Abstract: A barn for raising hogs includes walls, a roof, and a floor within the structure for supporting the hogs, the floor being solid such that materials on the floor settle on the floor without passing therethrough and being capable of supporting an animal and the floor including at least one sloped surface and a waste collection area at a lower end of the sloped surface and an animal feeding station adjacent an upper end of the sloped surface. A process is also taught for raising hogs it includes confining hogs on a solid floor, applying compostable, fibrous material to the solid floor, collecting manure-soiled fibrous material from the floor and composting the manure-soiled fibrous material to form a nutrient rich material suitable for use as a compost soil or soil supplement.

Abstract: A composting structure and process is described for a livestock operation. The structure handles manure and treats it over a continuous 25 to 30 day process to produce compost therefrom. The structure includes a elongate walled area into which manure is piled, aerated and mixed while it is moved toward an output end. The structure is sized to handle 25 to 30 days worth of manure from the livestock operation which it services. The aeration is provided by an in-floor system of tubes arranged in zones so that the amount of air injected in the various zones can be selected.
