An environment-friendly piggery comprises at least one circular or polyhedral piggery building. Each polyhedron has five sides or more, and a ventilation shaft is provided in the middle of each floor of each piggery building; each floor tilts from high to low towards the ventilation shaft from the outer edge; the top of each piggery building is provided with a exhaust gas collecting and treatment device communicating with the ventilation shaft; and the bottom of the buildings are provided with pig excreta collecting devices corresponding to the opening of the ventilation shaft. The piggery occupies a small area, has strong wind and snow resistant functions, and is sturdy and durable. The culturing process is pollution-free, and piglets, pigs, and sows can be accommodated appropriately.
