Factors Influencing Travel Order As Proxy For Leadership And Trade-Offs In Activity Budgets In Lactating And Nonlactating African Savanna Elephants, Malgorzata Wisniewska

Masters Theses & Specialist Projects

Nutritional and energetic needs of female mammals depend upon size or reproductive investment and shape individual activity budgets and behavioral patterns. To maximize nutritional and energetic intake females may increase time allocated to foraging or access resources through risk-prone behaviors, represented as aggression or leadership. Conversely, to minimize nutritional and energetic spending females may engage in risk-averse activities such as resting or nonaggressive social interactions. Females with the highest needs should exhibit activities and behaviors that facilitate the greatest nutritional and energetic returns or highest metabolic savings. The propensity for risk-prone behaviors may be greater among older as well as …

Executive Summary, Cumberland County Foodshed Assessment, Report 1, Barbara Ives

Local Food Systems

Like everyone else in these troubled economic times, Mainers are looking for ways to create jobs that will remain relevant and vital in a global economy, that cannot be outsourced, and that will regenerate rather than exploit our natural resources.

A growing number of people believe that a food system rooted in local farms, fisheries, and food production and distribution enterprises can strengthen Maine’s economy and its communities’ health, thereby increasing revenue and decreasing an expense that is crippling government agencies and individuals alike – healthcare. Business people who want to make a living related to food, and public and …

Estimation Of The Number Of Days Required To Determine Usual Antioxidant Intakes And Assessment Of The Prevalence Of Nutrient Inadequacy Among College Students, Catherine G. Davis

Master's Theses

High intake of antioxidant rich foods has been shown to decrease risk factors of chronic disease.  Young adulthood may be crucial in establishing healthy lifestyles including adequate nutrient consumption.

The present study was designed 1) to estimate usual nutrient intakes, 2) to calculate the number of days required to estimate usual antioxidant intake, and 3) to assess intake adequacy from diet and diet + supplement sources by using the Estimated Average Requirement (EAR).  The USDA Flavonoid and Proanthocyanidin databases, food consumption data, and dietary supplement use data from 60 students aged 18-25 years at the University of Connecticut were utilized. …

Intake, Apparent Digestibility, And Digesta Passage In Leopard Tortoises (Geochelone Pardalis) Fed A Complete, Extruded Feed, Laura Evelyn Lickel

Master's Theses

The influence of feeding juvenile female leopard tortoises (Geochelone pardalis, n=18) a commercially available, complete, extruded feed three (3) or seven days (7) per week on dry matter and digestible energy intake, apparent digestibility of dry matter, organic matter, gross energy and fiber fractions, animal body weight and measurements, digesta transit time, rate of passage, and indigestible fill was evaluated.  Both feeding frequencies are commonly practiced with captive tortoises. When fed 7 compared to 3 days per week, dry matter and digestible energy intake was greater.  Tortoises gained more g BW, but not when adjusted per kg initial …

Effect Of Brown Midrib Corn Silage And Dried Distillers Grains Plus Solubles On Lactational Performance And Nitrogen Utilization By Dairy Cows, Hugo A. Ramirez

Department of Animal Science: Dissertations, Theses, and Student Research

Thirty six Holstein cows, four ruminally cannulated, (mean ± SD, 111 ± 35 DIM; 664 ± 76.5 kg BW) were used in replicated 4×4 Latin squares to investigate the effects of brown midrib (bm3) and conventional (DP) corn silages, and the inclusion of dried distillers grains plus solubles (DDGS) on milk production and N utilization. In each 28 d period cows were assigned to one of four treatments: DP plus 0% DDGS (CON); bm3 plus 0% DDGS (BMR); DP corn silage plus 30% DDGS (DP+DG); and bm3 plus 30% DDGS (BMR+DG). Dry matter intake was greater (P < 0.01) for cows consuming bm3 (25.8 VS 24.4 ± 0.47 kg), likewise for DDGS (24.3 and 25.9 ± 0.47 kg/d for 0 and 30%). Compared to DP hybrid, NDFD was higher (P < 0.01) for bm3 (32.5 VS 38.1 ± 1.79%). There was a hybrid × DDGS interaction (P < 0.01) for total concentration of volatile fatty acids (VFA) and rumen pH as the highly digestible treatment BMR+DG resulted in the highest VFA and the lowest pH. Milk yield was not affected by treatment and averaged 30.6 ± 1.09 kg/d. Milk protein yield (MPY) was greater (P < 0.01) for bm3 and DDGS treatments. There was a hybrid by DDGS interaction (P = 0.02) for milk fat yield (MFY) resulting in 1.03, 1.08, 0.84 and 0.78 ± 0.045 kg/d for DP, BMR, DP+DG and BMR+DG. Fat corrected milk (FCM) was affected by DDGS (P < 0.01) and averaged 30.0 and 26.4 ± 1.0kg/d (0% and 30% inclusions). Urinary N excretion was similar among treatments; however fecal N was lower (P = 0.03) for diets containing bm3 corn silage which caused lower (P = 0.02) manure N. These results indicate that bm3 corn silage and DDGS increase DMI, NDFD and MPY; however high inclusion of corn silage with 30% DDGS reduces FCM. Nitrogen excretion was reduced when cows consumed bm3.

Feeding Corn Milling Co-Products To Feedlot Cattle, 3rd Edition, Galen E. Erickson, Crystal D. Buckner, Terry J. Klopfenstein

University of Nebraska-Lincoln Extension: Historical Materials

Introduction

Two primary types of milling processes currently exist, resulting in quite different feed products. These processing plants produce and market a variety of feed products, but in general, the dry milling process produces distillers grains plus solubles (DGS), and the wet milling process produces corn gluten feed (CGF). These feeds can be marketed as wet feeds, or they can be dried and marketed as either dry corn gluten feed (DCGF) or dry distillers grains (DDG) with or without solubles.

For the purposes of this report, wet corn gluten feed (WCGF), wet distillers grains plus solubles (WDGS), DCGF and dried …

Feeding Corn Milling Co-Products To Forage Fed Cattle, 1st Edition, Aaron Stalker, Rick Rasby, Galen E. Erickson, Crystal Buckner, Terry J. Klopfenstein

University of Nebraska-Lincoln Extension: Historical Materials

Introduction

Beef calves from weaning until they enter feedlots, developing heifers, and beef cows are fed primarily forage diets. Especially in the winter, forages are low in protein and phosphorus and need to be supplemented. Corn milling co-products are excellent sources of both protein and phosphorus and fi t nicely into winter supplementation programs. Corn milling co-products are also an excellent source of energy and are particularly well suited to forage based diets.

Two primary types of milling processes currently exist, resulting in quite diff erent feed products. The dry milling process produces distillers grains plus solubles (DGS), and the …

Interaction Between Roughages And Corn Milling Byproducts In Finishing Cattle Diets, Joshua R. Benton

Department of Animal Science: Dissertations, Theses, and Student Research

During ethanol production, starch is the primary nutrient fermented and the remaining byproducts are excellent sources of fiber and protein. In addition, inclusion of byproducts in finishing diets may reduce the incidence of acidosis. As a result, roughage level and quality could potentially be reduced in finishing diets containing byproducts. Three experiments were conducted to examine the effects of roughage and wet corn gluten feed (WCGF) in finishing cattle diets containing corn distillers grains plus solubles. Cattle fed finishing diets containing wet distillers grains plus solubles (WDGS) with no roughage had decreased DMI and ADG compared to cattle fed roughage. …

Influence Of Supplemental Legumes That Contain Tannins And Saponins On Intake And Diet Digestibility In Sheep Fed Grasses That Contain Alkaloids, Jacob Michael Owens

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

My objectives were to determine if nutritional benefits occur when animals are offered foods with compounds -- alkaloids, saponins, and tannins - that are potentially complementary. I hypothesized that food intake and digestibility increase when lambs consume plants such as alfalfa ALF that contain saponins or birdsfoot trefoil (BFT) that contain tannins when the basal diet is endophyte-infected tall fescue (TF) or reed canarygrass (RCG) both of which contain alkaloids. I predicted that the nutritional status of lambs would be enhanced if basal diets of alkaloid-containing grasses were supplemented with ALF or BFT.

Lambs fed a basal diet of either …
