NOVELTY - A biological composition for processing animal waste, comprises a microorganism quantity, and a nutrient quantity sufficient to sustain reproduction of the microorganism for a reproduction period. The nutrient quantity comprises a supplement sufficient to nourish the microorganism for the reproduction period, a short term nutrient quantity and a long term nutrient quantity.    USE - The composition is used for processing animal waste (claimed). It is particularly used for treating animal waste in and near animal waste lagoons (27). The processed material may be drawn from the lagoon and distributed to plants.    ADVANTAGE - The composition can generate large amounts of desired microorganisms. It allows for faster processing of animal waste material. The microorganisms may also enhance the ability of the lagoon to prepare the waste for distribution to plants, enhancing the growth of vegetation.    DETAILED DESCRIPTION - A biological composition for processing animal waste, comprises a microorganism quantity, and a nutrient quantity sufficient to sustain reproduction of the microorganism for a reproduction period. The nutrient quantity comprises a supplement sufficient to nourish the microorganism for the reproduction period, a short term nutrient quantity and a long term nutrient quantity. The short term nutrient quantity is sufficient for sustain initial reproduction of at least the first generation of microorganisms, and at least a subsequent generation of microorganisms for an initial portion of the reproduction period. The long term nutrient quantity is sufficient to support microorganisms until the expiration of the reproduction period.    INDEPENDENT CLAIMS are also included for:    (1) growing microorganisms for processing animal waste, comprising providing a liquid mixture within a container, where the liquid mixture includes a water quantity, a microorganism quantity having an ability to process animal waste and a nutrient quantity; introducing oxygen into the liquid mixture; and circulating the liquid mixture; and    (2) treating an animal production facility, comprising providing a liquid mixture within the container, where the liquid mixture includes a water quantity, a microorganism quantity and a nutrient quantity; introducing oxygen into the liquid mixture; circulating the liquid mixture; extracting a liquid mixture portion from the container; introducing the liquid mixture portion into water in a cleaning system configured to apply fluid to surfaces of an animal production facility; and applying the combined liquid mixture portion and water to surfaces of an animal production facility.    DESCRIPTION OF DRAWING(S) - The figure shows a planar top view of a system configured to introduce microorganisms into a dairy milking parlor and accompanying lagoon.    Milking apparatus (16)    Parlor (20)    Barrier (25)    Lagoon (27)    Microorganism-generation tank (100)
