In order to control the environment within a PoultryHouse Barn, it is essential that a producer not only controls how much air is entering the house, but also where it is entering.
For instance, during cold weather essentially no air should enter a house when the fans are off. When the fans are operating, all the air should enter through the air inlets so it can be directed along the ceiling toward the centre of the house to ensure it is preconditioned by the warm air next to the ceiling before moving down to bird level. Curved Roof ceilings are the best way to achieve optimum efficiency in doing this. Air entering through cracks or gaps in side wall curtains whether the fans are on or off can lead to drafts, caked litter, and excessive fuel usage. During the summer, in order to maximise bird cooling all incoming air should enter through a house’s evaporative cooling pads. Air entering through cracks leads to hotter side walls, increased temperature differentials between the pads and fans, and poor air speed distribution, all of which can reduce weight gains and increase feed conversions. To minimise the problems associated with air leakage it is essential that poultry producers are aware of how tight their houses are so that corrections can be made before bird performance suffers and/or heating costs become excessive.
