A process includes microbially degrading harvested polyculture plant material to form a concentrated microbial biomass and providing the concentrated microbial biomass to an intermediary animal for consumption. The process may also be directed to producing a product animal which includes providing a growth area having an outlet for waste and providing a harvested plant material collection area having an outlet for degradation products. The process may also include providing a microbial growth system for producing a bacterial biomass and directing at least some waste from the outlet of the product animal growth area to the harvested plant material collection area. The process may also include directing at least some degradation products to the microbial growth system, directing some of the microbial biomass produced in the microbial growth system to an intermediary animal for consumption, and directing the intermediary animal to a product animal growth area.
