▼ Past research indicates that the profitability of a feedlot can be determined by both production and economic factors. This study seeks to evaluate specific production and economic factors in order to deduce which of these factors has the greatest impact on profitability. This study uses economic and production data from feedlots located in the West, Midwest, and Southwest United States. Results of this study indicate that economic factors such as cattle prices and feed costs have the greatest effect on profitability. It was also found that production variables including dry matter intake, dry matter conversion, average daily gain, days on feed, percent of pen that grade quality Prime and Choice, and percent of pen that are dark cutters have a large impact on the variation of profit. Using these factors, production functions were created to determine optimal days on feed and optimal out-weights to maximize profitability. These production functions indicated that as prices increased for corn and feeder cattle, profit decreased and feedlot managers should feed fewer days to minimize profit losses. As the price of fed cattle increased, the results suggest that feedlot managers should feed cattle longer to maximize profit.

▼ A meta-regression analysis was conducted to more clearly identify the control strategies that influence the economic impacts due to a foot-and-mouth disease (FMD) outbreak in North America. Models were specified accounting for differences across control strategies (culling rate, vaccination, improving in traceability, and delayed detection) and epidemiological models that are used to simulate FMD outbreaks under different assumption. Results of the analysis show that applying vaccination-to-die policies increases the national loss but it might be a method to contain the disease when spreading widely. Delayed detection of infected animals is the most influential factor that impacts economic losses, however, by improving traceability system, the economic impacts can be reduces by localizing and depopulating latent or potentially infected animals before they allow disease to spread.

▼ Producers look for various traits in seedstock bulls to enhance their herds and will often pay a premium for those traits. One particular physical trait which is of interest to producers in the mountainous western United States is for cattle that can thrive at a high altitude. Cattle in this environment can be prone to developing High Altitude Disease (HAD) which has been shown to cause weakness, lethargy, and death. Pulmonary Arterial Pressure (PAP) is a test used to detect the likelihood of an animal of developing HAD. The test provides a score from 30 to 130 with scores over 45 indicating an animal is more likely to develop the disease.
Colorado State University specializes in cattle genetics; and in particular, manages a herd that has low PAP scores, strong early growth, fertility, and maternal ability. The center holds an annual auction to sell their yearling bulls each spring. Data was collected from three years of sales (2011, 2012, and 2013), and hedonic models were estimated using ordinary least squares (OLS) to determine the value of simple performance measurements (SPM), expected progeny differences (EPD), and marketing factors of the yearling bulls sold at these auctions. In one model, a continuous variable for PAP score was found to be significant and have a negative relationship with sale price. In a second model, a dummy variable for a PAP score under 46 was shown to be significant and have a positive relationship with sale price. In a third model using standardized continuous variables, PAP score was shown to have the most influence on sales price, followed by EPD for yearling weight, frame score, and EPD for stayability. The results suggest that producers are willing to pay a premium for a low PAP score.

▼ This dissertation examines the prospects of sustainable agricultural intensification by rural farming households in Ethiopia. Although widely accepted as the new paradigm for agricultural development in sub-Saharan Africa, several research and empirical questions still surround the concept of sustainable intensification, particularly its operationalization. Efforts to promote, measure and monitor progress towards sustainable intensification are hampered by the lack of quantifiable indicators at the farm level, as well as the uncertainty over the relationship between intensification and sustainability. This dissertation contributes to this knowledge gap by examining the relationship between agricultural intensification and sustainability, with a view to determine if sustainable paths of agricultural intensification are possible within the smallholder farming systems of Ethiopian highlands. To help better execute the research inquiry, and achieve the main goal of this study, the themes of this dissertation are addressed through three separate but interrelated essays, on top of the introductory and conclusion chapters. The first essay, presented in chapter two, examines the drivers and processes shaping agricultural intensification by smallholder farmers. This chapter contributes to the literature by providing evidence of how agricultural intensification depends on a wide range of factors, whose complex interactions give rise to different intensification pathways. The implication is that, even in a region that is undergoing the process of agricultural intensification, households are likely to respond differently to intensification incentives and production constraints, and thus pursue different paths of agricultural intensification. The second essay, chapter three, develops a methodological framework for defining elements of sustainability based on observed, context-specific priorities and technologies. Farm-level indicators of agricultural sustainability are developed using insights drawn from literature, and adapted to the Ethiopian context through consultations with agricultural experts and key stakeholders in the agricultural sector. A Data Envelopment Analysis (DEA) framework is applied to synthesize the selected indicators into a relative farm sustainability index, thus reducing subjectivity in the sustainability index. A generalized linear regression model applied on the computed sustainability scores shows that farm size, market access, access to off farm income, agricultural loans, access to agricultural extension and demonstration plots are key drivers of agricultural sustainability at the farm level. Despite being applied to the Ethiopian context; the methodology has broader policy implications and can be applied in many contexts. The third essay, chapter four, examines the relationship between agricultural intensification and relative farm sustainability, and identifies four clusters of farmers depending on their relative levels of intensification and sustainability. The main thrust of this essay is to…

▼ Highly pathogenic disease can affect trade between countries. How health officials in an affected country manage a disease event can affect the potential impacts of a disease event. Highly pathogenic avian influenza (HPAI) and exotic Newcastle disease (ND) are two diseases that affect poultry industries and it is important to understand the ramifications of having an event of either of these diseases. The implications of an outbreak are first felt internally, where domestic markets are affected through changes in stocks and price changes. Secondly, the impacts are external. These external impacts can come in the form of potential trade bans from importing countries as a result of health concerns. This work analyzes both of these impacts to provide a holistic understanding of a HPAI or ND event on U.S. poultry markets. The first essay models the U.S. egg layer industry to estimate the producer and consumer impacts of a regionalized disease outbreak to compare the benefits of using business continuity during a disease event. The estimated value of business continuity during a hypothetical disease event is $13.6 million in two quarters. The second essay then determines the factors that affect trade quantities for exporting countries including the effect of a disease outbreak on the quantity traded. Highly pathogenic avian influenza is found to change the composition of trade between different product categories, providing exporters a better understanding of how product mixture might change during a disease event. The third essay builds on the methodology of the second essay to compare modeling properties of an improved estimator in determining the factors that affect bilateral trade quantities. There are small efficiency gains captured by using a systems approach, but data are limited due to the methodology, causing a tradeoff between usable bilateral trade data and efficiency gains in estimation. The three essays combined provide an overview of how a highly pathogenic disease outbreak can affect U.S. markets for poultry products both domestically and internationally.

▼ The equine industry, from an economic perspective, is largely understudied with much of the existing research conducted on economic contribution studies (College of Agriculture, Food and Environment,
University of Kentucky, 2013; Rephann, 2011; Conners et al., 2011; Deloitte Consulting LLP, 2005; Swinker et al., 2003) and the Thoroughbred sector of the industry (Maynard and Stoeppel, 2007; Poerwanto and Stowe, 2010; Plant and Stowe, 2013). Few studies have investigated the economic impacts of equine disease and/or equine disease outbreaks to individuals, regions, or states (USDA-APHIS-VS, 2003; Conners et al., 2011). This collection of studies aims to contribute to existing equine economic research by investigating the impacts of equine disease outbreaks in a variety of ways that complement and reinforce each component part’s findings. Equine owner’s experience two major types of costs when their horse has an infectious disease: direct costs of treating the horse for the disease (e.g., veterinarian expenses) and indirect costs (e.g., lost daily use of the horse). Utilizing survey data collected nationwide, estimates of daily horse use value (DHUV), as well as, respondent preferences regarding disease treatment options was obtained. Results suggest that the average horse owner is willing to pay between 11.99 and 17.84 to reduce the number of non-use (rest) days required. Respondents showed preferences for administration of oral medications over intramuscular injection medications, all else equal, and a preference for treatments requiring fewer number of doses per day. To expand upon the estimated DHUV, a survey of equine owners/riders/trainers, etc. provides data to estimate the lost DHUV experienced by respondents when their horse develops a disease as it relates to equine events. Results suggest DHUV, of those surveyed, to be impacted by income level, the frequency of equine events attended by distance and whether a planned equine event is upcoming or not. An important contribution to the previous study estimating daily use values of equids is the incorporation of a timing aspect related to equine events (i.e., length of time until a planned equine event). This generated the expected results and informed the conclusion that DHUV does vary as days until the next event decreases. As anticipated, equine owners assigned a higher daily value the use of their horse when an event was three weeks away compared to when there was no immediate event, and more specifically, the daily value increased by a difference of 4.14. In addition to effects on the equine owners, there are economy-wide implications from equine disease outbreaks as well. As one example, equine events drive tourism for the local economies for locations where th+H4ey are held, by generating revenue to multiple local industries. The economic impact from tourism activities surrounding equine events includes monies spent by event spectators, exhibitors and volunteers who reside outside the region and the “inflow of non-resident monies”…

▼ Unwanted horses are a significant problem for policymakers and equine stakeholders. Alternatives for resolving the problem are unclear, in no small part because it is difficult to disentangle the relative importance of several causes. This study considers the impact of several factors on the problem by quantifying their influence on horse auction prices. Analysis segments horses into investment and recreational markets, high value and low value equine segments and by gender. Results suggest the slaughter ban impacts auction prices of some segments significantly, but other impacts are negligible.

▼ Variation exists within beef cuts produced by U.S. beef packers for domestic and foreign markets, due to differences in consumer expectations and use of the product. The objective of this study was to conduct an industry-wide survey to identify commonality among and between U.S. beef processor specifications, as well as to identify differences between products sent to varying countries, and to determine a more accurate value of beef export. Countries that have an Export Verification program require suppliers to be certified with the United States Department of Agriculture and submit information about exported products. The EV information was collected and used to determine the countries that were receiving the highest volume of U.S. product, as well as the meat cuts common in each country. The data was also used to assign prices to individual products to ascertain export value. These documents do not show individual differences between how companies cut beef products. Four countries that represent significant U.S. beef export markets (Japan, Mexico, Hong Kong, and Taiwan) were visited. During these visits, product was visually checked and compared to known Institutional Meat Processor Specification (IMPS). Animal diseases and related food safety issues have become concerns to many people in the last decade and traceability is becoming increasingly important throughout the world as a way to control disease outbreaks before they have devastating effects on a country's livestock industries. The objective of this review was to discuss swine identification and traceability systems outside North America.

▼ Production agriculture is faced with many risks which may be difficult to manage and can result in significant negative economic impacts. For the individual farmer, this can be problematic and potentially poses a challenge to remain viable and profitable when faced with uncertain circumstances. Economic matters evaluated in this dissertation include the topics of animal health and crop production efficiency both focusing on improving production agriculture. This dissertation is comprised of three separate essays or three individual chapters. The first chapter contains an essay on a growing global threat to human health and safety and the biosecurity of livestock production in the United States in the form of antimicrobial resistant pathogens. An equilibrium displacement model (EDM) of the U.S. meat industry (i.e., beef, pork, lamb and poultry) is used to analyze welfare implications occurring from the potential restriction on the use of antimicrobial technologies or the implementation of biosecurity measures at the slaughter (i.e., feedlot) level of beef cattle production. Producer and consumer surplus measures showed that the beef industry losses the most from a reduction on the use of antimicrobial technology in beef cattle production in both the short- and long-run. An 11.95% industry adoption of a wildlife population management (WPM) program on livestock facilities cause a gain in producer surplus of 1.15 billion in the short-run with long-run gains of 18.33 million for the meat industry. The second essay assesses the impact of various biosecurity strategies to prevent the incursion of bovine viral diarrhea virus (BVDV) in a cow-calf herd and minimize the uncertain financial impacts. The specific objectives of this study are to estimate the impact of BVDV introduction to representative U.S. cow-calf operations using an epidemiological disease spread model and to estimate annual costs of BVDV in cow-calf herds. Epidemiological results will be used to evaluate the expected returns and risk for various BVDV biosecurity measures in U.S. cow-calf herds by using a linear programming model which incorporates risk. Results from the study show that, in the context of whole farm planning, vaccination, testing or a combination of both can be effective biosecurity measures to control BVDV. In all five regions, biosecurity strategy M (no biosecurity control measures) generate the highest expected returns which could be a result of no biosecurity costs. Expected returns by each biosecurity strategy shows that N (vaccination of breeding stock) generates the highest expected return for the Southern Plains (SP), North Central (NC), and West (W) regions. Biosecurity strategy T (testing for BVDV) had the highest expected returns for the Northern Plains (NP) and Southeast (SE) regions. The information from this essay is useful to the cow-calf industry as impacts and costs from various biosecurity measures are provided. The third essay estimates and analyzes efficiency measures of conventional and organic crop producers. The…

▼ The stable soybean (and soy product) trade relationship between the U.S. and China is threatened by various market factors. This thesis analyzes the drivers behind soybean trade between the U.S. and China. The economic models are constructed and estimated by Seemingly Unrelated Regressions (SURs) to discover what factors may be influencing U.S. domestic soybean (and soy product) demand, as well as factors influencing U.S. export volumes and China import volumes. Discussion of policy implications will be provided based on the estimation results.

▼ Beef steers (n = 3,906) were fed at a commercial feed yard to evaluate the effects of beta-adrenergic agonist supplementation on live performance, carcass characteristics, carcass fabrication yield and strip loin tenderness and palatability. Steers were weighed and ultrasonic carcass measurements were collected for allocation into four feeding blocks. Within each block, approximately 100 steers were assigned two a pen that was assigned one of five treatments, including: No beta-agonist; Ractopamine hydrochloride (RH) fed at 200 mg/hd/d for the final 30 d of finishing (RAC200); RH fed at 300 mg/hd/d for the final 30 d of finishing (RAC300); RH fed as a 400 mg/hd/d top dress for the final 30 d of finishing (RAC400); and Zilpaterol hydrochloride (ZH) fed at 6.8 g/ton beginning 23 d before slaughter, with a withdrawal period starting 3 d before to slaughter (ZIL). The study design included eight replicates (pens) per treatment (two per block). Each feeding block was harvested on consecutive weeks. Each week, carcass parameters were measured and strip loin samples were collected from 18 carcasses per pen (720 total samples) for Warner-Bratzler and Slice Shear Force, and trained sensory analysis. Subsamples of eight carcasses per pen (320 total samples) were selected for whole carcass fabrication yield. Final BW was not affected by treatment (P = 0.2892), but there was a tendency for cattle receiving βAA supplementation to be heavier compared to controls (P = 0.0681). Average daily gain and F:G ratio was improved with treatment of βAA (P < 0.05). Carcasses from the ZIL and RAC400 treatments had the heaviest HCW, and were significantly heavier than CON and RAC200 treatments (P < 0.05). The ZIL treatment also recorded the highest dressing percent and carcasses had the largest LMA compared to all other treatments (P < 0.05). USDA yield grade and marbling score were reduced due to βAA supplementation (P < 0.05). Differences in marbling score reduced the frequency of carcass qualifying for the CAB premium in βAA treated cattle (P < 0.05), while also accounting for a decrease in the frequency of carcasses grading choice and an increase in the percentage of carcasses grading select for cattle receiving βAA supplementation compared to controls (P < 0.05). The percentage of YG1 carcasses was increased and the frequency of YG3 carcasses was decreased due to βAA treatment (P < 0.05). Treatment with dietary βAA elicited the greatest response in subprimal yield in cuts from the round. Zilpaterol treatment carcasses reported the highest total saleable yield, and were greater than all RAC treatments (P < 0.05). Warner-Bratzler and SSF was affected by treatment (P < 0.05), with an increase in shear force values with increased dose and potency of βAA's. Likewise, the percentage of steaks shearing greater than 4.4 and 20 kg for WBSF and SSF, respectively, was increased with βAA supplementation (P < 0.05). Tenderness attributes were ranked lower for steaks from βAA treatments by trained sensory panelists (P < 0.05). There were no differences…

▼ Colorado State University's Wheat Breeding and Genetics Program is nearing its' 50th anniversary and has had a large role in providing a vehicle of research for increasing wheat yields in
Colorado. During this research process, a database has been compiled of the results of wheat variety experiments held on test plots statewide. The intent of this thesis is to demonstrate additional uses of the data collected by CSU's Wheat Breeding and Genetics Program and the Crop Variety Testing Program. The first essay is an evaluation of the economic impacts that the breeding program has had on wheat yields attributable to the genetic improvement of wheat varieties. Regression analysis is used to estimate and track the genetic improvement that occurs with each newly released wheat variety. The analysis is followed by a monetization of the estimated benefits produced by the program as a result of the increase in wheat yields. Costs of running the program are also discussed. Borrowing from finance literature, the second essay utilizes the
Colorado Wheat Variety Database to generate a portfolio of wheat varieties that would result in minimizing variation while maximizing wheat yields to help producers lower their overall risk levels. Portfolio theory is widely used to select investments in the financial world. The intended application of this study is to aid wheat producers in their selection of wheat varieties.

▼ In Korea, there were five foot-and-mouth disease (FMD) outbreaks between 2000 and 2010. This study examines the impact of the FMD outbreaks on the stock market value of agribusiness firms in Korea using an event study methodology. Eighteen companies in six different groups (i.e., pork, poultry, seafood, imported meat, feed and vaccine) are analyzed. For each outbreak, single-day abnormal returns and multiple-day cumulative abnormal returns are calculated to test for the existence and magnitude of stock price reactions. In addition, changes in volatility after the outbreaks are computed to examine whether the riskiness of returns change due to the events. The results suggest that the FMD outbreaks caused the stock market to react in both a negative and positive manner to related firms. The 2000 outbreaks had the most distinguishing and consenting results to prior expectations. The 2002 results showed relatively stable changes of returns due to appropriate governmental programs. In the 2010 events, some companies' stock market reactions were unexpected and did not meet our prior expectations as a result of other factors such as market supply and demand conditions and another animal disease. The results also suggest that the stock market reactions were more gradual than instantaneous to the FMD outbreaks. This study observed more meaningful values of multi-day cumulative abnormal returns than single-day abnormal returns and understands that these long-lasting impacts are due to the continuous negative news reaching the stock market as there were multiple confirmed cases in all outbreaks. When an outbreak severely impacted a particular business sector, the accumulations of abnormal returns became substantial. Many companies had significant results that met prior expectations, but some groups did not maintain consistency in their reactions to the events. The pork companies realized a negative reaction in the 2000 and the third 2010 events when the outbreak presented a negative outlook for the swine and pork businesses. The poultry and seafood firms reacted positively when there were no other substantial market threats. The imported meat group showed mixed reactions while the vaccine companies had consistent positive reactions that met prior expectations. The feed companies reacted negatively when the outbreaks substantially damaged the livestock production sites. Volatility of the stock prices after the FMD events increased, with more companies showing significant results in a longer-lasting outbreak. The results imply that managers and shareholders of the affected firms should pay more attention on management of their assets when there is an FMD and other animal disease outbreaks. It also implies that appropriate governmental interventions help mitigate damages on the stock market.

▼ Feral swine are known to cause damage to crops among other types of property damage. With a lack of economic welfare estimates of feral swine crop damages, the first essay of this dissertation addresses this gap in the literature by estimating the value of feral swine removal with respect to five crops in nine southern states. An equilibrium displacement model was used to assess the changes in price and quantity that would result from eliminating damage to corn, soybeans, wheat, rice, and peanuts in these nine states. Changes in price and quantity are then used to calculate the changes in producer and consumer welfare in both the short and long-run. Respectively, those net surplus gains are 142 million and 89 million. The second essay addresses the need for analysis in complex management questions. The essay serves as an advance in building an agent-based model for use in feral swine management and extending it by developing a method for passing optimal management information to the agent-based decision maker. This essay constructs an agent-based model for use in examining different imperfect, but reasonable, ways that decision makers could implement a marginal benefit to the removal of feral swine and a marginal cost of removal. This essay finds that the implementation of the marginal benefit to removal matters for the land managers. Further, the essay finds that the dynamics of the sounder and movements related to sounders matter to the land managers and society at large and encourages further research into that area.

▼ For consumer satisfaction to occur, beef retailers and producers must continuously provide beef that contributes to desirable beef flavor. The objectives of this research was: 1) determine the consist of preference for beef flavors resulting from various production practices among beef consumers, 2) develop a true ranking of preference via best-worst (B/W) scaling, and 3) identify the proportion of preference for beef product categories resulting from various production practices. Nine consumer panels were conducted in three different geographical locations (eastern, central and western US). Consumer beef flavor preference was determined using B/W scaling, multinomial logit, and random parameter logit models in SAS® MDC. Proximate analysis and consumer ranking of attributes when making beef purchases was analyzed using an ANOVA, then means were separated using least squares means in SAS® and consumer demographic information was analyzed using PROC GLIMMIX. Overall, the four samples with the greatest percentage of lipid, F-1 Wagyu x Angus (20.2%), wet-aged upper two-thirds USDA Choice (15.6%), USDA Prime (14.7%), and dry-aged upper two-thirds USDA Choice (13.7%) resulted in a greater percentage of preference for flavor than product categories with a lower percent lipid, low USDA Choice (12.5%), USDA Select (11.9%), beef derived from domestic grass-fed cattle (6.8%); and beef derived from Uruguayan grass-fed cattle (4.5%). Results suggest the incorporation of Wagyu genetics, breeding cattle for a greater propensity of lipid, and grain finishing market beef cattle should result in a more preferred beef flavor characteristic. Results from demographic preference show females, Millennials (18 - 34 years of age), and respondents with an average or higher household income are more likely to consider beef derived from Uruguayan grass-fed cattle as their least preferred sample. Results from consumers making beef purchasing decisions show marbling level (3.8) and USDA grade of product (4.2) are moderately important and if the product was grass-fed vs. grain-fed (7.5) is the least important beef characteristic. Demographic information shows Baby Boomers (over 50 years of age) prefer beef derived from domestic grass-fed cattle (10.3%) more than both Generation X (6.0%; 35 - 50 years of age) and Millennials (7.1%; P < 0.05). Baby Boomers (18.6%) also prefer dry-aged upper two-thirds USDA Choice more than Millennials (13.6%; P < 0.05).

▼ In order to mimic beef commonly found in retail supermarkets, paired strip loins (NAMP180) and top sirloin butts (NAMP #184) were obtained from USDA Choice carcasses with a marbling score ranging from Small00 to Small50 (n = 15) and USDA Select carcasses with a marbling score ranging from Slight50 to Slight99 (n = 15) at a commercial packing plant. Samples were collected from 3 separate groups of carcasses in order to replicate each aging and display period three times. At 48 hours postmortem, paired strip loins and top sirloin butts were portioned into 3-inch sections, vacuum-sealed, and stored 14, 21, 28, 35, 49, or 63 days postmortem. For both strip loin and sirloin sections, once the aging period was designated, the sections were stored in a vacuum-sealed bag at 0°C (± 1°C) and in the dark until their assigned aging period was complete. Two steaks from each aged section for each muscle was placed in a styrofoam tray with a polyvinyl chloride overwrap and placed in a multi-deck retail display case equipped with LED lighting (Hussmann Model No. M3X8GEP) and set at 2°C for 72 hrs. A third steak cut from each aged section was immediately cooked, and Warner-Bratzler shear force (WBSF) analysis was measured to determine the effects of the aging period on tenderness without the display period. During the display period, each steak was evaluated every 8 hours by a minimum of 8 trained panelists for lean color, external fat color, lean percent discoloration, and L* a* b* color values. A trained sensory panel for tenderness and flavor attributes, including off-flavors, also was used to evaluate steaks. As steaks were subjected to longer periods of postmortem aging, WBSF values decreased and trained sensory panel tenderness ratings improved. A 72 h display time reduced (P < 0.05) WBSF values of strip loin and sirloin steaks. A minimum of 28 d of postmortem aging was required to improve the WBSF values of low Choice and Select strip loin steaks compared with the same strip loins steaks aged for 14 d, and a minimum of 35 d of postmortem aging was required to improve sensory tenderness ratings for low Choice and Select strip loin steaks. Strip loin steaks aged up to 28 d before retail display had little impact on display life and the incidence of off-flavors; however, there was no tenderness advantage over 14 d aged steaks from low Choice and Select strip loins. Thirty-five days of postmortem aging were required to achieve an improvement in WBSF compared to that achieved with 14 d aging for low Choice and Select top sirloin steaks, and trained sensory panel scores indicated that at least 49 d of postmortem aging was required to improve the myofibrillar tenderness of low Choice and Select sirloin steaks. Sirloin steaks aged 35 d and beyond produced undesirable lean color scores in as early as the first 24 h of retail display, and top sirloin steaks aged only 14 d and displayed an additional 72 h had relatively intense levels of oxidized and sour/acidic flavors present. Top sirloins cannot be aged for enough time to improve…

▼ Repeated experiences of volatility with Class III milk prices have caused many producers, wholesalers, and retailers to avoid risk management decisions involving the Class III milk price; instead market participants realize profits as they occur without managing their financial environment based on their expectations. This research forecasted Class III milk price from August 2012 to July 2014 using data from January 2000 to July 2012. The conclusions of this study found that the unrestricted vector autoregressive model is the best forecast both for ex-post and out-of-sample methods. Additionally, it was determined that the futures prices are not strong reflections of feed costs, although one to four months prior to expiration the futures contract price reflects the current feed costs to some degree. Also six to eight months prior to contract expiration there is little movement in the contract price, and the previous month's price has a large influence on the current month's price during this time. It can be concluded that the futures contract price is largely driven by current market conditions during the remainder of the time prior to contract expiration.

▼ This study quantified relationships of recently adopted camera-based USDA beef quality grades to LM sensory attributes and shear force. Heifer and steer carcasses (n = 718, all A-maturity) were selected at beef processing plants in CO, KS, NE, and TX, using marbling scores determined by on-line camera grading systems, to represent 7 marbling degrees: Traces (TR), Slight (SL), Small (SM), Modest (MT), Moderate (MD), Slightly Abundant (SA), and Moderately Abundant (MA). Strip loin steaks were obtained from both sides of each carcass and aged for 14 d. One steak was used to obtain Warner-Bratzler shear force (WBSF) and slice shear force (SSF) measurements; the other steak was evaluated by a trained sensory panel for juiciness, tenderness, detectable levels of several flavors (meaty/brothy, buttery/beef fat, bloody/serumy, livery/organy, and grassy), and overall sensory experience (negative vs. positive). Camera marbling score explained 45, 40, 32, 71, and 61% of the variation in panel ratings for juiciness, tenderness, meaty/brothy flavor intensity, buttery/beef fat flavor intensity, and overall sensory experience, respectively. Increased degree of marbling resulted in steaks having greater (P < 0.001) juiciness, tenderness, meaty/brothy flavor intensity, and buttery/beef fat flavor intensity. The likelihood of a steak delivering a positive sensory experience also became greater (P < 0.001) as degree of marbling increased (MA = SA > MD = MT > SM > SL > TR). Nearly all (98 to 99%) of the steaks with MA and SA marbling, and most (between 80 and 90%) of the steaks with MD and MT marbling received positive ratings for overall sensory experience compared with 62% of the SM steaks, 29% of the SL steaks and 15% of the TR steaks. Steaks produced by steers had lower (P < 0.05) WBSF and SSF values and were generally rated as more tender by sensory panelists than steaks produced by heifers, but the effect of sex on panel tenderness was significant only within the TR category. Comparison of 2 methods for determining camera-based quality grades (i.e., use of original camera grade lines, based on marbling assessments of USDA grading experts vs. use of adopted camera grade lines, based on marbling assessments of field graders) showed that both methods of grade placement effectively stratified carcasses into grades that differed (P < 0.05) with respect to steak juiciness, tenderness, and flavor, with little discernible difference between methods.

▼ There is a growing public interest, and consequently, support for public policies and programs to support local food systems. These programs aim to inform consumers about the potential benefits of local foods and influence consumers' choice among differentiable foods. As
state promotion and marketing programs have been widely adopted throughout the country, demand for local produce and market opportunities for locally-branded products have increased significantly. Local promotion programs have also started to influence the structure of markets, as demand has stimulated a proliferation of localized, direct marketing supply chains linking growers directly to consumers. However, there are few true examinations focused on the welfare implications surrounding the restructuring of food markets and or the underlying economic performance of market innovations. The main objective of this study is to explore the structural and performance dynamics of a market as a result of new labeling efforts and promotional campaigns, highlighting the availability of locally grown products (both in direct markets and within more conventional marketing channels). This study develops a partial equilibrium displacement model for
Colorado apples to analyze the impacts of local labeling. The information obtained from the result of this model informs how consumer perceptions and marketing channel structure influence market performance. To complement the broader analysis, the market structure and price relationship at different market levels are examined. The results showed that the Southwest and Northeast retail markets dominated national retail markets and the Northwest retail market dominated western retail markets in terms of its influence on retail prices. Not surprisingly the Yakima Valley and Wenatchee District in Washington significantly affected the price formation process of all other shipping points. If the unknown transaction cost band is allowed to vary according to transportation costs and seasonality, it may more closely mimic suppliers who view more opportunities to adjust their supply between regional markets in search of potential profits. Overall, local labeling increases consumers' willingness to pay for local apples relative to domestic apples in
Colorado, and subsequently, demand will shift toward local apples and the supply will shift toward direct markets in
Colorado. In terms of producer surplus,
Colorado suppliers for direct markets gain while
Colorado suppliers for shipping points lose in short run. In the long run, both suppliers will gain but the suppliers for direct markets will gain more than the suppliers for shipping points. Overall, the
Colorado producers lose in the short run while they gain in the long run.

▼ Animal agriculture in today's economic environment is often complex and the uncertainties involved in the decision process make being profitable a challenge. Serving as business consultants, veterinarians can aid producers in helping to make profitable decisions by utilizing available decision tools that enable a better understanding of the economic risk for decisions. Scientific studies that examine the biological response to health or management interventions on dairy farms, while valuable for understanding biology are sometimes limited in their ability to aid in the making good decisions for interventions in agriculture. Adding economics as well as incorporating the variance associated with point effect estimates of biological effect may be a way to decrease the uncertainty or better understand the risk surrounding a management decision. One decision tool available for understanding possible interventions is the use of cross sectional surveys and longitudinal observational studies. A longitudinal study was designed to evaluate various management factors and feed additives and their association with undifferentiated diarrhea events on dairy farms. Based on data from 76 farms, our research team found that a fermented Saccharomyces cerevisiae yeast culture (SCFP) reduced the risk of a cow having a diarrhea event by 30% (IR = 0.707 (P = 0.043, CI = 0.505, 0.989). In addition, having a herd located in the Eastern US versus the Western US was associated with more diarrhea events (IR= 2.036 P = 0.066, CI = 0.953, 4.39). In striving to find the best literature and studies available to help guide the decision process, published studies may differ in estimates of the magnitude of herd response to various management inputs (actions). One key tool that is gaining scientific prominence is the use of meta-analytic techniques to combine multiple studies into a single entity to predict the effect of certain interventions on certain indices of herd health and productivity. A meta-analysis of thirty-six separate studies on a Saccharomyces cerevisiae yeast culture fermentation product was conducted. A total of 69 comparisons met the criteria for inclusion in a random-effects meta-analysis and a sub-group analysis of peer reviewed studies of feeding a SCFP showed an estimated raw mean difference between treated and untreated cattle of 1.18 kg/d (95% CI, 0.55 to 1.81), 1.61 kg/d (95% CI, 0.92 to 2.29), and 1.65 kg/d (95% CI, 0.97 to 2.34) for milk yield, 3.5% fat corrected milk and energy corrected milk, respectively. Milk fat yield and milk protein yield showed an increase in the raw mean difference of 0.06 kg/d (95% CI, 0.01 to 0.10) and 0.03 kg/d (95% CI, 0.00 to 0.05). Estimated raw mean difference in dry matter intake during early lactation (< 70 DIM) and non-early lactation were 0.62 kg/d (95% CI, 0.21 to 1.02) and a decrease of 0.78 kg/d (95% CI, -1.36 to -0.21), respectively from feeding SCFP. Another meta-analysis of active dry yeast (ADY) products was performed; this included 22 papers with 25 comparisons that met the final…

▼ Quality is an accumulation of attributes that satisfy customer preferences and expectations. Lamb quality is a moving target that means different things to the supply chain and sheep/lamb industry stakeholders. The objectives of this research were to determine the rank, definition, relative preference, and willingness to pay (WTP) for seven quality attributes and quantify product attributes of lamb at U.S. retail markets. Structured interviews of retail and foodservice respondents were conducted from May 2014 to March 2015 via face-to-face or telephone with lamb/protein purchaser representatives of retail (n = 60), foodservice (n = 45), and purveyor (n = 15) marketing sectors. Shares of preference (relative percentage of preference) in best/worst evaluation for all interviews indicated that eating satisfaction (38.9%) was the most important attribute. Shares of preference for all seven specified quality attributes were statistically different from each other (P < 0.05). Credence attributes of origin (17.2%) and sheep raising practices (13.6%) ranked second and third overall, respectively. Physical product characteristic traits of product appearance/composition (10.5%) and weight/size (8.5%) were ranked fourth and fifth in shares of preference, respectively. Nutrition/wholesomeness (7.1%) ranked sixth and product convenience/form (4.2%) ranked seventh in the overall ranking across all sectors of retailer, foodservice, and purveyor interview respondents. In WTP analyses, origin (25.8%) and sheep raising practices (20.0%) had the greatest likelihood of being a non-negotiable requirement for lamb purchasers. Eating satisfaction was the trait most likely to receive a premium (71.7%) from buyers, and product assurance of eating satisfaction generated the greatest average WTP premium (18.6%). This research indicated, across all sectors, eating satisfaction, defined as lamb flavor/taste, was the most important quality trait to those who purchase lamb. In-store evaluations of retail lamb labels showed that lamb shoulder and loin chops originating from the U.S. garnered the greatest price premiums compared to either New Zealand or Australian lamb (P < 0.05). Lamb was merchandised to American consumers at specialty type stores at an increased price per kg premium than either locally owned or national grocery chains (P < 0.05). Lamb shoulder prices at retail were merchandised with the greatest premium for product of U.S. origin from a specialty store packaged in modified atmosphere packaging and labeled with local (+ 5.42/kg) and natural (+ 5.40/kg) claims (P < 0.05). Lamb loin prices at retail were merchandised with the greatest premium for product of U.S. origin from a specialty store merchandised in a full service case or modified atmosphere packaged and labeled with a source verified and branded (+ 7.21/kg) label claim (P < 0.05). Shoulder and loin chop prices analyzed via hedonic modeling were not different for store location (East, Central, and West) nor USDA process verified Never-Ever 3 claim (P >…

▼ This thesis uses a landscape approach incorporating landesque capital as statecraft to relate agricultural intensification and
state formation theories using data collected from the former island of Apúpato, in the Lake Pátzcuaro Basin, Michoacán, México. Apúpato is located in the geo-political core of the Purépecha Empire, south of Tzintzuntzan, the empire's capital. Apúpato was an important Purépecha island belonging to the Canzonci [Purépecha emperor] and was used as a ritual center, an imperial treasury, and for feasts and expeditions (RM 2008: page) This thesis incorporates recent archaeological investigation, including full coverage settlement pattern survey, geoarchaeology, and remote sensing/ARCGIS, which documented patterns of settlements, confirmed the presence of terraces, and the general landscape development of the former island. This thesis documents and analyzes, for the first time, agricultural terraces in the former island of Apúpato. The most common form of agricultural intensification is terrace agriculture (Donkin 1979) which is linked to the development of social complexity in middle range societies, and states and empires (Fisher et al. 2003). For Mesoamerica, terraces are a fundamental characteristic of ancient social complexity, and continued to be used post-Conquest (A.D. 1520). In the Lake Pátzcuaro basin, agricultural intensification was an important component of
state formation in the lake Pátzcuaro basin (Pollard 1993) exemplified by raised field systems and by the construction of terraces to repair Classic period land degradation (A.D 300-800) and to improve productivity of seed crops (Fisher et al 2003; Fisher 2005). This thesis examines the implications of agricultural intensification and
state formation in Mesoamerica, using terrace data collected from the former island of Apúpato. The terrace system documented on Apúpato represents a refugia for the Purépecha built environment in the Lake Pátzcuaro Basin, since the Apúpato island setting remained an island for hundreds of years, helping keep Apúpato protected and isolated from the consequences of the European conquest. The terraces documented in the former island of Apúpato are analyzed in terms of their form, function, and construction development for the first time in the Lake Pátzcuaro Basin.

▼ In the United States, concern has arisen regarding the potential introduction of foot-and-mouth disease (FMD), a foreign animal disease, and its subsequent spread by feral swine populations into domestic livestock. Feral swine are ideal candidates to potentially spread FMD, because they are free ranging with sizeable home ranges, frequently contact domestic livestock, have high fecundity and populations are expanding geographically throughout the United States. Feral swine surveillance is becoming a solution to safeguard and mitigate the potential for feral swine to transmit FMD to domestic livestock (e.g., cattle, pigs, and sheep). The potentially devastating economic impacts were evidenced by the economic impact of FMD in the UK and Taiwan (FAO, 2009; Yang et al., 1999). It has been estimated that if FMD were to enter the U.S. the economic losses would be $14 billion (Paarlberg et al., 2002). Such large potential losses are an example of the important economic contribution that livestock production makes to the larger U.S. economy. The objective of this research is to analyze the farm level impacts of alternate surveillance systems in feral swine in the event of a FMD outbreak in Kansas. Specifically, a disease spread model is used to model and evaluate the spread of FMD in Kansas. Output from the disease spread model is incorporated into a partial equilibrium model to determine the changes in prices. The change in prices for grains and livestock are then used to evaluate the farm level impacts in Kansas using whole farm budgets. Results obtained from the disease spread model indicate that under no surveillance the largest amount of animals are destroyed, 2,599,419, with a duration of 193 days. Under twice per month surveillance, 2,555,768 animals are destroyed and the outbreak lasts 189 days. Once per week surveillance shows that 2,585,666 animals are destroyed and the duration lasts 192 days. The NAADSM results for Kansas show that the states livestock industry could potentially face large livestock losses from feral swine transmitting FMD. The impacts to the average farms in Kansas show that producers with a large amount of livestock, in particular swine, see the biggest percentage changes in net income levels. This would be expected as pig and hog prices decrease once the FMD outbreak occurs and return to base levels in quarter four showing that there is a loss in swine prices from a FMD outbreak. Cattle prices initially decrease once the FMD outbreak occurs but then increase above base levels showing that average farms have the potential to regain lost revenues. The whole farm income results indicate that a producer not in the quarantine zone has the potential to capitalize on increasing livestock prices once the trade restrictions are lifted after quarter three.

▼ The majority of mating systems in the U.S. beef industry have focused on increasing revenue by applying selection pressure to economically relevant traits (ERT) for outputs such as growth, calving ease, and carcass quality. There are other ERTs that affect profitability that can be improved through selection like feed intake, heifer pregnancy, and longevity. The purpose of this thesis was to expand the effective use of residual feed intake (RFI) in two distinct manners. Therefore, the objectives of the first study were to compile published estimates of heritability and genetic correlations of feed conversion ratio (FCR), RFI, average daily gain (ADG), metabolic body weight (MBW) and dry matter intake (DMI). These estimates were used to calculate weighted estimates of the respective genetic parameters. Twenty-five sets of estimates involving more than 40,000 cattle published between 1961 and 2010 were included in a meta-analysis of genetic parameters for feed intake and related traits. A generalized least squares approach was used to compute weighted mean heritability and genetic correlation estimates, as well as their SE, where weights were a function of inverse SE. Weighted heritability estimates for FCR, RFI, ADG, MBW and DMI were 0.28±0.06, 0.38±0.08, 0.32±0.08, 0.39±0.08, and 0.38±0.06, respectively. Weighted genetic correlations of FCR with RFI, ADG, MBW, and DMI were 0.60±0.07, -0.31±0.14, 0.03±0.14, and 0.35±0.11, respectively. Weighted genetic correlations of RFI with ADG, MBW were near zero, but were correlated 0.38±0.11 with DMI. The weighted genetic correlation of ADG with MBW was 0.45±0.13. These weighted heritability and genetic correlation estimates may be more useful in the design of genetic improvement programs than relying on estimates from individual studies with low numbers of feed intake observations. For the second study, daily feed intakes were recorded on 3,702 bulls and 314 heifers across nine tests between 2007 and 2010 at Midland Bull Test in Columbus, Montana. Daily feed intake was recorded and from this DMI was calculated. Genetic variances were estimated using a multiple trait animal model and average information REML. The model was equivalent for DMI, ADG, MBW and RFI which included a fixed effect of contemporary group (breed x test x pen, n=112) and a linear covariate for age at start of test (=298.28d, SD=36.65). The heritability estimate for RFIp was 0.17 ± 0.05. Genetic correlations among growth traits (ADG, MBW and DMI) were moderate to high and positive, ranging from 0.33 to 0.70. The model including DMI and RFIp failed to converge. This resulted in the need for estimation of genetic residual feed intake (RFIg), defined as the difference between DMI EBV and expected DMI EBV. Genetic regression was used to predict expected DMI EBV from the EBVs of ADG and MBW. This approach to the genetic evaluation of RFIg allows for the estimation of breeding values that may truly reflect feed utilization differences among animals without simultaneously affecting growth or body size.

▼ Globalization has expanded market opportunities for U.S. livestock producers. With the increase in world travel and globalization of agriculture, the possibility of transmitting a highly contagious foreign animal disease to the U.S. is higher. Therefore, it is critically important to develop and assess economic implications of emergency management plans in the event a contagious livestock disease outbreak was to occur in the U.S. For example, the United Kingdom experienced a severe FMD outbreak in 2001. By the end of the outbreak, 221 days after it started, 2,026 cases of FMD had been confirmed, over six million animals were destroyed, and the disease had spread to Ireland, France, and the Netherlands. Thompson et al. (2002) estimated losses from FMD in the UK at £5.8 to £6.3 billion (8.47 to 9.20 billion U.S.). Responding to public opposition in the UK to the eradication measures, as well as the demand for an alternative destruction approach because of limited carcass disposal due to concerns about water (burial) or air pollution by smoke (burning), the USDA's Animal and Plant Health Inspection Service (APHIS) - Veterinary Service (VS) recently unveiled its vision for the future called VS 2015. According to APHIS (2009), VS 2015 "will allow the organization to place greater emphasis on disease prevention, preparedness, detection and early response activities" (page 1). There are several forces driving this initiative and its focus: diseases that were once eradicated or controlled are beginning to emerge again, changes in the industry structure (an increase in the number of large-scale, production-intensive operations), advances in technology, public awareness of diseases, demand for protein (especially in developing countries), and shrinking federal budgets (which has an increased emphasis on optimal allocation of resources). Combining APHIS's VS 2015 vision and the recent advances in FMD vaccines, it is imperative that policies are developed with input from both the epidemiological and economic sciences. The purpose of this study is to estimate the epidemiological and economic impacts associated with the various emergency vaccination strategies in the event of a FMD outbreak in a large cattle feeding region, where large-scale depopulation activities might not be feasible. In this study, we will compare the impacts of using vaccination as a way to control the spread of FMD on the time of detection and across herd size. Additionally, we investigate the changes in producer and consumer welfare associated with: the optimal timeframe in which officials have to begin the vaccination strategy; and destruction or alternative marketing channels for vaccinated animals (i.e., what happens if all vaccinated animals are destroyed vs. if the vaccinated animals are not destroyed.) To achieve the objectives of this study, a stochastic epidemiological disease spread model is used to simulate a hypothetical FMD outbreak outside of this thesis. Results from the disease spread model are then incorporated into an equilibrium…
