A thermostat is an important part of the ventilating sys
tem, as is being demonstrated here. Air flow requirements
will vary as weather conditions change. You can provide
for these varying requirements by setting the thermostats
to cut fans off as temperatures drop. In buying a thermo
stat, make certain it is a heavy duty unit. Buy only a farm
type thermostat that's dust-proof.
Here's a ventilation system that works well for this Indiana poultryman. When
installing exhaust fans, always make certain they are in the wall away from
prevailing winds. Otherwise, outside wind pressures will greatly reduce the effi
ciency of your ventilation system. Keep the fan motor dusted off and belts in
proper adjustment. This can save you several dollars in needless repair bills.

These two pictures show how adequate ventilation in the laying house can pro
duce more desirable conditions for profitable egg production. The photo at left
shows how litter can become wet and crusted when there is insufficient ventilation.
Studies have shown this is one of the major reasons for dirty eggs. The photo at
right was taken in a laying house that was properly ventilated. Notice how the
litter is dry and fine. Birds in this house can be expected to perform much more
profitably than when the house is damp and foul smelling. -
Don't overlook the need for
adequate ventilation in
dairy calf quarters. In fact,
ventilation management
can be more critical here
than in other livestock
buildings. Young animals
have little resistance to
stress. When pens become
damp, disease problems in
crease. Also, you'll want to
be careful in controlling air
flow. If using some natural
ventilation, as shown, make
certain there are no drafts.
Ventilation is an important aspect of producing milk in
comfortable surroundings. This is the milk room of the
Sprecher Brothers dairy operation in south central Wiscon
sin. The fan shown just above Merlin Sprecher does a good
job in removing excess moisture from the milk room. Mer
lin and his brother Loren both agree that adequate venti
lation is an important part of profitable milk production.
