Minimum ventilation

As discussed in last month’s Poultry Housing Tips, an inlet that draws air from the attic space of a dropped ceiling house during cold weather has a number of potential advantages over traditional side wall inlets. The most valuable of which is that attic temperatures are often significantly higher than outside temperatures even during cold weather. By drawing in preheated air from the attic space, ventilation rates should be able to be increased, leading to improved air quality, drier litter and possibly lower heating costs. The key word here is “should”. There are still many questions yet to be answered before we know whether or not attic inlets are a cost effective option for the typical broiler house.
