Stock Market Reactions To Unfavorable Product Information: A Case Study Of Comments On Beef Safety Made On An Oprah Winfrey Show, Elpida Ormanidou, Michael Thomsen Jan 2000

Stock Market Reactions To Unfavorable Product Information: A Case Study Of Comments On Beef Safety Made On An Oprah Winfrey Show, Elpida Ormanidou, Michael Thomsen

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

This study examines the impact of unfavorable media coverage on the stock market prices of major food companies, an issue of increasing importance to the food industry. The study focuses on the 16 April 1996 Oprah Winfrey Show, a popular television program that raised questions about the safety of the U.S. beef supply. The show resulted in considerable controversy, and some cattle feeders blamed the show for a drop in cattle prices. The focus of this study is on the impact of the program at other stages of the food system. We examined the stock returns of two major beef …

Determination Of Chilling Requirement Of Arkansas Thornless Blackberry Cultivars, Chrislyn A. Drake, John R. Clark Jan 2000

Determination Of Chilling Requirement Of Arkansas Thornless Blackberry Cultivars, Chrislyn A. Drake, John R. Clark

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Little research has been done to determine the chilling requirement for blackberry cultivars. However, field observations from areas where fewer hours of chilling occur indicate that ‘Navaho’ requires more hours of chilling than does ‘Arapaho’. The objective of our study was to determine a method for measuring the chilling requirement using whole plants of two blackberry cultivars, Arapaho and Navaho. One-year old, bare-root plants were field-dug on 26 October 1999 and placed in a cold chamber at 3ºC. Ten single-plant replications of each cultivar were removed at 100-hour intervals up to 1000 hours. The plants were potted and placed in …

Feasibility Of Inducing Overlap Immunologic Competence In Gallinaceous Birds With Ascardia Dissimilis And A. Galli, Julie Hamilton, Thomas A. Yazwinski Jan 2000

Feasibility Of Inducing Overlap Immunologic Competence In Gallinaceous Birds With Ascardia Dissimilis And A. Galli, Julie Hamilton, Thomas A. Yazwinski

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Chickens and turkeys are routinely infected with the roundworms Ascaridia galli and A. dissimilis, respectively. The current study was conducted to gather basic information on these worms and to determine whether heterologous infections (chicken worms in turkeys and turkey worms in chickens) would be successful. Chickens and turkeys were obtained at day of hatch, brooded to 7 days of age, and placed in pens (25/pen) according to infection as received at 7 days of age: homologous, heterologous and control (no infection). Bird weights, mortalities, and feed efficiencies were monitored for 3 weeks postinfection, at which time all birds were killed …

Reproductive Behavior Of The Emu, Reema A. Persad, Douglas James, Nicholas B. Anthony Jan 2000

Reproductive Behavior Of The Emu, Reema A. Persad, Douglas James, Nicholas B. Anthony

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Members of a flock of male and female emus were observed in an ethological experiment designed to investigate trends in reproductive behavior exhibited during the North American mating season, which lasts from October to mid-March. Observations were made at dawn, noon, and dusk from December 1999 to mid-March 2000, and the only behaviors that were consistently expressed during these times were pecking, strutting, exclusive, and male and female sexual activities (defined in text). Though statistical significance was found between male strutting behavior and female sexual activity in the December observation period, no overall significance or significance at other observation periods …

Growth And Performance Of Broiler Chicks During The Starter And Grower Phases In Phase-Feeding, L. Niki Loupe, Jason L. Emmert Jan 2000

Growth And Performance Of Broiler Chicks During The Starter And Grower Phases In Phase-Feeding, L. Niki Loupe, Jason L. Emmert

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

An experiment was conducted to evaluate the efficacy of a nutrition program referred to as “phase-feeding” (PF) over the first 6 weeks posthatching. Diets were formulated using amino acid recommendations from the National Research Council (NRC) (1994) or from linear regression equations generated from best estimates of lysine (Lys), sulfur amino acid (SAA), and threonine (Thr) requirements. Regression equations were used to predict weekly Lys, SAA, and Thr requirements for use in a PF regimen that involved lowering amino acid levels following each respective week of the experiment, resulting in six diets fed over the 6-week period. Over the entire …

Livability Of Leghorn Balut Embryos Stored Under Varying Temperatures And Storage Times, Joyce Jong, F. Dustan Clark Jan 2000

Livability Of Leghorn Balut Embryos Stored Under Varying Temperatures And Storage Times, Joyce Jong, F. Dustan Clark

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Baluts are fertile chicken or duck eggs that have been incubated and removed from the incubator prior to hatching for consumption. Chicken eggs are incubated for 11 to 14 days and duck eggs are incubated for 16 to 20 days. Baluts have an extremely specialized consumer market, with the majority of its consumers of Filipino decent. Current U.S. Department of Agriculture regulations for the storage of baluts prior to sale is 7.2ºC, the same as for infertile commercial table eggs. Consumer preference is to purchase live baluts for consumption. Since exposure to 7.2ºC causes embryo mortality within 8 hours of …

Prediction Of Rice Sensory Texture Attributes Using Spectral Stress Strain Analysis And Jack-Knife Model Optimization, Marura Lenjo, Jean-Francois Meullenet Jan 2000

Prediction Of Rice Sensory Texture Attributes Using Spectral Stress Strain Analysis And Jack-Knife Model Optimization, Marura Lenjo, Jean-Francois Meullenet

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Sensory texture characteristics of cooked rice were predicted using an extrusion test and a novel multivariate analysis method. Eleven sensory texture characteristics were evaluated via a trained descriptive panel and predicted for force/deformation spectra with partial least squares regression. Only four sensory attributes—adhesion to lips (Rcal = 0.83), cohesion of bolus (Rcal = 0.78), cohesiveness (Rcal = 0.69), and hardness (Rcal = 0.72)—were successfully predicted from instrumental measurements.

Fissure Characterization Of Rice Kernels Using Video Microscopy, Jerry W. Fendley, Terry J. Siebenmorgen, Rustico C. Bautista Jan 2000

Fissure Characterization Of Rice Kernels Using Video Microscopy, Jerry W. Fendley, Terry J. Siebenmorgen, Rustico C. Bautista

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Fissures are fractures of a rice kernel that can be created during the drying and tempering process. They cause tremendous postharvest losses in milling yield. Understanding why and how rice kernels fissure will lead to optimal drying and tempering operations. This information could also provide input to plant breeders for producing rice cultivars that are more resistant to fissuring. Rice kernels were dried using various air conditions in a controlled environment chamber. The kernels were viewed by video microscopy to observe the occurrence of fissures. A videocassette recorder recorded the images for a 24-hour period after the drying process. The …
