How Weather Affects Total Mixed Rations And Why It Is Significant To Dairy Cattle, Juliana Baranowski

Honors College

The objective of this study was to determine how weather affects the dry matter percentage of a TMR fed to dairy cattle. Daily feed samples were collected from the University of Maine’s J.F. Witter Teaching and Research Center and stored in a freezer until dry matters could be determined. The feed samples were later thawed out, then placed in an oven at 60oC for a minimum of three days. This allowed all the moisture to be evaporated so the DM could be calculated. The maximum, minimum and average temperatures, as well as the precipitation and humidity were obtained daily from …

Envisioning A Bold Food Waste Policy For Maine: A Mixed-Methods Study Into The Context Of Landfill Diversion Of Food Waste, Dominique Danielle Dispirito

Honors College

Landfilled organics waste both natural and financial resources by discarding usable materials that could bolster food security programs and composting efforts. According to the Drawdown Project, one-third of the food we produce in the United States goes to the landfill without ever reaching someone’s plate, contributing to leachate at disposal sites and accounting for more greenhouse gasses than the entire airline industry. As communities across the state struggle to support the 1 in 6 Mainers experiencing food insecurity with dwindling financial resources and limited personnel, food waste diversion provides a local solution that bolsters resilience at low cost. The absence …

The Potential Use Of Tree Leaf Silage For Livestock Nutrition, Including Willow, Drumstick, Mulberry, And Acadia Species, Jade Chin

Honors College

Leaf silage has been historically used as ruminant feed, with multiple positive attributes such as being a secure, preserved feed source that is relatively accessible. However, the digestibility, nutritive value, and potential anti-nutritive factors are not well researched or known. The goal of this review is to examine recent literature on leaf silage and its potential advantages and practical limits of being utilized as livestock feed. The scope of this study was limited to willow (Salix spp.), acacia (Acacia spp.), mulberry (Morus alba and Broussonetia papyrifera), and drumstick leaf silage (Moringa oleifera), due to …

Scientific Knowledge Shaping Perceptions Of Bioengineered Food Among Undergraduate Students, Kathleen Tims

Honors College

While commonplace in our grocery stores, GMO-foods have persevered through years of controversy. As the availability of bioengineered(BE) commodities grows and biotechnical industries make strides, studies have shown that the average consumers’ knowledge concerning biotechnology has not. In addition to widely held misconceptions and the general lack of knowledge regarding bioengineered commodities reported by young adults, especially students, the recent United States Department of Agriculture mandate for BE product labeling prompts further research into the consumer perspective on bioengineered products. This research looked to expand upon prior work regarding students’ individual perspective towards topics such as GMOs, knowledge of BE …

Exploring The Nutritional Value Of Carrots And Determining Attributes That Are Favored By Consumers, Hannah Harling Stefl

Honors College

This study explored 24 varieties of carrots, the most popular vegetable of the Apiaceae family. Carrots are one of the most widely consumed vegetables. They are a cool season vegetable crop, which comes in many different varieties and colors, each having its distinct aroma, content of volatiles and nutritional compounds that influence the harshness or eating quality of the carrot. In the US, 3.5 billion pounds of carrots are grown each year, showing the importance that carrots have in United States agricultural economic systems. Carrots are an important vegetable due to their characteristic flavor and the many health benefits, such …

Using The Real Food Calculator To Assess The University Of Maine's Dining Purchases Within A Food System Context, Ashely Thibeault

Honors College

This study investigated the University of Maine’s food purchasing using the Real Food Calculator to determine the Real Food percentage. Real Food is defined by the Real Food Challenge as local, humane, fair, and ecologically sound. The Real Food Challenge is an organization that seeks to create systemic food system change through student efforts on college campuses by shifting food purchasing to 20% Real Food by 2020. The University of Maine had 5% Real Food in the 2012-2013 academic year. While there are limitations to Real Food and the Real Food Calculator, it may produce a change in the food …

The University Of Maine Food And Fitness Environment: Is It Health Promoting?, Carolyn Anne Stocker

Honors College

Obesity impacts one in six young adults, ages 20-29, and is a major risk factor for chronic disease. An environmental audit of the University of Maine campus was conducted to identify supports for healthful lifestyles by assessing the vending, dining, and recreation environments. Instruments developed by a multistate research team were used to determine scores and percentages for the audit. Ten buildings were assessed in the vending assessment. The mean healthful snack percentage was 17% and the mean healthful beverage percentage was 18% of total items. Two on-campus and seven off- campus dining establishments were assessed. The on-campus dining establishments …

Worksite Wellness For Umaine Dining Employees: Healthful Eating For The Holidays, Marissa E. Rublee

Honors College

The objective of this study was to identify change in knowledge and intent to

change behavior among University of Maine dining services employees (n=5 females) attending a three-session nutrition education program. The study was a one-group design with a pre- post- assessment. Participants were recruited through flyers distributed at their worksite. The intervention consisted of three one-hour nutrition education sessions implemented outside work hours one day per week over three weeks. Sessions were designed to address healthful holiday cooking and eating, with a focus on 100% whole grains. At pre-assessment, based on a five-point scale from 1= “not likely at …

The Ability Of Berry Extracts To Inhibit Alpha-Glucosidase In Vitro, Shannon Dubois

Honors College

Type 2 diabetes is a growing public health concern. Drugs, such as acarbose, are used to slow the rise in blood glucose levels after meals by inhibiting the enzyme, alphaglucosidase, which is responsible for digesting complex carbohydrates. The objective of this study is to compare the alpha-glucosidase inhibitory activity of extracts from Maine blueberries and blackberries to acarbose because these plants are very anthocyanin-rich. Varietal differences in highbush blueberries (Vaccinium corymbosum) and agricultural practices for growing wild or lowbush blueberries (Vaccinium angustifolium Ait.) are also experimental variables. The twelve berry samples were obtained from farms around the state of Maine …

A Study Of Cooking And Varietal Effects On Potato In Vitro Bile Acid Binding Capacity, Emily Hinkle

Honors College

Potatoes have received negative press about being unhealthy due to having high starch content, but these vegetables contain many healthful components. Many compounds in food, such as soluble dietary fiber, help reduce serum cholesterol levels by binding to bile acids in the digestive tract and causing the body to draw from serum cholesterol to create new bile acids. Potatoes were prepared three different ways (raw, steamed, steamed then cooled) and different varieties of potatoes were used, each with different chemical compositions (King Harry, Elba, Yukon Gold and All-Blue). The potatoes were subjected to an in vitro digestion to simulate the …

Slow Food: From Farm To Healthy Body, Hannah L. Ruhl

Honors College

Slow Food is a movement devoted to the preservation and promotion of personal, environmental and community health through lifestyle changes which focus on good, clean and fair food. Good refers to food that is healthy and nutritious for the body. Food grown sustainably as in organic agriculture contains higher levels of beneficial compounds such as vitamins, minerals and phytochemicals. Clean food contains no toxic or harmful compounds that can cause detrimental effects on health. Pesticides and other chemicals are often used in food production; as a result they are found in the final product and are often detected in the …
