Use to determine optimal breeding and farrowing dates based on individual operations and inputs. Developed by Ken Stalder and Garland Dahlke, Iowa State University. Cost is $50 per copy. 

This tool helps the producer determine the optimum maximum culling parity for commercial sow herds by estimating the economic value for the genetic improvement that occurs over time (also known as genetic lag.) Developed by Ken Stalder and Caitlyn Abell, Iowa State University.

This spreadsheet estimates 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. Developed by Ken Stalder and Caitlyn Abell, Iowa State University.

This spreadsheet is utilized to determine optimum time for keeping sows. It uses operation-specific production and financial information, so producers can determine how long sows must remain in the herd to generate a positive net value. Developed by Ken Stalder, Iowa State University, and Curt Lacey, University of Georgia. Also available: English, Metric measurement, Chinese, Metric measurement, Portuguese, Metric measurement, Spanish, Metric measurement

Allows producers to vary input and operational costs to see how differing scenarios affect their operation’s economic bottom line. Developed by John Mabry, Colin Johnson and Garland Dahlke, ISU. Cost is $20 per copy.

Use to help evaluate a current or potential swine producing scenario in terms of both budget and cash flow for a period of up to 11 years. Developed by Ken Stalder and Garland Dahlke, Iowa State University. Cost is $50 per copy.

This calculator can help producers evaluate if it pays to reduce breeding herd inventory, in order to increase weaning age. Determine how much the breeding herd inventory must change for alternative weaning ages, to ensure farrowing capacity of the farm is not exceeded. Developed by Derald Holtkamp, Iowa State University.

Estimate the margin of return for cattle or hogs placed on feed at a user defined date. Chicago Mercantile Exchange futures data are used. Corn and soybean meal are used to generate the margin. The margin provides an estimate of gross return that will need to cover the other costs and profit goals.

Use this decision tool to evaluate the added return per head from marketing hogs a few days later and at a heavier weight.

Use this decision tool for help in evaluating optimal marketing weight.

University of Minnesota, Odor From Feedlots Setback Estimation Tool (OFFSET) Based on Minnesota climatic conditions. OFFSET user guide and worksheet

University of Minnesota tool provides estimates of the economic value of manure based on manure type, application method, soil nutrient status and crop need.

Compares manure nutrient values to commercial fertilizer. Developed by Kelvin Leibold and Tom Olson, Iowa State University.

Includes P-index information for Iowa producers. Developed by Ken Stalder and Garland Dahlke, Iowa State University.

Calculate results from feed uniformity testing. Enable macros for correct calculations. Developed by Mark Storlie, Iowa State University.

Helps determine the optimal use of distillers dried grain in finishing pig rations to maximize economic return. 

This tool can help producers extend on-hand feed supply by restricting feeding group housed pigs. This tool can be used as a guide to estimate daily pen feed allowance utilizing two input factors. 

Allows for consistent collection of data for comparison within an operation and between aggregated group data. The program creates a closeout summary for individual finishing pig groups and calculates all performance and production parameters using the NPPC Standards. Developed by Mark Storlie, Iowa State University. Cost: In Iowa -- $30 with data sharing, $100 without sharing; outside Iowa -- $50 with data sharing, $150 without sharing.

This tool will help pork producers provide an adequate number of grow-out spaces for weaned pigs, ensuring production standards are met year-round. Developed by Ken Stalder and Garland Dahlke, Iowa State University.

Graphs daily water disappearance as a measure of the growth process for groups of pigs. Developed by Mark Storlie and Mike Brumm.
