The Development Experience Of British Food Gdas Labeling And Several Enlightenments To China, Huang Ze-Ying, Huang Bei-Xun

Food and Machinery

This study carried out a case study on food GDAs （Guideline Daily Amounts） labeling in British. It was found that GDA_S labeling which has been implemented for over 20 years, changed from BOP （Back of Package） labeling to FOP labeling. The labeling shows the amount of energy, sugar, fat, saturated fat, and salt per serving, as well as the percentage of the recommended daily intake by using the specific nutrient system measurement model. The labeling lacks of color coding and visual icon, and its implementation is not as effective as most FOP labels. Therefore, it is suggested to display …

Incentivizing Wellness Through Community Supported Agriculture: Reflections On Shareholder Impacts Of An Employer-Based Csa Voucher Program, Jairus J. Rossi, Timothy A. Woods

Agricultural Economics Faculty Publications

Community supported agriculture (CSA) programs are emerging as popular consumer options for pro­duce acquisition. While many researchers have dis­cussed the impacts of CSA on economies, commu­nities, and the environment, others are interested in documenting how produce-based CSA shapes health. In this paper, we evaluate whether and to what extent CSA incentive programs, funded by diverse employer groups in central Kentucky 2015–2018, impact shareholder wellness. To evaluate impact, we use two distinct types of data: we com­pare shareholders’ perceived frequency of food lifestyle behaviors from pre- and post-season sur­veys, and we examine anonymized medical claims from a subset of these participants …

Using Uav Technology Paired With Multispectral Cameras To Assess Crown Rust Epidemics In Oats, Turner A. Graham

LSU Master's Theses

Crown rust, caused by Puccinia cornonata f. sp. avenae, is a common disease of oats (Avena sativa) found virtually everywhere oats are cultivated. This disease has caused yield losses of 10 to 40% worldwide. Early detection is important for effective management. A more recently utilized technology in agriculture is unmanned aerial vehicles (UAVs). UAVs, or drones, equipped with cameras are now being used as a resource to take images of fields to identify pests and other issues that may be occurring. Normalized differentiated vegetative index (NDVI) is a numerical indicator used to determine the vegetative health of …

Evaluating Substrate Stratification Practices For Enhanced Water Resource Management In Nursery Production, Kristopher S. Criscione

LSU Master's Theses

The nursery and greenhouse industries have continued to increase in production and sales over the past two decades. This increase in horticultural production necessitates a greater demand for finite natural resources, specifically water. Sustainable water resource management will be critical to the success and continual growth of the nursery industry. Strategic irrigation scheduling and innovative substrate management practices can improve nursery resource efficiency. Soilless substrates were originally utilized by the industry to increase substrate air-filled porosity, to ensure adequately drained container systems. Thus, the implementation of these soilless substrates can lead to an inefficient use of water and fertilizer. Substrate …

Casting A Critical Lens On Global Development: A Multimethod Investigation Of The Masculine Hegemonic Forces That Marginalize Women In Agriculture, Morgan Alyse Richardson Gilley

LSU Doctoral Dissertations

A critical link between gender equality and agricultural development has been established in the literature. However, disparities between genders have persisted in many areas of the developing world. One strategy that has been used to reduce gender inequalities has been educational outreach opportunities through agricultural extension, which has provided women a critical pathway to empowerment. Despite this, a lack of knowledge on the experiences of women in agriculture throughout Southeast Asia has served as a barrier to the advancement of such work. This investigation sought to better understand the issues facing this region’s fight to attain gender equality. To achieve …

University Research On Winter Growing Of Container-Grown Strawberries Translates To Grower's Farm Trial, Stacy A. Adams, Ellen T. Paparozzi, Ryan Pekarek, Dave P. Lambe, George Meyer, M. Elizabeth Conley, Paul Read

Department of Agronomy and Horticulture: Faculty Publications

Strawberries are only seasonally available in Nebraska (NE). If an affordable heated structure can be designed, then opportunity exists to increase on-farm income by producing strawberries off-season during high-value market periods. A series of university greenhouse trials were conducted from 2010 to 2012. The varieties Evie-2 and Seascape were identified as being most productive under a low technology growing scheme. A new research project, which ran from fall to late spring (2013–2014), was designed to determine if this production scheme would translate to a commercial grower. Varieties Seascape and Evie-2 (each at two grades indicated by +) and San Andreas …

Growing Faba Beans On The South Coast Of Western Australia, Sarah Belli, Carla Milazzo, Emma Pearse, King Yin Lui, Grace Williams, Jeremy Lemon

Grain and other field crops published reports

Editors: Megan Abrahams, Andrew Blake and Vanessa Stewart (DPIRD)

Foreword

Thirty-three years ago I started work in Esperance on broadleaf crops. One of the best things my boss set up for me was arranging visits with several lupin farmers so I could follow their crops from seeding, through the growing season, to harvest. It was a great way to quickly get an idea of the choices farmers make and the reasons why.

With today’s busy lives, most farmers would be hard pressed to have the luxury of visiting many other farmers multiple times to learn how to grow a crop. …

The Effects Of Omega-3 Pufa Infusions During Late Gestation On Developmental Pathologies In The Intrauterine Growth Restricted Fetus, Taylor A. Lacey

Department of Animal Science: Dissertations, Theses, and Student Research

Low birthweight due to intrauterine growth restriction is associated with metabolic disorders after birth. Our 1^st study assessed deficits in skeletal muscle glucose metabolism and pancreatic β cell function in IUGR fetal sheep. We aimed to evaluate the effectiveness of daily intravenous infusions of the anti-inflammatory ω-3 polyunsaturated fatty acid (PUFA), eicosapentaenoic acid (EPA), as a means of improving deficits previously observed in the IUGR fetus by targeting fetal systemic inflammation. The presence of systemic inflammation in IUGR fetuses was evident by increased total circulating populations of total leukocytes, lymphocytes, and monocytes. However, these were …

The Effect Of Natural Elicitors And Cold Storage Period On Quality Improvement Of Uae Date Palm Fruits (Phoenix Dactylifera, Cv. Barhi), Fatima Yaaqoub Yousef Al Shaibani

Theses

Date palm is an agricultural crop of economic importance in most Arab countries. Among the different varieties of date palms grown in the United Arab Emirates, the Barhi variety is extremely popular and is often consumed at the bisr stage (first edible stage). However, the major challenge for this fruit at bisr stage is to maintain its quality over a long period after harvest and during marketing. The objective of this study was to evaluate the synergistic effect of preharvest spraying with a natural elicitor, namely chitosan (Ch) 1%, alone and in combination with salicylic acid (SA) 2 mM and …
