Feb 12, 2021 Pork producers can learn more about building ventilation from the inside out through a series of workshops in mid-March. Iowa Pork Industry Center joins Iowa State University Extension and Outreach in offering "Managing Your Unseen Employee: The Ventilation System" at five different Iowa locations at no cost. The series is sponsored by Automated Production Systems (AP) and lunch is provided courtesy of Iowa Pork Producers Association. Brett Ramirez of ISU agricultural and biosystems engineering said the daylong program provides a two-pronged approach to understanding issues and consequences of decisions by combining classroom instruction with hands-on trials and application of knowledge gained in a real-world setting.
