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. |
