Get the Most Economic Benefit From A Manure Digester

Get the Most Economic Benefit From A Manure Digester
Lambeau Field to host Midwest Manure Summit Feb. 15-16.

Bedding and co-feeding are two important factors that affect the economic sustainability of manure digesters on dairy farms according to Dr. Dana Kirk of Michigan State University and a speaker at the upcoming Midwest Manure Summit.

The type and quantity of bedding used on a dairy impacts biogas production and overall system performance. Many farms use digested manure solids as bedding thereby offsetting the cost of purchased bedding.  

Co-feeding organic waste streams from many industries has the potential to increase biogas production and add revenue by collecting "tipping fees."

Kirk notes that in addition to the performance impacts, decisions regarding the use of bedding materials and co-feeding should consider changes to manure management, permits and animal health. 

Kirk will discuss the economics of bedding and co-feeding at the Midwest Manure Summit to be held at Lambeau Field on Feb. 15-16 and sponsored by University of Wisconsin-Extension.

Make plans to join other dairy and livestock producers, government agency workers, agribusiness professionals, and educators as they take a closer look at the processing and handling of manure.
