PROBLEM TO BE SOLVED: To provide an aerobic fermentation treatment method of excrement in an animal breeding floor, the method that has high fermentation performance without a bad smell, and is low in cost of equipment and running cost.SOLUTION: A method of this invention is provided as follows: many striped absorber materials 11 capable of being composted and absorbing moisture in animal's excrement are laid and levelled in the bulkiness of 400-700 mm on a breeding floor 3 to make an animal live and breed； a high-pressure air is blown and supplied from an air duct 4 having pipes laid on the floor surface side of the breeding floor 3 and including many nozzle holes 6a of small diameter in the absorber materials 11 being laid and levelled； and the absorber materials 11 containing the excrement on breeding floor 3 are fermented in a residence state of the animal. An air compressor is used as a generator of the high-pressure air, and it is preferable that the pressure of the high-pressure air may be 0.3 MPa or more.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】悪臭を伴わないで発酵性能が高く、設備費やランニングコストが低廉な動物飼育床における排泄物の好気性発酵処理方法を提供する。【解決手段】この発明の方法は、動物を居住させて飼育する飼育床３に、堆肥化可能で動物の排泄物中の水分を吸収する多数の細片状の吸収材１１を嵩高４００～７００ｍｍ敷き均し、上記飼育床３の床面側に配管され細径の多数のノズル孔６ａを備えた給気管４より上記敷き均された吸収材１１内に高圧エアを噴出させて供給し、前記動物の居住状態で飼育床３上の排泄物を含む吸収材１１を発酵させるものであり、高圧エアの発生装置としてエアコンプレッサーを用い、高圧エアの圧力が０．３ＭＰａ以上であることが望ましい。【選択図】図１
