- the livestock barn system is required to maintain a good breeding environment for livestock.
- livestock For example, in a poultry farming system, it is necessary to take measures against cold in winter and heat in summer to maintain a good breeding environment for chickens.
- newly born juveniles need to be reared in a high temperature and windless environment near body temperature because they are fragile.
- Examples of methods for heating the livestock house include warm air heating and blueder heating.
- Warm air heating is not preferable because it will take the temperature of the juveniles by irradiating the juveniles with wind.
- a fossil fuel is used for Bruder heating, a carbon dioxide will generate
- the gas blueder method used for heating local heating occurs, so the temperature of the bedding (flooring) becomes nonuniform, and the condition of the bedding (flooring) deteriorates.

- the heated first medium circulates through the plurality of second pipes 33.
- the temperature of the floor surface 11 can be obtained by providing an appropriate difference between the flow rates of the first medium flowing through the plurality of second pipes 33 by the adjusting valve V7. Can make a difference.
- the present invention is applied to a poultry farming system that breeds chickens as a livestock house system, but can also be applied to breeding of pigs and the like.
- the positioning unit 34 positions the second pipe 33 so that the distance from the floor surface 11 is constant.
- the positioning unit 34 may position the second pipe 33 so that the distance from the floor surface 11 differs depending on the place. According to this configuration, it is possible to generate a temperature gradient on the floor surface 11 according to the depth from the floor surface 11. Thus, the chicken can move to a place where the temperature environment is more favorable.
