Physicochemical Properties And Leaching Behavior Of Eight U.S. Long-Grain Rice Cultivars As Related To Rice Texture, Devon Cameron, Ya-Jane Wang
Physicochemical Properties And Leaching Behavior Of Eight U.S. Long-Grain Rice Cultivars As Related To Rice Texture, Devon Cameron, Ya-Jane Wang
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
There are many long-grain rice cultivars produced commercially in the U.S.; however, little work has been done on correlating the structure and physicochemical properties of starch with their texture. The physicochemical properties, leaching behavior, and texture attributes of eight longgrain rice cultivars were studied. Differences were observed in the approximate composition of kernels, including crude protein (6.6-9.3%), crude lipid (0.18-0.51%), and apparent amylose content (25.5-30.9%). These cultivars also differed slightly in thermal properties, such as onset temperature (73.7° to 77.4°C) and peak temperature (78.8° to 81.9°C). Although they showed a similar pasting temperature, their peak viscosities ranged from 680 to …

Infectious bursal disease virus (IBDV) is a pathogen that primarily infects B lymphocytes in domestic avian species. This viral infection has been associated with immunosuppression, clinical disease/mortality, and enteric malabsorption effects. The purpose of this experiment was to compare the effects of a classic (USDA-STC) and a new variant IBDV (RB-4, known to induce primarily the enteric disease) on immune cell populations in lymphoid organs. Seventeen-dayold specific-pathogen-free (SPF) White Leghorn chickens were either not infected (control) or inoculated with either USDA-STC or RB-4 IBD viral isolate. On days 3 and 5 post-inoculation (PI), lymphoid tissues were collected to prepare cell …

An experiment was conducted to assess effects of phase-feeding (PF) on crude protein (CP) intake, excretion, and retention of broilers. Six birds were housed individually and were fed diets formulated using recommendations from National Research Council (NRC) or linear regression equations. Two PF treatments were prepared: standard (PF) and low (PF10), in which predicted lysine, sulfur amino acids, and threonine recommendations were reduced by 10%. For PF and PF10, two diets (high-nutrient and low-nutrient density) were blended in variable quantities to produce rations matching predicted amino acid requirements over two intervals. Birds were fed a single NRC grower and finisher …

Few fruit thinners have been certified for organic fruit growers. Previous studies have shown that herbicides or shade are capable of reducing photosynthesis and are effective fruit-thinning techniques, although impractical. This project evaluated use of a model plant system of vegetative apple trees grown under controlled conditions to study photosynthetic inhibitors, which could be used as potential organic thinning agents. Various concentrations of osmotics, salts, and oils (lime-sulfur, potassium bisulfite, potassium bicarbonate, sodium chloride, soybean oil) were applied to actively growing apple trees and showed a reduced trend on the rate of apple tree photosynthetic assimilation (Pn), evapotranspiration (Et), and …

The melanocortin 1-receptor (MC1-R) gene plays a key role in the expression of fur and feather color in mammals and birds by regulating the distribution of two melanin pigments: eumelanin (black/brown) and pheomelanin (red/yellow). MC1-R corresponds to the classical Extension (E) locus in mice, pigs, dogs, horses, and chickens. Three E locus alleles, the wild-type (e+), brown (E), and redhead (erh) have been identified in Japanese quail (Coturnix japonica). To determine if the quail E locus phenotypes were due to variation in the MC1-R gene, the coding region of the MC1-R gene was PCR amplified and DNA sequenced using genomic …
