Effect Of Varying Rumen Degradable And Undegradable Protein On Milk Production And Nitrogen Efficiency In Lactating Dairy Cows Under Summer Conditions, Jeffrey D. Kaufman

Masters Theses

The objective is to determine the effect of reducing nitrogen input through feeding low rumen degradable protein (RDP) and rumen undegradable protein (RUP) proportions on milk production, nitrogen efficiency and metabolism in heat-stressed cows. Forty-eight mid-lactating, Holstein cows were assigned to treatments using a randomized block design in a 2x2 factorial arrangement of treatments (n = 12/treatment). Treatments included two levels of RDP (10 and 8%) and two levels of RUP (8 and 6%). From d 1 to 21, a common diet (10% RDP-8% RUP) was fed to cows followed with their respective treatment diets fed from d 22 to …

Beneficial Effects Of Naringenin And Indomethacin On White And Brown Adipocytes, Jamie Ann Kearns

Masters Theses

As obesity continues to grow and medical costs in the United States are estimated at $147 billion annually, novel ways to prevent and treat obesity are needed. One approach is to promote thermogenesis to improve energy balance by increasing the activities of thermogenic brown and beige adipocytes.

Naringenin, a citrus flavanone, has been shown to act as anti-inflammatory and lipid lowering agent as well as activate PPARgamma. However, it is unclear whether it can activate thermogenic activity in white adipocytes, i.e., promote formation of beige adipocytes. Indomethacin (INDO) is an FDA approved drug used to treat pain related to inflammation …

Utilizing Nutritive Sweeteners To Control Lipid Oxidation In Low Moisture Baked Goods, Samantha Vieira

Masters Theses

In this study, we determined the effect of nutritive sweeteners at 0 to 0.50 moles/kg on lipid oxidation in a model cookie system. Confocal microscopy using Bodipy 493 as a fat soluble dye showed that the fat formed a continuous phase surrounding the starch granules regardless of sugar type. The impact of glucose concentration on lipid oxidation was monitored by lipid hydroperoxides and headspace hexanal during storage at 55°C. Low concentrations of glucose (0.09) were strong inhibitors. At equal molar concentrations, reducing sugars (glucose and fructose) inhibited lipid oxidation, greater than a two months increase in lag phase compared to …

An Online Study Of Undergraduates' Knowledge, Awareness, And Attitudes Of Preconception Care, Kelly Jean Crusenberry

Masters Theses

Background: The majority of pregnancies in the United States are unplanned. Health status and health-related behaviors such as poor nutrition, alcohol consumption, and/or tobacco use, occurring prior to conception, have been linked to poor obstetric outcomes for mothers and their offspring, many of which can result in lifelong challenges. Knowledge, awareness, and attitudes can be predictors of health-related behaviors, and preconception care and education may reduce risk of some of these poor obstetric outcomes. Undergraduate students are at an increased risk for many of these risky behaviors and for unplanned pregnancies, as compared to older individuals. However, little is known …

Farm-To-Preschool In East Tennessee: Evaluation Of A Small-Scale Farmer’S Market At A Childcare Center On Household Fruit And Vegetable Availability And Preschoolers’ Consumption Of Fruits And Vegetables, Jade Morgan Parry

Masters Theses

Background: Most preschool-aged children do not consume an adequate amount of fruits and vegetables (F&V). Accessibility to F&V and parental influence are important factors in determining fruit and vegetable consumption in preschool-aged children. The incorporation of farmer’s markets at childcare centers as part of a farm-to-preschool program provides an opportunity to increase access to F&V and engage parents in supporting positive changes in their children’s dietary behaviors. Gaps in the farm-to-preschool literature include a lack of well-designed intervention trials that include a control group and rigorous evaluation tools.

Methods: This was a pilot study with a quasi-experimental, pre-test, post-test …

Fruit And Vegetable Intake, Attitudes, And Beliefs Of Multicultural Middle School Students In Central Massachusetts, Emily M. Harrington

Masters Theses

High fruit and vegetable (FV) intake is associated with healthy weights and decreased risk of chronic disease. Yet, adolescent FV intakes fall below national recommendations. Few studies involve racial/ethnic minority adolescents in formative research, despite their increased risk of poor FV intake. Consequently, the purpose of this study was to describe the type and frequency of FV intake of urban multicultural young adolescents, and to examine their attitudes and beliefs towards increased consumption of FV. A convenience sample (n=79) of racially diverse (e.g., 31% Hispanic/Latino, 27.4% Black/African American) grade seven students, participated in our study comprised of a self-administered survey …
