Evaluation Of L-Methionine Bioavailability In Nursery Pigs, Jina Lim

Theses and Dissertations--Animal and Food Sciences

DL-Methionine (Met) has been conventionally used in swine diets with assumption of similar bioefficacy with L-Met. However, because L-Met is the form that is utilized by animals for protein synthesis, L-Met could, theoretically, be more available. Four experiments were conducted to evaluate L-Met bioavailability in nursery pigs with 21-day growth trials. A total of 105,105,112 and 84 crossbred pigs were used in Exp. 1, 2, 3 and 4, respectively. Each experiment had a low Met basal diet and 3 levels of the Met sources (DL-Met and L-Met). In addition to the basal diet, supplementation levels were 0.053%, 0.107% and 0.160% …

Mediation And Moderation Analysis Of Nutrition, Inflammatory Biomarkers, And Cognition In Older Adults, Elizabeth Handing

USF Tampa Graduate Theses and Dissertations

Nutrition can be viewed as a modifiable factor related to maintaining and preserving health in older adults. Previous studies have found that nutritional factors can influence cognitive abilities, however few studies have examined macronutrients and micronutrients as they relate to cognitive functioning. Research has yet to examine the mechanisms related to nutrition, cognition and aging in an older adult population from a holistic and interactive perspective.

This dissertation examined three research questions to better understand the relationship between age, nutrition, cognition, and inflammatory biomarkers. First, is nutrition related to cognition beyond demographic factors? Do individual nutrients serve as mediators? Second, …

Effects Of Post-Hatch Holding Time And Early Nutrition Strategies On Growth Performance, Carcass And Skeletal Characteristics Of Young Chickens, Marquisha A. Paul

Theses and Dissertations--Animal and Food Sciences

The study objectives of this thesis were to evaluate the effects of delayed feeding and specific aspects of the Programmed Nutrition (PN) feeding strategy (Alltech, Inc.) on growth performance, carcass characteristics, and skeletal characteristics of commercial broiler chicks through market age, as well as investigate the effects of breed and the PN feeding strategy on early growth and development. When commercial broiler chicks were fed reduced nutrient diets, delayed feeding decreased early growth performance and carcass yield (P<0.05), whereas post-hatch PN conditioning for 72 hours improved early growth performance and alleviated the negative effects of delayed feeding on carcass yield (P<0.05). Through market age, delayed feeding improved Gain: Feed (P<0.05), while PN had the opposite effect. Interactive effects and main effects of delayed feeding and PN were observed for tissue mineral concentration (P<0.05). PN lowered bone ash % (P<0.05) and increased meat oxidation of broiler chicks during storage (P<0.05). PN also had negative effects on early growth performance and bone breaking strength (P<0.05) of various meat-type breeds, but especially for non-commercial, moderate-growing or fast-growing breeds. In conclusion, PN may be suitable for commercial broiler chicks that experience delayed feeding and are fed reduced nutrient diets.

Parental Attitudes, Concerns, Health & Knowledge Of Nutrition And Their Relationship To Usage Of Functional Foods In Parental Feeding, Lauren Elizabeth Guy

Electronic Theses and Dissertations

The purchase and consumption of functional foods is one of the fastest growing trends in the food and nutrition industry. Though many studies have suggested reasons why consumers purchase and consume functional foods, there has been limited research to understand what factors, if any, influence the use of functional foods in parental dietary practices. Therefore, the purpose of this study was to determine whether parental awareness of functional foods, self-reported knowledge of nutrition, overall health, and concern for their children's diets play a role in the provision of specific categories of functional foods (digestive health, weight management, bone health, cancer …

Desensitization Of Hacat Keratinocytes To Vitamin D3 Occurs Via Loss Of Redd1 Regulation Of The Mtor Pathway, Michelle Leigh Jones

Wayne State University Theses

Vitamin D3 treatment has long been considered in the treatment of cancer due to its well-documented anti-proliferative effects in vitro. While clinical studies have been positive in other cancers, results are inconclusive in cases of basal cell carcinoma. To better understand the reasons underlying this disconnect, this study employs an immortalized human keratinocyte cell line (HaCaT) to observe the effects of vitamin D3 treatment on cellular proliferation. The results show that both activate vitamin D3 (calcitriol) and its precursor (cholecalciferol) increase proliferation of these cells. Real-time PCR and western blot data indicate that the mTOR pathway becomes activated despite increased …
