Eco-friendly livestock system of the present invention is a mixture of waste wood chips, livestock manure and mineral mixture flooring 110 fermented at room temperature for 45-60 days; A sawdust layer 120 formed on the flooring material; An injector 130 spaced upward from the sawdust layer 120 to inject a mixture of water or mineral mixture; An inclined portion 150 inclined at a predetermined angle to the lower portion of the housing system 100; and a drainage channel 140 connected to one end of the lower portion of the inclined portion 150. It forms the familiar environment below, and the excretion of livestock manure does not generate odor due to the purification function by the flooring material and the mineral mixture, and the livestock environment is kept clean and has the effect of reducing the possibility of disease in livestock. Accordingly, livestock manure does not need to be separately separated from the livestock manure because it is self-composting in the livestock environment, and the flooring 110 is maintained during the post-fermentation period of 1 to 2 years in which the growth and activation of its own microorganisms continues. There is no need to replace, since only the amount of reduction of the flooring material 110, which is reduced by the promotion of post-fermentation fermentation, needs to be partially compensated, the amount of labor is reduced, and the flooring material 110, which has expired after the fermentation period, is collected separately to produce high-quality organic fertilizer. It can be utilized, and can maintain a constant temperature throughout the four seasons by the fermentation heat of the flooring 110, thereby reducing the cost of the facility without the need for a separate heating and cooling device.본 발명의 친환경 축사 시스템은 폐목재칩, 가축분뇨 및 미네랄 혼합물을 혼합하여 실온에서 45~60일 동안 발효시킨 바닥재(110); 상기 바닥재 위에 형성된 톱밥 층(120); 상기 톱밥 층(120)으로부터 상부 방향으로 이격되어 물 또는 미네랄 혼합물 혼합 수용액을 분사하는 분사장치(130); 상기 축사 시스템(100)의 하부에 소정의 각도로 기울어진 경사부(150);및 상기 경사부(150)
