PROBLEM TO BE SOLVED: To provide a livestock barn which is comfortable for cows and prevent decrease in milking amount in summer, as cows have high calorific power generated in a first stomach which allows them to be strong in cold while increase stress and lead to decrease in milking amount in hot summer.SOLUTION: A livestock barn includes: a rectangular floor a pair of side walls 14a, 14b provided on long sides of the floor a pair of end walls 12a, 12b provided on short sides of the floor and a roof 16 provided on the side walls 14a, 14b and the end walls 12a, 12b. A pull-side fan is provided on a first side wall, one of the pair of the side walls, and a push-side fan is provided on a second side wall, the other of the pair of the side walls. There are also provided: a temperature sensor for measuring an inside temperature of the livestock barn a communication device which receives individual signal from an individual information terminal attached to livestock belonging to the livestock barn and a controller which controls a rotational speed of the fan based on at least one of the inside temperature and the individual signal.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,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。夏季の搾乳量の減少を防止する牛にとって快適な牛舎を提供する。【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14a、14bと、前記床面の短辺側に設けられた一対の端壁12a、12bと、側壁14a、14bと端壁12a、12bとの上方に配置された屋根16を有し、一対の側壁の第1側壁には、プル側送風機が並設され、一対の側壁の第2側壁には、プッシュ側送風機が配設され、畜舎の舎内温度を測定する温度センサと、前記畜舎に属する家畜に装着された個体情報端末からの個体信号を受信する通信装置と、前記舎内温度と前記個体信号の少なくとも1つに基づいて前記送風機の回転数を制御する制御器を有することを特徴とする畜舎。【選択図】図1
