Optimizing The Feeding Time For Low Crude Protein, Amino Acid-Supplemented Diets For Broilers, Stephen T. Treese
LSU Master's Theses
The objectives of this research were to determine whether delaying the feeding of a diet with reduced crude protein, supplemented with L-Lysine, for several days post-hatching, would result in improved growth performance of broiler chicks and determine an optimal time to feed such a diet to the chick. All experiments were conducted in brooder batteries from 0- to 14- or 18- days (d) post-hatching. Treatments contained a minimum of 6 replicate pens with at least 6 broilers per pen. Two experiments were conducted to determine whether delaying the feeding of a corn-soybean meal (SBM) diet with reduced CP for either …
The Role Of Motivation And Physical Activity In A Weight Loss Program, Ellen Kane Stevens
The Role Of Motivation And Physical Activity In A Weight Loss Program, Ellen Kane Stevens
LSU Master's Theses
Every year thousands of overweight and obese people in the United States join weight loss programs such as Weight Watchers in an effort to become healthier and feel more attractive. Weight Watchers has increased its program focus on physical activity as a critical part of weight loss. Initiating a consistent physical activity routine, however, is generally one of the last behavior changes made by program members, despite its proven role in weight loss maintenance. Using self-determination theory as a framework, the purpose of this study was to examine how perceptions of fulfillment of three psychological needs (i.e. competence, autonomy, and …
Inhibitory Effects Of Berry Anthocyanins On Palmitic Acid- Or Lipopolysaccharide- Induced Inflammation In Human Preadipocytes, Chenfei Gao
LSU Master's Theses
Obesity is an inflammatory disease associated with the development and progression of chronic degenerative diseases including insulin resistance, cardiovascular disease (CVD), type 2 diabetes mellitus (T2DM), and cancer. Circulating free fatty acid (FFA) are known risk factors promoting inflammation that can lead to CVD. Pre/adipocytes are known storage of low grade inflammatory biomarkers associated with obesity. However, the effects of dietary anthocyanins on inflammatory biomarkers in preadipocytes have not been reported. Berries are rich sources of naturally occurring antioxidant polyphenolics. There is increasing interest in the ability of berry anthocyanins to provide health benefits against obesity. Anthocyanins were isolated from …

LSU Master's Theses
Blueberries have received considerable attention due to their content of health promoting compounds such as polyphenols and anthocyanins. Thermal pasteurization (TP) is known to cause degradation of anthocyanins and juice color. Microencapsulation, particularly with incorporation of blueberry antioxidants, can improve the stability of menhaden (MO) and salmon (SO) fish oils rich in omega-3 fatty acids. The objectives of this research were to study the effect of TP and continuous ultrasonication processing on the microbiological, chemical and physical properties of blueberry juice (BJ) and to determine the effect of BJ on MO and SO lipid oxidation during microencapsulation. Fresh blueberries were …
Sources Of Self-Efficacy In Distance Runners, Ashley Ann Samson
Sources Of Self-Efficacy In Distance Runners, Ashley Ann Samson
LSU Doctoral Dissertations
Self-efficacy theory (Bandura, 1997) asserts that people will be more likely to engage in behaviors that they believe they can successfully perform and avoid behaviors in which they feel that they will be unsuccessful. Researchers have concluded that individuals with high levels of self-efficacy are more likely to pursue challenging goals, cope with pain, and persevere through setbacks, while those with low self-efficacy avoid challenges and tend to give up when confronted with obstacles (Llewellyn, Sanchez, Asghar, & Jones, 2008). Endurance sport, particularly distance running, is a domain in which being able to cope with pain and persevere through setbacks …
Influence Of Low Sonication Intensities At Different Temperatures On Acid Tolerance, Bile Tolerance, Protease Activity And Growth Of Yogurt Culture Bacteria Lactobacillus Delbrueckii Ssp. Bulgaricus And Streptococcus Salivarius Ssp. Thermophilus, Marvin L. Moncada Reyes
LSU Master's Theses
Streptococcus salivarius ssp. thermophilus and Lactobacillus delbrueckii ssp. bulgaricus are dairy cultures widely used in the dairy industry. Low sonication intensity condition is a non-destructive technique that uses sound waves to cause cavitation in aqueous solutions and may improve the permeability of membranes, speed up the transfer of substrates and promote cellular growth and propagation. The objective of this study was to determine the effect of low sonication intensities at different temperatures on acid tolerance, bile tolerance, protease activity and growth of the two dairy cultures. The cultures were freshly thawed and suspended in 0.1% peptone water and 18 ml …
Contribution Of Bacillus Thuringiensis Cotton Cultivars And Insecticides To A Fall Armyworm, Spodoptera Frugiperda (J. E. Smith), (Lepidoptera : Noctuidae) Management Strategy, Jarrod T. Hardke
LSU Doctoral Dissertations
Fall armyworm, Spodoptera frugiperda (J. E. Smith), response to cottons, Gossypium hirsutum L., expressing Bacillus thuringiensis (Bt) insecticidal proteins, Cry1Ac (Bollgard®), Cry1Ac + Cry2Ab (Bollgard II®), and Cry1Ac + Cry1F (WideStrike™), was evaluated in field and laboratory experiments. In field trials, larvae that were infested on selected fruiting forms (squares, white flowers, and bolls) of WideStrike™ plants had lower survivorship and caused less injury than larvae on non-Bt plants, regardless of fruiting structures. Bollgard® and Bollgard II® plants produced no consistent negative effects on fall armyworm survivorship and injury. In no-choice laboratory assays, Bollgard II® and WideStrike™ cotton tissue reduced …
Comparison Of Disk Diffusion, Agar Dilution, And Broth Microdiultion For Antimicrobial Susceptibility Testing Of Five Chitosans, Lin Jiang
LSU Master's Theses
Chitosan is a polysaccharide biopolymer with excellent biocompatibility, biodegradability, and low toxicity, which allows for potential wide applications. Recently, antimicrobial activities of chitosan against foodborne pathogens have been studied; many used disk diffusion to determine the activity. However, this method is unable to obtain minimal inhibitory concentrations (MICs), i.e., not quantitative. The objective of this study was to compare disk diffusion with agar dilution and broth microdilution, two quantitative methods used routinely in clinical laboratories, to determine MICs of chitosan against foodborne pathogens. Five chitosan compounds with molecular weights ranging between 43 and 1,100 kDa were tested against 36 representative …
Characterization Of The Subcortical Interactions Between Larvae Of The Southern Pine Sawyer Monochamus Titillator (F.) And The Larvae Of The Southern Pine Beetle Guild Using Molecular Gut Analyses, Erich N. Schoeller
LSU Master's Theses
The southern pine beetle guild (Coleoptera: Curculionidae: Scolytinae) is arguably the most destructive group of forest pests in the Southeastern United States. Laboratory assays suggest that larvae of wood borer associates from the genus Monochamus (Coleoptera: Cerambycidae) may be facultative intraguild predators of southern pine beetle guild. In this study the dynamics of the subcortical interactions between M. titillator (F.) and members of the southern pine beetle guild were examined using PCR-based molecular gut content analyses. Species-specific PCR primer sets were developed to work under multiplex PCR conditions to detect DNA of members of southern pine beetle guild in the …

Spray Drying Technology For The Production And Processing Of Microencapsulated Omega-3 Fish Oil With Egg Powder, Kevin Estuardo Mis Solval
LSU Master's Theses
Protein with essential amino acids is required for recovering, repairing, and building muscles after intensive exercise. A powder produced with egg white (EW) (high quality protein) and fish oil (menhaden (Brevoortia patronus) (MO) oil or salmon oil (SO)) with high DHA and EPA content should be particularly beneficial for athletes. The objective of this study was to develop microencapsulated omega-3 fatty acids fortified EW powders. Two stable emulsions were prepared with 3.43% (MO) or (SO), 56.21% EW, and 40.36% water (E-MO-EW and E-SO-EW). An EW with water solution (without fish oil) (E-EW) was prepared as a control. Two emulsions (E-MO-EW; …
A Systematic Study Of Xylella Fastidiosa Strains Isolated From Pecan, Grapevine, Oleander, And Sycamore In Louisiana, Rebecca Ann Melanson
A Systematic Study Of Xylella Fastidiosa Strains Isolated From Pecan, Grapevine, Oleander, And Sycamore In Louisiana, Rebecca Ann Melanson
LSU Master's Theses
Xylella fastidiosa causes disease in a number of economically important crops and landscape shrubs and trees including grapevine, citrus, oleander, and sycamore. In pecan, X. fastidiosa causes pecan bacterial leaf scorch (PBLS), which leads to defoliation and reduces nut yield. No economically effective treatments are available for PBLS. In order to improve PBLS management practices, it is necessary to determine the subspecies of X. fastidiosa strains that infect pecan so potential sources of inoculum can be identified. Multiprimer PCR and phylogenetic analyses using nucleotide sequence data from the 16S-23S rDNA intergenic transcribed spacer (ITS) region and pglA consistently identified strains …

Characterization And Utilization Of Rice Defense Associated With Partial Resistance To Bacterial Panicle Blight: An Emerging Rice Disease Problem In The Southeastern United States, Bishnu Kumar Shrestha
LSU Master's Theses
Rice is a staple food for much of the world’s growing population. Rice production is limited by a number of abiotic and biotic factors. These factors have direct effects on food security because less food is available to growing population. Bacterial panicle blight (BPB), caused by the bacterium Burkholderia glumae, is an emerging disease that causes grain rot, panicle discoloration, and unfilled grains in rice. Up to 70% of yield reduction has been reported in severely infected rice fields. No completely resistant rice cultivars have been identified, however, a medium-grain cultivar, Jupiter, showed a high level of partial resistance …
Examining The Perceptions Of Teachers' Efficacy In Handling Student Misbehavior (Tehsm) In Classroom And Physical Education Settings, Costas Nicou Tsouloupas
Examining The Perceptions Of Teachers' Efficacy In Handling Student Misbehavior (Tehsm) In Classroom And Physical Education Settings, Costas Nicou Tsouloupas
LSU Doctoral Dissertations
Research has found dealing with student misbehavior as the most prominent source associated with teachers’ negative behavioral outcomes at work. One approach for understanding teachers’ behavioral responses to student misbehavior is through the efficacy beliefs of teachers. This line of inquiry has lead to the advancement of the concept of teacher efficacy in handling student misbehavior or TEHSM. TEHSM was found to significantly and negatively mediate the relationship between teachers’ perception of student misbehavior, emotional exhaustion, and turnover intentions respectively. To date, limited information is available regarding the makeup of TEHSM which gives emphasis to the significance of this dissertation. …
Molecular Mechanisms Of Bacillus Thuringiensis Resistance In The Sugarcane Borer, Yunlong Yang
Molecular Mechanisms Of Bacillus Thuringiensis Resistance In The Sugarcane Borer, Yunlong Yang
LSU Doctoral Dissertations
The sugarcane borer, Diatraea saccharalis, is a major target pest of transgenic corn expressing Bacillus thuringiensis (Bt) proteins in many areas of the U.S. mid-southern region. A Cry1Ab-resistant (Cry1Ab-RR) strain of D. saccharalis has been developed from a single two-parent family-line. To examine the molecular mechanisms of the Cry1Ab resistance in this insect strain, cDNAs of five types of potential candidate genes related to Bt resistance were sequenced using reverse transcriptase polymerase chain reaction (RT-PCR) and 5’ rapid amplification of cDNA end (5’ RACE). The Bt resistance candidate genes examined included three trypsins (DsTRYs), three chymotrypsins (DsCHYs), three aminopeptidases N …
Changes In Select Phenolic Compounds During Ethanol Fermentation And Acetification Of Raspberry, Blueberry And Persimmon, Yen-Ping Tan
Changes In Select Phenolic Compounds During Ethanol Fermentation And Acetification Of Raspberry, Blueberry And Persimmon, Yen-Ping Tan
LSU Master's Theses
Polyphenols are major dietary components in fruits and vegetables. Many research and epidemiological studies have reported that phenolic compounds, such as anthocyanins, may have a protective effect against various degenerative diseases. Phenolics in grape wine have been extensively studied but information on changes of phenolics in wine and vinegar made from other fruit crops is limited, however. This research started with the objective of determining the effect of proteases in preventing phenolic and, specifically, anthocyanin degradation in the ethanolic fermentation of black raspberries to reduce sugar content. The results of this study led to investigations of changes of other polyphenols …
Ecology And Systematics Of Coleoptera In Woody Debris Of Eastern North American Forests, Michael Leslie Ferro
Ecology And Systematics Of Coleoptera In Woody Debris Of Eastern North American Forests, Michael Leslie Ferro
LSU Doctoral Dissertations
Dead wood is a largely unexplored reservoir of taxonomic diversity and its ecology is poorly known despite its use as fuel and its roles in the carbon cycle and healthy ecosystems. During this research 15 new species of dead wood associated rove beetles (Staphylinidae: Pselaphinae) in the genus Sonoma Casey were discovered and described. Sonoma tolulae (LeConte) was redescribed. Taxonomic issues obfuscated the identity of another dead wood associate, Thoracophorus costalis (Erichson) (Staphylinidae: Osoriinae). Examination of holotypes resulted in the discovery of two nomenclatural synonyms: T. longicollis Motschulsky, and T. fletcheri Wendeler. An inexpensive emergence chamber used to collect insects …
