A multilayer three-dimensional culture system for livestock and poultry comprises an annular building having more than two stories. The outer diameter of each upper-layer annular building is smaller than the outer diameter of each lower-layer annular building, so that the annular building forms a step-type structure; houses (6) are arranged in the annular step-type building, the houses (6) are connected to sports fields (7), each house (6) is located on the inner side of the corresponding annular step-type building layer, and the sports fields (7) are located on the outer side of the corresponding annular step-type building layer; animal walking surfaces of the houses (6) and the sports fields (7) are hollowed-out surfaces, excrement and urine collecting chambers (27) are arranged under the hollow-out surfaces and are communicated with a sewage treatment pond by means of pipelines, and excrement cleaning machines (28) are mounted in the excrement and urine collecting chambers (27); a feed conveying device (22) and a drinking water device (23) are mounted in the annular step-type building, and the annular step-type building is connected to a helical ramp (3); the helical ramp (3) gradually rises from the bottom end to the top story along each story on the inner side of the annular step-type building, and allows animals to walk in or out of the houses (6). The culture system allows an automatic device to be easily realized, and can also ensure illumination demands of the livestock and the poultry. |
