Steve Pohl:Helping pork producers understand the basics of ventilating hog barns

摘要

Swine building designs evolve over time, and with those changes come a whole new set of rules in environmental management. But one thing producers need to remember is that despite those structural changes, the basic rules for proper ventilation neverchange, observes 61-year-old Steve Pohl.To help spread the word on swine building ventilation, Extension agricultural engineer Pohl from South Dakota State University (SDSU) at Brookings, joined by a cast of engineers and animal scientists from Iowa, Minnesota and Nebraska, including swine consultant Mike Brumm, have taken the show on the road. Ten traveling workshops have been conducted around the Upper Midwest with a fully equipped mobile ventilation trailer.Through his 25 years at SDSU, understanding the basics of ventilation have become virtually a campaign for the soft-spoken Pohl, who becomes highly charged as he attempts to explain the intricacies of air movement through swine barns.
