As a structure separately controlling the opening and closing of a first path including a cooling flow path (114) defined as a gap between an inside housing (111) and an outside housing (113) and a second path communicating with the cooling flow path (114) through the inside of the inside housing (111) through a ventilation section (115) provided inside the inside housing (111), a feed storage silo for use in a pigsty of a piglet farm according to the present invention is operated in: a first operation state where a first outflow and inflow section (h1) communicating with the outside and the cooling flow path (114) are allowed to communicate with each other and the first outflow and inflow section (h1) and the ventilation section (115) are allowed to communicate with each other by a flow path control unit (120) a second operation state where the first outflow and inflow section (h1) and the cooling flow path (114) are blocked from each other and the first outflow and inflow section (h1) and the ventilation section (115) are allowed to communicate with each other by the flow path control unit (120) a third operation state where the flow path control unit (120) performs control such that the degree of communication between the first outflow and inflow section (h1) and the cooling flow path (114) and the degree of communication between the first outflow and inflow section (h1) and the ventilation section (115) are in inverse proportion to each other and a fourth operation state where the first outflow and inflow section (h1) and the cooling flow path (114) are allowed to communicate with each other and the first outflow and inflow section (h1) and the ventilation section (115) are blocked from each other by the flow path control unit (120).COPYRIGHT KIPO 2017내측 하우징(111)과 외측 하우징(113) 사이의 간격으로 정의되는 냉각유로(114)를 포함하는 제1 경로와, 상기 내측 하우징(111)의 내측으로 구비되는 환기부(115)를 통하여 상기 내측 하우징(111)의 내부를 거쳐 상기 냉각유로(114)로 연통되는 제2 경로의 개폐를 각각 제어하는 구조로서, 본 발명에 따른 자돈농장 축사용 사료저장조는 유로제어부(120)가, 외부와 연통
