Evaluation Of Low-Tannin Grain Sorghum In Broiler Chicken Diets, Samantha Aniecia Shelton
Evaluation Of Low-Tannin Grain Sorghum In Broiler Chicken Diets, Samantha Aniecia Shelton
Graduate Theses and Dissertations
Research trials were conducted to evaluate the effects of different levels of dietary grain sorghum on broiler live performance, carcass yield and shank (leg) and breast skin coloring. Iso-caloric diets were formulated where sorghum replaced corn at rates of 0% (control), 20, 40, 60, 80 and 100% for a total of 6 diets. For each of the two trials, 1500 Cobb 500 male broiler chicks were randomly allocated to 60 pens with 25 birds per pen (10 pens/diet) and grown to 46 days for the first research trial and 41 days for the second. There were no differences (P>.05) …
Intuitive Eating, Attitudes To Food, And Body Size: A Comparison Between Nutrition Majors And Non-Majors, Katelyn Russell
Intuitive Eating, Attitudes To Food, And Body Size: A Comparison Between Nutrition Majors And Non-Majors, Katelyn Russell
Masters Theses
Dietitians are expected to deliver sound and scientifically objective advice to the general public, yet their personal beliefs and behaviors could influence delivery of nutrition care. Increased understanding of the personal attitudes and behaviors of dietitians concerning eating behavior and body image could help improve dietetic practice. Traditional nutrition education emphasizes cognitive eating, i.e., monitoring energy intake and comparing macronutrient intakes to the current acceptable ranges. Intuitive eating, however, promotes the release of cognitive eating in favor of greater attention to physiologic cues, or “body wisdom”. We hypothesized that nutrition students in a traditional curriculum would report eating less intuitively …
Effects Of Acute And Chronic Sleep Deprivation On Eating Behavior, Stephanie Frank
Effects Of Acute And Chronic Sleep Deprivation On Eating Behavior, Stephanie Frank
Lewis Honors College Capstone Collection
Sleep-deprivation is thought to be a factor in the rising American obesity epidemic. Altered sleep cycles affect appetite-regulating hormone levels and enhance the hedonic effect of food consumption. As a result, sleep restriction has been associated with an increased daily energy intake of more than 500 calories and high-carbohydrate/high-fat consumption. However, past studies have not examined the relationship between sleep deprivation and decreased intake of nutrient-dense fruits and vegetables as a factor in increased energy consumption. This paper aims to 1) determine the affect average hours of sleep or acute sleep deprivation (defined as less than 6 hour sleep per …
Evaluating Dietary Amino Acid Adequacy In Horses Using Isotopic Techniques, Sara L. Tanner
Evaluating Dietary Amino Acid Adequacy In Horses Using Isotopic Techniques, Sara L. Tanner
Theses and Dissertations--Animal and Food Sciences
Little is known about amino acid (AA) requirements in horses despite muscle mass accretion being of importance to an athletic species. Isotope methods for determining AA requirements and whole-body protein synthesis (WBPS) had not been previously used in growing horses. The first study herein was the first to apply isotope methods to determine WBPS in growing horses. In the study, weanling colts received two different levels of crude protein. Whole-body protein kinetics indicated that WBPS was greater when the weanlings were fed the diet with a greater crude protein content (P<0.05). The second study sought to determine a lysine requirement for yearling horses using the indicator AA oxidation (IAAO) method. Despite using six dietary levels of lysine; three above and three below the current recommendation, no breakpoint could be determined. Phenylalanine kinetics were not affected by lysine level (P>0.05), but plasma lysine increased linearly with lysine intake …
