Evaluating The Relationship Between Ultrasound-Derived Carcass Characteristics And Production Traits In Angus Cattle, William Michael Mayfield Aug 2012

Evaluating The Relationship Between Ultrasound-Derived Carcass Characteristics And Production Traits In Angus Cattle, William Michael Mayfield

Masters Theses

Profitability in the beef industry is a crucial aspect of management schemes. The overall aim of this study was to determine if carcass ultrasonography in replacement heifers could explain variation in traits such as reproduction, a major factor in beef cattle efficiency and profitability. During a 10-year period, data were obtained from 906 yearling heifers through the use of carcass ultrasonography. The measurements collected included adjusted values for ribeye area (REA), percent intramuscular fat (%IMF), rib fat (RF), and rump fat. A retrospective analysis was performed on data collected and variables were separated into the extreme high and low 25% …


Northern Bobwhite (Colinus Virginianus) Population Ecology On Reclaimed Mined Lands, Evan Philip Tanner Aug 2012

Northern Bobwhite (Colinus Virginianus) Population Ecology On Reclaimed Mined Lands, Evan Philip Tanner

Masters Theses

The northern bobwhite (Colinus virginianus) has experienced range-wide population declines for the past half century. The primary cause has been large-scale habitat loss and fragmentation. Through auspices of the Surface Mining Control and Reclamation Act of 1977 (SMCRA), large tracts of early successional vegetation have been created throughout much of the bobwhite’s range that may be managed to increase usable space. Peabody WMA is a reclaimed coal mine in Western Kentucky where bobwhite have been present in the past. To better understand the dynamics of this population and how habitat on Peabody WMA influences these dynamics, my two …


Economic And Environmental Effects Of Switchgrass Production On A Representative Cow-Calf Farm In Middle Tennessee, Hanna Leah Watts May 2012

Economic And Environmental Effects Of Switchgrass Production On A Representative Cow-Calf Farm In Middle Tennessee, Hanna Leah Watts

Masters Theses

The purpose of this research was to evaluate the economic tradeoffs and land use dynamics of incorporating switchgrass into the farm plan of a representative middle Tennessee cow-calf operation. A net revenue simulation and multi-year mathematical programming model was used to find the optimum mix of switchgrass and cow-calf enterprises that will maximize whole farm net revenues over 30 years on a representative middle Tennessee beef farm under both average and above average management. Land use changes predicted by the mathematical programming model were used to assess the carbon change associated with incorporating, or transitioning to, switchgrass production.
