Effects Of Enzymatically Hydrolyzed Yeast Supplementation And Supplementation Frequency On Immune Parameters, Performance, And Digestibility Among Periparturient Beef Cows And Calves, Janine Swartz Jan 2018

Effects Of Enzymatically Hydrolyzed Yeast Supplementation And Supplementation Frequency On Immune Parameters, Performance, And Digestibility Among Periparturient Beef Cows And Calves, Janine Swartz

Electronic Theses and Dissertations

Effects of enzymatically hydrolyzed yeast (EHY) and supplementation frequency (FREQ) on immune parameters among beef cows and calves was evaluated. Eighty multiparous (parity = 4.2 ± 0.3) cows were fed a common brome hay-based diet (CP = 8.0 ± 0.17%). Cows were blocked by expected calving date and stratified by body condition score (BCS) before random assignment of treatment. Beginning 88 ± 5 d prior to parturition, cows were provided 1 kg daily or 3 kg every 3 d of a soybean hull-based supplement (CP = 34.0, % of DM) that contained 0 or 3 g/kg EHY. The daily supplement …


Influencing Food Choice: Effects Of Stress And Sleep Deprivation On Dietary Habits Of Young Adults, Amy L. Leiferman Jan 2017

Influencing Food Choice: Effects Of Stress And Sleep Deprivation On Dietary Habits Of Young Adults, Amy L. Leiferman

The Journal of Undergraduate Research

Introduction: Lifelong dietary habits are shaped during young adulthood; hence, preventing poor food choice practices during this period is vital. Stress and sleep deprivation are two important lifestyle elements that affect eating habits. The purpose of this study was to evaluate stress and sleep deprivation as factors contributing to poor dietary choices of college-aged students. Methodology: During finals week, a survey inquiring about sleep duration, perceived stress, and dietary patterns throughout the semester (typical week vs. finals week), was administered to university students (n=83). Fifty-five participants (21 male) provided an ID number, which allowed university-collected demographic and food-purchasing …


Relationship Of Stress, Sleep, Physical Activity, And Food Insecurity On Eating Behaviors And Obesity, Amy Lee Richards Jan 2017

Relationship Of Stress, Sleep, Physical Activity, And Food Insecurity On Eating Behaviors And Obesity, Amy Lee Richards

Electronic Theses and Dissertations

There is an urgent need to find effective interventions to prevent and reduce obesity as it is associated with chronic disease and decreased quality of life. Gaining a better understanding of how modifiable variables such as stress, sleep, physical activity, and food insecurity are related to eating behaviors associated with obesity is essential to guide the direction of future interventions and research. Interventions that hold promise need to be tested to determine if they have merit or not. This dissertation presents three papers. Two papers are cross-sectional studies evaluating associations between eating behaviors, obesity, and modifiable variables (stress, sleep, physical …
