Broiler Breeder Cool Cell Operation
April 19th, 2011 by Grow With Tyson

This newsletter (PDF download) from the University of Georgia College of Agricultural and Environmental Sciences Cooperative Extension discusses how to best operate cool cell systems in breeder houses to achieve maximum bird cooling.

Without sufficient wind speed moving over the birds when the evaporative cooling system is operating, the pads may be less beneficial than one thinks, and possibly even hurt bird performance. This in no way means that evaporative cooling pads should not be used to keep our birds cool but simply they are the last step in the cooling process. But, if you want to insure maximum bird cooling, basically all of a house’s tunnel fans should be operating before water is added to the evaporative cooling pads. And once a pad system is operating it is essential that none of the fans shut off until house temperature has dropped to the point where the birds are no longer in risk of becoming heat stressed. For example, during hot weather a house’s evaporative cooling pads should typically be set to come on between 83oF and 85oF (setting the pads to operate much lower than this will typically produce little cooling and result in a relative humidity of 90% or greater). All the house’s tunnel fans would be operating by approximately 80oF and set not to shut off until the house temperature (at the tunnel fan end of the house) dropped to 77oF, or lower . . .
