The present invention relates to a converged system for livestock production, which includes: a hemispherical shade (20) which is installed on the ground for guiding sunlight to a livestock field which is formed underground； a greenhouse (10) which is arranged in the periphery of the shade (20) to culture plants therein and has a solar cell module (12) to generates power using incident sunlight at a roof (11)； a livestock shed (30) which is formed underground, which is the lower part of the greenhouse, to rear livestock and is connected to a livestock field (21) so that the livestock can use the livestock field and sunlight can be received； an excrement processing unit (60) which is formed underground, which is the lower part of the livestock shed (30), receives and methane-ferments the livestock excrement collected in the livestock shed (30), uses the livestock excrement as a fermenting agent for biofiltration or liquid-fertilizes the livestock excrement, and collects biogas generated after methane-fermenting； a ventilation unit (40) which has an inlet (42) exposed to the ground surface to supply air with temperature increased by geothermal by guiding the air on the surface underground and an outlet (43) which is exposed to the bottom surface of the livestock shed through the underground； a rain water collection tank (90) which is installed in the periphery of the livestock to collect rain water on the surface and use as cleaning water, maintenance water for the livestock shed and supply water for plants in the greenhouse； and a combined heat and power which is formed underground, which is a lower part of the livestock field, and generates electricity and heat using the biogas generated in the excrement processing unit.본 발명은 융복합 축산시스템에 관한 것으로, 이를 위해 지중에 형성된 가축필드(21)로 태양광이 입사될 수 있도록 지상에 설치되는 차광가능한 반구형의 채광막(20)；과, 상기 채광막(20)의 둘레에 배치되어 내부로는 식물이 재배될 수 있도록 하고, 지붕(11)에는 입사되는 태양광에 의해 전력을 생산할 수 있도록 솔라셀모듈(12)이 설치되는 온실(10)；과, 가축을 사육할 수 있도록 상기 온실(10)의 하부영역인 지중에 형성되고, 가축이 가축필드
