Pig Production Environmental Footprint Calculator
The Pig Production Environmental Footprint Calculator (PPEFC) is a predictive swine farm model developed at the University of Arkansas in partnership with the National Pork Board. The PPEFC requires basic user inputs, such as barn dimensions and herd size, to estimate the productivity of a farm and its environmental resource requirements. It uses mathematical relationships to simulate growth, feed intake and water consumption, electricity and natural gas use, manure handling, and greenhouse gas emissions during each production cycle. Separate models can be created for sow and grow-finish barns. Depending on model input parameters, the grow barn model can simulate nursery, feeder- to-finish, or wean-to-finish barns.
Download Instructions
Step 1: Once you click the “Download the Calculator” button above, use the “save” feature to save the file to a folder on your computer; for example your “Downloads” folder. Please take note of where your file was downloaded so you can locate it for the next steps.
Step 2: After the download completes, find the file in the folder that you chose in the last step, and RIGHT CLICK on the file and select “Extract All” to extract the files from the Zip File. You will be able to choose the location where the files are extracted, but if you leave the default settings you will see a new folder labeled “PPEFC” in the same folder where your zip file is located.
Step 3: Open the PPEFC folder created in the last step, and click on the file titled “Pig Production Environmental Footprint Calculator” to run the application.
