PROBLEM TO BE SOLVED: To prevent a decrease of a milking amount in summer by providing a cow barn comfortable for a cow in which the cow relatively resists cold because the first stomach of the cow has a high calorific value, however, stress rises during hot time in summer and the milking amount decreases.SOLUTION: A barn has a rectangular floor surface, a pair of sidewalls provided at the side of a long side of the floor surface, a pair of end walls provided at the side of a short side of the floor surface, and a roof disposed above the sidewalls and the end walls. The barn is characterized as follows: pull-side blowers are juxtaposed in the discharge direction at intervals of the diameters of adjacent blower fans or less over a length of the end wall in the first sidewall of the pair of sidewalls push-side blowers are disposed in the suction direction at the position opposed to the blower of both ends of the pull-side blowers, in the second sidewall of the pair of sidewalls and through-holes are provided between the push-side blowers.COPYRIGHT: (C)2015,JPO&INPIT【課題】牛の第1胃は発熱量が高いため、牛は寒さには比較的強いものの、夏季の暑い時期には、ストレスが高くなり、搾乳量が減少する。牛にとって快適な牛舎の提供が夏季の搾乳量の減少を防止する。【解決手段】長方形の床面と、前記床面の長辺側に設けられた一対の側壁と、前記床面の短辺側に設けられた一対の端壁と、前記側壁と前記端壁との上方に配置された屋根を有し、前記一対の側壁の第1側壁には、前記端壁の長さ以上に渡って、隣接する送風機のファンの直径以下の間隔で排出方向にプル側送風機が並設され、前記一対の側壁の第2側壁には、前記プル側送風機の両端の送風機に対向する位置に吸引方向にプッシュ側送風機が配設され、前記プッシュ側送風機の間には、貫通孔が設けられていることを特徴とする畜舎。【選択図】図1
