Does hog size impact manure production?

Daniel Andersen, aka Dr. Manure, addresses a multi-part question about the proper facility design and size to adequately handle the manure produced in a swine operation in a late-April blog. Andersen is an assistant professor in the Iowa State University Agricultural and Biosystems Engineering Department.

He had received the question “why are more swine farmers hauling in spring and fall, why is this occurring, and what is a good number to use for sizing your manure storage?”

He explained that though the answer seemed easy on the surface, but he went onto answer a follow-up question posed, asking how all of this is impacted by feeding hogs to a higher finished weight, say 285 to 315 pounds.
