Economies Of Size For Farrow-To-Finish Hog Production In Kansas (1993), Michael R. Langemeier, Ted C. Schroeder
Kansas Agricultural Experiment Station Research Reports
Economies of size measure the impact on average cost of production of increasing the size of operation. Data from 91 farrow-to-finish operations enrolled in the Kansas Farm Management Associations in 1992 were used to empirically estimate economies of size. Results indicate that average total cost and operation size are significantly correlated, and that average total cost declines as operations become larger. Results also indicate a substantial variability in costs of production between producers. In fact, costs of production between producers of a given size vary more than costs of production between operations of different sizes.; Swine Day, Manhattan, KS, November …

Evaluation Of Carcass Merit Pricing By Pork Packers (1993), Ted C. Schroeder
Evaluation Of Carcass Merit Pricing By Pork Packers (1993), Ted C. Schroeder
Kansas Agricultural Experiment Station Research Reports
Live hog prices must reflect end-use value to convey market information from consumers to producers. Precise end-use value is excessively costly to trace for each carcass given current technology. Pricing structures must be based upon carcass merit information that is correlated with end-use value. This study uses pork carcass cut out data from 794 carcasses to estimate hog carcass values based upon carcass characteristics. Carcass values varied by nearly $20/cwt based on quality differences alone. In addition, considerable differences were present in pricing schedules of different pork packers suggesting that hog producers need to shop around when deciding to which …
