Cooling Equipment Checks in time of Heat

To keep Your Cool, Maintain what keeps you Cool...

For the most part the equipment on most poultry buildings is well designed and is sized for the flock you housed.  But, just like your vehicle, these houses require normal maintenance checks to ensure optimal efficiency and long useful life.  Cooling pads need to be examined for proper distribution of water.  Reservoirs should be checked for proper fluid levels and condition of water.  Pump screens should be checked for algae or other obstructions that would limit flow.  Drain reservoirs that contain heavy sand / dirt that may accumulate near farm lanes.  Follow manufacture's recommendations for cleaning pads if you are in areas of hard water or notice residues forming on the pads.  During peak use, observe the pads to see that all areas are saturated to prevent hot air by-pass through the cell.  A small piece of wire or pipe cleaner is handy for unclogging cell water distribution pipes.  Be sure to have a few extra cells on site in case they are needed for replacement of cells damaged during load-out or de-lamination of the cell itself.  On the other side, be sure to power down and brush / blow off fan blades for proper operation.  Check belts and pulleys as you do this for proper adjustment and wear.  Proper weekly checks of the systems will ensure proper cooling when you need it.

The Importance of Shade in Hot Weather

Something That Casts Shade Can Be Vital

 When you think of it refrigeration cooling became popular during the 1950's when equipment could be sized to cool a house.  Even today, not all houses are air conditioned.  So even with large scale housing, some cooling effect can be made with plantings of trees near the houses.  By casting shadows on the houses, intake air temps are reduced and could mean the difference between life and death for a flock in high temp summer heat.

With smaller flocks, shade is a logical choice to cool the flock as it is cost effective and simple to set up.  a 4x8 sheet of plywood on sawhorses can offer ranging birds a place to get away from the radiational heating of direct sun.

If trees are not applicable, considering awnings and other roof extensions that will shade the inlets to the house.  Each of these structural changes will enhance cooling without undue higher cost.

Combating Heat Stress

Boy, is it hot out there!

With the recent heat wave moving through the US, we are all reminded of what we can do to make poultry more comfortable, and hopefully get them to survive.

Water is the saving elixir in heat. Due to its physical properties of heat energy, water can aid in the cooling of flocks. Flushing the watering lines with cool water may aid in getting hot birds to drink. Do not flush water lines for chicks as you risk the chance of cooling the chicks below their optimal core temperature.

In addition to flushing drinking lines/fonts, spraying the outside of the house (roof, sides and surrounding grounds) with water will drop the ambient temperature of the area a few degrees due to evaporative cooling. In humid climates this may not work well. To test, place a wick on a thermometer and dampen it with distilled water. The ability to cool with evaporation will be shown as the temperature will drop as it cools. Five degrees depressed temperature can make the difference in some flocks.

Shift some feedings to feed the birds during the coolness of the night if possible. Heat builds up in birds as they metabolize their feed. Cool air aids in getting birds to eat in hot periods.
