Latest Poultry Housing Tip - Poultry House Leakage Estimator Spreadsheet
In order to control the environment within a poultry house it is essential that a producer not only controls how much ai is entering the house, but 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 center of th~ house to insure it is preconditioned by the warm air next to the ceiling before moving down to bird level. 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 maximize 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 minimize 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.
We have traditionally measured poultry house tightness by conducting a static pressure test. Questions often arise related to static pressure test results: What does a static pressure test value really mean? How much tighter is a house that obtains a 0.06" vs 0.12"? How does a static pressure affect my ability to ventilate my house during cold weather? What do I do if the air moving capacity of my static pressure test fan(s) does not meet the one cfm/ft2 of floor space requirement? Recently, an Excel spreadsheet was developed to help answer these questions as well as others related to house tightness testing
