One swine barn with 2,400 feeder pigs generates as much manure as a town with 7,000 people. Dodge County has a human population of approximately 21,000 or the manure equivalent of swine barns holding about 7,200 feeder pigs.
Swine held in Confined Animal Feeding Operations ("CAFOs") are owned by corporations and not by the local operator. These corporations get most of the profits, and we have to deal with all the manure.
