EXAMPLE In FIG. 1, 80 m, four rows of cages 1
Are arranged in the poultry house in the longitudinal direction, and an air inlet 3 is provided in a left end of the figure and a part of the longitudinal side walls 2 near the end face. In the illustrated embodiment, the air inlet 3 is It is covered with the cooling pad 4 and shielded from light. Since the cooling pad 4 is made of a material capable of absorbing water, such as paper or non-woven fabric, if the whole is impregnated with water by flowing or dropping water from above, the cooling pad 4 will naturally flow from the inlet 3. The introduced air can be cooled while passing through it, and its temperature can be lowered, and it is particularly effective when used in the summer when the outside temperature is high. The air from the air inlet 3 flows as shown by the arrow and is supplied to the birds in the cage to be warmed by the body temperature of the birds, and by the exhaust fan 6 attached to the exhaust port 5 on the right side of the figure. , Forcibly released into the atmosphere.

FIG. 2 shows these end faces.
It is well understood that in A, the cooling pad 4 covers the end face 3 of the end face, and in FIG. 2B, the exhaust fan 6 is attached to the end face 5 of the end face. In addition, except during summer when the temperature is high, water does not flow down or drip on the cooling pad 4, and it is not used for cooling when taking in air, but the air inlet 3 is always covered with the cooling pad and the outside air It is introduced into the poultry house through this.

An auxiliary air intake port 7 extending to the upper portion of both side walls 2 is provided between a substantially central portion of the both side walls 2 in the longitudinal direction and an end portion 1a of the cage row 1 which is located downstream of the center portion and is close to the exhaust fan 6. . As shown in FIG. 3, the auxiliary air inlet 7 of this embodiment is provided between the roof 8 and the side walls 2 with the upper portions of the side walls 2 shortened. Then, open and close with the lower end as the axis) and adjust the opening and closing to change the amount of air introduced into the poultry house. A signal from a temperature sensor (not shown) provided in the poultry house before and after the auxiliary air inlet (downstream and upstream), for example, between cage rows, is used for opening / closing and adjusting the opening of the air inlet adjusting plate 9. Done by
It is effective to use the auxiliary air inlet 7 in the season when the cooling by the cooling pad 4 is not performed, especially in winter when the temperature difference between the air inlet and the exhaust outlet tends to be large. The temperature of the air once warmed is lowered by the inflow of the auxiliary air from the auxiliary air inlet, so that the temperature in the poultry house can be maintained close to uniform.

When the length of the cage row is further increased, it is difficult to adequately ventilate the inside of the poultry house by taking in air from one of the gable faces. Therefore, an air inlet is provided at approximately the center of both side walls in the longitudinal direction. A method is adopted in which the air taken in is discharged from both gable surfaces. FIG. 4 shows the method, and an air inlet 13 is provided at approximately the center of both longitudinal side walls 12 of the poultry house. The air inlet 13 is covered with a cooling pad 14 as in FIG. It is being appreciated. An exhaust fan 16 is attached to the exhaust ports 15 on both sides of the poultry house, and the air taken in from the intake port 13 flows as shown by the arrows and is supplied to the birds in the cage while warming up with the birds' body temperature. Then, the exhaust fans 16 on both end faces of the drawing forcefully discharge the air to the outside atmosphere.

In the case of the embodiment of FIG. 4, the auxiliary air inlet 17
Is the exhaust fan 1 from the air inlet 13 at the upper side of both side walls in the longitudinal direction.
About the middle of the distance up to 6 and at least the cage row 11
Is provided so as to extend up to a portion corresponding to the end portion 11a close to the exhaust fan 16. Auxiliary air inlet 17
The adjustment of the air intake adjusting plate (not shown) at the outlet of is performed in the same manner as in the case of FIG. Further, in the two embodiments described above, a vertical wall surface is provided below the poultry house so that the poultry house has two longitudinal walls.
By dividing into rooms, birds with different growth levels can be housed in each room and effective ventilation can be performed, as in a normal poultry house.

Further, as shown in FIG. 3, the straightening vanes 10 are hung on the row of cages, or although not shown, a ceiling is stretched over the cages and similar to an air supply slit from an ordinary ceiling duct. By providing slits along the longitudinal direction on the ceiling above the cage rows, the air from the auxiliary air inlet 7 can be easily supplied into the cage rows.
