PEDV and Manure Hauling

The National Pork Board has recently released new research reports on PEDV.  You can find a summary of this research and links to other resources on PED on the "Hot Topics" page of the IMMAG web site. In conclusion, it is still prudent to be careful when sequencing pit pumping crews in the fall of 2014.

  • As before (with diseases such as PRRS), clean sites should be pumped first, followed by barns that have had the longest amounts of time post PEDV infection and then working towards the barns that have had less amount of time post infection.
  • Communication with neighboring swine farms is crucial, especially when manure has to be applied near to their sites.


Fall application season is rapidly approaching.  Be sure your annual training requirements are up to date prior to applying manure.  You can contact your County Extension Office to determine dates available for training, or you can call you local DNR Field Office to schedule an appointment to take the certification exam.

A reminder to COMMERCIAL manure applicators: A new employee can work for a licensed commercial applicator business for the first 30 days of employment without meeting the certification requirement as long as a certified commercial manure applicator is physically present at the site and must be in sight or immediate communication with the new employee at all times. After 30 days, new employees must be meet certification requirements. The 30-day exemption is only valid once and does not apply each time the employee is rehired. 
Certification requirement for employees of commercial manure services (businesses) is not valid unless the business is certified.


The IMMAG Events page is a compilation of manure management related events. Please check the events page often for new listings.

There are 4 manure tours this week. The ISU Dairy Team is hosting a series of manure handling and nutrient management field days throughout October as part of a Risk Management Grant looking to help farmers manage both profitability and environmental risk. This is a great opportunity to see a wide-variety of dairy manure handling systems on a variety of farms. The list of field days can be found on the IMMAG web page or at this link.
