Seasonal Prevalence Of Shiga-Toxin Producing Escherichia Coli On Beef Cattle Farms In Eastern Arkansas, Tiffani Elizabeth Breckenridge

Student Theses and Dissertations

Sixty-five million U.S. citizens become ill from foodborne bacteria annually; 73,000 of these bacterial illnesses are caused by Shiga-toxin producing Escherichia coli (STEC) O157. Cattle are a reservoir of STEC; therefore, STEC contamination of beef is a significant food safety concern in the U.S. On-farm STEC control measures may reduce the incidence of contamination in processing facilities. The objective of this study was to determine prevalence of O157 and non-O157 STEC on beef cattle farms in eastern Arkansas, and to possibly identify farm management and/or environmental risk factors associated with STEC prevalence in cattle. Rectal swab samples (10 cows per …

Productivity Of Pre-Modern Agriculture In The Cucuteni-Trylillia Area, Anvar Shukurov, Mykhailo Videiko, Graeme Sarson, Kate Henderson, Robert Shiel, Pavel Dolukhanov, Galina Pashkevich

Human Biology Open Access Pre-Prints

We present palaeoeconomy reconstructions for pre-modern agriculture; we select, wherever required, features and parameter values specific for the Cucuteni–Trypillia Cultural unity (CTU: 5,400–2,700 BC, mostly the territory of modern Ukraine, Moldova and Romania). We verify theself-consistency and viability of the archaeological evidence related to all major elements of the agricultural production cycle within the constraints provided by environmental and technological considerations. The starting point of our analysis is the palaeodiet structure suggested by archaeological data, stable isotope analyses of human remains, and palynology studies in the CTU area. We allow for the archeologically attested contributions of domesticated and wild animal …

Managing Precision Dairy Farming Technologies, Barbara Alice Wadsworth, Amanda Stone, Lauren M. Mayo, Nicky Tsai, Jeffrey M. Bewley

Agriculture and Natural Resources Publications

Precision dairy farming is the use of technologies to measure physiological, behavioral, and production indicators of individual animals to improve management strategies and farm performance. These systems have the potential to detect disease and estrus and to evaluate cow comfort by monitoring activity, feeding time, lying time, mounting activity, real-time location, reticulorumen pH, rumination time, and body temperature.

The data provided by a precision dairy farming device is only valuable if it records the data properly for the right cow and is used by the producer. This factsheet will describe problems that researchers at the University of Kentucky have experienced …

Florida's Downtowns Are Free To Grow Local Broccoli…And Chickens (Sometimes), Sidney F. Ansbacher, Michael T. Olexa, Kathleen Maurer

Florida A & M University Law Review

The United States Supreme Court in National Federation of Independent Business v. Sebelius (Sebelius), famously invoked broccoli to limit the scope of Commerce Clause. All of the Justices used broccoli as a plot device to further their respective arguments answering whether the individual mandate to buy health insurance was constitutional. This article discusses the other end of the economic spectrum – local. We explicate Florida’s local government regulations of urban planting, growing, and selling of broccoli, as well as other fruits, vegetables, and animals. This requires a history of urban agriculture and local zoning laws before we discuss current laws …

Application Of New Type Of Antiseptic Natamycin In Liquid Feed, Lei Dezhu, Huang Yongjian

Food and Machinery

Inhibition effects were investigated for new type of antiseptic natamycin and the combination of natamycin and sodium diacetate on common mildews, including Aspergillus niger, Rhizopus niveus, Mucor corticolus, Penicillium glaucum. The results indicated that the minimal inhibition concentration of natamycin was 3～6 mg/L, while the optimized inhibition ratio was 4 mg/L to 3 g/L in the combination. Destructive storage test was also conducted at 10, 20 and 30 mg/L respectively in this paper, and little difference were observed according to the result by plate counting. 100% inhibition effect of natamycin at 10 mg/L could be expected to last for 18 …

The Agricultural Footprints On The Environment, Philip Houtz

Kaleidoscope

Industrialized agricultural systems have given America a convenient and affordable means to supply a surplus of food products to its citizens. Transgenic technology, synthesized fertilizers, advanced pesticides, concentrated animal feeding operations (CAFOs), and the use of farm machinery have all contributed to humanity’s ability to feed the world’s rapidly growing population. However, the energy-intensive food operation of today may not be as ideal as we assume. Fossil fuels are burned to meet the energy requirements for the continual production of large quantities of fertilizer and to keep farm machines operational. Fertilizer and pesticide runoff from farmland ultimately drains into rivers …

Detecting Genomic Regions Responsible For Resistance In Arabidopsis, Valeria Cancino, Anjali Iyer-Pascuzzi, Rucha Karve

The Summer Undergraduate Research Fellowship (SURF) Symposium

Ralstonia solanacearum is a soil-borne plant root colonizing pathogen and the casual agent of bacterial wilt (BW) disease. BW leads to severe yield loss in a wide variety of agricultural commodity crops, such as tomato, banana, and pepper. In this study, we look at the plant-pathogen interaction between Ralstonia solanacearum and various ecotypes of Arabidopsis thaliana with the goal of finding resistant ecotypes. To identify resistant ecotypes, seeds are first sterilized and left to soak in the dark. Then the seeds are plated on agar media, transferred to a growth chamber, and allowed to grow for 5 days. On day …

Evaluation Of Two Non-Destructive Methods For Estimating Biomass In A Prairie, Arnoldas Pivorius, Laura Ploughe, Jeff Dukes

The Summer Undergraduate Research Fellowship (SURF) Symposium

The estimation of above ground biomass is important in managing natural resources, like assessing habitat conditions. Direct, destructive measurements by clipping, drying, and weighing plant matter is time consuming and labor intensive. It is of interest to develop non-invasive methods to complement or replace direct vegetation harvest. Two non-invasive methods were evaluated, light penetration and visual obstruction, in the Purdue Wildlife Area prairie. Light penetration in the grassland plots were measured using a Decagon light stick (LP-80), 5 cm from the ground and above the plants. Estimation of visual obstruction was done using a Robel pole, which focuses on the …

Occurrence Of An Herbicide-Resistant Plant Trait In Agricultural Field Margins, Karla L. Gag, David J. Gibson, Bryan G. Young, Julie M. Young, Joseph L. Matthews, Stephen C. Weller, Robert G. Wilson

Department of Agronomy and Horticulture: Faculty Publications

Agricultural environments allow study of evolutionary change in plants. An example of evolution within agroecological systems is the selection for resistance to the herbicide glyphosate within the weed, Conyza canadensis. Changes in survivorship and reproduction associated with the development of glyphosate resistance (GR) may impact fitness and influence the frequency of occurrence of the GR trait. We hypothesized that site characteristics and history would affect the occurrence of GR C. canadensis in field margins. We surveyed GR occurrence in field margins and asked whether there were correlations between GR occurrence and location, crop rotation, GR crop trait rotation, crop type, …

All-Weather Surfaces For Cattle Watering Facilities, Stephen F. Higgins, Kylie Schmidt, Donald J. Stamper, Kevin Laurent

Agriculture and Natural Resources Publications

A livestock watering area includes a watering facility and the heavy-use-area (HUA) surrounding it. Without protection, the HUA can develop surface depressions. Surface depressions can render the watering facility inaccessible and no longer frost-proof. Surface depressions also collect rainwater and excrement, creating mud and conditions adverse to livestock health (Figure 1).

Slaframine Toxicosis Or “Slobbers” In Cattle And Horses, Michelle Arnold, S. Ray Smith

Agriculture and Natural Resources Publications

An exceptionally wet summer weather pattern favors the growth of fungi on plants in the field and increases the risk for production of mycotoxins. Mycotoxins are naturally occurring compounds, some of which are toxic to cattle and horses, produced by fungi invading plant material. In the late 1940s and through the 1950s, beef and dairy producers and horse owners reported outbreaks of excessive salivation (slobbering) in cattle and horses associated with the consumption of second-cutting red clover (Trifolium pratense) and occasionally other legumes in the form of hay, pasture, or silage. It was not until the 1960s that …

Acute Or Atypical Interstitial Pneumonia (Aip), Michelle Arnold, Jeff Lehmkuhler

Agriculture and Natural Resources Publications

Acute or atypical interstitial pneumonia (AIP) is terminology used by veterinary pathologists to describe a characteristic pattern of damage in the lungs of cattle. At necropsy, the first indication of AIP-affected lungs is they fill the thorax and do not collapse like normal lungs when the chest cavity is opened. On further investigation, the AIP lungs are found to be semi-firm with a rubbery texture; not hard and consolidated as occurs in bacterial bronchopneumonia. Large air bubbles are found between portions of the lung (see Figure 1, “interlobular” or “bullous” emphysema) and the cut surface of the lung may appear …

Staggers (Tremorgenic Syndrome), Michelle Arnold

Agriculture and Natural Resources Publications

“Staggers” is an all-inclusive term for a group of nervous system disorders caused by indole-diterpenoid mycotoxins produced by various types of fungi on forages. These mycotoxins are collectively known as “tremorgens” (Table 1), and they may be found in several types of grasses at varying stages of maturity. The three main grass types associated with tremorgenic syndrome are Paspalum spp. (dallisgrass and bahiagrass), Cynodon dactylon (bermudagrass) and Lolium perenne (perennial ryegrass). Clinical signs are characterized by tremors and incoordination that tend to worsen with excitement or movement.

Lh-Independent Testosterone Secretion Is Mediated By The Interaction Between Gnrh2 And Its Receptor Within Porcine Testes, Amy T. Desaulniers, Rebecca A. Cederberg, Ginger A. Mills, J. Joe Ford, Clay A. Lents, Brett R. White

Department of Animal Science: Faculty Publications

Unlike classic gonadotropin-releasing hormone 1 (GNRH1), the second mammalian isoform (GNRH2) is an ineffective stimulant of gonadotropin release. Species that produce GNRH2 may not maintain a functional GNRH2 receptor (GNRHR2) due to coding errors. A full-length GNRHR2 gene has been identified in swine, but its role in reproduction requires further elucidation. Our objective was to examine the role of GNRH2 and GNRHR2 in testicular function of boars. We discovered that GNRH2 levels were higher in the testis than in the anterior pituitary gland or hypothalamus, corresponding to greater GNRHR2 abundance in the testis versus the anterior pituitary gland. Moreover, GNRH2 …

Life Cycle Assessment Of Alternative Swine Management Practices, Prathamesh Avadhut Bandekar

Graduate Theses and Dissertations

Life Cycle Assessments (LCAs) are quantitative analyses of complex systems for evaluation of impacts and risk associated with management decisions. LCAs can be effective tools for determining comparative advantages of management strategies across specific impact concern. In this study, life cycle assessments of pork production management alternatives was performed. The alternative management practices included in this study were production of entire males (boars), use of pens for gestation housing, immunocastration, production without growth promoting antimicrobials, production without growth promoting and preventive antimicrobials, and production without ractopamine. These LCAs evaluated the impact of each management strategy on greenhouse gas emission (GHG), …

Effect Of In Ovo Feeding Of Dextrin-Iodinated Casein On Hatch, Growth And Gene Expression In Broilers., Shaymaa Mostafa Ibrahim Abousaad

Graduate Theses and Dissertations

Six experiments were conducted to determine effects of in ovo feeding of dextrin (Dext, 18% maltodextrin, 10% potato starch dextrin) and iodinated casein (IC) on hatch and growth performance in broilers. In each experiment, approximately 15,000 eggs (2500 eggs per group) were treated at 18.5 to 19 d of embryonic development. Three studies indicated that hatch weights were higher in chicks receiving Dext or Dext containing IC at 240 or 480 µg/mL and only one study indicated negative effects of Dext or 240 µg IC/mL saline on hatch weight. In one growth study, broilers provided Dext or Dext with IC …

Introducing Green Manures In An Organic Soybean–Winter Wheat–Corn Rotation: Effects On Crop Yields, Soil Nitrate, And Weeds, Katja Koehler-Cole

School of Natural Resources: Dissertations, Theses, and Student Research

In organic soybean– winter wheat – corn rotations, animal manure is a common choice to maintain high yields, but leguminous crops grown as green manures after wheat harvest and incorporated into the soil before corn planting, can be an alternative when animal manure is not accessible. Forage legumes with high dry matter (DM) production and high biological N fixation have been shown to meet corn N demand. However, in Eastern Nebraska, lack of precipitation can reduce green manure growth and N fixation, leading to an insufficient N supply for corn, but corn growth can also be impacted by green manure …
