Evaluating The Effectiveness Of Utah Farm Field Days, Paige Wray

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Utah farm field day events seek to increase agricultural literacy among elementary students. Although these events are occurring statewide, no formal evaluation has been conducted to determine student increases in agricultural literacy related to these events. The purpose of this study was to evaluate two such events to see what students knew about agriculture before they attended the farm field day, what they wanted to learn about concerning agriculture, and what they learned after attending the event. Results showed that these children were below average for expected grade level understandings or agricultural awareness before the event. However, after the event, …

Evaluation Of Absorbezz On Swine Reproductive Health And A Comparative Study Of Two Commercially Available Swine Show Feeds, Scott G. Sutton

Electronic Theses and Dissertations

The efficacy of a feed supplement fed to gilts and sows was tested in study I. The supplement was stated to improve reproductive soundness, conception rates, immune health, and overall well-being of livestock. Thirty gilts were split into a control group (Base diet) and a treatment group (Absorbezz® 0.32 mL on base diet). Upon completion of the trial results indicate the treatment group significantly underperformed (

Backyard Poultry Biosecurity, Joshua Dallin, Denton Perkins

All Current Publications

Biosecurity is taking measures to protect animals and humans from harmful biological agents. In commercial poultry production, this generally means total confinement operations with strict rules to maintain flock health such as shower-in and out systems, special clothing, and other measures. In small production or “backyard” poultry operations these measures aren’t always a reality. However, there are steps that should be taken to help promote biosecurity and safety for backyard flocks, and these are discussed in this fact sheet..

Farm Food Safety Laws: Fsma Vs. Gap, Shawn Olsen, Karin Allen

All Current Publications

This fact sheet describes the differences in the farm food safety laws, FSMA and GAP. The FDA Food Safety Modernization Act (FSMA) includes a Produce Safety Rule that became final in November, 2015 (U.S. Food and Drug Administration, 2015). The rule establishes minimum standards for the safe growing, harvesting, packing, and holding of fruits and vegetables grown for human consumption. All covered growers will need to comply with FSMA as it is a federal law. GAP is a voluntary audit program designed to verify that produce is grown, packed, handled, and stored as safely as possible.

Effects Of Damaged Starch In Wheat Flour On Qualities Of Frozen Cooked Noodles, Yue Fengling, Zhu Kexue, Guo Xiaona

Food and Machinery

In order to determine the effects of damaged starch in wheat flour on the quality of frozen cooked noodles, starch was isolated from wheat flour and then ball milled to obtain damaged starch. The damaged starch was added into wheat flour with a certain percentage. The effects of damaged starch on the pasting properties and swelling power of wheat flour, as well as on the cooking qualities, texture properties, amount of freezable water and microstructure observed by confocal laser scanning microscopy(CLSM) of frozen cooked noodles were investigated. Results showed with the increment of damaged starch content from 4.3% to 7.9%, …

Structural Properties Of Potato Resistant Starches Modified By A Combination Of Organic Acid And Heat-Moisture Treatments, Zhou Hui, Xie Tao, Jiang Zhaohui, Yi Cuiping

Food and Machinery

Resistant starches from potato (RS3) were modified by acid hydrolysis combined with heat-moisture treatment (AH-HMT). The effects of changing the starch slurry concentration, the type of acid and its concentration on the structure of RS3 were also studied. The results showed that after AH-HMT, the X-ray pattern remained practically the same with only small changes in the average degree of polymerization (DP), specific surface area (SSA), microstructure (MS), and relative crystallinity (RC). Compared with untreated RS3, the decrease in DP and SSA and the increase in RC caused by high concentrations of acid were significantly greater than those caused by …

The speciation analytical method was developed to detect the arsenic (As) and research its styles, contents and distribution in Acori tatarinowii. The arsenic speciation was separated by high performance liquid chromatograph with anion exchange column (HAMILTON PR-X100, 4.1 mm×250 mm，10 μm). Mobile phases were ultra-pure water (A) and 50 mmol/L ammonium carbonate with 1% methanol（pH 8.5, B）. Inductively coupled plasma emission and mass spectrometry was involved to detect arsenic speciation. The linear ranges were between 0.995 and 0.999, and the rate of recovery ranged from 89% to 97%. The method was confirmed to be accurate, stable and reliable. The results …
