The topic of an Aug. 20 PorkCast webinar is Emergency Ventilation and Properly Ventilating Barns when Emptying Manure Storage Pits. The webinar is from 1-2 p.m. and there is no cost to take part.

The process of preparing to empty manure pits and apply manure to fields this fall raises concerns for the welfare of people and pigs. Producers must ensure pit-pumping procedures provide adequate ventilation. Ideally, barns are empty when agitating and pumping pits, but in most cases, this is not practical.

Mike Brumm of Brumm Swine Consultancy, Inc., North Mankato, MN, will address barn and ventilation management practices that can significantly reduce worker risk and animal asphyxiation.
