Investigation Of Breeding Objectives And Indexes-In-Retrospect, Hunter F. Valasek
Investigation Of Breeding Objectives And Indexes-In-Retrospect, Hunter F. Valasek
Department of Animal Science: Dissertations, Theses, and Student Research
This thesis presents two projects that investigate the impacts of breeding objectives and indexes-in-retrospect within the beef cattle industry. The first project synthesized how changes due to planning horizon, breeding system, and sale endpoint in the economic breeding goal of cattle influence the relative emphasis of traits as well as the re-ranking of selection candidates. A total of three breeding systems that represent straightbred and crossbred cattle were used along with six planning horizons (2, 5, 10, 20, 30, and 50 yrs.) for both a weaning and slaughter point of sale. The combination of these different breeding objective attributes resulted …
A Forecasting-Programming Method For Placement-Sales Decisions For A Beef Feedlot, Franz Schwarz, J. B. Hassler
A Forecasting-Programming Method For Placement-Sales Decisions For A Beef Feedlot, Franz Schwarz, J. B. Hassler
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
This bulletin reports on a practical multi-period linear programming procedure as a management tool for decisions on placements and marketings for a beef feedlot operating over time under market uncertainty. Although the conclusions were based on application to an individual firm with uniqueness in time and space, the model should be equally appropriate for any firm's production and marketing decisions through time.
