<p>PROBLEM TO BE SOLVED: To improve a pigpen structure including an excrement treatment and floor heating for piglets in chambers of a pigpen.SOLUTION: Each floor of multiple chambers provided in a pigpen is formed of a floor having apertures such as meshes that allow excrement to drop, an excrement tank for reserving the dropped excrement is provided under the floor, and a washing device is provided so as to cause the excrement to flow down to a septic tank through a sewer pipe formed at the bottom surface of the excrement tank 5 by supplying water to the excrement tank 5 at constant time intervals. A heating floor mat for piglets installed in each of the chambers of the pigpen is formed by: embedding a macromolecular polymer heat pipe in a concrete block; connecting one end thereof to a heat medium introduction port of a heating unit; and connecting the other end thereof to a heat medium recovery port. Corner parts of side and upper surfaces of the concrete block are chamfered into a curved shape.</p> |
