From the time of Don Hernando Cortez, livestock has been one of America's greatest industries. The cattle in Cortez ' s time were Moorish stock which had been bred for centuries in the Andalusian Plains of Spain.

Incidents affecting the livestock industry are unavoidable in today's society. These incidents can happen at livestock shows across the country putting thousands of exhibitors, visitors, employees and livestock in danger. The purpose of this study was to determine local officials' perceptions and awareness of incident planning and response pertaining to selected livestock shows. Little research has been completed in this area; therefore, this foundational study was needed. The objectives of this study were to determine local officials' awareness of livestock shows and incident response plans for those livestock shows. In addition, the researcher wanted to describe the roles of local officials in incident planning and response at livestock shows. Level of communication and perceptions of challenges at livestock shows and among local officials were also evaluated. Lastly, the researcher wanted to describe local officials' recommendations for effective incident planning and response related to livestock shows. Five participants remarked on the value of this study and agreed to participate. These participants included livestock show officials involved in incident planning and response or local emergency management officials. Each participant was interviewed, and then data were transcribed and categorized to consensus. Nine themes arose including: background information, challenges, communication, example incidents, executing incident response, incident response planning, incident response training, miscellaneous and need for planning. It was concluded that all participants were aware of the selected livestock shows. However, levels of awareness varied by participant due to work-related experiences with the livestock show. The two livestock show participants were aware of specific incident response plans for the livestock show, while the three local emergency management officials were aware of city emergency management plans. Each participant remarked upon their roles in planning and executing incident response. In addition, communication was thought to be one of the key factors to successful incident planning and response. Challenges ranging from lack of communication to training for incident response were stated. Lastly, participants remarked on recommendations for others planning for incident response at livestock shows. These recommendations included communication, preplanning, building relationship with key stakeholders, training, and a need for more planning and research in this area. It is recommended that this study be replicated with scaled objectives for measuring awareness of livestock shows and incident response plans. Also, replicate this study to determine level of training in incident response and safe handling of livestock. It is recommended to describe communication between livestock shows and local emergency management officials. Lastly, it is recommended to replicate this study with regional livestock shows and state fairs.

Experimental results indicated that dolomite dissolution rates increased in all the acid solutions as the disk rotational speeds increased at 150, 200, and 250˚F. The dissolution of dolomite in 0.886 M GLDA was found to be surface-reaction limited at lower temperatures and mass-transfer limited at highest temperature. GLDA with the lowest reaction rates and relative diffusion coefficient demonstrated retardation before spending with deeper penetration capability for productivity and injectivity improvement. The purpose of this study was to analyze the Texas Quality Counts Verification Exam for junior and senior aged 4-H and FFA members. The Texas Quality Counts program was developed due to a need for teaching livestock ethics and care to the youth of Texas and it strives to teach youth how to produce a safe and wholesome livestock product for the consumer. An analysis of youth scores between 2011 and 2012 was done to determine how well youth were scoring on the Texas Quality Counts Verification Exam. Out of the 91,733 attempts, 18,204 were taken by juniors and 73,572 were taken by seniors. Junior level attempts show a fairly even spread among self-identified membership in 4-H and FFA, while senior level attempts saw a much greater spread in membership, with 73% of attempts taken by youth who identified themselves as a member in FFA. Overall, 78% of junior level youth were able to pass the exam on their first attempt, and showed a range of mean attempts between 1.13 and 1.47 based on age. Senior level youth, on the other hand, had only 47% pass on their first attempt and had a range of mean attempts between 2.21 and 2.54 based on age. The means of scores on the exam were calculated for juniors and seniors, with 0.85 and 0.71 respectively. To determine if there were any differences in scores between self-identified membership in 4-H, FFA, or both 4-H and FFA, a oneway ANOVA for junior and senior members was conducted. Both junior and senior age groups showed a significant difference between the three membership categories (p=0.001).

Livestock and companion animals are valuable economically and emotionally in the economy of many states and to their citizens. In a radiological emergency situation, the loss of a large amount of livestock could be devastating to a state or national economy. If such an event occurred, there are currently no screening and decontamination protocols for the handling of livestock. This research investigated current policies and procedures for monitoring and decontamination of livestock and companion animals, as well as testing pedestrian portal monitors and a newly designed livestock portal capable of radionuclide identification. It was discovered that only ten states addressed companion animals or livestock anywhere in their emergency planning. Of the ten, only North Carolina, Washington, and a Massachusetts K9 unit had detailed decontamination procedures to report for companion animals. None of the states included detailed procedures for livestock. To address livestock screening, three pedestrian portal monitoring systems were tested in the field and lab trials – the Johnson AM801, TSA TPM903A, and Ludlum 52-1-1. The systems were tested for position and count rate sensitivity with 1 and 5 µCi 137Cs sources placed on four locations on a steer. Factors such as operability and ease of use were also considered. All three systems would alarm when a 5 µCi 137Cs source was used and the occupancy sensor was triggered. The Johnson AM801 system was determined to be the most appropriate for use in livestock screening due to sensitive alarm algorithms, greater position discrimination with four detectors, and ease of adjustment for agricultural purposes. The last phase of this project included designing and constructing a portal system that included radionuclide identification capabilities. An array of six sodium iodide detectors was mounted on a panel and field-tested beside a cattle chute and in a walkway. The custom portal, the Bovine Screening Portal (BSP), observed increased count rates (>10σ) from a 5 µCi 137Cs source in live time. The BSP demonstrated better detection and localization of the source and spectral identification capabilities compared to the commercially available pedestrian systems.
