A system for maintaining and feeding animals in a confined environment wherein a structure is provided having a plurality of tiers with each tier being partitioned into a plurality of animal confinement pans. The floors of each pen are of an open grillwork to allow a controlled flow of ambient ventilation air to flow upwardly through the pen and into the pen in the tiers above, and a portion of each pen is set aside to collect the animals'excrement. The collected animal excrement is flushed by a flowing water system into a collecting trough and returned to a central collecting trench where it is processed by promoting a bacteria and fungi action to convert the animal waste into a useable protein supplement which is added to the animals'food supply. The supply, i.e., a slurry mixture of bean and/or corn meal and the protein supplement derived from the reprocessed animal waste is pumped by a central distributing pump and distributed into troughs disposed adjacent each of the animal confinement pens where it is made continuously available to the animals. In addition, a dome-shaped covering is provided over the tiered structure including a ventilation system which automatically maintains proper temperature and humidity levels within the enclosure at all times and provides for proper airflow within the enclosure so that each pen on each tier is properly ventilated at all times.
