Uses Of Genomic Predictions In Commercial Beef Cattle Operations, Matt Miller
Uses Of Genomic Predictions In Commercial Beef Cattle Operations, Matt Miller
Dairy Science
This paper aimed to achieve two different objectives. The first objective of this study was to identify and explain the genetic gain achieved in commercial beef cattle operations with the use of genomic predictions versus the use of visual appraisal and EPDs. The second goal of this paper was to develop a method to easily explain genomic predictions and their practical applications on commercial beef operations to a lay audience, specifically to ranchers. In order to accomplish these objectives, I evaluated three of the most common selection methods used by producers today. These included visual appraisal, expected progeny differences (EPDs), …

The Antimicrobial Activity Of Cold Pressed Terpeneless Valencia Orange Oil At Cold Temperatures, Sean Jeffrey Pendleton
Graduate Theses and Dissertations
This research was undertaken to identify an antimicrobial for use during chilling in beef processing, including periods of temperature abuse, as well as to evaluate membrane filtration as means to remove essential oils from bacteria to prevent further antibacterial action. Cold pressed terpeneless Valencia orange oil was examined in combination with various temperatures (37°C, 10°C, and 4°C) to determine its antimicrobial activity against various strains of bacteria. The strains were tested using a ninety-six well microtiter plate method, with or without membrane filtration. The compound 2, 3, 5-triphenyl tetrazolium chloride was used as a growth indicator. Serial, two fold dilutions …
