts of male Sage-grouse from 743 leks (breeding display sites) during 2004-2014, we modeled population trends in response to grazing level (represented by a relative grazing index) …

Impacts Of Corn Price And Imported Beef Price On Domestic Beef Price In South Korea, Gwanseon Kim, Tyler Mark

Agricultural Economics Faculty Publications

South Korea is one of the largest beef importing countries in the world. Australia, USA, and New Zealand provide the majority of beef they import. The objective of this study is to evaluate the price relationship of Korean cattle and corn, prices of the imported beef and corn, and prices of Korean cattle and imported beef. We examine threshold points using threshold vector autoregressive (TVAR) model by assuming the presence of nonlinearity. We find that there are two thresholds in Australian beef price with first difference data. This study finds that the current Korean beef price is positively affected by …

Biotic And Abiotic Factors Predicting The Global Distribution And Population Density Of An Invasive Large Mammal, Jesse S. Lewis, Mathew L. Farnsworth, Christopher L. Burdett, David M. Theobald, Miranda Gray, Ryan S. Miller

Other Publications in Wildlife Management

Biotic and abiotic factors are increasingly acknowledged to synergistically shape broad-scale species distributions. However, the relative importance of biotic and abiotic factors in predicting species distributions is unclear. In particular, biotic factors, such as predation and vegetation, including those resulting from anthropogenic land-use change, are underrepresented in species distribution modeling, but could improve model predictions. Using generalized linear models and model selection techniques, we used 129 estimates of population density of wild pigs (Sus scrofa) from 5 continents to evaluate the relative importance, magnitude, and direction of biotic and abiotic factors in predicting population density of an invasive large mammal …

The Effect Of Lupinus Albus On Growth Performance, Body Composition And Satiety Hormones Of Male Pigs Immunized Against Gonadotrophin Releasing Factor, Karen Moore, Bruce Mullan, Jae Cheol Kim, Frank R. Dunshea

Animal production and livestock research articles

Two hundred and ninety four pigs were used with the aim to develop a dietary management strategy using Lupinus albus L. (albus lupins) to reduce the increase in feed intake and subsequent increase in carcass fatness in pigs immunized against gonadotrophin releasing factor (immunocastrates; IC males) and entire male pigs in the late finishing stage. From day (d) 0 to 28, IC males fed the control diet grew faster (p = 0.009) than entire males fed the control diet but there was no difference in growth rate between sexes for pigs fed albus lupins for 14 days pre-slaughter (Albus 14) …
