This investigation evaluated the potential of aerobic stabilization to increase the value of animal manures as feedstuffs. Laboratory scale batch and continuous flow studies using laying hen manure as a substrate were conducted. The batch studies conducted were for periods of 15 and 10 days. Completely, mixed continuous flow reactors were operated at retention time of 3, 5, 7, and 10 days. Results from both sets of studies indicated that the essential amino acid content and thus the potential value of laying hen manure as a feedstuff can be substantially increased with short-term aeration. Aerobically stabilized laying hen manure appears to be a well-balanced source of the essential amino acids required by White Leghorn laying hens. Such stabilized manure generally is comparable to soybean meal in essential amino acid composition. This process appears to be adequate to justify the cost of aeration for waste stabilization and odor control.
