Nutrition Knowledge Of Pre-Medical Students, Jennifer Newcome, Cynthia Moore
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Nutrition knowledge has been shown to be increasingly critical in physician practice. Therefore, education has also become very critical. Medical schools have been working over the last few decades to include nutrition education in their curriculum, but due to many barriers, it is difficult to fulfil requirements. It is the purpose of this descriptive study to determine the nutrition knowledge of pre-medical students at the University of Arkansas and conclude if a nutrition class for these students would be beneficial. The average score of the nutrition knowledge assessment was 11.2 ± 3.04 out of a possible 23. Because the literature …

RNA interference (RNAi), a pathway capable of silencing genes, has until recently only been achievable in the laboratory by the use of one method, expression of inverted repeat sequences of DNA. These constructs generate a double-stranded RNA, which in turn induce post-transcriptional silencing of other genes that bear sequence homology with the transgene. This approach of targeted gene silencing is extremely useful for studying the function of genes and engineering new traits in both plants and animals. It has recently been discovered that a transgene lacking the polyadenylation signal, called a truncated transgene, is also capable of inducing RNAi in …

Ground cover mulch applications in perennial systems can have multiple benefits, one of which may be to enhance the size and diversity of the ground surface faunal community. To determine if ground cover and organic fertilizer applications altered invertebrate communities, litters in an experimental 0.4-ha organic apple orchard in Fayetteville, Ark. were sampled during a four week period beginning in February 2012. The orchard was planted in 2006 in a replicated 4 × 3 factorial design with organic ground cover and fertilizer treatments applied annually each April. Invertebrates were extracted using Berlese funnels and hand sorting techniques. Ground covers (wood …

Milling Characteristics Of High And Low Quality Rice, Alexandria Huck, Sarah Lanning, Terry Siebenmorgen
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Harvest moisture contents (HMCs) have been proven to play a role in rice quality, especially affecting head rice yield (HRY) due to fissuring or immature kernels. Differences in milling characteristics between samples having high and low level milling quality were studied in this experiment. Two hybrid, long-grain cultivars (CL XL729 and CL XL745) and two pureline, long-grain cultivars (CL 181 and Wells) were harvested at near optimal and low HMCs, representing high and low milling quality, respectively. Lots were dried to approximately 12.5 ± 0.5% and milled in triplicate for durations of 10, 20, 30, and 40 s. Results showed …

Our objective was to determine effects of aggressive handling on growth performance, behavior, and cortisol concentrations in beef calves. Crossbred calves (313 ± 4.7 kg; n = 54; 24 steers, 30 heifers) from a single herd were stratified by gender, body weight, and initial chute score, then allocated randomly to one of six pens. Each pen was randomly assigned to one of two handling treatments (good or adverse) applied on days 7, 35, 63, and 91. The objective of good treatment was to handle the calves quietly and gently to minimize stress. The objective of adverse treatment was to move …

The Arkansas Meat Goat Enterprise Budget, Jessica House, H. I. Goodwin
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Goats have long been the most populous livestock animals on the planet. They have been a staple food for many low-income countries. The United States has a growing demand for goat meat. There is an increase in ethnic cultures that desire goat meat as well as a growing interest from the general population. Goat meat is a healthy alternative compared to traditional red meats. Goats also pair well with other livestock animals due to their wide range of palatable feeds. They are commonly used in cattle operations for weed control because of their ability to consume noxious weeds. There is …

Female College Students’ Perception Of Self-Image Based On Fashion Magazine Advertising, Olivia Merritt, Kathleen R. Smith
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
The goal of this study was to examine how fashion magazine advertisements affect female college students’ perception of self-image. More specifically, do female college students have high or low self-image perception based upon the fashion magazine’s model images? Results of the study revealed female college students had positive perceptions of confidence with their physical body and body image. Before viewing the magazine advertising, participants liked their own body and would not change their body. However after viewing the magazine advertising, the participant’s confidence level decreased and participants liked their bodies less. While college women were not more likely to change …

The goal of this research was to determine the extent of resistance that turkey roundworms, Ascaridia dissimilis, have developed to anti-parasitic chemicals used in commercial poultry operations. Roundworm infections in turkeys have resulted in monetary losses for the poultry industry for years, generally due to poor feed conversion. The infection itself is subclinical and many turkeys have a light to moderate worm burden. Since parasitisms are light, this leads to the infections being noticed only during processing. Ascaridia dissimilis infections consist of adult worms and developing larvae with the latter comprising most of the worm burden and causing the most …

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Dietary conjugated linoleic acid (CLA) is known to be effective in avoiding many obesity related diseases. Conjugated linoleic acid is a product of ruminant fermentation and 3.4 g/day are needed to obtain the clinical benefits. However, it is difficult to obtain sufficient CLA to realize these benefits from a healthy diet containing dairy and beef products, without increasing levels of dietary cholesterol and saturated fat. A 20% CLA soy oil with low saturated fat and no cholesterol has been produced by photoisomerization of linoleic acid in the triacylglyceride oil. Further increasing the CLA yields has been possible by addition of …

Prune consumption has been associated with a decreased risk of colon cancer; yet there has been confusion as to which chemical component(s) of the prune are responsible for its anticarcinogenic properties. Previous studies have evaluated chlorogenic acid as a chemotherapeutic agent; however, only a limited amount of studies have investigated neochlorogenic acid, the predominant phenolic compound found in the prune. The purpose of this study was to determine the effects that chlorogenic acid and neochlorogenic acid have as anticarcinogenics on the human adenocarcinoma, Caco-2 cell line. The anti-colon cancer effects of chlorogenic acid and neochlorogenic acid were analyzed by experiments …

The Evolution Of Rural Farming In The Scottish Highlands And The Arkansas Delta: Investments And Inequalities, Madalyn Watkins, Lanier Nalley
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
The development and evolution of an agricultural system is influenced by many factors including binding constraints (limiting factors), choice of investments, and historic presence of land and income inequality. In this study, we analyzed the development of two farming systems: expansive, mechanized farming in the Arkansas Delta and crofting in the Scottish Highlands. We hypothesized that the current farm size in each region can be partially attributed to the binding constraints of either land or labor. The Induced Innovation Model and the Gini coefficient were employed in the analysis of data pertaining to the respective regions’ agricultural constraints, investments, and …
