Economics of Weaning Age Calculator Microsoft Excel spreadsheet
This calculator can help producers evaluate whether it pays to reduce breeding herd inventory in order to increase weaning age. It also can help producers determine how much the breeding herd inventory must change for alternative weaning ages to ensure that the farrowing capacity of the farm is not exceeded. Developed by Derald Holtkamp, ISU.
Excel 2003 version
Excel 2007 version

Genomic Selection Spreadsheet Microsoft Excel spreadsheet
This spreadsheet can be used to estimate the total costs associated with genome-enabled selection. Producers can see how much improvement in a weaned pig will be necessary in order to break even on the costs associated with genome-enabled selection, and to determine if they think investing in animals that have been selected based on genomic methods is economically viable. Seedstock suppliers can use the spreadsheet to make breeding program decisions. Register for this free download.
Developed by Ken Stalder and Caitlyn Abell, ISU.

Sow Longevity Spreadsheet v2  Microsoft Excel spreadsheet
This spreadsheet can help producers determine optimum times for keeping sows in their operations. It uses operation-specific production and financial information, so individual producers can determine how long sows must remain in their herds to create a positive net value. Developed by Ken Stalder, ISU, and Curt Lacey, University of Georgia.
