  • Patent number: 10028490
    Abstract: An integrated system of technology applications and methods to provide comprehensive management of poultry waste improves the productivity of poultry housing facilities while reducing the environmental and public health impacts of poultry production. The method utilizes a plurality of housing units, each including plenum flooring and ventilation to improve the health of birds as they grow from hatchlings to market size adults. After the birds are removed from the housing units, manure is immediately removed from the flooring system and preferably transported to a processing facility. The units are cleaned and fumigated with ozone so that they are ready to receive a new flock within approximately 48 hours from removal of the preceding flock.
