Study Of Three Potential Variables That May Impact The Maximum Shear Force And Shear Variation During The Growth And Transport Of Mixed Sex Broilers Grown In Commercial Poultry Houses, Mark Christie

Graduate Theses and Dissertations

Temperature conditions during the transportation to the processing facility of commercial broilers have a direct impact on the meat texture, specifically maximum shear force and shear variation of cooked breast meat. Analysis of a calendar year of flock data (N=346), reveals that the largest impact of transport conditions, specifically temperature, is on the standard deviation of the flocks range of cooked shear values. The optimal transport temperature that yields broiler breast meat with average flock minimum shear and standard deviation values is approximately 60°F. The shear values for flocks at or near 60°F are on average 1 kg less than …

The Influence Of Family Cohesion And Relationship Maintenance Strategies On Stress During Students’ Adjustment To College, Claire C. Strutzenberg

Graduate Theses and Dissertations

This study examined the effects of family cohesion and relationship maintenance behaviors on students’ experience of stress during the adjustment to college. One hundred and ninety-eight first-year college students completed measures assessing family cohesion; relationship maintenance behaviors expressed within their family systems; and academic, social, and personal-emotional stress. Results indicated that family cohesion is significantly and negatively related to students’ experiences of academic, social, and personal-emotional stress. Further, hierarchical regression and structural equation modeling provided insight to the additive influence of relationship maintenance behaviors on student stress. Analyses provided limited support for a mediation model, however, results demonstrated the importance …

The Impact Of A Learning Community On The Perceived Wellness Of First Year Doctor Of Physical Therapy Students, Angela Mae Holland

Graduate Theses and Dissertations

Healthcare education guides students in obtaining skills to promote health in others. In working towards this goal, graduate students in healthcare programs potentially suffer from increased stress while undergoing the rigor of a medically based academic program. The purpose of this study was to determine if the addition of a learning community program had an effect on the perceived wellness of first year doctor of physical therapy students. A repeated measures quasi-experimental design was used to answer the three research questions, which guided the investigation. Three groups of participants completed the study, one serving as the experimental group with the …

Genomic Approaches To Identify Important Traits In Avian Species, Bhuwan Khatri

Graduate Theses and Dissertations

This dissertation focusses on identifying different molecular markers that have impact on overall poultry production. Chapter one reviews microRNA (miRNA), copy number variation (CNV) and single nucleotide polymorphism (SNP) as markers suggested in different avian species by various studies. It reviews modern genomic approaches that are employed for next generation sequencing data analysis and verification.

Chapter two seeks to identify and validate the muscle specific miRNAs in the breast muscle of modern broilers and its foundational chicken line. Small RNA sequencing was performed to identify differentially expressed mature miRNAs in the breast muscles of these two chicken lines. Results showed …
